[0002] Data centers can be used to transmit, accelerate, display, calculate, and store data information on network infrastructure. Data centers can include electronic devices such as servers, switches, and power distribution cabinets. With the rapid development of the information and communication technology industry, the device integration and heat density of data centers are getting higher and higher, and the requirements for heat dissipation in data centers are also getting higher and higher.

[0003] To meet the heat dissipation needs of data centers, in related technologies, the cooling system of data centers often includes an air-cooled module, a liquid-cooled module, an air-cooled heat dissipation module and a liquid-cooled heat dissipation module. The air-cooled heat dissipation module is used for heat dissipation of the air-cooled module, and the liquid-cooled heat dissipation module is used for heat dissipation of the liquid-cooled module.

[0004] However, the cooling system in the related art has a complex structure and low energy efficiency. Summary of the invention

[0005] The present invention aims to provide a cooling system and a control method thereof, so as to solve the problem that the cooling system with an air cooling module and a liquid cooling module in the prior art has a relatively complex structure and low energy efficiency.

[0006] A first aspect of the present invention provides a cooling system, comprising an air cooling module, a liquid cooling module, a heat dissipation module and a first heat exchanger.

[0007] The cooling system provided by the present invention can make the cooling medium that absorbs the heat of the air cooling module flowing out from the second outlet end flow into the first heat exchange flow channel, and make the cooling medium that absorbs the heat of the liquid cooling module flowing out from the fifth outlet end flow into the second heat exchange flow channel, so that the cooling medium that absorbs the heat of the air cooling module flowing out from the second outlet end and the cooling medium that absorbs the heat of the liquid cooling module flowing out from the fifth outlet end can be combined with the cooling medium that absorbs the heat of the liquid cooling module flowing out from the fifth outlet end. Heat exchange is performed in the first heat exchanger.

In this way, the heat in the air cooling module and the liquid cooling module can be dissipated through the same heat dissipation device, which can reduce the number of heat dissipation devices that need to be set up, and can make the structure of the cooling system simpler and occupy less space. In addition, the air cooling module and the liquid cooling module share a heat dissipation device for heat dissipation, which is also conducive to improving the energy efficiency of the cooling system and the utilization rate of the cooling medium, and is conducive to reducing the energy consumption of the cooling system and the use of the cooling medium in the cooling system.

[0050] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0051] It should be noted that the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0052] In the present invention, unless otherwise clearly defined and limited, the terms "installation", "connection", "fixation" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, it can be a connection between two elements or an interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0053] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being "above", "above" or "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being "below", "below" or "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0054] In the above description, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.

[0055] The data center may include a computer room and electronic devices such as servers, switches, and power distribution cabinets located in the computer room. In order to meet the heat dissipation requirements of the data center, some electronic devices may be liquid cooling devices. In this case, the cooling system of the data center may include an air cooling module and a liquid cooling module. The air cooling module may be used to supply cold air into the computer room to cool down the electronic devices in the computer room. The liquid cooling module may include a liquid cooling device. The cooling medium in the liquid cooling module may take away the heat generated by the heating elements in the liquid cooling device to cool down the heating elements of the liquid cooling device.

[0056] Taking into account the difference in heat dissipation efficiency between the air-cooled module and the liquid-cooled module, the energy efficiency of the cooling system, the generation of condensed water at the liquid cooling device and other factors, the inlet temperature of the cooling medium used to dissipate heat in the air-cooled module is generally more than 10°C lower than the inlet temperature of the cooling medium used to dissipate heat in the liquid-cooled module. In other words, when the cooling system includes an air-cooled module and a liquid-cooled module, two cooling mediums with a temperature difference of more than 10°C need to be supplied to the air-cooled module and the liquid-cooled module, respectively. For example, in some cooling systems, a cooling medium with a temperature of 20°C to 25°C needs to be supplied to the air-cooled module, and a cooling medium with a temperature of 35°C to 45°C needs to be supplied to the liquid-cooled module.

[0057] In order to supply two cooling media with a temperature difference of more than 10°C to the air-cooled module and the liquid-cooled module, respectively, in the related art, the cooling system of the data center may also include two heat dissipation modules, the two heat dissipation modules are an air-cooled heat dissipation module and a liquid-cooled heat dissipation module, for example, the two heat dissipation modules may be a cooling tower and a chiller. The air-cooled heat dissipation module is used to supply cooling media that meets the liquid inlet requirements of the air-cooled module to the air-cooled module to dissipate heat for the air-cooled module, and the liquid-cooled heat dissipation module is used to supply cooling media that meets the liquid inlet requirements of the liquid-cooled module to the liquid-cooled module to dissipate heat for the liquid-cooled module.

[0058] However, since two heat dissipation modules are provided, two sets of pipelines and other auxiliary equipment need to be configured accordingly, which makes the structure of the cooling system more complicated and occupies a larger space. In addition, in the air-cooled heat dissipation module, energy needs to be consumed to cool the cooling medium that has absorbed the heat in the air-cooled module to a temperature that meets the liquid inlet requirements of the air-cooled module, and in the liquid-cooled heat dissipation module, energy needs to be consumed to cool the cooling medium that has absorbed the heat in the liquid-cooled module to a temperature that meets the liquid inlet requirements of the liquid-cooled module, which makes the energy efficiency of the cooling system lower. In addition, the cooling medium needs to circulate between the air-cooled module and the air-cooled heat dissipation module, and the cooling medium also needs to circulate between the liquid-cooled module and the liquid-cooled heat dissipation module. The amount of cooling medium used in the cooling system is large, and the utilization rate of the cooling medium is low.

[0059] Based on this, an embodiment of the present application provides a cooling system. By setting a heat exchanger, when the temperature of the cooling medium flowing out of the air-cooling module is lower than the required liquid inlet temperature of the cooling medium used to dissipate heat in the liquid-cooling module, the cooling medium flowing out of the air-cooling module can be heat-exchanged with the cooling medium flowing out of the liquid-cooling module in the heat exchanger, so that the heat in the liquid-cooling module can be brought to the heat dissipation device by the cooling medium flowing out of the air-cooling module for heat dissipation. The air-cooling module and the liquid-cooling module can share a heat dissipation device for heat dissipation, which can reduce the number of heat dissipation devices that need to be set up, and can make the structure of the cooling system simpler and occupy less space. In addition, the air-cooling module and the liquid-cooling module share a heat dissipation device for heat dissipation, which is also conducive to improving the energy efficiency of the cooling system and the utilization rate of the cooling medium, and is conducive to reducing the energy consumption of the cooling system and the usage of the cooling medium in the cooling system.

[0060] The following is a detailed description of an embodiment of the cooling system provided in the present application in conjunction with the accompanying drawings.

[0061] Figure 1 A schematic diagram of a cooling system proposed in an embodiment of the present application.

[0062] like Figure 1As shown, an embodiment of the present application provides a cooling system, which includes an air cooling module 100, a liquid cooling module 200, a heat dissipation module 300 and a first heat exchanger 400. The first heat exchanger 400 includes a first heat exchange channel 410 and a second heat exchange channel 420, and the first heat exchanger 400 is used to perform heat exchange between the cooling medium in the first heat exchange channel 410 and the cooling medium in the second heat exchange channel 420.

[0063] The heat dissipation module 300 includes a first inlet end 310 and a first outlet end 320, the air cooling module 100 includes a second inlet end 110 and a second outlet end 120, the first heat exchange channel 410 includes a third inlet end 411 and a third outlet end 412, the second heat exchange channel 420 includes a fourth inlet end 421 and a fourth outlet end 422, and the liquid cooling module 200 includes a fifth inlet end 210 and a fifth outlet end 220.

[0064] The first outlet port 320 is used to communicate with the second inlet port 110, the second outlet port 120 is used to communicate with the third inlet port 411, and the third outlet port 412 is used to communicate with the first inlet port 310. The fifth outlet port 220 is used to communicate with the fourth inlet port 421, and the fourth outlet port 422 is used to communicate with the fifth inlet port 210.

[0065] In this way, when the temperature of the cooling medium that absorbs the heat of the air-cooling module 100 and flows out from the second outlet port 120 is lower than the required inlet temperature of the cooling medium for dissipating heat from the liquid-cooling module 200, the cooling medium that absorbs the heat of the air-cooling module 100 and flows out from the second outlet port 120 can flow into the first heat exchange channel 410, and the cooling medium that absorbs the heat of the liquid-cooling module 200 and flows out from the fifth outlet port 220 can flow into the second heat exchange channel 420, so that the cooling medium that absorbs the heat of the air-cooling module 100 and flows out from the fifth outlet port 220 can be heated in the first heat exchanger. 400, after the cooling medium in the first heat exchange channel 410 exchanges heat with the cooling medium in the second heat exchange channel 420, the cooling medium in the first heat exchange channel 410 flows out from the third outlet port 412 and flows back to the heat dissipation module 300 for heat dissipation, and the cooling medium in the second heat exchange channel 420 flows out from the fourth outlet port 422 and flows back to the liquid cooling module 200 for absorbing the heat of the liquid cooling module 200 again. In this way, the heat in the air cooling module 100 and the liquid cooling module 200 can be dissipated through the same heat dissipation device 330, which can reduce the number of heat dissipation devices 330 that need to be set, and can make the structure of the cooling system simpler and occupy less space. In addition, the air cooling module 100 and the liquid cooling module 200 share a heat dissipation device 330 for heat dissipation, which is also conducive to improving the energy efficiency of the cooling system and the utilization rate of the cooling medium, and is conducive to reducing the energy consumption of the cooling system and the use of the cooling medium in the cooling system.

[0066] Exemplarily, the cooling medium flowing out from the first outlet port 320 may include, but is not limited to, cooling water, cooling oil, and the like.

[0067] Exemplarily, the cooling medium flowing out from the fifth outlet port 220 may include, but is not limited to, cooling water, cooling oil, and the like.

[0068] The cooling medium flowing out of the first outlet port 320 and the cooling medium flowing out of the fifth outlet port 220 may be the same or different.

[0069] In some possible implementations, a flow regulating device is connected in series between the second heat exchange channel 420 and the liquid cooling module 200 , and the flow regulating device is used to regulate the flow of the cooling medium flowing through the second heat exchange channel 420 .

[0070] In this way, when the temperature of the cooling medium that absorbs the heat of the air-cooling module 100 and flows out from the second outlet port 120 is lower than the required inlet temperature of the cooling medium for dissipating heat to the liquid-cooling module 200: if the temperature of the cooling medium that flows into the liquid-cooling module 200 from the fifth inlet port 210 is lower than the required inlet temperature of the cooling medium for dissipating heat to the liquid-cooling module 200, the flow rate of the cooling medium flowing through the second heat exchange channel 420 can be reduced by a flow regulating device to extend the time for heat exchange between the cooling medium in the second heat exchange channel 420 and the cooling medium in the first heat exchange channel 410, thereby increasing the temperature of the cooling medium that flows into the liquid-cooling module 200 from the fifth inlet port 210. If the temperature of the cooling medium flowing into the liquid cooling module 200 from the fifth inlet port 210 is higher than the required inlet temperature of the cooling medium for heat dissipation of the liquid cooling module 200, the flow rate of the cooling medium flowing through the second heat exchange channel 420 can be increased by the flow regulating device to shorten the heat exchange time between the cooling medium in the second heat exchange channel 420 and the cooling medium in the first heat exchange channel 410, thereby reducing the temperature of the cooling medium flowing into the liquid cooling module 200 from the fifth inlet port 210. In other words, when the temperature of the cooling medium flowing out from the second outlet port 120 that absorbs the heat of the air cooling module 100 is lower than the required inlet temperature of the cooling medium for heat dissipation of the liquid cooling module 200, the flow rate of the cooling medium flowing through the second heat exchange channel 420 can be adjusted by the flow regulating device to control the temperature of the cooling medium flowing into the liquid cooling module 200 from the fifth inlet port 210, so as to control the temperature of the cooling medium flowing into the liquid cooling module 200 from the fifth inlet port 210 within the required range.

[0071] In some possible implementations, a driving pump 510 is connected in series between the second heat exchange channel 420 and the liquid cooling module 200 , and the driving pump 510 is used to drive the cooling medium to flow between the liquid cooling module 200 and the second heat exchange channel 420 .

[0072] In this way, the driving pump 510 can be driven to provide the power for the cooling working fluid to flow between the liquid cooling module 200 and the second heat exchange channel 420, so that the cooling working fluid can circulate smoothly between the liquid cooling module 200 and the second heat exchange channel 420.

[0073] In some examples, the driving pump 510 is arranged between the fourth outlet end 422 and the fifth inlet end 210.

[0074] In some examples, the driving pump 510 is arranged between the fourth inlet end 421 and the fifth outlet end 220.

[0075] In some possible implementation manners, the driving pump 510 is a variable-frequency pump, and the flow regulating device of the cooling system includes the driving pump 510.

[0076] In this way, the temperature of the cooling working fluid flowing into the liquid cooling module 200 from the fifth inlet end 210 can be controlled by controlling the frequency of the driving pump 510, which is convenient for realizing the regulation of the flow rate of the cooling working fluid flowing through the second heat exchange channel 420. In addition, the frequency of the driving pump 510 can be adjusted as needed, which is more energy-saving.

[0077] Figure 2 It is a schematic diagram of another cooling system proposed in the embodiment of the present application.

[0078] As Figure 2 shown, in some possible implementation manners, a flow regulating valve 520 is connected in series between the second heat exchange channel 420 and the liquid cooling module 200. The flow regulating device of the cooling system includes the flow regulating valve 520, and the flow regulating valve 520 is used to regulate the flow rate of the cooling working fluid flowing through the second heat exchange channel 420. At this time, the driving pump 510 of the cooling system can be a fixed-frequency pump.

[0079] In this way, the flow rate of the cooling working fluid flowing through the second heat exchange channel 420 can be regulated by controlling the opening degree of the flow regulating valve 520. When the driving pump 510 needs to be set, the selection of the driving pump 510 is more diverse.

[0080] In some examples, the flow regulating valve 520 is arranged between the fourth outlet end 422 and the fifth inlet end 210.

[0081] In some examples, the flow regulating valve 520 is arranged between the fourth inlet end 421 and the fifth outlet end 220.

[0082] In some possible implementation manners, a first detection device is provided at the fifth inlet end 210, and the first detection device is used to obtain the temperature of the cooling working fluid at the fifth inlet end 210.

[0083] In this way, it is convenient to master the real-time temperature of the cooling working fluid at the fifth inlet end 210, and it is convenient to control the flow regulating device according to the real-time temperature of the cooling working fluid at the fifth inlet end 210.

[0084] Exemplarily, the flow regulating device is communicatively connected to the first detection device, and the flow regulating device is configured to adjust the flow rate of the cooling working fluid flowing through the second heat exchange channel 420 according to the temperature obtained by the first detection device.

[0085] In this way, it is convenient to realize the automatic control of the flow regulating device.

[0086] In some examples where the flow regulating device includes a driving pump 510, the driving pump 510 is communicatively connected to the first detection device, and the driving pump 510 is configured to adjust the frequency of the driving pump 510 according to the temperature obtained by the first detection device.

[0087] In some examples where the flow regulating device includes a flow regulating valve 520, the flow regulating valve 520 is communicatively connected to the first detection device, and the flow regulating valve 520 is configured to adjust the opening degree of the flow regulating valve 520 according to the temperature obtained by the first detection device.

[0088] Figure 3 It is a schematic diagram of another cooling system proposed by the embodiment of the present application.

[0089] As Figure 3 shown, in some possible implementation manners, the cooling system further includes a commutation device 530. The commutation device 530 includes a first port 531, a second port 532, and a third port 533. The second outlet end 120 is used to communicate with the first port 531, and the second port 532 is used to communicate with the third inlet end 411, so that the second outlet end 120 is used to communicate with the third inlet end 411 through the first port 531 and the second port 532. The third port 533 is used to communicate with the fifth inlet end 210, and the fifth outlet end 220 is further used to communicate with the first inlet end 310. A first valve 540 is connected in series between the second heat exchange channel 420 and the liquid cooling module 200, and a second valve 550 is connected in series between the fifth outlet end 220 and the first inlet end 310.

[0090] The commutation device 530 is configured to connect the first port 531 and the second port 532, or connect the first port 531 and the third port 533. The first valve 540 is configured to control the on-off of the flow path between the second heat exchange channel 420 and the liquid cooling module 200. The second valve 550 is configured to control the on-off of the flow path between the fifth outlet end 220 and the first inlet end 310.

[0091] It should be noted that, at this time, the cooling medium used to dissipate heat for the air cooling module 100 is the same as the cooling medium used to dissipate heat for the liquid cooling module 200, and both are cooling mediums circulating between the heat dissipation module 300 and the air cooling module 100. In other words, the cooling medium flowing out of the first outlet port 320 and the cooling medium flowing out of the fifth outlet port 220 are the same cooling medium.

[0092] In this way, when the temperature of the cooling medium that absorbs the heat of the air-cooling module 100 and flows out from the second outlet port 120 is lower than the required liquid inlet temperature of the cooling medium for dissipating heat from the liquid-cooling module 200, the first port 531 can be connected to the second port 532, the first valve 540 can be opened, and the second valve 550 can be closed, so that the cooling medium that absorbs the heat of the air-cooling module 100 and flows out from the second outlet port 120 can flow through the first heat exchange channel 410 and then flow to the first inlet port 310, and the cooling medium that absorbs the heat of the liquid-cooling module 200 and flows out from the fifth outlet port 220 can flow through the second heat exchange channel 420 and then flow to the fifth inlet port 210. When the temperature of the cooling medium that absorbs the heat of the air-cooling module 100 and flows out from the second outlet port 120 meets the required liquid inlet temperature of the cooling medium for dissipating heat to the liquid-cooling module 200, the first port 531 can be connected to the third port 533, the first valve 540 is closed, and the second valve 550 is opened, so that at least part of the cooling medium that absorbs the heat of the air-cooling module 100 and flows out from the second outlet port 120 flows to the fifth inlet port 210 to absorb the heat of the liquid-cooling module 200, and the cooling medium that flows out from the fifth outlet port 220 flows to the first inlet port 310 to dissipate the heat of the cooling medium that absorbs the heat of the liquid-cooling module 200 and the air-cooling module 100 through the heat dissipation device 330. In this way, when the temperature of the cooling medium that has absorbed the heat of the air cooling module 100 and flows out from the second outlet port 120 is lower than the required liquid inlet temperature of the cooling medium for dissipating heat to the liquid cooling module 200, and when the temperature of the cooling medium that has absorbed the heat of the air cooling module 100 and flows out from the second outlet port 120 meets the required liquid inlet temperature of the cooling medium for dissipating heat to the liquid cooling module 200, the heat in the air cooling module 100 and the liquid cooling module 200 can be dissipated through the same heat dissipation device 330. In addition, different working modes can be switched by controlling the reversing device 530, the first valve 540 and the second valve 550 to adapt to different liquid outlet temperatures of the air cooling module 100, so that the air cooling module 100 and the liquid cooling module 200 that dissipate heat through the same heat dissipation module 300 have higher heat dissipation efficiency at different liquid outlet temperatures of the air cooling module 100.

[0093] Exemplarily, the reversing device 530 may be a three-way reversing valve, and the three ports of the three-way reversing valve are respectively a first port 531 , a second port 532 , and a third port 533 .

[0094] Exemplarily, the reversing device 530 may include a third valve, a fourth valve and a connecting pipe, one end of the connecting pipe is a first port 531, the other end of the connecting pipe is connected to one end of the third valve and one end of the fourth valve, the other end of the third valve is a second port 532, and the other end of the fourth valve is a third port 533.

[0095] In some examples, the first valve 540 may be an on-off valve.

[0096] In some examples, the first valve 540 may be the flow regulating valve 520 . In this case, the flow regulating device may include the first valve 540 .

[0097] Exemplarily, the second valve 550 may be a switch valve or a flow valve.

[0098] Exemplarily, the reversing device 530 can be used to control the opening of the flow channel between the first port 531 and the second port 532 and to control the opening of the flow channel between the first port 531 and the third port 533. That is, the reversing device 530 can be used to partially open the flow channel between the first port 531 and the second port 532 and partially open the flow channel between the first port 531 and the third port 533, or to fully open the flow channel between the first port 531 and the second port 532 and disconnect the flow channel between the first port 531 and the third port 533, or to disconnect the self-test flow channel between the first port 531 and the second port 532 and fully open the flow channel between the first port 531 and the third port 533.

[0099] In some possible implementations, the cooling system further includes a first pipeline 610, a second pipeline 620, a third pipeline 630, a fourth pipeline 640, and a fifth pipeline 650. One end of the first pipeline 610 is in communication with the third port 533, and the other end of the first pipeline 610 is in communication with the fifth inlet port 210. One end of the second pipeline 620 is in communication with the fourth outlet port 422, and the other end of the second pipeline 620 is in communication with the first pipeline 610. One end of the third pipeline 630 is in communication with the third outlet port 412, and the other end of the third pipeline 630 is in communication with the first inlet port 310. One end of the fourth pipeline 640 is in communication with the fifth outlet port 220, and the other end of the fourth pipeline 640 is in communication with the third pipeline 630. One end of the fifth pipeline 650 is in communication with the fourth inlet port 421, and the other end of the fifth pipeline 650 is in communication with the fourth pipeline 640. A first valve 540 is provided on at least one of the second pipeline 620 and the fifth pipeline 650. The fourth pipeline 640 is provided with a second valve 550 , and the second valve 550 is located between one end of the fifth pipeline 650 connected to the fourth pipeline 640 and one end of the fourth pipeline 640 connected to the third pipeline 630 .

[0100] In this way, the pipelines in the cooling system are relatively simple, which can make the cooling system more integrated and occupy less space.

[0101] In an example where the cooling system includes the driving pump 510 , the driving pump 510 may be disposed on the second line 620 or the fifth line 650 .

[0102] In some possible implementations, the second outlet port 120 is provided with a second detection device, and the second detection device is used to obtain the temperature of the cooling medium at the second outlet port 120 .

[0103] In this way, it is convenient to grasp the real-time temperature of the cooling medium at the second outlet port 120 , and to control the reversing device 530 , the first valve 540 and the second valve 550 according to the real-time temperature of the cooling medium at the second outlet port 120 .

[0104] Exemplarily, the reversing device 530, the first valve 540 and the second valve 550 are all communicatively connected to the second detection device, the reversing device 530 is used to control the connection between the first port 531 and the second port 532, or the connection between the first port 531 and the third port 533 according to the temperature detected by the second detection device, the first valve 540 is used to control the on-off of the flow path between the second heat exchange channel 420 and the liquid cooling module 200 according to the temperature detected by the second detection device, and the second valve 550 is used to control the on-off of the flow path between the fifth outlet port 220 and the first inlet port 310 according to the temperature detected by the second detection device.

[0105] In this way, it is easy to realize automatic control of the reversing device 530 , the first valve 540 and the second valve 550 .

[0106] In some possible implementations, the heat dissipation module 300 includes a heat dissipation device 330 , and the heat dissipation device 330 includes a first inlet port 310 and a first outlet port 320 .

[0107] Figure 4 This is a schematic diagram of another cooling system proposed in an embodiment of the present application.

[0108] like Figure 4 As shown, in some possible implementations, the heat dissipation module 300 includes a heat dissipation device 330 and a cold source distribution device 340. The cold source distribution device 340 includes a third heat exchange channel 341 and a fourth heat exchange channel 342, and the cold source distribution device 340 is used to make the cooling medium in the third heat exchange channel 341 and the cooling medium in the fourth heat exchange channel 342 perform heat exchange. The third heat exchange channel 341 includes a first inlet end 310 and a first outlet end 320. The outlet end of the fourth heat exchange channel 342 is used to communicate with the inlet end of the heat dissipation device 330, and the inlet end of the fourth heat exchange channel 342 is used to communicate with the outlet end of the heat dissipation device 330.

[0109] In this way, the cold source distribution device 340 can be used to provide power to the cooling medium circulating in the air-cooling module 100 and the third heat exchange channel 341, which can reduce the setting of the driving device. In addition, the cooling medium circulating in the air-cooling module 100 and the third heat exchange channel 341 is isolated from the cooling medium circulating between the fourth heat exchange channel 342 and the heat sink 330, which can reduce the use of the cooling medium that needs to flow through the air-cooling module 100 and the liquid-cooling module 200 with higher standard requirements, and reduce the risk of the cooling medium circulating between the fourth heat exchange channel 342 and the heat sink 330 contaminating the cooling medium flowing through the air-cooling module 100 and the liquid-cooling module 200.

[0110] Exemplarily, the cooling medium circulating between the fourth heat exchange channel 342 and the heat dissipation device 330 may include, but is not limited to, cooling water, coolant, etc.

[0111] Exemplarily, the cooling medium circulating between the fourth heat exchange channel 342 and the heat sink 330 may be the same as or different from the cooling medium circulating in the air cooling module 100 and the third heat exchange channel 341. When the cooling medium circulating between the fourth heat exchange channel 342 and the heat sink 330 may be the same as the cooling medium circulating in the air cooling module 100 and the third heat exchange channel 341, the cooling medium circulating between the fourth heat exchange channel 342 and the heat sink 330 may be different from the cooling medium circulating in the air cooling module 100 and the third heat exchange channel 341 according to standard requirements.

[0112] Exemplarily, the heat dissipation device 330 may include but is not limited to a cooling tower, a chiller, and the like.

[0113] Figure 5 A schematic diagram of an air cooling module of a cooling system proposed in an embodiment of the present application.

[0114] like Figure 5 As shown, in some possible embodiments, the air cooling module 100 includes a compressor 130, a condenser 140 and an evaporator 150. The condenser 140 includes a fifth heat exchange channel 141 and a sixth heat exchange channel 142, and the condenser 140 is used to make the cooling medium in the fifth heat exchange channel 141 and the cooling medium in the sixth heat exchange channel 142 perform heat exchange. The fifth heat exchange channel 141 includes a second inlet end 110 and a second outlet end 120. The outlet end of the compressor 130 is used to communicate with the inlet end of the sixth heat exchange channel 142, and the outlet end of the sixth heat exchange channel 142 is used to communicate with the inlet end of the evaporator 150, and the outlet end of the evaporator 150 is used to communicate with the inlet end of the compressor 130.

[0115] In this way, the cooling medium flowing through the fifth heat exchange channel 141 is isolated from the cooling medium circulating between the compressor 130, the sixth heat exchange channel 142 and the evaporator 150, which can reduce the usage of the cooling medium circulating between the compressor 130, the sixth heat exchange channel 142 and the evaporator 150 with higher standards, and can reduce the risk of the cooling medium flowing through the fifth heat exchange channel 141 contaminating the cooling medium circulating between the compressor 130, the sixth heat exchange channel 142 and the evaporator 150.

[0116] Exemplarily, the cooling medium circulating between the compressor 130 , the sixth heat exchange channel 142 , and the evaporator 150 may include, but is not limited to, cooling water, fluorinated liquid, cooling oil, and the like.

[0117] Exemplarily, the cooling medium circulating between the compressor 130 , the sixth heat exchange channel 142 , and the evaporator 150 and the cooling medium flowing through the fifth heat exchange channel 141 are different cooling mediums.

[0118] In an example where the air cooling module 100 includes the compressor 130 , the condenser 140 , and the evaporator 150 , the air cooling module 100 further includes a fan, which is disposed at the evaporator 150 and blows air toward the evaporator 150 .

[0119] like Figure 4 As shown, in some possible implementations, the liquid cooling module 200 includes a liquid cooling device 240, and the liquid cooling device 240 may include a fifth inlet port 210 and a fifth outlet port 220. At this time, the cooling medium circulating between the air cooling module 100 and the heat dissipation module 300 and the cooling medium flowing through the liquid cooling device 240 are the same cooling medium.

[0120] In this way, the structure of the cooling system can be made simpler, and the types and amounts of cooling media used in the cooling system can be reduced.

[0121] Figure 6 A schematic diagram of a liquid cooling module of a cooling system proposed in an embodiment of the present application.

[0122] like Figure 6 As shown, in some possible embodiments, the liquid cooling module 200 includes a second heat exchanger 230 and a liquid cooling device 240. The second heat exchanger 230 includes a seventh heat exchange channel 231 and an eighth heat exchange channel 232, and the second heat exchanger 230 is used to exchange heat between the cooling medium in the seventh heat exchange channel 231 and the cooling medium in the eighth heat exchange channel 232. The seventh heat exchange channel 231 includes a fifth inlet end 210 and a fifth outlet end 220. The outlet end of the eighth heat exchange channel 232 is used to communicate with the inlet end of the liquid cooling device 240, and the inlet end of the eighth heat exchange channel 232 is used to communicate with the outlet end of the liquid cooling device 240.

[0123] In this way, the cooling medium flowing through the seventh heat exchange channel 231 and the cooling medium flowing through the liquid cooling device 240 are isolated from each other, so that the cooling medium flowing through the liquid cooling device 240 and the cooling medium flowing through the seventh heat exchange channel 231 can be different cooling mediums, which can reduce the usage of the cooling medium flowing through the liquid cooling device 240 with higher standard requirements, and reduce the risk of the cooling medium flowing through the seventh heat exchange channel 231 contaminating the cooling medium flowing through the liquid cooling device 240.

[0124] Exemplarily, the cooling medium flowing through the liquid cooling device 240 may be a single-phase cooling medium or a two-phase cooling medium. For example, the cooling medium flowing through the liquid cooling device 240 may be a fluoride.

[0125] Exemplarily, the liquid cooling device 240 may include, but is not limited to, a liquid cooling server, a liquid cooling cabinet, and the like.

[0126] Exemplarily, the liquid cooling device 240 may be an immersion liquid cooling device.

[0127] Exemplarily, the liquid cooling device 240 may be a cold plate type liquid cooling device.

[0128] Figure 7 This is a flow chart of a method for controlling a cooling system proposed in an embodiment of the present application.

[0129] like Figure 7 As shown, and see Figure 3 , an embodiment of the present application also provides a method for controlling a cooling system, which is used to control the cooling system in any of the above-mentioned embodiments.

[0130] The cooling system has a first working mode. When the cooling system is in the first working mode, the cooling medium flowing out from the second outlet port 120 flows to the first inlet port 310 after passing through the first heat exchange channel 410, and the cooling medium flowing out from the fifth outlet port 220 flows to the fifth inlet port 210 after passing through the second heat exchange channel 420.

[0131] Specifically, in the example where the cooling system includes the reversing device 530, the first valve 540, and the second valve 550, when the cooling system is in the first working mode, the first port 531 is connected to the second port 532, the first valve 540 is opened, the second valve 550 is closed, and the driving pump 510 is turned on. The cooling medium in the liquid cooling module 200 can circulate between the liquid cooling module 200 and the second heat exchange flow channel 420 under the drive of the driving pump 510. The cooling medium flowing out from the first outlet port 320 flows through the air cooling module 100, enters the first heat exchange channel 410, and exchanges heat with the cooling medium in the second heat exchange channel 420 in the first heat exchange channel 410. The temperature of the cooling medium in the first heat exchange channel 410 that absorbs the heat of the air cooling module 100 is lower than the temperature of the cooling medium in the second heat exchange channel 420 that absorbs the heat of the liquid cooling module 200. After absorbing the heat of the cooling medium in the second heat exchange channel 420, the cooling medium in the first heat exchange channel 410 flows back to the heat dissipation module 300 for heat dissipation, and then flows out from the first outlet port 320. That is to say, when the cooling system is in the first working mode, the cooling medium flowing out from the first outlet port 320 circulates between the heat dissipation module 300, the air cooling module 100 and the first heat exchange channel 410, and the cooling medium flowing out from the fifth outlet port 220 circulates between the second heat exchange channel 420 and the liquid cooling module 200, and the heat generated by the liquid cooling module 200 is carried away by the cooling medium flowing through the first heat exchange channel 410.

[0132] The control method includes:

[0133] S100: Obtaining a first temperature, wherein the first temperature is the temperature of the cooling medium at the second outlet 120 .

[0134] Exemplarily, the first temperature can be acquired by a second detection device.

[0135] S200: When the first temperature is less than a first threshold, the cooling system is controlled to operate in a first working mode, wherein the first threshold is a preset lower limit of the temperature of the cooling medium flowing into the fifth inlet port 210 .

[0136] In this way, when the temperature of the cooling medium flowing out of the second outlet port 120 is lower than the preset lower limit value of the temperature of the cooling medium flowing into the fifth inlet port 210, the heat in the air-cooled module 100 and the liquid-cooled module 200 can be dissipated through the same heat sink 330, which can reduce the number of heat sinks 330 that need to be set, and can make the structure of the cooling system simpler and occupy less space. In addition, the air-cooled module 100 and the liquid-cooled module 200 share a heat sink 330 for heat dissipation, which is also conducive to improving the energy efficiency of the cooling system and the utilization rate of the cooling medium, and is conducive to reducing the energy consumption of the cooling system and the amount of cooling medium used in the cooling system.

[0137] In some possible implementations, the control method further includes:

[0138] S210: When the cooling system operates in the first working mode, a second temperature is obtained, wherein the second temperature is the temperature of the cooling medium at the fifth inlet port 210 .

[0139] Exemplarily, the second temperature can be acquired by the first detection device.

[0140] S220 : When the second temperature is lower than the first threshold, the flow regulating device is controlled to reduce the flow of the cooling medium flowing through the second heat exchange flow channel 420 .

[0141] In this way, when the temperature of the cooling medium that absorbs the heat of the air-cooling module 100 and flows out from the second outlet port 120 is lower than the preset lower limit value of the temperature of the cooling medium flowing into the fifth inlet port 210, the flow rate of the cooling medium flowing through the second heat exchange channel 420 can be reduced by controlling the flow regulating device to extend the time for heat exchange between the cooling medium in the second heat exchange channel 420 and the cooling medium in the first heat exchange channel 410, thereby increasing the temperature of the cooling medium flowing into the liquid cooling module 200 from the fifth inlet port 210, thereby facilitating controlling the temperature of the cooling medium flowing into the liquid cooling module 200 from the fifth inlet port 210 within the required range.

[0142] The first threshold value can be set according to actual conditions. For example, the first threshold value can be set to 35° C., 36° C., 37° C., 38° C., 39° C., 40° C., etc.

[0143] Exemplarily, when the flow regulating device includes a driving pump 510, and the driving pump 510 is a variable frequency pump, the flow of the cooling medium flowing through the second heat exchange flow channel 420 can be reduced by reducing the frequency of the driving pump 510. That is, step S220 may include: when the second temperature is less than the first threshold, controlling the driving pump 510 to reduce the frequency of operation.

[0144] For example, when the flow regulating device includes a flow regulating valve 520, the flow of the cooling medium flowing through the second heat exchange flow channel 420 can be reduced by reducing the opening of the flow regulating valve 520. That is, step S220 may include: when the second temperature is less than the first threshold, controlling the flow regulating valve 520 to reduce the opening.

[0145] In some possible implementations, the control method further includes:

[0146] S230: When the second temperature is greater than the second threshold, the flow regulating device is controlled to increase the flow of the cooling medium flowing through the second heat exchange flow channel 420. The second threshold is a preset upper limit value of the temperature of the cooling medium flowing into the fifth inlet port 210.

[0147] In this way, when the temperature of the cooling medium that absorbs the heat of the air-cooling module 100 and flows out from the second outlet port 120 is higher than the preset upper limit value of the temperature of the cooling medium flowing into the fifth inlet port 210, the flow rate of the cooling medium flowing through the second heat exchange channel 420 can be increased by controlling the flow regulating device to shorten the time for heat exchange between the cooling medium in the second heat exchange channel 420 and the cooling medium in the first heat exchange channel 410, thereby reducing the temperature of the cooling medium flowing into the liquid cooling module 200 from the fifth inlet port 210, thereby facilitating controlling the temperature of the cooling medium flowing into the liquid cooling module 200 from the fifth inlet port 210 within the required range.

[0148] The second threshold value can be set according to actual conditions. For example, the second threshold value can be set to 43° C., 44° C., 45° C., 46° C., 47° C., etc.

[0149] Exemplarily, when the flow regulating device includes a driving pump 510, and the driving pump 510 is a variable frequency pump, the flow of the cooling medium flowing through the second heat exchange flow channel 420 can be increased by increasing the frequency of the driving pump 510. That is, step S220 may include: when the second temperature is greater than the second threshold, controlling the driving pump 510 to increase the frequency of operation.

[0150] For example, when the flow regulating device includes a flow regulating valve 520, the flow of the cooling medium flowing through the second heat exchange flow channel 420 can be increased by increasing the opening of the flow regulating valve 520. That is, step S220 may include: when the second temperature is greater than the second threshold, controlling the flow regulating valve 520 to increase the opening.

[0151] In some possible implementations, the cooling system further has a second working mode. When the cooling system is in the second working mode, the first port 531 is connected to the third port 533, the first valve 540 is closed, and the second valve 550 is opened. At least part of the cooling medium flowing out of the second outlet port 120 flows to the fifth inlet port 210, and the cooling medium flowing out of the fifth outlet port 220 flows to the first inlet port 310. That is, after the cooling medium flowing out of the first outlet port 320 passes through the air cooling module 100 and absorbs the heat of the air cooling module 100, at least part of it flows to the liquid cooling module 200. After passing through the liquid cooling module 200 and absorbing the heat of the liquid cooling module 200, the cooling medium flows back to the heat dissipation module 300 for heat dissipation, and then flows out from the first outlet port 320. In other words, when the cooling system is in the second working mode, at least part of the cooling medium flowing out from the first outlet port 320 circulates among the heat dissipation module 300, the air cooling module 100, and the liquid cooling module 200. After the cooling medium flowing out from the first outlet port 320 absorbs the heat of the air cooling module 100, at least part of it is used to flow to the liquid cooling module 200 to take away the heat of the liquid cooling module 200.

[0152] The control method also includes:

[0153] S300: When the first temperature is greater than or equal to a first threshold and less than or equal to a second threshold, controlling the cooling system to operate in a second operating mode.

[0154] In this way, when the temperature of the cooling medium that absorbs the heat of the air-cooling module 100 and flows out from the second outlet port 120 meets the required liquid inlet temperature of the cooling medium for dissipating heat from the liquid-cooling module 200, the heat in both the air-cooling module 100 and the liquid-cooling module 200 can be dissipated through the same heat dissipation device 330.

[0155] Exemplarily, when the cooling system is in the second working mode, the flow channel between the first port 531 and the second port 532 is disconnected, and at least part of the cooling medium flowing out of the second outlet port 120 flows to the fifth inlet port 210 .

[0156] Exemplarily, when the cooling system is in the second operating mode, the flow channel between the first port 531 and the second port 532 is partially opened, the flow channel between the first port 531 and the third port 533 is partially opened, and part of the cooling medium flowing out from the second outlet port 120 flows to the fifth inlet port 210 and part flows to the third inlet port 411.

[0157] Figure 8 A schematic diagram of a control device for a cooling system proposed in an embodiment of the present application.

[0158] like Figure 8 As shown, and see Figure 3 An embodiment of the present application also provides a control device for a cooling system, including various functional modules for implementing the control method in any of the above-mentioned embodiments.

[0159] Specifically, the control device includes an acquisition module 710 and a first control module 720 .

[0160] The acquisition module 710 is used to acquire a first temperature, wherein the first temperature is the temperature of the cooling medium at the second outlet 120 .

[0161] The first control module 720 is used to control the cooling system to operate in a first working mode when the first temperature is less than a first threshold value, wherein the first threshold value is a preset lower limit value of the temperature of the cooling medium flowing into the fifth inlet port 210 .

[0162] In some possible implementations, the first control module 720 includes an acquisition unit and a first control unit.

[0163] The acquisition unit is used to acquire the second temperature when the cooling system operates in the first working mode, wherein the second temperature is the temperature of the cooling medium at the fifth inlet port 210 .

[0164] The first control unit is used to control the flow regulating device to reduce the flow of the cooling medium flowing through the second heat exchange channel 420 when the second temperature is less than the first threshold value.

[0165] In some possible implementations, the first control module 720 also includes a second control unit.

[0166] The second control unit is used to control the flow regulating device to increase the flow of the cooling medium flowing through the second heat exchange flow channel 420 when the second temperature is greater than the second threshold value. The second threshold value is a preset upper limit value of the temperature of the cooling medium flowing into the fifth inlet port 210.
