下面参考图1描述根据本发明实施例的用于机房102服务器101的冷却系统100。The following describes a cooling system 100 for a server 101 in a computer room 102 according to an embodiment of the present invention with reference to FIG. 1 .
其中，如图1所示，机房102具有进风口10和排风口11，机房102地面的上方设有架空地板9以在机房102地面与架空地板9之间限定出与进风口10连通的进风道6，架空地板9上可开设有多个通孔，这样进风道6内的冷空气便可通过这些通孔进入冷过道内，然后通过冷过道两侧的服务器101并带走服务器101工作时产生的热量。Wherein, as shown in Figure 1, the machine room 102 has an air inlet 10 and an air outlet 11, and a raised floor 9 is provided above the ground of the machine room 102 to define an air inlet communicated with the air inlet 10 between the machine room 102 ground and the raised floor 9. The air duct 6 and the raised floor 9 can be provided with a plurality of through holes, so that the cold air in the air inlet duct 6 can enter the cold aisle through these through holes, and then pass through the servers 101 on both sides of the cold aisle and take away the servers 101 heat generated during work.
服务器101设置在架空地板9的上面并且服务器101的上方设有与排风口11连通的回风道7，进风口10和排风口11处均可设置有风门，用于控制进风口10和排风口11的开闭。其中回风道7可由天花板与机房102的内顶面限定出，天花板上可开设有多个通孔，这样对服务器101冷却后的高温空气便可从热过道通过这些通孔回流到回风道7中。The server 101 is arranged above the raised floor 9 and the top of the server 101 is provided with a return air passage 7 communicated with the air outlet 11, and the air inlet 10 and the air outlet 11 can be provided with dampers for controlling the air inlet 10 and the air outlet 11. The opening and closing of the air outlet 11. Wherein the air return duct 7 can be defined by the ceiling and the inner top surface of the machine room 102, and a plurality of through holes can be provided on the ceiling, so that the high-temperature air after cooling the server 101 can flow back to the air return duct from the hot aisle through these through holes 7 in.
根据本发明实施例的用于机房102服务器101的冷却系统100包括：过滤组件1、风机2、空调组件3和冷却塔4。A cooling system 100 for a server 101 in a computer room 102 according to an embodiment of the present invention includes: a filter assembly 1 , a fan 2 , an air conditioning assembly 3 and a cooling tower 4 .
其中过滤组件1设在机房102内且邻近进风口10。过滤组件1用于过滤室外空气中对服务器101有害的杂质例如粉尘、氮化物和硫化物等，使室外空气的质量达到可冷却服务器101的标准，避免在使用室外新风冷却服务器101时，服务器101受到不达标室外空气的影响。因此过滤组件1设在机房102内且邻近进风口10，这样能够及时、高效地过滤室外空气，使进入到室内的空气质量更好。The filter assembly 1 is disposed in the machine room 102 and adjacent to the air inlet 10 . The filter assembly 1 is used to filter impurities harmful to the server 101 in the outdoor air, such as dust, nitrides and sulfides, so that the quality of the outdoor air can reach the standard for cooling the server 101, so as to prevent the server 101 from being damaged when using outdoor fresh air to cool the server 101. Exposure to substandard outdoor air. Therefore, the filter assembly 1 is arranged in the machine room 102 and adjacent to the air inlet 10, so that the outdoor air can be filtered in a timely and efficient manner, so that the quality of the air entering the room is better.
例如在本发明的一个实施例中，过滤组件1包括第一过滤器、第二过滤器和第三过滤器。其中，第一过滤器用于过滤空气中的粉尘，从而降低进入机房102内的空气中的粉尘含量。具体地说，粉尘不仅会造成电气设备短路，而且会使电气开关接触不良，通过设置第一过滤器过滤进入机房102内的空气中的粉尘，降低该部分空气中的粉尘含量就可以大大降低发生电气设备短路和电气开关接触不良问题的几率，从而使服务器101能够更加长久且更加稳定地工作运行。For example, in one embodiment of the present invention, the filter assembly 1 includes a first filter, a second filter and a third filter. Wherein, the first filter is used to filter the dust in the air, thereby reducing the dust content in the air entering the machine room 102 . Specifically, dust will not only cause short circuit of electrical equipment, but also cause poor contact of electrical switches. By setting the first filter to filter the dust in the air entering the machine room 102, reducing the dust content in this part of the air can greatly reduce the occurrence of The possibility of short circuit of electrical equipment and poor contact of electrical switches enables the server 101 to work longer and more stably.
第二过滤器用于过滤空气中的氮化物，从而降低进入机房102内的空气中的氮化物含量。具体地说，氮化物会对服务器101造成腐蚀损害，容易导致电气设备的短路，从而影响服务器101的正常工作。因此过滤进入机房102内的空气中的氮化物，降低该部分空气中的氮化物含量可以使服务器101更长久且更稳定地工作运行。The second filter is used to filter nitrogen compounds in the air, thereby reducing the content of nitrogen compounds in the air entering the equipment room 102 . Specifically, the nitrides may cause corrosion damage to the server 101 , which may easily lead to a short circuit of electrical equipment, thereby affecting the normal operation of the server 101 . Therefore, filtering the nitrides in the air entering the computer room 102 and reducing the nitrogen content in this part of the air can make the server 101 work longer and more stably.
第三过滤器用于过滤空气中的硫化物，从而降低进入机房102内的空气中的硫化物含量。硫化物也会对服务器101造成腐蚀损害，容易导致电气设备的短路，影响服务器101的正常工作。因此过滤进入机房102内的空气中的硫化物，降低该部分空气中的硫化物含量可以使服务器101更长久且更稳定地工作运行。The third filter is used to filter sulfur compounds in the air, thereby reducing the content of sulfur compounds in the air entering the machine room 102 . The sulfides will also cause corrosion damage to the server 101 , easily lead to a short circuit of electrical equipment, and affect the normal operation of the server 101 . Therefore, filtering the sulfide in the air entering the computer room 102 and reducing the sulfide content in this part of the air can make the server 101 work longer and more stably.
由此，经过过滤组件1中的第一过滤器、第二过滤器、第三过滤器过滤后，从进风口10进入机房102内的空气中含有更少的粉尘、氮化物、硫化物，换句话说，从进风口10进入机房102内的空气中的有害物质更少，质量变得更好，从而可以大大减少这些有害杂质对服务器101的腐蚀和损坏，使服务器101工作的更稳定，同时提高了服务器101的使用寿命。Thus, after filtering through the first filter, the second filter, and the third filter in the filter assembly 1, the air entering the machine room 102 from the air inlet 10 contains less dust, nitrides, and sulfides. In other words, there are fewer harmful substances in the air entering the computer room 102 from the air inlet 10, and the quality becomes better, thereby greatly reducing the corrosion and damage of these harmful impurities to the server 101, making the server 101 work more stably, and at the same time The service life of the server 101 is improved.
需要说明的是，关于用于过滤粉尘的第一过滤器、用于过滤氮化物的第二过滤器以及用于过滤硫化物的第三过滤器的构造以及工作原理均已为现有技术，这里不再详细说明。It should be noted that the structure and working principle of the first filter for filtering dust, the second filter for filtering nitrogen and the third filter for filtering sulfide are all prior art, here No more details.
风机2设在过滤组件1的下游侧以将经过过滤组件1过滤后的空气导流至进风道6内。这里，需要说明的是，该“下游侧”指的是机房102内用于冷却服务器102的空气的流动方向的下游侧，换言之，风机2在空气流动方向上设在过滤组件1的下游侧。在下面关于“下游侧”的描述中，如果没有特殊说明，“下游侧”均作“在空气流动方向上的下游侧”理解，其中机房102内空气的流动方向如图1中所示的A方向。The fan 2 is arranged on the downstream side of the filter assembly 1 to guide the air filtered by the filter assembly 1 into the air inlet channel 6 . Here, it should be noted that the “downstream side” refers to the downstream side of the flow direction of the air used to cool the server 102 in the computer room 102 , in other words, the fan 2 is disposed on the downstream side of the filter assembly 1 in the air flow direction. In the following description about the "downstream side", if there is no special explanation, the "downstream side" is understood as "the downstream side in the air flow direction", wherein the flow direction of the air in the machine room 102 is as shown in Figure 1 A direction.
在风机2的强导风作用下，大量过滤后质量达标的空气更迅速地被送到进风道6内，更高效地实现空气流动。该部分空气经过进风道6以及架空地板9上的通孔后进入到冷通道14内，然后分别流经两边的服务器101，带走服务器101的热量，降低服务器101的温度，最后从热通道15进入回风道7中。需要说明的是，关于“冷过道”和“热过道”已为现有技术且为本领域的技术人员所熟知，这里不再详细说明。Under the strong air guide effect of the fan 2, a large amount of filtered air of qualified quality is sent to the air inlet channel 6 more quickly, and the air flow is realized more efficiently. This part of the air enters the cold aisle 14 after passing through the air inlet duct 6 and the through holes on the raised floor 9, and then flows through the servers 101 on both sides respectively, taking away the heat of the servers 101, reducing the temperature of the servers 101, and finally passing through the hot aisle. 15 into the return air duct 7. It should be noted that the “cold aisle” and the “hot aisle” are known to those skilled in the art and will not be described in detail here.
例如在本发明的一个实施例中，风机2设置在一个混合室5内。混合室5设在过滤组件1的下游侧，混合室5分别与进风道6和回风道7连通。风机2可以使混合室5内的空气加速进入进风道6，更高效的实现空气流动。For example, in one embodiment of the invention, the blower 2 is arranged in a mixing chamber 5 . The mixing chamber 5 is arranged on the downstream side of the filter assembly 1 , and the mixing chamber 5 communicates with the air inlet channel 6 and the air return channel 7 respectively. The fan 2 can accelerate the air in the mixing chamber 5 to enter the air inlet channel 6, so as to realize air flow more efficiently.
空调组件3设在机房102内。空调组件3主要作用是降低机房102内空气的温度，使室内空气的温度能够满足服务器101正常工作温度的要求，从而使服务器101更高效稳定地工作。具体地，空调组件3具有空调末端（即空调组件的末端设置），空调末端内具有冷媒，对服务器101冷却后的空气温度升高形成为高温空气，高温空气可以从回风道7回流至空调末端并与冷媒热交换变为低温空气，低温空气进入进风道6内并从架空地板9上的通孔进入冷过道以对服务器101冷却，冷却后重新变为高温空气进入回风道7内，完成一个制冷循环。The air conditioner assembly 3 is located in the machine room 102 . The main function of the air conditioning unit 3 is to reduce the temperature of the air in the computer room 102, so that the temperature of the indoor air can meet the requirements of the normal working temperature of the server 101, so that the server 101 can work more efficiently and stably. Specifically, the air-conditioning assembly 3 has an air-conditioning terminal (i.e., the end of the air-conditioning assembly is set), and there is a refrigerant in the air-conditioning terminal, and the temperature of the air cooled by the server 101 is raised to form high-temperature air, and the high-temperature air can be returned to the air conditioner from the return air duct 7. The end exchanges heat with the refrigerant to become low-temperature air. The low-temperature air enters the air inlet duct 6 and enters the cold aisle from the through hole on the raised floor 9 to cool the server 101. After cooling, it becomes high-temperature air again and enters the return air duct 7. , to complete a refrigeration cycle.
在本发明的一个实施例中，空调组件3优选在关闭进风口10和排风口11后使用，在可以使用室外空气对机房102内的服务器101冷却时，空调组件3可以不工作，这样就可以降低机房102的能源消耗，节省机房102的使用维护费用。In one embodiment of the present invention, the air-conditioning assembly 3 is preferably used after closing the air inlet 10 and the air exhaust port 11. When outdoor air can be used to cool the server 101 in the machine room 102, the air-conditioning assembly 3 can not work, so that The energy consumption of the computer room 102 can be reduced, and the use and maintenance costs of the computer room 102 can be saved.
冷却塔4设在机房102外，冷却塔4与空调组件3之间连接有回水管路13和出水管路12。空调末端内的低温冷媒与高温回风换热后变为高温冷媒，高温冷媒可从回水管路13流向冷却塔4并在冷却塔4处向外放热变为低温冷媒，低温冷媒从出水管路12回流至空调末端重新与高温回风换热，完成一次循环。可以理解的是，冷媒可为水，当然也可为其它冷却介质。The cooling tower 4 is arranged outside the machine room 102 , and a return water pipeline 13 and a water outlet pipeline 12 are connected between the cooling tower 4 and the air conditioning unit 3 . The low-temperature refrigerant in the air conditioner end exchanges heat with the high-temperature return air and becomes a high-temperature refrigerant. The high-temperature refrigerant can flow from the return pipe 13 to the cooling tower 4 and release heat from the cooling tower 4 to become a low-temperature refrigerant. The low-temperature refrigerant flows from the outlet pipe Road 12 returns to the end of the air conditioner to exchange heat with the high-temperature return air again, completing a cycle. It can be understood that the refrigerant can be water, and of course it can also be other cooling media.
在本发明的一个实施例中，出水管路12和/或回水管路13上设有水泵8。具体地说，有三种情况，第一种情况是出水管路12上设有水泵8，而回水管路13上没有设水泵8。第二种情况是出水管路12上没有设水泵8，而回水管路13上设有水泵8。第三种情况是不仅出水管路12上设有水泵8，而且回水管路13上也设有水泵8。通过设置水泵8可以更顺利地实现出水和回水的过程，使水循环更顺畅，更稳定。In one embodiment of the present invention, a water pump 8 is provided on the water outlet pipeline 12 and/or the water return pipeline 13 . Specifically, there are three situations. The first situation is that a water pump 8 is provided on the water outlet pipeline 12 , but no water pump 8 is provided on the return water pipeline 13 . The second situation is that the water pump 8 is not provided on the water outlet pipeline 12 , but the water pump 8 is provided on the return water pipeline 13 . The third situation is that not only the water pump 8 is provided on the water outlet pipeline 12 , but also the water pump 8 is also provided on the return water pipeline 13 . The process of water outlet and water return can be realized more smoothly by setting the water pump 8, so that the water circulation is smoother and more stable.
进一步地，回水管路13和出水管路12均为隔热管，例如回水管路13和出水管路12均由隔热材料制成的管路。由此可以防止回水管路13和出水管路12中的冷媒与外部空气换热，可以进一步减少能量的损失，保证热交换的稳定高效，从而使得回水管路13和出水管路12具有保温和防结露功能。Further, both the water return pipeline 13 and the water outlet pipeline 12 are heat-insulated pipes, for example, the water return pipeline 13 and the water outlet pipeline 12 are both made of heat-insulating materials. This can prevent the refrigerant in the return water pipeline 13 and the water outlet pipeline 12 from exchanging heat with the outside air, further reduce energy loss, and ensure stable and efficient heat exchange, so that the return water pipeline 13 and the water outlet pipeline 12 have heat preservation and Anti-condensation function.
此外，在本发明的一个实施例中，冷却系统100还包括传感器组件16，该传感器组件16设在机房102外用于检测机房102外的温度和空气质量，并判断其是否达到可用于冷却服务器101的标准。具体地说，该传感器组件16用于检测机房102外空气的颗粒物的含量、氮化物的含量和硫化物的含量。In addition, in one embodiment of the present invention, the cooling system 100 also includes a sensor assembly 16, the sensor assembly 16 is arranged outside the computer room 102 for detecting the temperature and air quality outside the computer room 102, and judging whether it can be used to cool the server 101 standard. Specifically, the sensor assembly 16 is used to detect the content of particles, nitrides and sulfides in the air outside the computer room 102 .
进一步地，当传感器组件16检测室外空气中颗粒物的含量低于0.1mg/m3、氮化物的含量低于0.05mg/m3、硫化物的含量低于0.02mg/m3时，则机房102外的空气质量达标，若颗粒物、氮化物和硫化物的含量中至少一项高于相应值时，则机房102外的空气质量不达标。Further, when the sensor assembly 16 detects that the content of particulate matter in the outdoor air is less than 0.1 mg/m3 , the content of nitrides is less than 0.05 mg/m3 , and the content of sulfides is less than 0.02 mg/m3 , then the computer room 102 If the air quality outside the machine room 102 is up to the standard, if the content of at least one of the particles, nitrides and sulfides is higher than the corresponding value, the air quality outside the computer room 102 is not up to the standard.
换句话说，当室外空气中颗粒物的含量等于或者大于0.1mg/m3、氮化物的含量等于或者大于0.05mg/m3、硫化物的含量等于或者大于0.02mg/m3时，则认为室外空气质量较差，可能对服务器101造成损伤，不适于冷却服务器101，因此此时可关闭进风口10和排气口11，只使用空调组件3对机房102降温以冷却服务器101。In other words, when the content of particulate matter in the outdoor air is equal to or greater than 0.1 mg/m3 , the content of nitrides is equal to or greater than 0.05 mg/m3 , and the content of sulfide is equal to or greater than 0.02 mg/m3 , it is considered that the outdoor The air quality is poor, which may cause damage to the server 101 and is not suitable for cooling the server 101. Therefore, the air inlet 10 and the exhaust port 11 can be closed at this time, and only the air conditioning unit 3 is used to cool the computer room 102 to cool the server 101.
可以理解的是，本发明并不限于此，室外空气的颗粒物的含量、氮化物的含量和硫化物的含量的大小可根据服务器101的耐环境能力决定的。具体地说，当服务器101的耐环境能力较强时，颗粒物的含量、氮化物的含量和硫化物的含量的阀值大小可以相应的大一些，也就是说，传感器组件16检测满足标准的空气质量的阀值可以设置的大一些，容许在空气中含有更多的颗粒物、氮化物和硫化物。例如设置传感器组件16，使室外空气中颗粒物的含量阀值为0.2mg/m3，氮化物的含量阀值为0.08mg/m3，硫化物的含量阀值为0.05mg/m3，则当传感器组件16检测室外空气中颗粒物的含量低于0.2mg/m3、氮化物的含量低于0.08mg/m3、硫化物的含量低于0.05mg/m3时，认为机房102外的空气质量达标。It can be understood that the present invention is not limited thereto, and the content of particulates, nitrides and sulfides in the outdoor air can be determined according to the environmental resistance capability of the server 101 . Specifically, when the server 101 has a strong environmental resistance capability, the threshold values of the particulate matter content, nitride content and sulfide content can be correspondingly larger, that is to say, the sensor assembly 16 detects air that meets the standard. The quality threshold can be set larger to allow more particles, nitrides and sulfides in the air. For example, the sensor assembly 16 is set so that the threshold value of particulate matter in outdoor air is 0.2 mg/m3 , the threshold value of nitride content is 0.08 mg/m3 , and the threshold value of sulfide content is 0.05 mg/m3 , then when When the sensor component 16 detects that the content of particulate matter in the outdoor air is less than 0.2 mg/m3 , the content of nitrides is less than 0.08 mg/m3 , and the content of sulfides is less than 0.05 mg/m3 , the air quality outside the computer room 102 is considered to be Up to standard.
下面详细描述根据本发明实施例的冷却系统100的优选工作模式。The preferred working mode of the cooling system 100 according to the embodiment of the present invention will be described in detail below.
在本发明的一个实施例中，当传感器组件16检测机房102外的空气质量不达标时，进风口10关闭且空调组件3启动工作。这时机房102内部的温度由空调组件3调节，避免了室外空气中的颗粒物、氮化物和硫化物对服务器101的损害。In one embodiment of the present invention, when the sensor assembly 16 detects that the air quality outside the machine room 102 is not up to standard, the air inlet 10 is closed and the air conditioning assembly 3 starts to work. At this time, the temperature inside the computer room 102 is regulated by the air-conditioning assembly 3 , which avoids damage to the server 101 by particles, nitrides and sulfides in the outdoor air.
在本发明的一个实施例中，当机房102外的空气质量达标，且机房102外的空气温度低于第一预定温度时，从进风口10进入到机房102内的空气对服务器101冷却后、至少一部分回流至进风口10处并与从进风口10进入的空气混合。In one embodiment of the present invention, when the air quality outside the computer room 102 reaches the standard, and the air temperature outside the computer room 102 is lower than the first predetermined temperature, the air entering the computer room 102 from the air inlet 10 is cooled to the server 101, At least part of it flows back to the air inlet 10 and mixes with the air entering from the air inlet 10 .
由于室外空气温度较低，直接冷却服务器101容易出现结露现象，且结露对服务器101有较大的损坏，因此为了避免这种情况的发生，当室外空气温度低于第一预定温度时，冷却服务器101后的高温空气会通过回风道7一部分回流至进风口10处并与从进风口10新进入的低温空气混合，也就是说，冷却服务器101后的高温空气预热了新进的低温空气，这样可以提高用于冷却服务器101的混合气体的温度，从而避免出现结露现象。Due to the low temperature of the outdoor air, the direct cooling of the server 101 is prone to dew condensation, and the dew condensation will cause great damage to the server 101. Therefore, in order to avoid this situation, when the outdoor air temperature is lower than the first predetermined temperature, The high-temperature air after cooling the server 101 will return to the air inlet 10 through the air return channel 7 and mix with the low-temperature air newly entering from the air inlet 10, that is to say, the high-temperature air after cooling the server 101 preheats the newly entered air. Low-temperature air, which can increase the temperature of the mixed gas used to cool the server 101, thereby avoiding condensation.
进一步地，为了更好地混合冷热空气，冷却系统100还包括混合室5，混合室5设在过滤组件1的下游侧，混合室5分别与进风道6和回风道7连通。Further, in order to better mix the hot and cold air, the cooling system 100 further includes a mixing chamber 5, which is arranged on the downstream side of the filter assembly 1, and the mixing chamber 5 communicates with the air inlet channel 6 and the air return channel 7 respectively.
在混合室5内，从进风口10新进的低温空气和从回风道7回流的高温空气混合，高温空气预热了低温空气，使混合气体的温度能够高于第一预定温度，这样混合空气对服务器101冷却时可以避免出现结露现象。In the mixing chamber 5, the low-temperature air newly introduced from the air inlet 10 is mixed with the high-temperature air returned from the return air passage 7, and the high-temperature air preheats the low-temperature air, so that the temperature of the mixed gas can be higher than the first predetermined temperature, so that the mixture Condensation can be avoided when the air cools the server 101 .
更进一步地，冷却系统100中还包括混合风扇（图未示出），混合风扇设置在混合室5内，用于加速混合高温空气和低温空气。在混合室5内，混合风扇旋转，加速空气的流动，促进了高温空气和低温空气的充分混合，使混合过程更快速且更均匀。Furthermore, the cooling system 100 also includes a mixing fan (not shown in the figure), which is arranged in the mixing chamber 5 for accelerating mixing of high-temperature air and low-temperature air. In the mixing chamber 5, the mixing fan rotates to accelerate the flow of air, which promotes the thorough mixing of high-temperature air and low-temperature air, and makes the mixing process faster and more uniform.
在本发明的一个实施例中，当传感器组件16检测机房102外的空气质量达标，且机房102外的空气温度高于第一预定温度且低于第二预定温度时，从进风口10进入机房102内的空气对服务器101冷却后直接从排风口11排出。也就是说，当室外空气温度介于第一预定温度和第二预定温度之间时，则认为室外空气较适合冷却服务器101，室外空气不需要预热，不会出现结露现象，对服务器101冷却效果稳定，因此可直接从排风口11排出，这样提高了冷却的效率。In one embodiment of the present invention, when the sensor assembly 16 detects that the air quality outside the machine room 102 is up to standard, and the air temperature outside the machine room 102 is higher than the first predetermined temperature and lower than the second predetermined temperature, enter the machine room from the air inlet 10 The air in 102 is directly discharged from the air outlet 11 after the server 101 is cooled. That is to say, when the outdoor air temperature is between the first predetermined temperature and the second predetermined temperature, it is considered that the outdoor air is more suitable for cooling the server 101, and the outdoor air does not need to be preheated, and no dew condensation will occur. The cooling effect is stable, so it can be directly discharged from the air outlet 11, which improves the cooling efficiency.
在本发明的一个实施例中，当传感器组件16检测机房102外的空气质量达标且机房102外的空气温度高于第二预定温度时，进风口10和排风口11关闭且空调组件3启动工作。换言之，当室外空气温度高于第二预定温度时，认为室外空气温度过高，不适合用于冷却服务器101或者对服务器101冷却不足，容易导致服务器101温度过高而损坏，因此此时关闭进风口10和排风口11，直接采用空调组件3和冷却塔4进行冷却。In one embodiment of the present invention, when the sensor assembly 16 detects that the air quality outside the machine room 102 is up to standard and the air temperature outside the machine room 102 is higher than the second predetermined temperature, the air inlet 10 and the air outlet 11 are closed and the air conditioning assembly 3 is started. Work. In other words, when the outdoor air temperature is higher than the second predetermined temperature, it is considered that the outdoor air temperature is too high, which is not suitable for cooling the server 101 or insufficient cooling of the server 101, which may easily cause the server 101 to be overheated and damaged. The tuyere 10 and the air outlet 11 are directly cooled by the air conditioning unit 3 and the cooling tower 4 .
需要说明的是，上述的第一预定温度和第二预定温度是根据不同服务器102的标定工作温度来设定的，也就是说，对于两种不同的服务器102，其第一预定温度或第二预定温度一般是不同的。另外，上述中的空气温度可以理解为空气干球温度。It should be noted that the above-mentioned first predetermined temperature and second predetermined temperature are set according to the calibrated operating temperatures of different servers 102, that is, for two different servers 102, the first predetermined temperature or the second predetermined temperature The predetermined temperatures are generally different. In addition, the air temperature mentioned above can be understood as the air dry bulb temperature.
在本发明的一些优选实施例中，服务器101可以是高温服务器101，高温服务器101可以承受的工作温度一般不超过40℃，因此，第一预定温度可以设置为18℃，第二预定温度可以设置为38℃。当然，容易理解的是，对于不同服务器101，其所能承受的工作温度一般也不同，也就是说，对于其它类型的服务器101，其第一预定温度可以是18℃，当然也可以高于或低于18℃，其第二预定温度可以是38℃，当然也可以低于或高于38℃，这里以第一预定温度为18℃，第二预定温度为38℃仅是示意性地说明，不能理解为对本发明的限制。In some preferred embodiments of the present invention, the server 101 can be a high-temperature server 101, and the working temperature that the high-temperature server 101 can withstand generally does not exceed 40°C. Therefore, the first predetermined temperature can be set to 18°C, and the second predetermined temperature can be set to is 38°C. Of course, it is easy to understand that for different servers 101, the operating temperatures they can withstand are generally different, that is to say, for other types of servers 101, the first predetermined temperature may be 18°C, and of course it may be higher than or If it is lower than 18°C, the second predetermined temperature can be 38°C, and of course it can also be lower than or higher than 38°C. Here, the first predetermined temperature is 18°C, and the second predetermined temperature is 38°C. It should not be construed as a limitation of the present invention.
在本发明的一个实施例中，传感器组件16还用于检测机房102外的空气湿度，且当传感器组件16检测机房102外的空气湿度高于第一预定值时，进风口10关闭且空调组件3启动工作。当室外空气的湿度太大时，室外空气在进行冷却的过程中，会加重服务器101的腐蚀。In one embodiment of the present invention, the sensor assembly 16 is also used to detect the air humidity outside the machine room 102, and when the sensor assembly 16 detects that the air humidity outside the machine room 102 is higher than the first predetermined value, the air inlet 10 is closed and the air conditioning assembly 3 Start the job. When the humidity of the outdoor air is too high, the corrosion of the server 101 will be aggravated during the cooling process of the outdoor air.
进一步地，该第一预定值为70％。换句话说，当室外空气湿度大于70％时，进风口10和排风口11关闭，空调组件3启动工作，只依靠空调组件3来冷却服务器101，维持机房102合适的工作温度。Further, the first predetermined value is 70%. In other words, when the outdoor air humidity is greater than 70%, the air inlet 10 and the air outlet 11 are closed, the air conditioner 3 starts to work, and only the air conditioner 3 is used to cool the server 101 and maintain an appropriate working temperature of the computer room 102.
总而言之，根据本发明实施例的用于机房102服务器101的冷却系统100，可根据室外空气质量以及室外温度、湿度等来选择性地使用室外新风对服务器冷却或者使用空调组件对服务器冷却，充分利用了室外新风，能够更加有效地降低机房102的运行成本，而且该冷却系统简单可靠，维护简单，节能效果显著。此外，对于高温机房102（例如设置高温服务器101的机房），节能效果尤为显著，因此可通过在高温机房102设置本发明的冷却系统从而获得更好的冷却效果，同时最大限度地利用室外新风、降低运行成本。In a word, according to the cooling system 100 for the server 101 in the computer room 102 according to the embodiment of the present invention, it can selectively use outdoor fresh air to cool the server or use air conditioning components to cool the server according to the outdoor air quality, outdoor temperature, humidity, etc., making full use of The outdoor fresh air can be used to reduce the operating cost of the computer room 102 more effectively, and the cooling system is simple and reliable, easy to maintain, and has a remarkable energy-saving effect. In addition, for the high-temperature computer room 102 (such as the computer room where the high-temperature server 101 is installed), the energy-saving effect is particularly significant, so the cooling system of the present invention can be installed in the high-temperature computer room 102 to obtain a better cooling effect, and at the same time make maximum use of outdoor fresh air, Reduce operating costs.
根据本发明实施例的用于机房102服务器101的冷却系统100的其他构成例如风门等以及操作对于本领域普通技术人员而言都是已知的，这里不再详细描述。Other components of the cooling system 100 for the server 101 in the computer room 102 according to the embodiment of the present invention, such as dampers, and operations are known to those skilled in the art, and will not be described in detail here.
