背景技术Background technique
变频模块是变频空调器中的重要元器件，变频模块的散热问题与空调器的可靠性密切相关。压缩机频率越高，变频模块发热越多，其次，芯片设计上更加紧凑，元器件的密度不断增加，且元器件的体积也趋于微小化，导致变频模块的散热越来越困难。The inverter module is an important component in the inverter air conditioner, and the heat dissipation problem of the inverter module is closely related to the reliability of the air conditioner. The higher the compressor frequency, the more heat the inverter module generates. Secondly, the chip design is more compact, the density of components continues to increase, and the volume of components tends to be miniaturized, making it more and more difficult to dissipate heat from the inverter module.
目前，空调器室外机变频模块的散热一般采用挤压型材散热器，通过改变肋片的面积和形状进行散热优化。但是，现有的散热器仍无法将变频模块产生的热量及时散发出去，尤其在高环温下，变频模块的温度急剧升高，而散热器的散热能力有限，严重影响了空调器的可靠性。At present, the heat dissipation of the frequency conversion module of the outdoor unit of the air conditioner generally adopts an extruded radiator, and the heat dissipation is optimized by changing the area and shape of the fins. However, the existing radiator is still unable to dissipate the heat generated by the frequency conversion module in time, especially under high ambient temperature, the temperature of the frequency conversion module rises sharply, and the heat dissipation capacity of the radiator is limited, which seriously affects the reliability of the air conditioner .

The working fluid can transfer the heat of the first heat dissipation module 1 to the second heat dissipation module 2 , so that the first heat dissipation module 1 and the second heat dissipation module 2 can perform heat dissipation functions at the same time, thereby improving the heat dissipation capability of the radiator.
本发明实施例对待散热物体不作具体限制，例如，可以是空调室外机中的变频模块6。空调室外机的变频模块6设置有多个大功率元器件，随着空调器外机小型化，以及空调器功能多样化的需要，空调器外机电控模块的芯片设计上更加紧凑，元器件的密度不断增加，且元器件的体积也趋于微小化。因此，大功率元器件发热功耗越来越大，热流密度急剧升高。为保证空调器外机电控的安全性和可靠性，变频模块6的散热性能至关重要。现有的对空调器室外机的变频模块6的散热器的改进方法一般是优化散热器的本体，例如，增加肋片高度、肋片数量等方法提高散热器的散热面积，但是，由于空调器室外机的空间有限，散热器本体的优化空间很小，进而使得散热器的散热性能提升有限。本发明实施例提供了一种具有两个散热模块的高散热能力的散热器，可及时将变频模块6产生的热量进行散失，提高了变频模块6运行的可靠性和稳定性。The embodiment of the present invention does not specifically limit the object to be radiated, for example, it may be the frequency conversion module 6 in the outdoor unit of the air conditioner. The frequency conversion module 6 of the outdoor unit of the air conditioner is provided with a number of high-power components. With the miniaturization of the outdoor unit of the air conditioner and the need for diversified functions of the air conditioner, the chip design of the control module of the outdoor unit of the air conditioner is more compact, and the components The density of the components continues to increase, and the volume of the components tends to be miniaturized. Therefore, the heating power consumption of high-power components is increasing, and the heat flux density is rising sharply. In order to ensure the safety and reliability of the external electrical control of the air conditioner, the heat dissipation performance of the frequency conversion module 6 is very important. The existing method for improving the radiator of the inverter module 6 of the outdoor unit of the air conditioner is generally to optimize the body of the radiator. The space of the outdoor unit is limited, and the optimization space of the radiator body is very small, so that the heat dissipation performance of the radiator is limited. The embodiment of the present invention provides a heat sink with high heat dissipation capability with two heat dissipation modules, which can dissipate the heat generated by the frequency conversion module 6 in time, thereby improving the reliability and stability of the operation of the frequency conversion module 6 .
本发明实施例提供的散热器的散热能力表现为：环境温度为52℃时，采用现有的散热器进行散热时，现有的散热器可以是非一体成型的散热器，大功率元器件的壳温为九十多摄氏度，甚至超过100℃，采用本发明实施例提供的散热器对变频模块6进行降温，环境温度为52℃时，大功率元器件壳温为72-82℃。可见，本发明实施例提供的散热器比现有的散热器给大功率元器件多降20-25℃。The heat dissipation capability of the radiator provided by the embodiment of the present invention is shown as follows: when the ambient temperature is 52° C., when the existing radiator is used for heat dissipation, the existing radiator may be a non-integrated radiator, and the shell of the high-power component can be used for heat dissipation. When the temperature is more than 90 degrees Celsius, or even more than 100 degrees Celsius, the heat sink provided by the embodiment of the present invention is used to cool down the frequency conversion module 6. When the ambient temperature is 52 degrees Celsius, the case temperature of the high-power components is 72-82 degrees Celsius. It can be seen that the heat sink provided by the embodiment of the present invention can lower the temperature of high-power components by 20-25° C. compared with the existing heat sink.
采用本发明实施例提供的散热器对变频模块6进行散热的方法可以是：第一散热模块1接收来自于变频模块6的热量，通过风冷散失部分热量，未散失的热量被第一工质流路中的工质吸收，工质受热后快速汽化并将热量带走，通过第一管路3进入第二散热模块2的第二工质流路25，第二散热模块2可以同时进行风冷散热和自然对流，第二工质流路25内的气体工质通过第二散热模块2将热量散热，降低温度后，变为液体，液态的工质通过第二管路4流回第一散热模块1的第一工质流路内，进行下一个吸热变为气态的循环。可见，采用本发明实施例提供的散热器对变频模块6进行散热时，可通过第一散热模块1与第二散热模块2同时对变频模块6进行散热，提高了散热器的散热能力，可将变频模块6产生的热量有效散失，保证了变频模块6的顺利运行，进而保证了空调器运行的可靠性。The method for dissipating heat from the frequency conversion module 6 by using the heat sink provided in the embodiment of the present invention may be as follows: the first heat dissipation module 1 receives the heat from the frequency conversion module 6, dissipates part of the heat through air cooling, and the undissipated heat is dissipated by the first working medium The working medium in the flow path is absorbed, the working medium is rapidly vaporized after being heated, and the heat is taken away, and then enters the second working medium flow path 25 of the second heat dissipation module 2 through the first pipeline 3, and the second heat dissipation module 2 can simultaneously conduct ventilation. Cold heat dissipation and natural convection, the gas working medium in the second working medium flow path 25 dissipates heat through the second heat dissipation module 2, and after the temperature is lowered, it becomes liquid, and the liquid working medium flows back to the first working medium through the second pipeline 4 In the first working medium flow path of the heat dissipation module 1, the next cycle of absorbing heat and changing to a gaseous state is performed. It can be seen that when the heat sink provided by the embodiment of the present invention is used to dissipate heat to the frequency conversion module 6, the first heat dissipation module 1 and the second heat dissipation module 2 can simultaneously dissipate heat to the frequency conversion module 6, which improves the heat dissipation capability of the heat sink, and can The heat generated by the frequency conversion module 6 is effectively dissipated, which ensures the smooth operation of the frequency conversion module 6, thereby ensuring the reliability of the operation of the air conditioner.
