下面参考附图描述根据本实用新型实施例的换热器10。A heat exchanger 10 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.
如图1-图8所示，根据本实用新型实施例的换热器10，包括换热管1和多个间隔开的翅片2。As shown in FIG. 1 to FIG. 8 , a heat exchanger 10 according to an embodiment of the present invention includes a heat exchange tube 1 and a plurality of spaced-apart fins 2 .
具体地，参考图1-图8，换热管1包括过冷管11和蒸发管12，每个翅片2包括在翅片2的长度方向上排布的第一翅片部21和第二翅片部22，过冷管11穿设于第一翅片部21上，蒸发管12穿设于第二翅片部22上，第一翅片部21上的过冷管11连接后形成过冷流路3，第二翅片部22上的蒸发管12连接后形成换热流路4，过冷流路3和换热流路4之间能够换热，在第一模式，制冷剂由过冷流路3流向换热流路4，换热流路4的出口端43位于第二翅片部22的靠近第一翅片部21的一端。Specifically, referring to Figures 1 to 8, the heat exchange tube 1 includes a subcooling tube 11 and an evaporating tube 12, each fin 2 includes a first fin portion 21 and a second fin portion 22 arranged in the length direction of the fin 2, the subcooling tube 11 is passed through the first fin portion 21, and the evaporating tube 12 is passed through the second fin portion 22. The subcooling tubes 11 on the first fin portion 21 are connected to form a subcooling flow path 3, and the evaporating tubes 12 on the second fin portion 22 are connected to form a heat exchange flow path 4. Heat can be exchanged between the subcooling flow path 3 and the heat exchange flow path 4. In the first mode, the refrigerant flows from the subcooling flow path 3 to the heat exchange flow path 4, and the outlet end 43 of the heat exchange flow path 4 is located at one end of the second fin portion 22 close to the first fin portion 21.
可以理解的是，翅片2为沿翅片2厚度方向间隔开的多个，换热管1穿设于多个翅片2中，在第一模式，液管400与过冷管11连接，液管400中具有已经被过冷后的液相制冷剂，而过冷流路3用于给已经被过冷后的制冷剂再次降温过冷，再由过冷流路3流向换热流路4，从而可以提高换热器10的换热效率，提高制冷效果，液相制冷剂在换热流路4中不断蒸发，形成气液两相制冷剂或气相制冷剂，流向换热流路4的出口端43，同时出口端43与气管500连接，使得制冷剂可以流向气管500，其中，在本实用新型中，第一模式为制冷模式，换热流路4为蒸发流路。It can be understood that the fins 2 are multiple and spaced apart along the thickness direction of the fins 2, and the heat exchange tube 1 is inserted into the multiple fins 2. In the first mode, the liquid pipe 400 is connected to the supercooling pipe 11. The liquid pipe 400 contains liquid-phase refrigerant that has been supercooled, and the supercooling flow path 3 is used to cool the supercooled refrigerant again, and then flow from the supercooling flow path 3 to the heat exchange flow path 4, thereby improving the heat exchange efficiency of the heat exchanger 10 and improving the refrigeration effect. The liquid-phase refrigerant continuously evaporates in the heat exchange flow path 4 to form a gas-liquid two-phase refrigerant or a gas-phase refrigerant, and flows to the outlet end 43 of the heat exchange flow path 4. At the same time, the outlet end 43 is connected to the gas pipe 500, so that the refrigerant can flow to the gas pipe 500. In the utility model, the first mode is the refrigeration mode, and the heat exchange flow path 4 is the evaporation flow path.
进一步地，如图1-图8所示，在第一模式，换热流路4的出口端43位于第二翅片部22的靠近第一翅片部21的一端，从而使得换热流路4的出口端43与过冷流路3相邻，从而在第一模式，便于换热流路4的出口端43的气液两相制冷剂或气相制冷剂与过冷流路3流中的液相制冷剂换热，由于过冷流路3流中的液相制冷剂的温度高于出口端43的制冷剂，从而使得过冷流路3流中的液相制冷剂可以给出口端43的制冷剂加热，从而使得出口端43的气液两相制冷剂中的液相制冷剂继续蒸发，从而便于出口端43的气液两相制冷剂转变为气相制冷剂，从而减少制冷剂回流，从而提高换热器10的换热效率。Further, as shown in Figures 1 to 8, in the first mode, the outlet end 43 of the heat exchange flow path 4 is located at one end of the second fin portion 22 close to the first fin portion 21, so that the outlet end 43 of the heat exchange flow path 4 is adjacent to the subcooling flow path 3, so that in the first mode, it is convenient for the gas-liquid two-phase refrigerant or the gas-phase refrigerant at the outlet end 43 of the heat exchange flow path 4 to exchange heat with the liquid-phase refrigerant in the subcooling flow path 3. Since the temperature of the liquid-phase refrigerant in the subcooling flow path 3 is higher than the refrigerant at the outlet end 43, the liquid-phase refrigerant in the subcooling flow path 3 can heat the refrigerant at the outlet end 43, so that the liquid-phase refrigerant in the gas-liquid two-phase refrigerant at the outlet end 43 continues to evaporate, thereby facilitating the conversion of the gas-liquid two-phase refrigerant at the outlet end 43 into the gas-phase refrigerant, thereby reducing the refrigerant reflux, thereby improving the heat exchange efficiency of the heat exchanger 10.
在第一模式时，制冷剂在换热器10中的流路为：液相制冷剂从液管400流向过冷流路3，液相制冷剂在过冷流路3中降温过冷，进入换热流路4进行换热，液相制冷剂在换热流路4中不断蒸发，形成气液两相制冷剂或气相制冷剂，流向换热流路4的出口端43，换热流路4的出口端43中的制冷剂与过冷流路3中的制冷剂换热，并使得换热流路4的出口端43中的制冷剂过热，使得换热流路4的出口端43中气液两相制冷剂的液相制冷剂继续挥发为气相制冷剂，最后流向气管500。In the first mode, the flow path of the refrigerant in the heat exchanger 10 is: the liquid refrigerant flows from the liquid pipe 400 to the supercooling flow path 3, the liquid refrigerant is cooled and supercooled in the supercooling flow path 3, and enters the heat exchange flow path 4 for heat exchange, the liquid refrigerant continuously evaporates in the heat exchange flow path 4 to form a gas-liquid two-phase refrigerant or a gas-phase refrigerant, and flows to the outlet end 43 of the heat exchange flow path 4, the refrigerant in the outlet end 43 of the heat exchange flow path 4 exchanges heat with the refrigerant in the supercooling flow path 3, and the refrigerant in the outlet end 43 of the heat exchange flow path 4 is superheated, so that the liquid refrigerant of the gas-liquid two-phase refrigerant in the outlet end 43 of the heat exchange flow path 4 continues to evaporate into a gas-phase refrigerant, and finally flows to the gas pipe 500.
其中，在本实用新型中，第一翅片部21和第二翅片部22为一体件，由此，可以简化结构，提高生产效率。Among them, in the present invention, the first fin portion 21 and the second fin portion 22 are an integrated part, thereby simplifying the structure and improving production efficiency.
根据本实用新型实施例的换热器10，通过过冷管11穿设于第一翅片部21上，蒸发管12穿设于第二翅片部22上，第一翅片部21上的过冷管11连接后形成过冷流路3，第二翅片部22上的蒸发管12连接后形成换热流路4，在第一模式，制冷剂由过冷流路3流向换热流路4，换热流路4的出口端43位于第二翅片部22的靠近第一翅片部21的一端。从而使得换热流路4的出口端43与过冷流路3相邻，从而便于换热流路4的出口端43的制冷剂与过冷流路3流中的制冷剂换热，从而在第一模式，便于出口端43的气液两相制冷剂转变为气相制冷剂，减少制冷剂回流，从而可以提高换热器10的换热效率。According to the heat exchanger 10 of the embodiment of the utility model, the subcooling tube 11 is provided on the first fin part 21, and the evaporation tube 12 is provided on the second fin part 22. The subcooling tube 11 on the first fin part 21 is connected to form a subcooling flow path 3, and the evaporation tube 12 on the second fin part 22 is connected to form a heat exchange flow path 4. In the first mode, the refrigerant flows from the subcooling flow path 3 to the heat exchange flow path 4, and the outlet end 43 of the heat exchange flow path 4 is located at one end of the second fin part 22 close to the first fin part 21. Therefore, the outlet end 43 of the heat exchange flow path 4 is adjacent to the subcooling flow path 3, so that the refrigerant at the outlet end 43 of the heat exchange flow path 4 is convenient for heat exchange with the refrigerant in the subcooling flow path 3, so that in the first mode, the gas-liquid two-phase refrigerant at the outlet end 43 is convenient for conversion into gas-phase refrigerant, reducing the refrigerant reflux, thereby improving the heat exchange efficiency of the heat exchanger 10.
在本实用新型的一些实施例中，如图1-图8所示，在第二模式，制冷剂由换热流路4流向过冷流路3，所述换热流路4的进口端位于所述第二翅片部22的靠近所述第一翅片部21的一端；其中，所述第一模式与所述第二模式的制冷剂流向相反。In some embodiments of the present invention, as shown in Figures 1 to 8, in the second mode, the refrigerant flows from the heat exchange flow path 4 to the subcooling flow path 3, and the inlet end of the heat exchange flow path 4 is located at an end of the second fin portion 22 close to the first fin portion 21; wherein the refrigerant flow direction of the first mode is opposite to that of the second mode.
可以理解的是，在本实用新型中，第一模式为制冷模式，第二模式则为制热模式，从而实现空调室内机100的制热。It can be understood that, in the present invention, the first mode is a cooling mode, and the second mode is a heating mode, thereby achieving heating of the air-conditioning indoor unit 100 .
在第二模式时，换热流路4为冷凝流路，冷凝流路的入口为第一模式下换热流路4的出口端43，换热流路4的入口端42为冷凝流路的出口。由此，在第一模式时，制冷剂在换热器10中的流路为：制冷剂从气管500流向冷凝流路的入口，并进入冷凝流路，经过在冷凝流路中换热后，制冷剂从冷凝流路的出口流出，并经过过冷流路3的过冷，最后流向液管400。In the second mode, the heat exchange flow path 4 is a condensation flow path, the inlet of the condensation flow path is the outlet end 43 of the heat exchange flow path 4 in the first mode, and the inlet end 42 of the heat exchange flow path 4 is the outlet of the condensation flow path. Therefore, in the first mode, the flow path of the refrigerant in the heat exchanger 10 is: the refrigerant flows from the gas pipe 500 to the inlet of the condensation flow path, and enters the condensation flow path. After heat exchange in the condensation flow path, the refrigerant flows out from the outlet of the condensation flow path, and is subcooled by the subcooling flow path 3, and finally flows to the liquid pipe 400.
在本实用新型的一些实施例中，如图1-图8所示，在第一模式，换热流路4的入口端42位于第二翅片部22背离第一翅片部21的一端，且换热流路4内的制冷剂由第二翅片部22背离第一翅片部21的一端流向第二翅片部22的靠近第一翅片部21的一端。In some embodiments of the present invention, as shown in Figures 1 to 8, in the first mode, the inlet end 42 of the heat exchange flow path 4 is located at the end of the second fin portion 22 away from the first fin portion 21, and the refrigerant in the heat exchange flow path 4 flows from the end of the second fin portion 22 away from the first fin portion 21 to the end of the second fin portion 22 close to the first fin portion 21.
可以理解的是，在第一模式，换热流路4的入口端42位于第二翅片部22背离第一翅片部21的一端，换热流路4的出口端43位于第二翅片部22的靠近第一翅片部21的一端，从而使得换热流路4内的制冷剂由第二翅片部22背离第一翅片部21的一端流向第二翅片部22的靠近第一翅片部21的一端，从而使得换热流路4可以沿第二翅片部22的长度方向的覆盖第二翅片部22，从而提高了换热器10的效率。同时，换热流路4的入口端42和出口端43分别位于第二翅片部22的长度方向的两端，使得换热流路4的入口端42和出口端43间隔距离远，从而可以减小换热流路4的入口端42和出口端43中的制冷剂相互传热，进一步地提高了换热器10的效率。It can be understood that in the first mode, the inlet end 42 of the heat exchange flow path 4 is located at the end of the second fin part 22 away from the first fin part 21, and the outlet end 43 of the heat exchange flow path 4 is located at the end of the second fin part 22 close to the first fin part 21, so that the refrigerant in the heat exchange flow path 4 flows from the end of the second fin part 22 away from the first fin part 21 to the end of the second fin part 22 close to the first fin part 21, so that the heat exchange flow path 4 can cover the second fin part 22 along the length direction of the second fin part 22, thereby improving the efficiency of the heat exchanger 10. At the same time, the inlet end 42 and the outlet end 43 of the heat exchange flow path 4 are respectively located at the two ends of the length direction of the second fin part 22, so that the inlet end 42 and the outlet end 43 of the heat exchange flow path 4 are separated by a long distance, thereby reducing the heat transfer between the refrigerants in the inlet end 42 and the outlet end 43 of the heat exchange flow path 4, and further improving the efficiency of the heat exchanger 10.
其中，在第一模式，换热流路4的出口端43可以位于第二翅片部22的上端设置，也可以是换热流路4的出口端43位于第二翅片部22的下端设置。例如在图1-图4所示的示例中，第一翅片部21相对于第二翅片部22靠近换热器10的上端设置，换热流路4的入口端42位于第二翅片部22的下端设置，换热流路4的出口端43位于第二翅片部22的上端设置。例如在图5-图8所示的示例中，换热流路4的入口端42位于第二翅片部22的上端设置，换热流路4的出口端43位于第二翅片部22的下端设置。Among them, in the first mode, the outlet end 43 of the heat exchange flow path 4 can be located at the upper end of the second fin part 22, or the outlet end 43 of the heat exchange flow path 4 can be located at the lower end of the second fin part 22. For example, in the examples shown in Figures 1 to 4, the first fin part 21 is arranged near the upper end of the heat exchanger 10 relative to the second fin part 22, the inlet end 42 of the heat exchange flow path 4 is arranged at the lower end of the second fin part 22, and the outlet end 43 of the heat exchange flow path 4 is arranged at the upper end of the second fin part 22. For example, in the examples shown in Figures 5 to 8, the inlet end 42 of the heat exchange flow path 4 is arranged at the upper end of the second fin part 22, and the outlet end 43 of the heat exchange flow path 4 is arranged at the lower end of the second fin part 22.
在本实用新型的一些实施例中，如图1和图5所示，换热管1为一排，多个换热管1在翅片2的长度方向上间隔排布。可以理解的是，换热管1为一排可以使得翅片2的宽度小，从而可以优化换热器10内部空间，有利于换热器10的轻量化，同时使得换热器10结构简单，成本低。In some embodiments of the present invention, as shown in Figures 1 and 5, the heat exchange tubes 1 are arranged in a row, and a plurality of heat exchange tubes 1 are arranged at intervals in the length direction of the fins 2. It can be understood that the heat exchange tubes 1 are arranged in a row so that the width of the fins 2 is small, thereby optimizing the internal space of the heat exchanger 10, which is conducive to the lightweight of the heat exchanger 10, and at the same time makes the heat exchanger 10 simple in structure and low in cost.
在本实用新型的一些实施例中，如图1和图5所示，第二翅片部22上的多个换热管1沿翅片2的长度方向依次串接连接构成换热流路4。由此，换热流路4为一条，从而进一步地优化换热器10内部空间，有利于换热器10的轻量化，同时使得换热器10结构简单，成本低。In some embodiments of the present invention, as shown in Figures 1 and 5, a plurality of heat exchange tubes 1 on the second fin portion 22 are sequentially connected in series along the length direction of the fin 2 to form a heat exchange flow path 4. Thus, the heat exchange flow path 4 is one, thereby further optimizing the internal space of the heat exchanger 10, which is beneficial to the lightness of the heat exchanger 10, and at the same time makes the heat exchanger 10 simple in structure and low in cost.
在本实用新型的一些实施例中，如图2-图4和图6-图8所示，换热管1为在翅片2的宽度方向上间隔设置的多排，每排换热管1包括在翅片2的长度方向上间隔设置的多个换热管1。由此，制冷剂可以在多排换热管1中流动换热，从而可以提高换热器10的换热效率。In some embodiments of the present invention, as shown in Figs. 2-4 and 6-8, the heat exchange tubes 1 are arranged in multiple rows at intervals in the width direction of the fins 2, and each row of heat exchange tubes 1 includes multiple heat exchange tubes 1 arranged at intervals in the length direction of the fins 2. Thus, the refrigerant can flow and exchange heat in the multiple rows of heat exchange tubes 1, thereby improving the heat exchange efficiency of the heat exchanger 10.
例如在图2和图6所示的示例中，换热管1为在翅片2的宽度方向上间隔设置的两排，例如在图3和图7所示的示例中，换热管1为在翅片2的宽度方向上间隔设置的三排，例如在图4和图8所示的示例中，换热管1为在翅片2的宽度方向上间隔设置的四排，但是本实用新型并不限于此，换热管1可以为在翅片2的宽度方向上间隔设置的更多排，例如5排、6排、7排或8排等。For example, in the examples shown in Figures 2 and 6, the heat exchange tubes 1 are arranged in two rows at intervals in the width direction of the fin 2. For example, in the examples shown in Figures 3 and 7, the heat exchange tubes 1 are arranged in three rows at intervals in the width direction of the fin 2. For example, in the examples shown in Figures 4 and 8, the heat exchange tubes 1 are arranged in four rows at intervals in the width direction of the fin 2. However, the utility model is not limited to this. The heat exchange tubes 1 can be arranged in more rows at intervals in the width direction of the fin 2, such as 5 rows, 6 rows, 7 rows or 8 rows, etc.
在本实用新型的一些实施例中，如图2-图4和图6-图8所示，换热流路4包括并联的多个蒸发子流路41，多个蒸发子流路41的数量与换热管1的排数相同。可以理解的是，多个并联的蒸发子流路41使得制冷剂可以同时在多条蒸发子流路41中流动，从而提高了制冷剂的流动效率，从而进一步地提高了换热器10的换热效率。In some embodiments of the present invention, as shown in Fig. 2-Fig. 4 and Fig. 6-Fig. 8, the heat exchange flow path 4 includes a plurality of evaporation sub-flow paths 41 connected in parallel, and the number of the plurality of evaporation sub-flow paths 41 is the same as the number of rows of the heat exchange tubes 1. It can be understood that the plurality of parallel evaporation sub-flow paths 41 allow the refrigerant to flow in the plurality of evaporation sub-flow paths 41 at the same time, thereby improving the flow efficiency of the refrigerant, and further improving the heat exchange efficiency of the heat exchanger 10.
进一步地，在第一模式，每个蒸发子流路41的出口端43均设于第二翅片部22的靠近第一翅片部21的一端。由于在第一模式中，制冷剂在各个蒸发子流路中的换热不均匀，从而使得制冷剂流至各个蒸发子流路的出口端时，各个蒸发子流路的出口端温度不均，部分蒸发子流路的出口端中的制冷剂未挥发完全，易导致回流，从而使得换热器性能下降。而在第一模式，每个蒸发子流路41的出口端43均设于第二翅片部22的靠近第一翅片部21的一端，从而使得每个蒸发子流路41的出口端43均与过冷流路3相邻，从而便于各个蒸发子流路41的出口端43的制冷剂与过冷流路3流中的制冷剂换热，温度过低的蒸发子流路41的出口端43中的制冷剂可以被加热，使得其中的液态制冷剂继续挥发，减少回流，由此，均衡了各个蒸发子流路41的出口端43中的制冷剂的温度，从而可以提高换热器10性能。Furthermore, in the first mode, the outlet end 43 of each evaporation sub-flow path 41 is disposed at one end of the second fin portion 22 close to the first fin portion 21. In the first mode, the heat exchange of the refrigerant in each evaporation sub-flow path is uneven, so that when the refrigerant flows to the outlet end of each evaporation sub-flow path, the outlet end temperature of each evaporation sub-flow path is uneven, and the refrigerant in the outlet end of some evaporation sub-flow paths is not completely volatilized, which is easy to cause backflow, thereby reducing the performance of the heat exchanger. In the first mode, the outlet end 43 of each evaporation sub-flow path 41 is arranged at one end of the second fin portion 22 close to the first fin portion 21, so that the outlet end 43 of each evaporation sub-flow path 41 is adjacent to the supercooling flow path 3, so as to facilitate the heat exchange between the refrigerant at the outlet end 43 of each evaporation sub-flow path 41 and the refrigerant in the supercooling flow path 3. The refrigerant in the outlet end 43 of the evaporation sub-flow path 41 with too low temperature can be heated, so that the liquid refrigerant therein continues to evaporate and reduce reflux. Therefore, the temperature of the refrigerant in the outlet end 43 of each evaporation sub-flow path 41 is balanced, thereby improving the performance of the heat exchanger 10.
另外，在第一模式，各个蒸发子流路41出口端43的液相的制冷剂换热效率高于各个蒸发子流路41出口端43的气相的制冷剂的换热效率，从而使得过冷流路3可以优先与带有液相制冷剂的蒸发子流路41的出口端43换热，从而进一步地可以减小制冷剂回流，同时气相制冷剂过热度不大，即气相制冷剂在换热之后温差不大，从而进一步地均衡了各个蒸发子流路41的出口端43中的制冷剂的温度，从而可以提高换热器10性能。In addition, in the first mode, the heat exchange efficiency of the liquid-phase refrigerant at the outlet end 43 of each evaporator sub-flow path 41 is higher than the heat exchange efficiency of the gas-phase refrigerant at the outlet end 43 of each evaporator sub-flow path 41, so that the supercooling flow path 3 can preferentially exchange heat with the outlet end 43 of the evaporator sub-flow path 41 with liquid-phase refrigerant, thereby further reducing the refrigerant reflux. At the same time, the superheat of the gas-phase refrigerant is not large, that is, the temperature difference of the gas-phase refrigerant after heat exchange is not large, thereby further balancing the temperature of the refrigerant in the outlet end 43 of each evaporator sub-flow path 41, thereby improving the performance of the heat exchanger 10.
同时，在第一模式，每个蒸发子流路41的出口端43均设于第二翅片部22的靠近第一翅片部21的一端,还可以便于各个蒸发子流路41的出口端43与气管500的连接，简化了连接结构，便于管路的布置和安装。At the same time, in the first mode, the outlet end 43 of each evaporation sub-flow path 41 is arranged at one end of the second fin portion 22 close to the first fin portion 21, which can also facilitate the connection between the outlet end 43 of each evaporation sub-flow path 41 and the air pipe 500, simplifying the connection structure and facilitating the layout and installation of the pipeline.
在本实用新型的一些实施例中，如图2-图4和图6-图8所示，在第一模式，每个蒸发子流路41的入口端42均设于第二翅片部22的背离第一翅片2的一端。由此，在第一模式，便于每个蒸发子流路41的入口端42与液管400连接，简化了连接结构，便于管路的布置和安装。In some embodiments of the present invention, as shown in FIGS. 2-4 and 6-8, in the first mode, the inlet end 42 of each evaporation sub-flow path 41 is disposed at an end of the second fin portion 22 away from the first fin 2. Thus, in the first mode, it is convenient to connect the inlet end 42 of each evaporation sub-flow path 41 with the liquid pipe 400, simplifying the connection structure and facilitating the arrangement and installation of the pipeline.
在第一模式，制冷剂在换热器10中的流动路径为：从液管400而来的制冷剂经过过冷流路3进行过冷，再通过各个蒸发子流路41入口端42进入各个的蒸发子流路41中进行换热，最后从各个的蒸发子流路41的出口端43流向气管500，流出换热器10。In the first mode, the flow path of the refrigerant in the heat exchanger 10 is as follows: the refrigerant from the liquid pipe 400 is supercooled through the supercooling flow path 3, and then enters each evaporation sub-flow path 41 through the inlet end 42 of each evaporation sub-flow path 41 for heat exchange, and finally flows from the outlet end 43 of each evaporation sub-flow path 41 to the gas pipe 500 and flows out of the heat exchanger 10.
在本实用新型的一些实施例中，如图2-图4和图6-图8所示，每个蒸发子流路41包括至少两排换热管1中的部分换热管1。可以理解的是，由于换热管1为在翅片2的宽度方向上间隔设置的多排，每个蒸发子流路41包括至少两排换热管1中的部分换热管1，从而使得每个蒸发子流路41中的制冷剂在在翅片2的宽度方向上换热均匀，从而使得换热器10换热均匀，提高换热器10效率。In some embodiments of the present invention, as shown in Fig. 2-Fig. 4 and Fig. 6-Fig. 8, each evaporation sub-flow path 41 includes part of the heat exchange tubes 1 in at least two rows of heat exchange tubes 1. It can be understood that, since the heat exchange tubes 1 are arranged in multiple rows at intervals in the width direction of the fin 2, each evaporation sub-flow path 41 includes part of the heat exchange tubes 1 in at least two rows of heat exchange tubes 1, so that the refrigerant in each evaporation sub-flow path 41 is evenly heat exchanged in the width direction of the fin 2, so that the heat exchange of the heat exchanger 10 is evenly heat exchanged, and the efficiency of the heat exchanger 10 is improved.
优选的，每个蒸发子流路41包括全排换热管1中的部分换热管1，从而进一步地使得每个蒸发子流路41中的制冷剂在在翅片2的宽度方向上换热均匀，从而使得换热器10换热均匀，提高换热器10效率。Preferably, each evaporation sub-flow path 41 includes part of the heat exchange tubes 1 in the entire row of heat exchange tubes 1, thereby further making the refrigerant in each evaporation sub-flow path 41 heat exchange uniformly in the width direction of the fin 2, thereby making the heat exchange of the heat exchanger 10 uniform and improving the efficiency of the heat exchanger 10.
例如在图2和图6所示的示例中，换热管1为在翅片2的宽度方向上间隔设置的两排，每个蒸发子流路41包括两排换热管1中的部分换热管1，例如在图3和图7所示的示例中，换热管1为在翅片2的宽度方向上间隔设置的三排，每个蒸发子流路41包括三排换热管1中的部分换热管1，例如在图4和图8所示的示例中，换热管1为在翅片2的宽度方向上间隔设置的四排，每个蒸发子流路41包括四排换热管1中的部分换热管1。For example, in the examples shown in Figures 2 and 6, the heat exchange tubes 1 are arranged in two rows at intervals in the width direction of the fin 2, and each evaporation sub-flow path 41 includes a portion of the heat exchange tubes 1 in the two rows of heat exchange tubes 1. For example, in the examples shown in Figures 3 and 7, the heat exchange tubes 1 are arranged in three rows at intervals in the width direction of the fin 2, and each evaporation sub-flow path 41 includes a portion of the heat exchange tubes 1 in the three rows of heat exchange tubes 1. For example, in the examples shown in Figures 4 and 8, the heat exchange tubes 1 are arranged in four rows at intervals in the width direction of the fin 2, and each evaporation sub-flow path 41 includes a portion of the heat exchange tubes 1 in the four rows of heat exchange tubes 1.
在本实用新型的一些实施例中，如图2-图4和图6-图8所示，每个蒸发子流路41包含的换热管1的排数相同。由此，进一步地使得每个蒸发子流路41中的制冷剂在在翅片2的宽度方向上换热均匀，从而使得换热器10换热均匀，提高换热器10效率。In some embodiments of the present invention, as shown in Figs. 2-4 and 6-8, each evaporation sub-flow path 41 includes the same number of rows of heat exchange tubes 1. Thus, the refrigerant in each evaporation sub-flow path 41 is further made to exchange heat evenly in the width direction of the fin 2, so that the heat exchange of the heat exchanger 10 is even, and the efficiency of the heat exchanger 10 is improved.
在本实用新型的一些实施例中，如图2-图4和图6-图8所示，在翅片2的长度方向上，多个蒸发子流路41从其中一排换热管1流向另一排换热管1的切换位置相同。In some embodiments of the present invention, as shown in FIGS. 2-4 and 6 - 8 , in the length direction of the fin 2 , the switching positions of the plurality of evaporation sub-flow paths 41 flowing from one row of heat exchange tubes 1 to another row of heat exchange tubes 1 are the same.
可以理解的是，在翅片2的长度方向上，当一个蒸发子流路41从其所在的一排换热管1流向另一排换热管1时，其余的蒸发子流路41从其所在的一排换热管1流向另一排换热管1，由此，可以使得每个蒸发子流路41中的制冷剂在在翅片2的长度方向上换热均匀，从而使得换热器10换热均匀，提高换热器10效率。It can be understood that, in the length direction of the fin 2, when one evaporation sub-flow path 41 flows from a row of heat exchange tubes 1 where it is located to another row of heat exchange tubes 1, the remaining evaporation sub-flow paths 41 flow from a row of heat exchange tubes 1 where they are located to another row of heat exchange tubes 1. As a result, the refrigerant in each evaporation sub-flow path 41 can be evenly heat exchanged in the length direction of the fin 2, thereby making the heat exchange of the heat exchanger 10 uniform and improving the efficiency of the heat exchanger 10.
例如在图2和图6所示的示例中，蒸发子流路41为两个，换热管1为沿翅片2宽度方向间隔开的两排，当外侧的蒸发子流路41从其所在的外排换热管1流向内排换热管1时，内侧的蒸发子流路41从其所在的内排换热管1流向外排换热管1。For example, in the examples shown in Figures 2 and 6, there are two evaporation sub-flow paths 41, and the heat exchange tubes 1 are in two rows spaced apart along the width direction of the fins 2. When the outer evaporation sub-flow path 41 flows from the outer row of heat exchange tubes 1 to the inner row of heat exchange tubes 1, the inner evaporation sub-flow path 41 flows from the inner row of heat exchange tubes 1 to the outer row of heat exchange tubes 1.
在本实用新型的一些实施例中，如图2-图4和图6-图8所示，第一模式下，在蒸发子流路41的入口端42至出口端43的方向上，同一蒸发子流路41中的多排换热管1依次串接。由此，使得换热管1连接方式简单，提高了生产效率。In some embodiments of the present invention, as shown in FIGS. 2-4 and 6-8, in the first mode, multiple rows of heat exchange tubes 1 in the same evaporation sub-flow path 41 are sequentially connected in series in the direction from the inlet end 42 to the outlet end 43 of the evaporation sub-flow path 41. Thus, the connection method of the heat exchange tubes 1 is simple, and the production efficiency is improved.
在本实用新型的一些实施例中，如图1-图8所示，过冷流路3和换热流路4之间设有节流阀5，节流阀5和多个蒸发子流路41通过分配器6连接。In some embodiments of the present invention, as shown in FIGS. 1 to 8 , a throttle valve 5 is provided between the subcooling flow path 3 and the heat exchange flow path 4 , and the throttle valve 5 and a plurality of evaporation sub-flow paths 41 are connected via a distributor 6 .
可以理解的是，在第一模式，节流阀5可以使得从过冷流路3而来的制冷剂可以节流降温，分配器6可以便于节流降温之后的制冷剂可以平均分配至各个蒸发子流路41中，从而可以使得换热器10换热均匀，提高换热效率。It can be understood that in the first mode, the throttle valve 5 can throttle and cool the refrigerant coming from the subcooling flow path 3, and the distributor 6 can facilitate the even distribution of the refrigerant after throttling and cooling to each evaporation sub-flow path 41, so that the heat exchanger 10 can exchange heat evenly and improve the heat exchange efficiency.
在第一模式，制冷剂在换热器10中的流路为：制冷剂从液管400流向过冷流路3进行过冷，过冷后的制冷剂经过节流阀5的节流降温作用，再通过分配器6进入各个蒸发子流路41中，最后从气管500流出。In the first mode, the flow path of the refrigerant in the heat exchanger 10 is: the refrigerant flows from the liquid pipe 400 to the subcooling flow path 3 for subcooling, the supercooled refrigerant passes through the throttling and cooling effect of the throttle valve 5, then enters each evaporation sub-flow path 41 through the distributor 6, and finally flows out from the gas pipe 500.
在本实用新型的一些实施例中，如图3、图4、图7和图8所示，翅片2为矩形，翅片2的四个拐角中的至少一个拐角处具有缺口23。可以理解的是，翅片2的四个拐角中的至少一个拐角处具有缺口23可以减少拐角处的面积，从而减小了翅片2与空调室内机100壁面的安装干扰以及相邻两个换热器10的翅片2之间的安装干扰，保证了翅片2的长度，从而保证了换热器10中沿翅片2长度方向的换热管1有足够的数量保证换热效率。同时，能够增大换热器10的进风口面积，减小换热器10的倾角，从而可以降低空调室内机100内的风机的功率。In some embodiments of the utility model, as shown in FIG. 3, FIG. 4, FIG. 7 and FIG. 8, the fin 2 is rectangular, and at least one of the four corners of the fin 2 has a notch 23. It can be understood that the notch 23 at at least one of the four corners of the fin 2 can reduce the area of the corner, thereby reducing the installation interference between the fin 2 and the wall of the air conditioner indoor unit 100 and the installation interference between the fins 2 of two adjacent heat exchangers 10, ensuring the length of the fin 2, thereby ensuring that there are enough heat exchange tubes 1 in the heat exchanger 10 along the length direction of the fin 2 to ensure heat exchange efficiency. At the same time, the air inlet area of the heat exchanger 10 can be increased, and the inclination angle of the heat exchanger 10 can be reduced, so that the power of the fan in the air conditioner indoor unit 100 can be reduced.
例如在图3、图4、图7和图8所示的示例中，翅片2的四个拐角中的四个拐角处均具有缺口23，但是本实用新型并不限于此，还可以是翅片2的四个拐角中的三个、两个或一个拐角处具有缺口23。For example, in the examples shown in Figures 3, 4, 7 and 8, four of the four corners of the fin 2 have a notch 23, but the utility model is not limited to this. Three, two or one of the four corners of the fin 2 may also have a notch 23.
下面参考附图描述根据本实用新型实施例的空调室内机100。The air conditioner indoor unit 100 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.
如图1-图8所示，根据本实用新型实施例的空调室内机100，包括上述的换热器10。As shown in FIG. 1 to FIG. 8 , an air-conditioning indoor unit 100 according to an embodiment of the present invention includes the heat exchanger 10 described above.
具体地，参考图1-图8，换热器10为多个，多个过冷流路3连接，多个换热流路4并联连接。可以理解的是，多个换热流路4并联连接，从而使得制冷剂可以同时在多个换热流路4中流动，提高了制冷剂的流动效率，从而提高了空调室内机100的换热效率。而多个过冷流路3之间可以串联也可以并联，从而增加了连接方式，可以满足不同的结构需求。Specifically, referring to Figures 1 to 8, there are multiple heat exchangers 10, multiple subcooling flow paths 3 are connected, and multiple heat exchange flow paths 4 are connected in parallel. It can be understood that multiple heat exchange flow paths 4 are connected in parallel, so that the refrigerant can flow in multiple heat exchange flow paths 4 at the same time, improving the flow efficiency of the refrigerant, thereby improving the heat exchange efficiency of the air conditioner indoor unit 100. Multiple subcooling flow paths 3 can be connected in series or in parallel, thereby increasing the connection mode and meeting different structural requirements.
例如在图1-图8所示的示例中，换热器10为四个，换热流路4为四个，过冷流路3为四个，四个过冷流路3串联，但是本实用新型并不限于此，换热器10、换热流路4和过冷流路3可以为更多个或更少个，如2个、3个、5个或6个等。For instance, in the examples shown in FIGS. 1 to 8 , there are four heat exchangers 10, four heat exchange paths 4, and four subcooling paths 3, and the four subcooling paths 3 are connected in series. However, the present invention is not limited thereto, and the number of heat exchangers 10, heat exchange paths 4, and subcooling paths 3 may be more or less, such as 2, 3, 5, or 6, etc.
根据本实用新型实施例的空调室内机100，通过设置上述的换热器10，过冷管11穿设于第一翅片部21上，蒸发管12穿设于第二翅片部22上，第一翅片部21上的过冷管11连接后形成过冷流路3，第二翅片部22上的蒸发管12连接后形成换热流路4，在第一模式，制冷剂由过冷流路3流向换热流路4，换热流路4的出口端43位于第二翅片部22的靠近第一翅片部21的一端。从而使得换热流路4的出口端43与过冷流路3相邻，从而便于换热流路4的出口端43的制冷剂与过冷流路3流中的制冷剂换热，从而在第一模式，便于出口端43的气液两相制冷剂转变为气相制冷剂，减少制冷剂回流，从而可以提高换热器10的换热效率。According to the air conditioner indoor unit 100 of the embodiment of the utility model, by setting the above-mentioned heat exchanger 10, the subcooling tube 11 is passed through the first fin part 21, the evaporation tube 12 is passed through the second fin part 22, the subcooling tube 11 on the first fin part 21 is connected to form a subcooling flow path 3, and the evaporation tube 12 on the second fin part 22 is connected to form a heat exchange flow path 4. In the first mode, the refrigerant flows from the subcooling flow path 3 to the heat exchange flow path 4, and the outlet end 43 of the heat exchange flow path 4 is located at one end of the second fin part 22 close to the first fin part 21. Therefore, the outlet end 43 of the heat exchange flow path 4 is adjacent to the subcooling flow path 3, so that the refrigerant at the outlet end 43 of the heat exchange flow path 4 is convenient for heat exchange with the refrigerant in the subcooling flow path 3, so that in the first mode, the gas-liquid two-phase refrigerant at the outlet end 43 is convenient for conversion into gas-phase refrigerant, reducing refrigerant reflux, thereby improving the heat exchange efficiency of the heat exchanger 10.
在本实用新型的一些实施例中，如图1-图8所示，多个换热器10沿直线排布，且多个换热器10中任意相邻的两个换热器10的翅片2的长度方向互成角度，任意相邻的两个换热器10沿翅片2长度方向的一端连接，在换热器10的数量大于等于三个时，任意相邻的三个换热器10中位于中间的换热器10长度方向的两端分别与另外两个换热器10长度方向的一端连接。In some embodiments of the present invention, as shown in Figures 1 to 8, a plurality of heat exchangers 10 are arranged in a straight line, and the length directions of the fins 2 of any two adjacent heat exchangers 10 among the plurality of heat exchangers 10 form an angle with each other, and any two adjacent heat exchangers 10 are connected at one end along the length direction of the fin 2. When the number of the heat exchangers 10 is greater than or equal to three, the two ends of the length direction of the middle heat exchanger 10 among any three adjacent heat exchangers 10 are respectively connected to one end of the length direction of the other two heat exchangers 10.
可以理解的是，多个换热器10中任意相邻的两个换热器10的翅片2的长度方向互成角度，从而使得空调室内机100的整体高度减小，有利于优化空调室内机100的布局，同时，多个换热器10中任意相邻的两个换热器10的翅片2的长度方向互成角度可以使得多个换热器10之间形成不同的形状，从而有利于适应空调室内机100内部空间，有利于空调室内机100的安装。It can be understood that the length directions of the fins 2 of any two adjacent heat exchangers 10 among the multiple heat exchangers 10 are at an angle to each other, so that the overall height of the air-conditioning indoor unit 100 is reduced, which is beneficial to optimizing the layout of the air-conditioning indoor unit 100. At the same time, the length directions of the fins 2 of any two adjacent heat exchangers 10 among the multiple heat exchangers 10 are at an angle to each other, so that different shapes can be formed between the multiple heat exchangers 10, which is beneficial to adapt to the internal space of the air-conditioning indoor unit 100 and the installation of the air-conditioning indoor unit 100.
例如在图1-图8所示的示例中，换热器10为四个，四个换热器10为M型排布，即沿竖直方向，相邻两个换热器10倾斜方向相反，中间两个换热器10的下端相互连接，中间两个换热器10的上端分别与另外两个换热器10的上端连接，但是本实用新型并不限于此，换热器10可以为更多个或更少个，多个换热器10可以为N型排布，也可以为W型排布，也可以为V型排布等。For instance, in the examples shown in FIGS. 1 to 8 , there are four heat exchangers 10, and the four heat exchangers 10 are arranged in an M shape, that is, along the vertical direction, two adjacent heat exchangers 10 are inclined in opposite directions, the lower ends of the two middle heat exchangers 10 are connected to each other, and the upper ends of the two middle heat exchangers 10 are respectively connected to the upper ends of the other two heat exchangers 10, but the utility model is not limited thereto, and the number of the heat exchangers 10 may be more or less, and the multiple heat exchangers 10 may be arranged in an N shape, a W shape, a V shape, etc.
在本实用新型的一些实施例中，如图1-图8所示，多个换热器10的过冷流路3位于与多个换热器10排布方向垂直的方向的同一端。可以理解的是，过冷流路3的一端需要与液管400连接，另一端与分配器6连接，多个换热器10的过冷流路3位于与多个换热器10排布方向垂直的方向的同一端，可以便于多个换热器10的过冷流路3与液管400和分配器6连接，简化了连接结构，便于管路的布置和安装。In some embodiments of the present invention, as shown in Fig. 1 to Fig. 8, the subcooling flow paths 3 of the multiple heat exchangers 10 are located at the same end in a direction perpendicular to the arrangement direction of the multiple heat exchangers 10. It can be understood that one end of the subcooling flow path 3 needs to be connected to the liquid pipe 400, and the other end is connected to the distributor 6. The subcooling flow paths 3 of the multiple heat exchangers 10 are located at the same end in a direction perpendicular to the arrangement direction of the multiple heat exchangers 10, which can facilitate the connection of the subcooling flow paths 3 of the multiple heat exchangers 10 with the liquid pipe 400 and the distributor 6, simplify the connection structure, and facilitate the arrangement and installation of the pipeline.
在本实用新型的一些实施例中，如图2-图4和图6-图8所示，多个换热器10的翅片2、换热管1、过冷流路3和换热流路4相同。由此，使得空调室内机100换热均匀，同时多个换热器10的翅片2、换热管1、过冷流路3和换热流路4相同，也有利于提高生产效率，简化空调室内机100的结构。In some embodiments of the present invention, as shown in Fig. 2-Fig. 4 and Fig. 6-Fig. 8, the fins 2, heat exchange tubes 1, subcooling flow paths 3 and heat exchange flow paths 4 of multiple heat exchangers 10 are the same. Thus, the heat exchange of the air conditioner indoor unit 100 is uniform, and the fins 2, heat exchange tubes 1, subcooling flow paths 3 and heat exchange flow paths 4 of multiple heat exchangers 10 are the same, which is also conducive to improving production efficiency and simplifying the structure of the air conditioner indoor unit 100.
在本实用新型的一些实施例中，如图1-图8所示，空调室内机100还包括：接水盘200，接水盘200位于换热器10的下方，翅片2的长度方向沿竖直方向延伸或与竖直方向之间的夹角为锐角。In some embodiments of the present invention, as shown in Figures 1 to 8, the air conditioner indoor unit 100 further includes: a water receiving tray 200, the water receiving tray 200 is located below the heat exchanger 10, and the length direction of the fin 2 extends along the vertical direction or the angle between it and the vertical direction is an acute angle.
可以理解的是，接水盘200位于换热器10的下方，接水盘200用于容纳换热器10上的冷凝水，换热器10表面的冷凝水可以沿着翅片2的长度方向从上到下流至接水盘200中，翅片2的长度方向沿竖直方向延伸或与竖直方向之间的夹角为锐角，从而可以使得冷凝水可以沿着翅片2的长度方向从上到下流至接水盘200中。It can be understood that the water receiving tray 200 is located below the heat exchanger 10. The water receiving tray 200 is used to accommodate condensed water on the heat exchanger 10. The condensed water on the surface of the heat exchanger 10 can flow from top to bottom along the length direction of the fin 2 to the water receiving tray 200. The length direction of the fin 2 extends along the vertical direction or the angle between it and the vertical direction is an acute angle, so that the condensed water can flow from top to bottom along the length direction of the fin 2 to the water receiving tray 200.
进一步地，如图9和图10所示，过冷流路3位于换热流路4的上方或下方，从而使得过冷流路3和换热流路4在换热器10或空调室内机100中有不同的布置形式，从而满足不同结构的空调室内机100的需求。例如如图1-图4和9所示，过冷流路3位于换热流路4的上方，此时第一翅片部21相对于第二翅片部22靠近换热器10的上端设置，换热流路4的入口端42位于第二翅片部22的下端设置，换热流路4的出口端43位于第二翅片部22的上端设置。当过冷流路3位于换热流路4的上方时，制冷剂在换热流路4中的流向为自下而上流，从而便于换热流路4出口端43的制冷剂与过冷流路3中的制冷剂进行换热。Further, as shown in FIG9 and FIG10, the subcooling flow path 3 is located above or below the heat exchange flow path 4, so that the subcooling flow path 3 and the heat exchange flow path 4 have different arrangements in the heat exchanger 10 or the air conditioner indoor unit 100, thereby meeting the needs of the air conditioner indoor units 100 of different structures. For example, as shown in FIG1-FIG4 and FIG9, the subcooling flow path 3 is located above the heat exchange flow path 4, at this time, the first fin portion 21 is arranged near the upper end of the heat exchanger 10 relative to the second fin portion 22, the inlet end 42 of the heat exchange flow path 4 is arranged at the lower end of the second fin portion 22, and the outlet end 43 of the heat exchange flow path 4 is arranged at the upper end of the second fin portion 22. When the subcooling flow path 3 is located above the heat exchange flow path 4, the refrigerant in the heat exchange flow path 4 flows from bottom to top, so that the refrigerant at the outlet end 43 of the heat exchange flow path 4 is convenient for heat exchange with the refrigerant in the subcooling flow path 3.
如图5-图8和图10所示，过冷流路3位于换热流路4的下方，此时换热流路4的入口端42位于第二翅片部22的上端设置，换热流路4的出口端43位于第二翅片部22的下端设置。当过冷流路3位于换热流路4的下方时，制冷剂在换热流路4中的流向为自上而下流，从而便于换热流路4出口端43的制冷剂与过冷流路3中的制冷剂进行换热。As shown in Fig. 5 to Fig. 8 and Fig. 10, the subcooling flow path 3 is located below the heat exchange flow path 4, and the inlet end 42 of the heat exchange flow path 4 is located at the upper end of the second fin portion 22, and the outlet end 43 of the heat exchange flow path 4 is located at the lower end of the second fin portion 22. When the subcooling flow path 3 is located below the heat exchange flow path 4, the refrigerant flows from top to bottom in the heat exchange flow path 4, so that the refrigerant at the outlet end 43 of the heat exchange flow path 4 and the refrigerant in the subcooling flow path 3 can exchange heat.
在本实用新型的一些实施例中，如图1-图8所示，翅片2的下端位于接水盘200内，接水盘200的内壁与换热器10之间的距离小于1cm，例如0.8cm、0.5cm、0.3cm或0.1cm等。可以理解的是，接水盘200的内壁与换热器10之间的距离小于1cm，可以使得接水盘200将换热器10的上端包裹住，由此，当过冷管11位于换热器10的下端时，使得接水盘200可以将过冷管11完全遮蔽，从而避免过冷流路3中的制冷剂直接对空气加热，从而提高过冷效果。In some embodiments of the present invention, as shown in FIGS. 1 to 8 , the lower end of the fin 2 is located in the water receiving tray 200, and the distance between the inner wall of the water receiving tray 200 and the heat exchanger 10 is less than 1 cm, such as 0.8 cm, 0.5 cm, 0.3 cm or 0.1 cm, etc. It can be understood that the distance between the inner wall of the water receiving tray 200 and the heat exchanger 10 is less than 1 cm, so that the water receiving tray 200 can wrap the upper end of the heat exchanger 10, so that when the subcooling tube 11 is located at the lower end of the heat exchanger 10, the water receiving tray 200 can completely shield the subcooling tube 11, thereby preventing the refrigerant in the subcooling flow path 3 from directly heating the air, thereby improving the subcooling effect.
进一步地，如图1-图8所示，接水盘200的内壁与换热器10之间间隔开，从而避免接水盘200和换热器10之间相互传热，影响换热器10工作，从而提高了换热器10工作效率。Furthermore, as shown in FIGS. 1-8 , the inner wall of the water receiving pan 200 is spaced apart from the heat exchanger 10 , thereby preventing heat transfer between the water receiving pan 200 and the heat exchanger 10 and affecting the operation of the heat exchanger 10 , thereby improving the operating efficiency of the heat exchanger 10 .
另外，当过冷流路3位于换热流路4的下方时，此时过冷流路3位于换热器10的下端，由于翅片2的下端位于接水盘200内，从而使得过冷流路3位于接水盘200内，从而使得接水盘200内的冷凝水可以与过冷流路3中的制冷剂换热，从而进一步地提高了过冷效果，进一步地提高了换热器10的换热效率，提高了空调室内机100的工作效率。In addition, when the subcooling flow path 3 is located below the heat exchange flow path 4, the subcooling flow path 3 is located at the lower end of the heat exchanger 10. Since the lower end of the fin 2 is located in the water receiving pan 200, the subcooling flow path 3 is located in the water receiving pan 200, so that the condensed water in the water receiving pan 200 can exchange heat with the refrigerant in the subcooling flow path 3, thereby further improving the subcooling effect, further improving the heat exchange efficiency of the heat exchanger 10, and improving the working efficiency of the air-conditioning indoor unit 100.
当过冷流路3位于换热流路4的下方时，此时过冷流路3位于换热器10的下端，换热流路4的出口端位于下方，从而使得接水盘200内的冷凝水可以与换热流路4的出口端中的制冷剂换热，由于接水盘200内的冷凝水温度高于各换热流路4和各蒸发子流路41的出口端43中的气液两相制冷剂，从而使得冷凝水可以对出口端43中的气液两相制冷剂加热，从而便于出口端43中的气液两相制冷剂中的液相制冷剂继续挥发，从而减小制冷剂回流。When the supercooling flow path 3 is located below the heat exchange flow path 4, the supercooling flow path 3 is located at the lower end of the heat exchanger 10, and the outlet end of the heat exchange flow path 4 is located below, so that the condensed water in the water receiving tray 200 can exchange heat with the refrigerant in the outlet end of the heat exchange flow path 4. Since the temperature of the condensed water in the water receiving tray 200 is higher than the gas-liquid two-phase refrigerant in the outlet end 43 of each heat exchange flow path 4 and each evaporation sub-flow path 41, the condensed water can heat the gas-liquid two-phase refrigerant in the outlet end 43, thereby facilitating the continued volatilization of the liquid refrigerant in the gas-liquid two-phase refrigerant in the outlet end 43, thereby reducing the refrigerant reflux.
同时，由于接水盘200内的冷凝水温度低于出口端43中的气相制冷剂，从而可以对出口端43中的气相制冷剂进行降温，避免出口端43中的气相制冷剂提前过热，从而进一步地使得各换热流路4和各蒸发子流路41的出口端43中的制冷剂温度均匀，从而提高换热器的换热效率。At the same time, since the temperature of the condensed water in the water receiving pan 200 is lower than the gas-phase refrigerant in the outlet end 43, the gas-phase refrigerant in the outlet end 43 can be cooled to avoid premature overheating of the gas-phase refrigerant in the outlet end 43, thereby further making the refrigerant temperature in the outlet end 43 of each heat exchange flow path 4 and each evaporation sub-flow path 41 uniform, thereby improving the heat exchange efficiency of the heat exchanger.
在本实用新型的一些实施例中，如图1-图8所示，换热器10与水平面的夹角大于45°，例如夹角可以为45°、48°、50°、53°、55°、57°、60°、65°、70°、73°、78°、80°或83°。从而可以使冷凝水沿着换热器10的长度方向流向接水盘200，接住换热器10上流下的冷凝水，避免冷凝水滴落到空调室内机100的风道内，从而避免空调室内机100出现滴水的情况，降低空调室内机100内的部件出现短路的情况，保障空调室内机100的安全性。In some embodiments of the present invention, as shown in FIG. 1 to FIG. 8 , the angle between the heat exchanger 10 and the horizontal plane is greater than 45°, for example, the angle may be 45°, 48°, 50°, 53°, 55°, 57°, 60°, 65°, 70°, 73°, 78°, 80° or 83°. Thus, the condensed water can flow to the water receiving pan 200 along the length direction of the heat exchanger 10, and the condensed water flowing down the heat exchanger 10 can be received to prevent the condensed water from dripping into the air duct of the air conditioner indoor unit 100, thereby preventing the air conditioner indoor unit 100 from dripping, reducing the short circuit of the components in the air conditioner indoor unit 100, and ensuring the safety of the air conditioner indoor unit 100.
在本实用新型的一些实施例中，如图1-图8所示，换热器10的上端包裹有顶盖板300，顶盖板300的侧壁与换热器10之间的距离小于1cm，例如0.8cm、0.5cm、0.3cm或0.1cm等。由此，可以使得顶盖板300将换热器10的上端包裹住，由此，当过冷管11位于换热器10的上端时，使得顶盖板300可以将过冷管11完全遮蔽，从而避免过冷流路3中的制冷剂直接对空气加热，提高过冷效果。In some embodiments of the present invention, as shown in FIGS. 1 to 8 , the upper end of the heat exchanger 10 is wrapped with a top cover plate 300, and the distance between the side wall of the top cover plate 300 and the heat exchanger 10 is less than 1 cm, such as 0.8 cm, 0.5 cm, 0.3 cm or 0.1 cm, etc. Thus, the top cover plate 300 can wrap the upper end of the heat exchanger 10, so that when the subcooling tube 11 is located at the upper end of the heat exchanger 10, the top cover plate 300 can completely shield the subcooling tube 11, thereby preventing the refrigerant in the subcooling flow path 3 from directly heating the air and improving the subcooling effect.
进一步地，如图1-图8所示，顶盖板300的内壁与换热器10之间间隔开，从而避免顶盖板300和换热器10之间相互传热，影响换热器10工作，从而提高了换热器10工作效率。Furthermore, as shown in FIGS. 1-8 , the inner wall of the top cover plate 300 is spaced apart from the heat exchanger 10 , thereby preventing heat transfer between the top cover plate 300 and the heat exchanger 10 and affecting the operation of the heat exchanger 10 , thereby improving the operating efficiency of the heat exchanger 10 .
在本实用新型的一些实施例中，如图1-图4所示，空调室内机100还包括：风机600，风机600与换热器10在上下方向上排布，翅片2的长度方向与上下方向之间的夹角为锐角，换热流路3内的制冷剂流向与翅片2的长度方向相同；在第一模式，换热流路3内的制冷剂流向与风机600形成的风向相同，沿风向的方向上，风机600形成的风速逐渐增大。In some embodiments of the present invention, as shown in Figures 1 to 4, the air-conditioning indoor unit 100 also includes: a fan 600, which is arranged in the up-down direction with the heat exchanger 10, and the angle between the length direction of the fin 2 and the up-down direction is an acute angle, and the refrigerant flow direction in the heat exchange flow path 3 is the same as the length direction of the fin 2; in the first mode, the refrigerant flow direction in the heat exchange flow path 3 is the same as the wind direction formed by the fan 600, and the wind speed formed by the fan 600 gradually increases along the wind direction.
风机600用于加快换热器10中的空气流动速度，其中，在本实用新型中，由于越靠近风机600，流速越大，换热流路3内的制冷剂流向与风机600形成的风向相同，则换热流路3内的制冷剂由换热器10的背离风机600的一端流向换热器10的靠近风机600的一端。另外，换热流路3内的制冷剂流向与风机600形成的风向可以形成有夹角，但夹角小于90度。The fan 600 is used to speed up the air flow speed in the heat exchanger 10. In the present invention, since the closer to the fan 600, the greater the flow speed, the refrigerant flow direction in the heat exchange flow path 3 is the same as the wind direction formed by the fan 600, and the refrigerant in the heat exchange flow path 3 flows from the end of the heat exchanger 10 away from the fan 600 to the end of the heat exchanger 10 close to the fan 600. In addition, the refrigerant flow direction in the heat exchange flow path 3 and the wind direction formed by the fan 600 may form an angle, but the angle is less than 90 degrees.
可以理解的是，翅片2为沿翅片2厚度方向间隔开的多个，换热管1穿设于多个翅片2中，在第一模式(制冷模式)，换热流路3为蒸发流路，换热流路3内的制冷剂由换热器10的背离风机600的一端流向换热器10的靠近风机600的一端，随着制冷剂在换热流路3内不断蒸发，在换热器10的背离风机600的一端至换热器10的靠近风机600的一端方向上，制冷剂干度逐渐变大，制冷剂的换热系数呈现逐渐增大的趋势，同时，由于越靠近风机600，流速越大，空气换热系数越高，由此，在换热器10的背离风机600的一端至换热器10的靠近风机600的一端方向上，即在风向方向上，空气换热系数也逐渐增大，从而使得在制冷模式，在换热器10的背离风机600的一端至换热器10的靠近风机600的一端方向上，即在风向方向上，制冷剂的换热系数的变化趋势与空气的换热系数变化趋势相适应，从而可以提高换热器10的在制冷时的换热效率。It can be understood that the fins 2 are multiple and spaced apart in the thickness direction of the fins 2, and the heat exchange tubes 1 are arranged in the multiple fins 2. In the first mode (cooling mode), the heat exchange flow path 3 is an evaporation flow path, and the refrigerant in the heat exchange flow path 3 flows from the end of the heat exchanger 10 away from the fan 600 to the end of the heat exchanger 10 close to the fan 600. As the refrigerant continues to evaporate in the heat exchange flow path 3, the refrigerant dryness gradually increases in the direction from the end of the heat exchanger 10 away from the fan 600 to the end of the heat exchanger 10 close to the fan 600, and the heat transfer coefficient of the refrigerant shows a trend of gradually increasing. At the same time, Since the closer to the fan 600, the greater the flow rate, the higher the air heat exchange coefficient, therefore, the air heat exchange coefficient gradually increases in the direction from the end of the heat exchanger 10 away from the fan 600 to the end of the heat exchanger 10 close to the fan 600, that is, in the wind direction. As a result, in the cooling mode, in the direction from the end of the heat exchanger 10 away from the fan 600 to the end of the heat exchanger 10 close to the fan 600, that is, in the wind direction, the change trend of the heat exchange coefficient of the refrigerant is consistent with the change trend of the heat exchange coefficient of the air, thereby improving the heat exchange efficiency of the heat exchanger 10 during cooling.
在本实用新型的一些实施例中，如图1-图4所示，在第二模式，换热流路3内的制冷剂流向与风机600形成的风向相反，沿风向的方向上，风机600形成的风速逐渐增大。In some embodiments of the present invention, as shown in FIGS. 1 to 4 , in the second mode, the refrigerant flow direction in the heat exchange flow path 3 is opposite to the wind direction formed by the fan 600 , and the wind speed formed by the fan 600 gradually increases along the wind direction.
可以理解的是，在第二模式(制热模式)，本实用新型中的风向方向也为在换热器10的背离风机600的一端至换热器10的靠近风机600的一端方向上。在制热模式，换热流路3为冷凝流路，换热流路3的入口端31为冷凝流路的出口，换热流路3的出口端32为冷凝流路的入口，从而在制热模式，冷凝流路内的制冷剂由换热器10的靠近风机600的一端流向换热器10的背离风机600的一端，随着制冷剂在冷凝流路内不断冷凝，在换热器10的靠近风机600的一端至换热器10的背离风机600的一端方向上，即风向方向，制冷剂干度逐渐减小，制冷剂的换热系数呈现逐渐减小的趋势，换而言之，在换热器10的远离风机600的一端至换热器10的靠近风机600的一端方向上，即风向方向，制冷剂干度逐渐增大，制冷剂的换热系数呈现逐渐增大的趋势，同时，在换热器10的背离风机600的一端至换热器10的靠近风机600的一端方向上，即在风向方向上，空气换热系数也逐渐增大，从而使得在制热模式，在换热器10的背离风机600的一端至换热器10的靠近风机600的一端方向上，制冷剂的换热系数的变化趋势与空气的换热系数变化趋势也可以相适应，从而可以提高换热器10的在制热时的换热效率。It can be understood that in the second mode (heating mode), the wind direction in the utility model is also in the direction from the end of the heat exchanger 10 away from the fan 600 to the end of the heat exchanger 10 close to the fan 600. In the heating mode, the heat exchange flow path 3 is a condensation flow path, the inlet end 31 of the heat exchange flow path 3 is the outlet of the condensation flow path, and the outlet end 32 of the heat exchange flow path 3 is the inlet of the condensation flow path. Therefore, in the heating mode, the refrigerant in the condensation flow path flows from the end of the heat exchanger 10 close to the fan 600 to the end of the heat exchanger 10 away from the fan 600. As the refrigerant continues to condense in the condensation flow path, the refrigerant dryness gradually decreases in the direction from the end of the heat exchanger 10 close to the fan 600 to the end of the heat exchanger 10 away from the fan 600, that is, the wind direction, and the heat transfer coefficient of the refrigerant shows a trend of gradually decreasing. In other words, at the end of the heat exchanger 10 away from the fan 600, the refrigerant dryness gradually decreases. The heat transfer coefficient of the refrigerant shows a trend of gradually decreasing. In other words, at the end of the heat exchanger 10 away from the fan 600, the refrigerant dryness gradually decreases. In the direction from the end of the heat exchanger 10 away from the fan 600 to the end of the heat exchanger 10 close to the fan 600, that is, in the wind direction, the dryness of the refrigerant gradually increases, and the heat transfer coefficient of the refrigerant shows a trend of gradually increasing. At the same time, in the direction from the end of the heat exchanger 10 away from the fan 600 to the end of the heat exchanger 10 close to the fan 600, that is, in the wind direction, the heat transfer coefficient of the air also gradually increases. As a result, in the heating mode, in the direction from the end of the heat exchanger 10 away from the fan 600 to the end of the heat exchanger 10 close to the fan 600, the change trend of the heat transfer coefficient of the refrigerant can also be adapted to the change trend of the heat transfer coefficient of the air, thereby improving the heat exchange efficiency of the heat exchanger 10 during heating.
由此，在第一模式和第二模式时，在换热器10的远离风机600的一端至换热器10的靠近风机600的一端方向上，即在风向方向上，制冷剂的换热系数与空气的换热系数均逐渐增大，从而可以使得制冷剂的换热系数的变化趋势与空气的换热系数变化趋势相适应，从而可以提高换热器10的换热效率。Therefore, in the first mode and the second mode, in the direction from the end of the heat exchanger 10 away from the fan 600 to the end of the heat exchanger 10 close to the fan 600, that is, in the wind direction, the heat transfer coefficient of the refrigerant and the heat transfer coefficient of the air gradually increase, so that the changing trend of the heat transfer coefficient of the refrigerant can be adapted to the changing trend of the heat transfer coefficient of the air, thereby improving the heat exchange efficiency of the heat exchanger 10.
在本实用新型的一些实施例中，如图1所示，空调室内机100包括换热风道，换热风道形成有安装腔20和与安装腔20连通的换热进口(未示出)和换热出口(未示出)，风机600设置在靠近换热出口的一端，换热器10设置在安装腔20内，换热器10的一端位于换热进口的一侧，换热器10的另一端朝换热出口的方向延伸且朝换热进口的一侧倾斜。In some embodiments of the present invention, as shown in Figure 1, the air conditioner indoor unit 100 includes a heat exchange air duct, the heat exchange air duct is formed with an installation cavity 20 and a heat exchange inlet (not shown) and a heat exchange outlet (not shown) connected to the installation cavity 20, the fan 600 is arranged at one end close to the heat exchange outlet, the heat exchanger 10 is arranged in the installation cavity 20, one end of the heat exchanger 10 is located on one side of the heat exchange inlet, and the other end of the heat exchanger 10 extends in the direction of the heat exchange outlet and is inclined toward one side of the heat exchange inlet.
由此，换热器10中，越靠近换热出口的部分经过的风量越大，提高了在换热出口处的制冷剂换热量，同时越靠近换热出口，空气的换热系数越大，制冷剂干度也越大，从而进一步地使得制冷剂的换热系数的变化趋势与空气的换热系数变化趋势相适应，从而可以进一步地提高换热器10的换热效率。Therefore, in the heat exchanger 10, the air volume passing through the part closer to the heat exchange outlet is larger, thereby increasing the refrigerant heat exchange amount at the heat exchange outlet. At the same time, the closer to the heat exchange outlet, the greater the heat transfer coefficient of the air and the greater the dryness of the refrigerant, thereby further making the changing trend of the heat transfer coefficient of the refrigerant adapt to the changing trend of the heat transfer coefficient of the air, thereby further improving the heat exchange efficiency of the heat exchanger 10.
