Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of data centers, in particular to a cooling system, a control method, a device, equipment, a system, a medium and a product. BACKGROUND

[0002] A data center usually contains two sets of refrigeration systems, a liquid cooling module and an air cooling module. The liquid cooling module is responsible for heat dissipation in the liquid cooling part, and the air cooling module is responsible for heat dissipation in the air cooling part.

[0003] In the related art, the air cooling module and the liquid cooling module cooperate to cool electronic equipment in the cabinet, but the liquid cooling module and the air cooling module cannot achieve the best cooling effect on the electronic equipment. SUMMARY

[0004] According to an aspect of the present disclosure, a cooling system is provided, comprising: a primary side pipeline, a first heat exchanger, a second heat exchanger, a liquid cooling module, an air cooling module, and a controllable switch module, a secondary side passage of the first heat exchanger being in communication with the liquid cooling module, a secondary side passage of the second heat exchanger being in communication with the air cooling module;

[0005] When the cooling system operates in an initial cooling mode, the primary side passage of the first heat exchanger and the primary side passage of the second heat exchanger are arranged on the primary side pipeline in a first connection mode through the controllable switch module, and the primary side passage inlet measured temperature and the primary side passage outlet measured temperature of the first heat exchanger satisfy the relaxation heat exchange constraint condition at the same time;

[0006] When the cooling system operates in a first target cooling mode, the primary side passage of the first heat exchanger and the primary side passage of the second heat exchanger are arranged on the primary side pipeline in a second connection mode through the controllable switch module, and the primary side passage inlet measured temperature and / or the primary side passage outlet measured temperature do not satisfy the relaxation heat exchange constraint condition;

[0007] In the case that the cooling liquid temperature of the primary side pipeline is the same, the heat exchange capacity of the first heat exchanger in the first target cooling mode is higher than that of the first heat exchanger in the initial cooling mode, and the power consumption of the air cooling module in the first target cooling mode is higher than that of the air cooling module in the initial cooling mode.

[0008] According to another aspect of the present disclosure, a control method of a cooling system is provided, the cooling system being the cooling system described in the present application. When the operation mode of the cooling system is an initial cooling mode, the method comprises:

[0009] obtaining a primary side passage inlet measured temperature of the first heat exchanger and a primary side passage outlet measured temperature of the first heat exchanger;

[0010] maintain the operation mode of the cooling system if the primary-side passage inlet measured temperature and the primary-side passage outlet measured temperature both satisfy the relaxed heat exchange constraint condition;

[0011] if the primary-side passage inlet measured temperature and / or the primary-side passage outlet measured temperature do not both satisfy the relaxed heat exchange constraint condition, control the controllable switch module to modify the operation mode of the cooling system from the initial cooling mode to a first target cooling mode based on the primary-side passage inlet measured temperature and the primary-side passage outlet measured temperature;

[0012] in the case of the same coolant temperature of the primary-side pipeline, the heat exchange capacity of the first heat exchanger in the first target cooling mode is higher than the heat exchange capacity of the first heat exchanger in the initial cooling mode, and the power consumption of the air cooling module in the first target cooling mode is higher than the power consumption of the air cooling module in the initial cooling mode.

[0013] According to another aspect of the present disclosure, a control device of a cooling system is provided, the cooling system being the cooling system described in the present application, and when the operation mode of the cooling system is an initial cooling mode, the device comprises:

[0014] an acquisition module configured to acquire a primary-side passage inlet measured temperature of a first heat exchanger and a primary-side passage outlet measured temperature of the first heat exchanger;

[0015] a maintenance module configured to maintain the operation mode of the cooling system if the primary-side passage inlet measured temperature and the primary-side passage outlet measured temperature both satisfy the relaxed heat exchange constraint condition;

[0016] a switching module configured to control the controllable switch module to modify the operation mode of the cooling system from the initial cooling mode to a first target cooling mode based on the primary-side passage inlet measured temperature and the primary-side passage outlet measured temperature if the primary-side passage inlet measured temperature and / or the primary-side passage outlet measured temperature do not both satisfy the relaxed heat exchange constraint condition;

[0017] in the case of the same coolant temperature of the primary-side pipeline, the heat exchange capacity of the first heat exchanger in the first target cooling mode is higher than the heat exchange capacity of the first heat exchanger in the initial cooling mode, and the power consumption of the air cooling module in the first target cooling mode is higher than the power consumption of the air cooling module in the initial cooling mode.

[0018] According to another aspect of the present disclosure, a control system is provided, comprising: a cooling system, an induction module, and a control module, wherein the cooling system comprises the cooling system described in the present application, and the control module is in communication connection with the controllable switch module and the induction module respectively;

[0019] The induction module is configured to send at least the primary side channel inlet measured temperature and the primary side channel outlet measured temperature of the first heat exchanger to the control module.

[0020] The control module is configured to execute the method described in the present application based on the primary side channel inlet measured temperature and the primary side channel outlet measured temperature.

[0021] According to another aspect of the present disclosure, an electronic device is provided, comprising:

[0022] a processor; and

[0023] a memory storing a program;

[0024] The program comprises instructions which, when executed by the processor, cause the processor to execute the method described in the present application.

[0025] According to another aspect of the present disclosure, a non-transitory computer readable storage medium is provided, which stores computer instructions for causing a computer to execute the method described in the present application.

[0026] According to another aspect of the present disclosure, a computer program product is provided, comprising a computer program, wherein the computer program, when executed by a processor, implements the method described in the present application.

[0027] In one or more technical solutions provided in the embodiments of the present application, when the cooling system is running in the initial cooling mode, the primary side channel inlet measured temperature and the primary side channel outlet measured temperature simultaneously satisfy the relaxation heat exchange constraint condition, and the primary side channel of the first heat exchanger and the primary side channel of the second heat exchanger are arranged on the primary side pipeline in the first connection mode through the controllable switch module. In this case, the refrigerant temperature of the primary side pipeline is appropriate, which can provide sufficient cold energy for the first heat exchanger, so that the first heat exchanger can transfer the cold energy to the refrigerant of the liquid cooling module through heat exchange, thereby sufficiently cooling the elements with relatively high heat generation in the electronic device. Moreover, the liquid cooling module is configured to cool the devices with relatively high heat generation in the electronic device, and the air cooling module is configured to cool the elements with relatively low heat generation in the electronic device, so that the refrigerant of the primary side pipeline entering the second heat exchanger can meet the cold energy demand of the second heat exchanger for the refrigerant of the air cooling module, so that the air cooling module has a better cooling effect on the devices with relatively low heat generation in the electronic device.

[0028] When the cooling system operates in the first target cooling mode, the primary side passage inlet measured temperature and / or the primary side passage outlet measured temperature do not satisfy the relaxed heat exchange constraint condition, indicating that the refrigerant temperature in the primary side pipeline is not low enough, resulting in insufficient heat exchange capacity of the first heat exchanger, and the liquid cooling module is difficult to sufficiently cool the elements with high heat dissipation in the electronic device. Considering that the heat exchange capacity of the first heat exchanger in the first target cooling mode is higher than that of the first heat exchanger in the initial cooling mode under the condition that the cooling liquid temperature in the primary side pipeline is the same, the operating mode of the cooling system can be adjusted from the initial cooling mode to the first target cooling mode, so that the primary side passage of the first heat exchanger and the primary side passage of the second heat exchanger are arranged on the primary side pipeline through the controllable switch module in the second connection mode, thereby improving the heat exchange capacity of the first heat exchanger, so that the first heat exchanger can provide sufficient cold energy for the refrigerant of the liquid cooling module, and preferentially ensure that the liquid cooling module can sufficiently cool the devices with high heat dissipation in the electronic device. At the same time, considering that the refrigerant temperature in the primary side pipeline is relatively high, the power consumption of the air cooling module can also be increased to improve the cooling capacity of the air cooling module for the elements with low heat dissipation in the electronic device.

[0029] It can be seen that the cooling system of the present application can determine whether the connection mode of the primary side passage of the first heat exchanger and the primary side passage of the second heat exchanger on the primary side pipeline needs to be adjusted through the switch control module according to whether the primary side passage inlet measured temperature and the primary side passage outlet measured temperature simultaneously satisfy the relaxed heat exchange constraint condition, thereby adaptively controlling the heat exchange capacity of the first heat exchanger and the power consumption of the air cooling module. In this way, the problem that the energy saving advantage of the liquid cooling module cannot be fully utilized due to the excessively low cooling liquid temperature can be solved without reducing the cooling liquid temperature in the primary side pipeline, and the cooling effect of the liquid cooling module and the air cooling module on the electronic device can be ensured, thereby realizing temperature decoupling of the liquid cooling module and the air cooling module, and making the liquid cooling module and the air cooling module fully exert the best cooling effect on the electronic device.

[0047] Embodiments of the present disclosure will be described below in greater detail with reference to the accompanying drawings. While certain embodiments of the present disclosure are shown in the drawings, it is understood that the present disclosure can be embodied in various forms and should not be construed as being limited to the embodiments set forth herein, but rather, these embodiments are provided so as to more completely and thoroughly understand the present disclosure. It is understood that the drawings and embodiments of the present disclosure are only for exemplary purposes and are not intended to limit the scope of protection of the present disclosure.

The term "one embodiment" means "at least one embodiment"; the term "another embodiment" means "at least one additional embodiment"; the term "some embodiments" means "at least some embodiments". Related terms are defined as follows. It should be noted that the concepts "first", "second", etc. mentioned in the present disclosure are only used to distinguish different devices, modules or units, and are not intended to limit the order or interdependence of the functions performed by these devices, modules or units.

[0050] It should be noted that the modification of "one", "multiple" mentioned in the present disclosure is illustrative and not restrictive, and those skilled in the art should understand that unless the context clearly indicates otherwise, it should be understood as "one or more".

[0051] With the rapid development of high-density computing, the servers in the data center (Internet Data Center, IDC) have higher and higher cooling requirements. The traditional air cooling commonly used at present gradually cannot meet the increasingly high cooling requirements of the data center. The liquid cooling technology can effectively solve the problem of insufficient server cooling capacity and effectively reduce the PUE value. Therefore, more and more people pay attention to the liquid cooling technology.

[0052] At present, the liquid cooling technology is divided into immersion liquid cooling technology and cold plate liquid cooling technology. The cold plate liquid cooling technology is a technology that brings cooling liquid to the main heat generating elements of the server through a cold plate device, so that the cooling liquid exchanges heat with the main heat generating elements of the server to take away the heat of the main heat generating elements of the server. Since the cold plate device mainly covers the main heat generating elements of the server, it cannot cover all the heat generating units in the server, and therefore, air cooling is still needed to assist in cooling the server.

[0053] For example, for the server internal hard disk, memory and other low heat devices, no cold plate device is set, and the cold plate type liquid cooling technology cannot be used to cool the hard disk, memory and other low heat devices, and the conventional air cooling air conditioning system and server fan is still needed to take out the heat outside the server. Usually, the server fan can be matched with a liquid cooling backplane door (i.e. backplane door type heat exchanger) with refrigerated water inside, which is used to solve the heat dissipation problem of low heat devices that cannot be solved by the cooling device.

[0054] Therefore, for the current cold machine room, usually two sets of refrigeration systems or pipelines are included, one set is responsible for the heat dissipation of the liquid cooling part, and the other set is responsible for the heat dissipation of the air cooling part. Moreover, for the existing data center machine room, usually two sets of refrigeration systems are included, one set is responsible for the heat dissipation of the liquid cooling part, and the other set is responsible for the heat dissipation of the air cooling part. However, air cooling requires low temperature water, which leads to the requirement of the cooling system for the temperature of the primary side cooling liquid being relatively low, so that the energy consumption of the cooling system increases, and therefore, the energy saving advantage of the liquid cooling module cannot be fully played, which is not conducive to the overall energy efficiency improvement of the cooling system.

[0055] Figure 1 The structure schematic diagram of the cooling system of the embodiment of the present application is shown. As shown in Figure 1 The cooling system 100 of the embodiment of the present application includes a first heat exchanger 101A, a second heat exchanger 102A, a liquid cooling module 101B, an air cooling module 102B, a primary side pipeline and a controllable switch module.

[0056] As shown in Figure 1 The first heat exchanger 101A and the second heat exchanger 102A both have a primary side channel and a secondary side channel, and both are communicated with the primary side pipeline 103. In this way, the refrigerant of the primary side pipeline 103 can enter the primary side channel of the first heat exchanger 101A and the primary side channel of the second heat exchanger 102A.

[0057] As shown in Figure 1 The secondary side channel of the first heat exchanger 101A is communicated with the liquid cooling module 101B. In this case, the cooling liquid in the primary side channel of the first heat exchanger 101A can transfer cold energy to the cooling liquid of the liquid cooling module 101B by heat exchange, so that the liquid cooling module 101B can cool the elements with relatively high heat of the electronic equipment.

[0058] As shown in Figure 1 The secondary side channel of the second heat exchanger 102A is communicated with the air cooling module 102B. In this case, the cooling liquid in the primary side channel of the second heat exchanger 102A can transfer cold energy to the cooling liquid of the air cooling module 102B by heat exchange, so that the air cooling module 102B can cool the elements with relatively high heat of the electronic equipment.

[0059] AsFigure 1 As shown, the controllable switch module of this application embodiment can switch the operating mode of the cooling system. It can be installed on the primary side pipeline 103 to switch the connection mode of the primary side channel of the first heat exchanger 101A and the primary side channel of the second heat exchanger 102A.

[0060] like Figure 1 As shown, when the cooling system 100 is running in the initial cooling mode, the first heat exchanger 101A and the second heat exchanger 102A are connected to the primary side pipeline 103 in a first connection manner through a controllable switch module. The measured temperature at the inlet of the primary side channel of the first heat exchanger 101A and the measured temperature at the outlet of the primary side channel of the first heat exchanger 101A simultaneously satisfy the relaxed heat transfer constraint condition.

[0061] like Figure 1 As shown, when the cooling system 100 is running in the first target cooling mode, the first heat exchanger 101A and the second heat exchanger 102A are connected to the primary side pipeline 103 in a second connection manner through a controllable switch module. The measured temperature at the inlet of the primary side channel and / or the measured temperature at the outlet of the primary side channel do not meet the relaxed heat transfer constraint conditions.

[0062] In this embodiment, both the inlet and outlet temperatures of the primary side channel simultaneously meet the relaxed heat transfer constraint conditions. In this case, the inlet and outlet temperatures of the primary side channel can maintain the heat dissipation of the liquid cooling module for components of electronic devices that generate significant heat.

[0063] like Figure 1 As shown, in order to ensure that the liquid cooling module 101B and the temperature module can have a better cooling effect on the electronic equipment, in this embodiment of the application, when the coolant temperature of the primary side pipeline is the same, the heat exchange capacity of the first heat exchanger 101A in the first target cooling mode is higher than that of the first heat exchanger 101A in the initial cooling mode, and the power consumption of the air cooling module 102B in the first target cooling mode is higher than that of the air cooling module 102B in the initial cooling mode.

[0064] like Figure 1As shown, when the cooling system 100 operates in the initial cooling mode, the primary side channel inlet measured temperature and the primary side channel outlet measured temperature satisfy the relaxation heat exchange constraint condition at the same time, and the primary side channel of the first heat exchanger 101A and the primary side channel of the second heat exchanger 102A are arranged on the primary side pipeline 103 in the first connection mode through the controllable switch module. In this case, the cooling liquid temperature of the primary side pipeline 103 is relatively appropriate, and sufficient cold energy can be provided for the first heat exchanger 101A, so that the first heat exchanger 101A can transfer the cold energy to the refrigerant of the liquid cooling module 101B through heat exchange, thereby sufficiently cooling the elements with relatively high heat generation in the electronic device. Therefore, the first heat exchanger 101A and the second heat exchanger 102A are arranged on the primary side pipeline 103 in the first connection mode through the controllable switch module, so that the first heat exchanger 101A can meet the heat exchange demand of the liquid cooling module 101B under a relatively low heat exchange capacity.

[0065] Moreover, as Figure 1 shown, the liquid cooling module 101B is used to cool the devices with relatively high heat generation in the electronic device, and has relatively high cold energy demand, the air cooling module 102B is used to cool the elements with relatively low heat generation in the electronic device, and has relatively low cold energy demand, and the refrigerant temperature of the primary side pipeline 103 can meet the cold energy demand of the liquid cooling module 101B. Therefore, the refrigerant of the primary side pipeline 103 enters the second heat exchanger 102A, which can meet the cold energy demand of the refrigerant of the air cooling module 102B, so that the air cooling module 102B has good cooling effect on the devices with relatively low heat generation in the electronic device, thereby realizing temperature decoupling of the liquid cooling module 101B and the air cooling module 102B, and successfully achieving the best cooling effect of the liquid cooling module 101B and the air cooling module 102B on the electronic device.

[0066] As Figure 1As shown, when the cooling system 100 operates in the first target cooling mode, the primary side passage inlet measured temperature and / or the primary side passage outlet measured temperature does not satisfy the relaxed heat exchange constraint condition, indicating that the refrigerant temperature in the primary side pipeline 103 is not low enough, and the cooling liquid in the primary side pipeline 103 is difficult to provide sufficient cold energy for the first heat exchanger 101A, so that the heat exchange capacity of the first heat exchanger 101A is insufficient, causing the liquid cooling module 101B to be difficult to fully cool the electronic device components with relatively high heat dissipation. Considering that the heat exchange capacity of the first heat exchanger 101A in the first target cooling mode is higher than that of the first heat exchanger 101A in the initial cooling mode under the condition that the cooling liquid temperature in the primary side pipeline is the same, the operating mode of the cooling system 100 can be adjusted from the initial cooling mode to the first target cooling mode, so that the first heat exchanger 101A and the second heat exchanger 102A are arranged on the primary side pipeline 103 in the second connection mode through the controllable switch module, thereby improving the heat exchange capacity of the first heat exchanger 101A, so that the first heat exchanger 101A can provide sufficient cold energy for the refrigerant of the liquid cooling module 101B, and preferentially ensure that the liquid cooling module 101B can fully cool the electronic device components with relatively high heat dissipation.

[0067] At the same time, as shown in Figure 1 Considering that the refrigerant temperature in the primary side pipeline 103 is relatively high, the power consumption of the air cooling module 102B can also be increased to improve the cooling capacity of the air cooling module 102B for the electronic device components with relatively low heat dissipation. In this way, the cooling liquid temperature in the primary side pipeline 103 does not need to be reduced, and the air cooling module 102B can also cool the electronic device components with relatively low heat dissipation at a lower power consumption, realizing temperature decoupling of the liquid cooling module 101B and the air cooling module 102B in the initial cooling mode, so that the liquid cooling module 101B and the air cooling module 102B fully exert the best cooling effect on the electronic device.

[0068] As can be seen from the above, Figure 1As shown, the cooling system 100 of the embodiment of the present application can determine whether the connection mode of the primary side channel of the first heat exchanger 101 A and the primary side channel of the second heat exchanger 102 A on the primary side pipeline 103 needs to be adjusted by the switch control module according to whether the primary side channel inlet measured temperature and the primary side channel outlet measured temperature satisfy the relaxation heat exchange constraint condition at the same time, so as to adaptively control the heat exchange capacity of the first heat exchanger 101 A and the energy consumption of the air cooling module 102 B. In this way, the problem that the energy saving advantage of the liquid cooling module 101 B cannot be fully exerted due to the too low cooling liquid temperature can be reduced without reducing the cooling liquid temperature in the primary side pipeline 103, and the cooling effect of the liquid cooling module 101 B and the air cooling module 102 B on the electronic device can be ensured, so as to realize the temperature decoupling of the liquid cooling module 101 B and the air cooling module 102 B, and make the liquid cooling module 101 B and the air cooling module 102 B fully exert the best cooling effect on the electronic device.

[0069] In a possible implementation, the first connection mode and the second connection mode of the embodiment of the present application can have two possible combination modes. The first combination mode includes that the first connection mode is the first series connection mode and the second connection mode is the parallel connection mode; and the second combination mode includes that the first connection mode is the parallel connection mode and the second connection mode is the second series connection mode.

[0070] The controllable switch module of the embodiment of the present application includes a first controllable switch module, which can realize the switching between the first connection mode and the second connection mode. The first series connection mode can include that the primary side channel of the air cooling module and the primary side channel of the liquid cooling module are sequentially connected in series on the primary side pipeline through the first controllable switch module along the cooling liquid flow direction of the primary side pipeline, and the second series connection mode includes that the primary side channel of the liquid cooling module and the primary side channel of the air cooling module are sequentially connected in series on the primary side pipeline through the first controllable switch module along the cooling liquid flow direction of the primary side pipeline.

[0071] As shown in the figure, Figure 1 The first controllable switch module can include a first primary side controllable switch C11, a second primary side controllable switch C12, a third primary side controllable switch C13 and a fourth primary side controllable switch C14. Here, the first primary side controllable switch C11, the second primary side controllable switch C12, the third primary side controllable switch C13 and the fourth primary side controllable switch C14 can be conventional controllable three-way valves.

[0072] As shown in the figure, Figure 1As shown, the inlet of the first primary-side controllable switch C11 is communicated with the primary-side pipeline 103, the outlet of the first primary-side controllable switch C11 is communicated with the inlet of the second primary-side controllable switch C12 through the primary-side passage of the first heat exchanger 101A, the outlet of the second primary-side controllable switch C12 is respectively communicated with the primary-side pipeline 103 and the inlet of the third primary-side controllable switch C13, the inlet of the third primary-side controllable switch C13 is communicated with the primary-side pipeline 103, the outlet of the third primary-side controllable switch C13 is communicated with the inlet of the fourth primary-side controllable switch C14 through the primary-side passage of the second heat exchanger 102A, and the outlet of the fourth primary-side controllable switch C14 is respectively communicated with the inlet of the first primary-side controllable switch C11 and the primary-side pipeline 103.

[0073] Figure 2A A schematic diagram of pipeline connection of the cooling system in the first series connection mode is shown. Figure 2A As shown, in the first series connection mode, the first primary-side controllable switch C11 disconnects the primary-side pipeline 103 and the inlet of the primary-side passage of the first heat exchanger 101A, the third primary-side controllable switch C13 connects the primary-side pipeline 103 and the inlet of the primary-side passage of the second heat exchanger 102A, and the second primary-side controllable switch C12 and the third primary-side controllable switch C13 disconnect the outlet of the primary-side passage of the first heat exchanger 101A and the inlet of the primary-side passage of the second heat exchanger 102A, so that the cooling liquid in the primary-side pipeline 103 can directly enter the primary-side passage of the second heat exchanger 102A and exchange heat with the refrigerant in the secondary-side passage of the second heat exchanger 102A entered by the air cooling module 102B.

[0074] Moreover, as shown, Figure 2A the fourth primary-side controllable switch C14 can disconnect the outlet of the primary-side passage of the second heat exchanger 102A and the primary-side pipeline 103, the fourth primary-side controllable switch C14 and the first primary-side controllable switch C11 can also connect the outlet of the primary-side passage of the second heat exchanger 102A and the inlet of the primary-side passage of the first heat exchanger 101A, and the second primary-side controllable switch C12 connects the outlet of the primary-side passage of the first heat exchanger 101A and the primary-side pipeline 103, so that the refrigerant flowed out of the primary-side passage of the second heat exchanger 102A can enter the primary-side passage of the first heat exchanger 101A through the fourth primary-side controllable switch C14 and the first primary-side controllable switch C11, exchange heat with the refrigerant in the secondary-side passage of the first heat exchanger 101A entered by the liquid cooling module 101B, and then return to the primary-side pipeline 103 through the second primary-side controllable switch C12.

[0075] As shown, Figure 2AAs shown, in the first series connection mode, the refrigerant in the primary side pipeline 103 can first enter the refrigerant heat exchange between the second heat exchanger 102A and the air cooling module 102B, then enter the refrigerant heat exchange between the first heat exchanger 101A and the liquid cooling module 101B, and finally return to the primary side pipeline 103. In this case, the refrigerant in the primary side pipeline 103 provides a higher cooling capacity for the air cooling module 102B than for the liquid cooling module 101B.

[0076] When the primary side channel inlet measured temperature and the primary side channel outlet measured temperature satisfy the relaxation heat exchange constraint condition, as shown in the following formula (1), the primary side channel inlet measured temperature and the primary side channel outlet measured temperature satisfy the relaxation heat exchange constraint condition. Figure 2A As shown, the heat exchange capacity of the first heat exchanger 101A can meet the cooling capacity requirement of the liquid cooling module 101B. Since the refrigerant in the primary side pipeline 103 can provide a higher cooling capacity for the air cooling module 102B than for the liquid cooling module 101B, and the liquid cooling module 101B is used to cool the device with a relatively high heat generation of the electronic equipment, and the air cooling module 102B is used to cool the element with a relatively low heat generation of the electronic equipment, the heat exchange capacity of the second heat exchanger 102A is sufficient to meet the cooling capacity requirement of the air cooling module 102B, so that the air cooling module 102B can sufficiently cool the element with a relatively low heat generation of the electronic equipment.

[0077] Figure 2B A schematic diagram of the pipeline connection of the cooling system in the parallel connection mode is shown. As shown in the following figure, Figure 2B As shown, in the parallel connection mode, the first primary side controllable switch C11 connects the primary side pipeline 103 and the primary side channel inlet of the first heat exchanger 101A, and the third primary side controllable switch C13 connects the primary side pipeline 103 and the primary side channel inlet of the second heat exchanger 102A. Therefore, the cooling liquid in the primary side pipeline 103 can enter the primary side channel of the first heat exchanger 101A and the primary side channel of the second heat exchanger 102A, respectively, and the refrigerant in the primary side channel of the first heat exchanger 101A can exchange heat with the refrigerant in the secondary side channel of the second heat exchanger 102A entered by the air cooling module 102B.

[0078] As shown in the following figure, Figure 2BAs shown, the liquid cooling module 101B enters the secondary side channel of the first heat exchanger 101A and exchanges heat with the refrigerant liquid in the primary side channel of the first heat exchanger 101A, so that the liquid cooling module 101B can obtain cold energy from the first heat exchanger 101A to cool the device of the electronic equipment with high heat dissipation; and the air cooling module 102B enters the secondary side channel of the second heat exchanger 102A and exchanges heat with the refrigerant liquid in the primary side channel of the second heat exchanger 102A, so that the air cooling module 102B can obtain cold energy from the second heat exchanger 102A to cool the element of the electronic equipment with high heat dissipation.

[0079] Moreover, as shown in Figure 2B , the first primary side controllable switch C11 and the fourth primary side controllable switch C14 disconnect the primary side channel inlet of the first heat exchanger 101A and the primary side channel outlet of the second heat exchanger 102A, and the second primary side controllable switch C12 and the third primary side controllable switch C13 disconnect the primary side channel outlet of the first heat exchanger 101A and the primary side channel inlet of the second heat exchanger 102A, so that the cooling liquid flowing out of the primary side channel of the first heat exchanger 101A and the cooling liquid flowing out of the primary side channel of the second heat exchanger 102A can directly enter the primary side pipeline 103.

[0080] As can be seen, in the parallel connection mode, as shown in Figure 2B , the refrigerant liquid of the primary side pipeline 103 can simultaneously enter the primary side channel of the first heat exchanger 101A and the primary side channel of the second heat exchanger 102A, and then return to the primary side pipeline 103 at the same time. In this case, the cold energy provided by the refrigerant liquid of the primary side pipeline 103 for the air cooling module 102B is the same as the cold energy provided by the refrigerant liquid of the primary side pipeline 103 for the liquid cooling module 101B. In the first series connection mode, the cold energy provided by the refrigerant liquid of the primary side pipeline 103 for the air cooling module 102B is higher than the cold energy provided by the refrigerant liquid of the primary side pipeline 103 for the liquid cooling module 101B, so that in the case that the cooling liquid temperature of the primary side pipeline is the same, the heat exchange capacity of the first heat exchanger 101A in the first target cooling mode is higher than the heat exchange capacity of the first heat exchanger 101A in the initial cooling mode.

[0081] For example, when the first connection mode is the first series connection mode and the second connection mode is the second series connection mode, if the primary side channel inlet measured temperature and / or the primary side channel outlet measured temperature does not satisfy the relaxation heat exchange constraint condition, as shown in Figure 2A and Figure 2BAs shown, the cooling capacity of the first heat exchanger 101A can be improved by changing the operation mode of the cooling system 100 from the initial cooling mode to the first target cooling mode, so as to meet the cooling capacity requirement of the liquid cooling module 101B, so that the liquid cooling module 101B can sufficiently cool the electronic device with high heat generation.

[0082] Figure 2C The pipe connection schematic diagram of the cooling system in the second series connection mode is shown. As shown in the figure, Figure 2C As shown, in the second series connection mode, the first primary controllable switch C11 connects the primary pipe 103 and the primary side channel inlet of the first heat exchanger 101A, the third primary controllable switch C13 disconnects the primary pipe 103 and the primary side channel inlet of the second heat exchanger 102A, and the first primary controllable switch C1 and the fourth primary controllable switch C14 can also disconnect the primary side channel inlet of the first heat exchanger 101A and the primary side channel outlet of the second heat exchanger 102A. Therefore, the cooling liquid in the primary pipe 103 can directly enter the primary side channel of the first heat exchanger 101A and exchange heat with the refrigerant in the secondary side channel of the liquid cooling module 101B entering the first heat exchanger 101A.

[0083] Moreover, as shown in the figure, Figure 2C As shown, the second primary controllable switch C12 disconnects the primary side channel outlet of the first heat exchanger 101A and the primary pipe 103, the second primary controllable switch C12 and the third primary controllable switch C13 connect the primary side channel outlet of the first heat exchanger 101A and the primary side channel inlet of the second heat exchanger 102A, and the fourth primary controllable switch C14 connects the primary side channel outlet of the second heat exchanger 102A and the primary pipe 103. Therefore, the refrigerant flowing out of the primary side channel of the first heat exchanger 101A can enter the primary side channel of the second heat exchanger 102A through the second primary controllable switch C12 and the third primary controllable switch C13, and exchange heat with the refrigerant in the secondary side channel of the air cooling module 102B entering the second heat exchanger 102A, and then return to the primary pipe 103 through the fourth primary controllable switch C14.

[0084] As shown in the figure, Figure 2C As shown, the refrigerant in the primary pipe 103 can first exchange heat with the refrigerant of the liquid cooling module 101B in the first heat exchanger 101A, then exchange heat with the refrigerant of the air cooling module 102B in the second heat exchanger 102A, and finally return to the primary pipe 103. In this case, the cooling capacity provided by the refrigerant in the primary pipe 103 for the liquid cooling module 101B is higher than the cooling capacity provided by the refrigerant in the primary pipe 103 for the air cooling module 102B.

[0085] As shown in the examples, Figure 2B and Figure 2C When the parallel connection mode, the refrigerant in the primary side pipeline 103 provides the cooling capacity for the air-cooled module 102B is higher than the refrigerant in the primary side pipeline 103 provides the cooling capacity for the liquid-cooled module 101B, when the second series connection mode, the refrigerant in the primary side pipeline 103 provides the cooling capacity for the liquid-cooled module 101B is higher than the refrigerant in the primary side pipeline 103 provides the cooling capacity for the air-cooled module 102B, therefore, when the cooling liquid temperature of the primary side pipeline is the same, the heat exchange capacity of the first heat exchanger 101A in the first target cooling mode is higher than the heat exchange capacity of the first heat exchanger 101A in the initial cooling mode.

[0086] As an example, when the first connection mode is the parallel connection mode, the second connection mode is the second series connection mode, if the primary side channel inlet measured temperature and the primary side channel outlet measured temperature do not meet the relaxation heat exchange constraint condition, the heat exchange capacity of the first heat exchanger is difficult to meet the cooling capacity demand of the liquid-cooled module, the operation mode of the cooling system can be changed from the initial cooling mode to the first target cooling mode to improve the heat exchange capacity of the first heat exchanger to meet the cooling capacity demand of the liquid-cooled module, so that the liquid-cooled module can fully cool the device with high heat dissipation of electronic equipment.

[0087] In some possible implementations, when the cooling system operates in the initial cooling mode, the primary side channel flow of the first heat exchanger is less than the preset maximum flow, when the cooling system operates in the first target cooling mode, the primary side channel flow of the first heat exchanger is greater than or equal to the preset maximum flow.

[0088] In actual application, if the primary side channel inlet measured temperature and / or the primary side channel outlet measured temperature does not meet the relaxation heat exchange constraint condition, it indicates that the cooling liquid of the primary side channel of the first heat exchanger is difficult to provide sufficient cooling capacity for the liquid-cooled module, therefore, the primary side channel flow of the first heat exchanger can be increased to improve the cooling capacity of the primary side pipeline for the first heat exchanger.

[0089] In the process, if the first heat exchanger one side passage flow is less than the preset maximum flow, and the one side passage inlet measured temperature and the one side passage outlet measured temperature meet the relaxed heat exchange constraint condition at the same time, it indicates that the first heat exchanger one side passage cooling liquid can provide sufficient cooling capacity for the liquid cooling module, and thus the operation mode of the cooling system can be maintained in the initial cooling mode. If the first heat exchanger one side passage flow is equal to the preset maximum flow, and the one side passage inlet measured temperature and / or the one side passage outlet measured temperature still do not meet the relaxed heat exchange constraint condition, if the first heat exchanger one side passage cooling liquid flow continues to increase, it will be possible to cause an unsafe accident, and thus the operation mode of the cooling system can be switched from the initial cooling mode to the first target cooling mode, so that the first heat exchanger and the second heat exchanger are arranged on the primary side pipeline in the second connection mode through the controllable switch module, to preferentially ensure the cooling effect of the liquid cooling module on the electronic equipment components with high heat generation.

[0090] Moreover, when the cooling system operates in the initial cooling mode, the first heat exchanger one side passage cooling liquid can already provide sufficient cooling capacity for the liquid cooling module, and thus when the cooling system operates in the initial cooling mode, if the first heat exchanger one side passage flow is less than the preset maximum flow, the liquid cooling module can cool the electronic equipment components with high heat generation in the case of less cooling capacity of the first heat exchanger, thereby improving the energy efficiency of the cooling system.

[0091] In some possible implementations, the one side passage inlet measured temperature and the one side passage outlet measured temperature also meet the strict heat exchange constraint condition when the cooling system operates in the initial cooling mode, and the one side passage inlet measured temperature and / or the one side passage outlet measured temperature do not meet the strict heat exchange constraint condition when the cooling system operates in the first target cooling mode.

[0092] In actual applications, the one side passage inlet measured temperature and the one side passage outlet measured temperature meeting the strict heat exchange constraint condition are relatively low (compared with the one side passage inlet measured temperature and the one side passage outlet measured temperature meeting the relaxed heat exchange constraint condition), and the one side passage inlet measured temperature and the one side passage outlet measured temperature meeting the relaxed heat exchange constraint condition are relatively high.

[0093] When the cooling system operates in the first target cooling mode, it can be determined whether the primary-side passage inlet measured temperature and the primary-side passage outlet measured temperature simultaneously satisfy the strict heat exchange constraint condition. Since the primary-side passage inlet measured temperature and the primary-side passage outlet measured temperature satisfying the strict heat exchange constraint condition are relatively low, when the strict heat exchange constraint condition is simultaneously satisfied, it indicates that the primary-side passage cooling liquid of the first heat exchanger can already provide sufficient cooling capacity for the liquid cooling module. Therefore, the operating mode of the cooling system is switched back to the initial cooling mode from the first target cooling mode. When the primary-side passage inlet measured temperature and / or the primary-side passage outlet measured temperature does not satisfy the strict heat exchange constraint condition, it indicates that the primary-side passage cooling liquid of the first heat exchanger cannot provide sufficient cooling capacity for the liquid cooling module.

[0094] To ensure the running stability of the liquid cooling module in the initial operating mode, when the cooling system operates in the initial cooling mode, the time length during which the primary-side passage inlet measured temperature satisfies the strict heat exchange constraint condition is greater than or equal to a preset time length, and the time length during which the primary-side passage outlet measured temperature satisfies the strict heat exchange constraint condition is greater than or equal to a preset time length. When the cooling system operates in the first target cooling mode, the time length during which the primary-side passage inlet measured temperature does not satisfy the strict heat exchange constraint condition is greater than or equal to a preset time length, and / or, the time length during which the primary-side passage outlet measured temperature does not satisfy the strict heat exchange constraint condition is greater than or equal to a preset time length.

[0095] In actual applications, when the cooling system operates in the first target cooling mode, it can be determined whether the time length during which the primary-side passage inlet measured temperature satisfies the strict heat exchange constraint condition is greater than or equal to a preset time length, and simultaneously determine whether the time length during which the primary-side passage outlet measured temperature does not satisfy the strict heat exchange constraint condition is greater than or equal to a preset time length.

[0096] If the time length during which the primary-side passage inlet measured temperature satisfies the strict heat exchange constraint condition is greater than or equal to a preset time length, and the time length during which the primary-side passage outlet measured temperature does not satisfy the strict heat exchange constraint condition is greater than or equal to a preset time length, it indicates that, after the operating mode of the cooling system is switched back to the initial cooling mode from the first target cooling mode, the primary-side passage cooling liquid of the first heat exchanger can provide higher cooling capacity for the liquid cooling module.

[0097] Meanwhile, when the operation mode of the cooling system is switched back from the first target cooling mode to the initial cooling mode, the flow of the primary side passage of the first heat exchanger can also be reduced, so that the flow of the primary side passage of the first heat exchanger is less than the preset maximum flow. Since the primary side passage inlet measured temperature and the primary side passage outlet measured temperature that meet the strict heat exchange constraint condition are relatively low, and the primary side passage inlet measured temperature and the primary side passage outlet measured temperature that meet the relaxed heat exchange constraint condition are relatively high, when the operation mode of the cooling system is switched back from the first target cooling mode to the initial cooling mode, even if the flow of the primary side passage of the first heat exchanger is reduced, the primary side passage inlet measured temperature and the primary side passage outlet measured temperature can still meet the relaxed heat exchange constraint condition at the same time, so that the primary side passage of the first heat exchanger provides sufficient cooling capacity for the liquid cooling module.

[0098] If the time length during which the primary side passage inlet measured temperature meets the strict heat exchange constraint condition is less than the preset time length, and the time length during which the primary side passage outlet measured temperature does not meet the strict heat exchange constraint condition is less than the preset time length, it indicates that if the flow of the primary side passage of the first heat exchanger is reduced after the operation mode of the cooling system is switched back from the first target cooling mode to the initial cooling mode, the primary side passage inlet measured temperature and the primary side passage outlet measured temperature can not be able to meet the relaxed heat exchange constraint condition at the same time, and therefore, the cooling system can be maintained to operate in the first target cooling mode.

[0099] In order to understand the relaxed heat exchange constraint condition and the strict heat exchange constraint condition of the embodiments of the present application, the relaxed heat exchange constraint condition and the strict heat exchange constraint condition are illustrated below respectively.

[0100] The relaxed heat exchange constraint condition of the embodiments of the present application includes the relaxed constraint condition of the primary side passage inlet temperature and the relaxed constraint condition of the primary side passage outlet temperature. Here, the relaxed constraint condition of the primary side passage inlet temperature can include that the primary side passage inlet measured temperature matches the first preset temperature of the primary side passage inlet of the first heat exchanger, and the relaxed constraint condition of the primary side passage outlet temperature can include that the primary side passage outlet measured temperature matches the first preset temperature of the primary side passage outlet of the first heat exchanger.

[0101] When the primary-side channel inlet measured temperature matches the first preset temperature of the primary-side channel inlet of the first heat exchanger, it indicates that the temperature of the primary-side pipeline at the primary-side channel inlet of the first heat exchanger meets the requirement. When the primary-side channel outlet measured temperature matches the first preset temperature of the primary-side channel outlet of the first heat exchanger, it indicates that the temperature of the primary-side pipeline at the primary-side channel outlet of the first heat exchanger meets the requirement. That is, when the primary-side channel inlet and outlet measured temperatures of the primary-side pipeline at the first heat exchanger both meet the requirement, the cooling liquid of the primary-side pipeline can provide sufficient cold energy for the first heat exchanger to exchange heat with the refrigerant of the liquid cooling module to meet the cold energy requirement of the liquid cooling module. If one of the primary-side channel inlet and outlet measured temperatures of the primary-side pipeline at the first heat exchanger does not meet the requirement, it indicates that the cooling liquid of the primary-side pipeline is difficult to provide sufficient cold energy for the first heat exchanger to exchange heat with the refrigerant of the liquid cooling module.

[0102] For example, the first preset temperature of the primary-side channel inlet of the first heat exchanger is determined by the preset temperature of the secondary-side channel outlet of the first heat exchanger and the preset heat exchanger end difference of the first heat exchanger, and the first preset temperature of the primary-side channel outlet of the first heat exchanger is determined by the preset temperature of the secondary-side channel inlet of the first heat exchanger and the preset heat exchanger end difference of the first heat exchanger. It can be seen that the first preset temperature of the primary-side channel inlet of the first heat exchanger and the first preset temperature of the primary-side channel outlet of the first heat exchanger can be designed based on the heat exchange principle in the embodiments of the present application.

[0103] For example, the primary-side channel inlet measured temperature is T1, the first preset temperature of the primary-side channel inlet of the first heat exchanger is T1', the preset temperature of the secondary-side channel outlet of the first heat exchanger is T2', and the preset heat exchanger end difference of the first heat exchanger is δT. The first preset temperature of the primary-side channel inlet of the first heat exchanger is T1' = T2' + δT. The preset temperature of the secondary-side channel outlet of the first heat exchanger is T2' = 30°C. The preset heat exchanger end difference of the first heat exchanger is δT = 5°C. 设1 If T1 = T1', the primary-side channel inlet measured temperature T1 matches the first preset temperature of the primary-side channel inlet of the first heat exchanger T1'. If T1 = T1', the primary-side channel inlet measured temperature T1 matches the first preset temperature of the primary-side channel inlet of the first heat exchanger T1'.

[0104] The primary-side channel outlet measured temperature is T2, the first preset temperature of the primary-side channel inlet of the first heat exchanger is T1', the preset temperature of the secondary-side channel inlet of the first heat exchanger is T2', and the preset heat exchanger end difference of the first heat exchanger is δT. The first preset temperature of the primary-side channel inlet of the first heat exchanger is T1' = T2' + δT. The preset temperature of the secondary-side channel inlet of the first heat exchanger is T2' = 30°C. If T2 = T1', the primary-side channel inlet measured temperature T2 matches the first preset temperature of the primary-side channel inlet of the first heat exchanger T1'. If T2 = T1', the primary-side channel inlet measured temperature T2 matches the first preset temperature of the primary-side channel inlet of the first heat exchanger T1'.

[0105] ​​​​The strict heat exchange constraint condition of the embodiment of the application includes a strict constraint condition of the inlet temperature of the primary side channel and a strict constraint condition of the outlet temperature of the primary side channel. The strict constraint condition of the inlet temperature of the primary side channel includes that the inlet measurement temperature of the primary side channel matches the second preset temperature of the inlet of the primary side channel of the first heat exchanger, and the strict constraint condition of the outlet temperature of the primary side channel includes that the outlet measurement temperature of the primary side channel matches the second preset temperature of the outlet of the primary side channel of the first heat exchanger.

[0106] In actual application, when the inlet measurement temperature of the primary side channel matches the second preset temperature of the inlet of the primary side channel of the first heat exchanger, it indicates that the temperature of the primary side channel at the inlet of the first heat exchanger meets the requirement. When the outlet measurement temperature of the primary side channel matches the second preset temperature of the outlet of the primary side channel of the first heat exchanger, it indicates that the temperature of the primary side channel at the outlet of the first heat exchanger meets the requirement. That is to say, when the inlet and outlet measurement temperatures of the primary side channel at the first heat exchanger both meet the requirement, the cooling liquid of the primary side channel can provide sufficient cold energy for the first heat exchanger to exchange heat with the refrigerant of the liquid cooling module to meet the cold energy requirement of the liquid cooling module. If one of the inlet and outlet measurement temperatures of the primary side channel at the first heat exchanger does not meet the requirement, it indicates that the cooling liquid of the primary side channel is difficult to provide sufficient cold energy for the first heat exchanger to exchange heat with the refrigerant of the liquid cooling module.

[0107] The second preset temperature of the inlet of the primary side channel of the first heat exchanger is less than the first preset temperature of the inlet of the primary side channel of the first heat exchanger, and the second preset temperature of the outlet of the primary side channel of the first heat exchanger is less than the first preset temperature of the outlet of the primary side channel of the first heat exchanger. In this case, for the same temperature of the inlet measurement temperature of the primary side channel, it is easier to match the first preset temperature of the inlet of the primary side channel of the first heat exchanger, and not easy to match the second preset temperature of the inlet of the primary side channel of the first heat exchanger. At the same time, for the same temperature of the outlet measurement temperature of the primary side channel, it is easier to match the first preset temperature of the outlet of the primary side channel of the first heat exchanger, and not easy to match the second preset temperature of the outlet of the primary side channel of the first heat exchanger.

[0108] It can be seen that the embodiments of the present application control the first preset temperature of the inlet of the primary side passage of the first heat exchanger and the second preset temperature of the outlet of the primary side passage of the first heat exchanger, so that the constraint ability of the strict heat exchange constraint condition is stronger than the constraint ability of the relaxed heat exchange constraint condition. In this case, when the cooling system operates in the first target cooling mode, if the primary side passage inlet measured temperature and the primary side passage outlet measured temperature meet the strict heat exchange constraint condition, the cooling liquid of the primary side pipeline can provide the first heat exchanger with surplus cooling capacity at the preset maximum flow rate. In this case, the running mode of the cooling system is switched from the first target cooling mode to the initial cooling mode, and the primary side passage flow rate of the first heat exchanger is reduced, and the primary side passage inlet measured temperature and the primary side passage outlet measured temperature can still meet the relaxed heat exchange constraint condition.

[0109] For example, when the preset heat exchanger end difference compensation parameter of the first heat exchanger represents a preset heat exchanger end difference increment δT 设2 of the first heat exchanger, the second preset temperature of the inlet of the primary side passage of the first heat exchanger is If the primary side passage inlet measured temperature matches the first preset temperature of the inlet of the primary side passage of the first heat exchanger .

[0110] When the second preset temperature of the inlet of the primary side passage of the first heat exchanger is If the primary side passage inlet measured temperature matches the first preset temperature of the inlet of the primary side passage of the first heat exchanger .

[0111] It can be seen that the purpose of setting the relaxed heat exchange constraint condition and the strict heat exchange constraint condition in the embodiments of the present application is to ensure that the refrigerant of the primary side pipeline can provide the first heat exchanger with sufficient cooling capacity, so that the liquid cooling module can fully cool the devices with high heat generation of the electronic equipment.

[0112] In some possible implementation manners, as Figure 1 shown, the liquid cooling module and the air cooling module of the embodiments of the present application can be arranged centrally at a certain position of the machine room or arranged dispersedly in the rack column or the rack. The liquid cooling module 101B can be responsible for the heat dissipation problem of the devices with high heat generation such as the central processing unit (CPU) and the graphics processing unit (GPU) in the electronic equipment.

[0113] Figure 3A structural schematic diagram of the liquid cooling module of the embodiment of the present application is shown. As Figure 3 shown, the liquid cooling module 101B of the embodiment of the present application can include a first header 101-1B and a second header 101-2B and a plurality of end devices 101-3B. The secondary side passage outlet of the first heat exchanger 101A is in communication with the first header 101-1B, the first header 101-1B is connected with the first liquid cooling plate inlet of each end device 101-3B, the second liquid cooling plate outlet of each end device 101-3B is connected with the second header 101-2B, and the second header 101-2B is connected with the secondary side passage inlet of the first heat exchanger 101A.

[0114] As an example, as Figure 3 shown, the secondary side passage outlet of the first heat exchanger 101A is connected with the secondary side passage inlet of the first heat exchanger 101A through a first secondary side pipeline 101C. In this case, the first header 101-1B, the plurality of end devices 101-3B and the second header 101-2B can be arranged on the first secondary side pipeline along the flow direction of the refrigerant of the first secondary side pipeline 101C.

[0115] In actual application, as Figure 3 shown, the first heat exchanger 101A of the embodiment of the present application can be a cooling dispensing unit (CDU), and the CDU can be a centralized CDU or a decentralized CDU. When the CDU is a centralized CDU, the end device 101-3B can be a cabinet, and therefore, the refrigerant of the secondary side pipeline can be connected with the first liquid cooling interface of each cabinet through the first header 101-1B, and the second liquid cooling interface of each cabinet is connected with the second header 101-2B. When the CDU is a decentralized CDU, the CDU is located in the cabinet, and the end device 101-3B can be a server, and the first header 101-1B and the second header 101-2B can be a manifold.

[0116] As Figure 1 shown, the air cooling module 102B of the embodiment of the present application can be responsible for the low heat generating elements such as hard disks, memories and the like in the electronic equipment such as servers, and the region is not provided with a cold plate, and therefore, an air cooling air conditioner can be used as the air cooling module 102B to cool the low heat generating elements of the electronic equipment.

[0117] In an optional manner, the air cooling air conditioner of the embodiment of the present application can include a compressor refrigeration cycle system, Figure 4 A structural schematic diagram of the compressor refrigeration cycle system of the embodiment of the present application is shown. As Figure 4As shown, the air-cooled module 102B of this embodiment mainly includes a compressor 102-1B, a refrigerant pump 102-2B, a condenser 102-3B, an evaporator 102-4B, and an expansion valve K. The outlet of the compressor 102-1B is connected to the inlet of the compressor 102-1B in sequence through the condenser 102-3B, the refrigerant pump 102-2B, the expansion valve K, and the evaporator 102-4B.

[0118] For example, such as Figure 4 As shown, the secondary side outlet of the second heat exchanger 102A is connected to the secondary side inlet of the second heat exchanger 102A via the second secondary side pipe 102C. In this case, the compressor 102-1B, the refrigerant pump 102-2B, the expansion valve K, the evaporator 102-4B, and the condenser 102-3B are connected in series on the second secondary side pipe 102C.

[0119] In practical applications, such as Figure 4 As shown, in this embodiment of the application, a first controllable valve C1 can be provided between the compressor 102-1B and the condenser 102-3B, and a second controllable valve C2 can be provided between the refrigerant pump 102-2B and the expansion valve K. The inlet and outlet of the expansion valve K are connected through a third controllable valve C3. Simultaneously, the inlet of the compressor 102-1B and the outlet of the first controllable valve C1 are connected through a first check valve D1, and the inlet of the refrigerant pump 102-2B and the outlet of the second controllable valve C2 are connected through a second check valve D2.

[0120] like Figure 4 As shown, the second heat exchanger 102A in this embodiment can be a liquid fluorine heat exchanger, an air-fluorine heat exchanger, or a liquid fluorine heat exchanger, and its secondary side channel can exchange heat with the condenser 102-3B. The evaporator 102-4B can exchange heat with various heat exchangers 102D. In one example, the heat exchanger 102D is an air-fluorine heat exchanger, which can generate cold air; in another example, the heat exchanger 102D is a liquid fluorine heat exchanger, which can generate cooling water.

[0121] like Figure 4 As shown, the aforementioned air-cooled module 102B can be centrally arranged or distributed at the end of the cabinet. For the air-cooled modules 102B distributed at the end, the heat exchanger 102D can exist in the form of a cooling back panel door, that is, the refrigerant in the evaporator 102-4B is introduced into the back panel door to raise its temperature, while the air circulation achieves cooling through the back panel door.

[0122] The compressor refrigeration cycle system of this application embodiment has Figure 5A The compression cycle shown Figure 5B The two fluorine pump circulation modes shown are described in detail below.

[0123] like Figure 5AAs shown, when the compression refrigeration cycle system operates in the compression cycle mode, the second controllable valve C2 and the third controllable valve C3 are closed, the first controllable valve C1 is opened, the compressor 102-1B operates, and the fluorine pump 102-2B stops. In this case, the compressor 102-1B can deliver high-temperature and high-pressure coolant gas to the condenser 102-3B and exchange heat with the second heat exchanger 102A, so as to obtain low-temperature and high-pressure refrigerant liquid. The low-temperature and high-pressure refrigerant liquid enters the expansion valve K through the second one-way valve D2 for expansion, so as to obtain low-temperature and low-pressure refrigerant liquid. The low-temperature and low-pressure refrigerant liquid enters the evaporator 102-4B and exchanges heat with the air-fluorine heat exchanger or the liquid-fluorine heat exchanger, so as to form low-temperature and high-pressure refrigerant gas, which is then returned to the compressor 102-1B for re-compression into high-temperature and high-pressure refrigerant gas.

[0124] As shown in FIG. 1, the cooling system includes a compressor 102-1B, a fluorine pump 102-2B, a condenser 102-3B, a second heat exchanger 102A, an evaporator 102-4B, a first one-way valve D1, a second one-way valve D2, an expansion valve K, a first controllable valve C1, a second controllable valve C2, and a third controllable valve C3. Figure 5B As shown, when the compression refrigeration cycle system operates in the fluorine pump cycle mode, the first controllable valve C1 is closed, the second controllable valve C2 and the third controllable valve C3 are opened, the compressor 102-1B stops, the fluorine pump 102-2B operates, and the second one-way valve D2 and the expansion valve K are closed. In this case, the fluorine pump 102-2B can compress the coolant. The compressed coolant passes through the second controllable valve C2, the third controllable valve C3, the evaporator 102-4B, the first one-way valve D1, and the condenser 102-3B, and then returns to the fluorine pump 102-2B.

[0125] The embodiment of the present application can determine whether to use the fluorine pump cycle or the compression cycle based on the measured temperature of the coolant in the primary side channel of the second heat exchanger. For example, if the measured temperature of the coolant in the primary side channel of the second heat exchanger is lower than a set value, the fluorine pump cycle can be operated, otherwise the compression cycle can be operated.

[0126] In a possible implementation manner, Figure 6 FIG. 2 shows a connection relationship diagram of the cooling system in the second series connection mode according to an embodiment of the present application. As shown in FIG. 2, the cooling system includes a compressor 102-1B, a fluorine pump 102-2B, a condenser 102-3B, a second heat exchanger 102A, an evaporator 102-4B, a first one-way valve D1, a second one-way valve D2, an expansion valve K, a first controllable valve C1, a second controllable valve C2, and a third controllable valve C3. Figure 6As shown, the controllable switch module in this embodiment may further include a second controllable switch module, which includes a first secondary-side controllable switch C21 and a second secondary-side controllable switch C22. The air-cooled module 102B includes an air-cooled air conditioner, and the cooling system 100 further includes a third heat exchanger 103A. The third heat exchanger 103A can be a liquid refrigerant heat exchanger or other feasible heat exchangers. In this case, the inlet of the evaporator 102-4B included in the air-cooled air conditioner is connected to the outlet of the evaporator 102-4B in sequence through the first secondary-side controllable switch C21 and the primary-side channel of the third heat exchanger 103A. The outlet of the secondary-side channel of the first heat exchanger 101A is connected to the inlet of the liquid-cooled module 101B through the second secondary-side controllable switch C22 and the secondary-side channel of the third heat exchanger 103A. The outlet of the liquid-cooled module 101B is connected to the inlet of the secondary-side channel of the first heat exchanger 101A.

[0127] like Figure 6 As shown, when the cooling system 100 is running in the second target cooling mode, the first secondary side controllable switch C21 and the second secondary side controllable switch C22 are turned on. The liquid cooling module 101B and the air cooling module 102B are connected to the primary side pipeline 103 through the first controllable switch module in a first connection manner. The third connection manner is the second series connection manner.

[0128] In specific implementation, such as Figure 6 As shown, when the cooling system 100 is in the initial cooling mode, if the first connection method is the second series connection method, and the measured temperature at the primary side channel inlet and / or the measured temperature at the primary side channel outlet does not meet the relaxed heat transfer constraint condition, the heat transfer capacity of the first heat exchanger 101A has reached its maximum because, under the second series connection method, the coolant in the primary side pipe 103 first passes through the liquid cooling module 101B and then through the air cooling module 102B. In this case, the first and second secondary side controllable switches C21 and C22 can be turned on without changing the connection method of the liquid cooling module 101B and the air cooling module 102B. In this case, the operating mode of the cooling system 100 changes from the initial cooling mode to the second target cooling mode.

[0129] For example, such as Figure 6As shown, when the cooling system 100 is operating in the second target cooling mode, the refrigerant from the liquid-cooled module 101B flowing out of the primary side channel of the first heat exchanger 101A can enter the secondary side channel of the third heat exchanger 103A via the first and second side controllable switches C21. If the outdoor temperature is too high, the cooling water temperature in the primary side pipe 103 is relatively high; therefore, the compression refrigeration cycle system operates in compression cycle mode. In this case, a portion of the coolant from the air-cooled module 102B can enter the primary side channel of the third heat exchanger 103A before entering the evaporator 102-4B, allowing the coolant from the liquid-cooled module 101B and the coolant from the air-cooled module 102B to exchange heat within the third heat exchanger 103A.

[0130] like Figure 6 As shown, when the coolant in the liquid-cooled module 101B is cooled by the coolant in the air-cooled module 102B, it can enter the liquid-cooled module 101B to effectively cool components of the electronic device with high heat dissipation. The coolant in the air-cooled module 102B, after absorbing heat, can return to the compressor 102-1B and participate in the compression cycle. Therefore, in this embodiment, the coolant in the air-cooled module 102B compensates for the cooling capacity of the coolant in the liquid-cooled module 101B, ensuring that the coolant in the liquid-cooled module 101B has sufficient cooling capacity to effectively cool components of the electronic device with high heat dissipation. Thus, this embodiment allows for the bypassing of a portion of the low-temperature coolant from the air-cooled module 102B to achieve auxiliary cooling of the liquid-cooled module 101B, while maintaining the independence of the air-cooled module 102B and the liquid-cooled module 101B.

[0131] In some alternative methods, such as Figure 6 As shown, the cooling system 100 in this embodiment further includes a third secondary-side controllable switch C23. The secondary-side channel outlet of the first heat exchanger 101A is connected to the inlet of the liquid-cooled module 101B through the third secondary-side controllable switch C23. When the cooling system 100 is operating in the second target cooling mode, the third secondary-side controllable switch C23 is turned on. That is, while the first secondary-side controllable switch C21 and the second secondary-side controllable switch C22 are turned on, the third secondary-side controllable switch C23 can also be turned on, so that part of the coolant flowing out of the first heat exchanger from the liquid-cooled module 101B directly enters the liquid-cooled module 101B, and the other part enters the third heat exchanger 103A for temperature compensation.

[0132] In practical applications, such as Figure 6As shown, the embodiment of the present application can adjust the opening degree of the first secondary side controllable switch C21 and the third secondary side controllable switch C23 according to the actual situation, so as to control the temperature compensation degree of the cooling liquid of the air-cooled module 102B to the cooling liquid of the liquid-cooled module 101B. For example, if the primary side channel inlet measured temperature and the first preset temperature of the primary side channel inlet of the first heat exchanger 101A are too different, or the primary side channel outlet measured temperature and the first preset temperature of the primary side channel outlet of the first heat exchanger 101A are too different, the opening degree of the first secondary side controllable switch C21 can be increased, and the opening degree of the third secondary side controllable switch C23 can be reduced.

[0133] The embodiment of the present application also provides a control system, Figure 7 The structural schematic block diagram of the control system of the embodiment of the present application is shown. As Figure 7 As shown, the control system of the embodiment of the present application can include a sensing module 701, a control module 702 and a cooling system 703, the control module 702 is respectively in communication connection with the controllable switch module M and the sensing module 701;

[0134] As Figure 7 As shown, the sensing module 701 is used for sending at least the primary side channel inlet measured temperature and the primary side channel outlet measured temperature of the first heat exchanger to the control module, and the control module 702 is used for executing the method of the embodiment of the present application based on the primary side channel inlet measured temperature and the primary side channel outlet measured temperature, so as to control the controllable switch module M to adjust the operation mode of the cooling system.

[0135] In some embodiments, the sensing module can include a first temperature sensor and a second temperature sensor, the first temperature sensor can collect the primary side channel inlet measured temperature, and the second temperature sensor can collect the primary side channel outlet measured temperature.

[0136] In some embodiments, the sensing module can further include a flow sensor, which can collect the primary side channel flow of the first heat exchanger, and the control module can comprehensively determine whether the operation mode of the cooling system needs to be changed through the controllable switch assembly based on the primary side channel flow, the primary side channel inlet measured temperature and the primary side channel outlet measured temperature of the first heat exchanger.

[0137] The embodiment of the present application also provides a control method of a cooling system, which can be executed by an electronic device or a chip in the electronic device. Figure 8 The flow chart of the control method of the cooling system of the embodiment of the present application is shown. As Figure 8 As shown, when the operation mode of the cooling system is the initial cooling mode, the control method of the cooling system of the embodiment of the present application can include:

[0138] Step 801: obtaining a primary side passage inlet measured temperature of the first heat exchanger and a primary side passage outlet measured temperature of the first heat exchanger.

[0139] Step 802: judging whether the primary side passage inlet measured temperature and the primary side passage outlet measured temperature satisfy the relaxation heat exchange constraint condition at the same time.

[0140] If the primary side passage inlet measured temperature and the primary side passage outlet measured temperature satisfy the relaxation heat exchange constraint condition at the same time, it indicates that the cooling liquid of the primary side pipeline can provide sufficient cold energy for the first heat exchanger, and thus step 803 can be performed. If the primary side passage inlet measured temperature and / or the primary side passage outlet measured temperature, it indicates that the cooling liquid of the primary side pipeline is difficult to provide sufficient cold energy for the first heat exchanger, and thus step 804 can be performed.

[0141] Step 803: maintaining the operation mode of the cooling system.

[0142] Step 804: based on the primary side passage inlet measured temperature and the primary side passage outlet measured temperature, controlling the controllable switch module to modify the operation mode of the cooling system from the initial cooling mode to the first target cooling mode.

[0143] In the case that the cooling liquid temperature of the primary side pipeline is the same, the heat exchange capacity of the first heat exchanger in the first target cooling mode is higher than the heat exchange capacity of the first heat exchanger in the initial cooling mode, and the power consumption of the air cooling module in the first target cooling mode is higher than the power consumption of the air cooling module in the initial cooling mode.

[0144] In an optional manner, Figure 9 A cooling system operation mode modification flowchart of an embodiment of the present application is shown. As shown in the figure, Figure 9 based on the primary side passage inlet measured temperature and the primary side passage outlet measured temperature, controlling the controllable switch module to modify the operation mode of the cooling system from the initial cooling mode to the first target cooling mode, can include:

[0145] Step 901: obtaining a primary side passage cooling liquid flow of the first heat exchanger, and the current flow of the primary side passage cooling liquid of the first heat exchanger is less than a preset maximum flow.

[0146] Step 902: increasing the primary side passage cooling liquid flow of the first heat exchanger, and updating the primary side passage inlet measured temperature and the primary side passage outlet measured temperature.

[0147] Step 903: If the primary side channel coolant flow rate of the first heat exchanger is equal to the preset maximum flow rate, and if the primary side channel inlet measured temperature and / or the primary side channel outlet measured temperature does not satisfy the relaxed heat exchange constraint condition, the control unit controls the controllable switch module to modify the operation mode of the cooling system from the initial cooling mode to the first target cooling mode.

[0148] Step 904: If the primary side channel coolant flow rate of the first heat exchanger is less than the preset maximum flow rate, and if the primary side channel inlet measured temperature and the primary side channel outlet measured temperature both satisfy the relaxed heat exchange constraint condition, the control unit maintains the operation mode of the cooling system.

[0149] In an optional manner, when the cooling system operates in the first target cooling mode, Figure 10 Another flowchart of modifying the operation mode of the cooling system is shown. As shown in the flowchart, Figure 10 The method of the embodiments of the present application can further include:

[0150] Step 1001: If the primary side channel inlet measured temperature and the primary side channel outlet measured temperature both satisfy the strict heat exchange constraint condition, the control unit controls the first controllable switch module to modify the operation mode of the cooling system from the first target cooling mode to the initial cooling mode based on the primary side channel inlet measured temperature and the primary side channel outlet measured temperature.

[0151] Step 1002: Reduce the primary side channel coolant flow rate of the first heat exchanger to a target coolant flow rate. The target coolant flow rate is less than the preset maximum flow rate.

[0152] Step 1003: If the primary side channel inlet measured temperature and / or the primary side channel outlet measured temperature does not satisfy the strict heat exchange constraint condition, the control unit maintains the first target cooling mode.

[0153] In actual applications, the control of the controllable switch module to modify the operation mode of the cooling system from the first target cooling mode to the initial cooling mode based on the primary side channel inlet measured temperature and the primary side channel outlet measured temperature can include:

[0154] When the duration that the primary side channel inlet measured temperature satisfies the strict heat exchange constraint condition is greater than or equal to a preset duration, and the duration that the primary side channel outlet measured temperature satisfies the strict heat exchange constraint condition is greater than or equal to the preset duration, the control unit controls the controllable switch module to modify the operation mode of the cooling system from the first target cooling mode to the initial cooling mode.

[0155] When the duration that the primary side channel inlet measured temperature does not satisfy the strict heat exchange constraint condition is less than the preset duration, and / or, the duration that the primary side channel outlet measured temperature does not satisfy the strict heat exchange constraint condition is less than the preset duration, the control unit maintains the first target cooling mode.

[0156] In an alternative, the cooling system of the embodiments of the present application comprises a third heat exchanger, when the first connection mode is the second series connection mode, the method of the embodiments of the present application can further comprise:

[0157] When the primary side channel inlet measured temperature and / or the primary side channel outlet measured temperature does not meet the maintenance condition of the operation mode, the first secondary side controllable switch and the second secondary side controllable switch are controlled to be turned on. Of course, the third secondary side controllable switch can also be controlled to be turned on.

[0158] In actual application, when the cooling system is started, the operation mode of the cooling system can be the second target cooling mode, so as to ensure that the first heat exchanger can provide sufficient cold energy for the liquid cooling module. When the cooling system works for a period of time, the operation mode of the cooling system can be directly switched to the first target series connection mode. In this operation mode, the cooling system not only can realize temperature decoupling, but also has lower energy consumption, and can better play the energy saving function of the liquid cooling module.

[0159] In one or more technical solutions provided in the embodiments of the present application, when the cooling system operates in the initial cooling mode, the primary side channel inlet measured temperature and the primary side channel outlet measured temperature simultaneously meet the relaxation heat exchange constraint condition, and the primary side channel of the first heat exchanger and the primary side channel of the second heat exchanger are arranged on the primary side pipeline through the controllable switch module in the first connection mode. In this case, the refrigerant temperature of the primary side pipeline is appropriate, which can provide sufficient cold energy for the first heat exchanger, so that the first heat exchanger can transfer the cold energy to the refrigerant of the liquid cooling module through heat exchange, so as to sufficiently cool the elements with high heat generation of the electronic device. Moreover, the liquid cooling module is used to cool the devices with high heat generation in the electronic device, and the air cooling module is used to cool the elements with low heat generation in the electronic device, so that the refrigerant of the primary side pipeline entering the second heat exchanger can meet the cold energy demand of the second heat exchanger for the refrigerant of the air cooling module, so that the cooling effect of the air cooling module on the elements with low heat generation of the electronic device is better.

[0160] When the cooling system is operating in the first target cooling mode, the measured temperatures at the inlet and / or outlet of the primary side channel do not meet the relaxed heat transfer constraint conditions. This indicates that the refrigerant temperature in the primary side pipeline is not low enough, resulting in insufficient heat transfer capacity of the first heat exchanger. Consequently, the liquid cooling module cannot adequately cool the components of the electronic equipment that generate a significant amount of heat. Considering that the heat transfer capacity of the first heat exchanger in the first target cooling mode is higher than that in the initial cooling mode when the refrigerant temperature in the primary side pipeline is the same, the operating mode of the cooling system can be adjusted from the initial cooling mode to the first target cooling mode. This allows the primary side channels of the first and second heat exchangers to be connected to the primary side pipeline via a controllable switch module in a second connection manner. This enhances the heat transfer capacity of the first heat exchanger, enabling it to provide sufficient cooling capacity to the refrigerant of the liquid cooling module and prioritizing the cooling of the components in the electronic equipment that generate a significant amount of heat. Meanwhile, considering the high temperature of the refrigerant in the primary side piping, the cooling capacity of the air-cooled module for components with low heat generation in electronic devices can be improved by increasing the power consumption of the air-cooled module.

[0161] As can be seen, the cooling system of this embodiment can determine whether it is necessary to adjust the connection method of the primary side channels of the first heat exchanger and the second heat exchanger on the primary side pipeline by means of the switch control module, based on whether the measured temperatures at the inlet and outlet of the primary side channel simultaneously meet the relaxed heat transfer constraint conditions. This adaptively controls the heat transfer capacity of the first heat exchanger and the energy consumption of the air-cooled module. This not only reduces the problem of insufficient energy-saving advantages of the liquid-cooled module due to excessively low coolant temperature without lowering the coolant temperature in the primary side pipeline, but also ensures the cooling effect of the liquid-cooled module and the air-cooled module on the electronic equipment. This achieves temperature decoupling between the liquid-cooled module and the air-cooled module, allowing them to fully exert their optimal cooling effect on the electronic equipment.

[0162] In some embodiments, only one set of secondary-side piping (including primary and secondary-side piping and secondary-side management) needs to be installed outside the cabinet to simultaneously address the heat dissipation requirements of both air cooling and liquid cooling, reducing the complexity of piping within the data center and lowering construction and maintenance costs. Simultaneously, by combining the air-cooled module with a compression refrigeration cycle system, the limitation on cooling water temperature is removed. The cooling water temperature can be set according to the requirements of the liquid-cooled module, maximizing the cooling water temperature and fully utilizing natural cold sources, thereby reducing the data center's annual cooling energy consumption.

[0163] The above describes the scheme provided by the embodiments of the present disclosure mainly from the perspective of the electronic device. It can be understood that the electronic device contains the hardware structure and / or software module corresponding to the execution of each function in order to implement the above functions. Those skilled in the art should easily realize that, in combination with the units and algorithm steps of the examples described in the embodiments disclosed herein, the present disclosure can be realized in the form of hardware or the combination of hardware and computer software. Whether a certain function is executed in the form of hardware or computer software driven hardware depends on the specific application and design constraints of the technical solution. The skilled person can use different methods to implement the described functions for each specific application, but such implementation should not be considered beyond the scope of the present disclosure.

[0164] The embodiments of the present disclosure can divide the functional units of the electronic device according to the above method examples. For example, each functional module can be divided corresponding to each function, or two or more functions can be integrated in one processing module.

As shown in Figure 11 The control device 1100 of the cooling system includes:

[0168] The switching module 1103 is configured to control the controllable switch module to modify the operation mode of the cooling system from the initial cooling mode to a first target cooling mode based on the primary side channel inlet measured temperature and the primary side channel outlet measured temperature if the primary side channel inlet measured temperature and / or the primary side channel outlet measured temperature does not simultaneously satisfy the relaxed heat exchange constraint condition.

[0169] In the case that the cooling liquid temperature of the primary side pipeline is the same, the heat exchange capacity of the first heat exchanger in the first target cooling mode is higher than the heat exchange capacity of the first heat exchanger in the initial cooling mode, and the power consumption of the air cooling module 112B in the first target cooling mode is higher than the power consumption of the air cooling module 112B in the initial cooling mode.

[0170] In a possible implementation, the acquisition module 1101 is further configured to acquire a primary side passage cooling liquid flow rate of the first heat exchanger, and the primary side passage cooling liquid flow rate of the first heat exchanger is less than a preset maximum flow rate.

[0172] In a possible implementation, the maintaining module 1102 is further configured to, if the primary side passage cooling liquid flow rate of the first heat exchanger is less than the preset maximum flow rate, and if the primary side passage inlet measured temperature and the primary side passage outlet measured temperature simultaneously satisfy the relaxed heat exchange constraint condition, maintain the operation mode of the cooling system.

[0173] In a possible implementation, when the cooling system operates in the first target cooling mode, the switching module 1103 is further configured to, if the primary side passage inlet measured temperature and the primary side passage outlet measured temperature simultaneously satisfy the strict heat exchange constraint condition, control the controllable switch module to modify the operation mode of the cooling system from the first target cooling mode to the initial cooling mode based on the primary side passage inlet measured temperature and the primary side passage outlet measured temperature, and reduce the cooling liquid flow rate of the primary side passage of the first heat exchanger to a target cooling liquid flow rate.

[0174] The maintaining module 1102 is further configured to, if the primary side passage inlet measured temperature and / or the primary side passage outlet measured temperature does not satisfy the strict heat exchange constraint condition, maintain the first target cooling mode.

[0175] In a possible implementation, the switching module 1103 is configured to control the controllable switch module to modify the operation mode of the cooling system from the first target cooling mode to the initial cooling mode when the time length during which the primary-side passage inlet measured temperature satisfies the strict heat exchange constraint condition is greater than or equal to a preset time length, and the time length during which the primary-side passage outlet measured temperature satisfies the strict heat exchange constraint condition is greater than or equal to a preset time length.

[0176] The maintaining module 1102 is further configured to maintain the first target cooling mode when the time length during which the primary-side passage inlet measured temperature does not satisfy the strict heat exchange constraint condition is less than a preset time length, and / or the time length during which the primary-side passage outlet measured temperature does not satisfy the strict heat exchange constraint condition is greater than or equal to a preset time length.

[0177] In a possible implementation, the cooling system is the cooling system described in the present application, and when the first connection mode is the second series connection mode, the switching module 1103 is further configured to control the first secondary-side controllable switch and the second secondary-side controllable switch to be turned on when the primary-side passage inlet measured temperature of the liquid cooling module and / or the primary-side passage outlet measured temperature of the liquid cooling module does not satisfy the maintaining condition of the operation mode.
