[0048] To facilitate understanding, the basic concepts of some terms or technologies involved in the embodiments of the present application are first briefly introduced and explained.

[0049] (I) Primary and secondary sides of the cooling system

[0050] The primary side refers to the circulation loop in the heat dissipation system that transfers cold from the cold source to the cooling medium. The cold source may include a refrigeration unit, a cooling tower, and a dry cooler, wherein the cooling tower and the dry cooler belong to the natural cooling system, and the refrigeration unit belongs to the mechanical refrigeration system. The secondary side refers to the circulation loop in the heat dissipation system that transfers cold from the primary side to the equipment or environment that needs to be cooled. The primary side cooling medium (the first cooling medium in the embodiment of the present application) is cooled by the cold source, and then the cold is transferred to the secondary side through the heat exchange device, and then transferred to the equipment or environment that needs to be cooled by the secondary side cooling medium (the second cooling medium in the embodiment of the present application).

[0051] (2) Air-cooled cabinets and liquid-cooled cabinets

[0052] Air-cooled cabinets mainly rely on air flow to dissipate heat, and the air-cooling device in this application is used to cool the air-cooled cabinet. Liquid-cooled cabinets use liquid as a heat dissipation medium, and the liquid-cooling device in this application is used to cool the liquid-cooled cabinet.

[0053] The above is an introduction to some concepts involved in the embodiments of the present application, which will not be repeated below.

[0054] As described in the background technology, at present, with the development of computing power fields such as intelligent computing servers, the demand for heat dissipation of high-heat-generating IT cabinets is also increasing, and air-liquid collaborative heat dissipation has gradually become the mainstream choice for the new generation of data center cooling systems. However, since the planning and construction of data centers must be ahead of the estimation and deployment of business, it is difficult to control the liquid cooling and air cooling in the cooling system, resulting in an uncertain ratio of air cooling and liquid cooling. In addition, changes in the computing power of the computing center will cause large power variations in different servers, and there will be problems such as excessive power consumption of a single cabinet and local high temperature. Therefore, how to determine the cooling strategy of the cooling system to meet the cooling needs of the cooling system is an urgent problem to be solved.

[0055] In view of this, the embodiment of the present application can determine the cooling capacity of the primary side of the current heat dissipation system through the temperature difference and flow value of the cooling medium at the inlet of the primary side of the heat dissipation system. Then, according to the current temperature value and the target temperature difference of the second cooling medium at the inlet and outlet of the liquid cooling cabinet, the target total liquid cooling cooling capacity required to meet the liquid cooling heat dissipation demand can be determined, and then the target total air cooling cooling capacity that meets the air cooling heat dissipation demand is obtained according to the cooling capacity of the primary side and the target total liquid cooling cooling capacity. Since the cold source connected to the air cooling device and the liquid cooling device in the embodiment of the present application is the same, the ratio of the first target total flow value and the second target total flow value can be determined according to the target total liquid cooling cooling capacity and the target total air cooling cooling capacity. In this way, the ratio of the first target total flow value and the second target total flow value is used as a heat dissipation strategy, and the air cooling heat dissipation demand and the liquid cooling heat dissipation demand of the heat dissipation system can be met at the same time when the heat dissipation strategy is run.

[0056] The following is a detailed introduction to the embodiments of the present application in conjunction with the accompanying drawings.

[0057] The control method of the heat dissipation system provided in the embodiment of the present application can be applicable to the heat dissipation system. Figure 1 This is a schematic diagram of the structure of a heat dissipation system provided in an embodiment of the present application. Figure 1 As shown, the heat dissipation system 1 may include a cold source 10, a primary circulation loop 20 and a secondary circulation loop 30.

[0058] The cold source 10 is used to provide cold energy for the primary circulation loop 20 . The cold source 10 exchanges heat with the first cooling medium in the primary circulation loop, thereby delivering cold energy to the primary circulation loop 20 .

[0059] Exemplarily, the cold source 10 may be cooling equipment such as a cooling tower, a dry cooler or a refrigeration system.

[0060] The primary circulation loop 20 is used to transfer the cold energy from the cold source 10 to the secondary circulation loop 30 .

[0061] Figure 2 This is a schematic diagram of the structure of another heat dissipation system provided in an embodiment of the present application. Figure 2 As shown, the primary circulation loop 20 may include a liquid cooling device 201 and an air cooling device 202 . Figure 2 The solid line in the primary circulation loop 20 is the primary water inlet pipeline, and the dotted line in the primary circulation loop 20 is the primary water outlet pipeline.

[0062] The liquid cooling device 201 is used to realize heat exchange between the primary side circulation loop 20 and the secondary side circulation loop 30 . The liquid cooling device 201 is connected to the primary side circulation loop 20 and the secondary side circulation loop 30 . The liquid cooling device 201 is in communication with the cold source 10 .

[0063] Optionally, the liquid cooling device 201 is a liquid cooling dispensing unit (CDU), which is a device connecting the primary circulation loop 20 and the secondary circulation loop 30, and transfers the cooling capacity of the first cooling medium in the primary circulation loop 20 to the second cooling medium in the secondary circulation loop 30 through heat exchange. The liquid cooling CDU can indirectly transfer the cooling capacity in the cold source to the equipment that needs to be cooled.

[0064] The air cooling device 202 is used to output cold air to cool down the equipment or environment that needs air cooling. The air cooling device 202 is connected to the cold source 10, and the air cooling device 202 can be arranged in parallel with the liquid cooling device 201.

[0065] In the embodiment of the present application, the air cooling device (water-fluorine double-coil row air conditioner) and the liquid cooling device (liquid-cooled CDU) are arranged in parallel and share an outdoor cold source, which can realize a variety of equipment layout construction modes, and the ratio of air cooling and liquid cooling can be infinitely adjusted from 0% to 100%.

[0066] Optionally, the air-cooling device 202 can be a water-fluorine double-coil row air conditioner, which is a precision refrigeration system specially designed for high-density racks. It is placed directly on the air-cooled cabinet, close to the heat source, to achieve direct heat dissipation, and is suitable for data center environments with closed hot and cold channels. The water-fluorine double-coil row air conditioning system usually consists of an outdoor host, an indoor terminal device (including a double-coil unit), a water pipe system, and a control system. The outdoor host provides a cold source, and the cold water is transported to the indoor terminal device through the water pipe system, and the indoor terminal device performs heat exchange through the double coil, thereby eliminating the cold / heat load of the room.

[0067] The secondary circulation loop 30 is used to transfer the cooling energy from the primary circulation loop 20 to the equipment that needs cooling.

[0068] Continue as Figure 2 As shown, the secondary circulation loop 30 may include a liquid cooling cabinet 301 . Figure 2 The solid line in the secondary circulation loop 30 is the secondary water inlet pipeline, and the dotted line in the secondary circulation loop 30 is the secondary water outlet pipeline.

[0069] The liquid cooling cabinet 301 uses liquid as a heat dissipation medium. The heat generated by the equipment in the liquid cooling cabinet 301 is transferred to the second cooling medium in the secondary circulation loop 30 through the heat sink or heat pipe. The second cooling medium takes away the heat generated by the equipment in the liquid cooling cabinet 301. The liquid cooling cabinet 301 generally includes two types: cold plate liquid cooling and immersion liquid cooling.

[0070] Figure 3This is a schematic diagram of the structure of another heat dissipation system provided in an embodiment of the present application. Figure 3 As shown, the heat dissipation system 1 may also include an air-cooled cabinet 40. The air-cooled cabinet 40 mainly relies on air flow to dissipate heat. It is usually equipped with a fan or other air flow device, and the cold air generated by the air-cooling device 202 takes away the heat generated by the equipment in the air-cooled cabinet 40 and discharges it to the external environment.

[0071] It can be understood that the equipment that needs to be cooled in the embodiment of the present application can be set in the air-cooled cabinet 40 and the liquid-cooled cabinet 301.

[0072] In some embodiments, the heat dissipation system 1 may further include a first temperature sensor, a second temperature sensor, a third temperature sensor, a fourth temperature sensor, a fifth temperature sensor, a sixth temperature sensor, a seventh temperature sensor, a first valve, a second valve and a third valve.

[0073] The first temperature sensor is used to detect the temperature value of the cold source 10 .

[0074] The second temperature sensor is used to detect the temperature value of the first cooling medium at the inlet of the liquid cooling device 201.

[0075] The third temperature sensor is used to detect the temperature value of the first cooling medium at the outlet of the liquid cooling device 201 .

[0076] The fourth temperature sensor is used to detect the temperature value of the second cooling medium at the inlet of the liquid cooling cabinet 301 .

[0077] The fifth temperature sensor is used to detect the temperature value of the second cooling medium at the outlet of the liquid cooling cabinet 301 .

[0078] The sixth temperature sensor is used to detect the temperature value of the first cooling medium at the inlet of the primary circulation loop 20 , where the inlet of the primary circulation loop refers to the position in the primary circulation loop 20 where the first cooling medium leaves the cold source 10 .

[0079] The seventh temperature sensor is used to detect the temperature value of the first cooling medium at the outlet of the primary circulation loop 20 , where the outlet of the primary circulation loop refers to the position in the primary circulation loop 20 where the first cooling medium begins to approach the cold source 10 .

[0080] The first flow sensor is used to detect the flow value of the first cooling medium at the inlet of the liquid cooling device 201.

[0081] The second flow sensor is used to detect the flow value of the first cooling medium at the outlet of the liquid cooling device 201.

[0082] The third flow sensor is used to detect the flow value of the first cooling medium at the inlet of the air cooling device 202.

[0083] The fourth flow sensor is used to detect the flow value of the first cooling medium at the outlet of the air cooling device 202.

[0084] The fifth flow sensor is used to detect the flow value of the first cooling medium at the inlet of the primary side circulation loop 20.

[0085] The sixth flow sensor is used to detect the flow value of the first cooling medium at the outlet of the primary side circulation loop 20.

[0086] The seventh flow sensor is used to detect the flow value of the second cooling unit at the inlet of the liquid cooling cabinet 301.

[0087] The eighth flow sensor is used to detect the flow value of the second cooling unit at the outlet of the liquid cooling cabinet 301.

[0088] The first valve is used to control the flow rate of the first cooling medium flowing through the liquid cooling device 201 .

[0089] The second valve is used to control the flow rate of the first cooling medium flowing through the air cooling device 202 .

[0090] The third valve is used to control the flow rate of the second cooling medium flowing through the liquid cooling cabinet 301 .

[0091] It can be understood that the number of the cold source 10, the liquid cooling device 201, the air cooling device 202, and the liquid cooling cabinet 301 in the embodiment of the present application can be multiple. When the number of the cold source 10, the liquid cooling device 201, the air cooling device 202, and the liquid cooling cabinet 301 is multiple, the number of temperature sensors, flow sensors, and valves set at the inlet and outlet of the cold source 10, the liquid cooling device 201, the air cooling device 202, and the liquid cooling cabinet 301 is also multiple. For example, the number of temperature sensors and flow sensors set at the inlet and outlet of the cold source 10, the liquid cooling device 201, the air cooling device 202, and the liquid cooling cabinet 301 is twice that of the corresponding cold source 10, the liquid cooling device 201, the air cooling device 202, and the liquid cooling cabinet 301, and the number of valves set at the inlet of the liquid cooling device 201, the air cooling device 202, and the liquid cooling cabinet 301 can be the same as the number of the corresponding liquid cooling device 201, the air cooling device 202, and the liquid cooling cabinet 301.

[0092] In some embodiments, the heat dissipation system 1 may further include a controller.

[0093] The controller is used to determine the cooling capacity of the primary side of the heat dissipation system based on the temperature difference and flow value of the first cooling medium at the inlet and outlet of the primary side of the heat dissipation system; determine the target total liquid-cooling cooling capacity of the liquid cooling device in the heat dissipation system based on the current temperature difference and target temperature difference of the second cooling medium at the inlet and outlet of the liquid-cooling cabinet, and the liquid cooling device is used to cool the liquid-cooling cabinet; determine the target total air-cooling cooling capacity of the air-cooling device in the heat dissipation system based on the cooling capacity of the primary side of the heat dissipation system and the target total liquid-cooling cooling capacity, and the air-cooling device and the liquid-cooling device are connected to the same cold source; determine the heat dissipation strategy based on the target total liquid-cooling cooling capacity and the target total air-cooling cooling capacity, and the heat dissipation strategy includes the ratio of a first target total flow value of the first cooling medium flowing through the liquid cooling device and a second target total flow value of the first cooling medium flowing through the air cooling device; and operate according to the heat dissipation strategy.

[0094] The controller can also be used to determine the target liquid cooling capacity of each liquid cooling device in multiple liquid cooling devices based on the target total liquid cooling capacity and the number of liquid cooling devices; determine each first target flow value according to the target liquid cooling capacity; and determine each second target flow value based on the target total air cooling capacity and the number of air cooling devices.

[0095] The controller can also be used to obtain the temperature value of a cold source connected to the air cooling device; and determine the operation mode of the air cooling device according to the temperature value of the cold source.

[0096] The controller can also be used to determine that the working mode of the air cooling device is a natural water cooling circulation mode when the temperature value of the cold source is less than or equal to a first preset temperature value; determine that the working mode of the air cooling device is a first compressor circulation mode when the temperature value of the cold source is greater than a second preset temperature value; and determine that the working mode of the air cooling device is a second compressor circulation mode and a cooling water circulation mode when the temperature value of the cold source is greater than the first preset temperature value and less than or equal to the second preset temperature value; wherein the compressor operating frequency in the first compressor circulation mode is greater than the compressor operating frequency in the second compressor circulation mode.

[0097] The controller can also be used to obtain the temperature difference and flow value of the second cooling medium at the inlet and outlet of each liquid cooling device in multiple liquid cooling cabinets; control the opening of the valve connected to the liquid cooling cabinet so that the flow value flowing through the liquid cooling cabinet meets the target flow value corresponding to the liquid cooling cabinet; one liquid cooling cabinet corresponds to one valve, and the target flow value corresponding to the liquid cooling cabinet is determined by the temperature value at the outlet of each liquid cooling cabinet.

[0103] A control method for a heat dissipation system provided in an embodiment of the present application is described below in conjunction with the accompanying drawings.

[0104] Figure 4 A schematic diagram of a control method for a heat dissipation system provided in an embodiment of the present application. Figure 4 As shown, the control method of the heat dissipation system provided in the present application includes the following steps S1-S5.

[0105] S1. Determine the cooling capacity of the primary side of the heat dissipation system based on the temperature difference and flow value of the first cooling medium at the inlet and outlet of the primary side of the heat dissipation system.

[0106] Optionally, the cooling capacity of the primary side of the heat dissipation system is determined by the following formula:

[0107] Q=C*M*ΔT

[0108] Among them, Q is the cooling capacity of the primary side of the heat dissipation system, C is the specific heat capacity of the first cooling medium, M is the flow value at the inlet and outlet of the primary side of the heat dissipation system, and ΔT is the temperature difference between the inlet and outlet of the primary side of the heat dissipation system.

[0109] S2. Determine a target total liquid cooling capacity of the liquid cooling device in the heat dissipation system based on a current temperature difference of the second cooling medium at an inlet and an outlet of the liquid cooling cabinet and a target temperature difference.

[0110] Among them, the liquid cooling device is used to cool the liquid cooling cabinet, and the target total liquid cooling refrigeration capacity is the sum of the refrigeration capacities of all liquid cooling devices required to make the temperature difference of the second cooling medium at the inlet and outlet of the liquid cooling cabinet reach the target temperature difference.

[0111] As a possible implementation manner, a target total liquid cooling capacity of a liquid cooling device in the heat dissipation system is determined according to a difference between a target temperature difference and a current temperature difference.

[0112] S3. Determine a target total air-cooling capacity of the air-cooling device in the heat dissipation system based on the cooling capacity of the primary side of the heat dissipation system and the target total liquid-cooling capacity.

[0113] The air cooling device and the liquid cooling device are connected to the same cold source.

[0114] As a possible implementation manner, based on the difference between the cooling capacity of the primary side of the heat dissipation system and the target total liquid cooling capacity, the target total air cooling capacity of the air cooling device in the heat dissipation system is determined.

[0115] It should be noted that when the equipment to be cooled is a liquid-cooled cabinet, the target total liquid-cooling cooling capacity can be 90% of the cooling load required for heat dissipation of the liquid-cooled cabinet, and the target air-cooling cooling capacity can be 10% of the cooling load required for heat dissipation of the liquid-cooled cabinet. When the equipment to be cooled is an air-cooled cabinet and a liquid-cooled cabinet, the target liquid-cooling cooling capacity can be 10%-90% of the cooling load required for heat dissipation, and the target air-cooling cooling capacity can be 10%-100% of the cooling load required for heat dissipation of the liquid-cooled cabinet. That is, when the equipment to be cooled is an air-cooled cabinet and a liquid-cooled cabinet, the liquid-cooling heat dissipation ratio and the air-cooling heat dissipation ratio can be any value from 0 to 100%, thereby satisfying various liquid-cooling heat dissipation and air-cooling heat dissipation ratio strategies.

[0116] S4. Determine a heat dissipation strategy based on the target total liquid cooling capacity and the target total air cooling capacity.

[0117] The heat dissipation strategy includes a ratio of a first target total flow value of the first cooling medium flowing through the liquid cooling device and a second target total flow value of the first cooling medium flowing through the air cooling device. It is understandable that the ratio of the first target total flow value and the second target total flow value can be achieved by adjusting the valve opening of the cold source flowing into the liquid cooling device and the valve opening of the cold source flowing into the air cooling device. The size of the first target total flow value can affect the liquid cooling heat dissipation of the heat dissipation system, and the second target total flow value can affect the air cooling heat dissipation of the heat dissipation system.

[0118] Optionally, when there are multiple liquid cooling devices and multiple air cooling devices, the heat dissipation strategy may further include a target flow value flowing through each liquid cooling device and a target flow value flowing through each air cooling device.

[0119] S5. Run according to the heat dissipation strategy.

[0120] Figure 4 The embodiment shown at least brings the following beneficial effects: the embodiment of the present application can determine the cooling capacity of the primary side of the current heat dissipation system through the temperature difference and flow value of the cooling medium at the inlet of the primary side of the heat dissipation system. Then, according to the current temperature value and the target temperature difference of the second cooling medium at the inlet and outlet of the liquid cooling cabinet, the target total liquid cooling cooling capacity required to meet the liquid cooling heat dissipation demand can be determined, and then the target total air cooling cooling capacity that meets the air cooling heat dissipation demand is obtained according to the cooling capacity of the primary side and the target total liquid cooling cooling capacity. Since the cold source connected to the air cooling device and the liquid cooling device in the embodiment of the present application is the same, the ratio of the first target total flow value and the second target total flow value can be determined according to the target total liquid cooling cooling capacity and the target total air cooling cooling capacity. In this way, the ratio of the first target total flow value and the second target total flow value is used as a heat dissipation strategy, and the air cooling heat dissipation demand and the liquid cooling heat dissipation demand of the heat dissipation system can be met at the same time when the heat dissipation strategy is run.

[0121] In some embodiments, the above step S4 can be specifically implemented as the following steps S41-S43:

[0122] S41. Determine a target liquid cooling capacity of each liquid cooling device in a plurality of liquid cooling devices based on a target total liquid cooling capacity and the number of liquid cooling devices.

[0123] As a possible implementation manner, the target liquid cooling capacity of each liquid cooling device may be determined by a ratio between the target total liquid cooling capacity and the number of liquid cooling devices.

[0124] As another possible implementation, the target liquid cooling capacity of the liquid cooling device may be determined by the temperature difference of the first cooling medium at the inlet and outlet of the liquid cooling device, the target total liquid cooling capacity and the number of liquid cooling devices.

[0125] S42. Determine each first target flow value according to the target liquid cooling capacity.

[0126] Optionally, the first target flow value may be obtained by dividing the target liquid cooling capacity by the specific heat capacity of the first cooling medium, and then by the temperature difference between the first cooling medium at the inlet and the outlet of the liquid cooling device.

[0127] S43. Determine each second target flow value based on the target total air-cooling refrigeration capacity and the number of air-cooling devices.

[0128] As a possible implementation manner, the target air-cooling refrigeration capacity of each air-cooling device may be determined by the ratio between the target total air-cooling refrigeration capacity and the number of air-cooling devices.

[0129] It can be seen from the above embodiments that based on the target total liquid cooling capacity / target total air cooling capacity and the number of liquid cooling devices / air cooling devices, the cooling capacity of each liquid cooling device / air cooling device when the target total liquid cooling capacity / target total air cooling capacity is met can be obtained.

[0130] In some embodiments, the control method of the heat dissipation system provided in the embodiments of the present application may further include: obtaining the temperature value of a cold source connected to the air cooling device; and determining the operation mode of the air cooling device according to the temperature value of the cold source.

[0131] It can be seen from the above embodiments that the embodiments of the present application adaptively adjust the working mode of the air cooling device according to the water supply temperature value of the cold source, which can avoid unnecessary energy waste while meeting the cooling load demand.

[0132] As a possible implementation manner, when the temperature value of the cold source is less than or equal to the first preset temperature value, the working mode of the air cooling device is determined to be a natural water cooling circulation mode.

[0133] The first preset temperature value may be set by the designer at the factory or by the user during use. For example, the first preset temperature value may be 20 degrees Celsius. The natural water cooling circulation mode means that the compressor stops running and only relies on the cooling capacity provided by the natural cooling coil to cool down the equipment in the air-cooled cabinet or liquid-cooled cabinet that requires air cooling. In this way, when the temperature of the cold source is low, the cooling capacity provided by the cold source can meet the air cooling demand of the air-cooled device.

[0134] As another possible implementation manner, when the temperature value of the cold source is greater than the second preset temperature value, the operating mode of the air cooling device is determined to be the first compressor circulation mode.

[0135] The second preset temperature value may be set by the designer at the factory or by the user during use. For example, the second preset temperature value may be 35 degrees Celsius. The compressor cycle mode refers to the compressor starting the refrigeration cycle mode and adjusting the operating frequency of the compressor according to the outlet temperature setting value of the air cooling device.

[0136] Because when the temperature of the cold source is high, a compressor is required to provide refrigeration sufficient to meet the air-cooling but thermal requirements of the air-cooling device.

[0137] As another possible implementation, when the temperature value of the cold source is greater than the first preset temperature value and less than or equal to the second preset temperature value, the working mode of the air cooling device is determined to be the second compressor circulation mode and the cooling water circulation mode.

[0138] The operating frequency of the compressor in the first compressor cycle mode is greater than the operating frequency of the compressor in the second compressor cycle mode.

[0139] In this way, a part of the cold energy used for air cooling and heat dissipation of the air cooling device can be obtained from the cold source, and another part of the cold energy used for air cooling and heat dissipation of the air cooling device can be obtained from the compressor refrigeration, thereby improving the heat dissipation efficiency of the air cooling device.

[0140] In some embodiments, the control method of the heat dissipation system provided in the embodiments of the present application may also include: obtaining the temperature difference and flow value of the second cooling medium at the inlet and outlet of each liquid cooling device in multiple liquid cooling cabinets; controlling the opening of the valve connected to the liquid cooling cabinet so that the flow value flowing through the liquid cooling cabinet meets the target flow value corresponding to the liquid cooling cabinet; one liquid cooling cabinet corresponds to one valve, and the target flow value corresponding to the liquid cooling cabinet is determined by the temperature value at the outlet of each liquid cooling cabinet.

[0141] It can be seen from the above embodiments that by adjusting the valve opening corresponding to the liquid cooling cabinet, the flow through each liquid cooling cabinet can be controlled, so that the flow value through the liquid cooling cabinet meets the target flow value corresponding to the liquid cooling cabinet.

[0142] Figure 5 A flow chart of another method for controlling a heat dissipation system provided in an embodiment of the present application, the method comprising the following steps:

[0143] A target temperature difference of the second cooling medium at an inlet and an outlet of the liquid cooling cabinet is determined.

[0144] Adjust the opening of the valve corresponding to each liquid cooling cabinet.

[0145] By adjusting the opening of the valve corresponding to each liquid cooling cabinet, the flow rate of the second cooling medium flowing through each liquid cooling cabinet is controlled so that the temperature value at the outlet of each liquid cooling cabinet is within a preset temperature range. For example, the preset temperature range may be 7-10 degrees Celsius. In this way, the overall power of the secondary side of the heat dissipation system can be maintained at a relatively stable level, reducing power fluctuations on the secondary side.

[0146] The cooling load of each liquid cooling cabinet is determined according to the temperature difference and flow rate of the second cooling medium at the inlet and outlet of each liquid cooling cabinet.

[0147] The sum of the cooling loads of all liquid-cooled cabinets is taken as the total cooling load of the cooling system.

[0148] The total cooling load of the heat dissipation system is divided by the number of liquid-cooled CDUs that are turned on to obtain the target flow rate of the second cooling medium flowing through each liquid-cooled CDU.

[0149] The operating frequency of the liquid-cooled CDU circulation pump is adjusted so that the flow rate of the second cooling medium flowing through each liquid-cooled CDU meets the target flow rate.

[0150] In this way, based on the detection of temperature, pressure and flow on the liquid cooling cabinet branch by the temperature sensor, pressure sensor and flow sensor corresponding to each liquid cooling cabinet, the temperature change of the second cooling medium in each liquid cooling cabinet branch can be monitored in real time. By adjusting the valve opening corresponding to the liquid cooling cabinet, the granularity of the temperature regulation of the second cooling medium can be reduced, thereby improving the response speed and control accuracy of the heat dissipation system.

[0151] In some embodiments, the control method of the heat dissipation system provided in the embodiments of the present application may also include obtaining the pressure difference between the inlet and the outlet of the liquid cooling cabinet; when the pressure difference is greater than the target pressure difference, and the difference between the pressure difference and the target pressure difference is greater than a preset value, outputting a prompt message for indicating the presence of a liquid leakage.

[0152] The target pressure difference is a relatively stable pressure difference between the inlet and outlet of the liquid cooling cabinet under normal circumstances. This pressure difference is usually determined based on factors such as the design of the liquid cooling cabinet, the flow rate of the second cooling medium, and the cooling efficiency. The target pressure difference can be set by the designer at the factory or by the user during use.

[0153] Optionally, the target pressure difference may be an average value of the inlet and outlet pressure differences of all liquid cooling cabinets.

[0154] Exemplarily, the prompt message may be “Please check for leakage!”.

[0155] It can be seen from the above embodiments that when the pressure difference between the inlet and outlet of the liquid cooling cabinet is greater than the target pressure difference, and the difference between the pressure difference between the inlet and outlet of the liquid cooling cabinet and the target pressure difference is greater than the average value of the inlet and outlet pressure differences of all liquid cooling cabinets, it indicates that the pressure difference of the liquid cooling cabinet is highly abnormal and there may be leakage. Outputting a prompt message for indicating the presence of leakage in the case of possible leakage can promptly remind the user to confirm and repair the leakage.

[0156] Figure 6 A flow chart of another method for controlling a heat dissipation system provided in an embodiment of the present application, the method comprising the following steps:

[0157] Obtain the pressure values ​​at the inlet and outlet of each liquid cooling cabinet.

[0158] After obtaining the pressure values ​​at the inlet and outlet of each liquid cooling cabinet, the pressure difference at the inlet and outlet of each liquid cooling cabinet is determined.

[0159] Determine the average of the pressure differences at the inlet and outlet of all liquid-cooled cabinets.

[0160] It is determined whether the difference between the pressure difference at the inlet and outlet of each liquid cooling cabinet and the average value of the pressure difference is greater than a preset value.

[0161] If so, output a prompt message to indicate that there is a leakage.

[0162] If not, a prompt message is output to indicate that the liquid cooling cabinet is normal.

[0163] Figure 7 A flow chart of another method for controlling a heat dissipation system provided in an embodiment of the present application is shown below. Figure 7 The control method of the heat dissipation system in this application is described in detail. Figure 7 The method shown comprises the following steps:

[0164] The temperature difference of the second cooling medium at the inlet and outlet of each liquid-cooled CDU is detected, and the cooling load of each liquid-cooled CDU on the secondary side is determined according to the temperature difference.

[0165] The sum of the cooling loads of all liquid-cooled CDUs on the secondary side is taken as the total liquid cooling load of the cooling system.

[0166] The temperature difference between the inlet and outlet of the first cooling medium at the primary side pipeline is obtained, and the total cooling capacity of the primary side is determined according to the temperature difference.

[0167] The total air cooling load of the heat dissipation system is determined as the difference between the total cooling capacity of the primary side and the total liquid cooling load of the heat dissipation system.

[0168] The working mode of the air cooling device is determined according to the inlet water temperature T on the primary side. If T≤20℃ (℃ is the temperature unit in degrees Celsius), the working mode is the natural water cooling circulation mode; if 20℃<T≤35℃, the working mode is the natural water cooling circulation mode and the compressor circulation mode; if T>35℃, the working mode is the compressor circulation mode.

[0169] The algorithm optimizes and controls the primary side water supply temperature and water supply volume to minimize the system's energy consumption.
