[0043] In order to enable those skilled in the art to better understand the technical solutions in this specification, the technical solutions in the embodiments of this specification will be clearly and completely described below in conjunction with the drawings in the embodiments of this specification. Obviously, the described embodiments are only part of the embodiments of this specification, not all of the embodiments. Based on the embodiments in this specification, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of this specification.

[0044] The embodiment of this specification provides a server chip liquid cooling device. When it is implemented, refer to Figure 1 As shown, the device includes: a first heat pipe evaporation end 10, a first heat pipe condensation end 30, a nozzle 40, a dehumidifier 60, a condenser 100, a compressor 70, a throttle valve 110, and an air filter 50, wherein:

[0045] The first heat pipe evaporation end 10 is located on the surface of the to-be-cooled element 20, the output end of the first heat pipe evaporation end 10 is connected to the input end of the first heat pipe condensation end 30, the output end of the first heat pipe condensation end 30 is connected to the input end of the first heat pipe evaporation end 10, and the first heat pipe condensation end 30 is located within the water spraying range of the nozzle 40;

[0046] The output end of the air filter 50 is connected to the input end of the dehumidifier 60 through the first air duct 80 and the second air duct 90. The output end of the dehumidifier 60 corresponding to the first air duct 80 is located on one side of the first heat pipe condensation end 30.

[0047] The condenser 100 is located on a side of the second air duct 90 adjacent to the dehumidifier 60, the output end of the first heat pipe condensation end 30 is connected to the input end of the compressor 70, the output end of the compressor 70 is connected to the input end of the condenser 100, the output end of the condenser 100 is connected to the input end of the throttle valve 110, and the output end of the throttle valve 110 is connected to the input end of the first heat pipe condensation end 30.

[0048] Among them, the element to be cooled 20 can be a server chip, and the first heat pipe evaporator end 10 can be located on any side of the surface of the element to be cooled 20, so that after the element to be cooled 20 is heated, the heat generated by the element to be cooled 20 can be transferred to the first heat pipe evaporator end 10 through heat conduction. In this way, the low-temperature liquid working fluid in the first heat pipe evaporator end 10 can be converted into high-temperature steam working fluid after obtaining heat, and the high-temperature steam working fluid can be transmitted to the first heat pipe condensation end 30.

[0049] Among them, the first heat pipe condensing end 30 can be a shell and tube heat exchanger, and the circulating medium between the first heat pipe condensing end 30 and the first heat pipe evaporating end 10 can be a medium-low temperature environmentally friendly refrigerant (R134a), that is, the first heat pipe evaporating end 10 can transport the high-temperature steam working medium (that is, the medium-low temperature environmentally friendly refrigerant in the form of high-temperature steam working medium) generated during the cooling process to the first heat pipe condensing end 30, and the first heat pipe condensing end 30 can transport the low-temperature liquid working medium (that is, the medium-low temperature environmentally friendly refrigerant in the form of low-temperature liquid working medium) to the first heat pipe evaporating end 10.

[0050] The dehumidifier 60 may be a rotary dehumidifier, and the dehumidifier in the dehumidifier 60 may be silica gel or activated carbon.

[0051] In addition, if Figure 1As shown, there may be multiple components 20 to be cooled, and one first heat pipe evaporation end 10 may be allocated to each component 20 to be cooled, and the multiple first heat pipe evaporation ends 10 may be connected in parallel. Alternatively, the multiple components 20 to be cooled may be arranged in a stacked manner, and one or more first heat pipe evaporation ends 10 may be configured on the surface of the stacked components 20 to be cooled.

[0052] Based on the above embodiment, the air filter 50 can filter the outdoor air and transport the filtered outdoor air to the first air duct 80 and the second air duct 90 respectively. The first heat pipe evaporator end 10 can cool the cooling element 20 and transport the high-temperature steam working medium generated in the cooling process to the first heat pipe condensation end 30. The compressor 70 can compress the low-temperature and low-pressure refrigerant vapor in the first heat pipe condensation end 30 into high-temperature and high-pressure refrigerant vapor, and transport the high-temperature and high-pressure refrigerant vapor to the condenser 100. The condenser 100 can perform heat exchange treatment on the high-temperature and high-pressure refrigerant vapor through the filtered outdoor air in the second air duct 90 to obtain condensed high-pressure refrigerant liquid and heated outdoor air. On the one hand, the throttle valve 110 can be used to reduce the pressure of the condensed high-pressure refrigerant liquid to obtain refrigerant liquid. The first heat pipe condensation end 30 can cool the high-temperature steam working medium input from the first heat pipe evaporation end 10 under the action of the refrigerant liquid, the water sprayed from the nozzle 40 and the air dehumidified by the dehumidifier 60 to obtain a low-temperature liquid working medium. The first heat pipe evaporation end 10 can cool the cooling element 20 through the low-temperature liquid working medium to reduce cooling energy consumption. On the other hand, the heated outdoor air can be used to drive away the moisture in the dehumidifier 60 to achieve the regeneration of the dehumidifier, avoiding the need to add additional devices to maintain the dehumidifier 60 and reducing maintenance costs.

[0053] In some embodiments, see Figure 2 As shown, the device further includes a second heat pipe evaporation end 120, a second heat pipe condensation end 130, a first liquid storage tank 140, a first refrigerant circulation pump 150, a second heat pipe evaporation end 120 and a collector 160, wherein:

[0054] The second heat pipe condensing end 130 is located between the condenser 100 and the air filter 50 in the second air duct 90, the collector 160 is located on the surface of the second heat pipe evaporating end 120, the output end of the collector 160 is connected to the input end of the second heat pipe condensing end 130, the output end of the second heat pipe condensing end 130 is connected to the input end of the first liquid storage tank 140, the output end of the first liquid storage tank 140 is connected to the input end of the first refrigerant circulation pump 150; the output end of the first refrigerant circulation pump 150 is connected to the input end of the second heat pipe evaporating end 120.

[0055] The collector 160 may be a solar collector, and specifically, the collector 160 may be a flat-plate solar collector.

[0056] In this way, the heat collector 160 can generate heat and transfer the generated heat to the second heat pipe evaporation end 120. The circulating working medium (such as R134a) in the second heat pipe evaporation end 120 can be vaporized into a high-temperature steam working medium after obtaining the heat, and the high-temperature steam working medium can be transported to the second heat pipe condensation end 130 through a pipeline. The high-temperature steam working medium can exchange heat with the outdoor air filtered by the second filter 52 in the second heat pipe condensation end 130, and the second heat pipe condensation end 130 is cooled to obtain a low-temperature liquid working medium, and the filtered outdoor air is heated to obtain outdoor air after preliminary heating.

[0057] On the one hand, the second heat pipe condensing end 130 can transport the low-temperature liquid working medium to the first liquid storage tank 140 for storage. In this way, the first refrigerant circulation pump 150 can transport the low-temperature liquid working medium stored in the first liquid storage tank 140 to the second heat pipe evaporation end 120, so that the second heat pipe evaporation end 120 can convert the low-temperature liquid working medium into a high-temperature steam working medium under the action of the heat generated by the collector 160, thereby realizing the circulation between the second heat pipe evaporation end 120 and the second heat pipe condensing end 130.

[0058] On the other hand, after the filtered outdoor air passes through the heat exchange at the second heat pipe condensation end 130, the outdoor air with preliminary temperature increase can be obtained. The outdoor air with preliminary temperature increase passes through the condenser 100 and performs heat exchange treatment on the high-temperature and high-pressure refrigerant vapor in the condenser 100 to obtain the outdoor air with temperature increase. In this way, the outdoor air with temperature increase can pass through the regeneration area of ​​the dehumidifier, so that the flow channel wall containing the dehumidifier in the regeneration area is heated. The water vapor partial pressure in the dehumidifier is higher than the water vapor partial pressure of the outdoor air with temperature increase, so that the moisture in the dehumidifier can be driven out, and the regeneration of the dehumidifier can be realized, avoiding the need to add additional devices to maintain the dehumidifier 60, and reducing the maintenance cost.

[0059] In some embodiments, see Figure 3 As shown, the device also includes a second liquid storage tank 170 and a second refrigerant circulation pump 180, wherein the output end of the first heat pipe condensation end 30 is connected to the input end of the first heat pipe evaporation end 10 through the second liquid storage tank 170 and the second refrigerant circulation pump 180 in sequence.

[0060] In this way, the low-temperature liquid working medium output by the first heat pipe condensing end 30 can be stored in the second liquid storage tank 170. When the first heat pipe evaporating end 10 needs low-temperature liquid working medium, the low-temperature liquid working medium stored in the second liquid storage tank 170 can be transported to the first heat pipe evaporating end 10 through the second refrigeration circulation pump, thereby realizing the circulation between the first heat pipe evaporating end 10 and the first heat pipe condensing end 30.

[0061] In some embodiments, see Figure 3 As shown, the device further includes a water receiving tray 190, a water pump 200 and a water baffle 210, wherein:

[0062] The water baffle 210 is located on one side of the steam rising direction in the first heat pipe condensation end 30, the water receiving tray 190 is located on one side of the liquid falling direction in the first heat pipe condensation end 30, the output end of the water receiving tray 190 is connected to the input end of the water pump 200, and the output end of the water pump 200 is connected to the input end of the nozzle 40.

[0063] After the dehumidified air flows through the first heat pipe condensation end 30, it contacts the water sprayed from the nozzle 40, and part of the water evaporates into the air. As the water evaporates, it can take away the heat of the first heat pipe condensation end 30, and the first heat pipe condensation end 30 is cooled. The high-temperature steam working medium in the first heat pipe condensation end 30 is converted into a low-temperature liquid working medium.

[0064] The water baffle 210 can be used to remove water droplets carried in the heated water, and the water receiving tray 190 can receive the water sprayed by the nozzle 40 and send it back to the nozzle 40 through the water pump 200 after natural cooling, thereby realizing indirect evaporative cooling.

[0065] In some embodiments, see Figure 3 As shown, the air filter 50 includes a first filter 51 and a second filter 52 , the first filter 51 is located in the first air duct 80 , and the second filter 52 is located in the second air duct 90 .

[0066] The first filter 51 and the second filter 52 can be controlled separately, so as to cool the first heat pipe condensation end 30 by controlling the first filter 51, and to regenerate the dehumidifier in the dehumidifier 60 by controlling the second filter 52, thereby saving operating costs and improving operating efficiency.

[0067] In some embodiments, see Figure 3 As shown, the device also includes a first air outlet 220 and a second air outlet 230. The first air outlet 220 is located on one side of the output end of the dehumidifier 60 corresponding to the second air duct 90, and the second air outlet 230 is located on one side of the water baffle 210 in the steam rising direction.

[0068] In this way, after the heated air passes through the water baffle 210 to remove the water droplets it carries, it can be discharged into the air through the second air outlet 230. Since the heated outdoor air has a higher humidity after being dehumidified by the dehumidifier 60, it can be discharged into the air through the first air outlet 220.

[0069] In some embodiments, see Figure 3As shown, the device further includes a first fan 240 and a second fan 250 . The first fan 240 is located between the second filter 52 and the second heat pipe condensation end 130 , and the second fan 250 is located between the second air outlet 230 and the water baffle 210 .

[0070] The first fan 240 can provide power to increase the pressure and flow rate of the filtered outdoor air. The first fan 240 can put the device in a negative pressure state.

[0091] The processor 602 may be specifically configured to send an opening instruction to the air filter 50 upon receiving a dehumidification instruction.

[0093] Based on the above method, the relevant structural performance of the electronic equipment can be effectively utilized, the data processing speed of the electronic equipment can be improved, and the server chip liquid cooling method can be efficiently implemented.

The memory can be used to store computer program instructions. The network communication unit can be an interface for network connection communication set in accordance with the standard specified by the communication protocol.

[0099] In this embodiment, the functions and effects specifically implemented by the program instructions stored in the computer-readable storage medium can be explained in comparison with other implementations and will not be described in detail here.

[0100] In a specific scenario example, a server chip liquid cooling device, system and equipment provided in this specification can be applied to fully utilize waste heat to regenerate the dehumidifier, thereby overcoming the problems of high energy consumption and high maintenance cost of the cooling device. The specific implementation process may include the following contents.

[0101] Since the humidity in different regions and under different climatic conditions is different, different devices can be controlled to be turned on and off according to different regions and climatic conditions, so that different working modes can be adopted for different regions and climatic conditions to reduce operating costs.

[0102] For example, situation one: under conditions of low temperature and humidity (such as the southern region in winter and the northern region in winter), the first filter 51 can be turned on, the element to be cooled 20 can be started, and the element to be cooled 20 generates heat when it is running. The heat can be transferred to the first heat pipe evaporator end 10 through heat conduction. The circulating working fluid in the first heat pipe evaporator end 10 vaporizes into high-temperature steam working fluid after obtaining the heat, the element to be cooled 20 is cooled, and the high-temperature steam working fluid can be transported to the first heat pipe condensation end 30 through a pipeline.

[0103] After being filtered by the first air filter 50, the outdoor air can enter the modular container (i.e., the environment where the devices other than the cooling element 20 and the first heat pipe evaporation end 10 are located). After the outdoor air flows through the first heat pipe condensation end 30 (i.e., the dehumidifier 60 is not turned on), heat exchange is performed, the first heat pipe condensation end 30 is cooled, and the high-temperature steam working medium in the first heat pipe condensation end 30 is condensed into a low-temperature liquid working medium after receiving the coldness of the outdoor air, while the outdoor air receives heat, and the outdoor air temperature rises. The operation of the second fan 250 can make the modular container in a negative pressure state, and the heated outdoor air can be discharged into the air through the second air outlet 230. The condensed low-temperature liquid working medium can enter the second liquid storage tank 170 for temporary storage to provide a stable liquid working medium for the first heat pipe evaporation end 10. The low-temperature liquid working medium stored in the second liquid storage tank 170 can be transported to the first heat pipe evaporation end 10 through the second refrigerant circulation pump 180. In this way, the cooling of the data center under the conditions of low temperature and humidity can be achieved.

[0104] Case 2: Under conditions of low humidity (such as the northern region in the transition season), the component to be cooled 20 is started. When the component to be cooled 20 is running, heat is generated, and the heat can be transferred to the first heat pipe evaporation end 10 through heat conduction. The circulating working fluid in the first heat pipe evaporation end 10 is vaporized into high-temperature steam working fluid after obtaining the heat, and the component to be cooled 20 is cooled. The high-temperature steam working fluid can be transported to the first heat pipe condensation end 30 through the pipeline.

[0105] The first filter 51 can be turned on, and the outdoor air can enter the modular container after being filtered through the first filter 51. The filtered outdoor air can contact the normal temperature circulating water sprayed by the nozzle 40 after flowing through the first heat pipe condensation end 30, and part of the circulating water evaporates into the air. The circulating water evaporates and absorbs the heat of the first heat pipe condensation end 30, and the temperature of the circulating water increases. At the same time, the air also absorbs part of the heat of the first heat pipe condensation end 30, and the temperature and humidity of the air increase. The first heat pipe condensation end 30 is cooled, and the high-temperature steam working medium in the first heat pipe condensation end 30 can be condensed into a low-temperature liquid working medium after obtaining cold.

[0106] The operation of the second fan 250 can put the modular container in a negative pressure state. After the heated air passes through the water baffle 210 to remove the water droplets it carries, it can be discharged into the air through the second air outlet 230. The circulating water after evaporative heat exchange can be collected by the water receiving tray 190, and after natural cooling, it is transported to the nozzle 40 through the water pump 200 and sprayed to the first heat pipe condensation end 30 to achieve indirect evaporative cooling. The condensed low-temperature liquid working medium can enter the second liquid storage tank 170 for temporary storage to provide a stable liquid working medium for the first heat pipe evaporation end 10. The low-temperature liquid working medium stored in the second liquid storage tank 170 can be transported to the first heat pipe evaporation end 10 through the second refrigerant circulation pump 180. Such a cycle can achieve cooling of the data center under low humidity conditions.

[0107] Case 3: Under conditions of high temperature and humidity (such as the southern region in the transition season, the northern region in summer, and the southern region in summer), the component to be cooled 20 is started. When the component to be cooled 20 is running, heat is generated, and the heat can be transferred to the first heat pipe evaporation end 10 through heat conduction. The circulating working fluid in the first heat pipe evaporation end 10 is vaporized into high-temperature steam working fluid after obtaining the heat, and the component to be cooled 20 is cooled. The high-temperature steam working fluid can be transported to the first heat pipe condensation end 30 through the pipeline.

[0108] The operation of the first fan 240 allows outdoor air to be filtered through the second filter 52. After being powered by the first fan 240, the pressure of the filtered outdoor air increases and the flow rate increases. At the same time, the collector 160 (such as a solar collector) can absorb solar energy to generate heat, and transfer the heat to the second heat pipe evaporation end 120. The circulating working medium in the second heat pipe evaporation end 120 can be vaporized into high-temperature steam working medium after obtaining heat. The high-temperature steam working medium is transported through a pipeline to the second heat pipe condensation end 130 to exchange heat with the filtered air.

[0109] The filtered outdoor air flows through the second heat pipe condensing end 130 for heat exchange, and the temperature of the filtered outdoor air rises to obtain the outdoor air after preliminary heating. At this time, the second heat pipe condensing end 130 is cooled, and the steam working medium in the second heat pipe condensing end 130 is condensed into liquid working medium. The condensed liquid working medium enters the first liquid storage tank 140 for temporary storage to provide a stable liquid working medium for the second heat pipe evaporation end 120. The liquid working medium stored in the first liquid storage tank 140 can be transported to the second heat pipe evaporation end 120 by the first refrigerant circulation pump 150.

[0110] The compressor 70 can absorb the low-temperature and low-pressure refrigerant vapor in the condensing end 30 of the first heat pipe, and convert it into high-temperature and high-pressure refrigerant vapor after compression, and then enter the condenser 100 to exchange heat with the outdoor air that has been initially heated up. The high-temperature and high-pressure refrigerant vapor is cooled, and the temperature of the outdoor air that has been initially heated up is further increased.

[0111] On the one hand, the condensed high-pressure refrigerant liquid enters the throttle valve 110, and after throttling and reducing pressure, the refrigerant liquid enters the first heat pipe condensation end 30 to absorb heat, evaporates into refrigerant vapor, and exchanges heat with the high-temperature steam working medium in the first heat pipe condensation end 30, so that the high-temperature steam working medium is initially cooled. The temperature of the high-temperature steam working medium is reduced, and part of the steam working medium is condensed into liquid working medium. The evaporated refrigerant vapor enters the compressor 70 to be compressed.

[0112] The outdoor air is filtered through the first filter 51 and dehumidified by the rotary dehumidifier before entering the modular container 26. In this way, when the air humidity is high, the dehumidified outdoor air can be used to enhance the evaporative cooling capacity. The dehumidified air flows through the first heat pipe condensation end 30 and contacts with the normal temperature circulating water sprayed by the nozzle 40. Part of the circulating water evaporates into the air, and the evaporation of the circulating water absorbs the heat of the first heat pipe condensation end 30, and the temperature of the circulating water increases. At the same time, the air also absorbs part of the heat of the first heat pipe condensation end 30, and the temperature and humidity of the air increase. The first heat pipe condensation end 30 is cooled, and the high-temperature steam working medium in the first heat pipe condensation end 30 is condensed into a low-temperature liquid working medium after receiving the cold.

[0113] The operation of the second fan 250 can put the modular container in a negative pressure state. After the heated air passes through the water baffle 210 to remove the water droplets it carries, it can be discharged into the air through the first air outlet 220. The circulating water after evaporative heat exchange can be collected by the water receiving tray 190, and after natural cooling, it is transported to the nozzle 40 through the water pump 200 and sprayed to the first heat pipe condensation end 30 to achieve indirect evaporative cooling.

[0114] The condensed low-temperature liquid working medium can enter the second liquid storage tank 170 for temporary storage to provide a stable liquid working medium for the first heat pipe evaporation end 10 . The liquid working medium stored in the second liquid storage tank 170 can be transported to the first heat pipe evaporation end 10 through the second refrigerant circulation pump 180 .

[0115] On the other hand, the outdoor air that has undergone two temperature increases can pass through the regeneration area of ​​the dehumidifier, causing the flow channel wall containing the dehumidifier in the regeneration area to be heated. The water vapor partial pressure in the dehumidifier is higher than the water vapor partial pressure of the heated outdoor air, which can drive out the moisture in the dehumidifier and realize the regeneration of the dehumidifier. The air after passing through the dehumidifier 60 has a higher humidity and can therefore be discharged into the air through the first air outlet 220.

[0116] In this way, natural cooling sources can be fully utilized to minimize energy consumption. Air dehumidification and dehumidifier regeneration modules are installed to improve the evaporative cooling capacity, and natural resources and waste heat are fully utilized to regenerate dehumidifiers, further reducing data center energy consumption.
