Description

Technical Field

[0001] The present invention relates to the technical field of servers, and in particular to a server cooling system and a control method and device thereof. Background Art

[0002] Internet service providers, enterprise platforms, research institutions, etc. all have a large number of computing needs. The operating platform that carries storage, computing, and network needs is called a data center. A data center can include a computer room and servers located in the computer room. With the rapid development of the information and communication technology industry, the integration and heat density of servers in data centers are getting higher and higher, and the requirements for server heat dissipation are also getting higher and higher.

[0003] In order to improve the heat dissipation performance of the server, in the related technology, the server in the data center can adopt a liquid-cooled server, that is, a cooling medium can be injected into the liquid-cooled server, and the cooling medium can absorb the heat generated by the liquid-cooled server. The liquid-cooled server can form a circulation loop with the cooling tower heat dissipation module connected in series, and the cooling medium can circulate in the circulation loop. After the cooling medium that absorbs the heat generated by the liquid-cooled server flows along the circulation loop to the cooling tower heat dissipation module, the cooling tower heat dissipation module can take away the heat in the cooling medium to dissipate the heat generated by the liquid-cooled server outside the computer room.

[0004] However, in the related art, the heat dissipation mode of the liquid-cooled server is single and the energy waste is relatively serious. Summary of the invention

[0005] The present invention aims to provide a server cooling system and a control method and device thereof, so as to solve the problem that the liquid cooling server in the prior art has a single heat dissipation mode and serious energy waste.

[0006] On one hand, the present invention provides a server cooling system, including a liquid-cooled server, a first flow regulating device, a cooling tower heat dissipation module, and a hot water module. The cooling tower heat dissipation module and the hot water module are arranged in parallel, and the inlet ends of the cooling tower heat dissipation module and the hot water module are both connected to the outlet end of the liquid-cooled server, and the outlet ends of the cooling tower heat dissipation module and the hot water module are both connected to the inlet end of the liquid-cooled server. Among them, the inlet end of at least one of the cooling tower heat dissipation module and the hot water module is connected to the outlet end of the liquid-cooled server through the first flow regulating device. The first flow regulating device is used to regulate the flow of the first cooling medium flowing through the cooling tower heat dissipation module and the hot water module.

[0007] In the server cooling system provided by the present invention, the first flow regulating device can distribute the first cooling medium flowing to the hot water module and the cooling tower heat dissipation module. When the user has a demand for hot water, the first flow regulating device can be controlled to allow the first cooling medium that has at least partially absorbed the heat of the liquid-cooled server to flow to the hot water module for heat exchange, so as to heat the water in the hot water module. When the user does not have a demand for hot water, the first flow regulating device can be controlled to allow the first cooling medium to flow to the cooling tower heat dissipation module for heat dissipation, and the liquid-cooled server can dissipate heat through a variety of heat dissipation modes. In addition, when the liquid-cooled server dissipates heat through the hot water module, the heat generated by the liquid-cooled server can be recycled and utilized through the first cooling medium flowing to the hot water module, which is beneficial to improving the energy utilization rate of the server cooling system. In addition, when the liquid-cooled server dissipates heat through the hot water module, after the first cooling medium that has at least partially absorbed the heat of the liquid-cooled server flows to the hot water module, only part of the first cooling medium that has absorbed the heat of the liquid-cooled server flows to the cooling tower heat dissipation module, or no longer flows. The amount of the first cooling medium that needs to be cooled by the cooling tower heat dissipation module becomes less, or no first cooling medium needs to be cooled by the cooling tower heat dissipation module, which can reduce the energy consumption of the cooling tower heat dissipation module and make the energy consumption of the server cooling system lower.

When the liquid-cooled server 1 is an immersion liquid-cooled server, the first cooling medium can be contained in the shell of the immersion liquid-cooled server, the inlet end of the shell is the inlet end of the liquid-cooled server 1, and the outlet end of the shell is the outlet end of the liquid-cooled server 1.

[0108] In the related art, the liquid-cooled server and the cooling tower heat dissipation module constitute the server cooling system. That is to say, in addition to the cooling tower heat dissipation module, there is no other module in the server cooling system that can be used to exchange heat with the first cooling medium that absorbs the heat in the liquid-cooled server. The heat generated by the liquid-cooled server can only be dissipated through the cooling tower heat dissipation module, which consumes a large amount of cooling water, electricity and other energy. The heat generated by the liquid-cooled server cannot be recycled according to user needs. The heat dissipation mode of the liquid-cooled server is single and the energy waste is relatively serious.

[0109] like Figure 1 As shown, based on this, in the embodiment of the present disclosure, the server cooling system also includes a first flow regulating device and a hot water module 2. The cooling tower heat dissipation module 3 and the hot water module 2 are arranged in parallel, and the inlet ends of the cooling tower heat dissipation module 3 and the hot water module 2 are both connected to the outlet end of the liquid-cooled server 1, and the outlet ends of the cooling tower heat dissipation module 3 and the hot water module 2 are both connected to the inlet end of the liquid-cooled server 1. Among them, the inlet end of at least one of the cooling tower heat dissipation module 3 and the hot water module 2 is connected to the outlet end of the liquid-cooled server 1 through the first flow regulating device. The first flow regulating device is used to adjust the flow of the first cooling medium flowing through the cooling tower heat dissipation module 3 and the hot water module 2.

[0110] In this way, the first flow regulating device can distribute the first cooling medium flowing to the hot water module 2 and the cooling tower heat dissipation module 3. When the user has a hot water demand, the first flow regulating device can be controlled to make the first cooling medium that has at least partially absorbed the heat of the liquid-cooled server 1 flow to the hot water module 2 for heat exchange to heat the water in the hot water module 2. When the user does not have a hot water demand, the first flow regulating device can be controlled to make the first cooling medium flow to the cooling tower heat dissipation module 3 for heat dissipation, and the liquid-cooled server 1 can dissipate heat through a variety of heat dissipation modes. In addition, when the liquid-cooled server 1 dissipates heat through the hot water module 2, the heat generated by the liquid-cooled server 1 can be recycled and utilized through the first cooling medium flowing to the hot water module 2, which is beneficial to improving the energy utilization rate of the server cooling system. In addition, when the liquid-cooled server 1 dissipates heat through the hot water module 2, after the first cooling medium that has at least partially absorbed the heat of the liquid-cooled server 1 flows to the hot water module 2, only part of the first cooling medium that has absorbed the heat of the liquid-cooled server 1 flows to the cooling tower heat dissipation module 3, or no longer flows. The amount of the first cooling medium that needs to be cooled by the cooling tower heat dissipation module 3 becomes less, or no first cooling medium needs to be cooled by the cooling tower heat dissipation module 3, which can reduce the energy consumption of the cooling tower heat dissipation module 3 and make the energy consumption of the server cooling system lower.

[0111] It is understandable that when the liquid cooling server 1 is an immersion liquid cooling server, the first cooling medium is an insulating cooling medium. Exemplarily, the first cooling medium may be fluoride.

[0112] It can be understood that the first flow regulating device can connect the inlet end of the hot water module 2 with the outlet end of the liquid cooling server 1, and connect the inlet end of the cooling tower heat dissipation module 3 with the outlet end of the liquid cooling server 1. At this time, part of the first cooling medium that absorbs the heat generated by the liquid cooling server 1 flows to the hot water module 2 for heat exchange, and part flows to the cooling tower heat dissipation module 3 for heat dissipation.

[0113] Alternatively, the first flow regulating device can connect the inlet end of the hot water module 2 with the outlet end of the liquid cooling server 1 and disconnect the inlet end of the cooling tower heat dissipation module 3 with the outlet end of the liquid cooling server 1. At this time, the first cooling medium that has absorbed the heat generated by the liquid cooling server 1 flows to the hot water module 2 for heat exchange, and a circulation loop is formed between the liquid cooling server 1 and the hot water module 2.

[0114] Alternatively, the first flow regulating device can also disconnect the inlet end of the hot water module 2 from the outlet end of the liquid cooling server 1 and connect the inlet end of the cooling tower heat dissipation module 3 with the outlet end of the liquid cooling server 1. At this time, the first cooling medium that absorbs the heat generated by the liquid cooling server 1 flows to the cooling tower heat dissipation module 3 for heat dissipation, and a circulation loop is formed between the liquid cooling server 1 and the cooling tower heat dissipation module 3.

[0115] In some examples, the first flow regulating device can also disconnect the inlet end of the hot water module 2 from the outlet end of the liquid cooling server 1, and disconnect the inlet end of the cooling tower heat dissipation module 3 from the outlet end of the liquid cooling server 1. At this time, the first cooling medium neither flows to the cooling tower heat dissipation module 3 nor flows to the hot water module 2, and the first cooling medium can stop circulating.

[0116] Figure 2 This is a schematic diagram of a server cooling system in a first hot water production state according to an embodiment of the present disclosure. Figure 3 This is a schematic diagram of a server cooling system proposed in an embodiment of the present disclosure in a second hot water production condition.

[0117] like Figure 2 , Figure 3 As shown, the server cooling system of the present invention has a hot water making mode, and the hot water making module 2 includes a first hot water making state. When the server cooling system is in the first hot water making state, the outlet end of the liquid-cooled server 1 is connected to the inlet end of the hot water making module 2, and the first cooling medium flowing out of the liquid-cooled server 1 of the server cooling system at least partially flows through the hot water making module 2, and the hot water making module 2 absorbs heat in the first cooling medium flowing therethrough to prepare hot water.

[0118] like Figure 2 As shown, the first hot water making state includes the first hot water making condition. When the server cooling system is in the first hot water making condition, the outlet end of the liquid-cooled server 1 is connected to the inlet end of the cooling tower heat dissipation module 3, and the first cooling medium partially flows through the hot water making module 2 and partially flows through the cooling tower heat dissipation module 3 of the server cooling system. The cooling tower heat dissipation module 3 is in operation, and the first cooling medium flowing through the cooling tower heat dissipation module 3 dissipates heat through the cooling tower heat dissipation module 3, that is, the first cooling medium that absorbs the heat in the liquid-cooled server 1 partially prepares hot water through the hot water making module 2 and partially dissipates heat through the cooling tower heat dissipation module 3.

[0119] like Figure 3As shown, the first hot water making state also includes the second hot water making condition. When the server cooling system is in the second hot water making condition, the outlet end of the liquid cooling server 1 is disconnected from the inlet end of the cooling tower heat dissipation module 3, and the first cooling medium flows through the hot water making module 2, that is, the first cooling medium that absorbs the heat in the liquid cooling server 1 is used to prepare hot water through the hot water making module 2.

[0120] In one feasible manner, the first flow regulating device includes a first two-way valve, the inlet end of the cooling tower heat dissipation module 3 is connected to the outlet end of the liquid cooling server 1 through the first two-way valve, and the hot water module 2 is connected in parallel with the whole formed by the cooling tower heat dissipation module 3 and the first two-way valve, that is, the inlet end of the first two-way valve is connected between the inlet end of the hot water module 2 and the outlet end of the liquid cooling server 1, and the first two-way valve is used to regulate the flow of the first cooling medium flowing through the cooling tower heat dissipation module 3 so as to regulate the flow of the first cooling medium flowing through the hot water module 2.

[0121] In one feasible manner, the first flow regulating device includes a second two-way valve, the inlet end of the hot water module 2 is connected to the outlet end of the liquid cooling server 1 through the second two-way valve, and the cooling tower heat dissipation module 3 is connected in parallel with the hot water module 2 and the second two-way valve as a whole, that is, the inlet end of the second two-way valve is connected between the inlet end of the cooling tower heat dissipation module 3 and the outlet end of the liquid cooling server 1, and the second two-way valve is used to regulate the flow of the first cooling medium flowing through the hot water module 2 so as to regulate the flow of the first cooling medium flowing through the cooling tower heat dissipation module 3.

[0122] like Figure 1 As shown, in one achievable manner, the first flow regulating device includes a first three-way valve 4, and the inlet ends of the cooling tower heat dissipation module 3 and the hot water module 2 are both connected to the outlet end of the liquid cooling server 1 through the first three-way valve 4. The first three-way valve 4 is used to regulate the flow of the first cooling medium flowing through the cooling tower heat dissipation module 3 and the hot water module 2.

[0123] In this way, the connection between the inlet end of the hot water module 2 and the cooling tower heat dissipation module 3 and the outlet end of the liquid cooling server 1 is more convenient. In addition, it is convenient to adjust the flow rate of the first cooling medium flowing through the hot water module 2 and the cooling tower heat dissipation module 3 by adjusting the opening of the two ports connected to the inlet end of the hot water module 2 and the cooling tower heat dissipation module 3 of the first three-way valve 4, and the flow rate regulation is more accurate.

[0124] In some examples, the first three-way valve 4 can independently adjust the flow of the first cooling medium flowing through the hot water module 2 and the cooling tower heat dissipation module 3, that is, the first three-way valve 4 can independently adjust the opening of the two ports connected to the inlet ends of the hot water module 2 and the cooling tower heat dissipation module 3. In this way, the two ports of the first three-way valve 4 connected to the inlet ends of the hot water module 2 and the cooling tower heat dissipation module 3 can be closed, and the inlet ends of the hot water module 2 and the cooling tower heat dissipation module 3 are disconnected from the outlet end of the liquid cooling server 1.

[0125] In one feasible manner, the server cooling system also includes a second flow regulating device, and the outlet end of at least one of the cooling tower heat dissipation module 3 and the hot water module 2 is connected to the inlet end of the liquid cooling server 1 through the second flow regulating device, and the second flow regulating device is used to regulate the flow of the first cooling medium flowing through the cooling tower heat dissipation module 3 and the hot water module 2.

[0126] In this way, the first cooling medium is more accurately distributed between the hot water module 2 and the cooling tower heat dissipation module 3, and the first cooling medium is not easy to flow back into the hot water module 2 and the cooling tower heat dissipation module 3 through the outlet ends of the hot water module 2 and the cooling tower heat dissipation module 3. In addition, by controlling the first flow regulating device and the second flow regulating device, at least one of the hot water module 2 and the cooling tower heat dissipation module 3 can be isolated, which is convenient for overhauling at least one of the hot water module 2 and the cooling tower heat dissipation module 3. In addition, the second flow regulating device can also distribute the first cooling medium flowing through the cooling tower heat dissipation module 3 and the hot water module 2 when the first flow regulating device fails.

[0127] It is understandable that the second flow regulating device can connect the outlet end of the hot water module 2 with the inlet end of the liquid cooling server 1 , and connect the outlet end of the cooling tower heat dissipation module 3 with the inlet end of the liquid cooling server 1 .

[0128] Alternatively, the second flow regulating device can connect the outlet end of the hot water module 2 with the inlet end of the liquid cooling server 1 and disconnect the outlet end of the cooling tower heat dissipation module 3 from the inlet end of the liquid cooling server 1 .

[0129] Alternatively, the second flow regulating device can disconnect the outlet end of the hot water module 2 from the inlet end of the liquid cooling server 1 and connect the outlet end of the cooling tower heat dissipation module 3 to the inlet end of the liquid cooling server 1 .

[0130] In some examples, the second flow regulating device can also disconnect the outlet end of the hot water module 2 from the inlet end of the liquid cooling server 1 , and disconnect the outlet end of the cooling tower heat dissipation module 3 from the inlet end of the liquid cooling server 1 .

[0131] In one feasible manner, the second flow regulating device includes a third two-way valve, the outlet end of the cooling tower heat dissipation module 3 is connected to the inlet end of the liquid cooling server 1 through the third two-way valve, and the hot water module 2 is connected in parallel with the whole formed by the cooling tower heat dissipation module 3 and the third two-way valve, that is, the outlet end of the third two-way valve is connected between the outlet end of the hot water module 2 and the inlet end of the liquid cooling server 1, and the third two-way valve is used to regulate the flow of the first cooling medium flowing through the cooling tower heat dissipation module 3 so as to regulate the flow of the first cooling medium flowing through the hot water module 2.

[0132] In one feasible manner, the second flow regulating device includes a fourth two-way valve, the outlet end of the hot water module 2 is connected to the inlet end of the liquid cooling server 1 through the fourth two-way valve, and the cooling tower heat dissipation module 3 is connected in parallel with the whole formed by the hot water module 2 and the fourth two-way valve, that is, the outlet end of the fourth two-way valve is connected between the outlet end of the cooling tower heat dissipation module 3 and the inlet end of the liquid cooling server 1, and the fourth two-way valve is used to regulate the flow of the first cooling medium flowing through the hot water module 2 so as to regulate the flow of the first cooling medium flowing through the cooling tower heat dissipation module 3.

[0133] In one feasible manner, the second flow regulating device includes a second three-way valve 5, and the outlet ends of the cooling tower heat dissipation module 3 and the hot water module 2 are connected to the inlet end of the liquid cooling server 1 through the second three-way valve 5. The second three-way valve 5 is used to regulate the flow of the first cooling medium flowing through the cooling tower heat dissipation module 3 and the hot water module 2.

[0134] In this way, the connection between the outlet end of the hot water module 2 and the cooling tower heat dissipation module 3 and the inlet end of the liquid cooling server 1 is more convenient. In addition, it is convenient to adjust the flow of the first cooling medium flowing through the hot water module 2 and the cooling tower heat dissipation module 3 by adjusting the opening of the two ports connected to the inlet ends of the hot water module 2 and the cooling tower heat dissipation module 3 of the second three-way valve 5, and the flow regulation is more accurate. In addition, by controlling the first three-way valve 4 and the second three-way valve 5, the hot water module 2 and the cooling tower heat dissipation module 3 can be isolated, which is convenient for the maintenance of the hot water module 2 and the cooling tower heat dissipation module 3. When the hot water module 2 is isolated, the heat can be dissipated through the cooling tower heat dissipation module 3 without affecting the operation of the liquid cooling server 1. When the cooling tower heat dissipation module 3 is isolated, the heat can be dissipated through the hot water module 2 without affecting the operation of the liquid cooling server 1.

[0135] In some examples, the second three-way valve 5 can independently adjust the flow of the first cooling medium flowing through the hot water module 2 and the cooling tower heat dissipation module 3, that is, the second three-way valve 5 can independently adjust the opening of the two ports connected to the outlet ends of the hot water module 2 and the cooling tower heat dissipation module 3. In this way, the two ports of the second three-way valve 5 connected to the outlet ends of the hot water module 2 and the cooling tower heat dissipation module 3 can be closed, and the outlet ends of the hot water module 2 and the cooling tower heat dissipation module 3 are disconnected from the inlet end of the liquid cooling server 1.

[0136] It can be understood that when the inlet end of the hot water module 2 is disconnected from the outlet end of the liquid cooling server 1, the outlet end of the hot water module 2 is disconnected from the inlet end of the liquid cooling server 1, the inlet end of the cooling tower heat dissipation module 3 is connected to the outlet end of the liquid cooling server 1, and the outlet end of the cooling tower heat dissipation module 3 is connected to the inlet end of the liquid cooling server 1, the hot water module 2 can be isolated, and at this time, heat can be dissipated through the cooling tower heat dissipation module 3.

[0137] It can be understood that when the inlet end of the cooling tower heat dissipation module 3 is disconnected from the outlet end of the liquid cooling server 1, the outlet end of the cooling tower heat dissipation module 3 is disconnected from the inlet end of the liquid cooling server 1, the inlet end of the hot water module 2 is connected to the outlet end of the liquid cooling server 1, and the outlet end of the hot water module 2 is connected to the inlet end of the liquid cooling server 1, the cooling tower heat dissipation module 3 can be isolated, and at this time, heat can be dissipated through the hot water module 2.

[0138] It can be understood that when the inlet ends of the hot water module 2 and the cooling tower heat dissipation module 3 are disconnected from the outlet end of the liquid cooling server 1, and the outlet ends of the hot water module 2 and the cooling tower heat dissipation module 3 are disconnected from the inlet end of the liquid cooling server 1, the liquid cooling server 1, the hot water module 2 and the cooling tower heat dissipation module 3 can be isolated from each other. When both the hot water module 2 and the cooling tower heat dissipation module 3 fail, it is convenient to repair the hot water module 2 and the cooling tower heat dissipation module 3 at the same time.

[0139] like Figure 1-Figure 3 As shown, in a possible embodiment, the hot water module 2 includes a first heat exchanger 20 and a water storage tank 24. The first heat exchanger 20 is arranged in parallel with the cooling tower heat dissipation module 3, and the outlet end of the liquid cooling server 1 is connected to the inlet end of the first heat exchanger 20, and the inlet end of the liquid cooling server 1 is connected to the outlet end of the first heat exchanger 20. Among them, the inlet end of at least one of the cooling tower heat dissipation module 3 and the first heat exchanger 20 is connected to the outlet end of the liquid cooling server 1 through a first flow regulating device, and the first flow regulating device is used to regulate the flow of the first cooling medium flowing through the cooling tower heat dissipation module 3 and the first heat exchanger 20. The first cooling medium in the first heat exchanger 20 is used to perform heat exchange with the water in the water storage tank 24.

[0140] Exemplarily, the first heat exchanger 20 may be a plate heat exchanger.

[0141] When the server cooling system is in the first hot water making state, the outlet end of the liquid cooling server 1 is connected to the inlet end of the first heat exchanger 20, and the first cooling medium at least partially flows through the first heat exchanger 20. When the server cooling system is in the first hot water making condition, the first cooling medium partially flows through the first heat exchanger 20 and partially flows through the cooling tower heat dissipation module 3; when the server cooling system is in the second hot water making condition, the first cooling medium flows through the first heat exchanger 20.

[0142] In one practicable manner, the first heat exchanger 20 may be disposed on the surface of the water tank 24 , and the first cooling medium in the first heat exchanger 20 may perform heat exchange with the water in the water tank 24 through the wall of the water tank 24 .

[0143] In a possible embodiment, the first heat exchanger 20 and the water storage tank 24 can be arranged at intervals. The hot water module 2 can also include a second heat exchanger 21. The first heat exchanger 20 includes a first flow channel 201 and a second flow channel 202. The first flow channel 201 is arranged in parallel with the cooling tower heat dissipation module 3, and the inlet end of the first flow channel 201 is connected to the outlet end of the liquid cooling server 1, and the outlet end of the first flow channel 201 is connected to the inlet end of the liquid cooling server 1. The outlet end of the second flow channel 202 is connected to the inlet end of the second heat exchanger 21, and the inlet end of the second flow channel 202 is connected to the outlet end of the second heat exchanger 21. Among them, the inlet end of at least one of the cooling tower heat dissipation module 3 and the first flow channel 201 is connected to the outlet end of the liquid cooling server 1 through a first flow regulating device, and the first flow regulating device is used to regulate the flow of the first cooling medium flowing through the cooling tower heat dissipation module 3 and the first flow channel 201. The first cooling medium in the first flow channel 201 is used to perform heat exchange with the second cooling medium in the second flow channel 202, and the second cooling medium in the second heat exchanger 21 is used to perform heat exchange with the water in the water storage tank 24. In other words, the first cooling medium that absorbs the heat generated by the liquid cooling server 1 and flows into the first flow channel 201 can perform heat exchange with the water in the water storage tank 24 through the second cooling medium circulating between the second flow channel 202 and the second heat exchanger 21.

[0144] It is understandable that when the server cooling system is in the first hot water production state, the outlet end of the liquid-cooled server 1 is connected to the inlet end of the first flow channel 201 , and the first cooling medium flows through the first heat exchanger 20 through the first flow channel 201 .

[0145] In this way, it is possible to reduce the amount of the expensive first cooling medium flowing in the circulation loop formed between the liquid cooling server 1, the hot water module 2 and the cooling tower heat dissipation module 3. In addition, the arrangement of the water storage tank 24 can also be made more flexible.

[0146] In one feasible manner, the second heat exchanger 21 may be disposed on the surface of the water tank 24 , and the second cooling medium in the second heat exchanger 21 may perform heat exchange with the water in the water tank 24 through the wall of the water tank 24 .

[0147] In one feasible manner, the second heat exchanger 21 may include a fifth flow channel 211 and a sixth flow channel 212, the inlet end of the fifth flow channel 211 is connected to the outlet end of the second flow channel 202, the outlet end of the fifth flow channel 211 is connected to the inlet end of the second flow channel 202, the inlet end of the sixth flow channel 212 is connected to the outlet end of the water tank 24, the outlet end of the sixth flow channel 212 is connected to the inlet end of the water tank 24, the water in the water tank 24 can circulate between the sixth flow channel 212 and the water tank 24, when the server cooling system is in the first hot water making state, the second cooling medium can circulate between the second flow channel 202 and the fifth flow channel 211, the second cooling medium can flow through the second heat exchanger 21 through the fifth flow channel 211, and the second cooling medium in the fifth flow channel 211 is used to perform heat exchange with the water circulating from the water tank 24 to the sixth flow channel 212.

[0148] Exemplarily, the second heat exchanger 21 may be a plate heat exchanger.

[0149] In an achievable manner, the hot water module 2 may further include a compressor 22 and a throttling component 23. The outlet end of the second flow channel 202 is connected to the inlet end of the compressor 22, and the outlet end of the compressor 22 is connected to the inlet end of the second heat exchanger 21, so that the inlet end of the second heat exchanger 21 is connected to the outlet end of the second flow channel 202 through the compressor 22, and the outlet end of the second heat exchanger 21 is connected to the inlet end of the throttling component 23, and the outlet end of the throttling component 23 is connected to the inlet end of the second flow channel 202, so that the outlet end of the second heat exchanger 21 is connected to the inlet end of the second flow channel 202 through the throttling component 23.

[0150] In this way, the temperature of the second cooling medium flowing to the second heat exchanger 21 can be increased through compression by the compressor 22, which is beneficial to shorten the time for preparing hot water in the water storage tank 24 and increase the temperature of the hot water prepared in the water storage tank 24. The temperature of the second cooling medium flowing to the second flow channel 202 can be reduced through the throttling component 23, which is beneficial to the second cooling medium in the second flow channel 202 absorbing the heat of the first cooling medium in the first flow channel 201.

[0151] Exemplarily, the throttling component 23 may include but is not limited to a throttling valve, a capillary tube, an electronic expansion valve, etc.

[0152] When the server cooling system is in the first hot water making state, that is, when the server cooling system is in the first hot water making condition and the second hot water making condition, a circulation loop for circulating the second cooling medium formed between the second flow channel 202 of the hot water making module 2, the compressor 22, the second heat exchanger 21 and the throttling component 23 operates, and the circulating second cooling medium absorbs heat in the first cooling medium flowing through the first flow channel 201 of the hot water making module 2 to prepare hot water.

[0153] When the second heat exchanger 21 includes the fifth flow channel 211 and the sixth flow channel 212, the inlet end of the fifth flow channel 211 is connected to the outlet end of the compressor 22, so that the inlet end of the fifth flow channel 211 is connected to the outlet end of the second flow channel 202 through the compressor 22, and the outlet end of the fifth flow channel 211 is connected to the inlet end of the throttling component 23, so that the outlet end of the fifth flow channel 211 is connected to the inlet end of the second flow channel 202 through the throttling component 23.

[0154] Figure 4 This is a schematic diagram of a server cooling system proposed in an embodiment of the present disclosure in a second hot water production state.

[0155] like Figure 4 As shown, in an achievable manner, the hot water making module 2 of the server cooling system may further include a second hot water making state. When the server cooling system is in the second hot water making state, the outlet end of the liquid-cooled server 1 is disconnected from the inlet end of the hot water making module 2, and the first cooling medium flows through the cooling tower heat dissipation module 3 of the server cooling system. When the cooling tower heat dissipation module 3 is running, the hot water making module 2 absorbs heat from the outdoor environment to prepare hot water.

[0156] like Figure 1-Figure 4As shown, in an achievable manner, the hot water module 2 further includes a third heat exchanger 25, a first reversing device 26, a second reversing device 27 and a first switch valve 28. The first reversing device 26 includes a first port, a second port and a third port, and the second reversing device 27 includes a fourth port, a fifth port and a sixth port. The first port is connected to the outlet end of the second flow channel 202, and the second port is connected to the inlet end of the compressor 22, so that the outlet end of the second flow channel 202 is connected to the inlet end of the compressor 22 through the first port and the second port. The fourth port is connected to the outlet end of the throttling component 23, and the fifth port is connected to the inlet end of the second flow channel 202, so that the outlet end of the throttling component 23 is connected to the inlet end of the second flow channel 202 through the fourth port and the fifth port. One end of the third heat exchanger 25 is connected to the third port, and the other end of the third heat exchanger 25 is connected to the sixth port. The third heat exchanger 25 is arranged outdoors, and the second cooling medium in the third heat exchanger 25 is used for heat exchange with the outdoor environment. A first switch valve 28 is connected in series between the fifth port and the inlet end of the second flow channel 202, and the fifth port is connected to the inlet end of the second flow channel 202 through the first switch valve 28. The first reversing device 26 is used to connect the first port with the second port, or to connect the second port with the third port. The second reversing device 27 is used to connect the fourth port with the fifth port, or to connect the fourth port with the sixth port.

[0157] In this way, when the user has a need for hot water, the first reversing device 26 and the second reversing device 27 can be used to adjust the source of heat for heating the water in the water tank 24. If the outdoor temperature is higher than the temperature of the first cooling medium at the outlet of the liquid-cooled server 1, the third heat exchanger 25 can absorb the outdoor heat to heat the water in the water tank 24; when the outdoor temperature is lower than the temperature of the first cooling medium at the outlet of the liquid-cooled server 1, the second cooling medium in the second flow channel 202 can absorb the heat of the first cooling medium in the first flow channel 201 to heat the water in the water tank 24, making the working mode of the server cooling system more diverse. When the user has a need for hot water, the second cooling medium flowing out of the throttling component 23 can be operated in a mode that makes it easier for the second cooling medium to obtain heat according to the outdoor temperature and the temperature of the first cooling medium at the outlet of the liquid-cooled server 1, so that the economy of hot water production is better and the efficiency is higher. In addition, the third heat exchanger 25 absorbs outdoor heat to heat the water in the water tank 24, and the hot water module 2 can independently produce hot water, and can also prepare hot water when the liquid cooling server 1 is in a closed state or fails.

[0158] When the server cooling system is in the second hot water making state, a circulation loop for circulating the second cooling medium formed between the third heat exchanger 25 of the hot water making module 2, the compressor 22, the second heat exchanger 21 and the throttling component 23 operates, that is, the second port is connected with the third port, the fourth port is connected with the sixth port, the first switch valve 28 is closed, the compressor 22 is running, and the circulating second cooling medium absorbs heat from the outdoor environment at the third heat exchanger 25 to prepare hot water.

[0159] When the server cooling system is in the first hot water making state, that is, when the server cooling system is in the first hot water making condition and the second hot water making condition, the first port is connected with the second port, the fourth port is connected with the fifth port, the first switch valve 28 is opened, and the compressor 22 is running.

[0160] It can be understood that the outdoor referred to in the present disclosure may be outside the computer room of the data center.

[0161] Exemplarily, the first reversing device 26 and the second reversing device 27 may be three-way valves, and the first switch valve 28 may be a solenoid valve.

[0162] Exemplarily, the third heat exchanger 25 may be a fin-type heat exchanger.

[0163] In a possible implementation, the server cooling system further includes a controller, and the first flow regulating device, the second flow regulating device, the first reversing device 26, the second reversing device 27, the first switch valve 28 and the compressor 22 are all communicatively connected to the controller.

[0164] It is understandable that the communication connection may be a wired communication connection, for example, it may be connected via optical fiber, conductive wire, etc. The communication connection may also be a wireless communication connection, for example, it may be connected via wifi, Bluetooth, etc.

[0165] like Figure 2 , Figure 3 As shown, when the server cooling system is in the hot water making mode and the temperature of the first cooling medium at the outlet end of the liquid-cooled server 1 is greater than the outdoor temperature at the third heat exchanger 25, the controller is used to control the first flow regulating device, the first reversing device 26, the second reversing device 27, the first switch valve 28 and the compressor 22, so that the server cooling system operates in the first hot water making state, that is, the first cooling medium at least partially flows through the first flow channel 201, the second flow channel 202, the compressor 22, the second heat exchanger 21 and the throttling component 23 to form a circulation loop that circulates the second cooling medium.

[0166] like Figure 4As shown, when the server cooling system is in the hot water making mode and the temperature of the first cooling medium at the outlet end of the liquid-cooled server 1 is lower than the outdoor temperature at the third heat exchanger 25, the controller is used to control the first flow regulating device, the first reversing device 26, the second reversing device 27, the first switch valve 28 and the compressor 22, so that the server cooling system operates in the second hot water making state, that is, the first cooling medium flows through the cooling tower heat dissipation module 3, and the circulation loop formed between the third heat exchanger 25, the compressor 22, the second heat exchanger 21 and the throttling component 23 for circulating the second cooling medium operates.

[0167] In this way, when the user has a demand for hot water, if the temperature of the first cooling medium at the outlet end of the liquid-cooled server 1 is greater than the outdoor temperature at the third heat exchanger 25, it is easier for the second cooling medium flowing out of the throttling component 23 to obtain heat from the first cooling medium in the first flow channel 201, and the third heat exchanger 25 can be isolated in the hot water module 2, and hot water is prepared by heating the liquid-cooled server 1; if the temperature of the first cooling medium at the outlet end of the liquid-cooled server 1 is lower than the outdoor temperature at the third heat exchanger 25, it is easier for the second cooling medium flowing out of the throttling component 23 to obtain heat from the outdoor environment at the third heat exchanger 25, and the first heat exchanger 20 can be isolated in the hot water module 2, and hot water is prepared by heating the outdoor environment at the third heat exchanger 25, which has better economy and higher efficiency in hot water production.

[0168] like Figure 1-Figure 4 As shown, in an achievable manner, a first temperature sensor 11 is provided at the outlet of the liquid cooling server 1, and the first temperature sensor 11 is used to obtain the temperature of the first cooling medium at the outlet of the liquid cooling server 1. A second temperature sensor 251 is provided at the third heat exchanger 25, and the second temperature sensor 251 is used to obtain the ambient temperature at the third heat exchanger 25.

[0169] In this way, it is convenient to obtain the temperature of the first cooling medium at the outlet end of the liquid-cooled server 1 and the ambient temperature at the third heat exchanger 25 in real time, which is beneficial to control the server cooling system according to the temperature of the first cooling medium at the outlet end of the liquid-cooled server 1 and the ambient temperature at the third heat exchanger 25.

[0170] In one achievable manner, both the first temperature sensor 11 and the second temperature sensor 251 are communicatively connected to the controller.

[0171] It is understandable that the server cooling system may further include a processor, the processor is communicatively connected to the controller, and the first temperature sensor 11 and the second temperature sensor 251 may both be communicatively connected to the processor, so that the first temperature sensor 11 and the second temperature sensor 251 are communicatively connected to the controller through the processor. The processor may form corresponding control instructions for controlling the first flow regulating device, the second flow regulating device, the first reversing device 26, the second reversing device 27, the first switch valve 28 and the compressor 22 according to the temperatures obtained by the first temperature sensor 11 and the second temperature sensor 251, and the controller may control the first flow regulating device, the second flow regulating device, the first reversing device 26, the second reversing device 27, the first switch valve 28 and the compressor 22 according to the corresponding control instructions.

[0172] like Figure 2 , Figure 3 As shown, in an embodiment in which the first temperature sensor 11 and the second temperature sensor 251 are communicatively connected to the controller, when the server cooling system is in a hot water making mode and the temperature acquired by the first temperature sensor 11 is greater than the temperature acquired by the second temperature sensor 251, the controller is used to control the first flow regulating device, the first reversing device 26, the second reversing device 27, the first switch valve 28 and the compressor 22, so that the server cooling system operates in a first hot water making state, that is, the first cooling medium at least partially flows through the first flow channel 201, the second flow channel 202, the compressor 22, the second heat exchanger 21 and the throttling component 23 to form a circulation loop that circulates the second cooling medium.

[0173] like Figure 4 As shown, when the server cooling system is in the hot water making mode and the temperature obtained by the first temperature sensor 11 is lower than the temperature obtained by the second temperature sensor 251, the controller is used to control the first flow regulating device, the first reversing device 26, the second reversing device 27, the first switch valve 28 and the compressor 22, so that the server cooling system operates in the second hot water making state, that is, the first cooling medium flows through the cooling tower heat dissipation module 3, and the circulation loop formed between the third heat exchanger 25, the compressor 22, the second heat exchanger 21 and the throttling component 23 for circulating the second cooling medium operates.

[0174] In this way, when the user has a demand for hot water, the server cooling system can be controlled according to the temperature obtained in real time by the first temperature sensor 11 and the second temperature sensor 251 to adjust the source of heat used for hot water, so that the hot water is more economical and efficient.

[0175] In a possible implementation, when the server cooling system is in hot water production mode and the temperature of the first cooling medium at the outlet of the liquid-cooled server 1 is greater than the outdoor temperature at the third heat exchanger 25:

[0176] like Figure 2 As shown, if the flow rate of the first cooling medium at the outlet end of the liquid-cooled server 1 is greater than the first preset flow rate, the controller is also used to control the cooling tower heat dissipation module 3 so that the server cooling system operates in the first hot water making condition, that is, the first cooling medium partially flows through the first flow channel 201 and partially flows through the cooling tower heat dissipation module 3, and the cooling tower heat dissipation module 3 operates.

[0177] like Figure 3 As shown, if the flow rate of the first cooling medium at the outlet end of the liquid-cooled server 1 is less than or equal to the first preset flow rate, the server cooling system operates in the second hot water production condition, that is, the first cooling medium flows through the first flow channel 201.

[0178] In this way, when the flow rate of the first cooling medium at the outlet of the liquid-cooled server 1 is greater than the first preset flow rate, the liquid-cooled server 1 is at a higher load, and the heat generated by the liquid-cooled server 1 is dispersed to the water tank 24 and the cooling tower heat dissipation module 3 for heat dissipation, and it is not easy to cause insufficient heat dissipation capacity of the server cooling system due to heat dissipation through the water tank 24 alone. When the flow rate of the first cooling medium at the outlet of the liquid-cooled server 1 is less than or equal to the first preset flow rate, the liquid-cooled server 1 is at a lower load, and all the heat generated by the liquid-cooled server 1 is supplied to the water tank 24, so that there is enough heat to heat the water in the water tank 24.

[0179] It can be understood that if the server cooling system includes a second regulating device, the second regulating device can be communicatively connected to the controller, and when the server cooling system operates in the first hot water making condition, the second hot water making condition and the second hot water making state, the controller is also used to control the second regulating device.

[0180] It can be understood that the controller can distribute the flow of the first cooling medium flowing through the first flow channel 201 and the cooling tower heat dissipation module 3 according to the temperature of the first cooling medium at the outlet end of the liquid cooling server 1, the outdoor temperature at the third heat exchanger 25, and the flow rate of the first cooling medium at the outlet end of the liquid cooling server 1.

[0181] In some examples, the flow rate of the first cooling medium at the outlet end of the liquid-cooled server 1 may be obtained by a flow meter disposed at the outlet end of the liquid-cooled server 1 , and the flow meter may be communicatively connected to the controller via a processor.

[0182] In one achievable manner, a first driving pump 6 is provided at the outlet end or the inlet end of the liquid cooling server 1 , and the first driving pump 6 is used to drive the first cooling medium to flow out from the outlet end of the liquid cooling server 1 .

[0183] In this way, the first driving pump 6 can not only drive the first cooling medium to circulate, but also obtain the flow rate of the first cooling medium at the outlet end of the liquid cooling server 1 through the rotation speed of the first driving pump 6 .

[0184] It is understandable that the first drive pump 6 can be connected to the processor in communication, so that the first drive pump 6 is connected to the controller in communication through the processor. The processor can form corresponding control instructions for controlling the first flow regulating device and the second flow regulating device according to the temperature obtained by the first temperature sensor 11 and the second temperature sensor 251 and the rotation speed of the first drive pump 6, and the controller can control the first flow regulating device and the second flow regulating device according to the corresponding control instructions.

[0185] In the embodiment in which the first driving pump 6 is provided, the first driving pump 6 and the cooling tower heat dissipation module 3 are both communicatively connected to the controller.

[0186] When the server cooling system is in the hot water mode and the temperature acquired by the first temperature sensor 11 is greater than the temperature acquired by the second temperature sensor 251:

[0187] If the rotation speed of the first driving pump 6 is greater than the first preset rotation speed, the controller is also used to control the cooling tower heat dissipation module 3. The controller is also used to control the cooling tower heat dissipation module 3 so that the server cooling system operates in the first hot water making condition, that is, the first cooling medium partially flows through the first flow channel 201 and partially flows through the cooling tower heat dissipation module 3, and the cooling tower heat dissipation module 3 operates.

[0188] If the rotation speed of the first driving pump 6 is less than or equal to the first preset rotation speed, the server cooling system operates in the second hot water production mode, that is, the first cooling medium flows through the first flow channel 201 .

[0189] The first preset rotation speed is determined by the first preset flow rate.

[0190] In this way, when the server cooling system is in the first hot water making state, the flow rate of the first cooling medium flowing through the first flow channel 201 and the cooling tower 32 heat dissipation system can be distributed according to the real-time rotation speed of the first drive pump 6, so that when the liquid-cooled server 1 is under a higher load, the server cooling system has sufficient heat dissipation capacity; when the liquid-cooled server 1 is under a lower load, the first cooling medium can provide sufficient heat for the water in the water tank 24.

[0191] Figure 5This is a schematic diagram of a server cooling system in a first heat dissipation state proposed by an embodiment of the present disclosure. Figure 6 This is a schematic diagram of a server cooling system proposed in an embodiment of the present disclosure in a second heat dissipation state.

[0192] like Figure 5 , Figure 6 As shown, the server cooling system of the present disclosure has a non-hot water mode, and the non-hot water mode includes a first heat dissipation state and a second heat dissipation state. When the server cooling system is in the first heat dissipation state, the outlet end of the liquid-cooled server 1 is connected to the inlet end of the hot water module 2, the outlet end of the liquid-cooled server 1 is disconnected from the cooling tower heat dissipation module 3, the first cooling medium flows through the hot water module 2, and the first cooling medium is dissipated outdoors through the hot water module 2. When the server cooling system is in the second heat dissipation state, the outlet end of the liquid-cooled server 1 is disconnected from the inlet end of the hot water module 2, the outlet end of the liquid-cooled server 1 is connected to the cooling tower heat dissipation module 3, the first cooling medium flows through the cooling tower heat dissipation module 3, and the first cooling medium is dissipated through the cooling tower heat dissipation module 3.

[0193] like Figure 1-Figure 6 As shown, in an achievable manner, the hot water module 2 further includes a bypass pipeline 29, and the bypass pipeline 29 is connected in parallel with the first switch valve 28. The bypass pipeline 29 includes a gas-liquid separator 292, a liquid pump 293 and a second switch valve 291, and the second switch valve 291, the gas-liquid separator 292 and the liquid pump 293 are connected in series in sequence, and the inlet end of the gas-liquid separator 292 is connected to the fifth port through the second switch valve 291, and the outlet end of the liquid pump 293 is connected to the inlet end of the second flow channel 202. The first reversing device 26 is used to connect the first port with the second port, or the second port with the third port, or the first port with the third port. The second reversing device 27 is used to connect the fourth port with the fifth port, or the fourth port with the sixth port, or the fifth port with the sixth port.

[0194] In this way, when the user has no demand for hot water and the outdoor temperature is low, the first reversing device 26 and the second reversing device 27 can be used for reversal, so that a circulation loop is formed between the third heat exchanger 25 and the second flow channel 202, so that after the second cooling medium in the second flow channel 202 absorbs the heat of the first cooling medium in the first flow channel 201, the heat can be dissipated through the third heat exchanger 25. At this time, the first cooling medium that has absorbed the heat of the liquid-cooled server 1 can flow into the first flow channel 201 for heat exchange, which can reduce the energy consumption of the cooling tower heat dissipation module 3 and make the energy consumption of the server cooling system lower.

[0195] It can be understood that the liquid pump 293 can be used to drive the second cooling medium to circulate in the circulation loop formed by the second flow channel 202 and the third heat exchanger 25 .

[0196] It is understandable that the gas-liquid separator 292 can separate the gas phase and liquid phase of the second cooling medium, and allow the liquid phase of the second cooling medium to flow to the liquid pump 293, thereby reducing the risk of the gas phase of the second cooling medium entering the liquid pump 293 and causing a malfunction.

[0197] It can be understood that the inlet end of the gas-liquid separator 292 is located at the upper part of the gas-liquid separator 292, and the outlet end of the gas-liquid separator 292 is located at the lower part of the gas-liquid separator 292. The liquid phase of the second cooling medium in the gas-liquid separator 292 flows out from the outlet end of the gas-liquid separator 292 under the action of its own gravity, and the gas phase of the second cooling medium in the gas-liquid separator 292 is retained in the upper part of the gas-liquid separator 292. The gas phase of the second cooling medium retained in the upper part of the gas-liquid separator 292 can be cooled by the supercooled second cooling medium flowing in from the inlet end of the gas-liquid separator 292 and become a liquid phase.

[0198] It can be understood that the liquid pump 293 and the second switch valve 291 can be communicatively connected to the controller. When the server cooling system operates in the first hot water making condition, the second hot water making condition and the second hot water making state, the controller is also used to control the liquid pump 293 and the second switch valve 291.

[0199] It can be understood that when the server cooling system is in the first hot water making condition, the second hot water making condition and the second hot water making state, the second switch valve 291 is closed.

[0200] Exemplarily, the second switch valve 291 may be a solenoid valve.

[0201] In one feasible manner, the bypass line 29 also includes a third switch valve 294, the second switch valve 291, the gas-liquid separator 292, the liquid pump 293 and the third switch valve 294 are connected in series in sequence, and the outlet end of the liquid pump 293 is connected to the inlet end of the second flow channel 202 through the third switch valve 294.

[0202] In this way, when the second switch valve 291 is closed, the closed third switch valve 294 makes it difficult for the second cooling medium to flow back through the outlet of the liquid cooling and enter the liquid pump 293 and other devices. In addition, the third switch valve 294 can disconnect the bypass pipeline 29 when the second switch valve 291 fails. In addition, the gas-liquid separator 292 and the liquid pump 293 can be isolated by the second switch valve 291 and the third switch valve 294, which is convenient for the maintenance of the gas-liquid separator 292 and the liquid pump 293.

[0203] It can be understood that the third switch valve 294 can be communicatively connected to the controller, and when the server cooling system operates in the first hot water making condition, the second hot water making condition and the second hot water making state, the controller is also used to control the third switch valve 294.

[0204] It can be understood that when the server cooling system is in the first hot water making condition, the second hot water making condition and the second hot water making state, the third switch valve 294 is closed.

[0205] Exemplarily, the third switch valve 294 may be a solenoid valve.

[0206] In an achievable manner, the cooling tower heat dissipation module 3 includes a fourth heat exchanger 31 and a cooling tower 32. The fourth heat exchanger 31 includes a third flow channel 311 and a fourth flow channel 312. The third flow channel 311 is arranged in parallel with the first flow channel 201, and the inlet end of the third flow channel 311 is connected to the outlet end of the liquid cooling server 1, and the outlet end of the third flow channel 311 is connected to the inlet end of the liquid cooling server 1. The inlet end of the fourth flow channel 312 is connected to the outlet end of the cooling tower 32, and the outlet end of the fourth flow channel 312 is connected to the inlet end of the cooling tower 32. Among them, the inlet end of at least one of the third flow channel 311 and the first flow channel 201 is connected to the outlet end of the liquid cooling server 1 through a first flow regulating device, and the first flow regulating device is used to regulate the flow of the first cooling medium flowing through the third flow channel 311 and the first flow channel 201. The first cooling medium in the third flow channel 311 is used to perform heat exchange with the third cooling medium in the fourth flow channel 312.

[0207] It can be understood that the outlet end of at least one of the third flow channel 311 and the first flow channel 201 is connected to the outlet end of the liquid cooling server 1 through the second flow regulating device.

[0208] like Figure 5 As shown, when the server cooling system is in a non-hot water mode, the temperature of the third cooling medium at the inlet end of the fourth flow channel 312 is greater than the outdoor temperature at the third heat exchanger 25, and the flow rate of the first cooling medium at the outlet end of the liquid-cooled server 1 is less than or equal to the second preset flow rate, the controller is used to control the first flow regulating device, the first reversing device 26, the second reversing device 27, the first switch valve 28, the compressor 22, the second switch valve 291 and the liquid pump 293, so that the server cooling system operates in a first heat dissipation state. When the server cooling system is in the first heat dissipation state, the inlet end of the first flow channel 201 is connected to the outlet end of the liquid-cooled server 1, and the inlet end of the third flow channel 311 is disconnected from the outlet end of the liquid-cooled server 1. The first cooling medium flows through the first flow channel 201, and the circulation loop formed by the first heat exchanger 20, the third heat exchanger 25, the gas-liquid separator 292 and the liquid pump 293 for circulating the second cooling medium operates. The compressor 22 stops running, and the second cooling medium absorbs the heat of the first cooling medium in the first flow channel 201 in the second flow channel 202, and then flows to the third heat exchanger 25 for outdoor heat dissipation.

[0209] In this way, when the user has no demand for hot water, the outdoor temperature is low, and the liquid-cooled server 1 is under a low load, the heat generated by the liquid-cooled server 1 can be dissipated outdoors through the third heat exchanger 25, and the cooling tower heat dissipation module 3 does not need to operate, so that the energy consumption of the server cooling system is lower.

[0210] It can be understood that when the server cooling system is in the first heat dissipation state, the first port is connected to the third port, the fifth port is connected to the sixth port, the first switch valve 28 is closed, the second switch valve 291 and the third switch valve 294 are opened, and the liquid pump 293 is running.

[0211] like Figure 6 As shown, when the server cooling system is in a non-hot water mode, if the temperature of the third cooling medium at the inlet end of the fourth flow channel 312 is less than or equal to the outdoor temperature at the third heat exchanger 25, or the flow rate of the first cooling medium at the outlet end of the liquid-cooled server 1 is greater than the second preset flow rate, the controller is used to control the first flow regulating device, the first reversing device 26, the second reversing device 27, the first switch valve 28, the compressor 22, the second switch valve 291 and the liquid pump 293, so that the server cooling system operates in a second heat dissipation state. When the server cooling system is in the second heat dissipation state, the inlet end of the first flow channel 201 is disconnected from the outlet end of the liquid-cooled server 1, and the inlet end of the third flow channel 311 is connected to the outlet end of the liquid-cooled server 1. The first cooling medium flows through the third flow channel 311, and a circulation loop for circulating the third cooling medium formed between the fourth flow channel 312 and the cooling tower 32 is in operation. The hot water module 2 stops running, and the first cooling medium dissipates heat at the cooling tower 32 through the circulating third cooling medium. That is, the third cooling medium absorbs the heat of the first cooling medium in the third flow channel 311 in the fourth flow channel 312 and then flows to the cooling tower 32 for heat dissipation.

[0212] In this way, when the outdoor temperature is high or the liquid-cooled server 1 is under a high load, if the user has no demand for hot water, the heat generated by the liquid-cooled server 1 can be dissipated through the cooling tower 32, and the heat dissipation of the liquid-cooled server 1 is relatively stable.

[0213] It is understandable that if the server cooling system includes a second regulating device and a third switch valve 294 , when the server cooling system operates in the first heat dissipation state and the second heat dissipation state, the controller is also used to control the second regulating device and the third switch valve 294 .

[0214] It is understandable that when the server cooling system is in the second heat dissipation state, the liquid pump 293 and the compressor 22 both stop running.

[0215] like Figure 1-Figure 6As shown, in a possible embodiment, a third temperature sensor 33 is provided at the inlet end of the fourth flow channel 312, and the third temperature sensor 33 is used to obtain the temperature of the third cooling medium at the inlet end of the fourth flow channel 312, and the third temperature sensor 33 and the cooling tower 32 are both communicatively connected to the controller of the server cooling system.

[0216] In this way, it is convenient to obtain the temperature of the third cooling medium at the inlet end of the fourth flow channel 312 in real time, and it is beneficial to control the server cooling system according to the temperature of the third cooling medium at the inlet end of the fourth flow channel 312.

[0217] It is understandable that the third temperature sensor 33 can be connected to the processor in communication, so that the third temperature sensor 33 is connected to the controller in communication through the processor. The processor can form corresponding control instructions for controlling the first flow regulating device, the second flow regulating device, the first reversing device 26, the second reversing device 27, the first switch valve 28, the second switch valve 291, the third switch valve 294, the liquid pump 293, the compressor 22 and the cooling tower 32 according to the temperatures obtained by the second temperature sensor 251 and the third temperature sensor 33, and the controller can control the first flow regulating device, the second flow regulating device, the first reversing device 26, the second reversing device 27, the first switch valve 28, the second switch valve 291, the third switch valve 294, the liquid pump 293, the compressor 22 and the cooling tower 32 according to the corresponding control instructions.

[0218] like Figure 5 As shown, in the embodiment where the third temperature sensor 33 is communicatively connected to the controller, when the server cooling system is in a non-hot water mode, the temperature obtained by the third temperature sensor 33 is greater than the temperature obtained by the second temperature sensor 251 of the server cooling system, and the speed of the first driving pump 6 is less than or equal to the second preset speed, the controller is used to control the first flow regulating device, the first reversing device 26, the second reversing device 27, the first switch valve 28, the compressor 22, the second switch valve 291 and the liquid pump 293, so that the server cooling system operates in the first heat dissipation state. The second preset speed is determined by the second preset flow.

[0219] In this way, when the user has no demand for hot water, the heat dissipation method can be controlled according to the temperature obtained by the second temperature sensor 251 and the third temperature sensor 33 and the speed of the first drive pump 6, so that when the outdoor temperature is low and the liquid-cooled server 1 is under a low load, the server cooling system can be controlled to perform outdoor heat dissipation through the third heat exchanger 25.

[0220] like Figure 6As shown, when the server cooling system is in a non-hot water mode, if the temperature obtained by the third temperature sensor 33 is less than or equal to the temperature obtained by the second temperature sensor 251, or the speed of the first drive pump 6 is greater than the second preset speed, the controller is used to control the first flow regulating device, the first reversing device 26, the second reversing device 27, the first switch valve 28, the compressor 22, the second switch valve 291, the liquid pump 293 and the cooling tower 32, so that the server cooling system operates in a second heat dissipation state.

[0221] In this way, when the user has no demand for hot water, the heat dissipation method can be controlled according to the temperature obtained by the second temperature sensor 251 and the third temperature sensor 33 and the speed of the first drive pump 6, so that when the outdoor temperature is high or the liquid-cooled server 1 is under a high load, the server cooling system can be controlled to dissipate heat through the cooling tower 32.

[0222] like Figure 1-Figure 6 As shown, in a possible embodiment, a second driving pump 34 is connected in series between the outlet end of the cooling tower 32 and the inlet end of the fourth flow channel 312, and the second driving pump 34 is used to drive the third cooling medium at the outlet end of the cooling tower 32 to flow to the inlet end of the fourth flow channel 312.

[0223] In this way, it is convenient to drive the third cooling medium to circulate between the cooling tower 32 and the fourth flow channel 312 .

[0224] When the circulation loop formed by the first heat exchanger 20, the third heat exchanger 25, the gas-liquid separator 292 and the liquid pump 293 for circulating the second cooling medium is running, that is, when the server cooling system is in the first heat dissipation state, if the pressure at the outlet end of the gas-liquid separator 292 is greater than the first preset pressure, and the temperature at the outlet end of the gas-liquid separator 292 is greater than the first preset temperature, the controller is used to control the liquid pump 293, the first flow regulating device and the cooling tower heat dissipation module 3, so that the server cooling system switches to the second heat dissipation state, that is, the first cooling medium flows through the cooling tower heat dissipation module 3, the cooling tower heat dissipation module 3 is running, and the liquid pump 293 stops running.

[0225] In this way, based on the temperature and pressure at the outlet end of the gas-liquid separator 292, it can be determined whether a large amount of the second gas-phase cooling medium flows out of the outlet end of the gas-liquid separator 292. When a large amount of the second gas-phase cooling medium flows out of the outlet end of the gas-liquid separator 292, the liquid pump 293 can be closed and switched to the second heat dissipation state. This can reduce the risk of malfunction caused by excessive amount of the second gas-phase cooling medium entering the liquid pump 293, and enable the server cooling system to dissipate heat normally through the cooling tower heat dissipation module 3, so that the liquid-cooled server 1 can operate normally.

[0226] In one practicable manner, a detection device 295 is provided at the outlet of the gas-liquid separator 292 , and the detection device 295 is used to obtain the pressure and temperature of the outlet of the gas-liquid separator 292 .

[0227] In this way, it is convenient to obtain the pressure and temperature of the outlet end of the gas-liquid separator 292 in real time, and it is convenient to control the server cooling system according to the pressure and temperature of the outlet end of the gas-liquid separator 292.

[0228] In one practicable manner, the detection device 295 is communicatively connected to a controller of the server cooling system.

[0229] When the circulation loop formed by the first heat exchanger 20, the third heat exchanger 25, the gas-liquid separator 292 and the liquid pump 293 for circulating the second cooling medium is running, that is, when the server cooling system is in the first heat dissipation state, if the pressure obtained by the detection device 295 is greater than the first preset pressure, and the temperature obtained by the detection device 295 is greater than the first preset temperature, the controller is used to control the liquid pump 293, the first flow regulating device and the cooling tower heat dissipation module 3, so that the first cooling medium flows through the cooling tower heat dissipation module 3, the cooling tower heat dissipation module 3 is running, and the liquid pump 293 stops running.

[0230] In this way, when the server cooling system is in the first heat dissipation state, the heat dissipation method can be controlled according to the temperature and pressure obtained by the detection device 295 to reduce the risk of excessive gas phase second cooling medium entering the liquid pump 293 and causing failure.

[0231] In one practicable manner, a fan 252 is provided at the third heat exchanger 25 , and the fan 252 is used to accelerate the flow of air at the third heat exchanger 25 .

[0232] In this way, the fan 252 can improve the heat dissipation efficiency of the second cooling medium in the third heat exchanger 25, so that the temperature of the second cooling medium flowing out from the outlet end of the third heat exchanger 25 is lower, and the gas phase second cooling medium flowing out from the outlet end of the gas-liquid separator 292 is less.

[0233] In one practicable manner, the controller is used to control the rotation speed of the fan 252 according to the pressure and temperature at the outlet of the gas-liquid separator 292 .

[0234] In this way, when the gas phase second cooling medium flows out from the outlet of the gas-liquid separator 292, the heat exchange performance of the third heat exchanger 25 can be improved by adjusting the rotation speed of the fan 252 to reduce the temperature of the second cooling medium entering the gas-liquid separator 292, thereby increasing the supercooling of the second cooling medium flowing out through the outlet of the gas-liquid separator 292, so as to reduce the amount of the gas phase second cooling medium flowing out from the outlet of the gas-liquid separator 292, so as to reduce the risk of excessive gas phase second cooling medium entering the liquid pump 293 and causing failure. In addition, the rotation speed of the fan 252 can be adjusted according to the temperature and pressure of the outlet of the gas-liquid separator 292. When the temperature and pressure of the outlet of the gas-liquid separator 292 meet the requirements, the fan 252 can be operated at a lower rotation speed, which is conducive to reducing energy consumption.

[0235] In an embodiment in which the detection device 295 is provided, the fan 252 is in communication connection with a controller of the server cooling system, and the controller is used to control the rotation speed of the fan 252 according to the pressure and temperature obtained by the detection device 295 .

[0236] In this way, the rotation speed of the fan 252 can be adjusted in real time by detecting the pressure and temperature obtained by the detection device 295, and the rotation speed of the fan 252 can be controlled more accurately.

[0237] It can be understood that the detection device 295 can be communicatively connected to the processor, so that the detection device 295 is communicatively connected to the controller through the processor. The processor can form corresponding control instructions for controlling the liquid pump 293, the fan 252, the server output flow control device, the second flow control device and the cooling tower 32 according to the pressure and temperature obtained by the detection device 295. The controller can control the liquid pump 293, the fan 252, the server output flow control device, the second flow control device and the cooling tower 32 according to the corresponding control instructions.

[0238] When the server cooling system is in the first heat dissipation state and the rotation speed of the fan 252 of the server cooling system is less than the maximum rotation speed, if the temperature at the outlet of the gas-liquid separator 292 is greater than the second preset temperature and less than the first preset temperature, or the pressure at the outlet of the gas-liquid separator 292 is greater than the second preset pressure and less than the first preset pressure, the server cooling system is controlled to increase the rotation speed of the fan 252. The first preset temperature is greater than the second preset temperature, and the first preset pressure is greater than the second preset pressure.

[0239] In this way, before switching the first cooling state to the second cooling state, the pressure and temperature at the outlet of the gas-liquid separator 292 can be reduced by increasing the rotation speed of the fan 252, so as to extend the time that the server cooling system is in the first cooling state, which is conducive to reducing energy consumption.

[0240] In an embodiment in which a detection device 295 is provided, when the server cooling system is in a first heat dissipation state and the rotation speed of the fan 252 of the server cooling system is less than the maximum rotation speed, if the temperature obtained by the detection device 295 is greater than the second preset temperature and less than the first preset temperature, or the pressure obtained by the detection device 295 is greater than the second preset pressure and less than the first preset pressure, the server cooling system is controlled to increase the rotation speed of the fan 252.

[0241] In an achievable manner, the compressor 22 is a variable frequency compressor. The controller is used to control the frequency of the compressor 22 according to the water temperature in the water storage tank 24 .

[0242] Like this, can control the water temperature in the water storage tank 24 by changing the frequency of compressor 22. In addition, after the water temperature in the water storage tank 24 meets the requirement, compressor 22 can be operated at a lower frequency, which is conducive to reducing energy consumption.

[0243] In one practicable manner, a fourth temperature sensor 241 is provided at the water tank 24 , and the fourth temperature sensor 241 is used to obtain the water temperature in the water tank 24 .

[0244] In this way, it is convenient to obtain the water temperature in the water tank 24 in real time, which is beneficial to control the server cooling system according to the water temperature in the water tank 24.

[0245] In an embodiment in which a fourth temperature sensor 241 is provided, the fourth temperature sensor 241 is communicatively connected to a controller of the server cooling system, and the controller is used to control the frequency of the compressor 22 according to the water temperature obtained by the fourth temperature sensor 241 .

[0246] In this way, the frequency of the compressor 22 can be adjusted in real time through the temperature obtained by the fourth temperature sensor 241, and the frequency control of the compressor 22 is more accurate.

[0247] It is understandable that the fourth temperature sensor 241 can be connected to the processor in communication, so that the fourth temperature sensor 241 is connected to the controller in communication through the processor. The processor can form a corresponding control instruction for controlling the compressor 22 according to the water temperature obtained by the fourth temperature sensor 241, and the controller can control the compressor 22 according to the corresponding control instruction.

[0248] Figure 7 A schematic diagram of a control method for a server cooling system proposed in an embodiment of the present disclosure.

[0249] like Figure 7 As shown, and see Figure 2-Figure 6 On the other hand, the present disclosure provides a control method for a server cooling system, which is used for the server cooling system in any of the above embodiments.

[0250] The control method comprises the steps of:

[0251] A first temperature is obtained, wherein the first temperature is the temperature of the first cooling medium at the outlet end of the liquid cooling server 1 .

[0252] A second temperature is obtained, where the second temperature is an outdoor temperature.

[0253] When the server cooling system is in a hot water production mode, the first temperature and the second temperature are compared.

[0254] If the first temperature is greater than the second temperature, the server cooling system is controlled to operate in a first hot water making state.

[0255] In this way, when the first temperature is greater than the second temperature and the user has a demand for hot water, the hot water making module 2 can absorb the heat in the first cooling medium to prepare hot water, and the heat generated by the liquid-cooled server 1 can be recovered. When preparing hot water, the liquid-cooled server 1 can dissipate heat, which is beneficial to reducing the energy consumption of dissipating heat for the liquid-cooled server 1.

[0256] It can be understood that the first temperature can be obtained by the first temperature sensor 11 , and the second temperature can be obtained by the second temperature sensor 251 .

[0257] In one feasible manner, when the server cooling system is in the first hot water making state, a circulation loop for circulating the second cooling medium formed between the second flow channel 202 of the hot water making module 2, the compressor 22, the second heat exchanger 21 and the throttling component 23 operates, and the circulating second cooling medium absorbs heat from the first cooling medium flowing through the first flow channel 201 of the hot water making module 2 to prepare hot water.

[0258] In this way, the temperature of the second cooling medium flowing to the second heat exchanger 21 can be increased through compression by the compressor 22, which is beneficial to shorten the time for preparing hot water in the water storage tank 24 and increase the temperature of the hot water prepared in the water storage tank 24. The temperature of the second cooling medium flowing to the second flow channel 202 can be reduced through the throttling component 23, which is beneficial to the second cooling medium in the second flow channel 202 absorbing the heat of the first cooling medium in the first flow channel 201.

[0259] In one achievable manner, the control method further comprises the steps of:

[0260] The server output flow is obtained, wherein the server output flow is the flow of the first cooling medium at the outlet end of the liquid cooling server 1 .

[0261] When the server cooling system is in a hot water production mode, the server output flow rate is compared with a first preset flow rate.

[0262] If the first temperature is greater than the second temperature, controlling the server cooling system to operate in a first hot water production state specifically includes:

[0263] If the first temperature is greater than the second temperature and the server output flow is greater than the first preset flow, the server cooling system is controlled to operate in the first hot water production condition.

[0264] If the first temperature is greater than the second temperature and the server output flow is less than or equal to the first preset flow, the server cooling system is controlled to operate in the second hot water making condition.

[0265] In this way, when the flow rate of the first cooling medium at the outlet of the liquid-cooled server 1 is greater than the first preset flow rate, the liquid-cooled server 1 is at a higher load, and the heat generated by the liquid-cooled server 1 is dispersed to the water tank 24 and the cooling tower heat dissipation module 3 for heat dissipation, and it is not easy to cause insufficient heat dissipation capacity of the server cooling system due to heat dissipation through the water tank 24 alone. When the flow rate of the first cooling medium at the outlet of the liquid-cooled server 1 is less than or equal to the first preset flow rate, the liquid-cooled server 1 is at a lower load, and all the heat generated by the liquid-cooled server 1 is supplied to the water tank 24, so that there is enough heat to heat the water in the water tank 24.

[0266] It can be understood that the server output flow can be obtained through the first drive pump 6.

[0267] In one achievable manner, the hot water production mode further includes a second hot water production state.

[0268] The control method further comprises the steps of:

[0269] When the server cooling system is in a hot water making mode, if the first temperature is lower than the second temperature, the server cooling system is controlled to operate in a second hot water making state.

[0270] In this way, when the user has a demand for hot water, if the first temperature is lower than the second temperature, it is easier for the second cooling medium flowing out of the throttling component 23 to obtain heat from the outdoor environment at the third heat exchanger 25. The first heat exchanger 20 can be isolated in the hot water module 2, and hot water can be prepared by heating the outdoor environment at the third heat exchanger 25. The economy and efficiency of hot water production are better.

[0271] In one feasible manner, when the server cooling system is in the second hot water making state, a circulation loop for circulating the second cooling medium formed between the third heat exchanger 25 of the hot water making module 2, the compressor 22, the second heat exchanger 21 and the throttling component 23 operates, and the circulating second cooling medium absorbs heat from the outdoor environment at the third heat exchanger 25 to prepare hot water.

[0272] In this way, the temperature of the second cooling medium flowing to the second heat exchanger 21 can be increased through compression by the compressor 22, which is beneficial to shorten the time for preparing hot water in the water tank 24 and increase the temperature of the hot water prepared in the water tank 24. The temperature of the second cooling medium flowing to the third heat exchanger 25 can be reduced through the throttling component 23, which is beneficial to the second cooling medium in the third heat exchanger 25 absorbing heat from the outdoor environment.

[0273] In one achievable manner, the control method further comprises the steps of:

[0274] A third temperature is acquired, wherein the third temperature is the temperature of the third cooling medium at the inlet end of the fourth flow channel 312 of the server cooling system.

[0275] When the server cooling system is in a non-hot water production mode, the second temperature is compared with the third temperature, and the second preset flow rate is compared with the acquired server output flow rate.

[0276] If the third temperature is greater than the second temperature and the server output flow is less than or equal to the second preset flow, the server cooling system is controlled to operate in the first heat dissipation state.

[0277] In this way, when the user has no demand for hot water, the outdoor temperature is low, and the liquid-cooled server 1 is under a low load, the heat generated by the liquid-cooled server 1 can be dissipated outdoors through the third heat exchanger 25, and the cooling tower heat dissipation module 3 does not need to operate, so that the energy consumption of the server cooling system is lower.

[0278] It can be understood that the third temperature can be obtained by the third temperature sensor 33 .

[0279] In one feasible manner, when the server cooling system is in the first heat dissipation state, a circulation loop for circulating the second cooling medium formed between the second flow channel 202 of the hot water module 2, the third heat exchanger 25, the gas-liquid separator 292 and the liquid pump 293 operates, and the first cooling medium dissipates heat outdoors at the third heat exchanger 25 through the circulating second cooling medium.

[0280] In this way, when the user does not need to make hot water, it is convenient to achieve heat dissipation through the outdoor environment. In addition, the second cooling medium flows into the liquid pump 293 after passing through the gas-liquid separator 292, which can reduce the risk of excessive gas phase of the second cooling medium entering the liquid pump 293 and causing the liquid pump 293 to fail.

[0281] In one achievable manner, the control method further comprises the steps of:

[0282] The temperature and pressure at the outlet of the gas-liquid separator 292 of the server cooling system are obtained.

[0283] When the server cooling system is in the first heat dissipation state, the temperature of the outlet of the gas-liquid separator 292 is compared with the first preset temperature, and the pressure of the outlet of the gas-liquid separator 292 is compared with the first preset pressure.

[0284] If the temperature at the outlet of the gas-liquid separator 292 is greater than the first preset temperature and the pressure at the outlet of the gas-liquid separator 292 is greater than the first preset pressure, the server cooling system is controlled to switch to the second heat dissipation state.

[0285] In this way, based on the temperature and pressure at the outlet end of the gas-liquid separator 292, it can be determined whether a large amount of the second gas-phase cooling medium flows out of the outlet end of the gas-liquid separator 292. When a large amount of the second gas-phase cooling medium flows out of the outlet end of the gas-liquid separator 292, the liquid pump 293 can be closed and switched to the second heat dissipation state. This can reduce the risk of malfunction caused by excessive amount of the second gas-phase cooling medium entering the liquid pump 293, and enable the server cooling system to dissipate heat normally through the cooling tower heat dissipation module 3, so that the liquid-cooled server 1 can operate normally.

[0286] It can be understood that the temperature and pressure at the outlet of the gas-liquid separator 292 can be obtained by the detection device 295 .

[0287] In an achievable manner, when the server cooling system is in the first heat dissipation state and the rotation speed of the fan 252 of the server cooling system is less than the maximum rotation speed, if the temperature at the outlet of the gas-liquid separator 292 is greater than the second preset temperature and less than the first preset temperature, or if the pressure at the outlet of the gas-liquid separator 292 is greater than the second preset pressure and less than the first preset pressure, the server cooling system is controlled to increase the rotation speed of the fan 252. The first preset temperature is greater than the second preset temperature, and the first preset pressure is greater than the second preset pressure.

[0288] In this way, when the gas phase second cooling medium flows out from the outlet of the gas-liquid separator 292, the heat exchange performance of the third heat exchanger 25 can be improved by adjusting the rotation speed of the fan 252 to reduce the temperature of the second cooling medium entering the gas-liquid separator 292, thereby increasing the supercooling of the second cooling medium flowing out through the outlet of the gas-liquid separator 292, so as to reduce the amount of the gas phase second cooling medium flowing out from the outlet of the gas-liquid separator 292, so as to reduce the risk of excessive gas phase second cooling medium entering the liquid pump 293 and causing failure. In addition, by increasing the rotation speed of the fan 252 to reduce the pressure and temperature at the outlet of the gas-liquid separator 292, the time that the server cooling system is in the first heat dissipation state can be extended, which is conducive to reducing energy consumption.

[0311] The fourth control module is used to control the server cooling system to switch to the second heat dissipation state if the temperature of the outlet end of the gas-liquid separator 292 is greater than the first preset temperature and the pressure of the outlet end of the gas-liquid separator 292 is greater than the first preset pressure.
