[0044] To facilitate understanding, a brief introduction and explanation of some terms or basic concepts of technology involved in the embodiments of this disclosure will be given first.

[0045] (a) Primary and secondary sides of the heat dissipation system

[0046] The primary side refers to the circulation loop in the heat dissipation system that transfers cold energy from a cold source to a cooling medium. The cold source may include a refrigeration unit, a cooling tower, and a dry cooler, where the cooling tower and dry cooler belong to a natural cooling system, and the refrigeration unit belongs to a mechanical refrigeration system. The secondary side refers to the circulation loop in the heat dissipation system that transfers cold energy from the primary side to the equipment or environment that needs to be cooled. The primary side cooling medium (the first cooling medium in this embodiment) is cooled by the cold source, and then the cold energy is transferred to the secondary side through a 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 this embodiment).

[0047] (II) Air-cooled cabinets and liquid-cooled cabinets

[0048] Air-cooled server racks primarily rely on airflow for heat dissipation, and the air-cooling device in this disclosure is used to cool air-cooled server racks. Liquid-cooled server racks use liquid as a heat dissipation medium, and the liquid-cooling device in this disclosure is used to cool liquid-cooled server racks.

[0049] The above is an introduction to some of the concepts involved in the embodiments of this disclosure, which will not be repeated below.

[0050] As described in the background section, with the development of computing power fields such as intelligent computing servers, the demand for heat dissipation in IT server racks with high heat generation is increasing, and combined air-liquid cooling is gradually becoming the mainstream choice for next-generation data center cooling systems. However, because data center planning and construction must be ahead of business forecasting and deployment, it is difficult to control the amount of liquid cooling and air cooling in the cooling system, resulting in an uncertain ratio of air cooling to liquid cooling. Furthermore, changes in computing power in the computing center can lead to significant power fluctuations in different servers, resulting in problems such as excessive power consumption in a single rack and localized high temperatures. Therefore, determining the cooling strategy of the cooling system to meet its heat dissipation requirements is an urgent problem to be solved.

[0051] In view of this, the current cooling capacity of the primary side of the heat dissipation system can be determined by the temperature difference and flow rate of the cooling medium at the inlet of the primary side of the heat dissipation system. Then, based on the current temperature and target temperature difference of the second cooling medium at the inlet and outlet of the liquid-cooled cabinet, the target total liquid cooling capacity required to meet the liquid cooling heat dissipation requirements can be determined. Furthermore, based on the cooling capacity of the primary side and the target total liquid cooling capacity, the target total air cooling capacity required to meet the air cooling heat dissipation requirements is obtained. Since the air-cooling device and the liquid-cooling device in this embodiment are connected to the same cold source, the ratio of the first target total flow rate and the second target total flow rate can be determined based on the target total liquid cooling capacity and the target total air cooling capacity. Thus, by using the ratio of the first target total flow rate and the second target total flow rate as a heat dissipation strategy, the heat dissipation requirements of both the air cooling and liquid cooling systems can be simultaneously met when the heat dissipation strategy is implemented.

[0052] The embodiments of this disclosure will now be described in detail with reference to the accompanying drawings.

[0053] The control method for the heat dissipation system provided in this disclosure can be applied to heat dissipation systems. Figure 1 is a schematic diagram of a heat dissipation system provided in an embodiment of this disclosure. As shown in Figure 1, the heat dissipation system 1 may include a cold source 10, a primary-side circulation loop 20, and a secondary-side circulation loop 30.

[0054] The cold source 10 is used to provide cooling capacity to the primary side circulation loop 20. The cold source 10 exchanges heat with the first cooling medium in the primary side circulation loop, thereby delivering cooling capacity to the primary side circulation loop 20.

[0055] For example, the cold source 10 can be a cooling tower, a dry cooler, or a refrigeration system, etc.

[0056] The primary circulation loop 20 is used to transfer the cooling capacity from the cold source 10 to the secondary circulation loop 30.

[0057] Figure 2 is a schematic diagram of another heat dissipation system provided in an embodiment of this disclosure. As shown in Figure 2, the primary side circulation loop 20 may include a liquid cooling device 201 and an air cooling device 202. In Figure 2, the solid lines in the primary side circulation loop 20 represent the primary side water inlet pipes, and the dashed lines in the primary side circulation loop 20 represent the primary side water outlet pipes.

[0058] 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, and is connected to the cold source 10.

[0059] Optionally, the liquid cooling device 201 is a liquid cooling dispensing unit (CDU). The liquid cooling CDU connects the primary circulation loop 20 and the secondary circulation loop 30, transferring 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 from the cold source to the equipment requiring cooling.

[0060] The air-cooling device 202 is used to output cold air to cool equipment or environments that require air-cooling heat dissipation. The air-cooling device 202 is connected to the cold source 10, and the air-cooling device 202 can be connected in parallel with the liquid cooling device 201.

[0061] In this embodiment, the air-cooled device (water-fluorine dual-coil in-row air conditioner) and the liquid-cooled device (liquid-cooled CDU) are connected in parallel and share an outdoor cold source, which can realize various equipment layout construction modes. The ratio of air-cooled heat dissipation to liquid-cooled heat dissipation can be infinitely adjusted from 0% to 100%.

[0062] Optionally, the air-cooled unit 202 can be a water-refrigerant dual-coil in-row air conditioner, a precision refrigeration system specifically designed for high-density racks. It is placed directly on the air-cooled rack, close to the heat source, for direct heat dissipation, suitable for data center environments with enclosed hot and cold aisles. A water-refrigerant dual-coil in-row air conditioning system typically consists of an outdoor unit, indoor terminal units (including dual-coil units), a water piping system, and a control system. The outdoor unit provides the cooling source, delivering chilled water to the indoor terminal units via the water piping system. The indoor terminal units then exchange heat through the dual coils, thereby eliminating the cooling / heating load on the room.

[0063] The secondary circulation loop 30 is used to transfer the cooling capacity from the primary circulation loop 20 to the equipment that needs to be cooled.

[0064] Continuing as shown in Figure 2, the secondary-side circulation loop 30 may include a liquid-cooled cabinet 301. In Figure 2, the solid lines in the secondary-side circulation loop 30 represent the secondary-side water inlet pipes, and the dashed lines represent the secondary-side water outlet pipes.

[0065] The liquid-cooled cabinet 301 uses liquid as the heat dissipation medium. The heat generated by the equipment inside the liquid-cooled cabinet 301 is transferred to the second cooling medium in the secondary side circulation loop 30 through heat sinks or heat pipes. The second cooling medium carries away the heat generated by the equipment inside the liquid-cooled cabinet 301. Liquid-cooled cabinets 301 typically include two types: cold plate liquid cooling and immersion liquid cooling.

[0066] Figure 3 is a schematic diagram of another heat dissipation system provided in an embodiment of this disclosure. As shown in Figure 3, the heat dissipation system 1 may further include an air-cooled cabinet 40. The air-cooled cabinet 40 mainly relies on airflow for heat dissipation. It is usually equipped with a fan or other airflow device, and the cool air generated by the air-cooling device 202 carries away the heat generated by the equipment inside the air-cooled cabinet 40 and discharges it into the external environment.

[0067] It is understood that the equipment requiring cooling in this embodiment of the present disclosure can be housed in the air-cooled cabinet 40 and the liquid-cooled cabinet 301.

[0068] 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.

[0069] in,

[0070] The first temperature sensor is used to detect the temperature value of the cold source 10.

[0071] The second temperature sensor is used to detect the temperature of the first cooling medium at the inlet of the liquid cooling device 201.

[0072] The third temperature sensor is used to detect the temperature of the first cooling medium at the outlet of the liquid cooling device 201.

[0073] The fourth temperature sensor is used to detect the temperature of the second cooling medium at the inlet of the liquid-cooled cabinet 301.

[0074] The fifth temperature sensor is used to detect the temperature of the second cooling medium at the outlet of the liquid cooling cabinet 301.

[0075] The sixth temperature sensor is used to detect the temperature value of the first cooling medium at the inlet of the primary side circulation loop 20. Here, the inlet of the primary side circulation loop refers to the position where the first cooling medium leaves the cold source 10 in the primary side circulation loop 20.

[0076] The seventh temperature sensor is used to detect the temperature value of the first cooling medium at the outlet of the primary side circulation loop 20. Here, the outlet of the primary side circulation loop refers to the position where the first cooling medium in the primary side circulation loop 20 begins to approach the cold source 10.

[0077] The first flow sensor is used to detect the flow rate of the first cooling medium at the inlet of the liquid cooling device 201.

[0078] The second flow sensor is used to detect the flow rate of the first cooling medium at the outlet of the liquid cooling device 201.

[0079] The third flow sensor is used to detect the flow rate of the first cooling medium at the inlet of the air-cooled device 202.

[0080] The fourth flow sensor is used to detect the flow rate of the first cooling medium at the outlet of the air-cooled device 202.

[0081] The fifth flow sensor is used to detect the flow rate of the first cooling medium at the inlet of the primary side circulation loop 20.

[0082] The sixth flow sensor is used to detect the flow rate of the first cooling medium at the outlet of the primary side circulation loop 20.

[0083] The seventh flow sensor is used to detect the flow rate at the inlet of the second cooling unit 301 in the liquid cooling cabinet.

[0084] The eighth flow sensor is used to detect the flow rate at the outlet of the second cooling unit at the liquid cooling cabinet 301.

[0085] The first valve is used to control the flow rate of the first cooling medium flowing through the liquid cooling device 201.

[0086] The second valve is used to control the flow rate of the first cooling medium flowing through the air-cooled device 202.

[0087] The third valve is used to control the flow rate of the second cooling medium flowing through the liquid cooling cabinet 301.

[0088] It is understood that the number of cold source 10, liquid cooling device 201, air cooling device 202, and liquid cooling cabinet 301 in this embodiment can be multiple. When the number of cold source 10, liquid cooling device 201, air cooling device 202, and liquid cooling cabinet 301 is multiple, the number of temperature sensors, flow sensors, and valves installed at the inlet and outlet of the cold source 10, liquid cooling device 201, air cooling device 202, and liquid cooling cabinet 301 is also multiple. For example, the number of temperature sensors and flow sensors installed at the inlet and outlet of the cold source 10, liquid cooling device 201, air cooling device 202, and liquid cooling cabinet 301 is twice that of the corresponding cold source 10, liquid cooling device 201, air cooling device 202, and liquid cooling cabinet 301, and the number of valves installed at the inlet of the liquid cooling device 201, air cooling device 202, and liquid cooling cabinet 301 can be the same as the number of the corresponding liquid cooling device 201, air cooling device 202, and liquid cooling cabinet 301.

[0089] In some embodiments, the heat dissipation system 1 may further include a controller.

[0090] 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 rate of the first cooling medium at the inlet and outlet of the primary side of the heat dissipation system; to determine the target total liquid 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-cooled cabinet, the liquid cooling device being used to cool the liquid-cooled cabinet; to determine the 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, the air cooling device and the liquid cooling device being connected to the same cold source; to determine a heat dissipation strategy based on the target total liquid cooling capacity and the target total air cooling capacity, the heat dissipation strategy including the ratio of the first target total flow rate of the first cooling medium flowing through the liquid cooling device to the second target total flow rate of the first cooling medium flowing through the air cooling device; and to operate according to the heat dissipation strategy.

[0091] The controller can also be used to determine the target liquid cooling capacity of each of the multiple liquid cooling devices based on the target total liquid cooling capacity and the number of liquid cooling devices; determine each first target flow rate value based on the target liquid cooling capacity; and determine each second target flow rate value based on the target total air cooling capacity and the number of air cooling devices.

[0092] The controller can also be used to acquire the temperature value of the cold source connected to the air-cooling device; and determine the operating mode of the air-cooling device based on the temperature value of the cold source.

[0093] The controller can also be used to determine the operating mode of the air-cooled device as natural water cooling circulation mode when the temperature of the cold source is less than or equal to the first preset temperature value; to determine the operating mode of the air-cooled device as the first compressor circulation mode when the temperature of the cold source is greater than the second preset temperature value; and to determine the operating mode of the air-cooled device as the second compressor circulation mode and cooling water circulation mode when the temperature 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.

[0094] The controller can also be used to acquire the temperature difference and flow rate of the second cooling medium at the inlet and outlet of each liquid cooling unit in multiple liquid cooling cabinets; control the opening of valves connected to the liquid cooling cabinets so that the flow rate through the liquid cooling cabinets meets the target flow rate corresponding to the liquid cooling cabinets; one liquid cooling cabinet corresponds to one valve, and the target flow rate corresponding to the liquid cooling cabinet is determined by the temperature value at the outlet of each liquid cooling cabinet.

[0095] The controller can also be used to determine the target total air cooling capacity of the air-cooled device in the heat dissipation system based on the difference between the cooling capacity of the primary side of the heat dissipation system and the target total liquid cooling capacity.

[0096] The controller can also be used to obtain the pressure difference between the inlet and outlet of the liquid cooling cabinet; if 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, it will output a prompt message to indicate that there is a leak.

[0097] The controller can be electrically connected to the cold source 10, the liquid cooling device 201, the air cooling device 202, and various temperature sensors, flow sensors, and valves. A controller is a device that can generate operation control signals based on instruction opcodes and timing signals to instruct the heat dissipation system 1 to execute control commands. For example, the controller can be a central processing unit (CPU), a network processor (NP), a digital signal processor (DSP), a microprocessor, a microcontroller, a programmable logic device (PLD), or any combination thereof. The controller can also be other devices with processing functions, such as circuits, devices, or software modules; this disclosure does not impose any limitations on these aspects.

[0098] In some embodiments, the controller can be a microcontroller unit (MCU). An MCU, also known as a single-chip microcomputer, is a chip-level computer that integrates a central processing unit (CPU) with appropriately reduced frequency and specifications, along with peripheral interfaces such as memory, timer, USB, A / D converter, UART, PLC, DMA, and even LCD driver circuitry, all onto a single chip. This allows for different combinations of control for various applications.

[0099] In addition, the controller can be used to control the operation of each component in the heat dissipation system 1 so that each component of the heat dissipation system 1 can operate to achieve each predetermined function of the heat dissipation system 1.

[0100] As mentioned above, with the development of computing power fields such as intelligent computing servers, the demand for heat dissipation in IT server racks with high heat generation is increasing, and combined air-liquid cooling is gradually becoming the mainstream choice for next-generation data center cooling systems. However, because data center planning and construction must be ahead of business forecasting and deployment, it is difficult to control the ratio of liquid cooling to air cooling in the cooling system. Therefore, how to determine the cooling strategy of the cooling system to meet its heat dissipation requirements is an urgent problem to be solved.

[0101] Based on this, embodiments of this disclosure provide a control method for a heat dissipation system. The cooling capacity of the primary side of the heat dissipation system can be determined by the temperature difference and flow rate of the cooling medium at the inlet of the primary side. Then, based on the current temperature and target temperature difference of the second cooling medium at the inlet and outlet of the liquid-cooled cabinet, the target total liquid cooling capacity required to meet the liquid cooling demand can be determined. Furthermore, based on the cooling capacity of the primary side and the target total liquid cooling capacity, the target total air cooling capacity required to meet the air cooling demand is obtained. Since the air-cooling device and the liquid-cooling device in this embodiment are connected to the same cold source, the ratio of the first target total flow rate and the second target total flow rate can be determined based on the target total liquid cooling capacity and the target total air cooling capacity. Thus, by using the ratio of the first target total flow rate and the second target total flow rate as a heat dissipation strategy, the air cooling and liquid cooling demands of the heat dissipation system can be simultaneously met when the heat dissipation strategy is implemented.

[0102] The following describes a control method for a heat dissipation system provided by an embodiment of the present disclosure, with reference to the accompanying drawings.

[0103] Figure 4 is a schematic flowchart of a heat dissipation system control method provided in an embodiment of this disclosure. As shown in Figure 4, the heat dissipation system control method provided in this disclosure includes the following steps S1-S5.

[0104] S1. Determine the cooling capacity of the primary side of the heat dissipation system based on the temperature difference and flow rate of the first cooling medium at the inlet and outlet of the primary side of the heat dissipation system.

[0105] Optionally, the cooling capacity of the primary side of the heat dissipation system can be determined using the following formula: Q=C*M*ΔT

[0106] Where 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 rate 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.

[0107] S2. Based on the current temperature difference and target temperature difference of the second cooling medium at the inlet and outlet of the liquid-cooled cabinet, determine the target total liquid cooling capacity of the liquid cooling device in the heat dissipation system.

[0108] The liquid cooling unit is used to cool the liquid-cooled cabinet. The target total liquid cooling capacity is the sum of the cooling capacity of all liquid cooling units required to make the temperature difference between the second cooling medium at the inlet and outlet of the liquid-cooled cabinet reach the target temperature difference.

[0109] As one possible approach, the target total liquid cooling capacity of the liquid cooling device in the heat dissipation system is determined based on the difference between the target temperature difference and the current temperature difference.

[0110] S3. Based on the cooling capacity of the primary side of the heat dissipation system and the target total liquid cooling capacity, determine the target total air cooling capacity of the air-cooled device in the heat dissipation system.

[0111] The air-cooled device and the liquid-cooled device are connected to the same cold source.

[0112] As one possible approach, the target total air cooling capacity of the air-cooled device in the heat dissipation system is determined based on the difference between the cooling capacity of the primary side of the heat dissipation system and the target total liquid cooling capacity.

[0113] It should be noted that when the equipment requiring cooling is a liquid-cooled cabinet, the target total liquid cooling capacity can be 90% of the cooling load required for heat dissipation by the liquid-cooled cabinet, and the target air-cooling capacity can be 10% of the cooling load required for heat dissipation by the liquid-cooled cabinet. When the equipment requiring cooling is a combination of air-cooled and liquid-cooled cabinets, the target liquid cooling capacity can be 10%-90% of the cooling load required for heat dissipation, and the target air-cooling capacity can be 10%-100% of the cooling load required for heat dissipation by the liquid-cooled cabinet. In other words, when the equipment requiring cooling is a combination of air-cooled and liquid-cooled cabinets, the proportion of liquid cooling and air cooling can be any value from 0% to 100%, thus satisfying various liquid cooling and air cooling ratio strategies.

[0114] S4. Determine the heat dissipation strategy based on the target total liquid cooling capacity and the target total air cooling capacity.

[0115] The heat dissipation strategy includes the ratio of a first target total flow rate of the first cooling medium flowing through the liquid cooling device to a second target total flow rate of the first cooling medium flowing through the air cooling device. It can be understood that the ratio of the first target total flow rate to the second target total flow rate can be achieved by adjusting the valve openings of the cold source flowing into the liquid cooling device and the cold source flowing into the air cooling device. The magnitude of the first target total flow rate can affect the liquid cooling heat dissipation of the heat dissipation system, and the second target total flow rate can affect the air cooling heat dissipation of the heat dissipation system.

[0116] Optionally, when there are multiple liquid cooling devices and air cooling devices, the heat dissipation strategy may also include a target flow rate value for each liquid cooling device and a target flow rate value for each air cooling device.

[0117] S5. Operate according to the heat dissipation strategy.

[0118] The embodiment shown in Figure 4 offers at least the following advantages: In this embodiment, the cooling capacity of the primary side of the heat dissipation system can be determined by the temperature difference and flow rate of the cooling medium at the inlet of the primary side. Then, based on the current temperature and target temperature difference of the second cooling medium at the inlet and outlet of the liquid-cooled cabinet, the target total liquid cooling capacity required to meet the liquid cooling demand can be determined. Furthermore, based on the cooling capacity of the primary side and the target total liquid cooling capacity, the target total air cooling capacity required to meet the air cooling demand can be obtained. Since the air-cooling device and the liquid-cooling device in this embodiment are connected to the same cold source, the ratio of the first target total flow rate and the second target total flow rate can be determined based on the target total liquid cooling capacity and the target total air cooling capacity. Thus, by using the ratio of the first target total flow rate and the second target total flow rate as a heat dissipation strategy, the air cooling and liquid cooling demands of the heat dissipation system can be simultaneously met while the heat dissipation strategy is running.

[0119] In some embodiments, step S4 above can be specifically implemented as the following steps S41-S43:

[0120] S41. Based on the target total liquid cooling capacity and the number of liquid cooling devices, determine the target liquid cooling capacity of each liquid cooling device among the multiple liquid cooling devices.

[0121] As one possible implementation, the target liquid cooling capacity of each liquid cooling unit can be determined by the ratio between the target total liquid cooling capacity and the number of liquid cooling units.

[0122] As another possible implementation, the target liquid cooling capacity of the liquid cooling device can be determined by the temperature difference between 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.

[0123] S42. Determine the first target flow rate value based on the target liquid cooling capacity.

[0124] Optionally, the first target flow rate value can 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 inlet and outlet of the first cooling medium in the liquid cooling device.

[0125] S43. Determine the flow rate value for each second target based on the target total air-cooled cooling capacity and the number of air-cooled devices.

[0126] As one possible implementation, the target air-cooling capacity of each air-cooled unit can be determined by the ratio between the target total air-cooling capacity and the number of air-cooled units.

[0127] As can be seen from the above embodiments, 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 can be obtained when the target total liquid cooling capacity / target total air cooling capacity is met.

[0128] In some embodiments, the control method for the heat dissipation system provided in this disclosure may further include: acquiring the temperature value of a cold source connected to the air-cooling device; and determining the operating mode of the air-cooling device based on the temperature value of the cold source.

[0129] As can be seen from the above embodiments, the present disclosure embodiments adaptively adjust the working mode of the air-cooled device according to the water supply temperature of the cold source, which can meet the cooling load requirements while avoiding unnecessary energy waste.

[0130] As one possible implementation, when the temperature of the cold source is less than or equal to the first preset temperature value, the working mode of the air-cooled device is determined to be the natural water cooling circulation mode.

[0131] The first preset temperature value can be set by the designer at the factory or by the user during use. For example, the first preset temperature value can be 20 degrees Celsius. Natural water cooling circulation mode means that the compressor stops running, and the cooling capacity provided solely by the natural cooling coils is used to cool the equipment requiring air cooling in air-cooled or liquid-cooled cabinets. In this way, when the cold source temperature is low, the cooling capacity provided by the cold source can meet the air cooling requirements of the air-cooled unit.

[0132] As another possible implementation, when the temperature of the cold source is greater than the second preset temperature value, the working mode of the air-cooled device is determined to be the first compressor cycle mode.

[0133] The second preset temperature value can be set by the designer at the factory or by the user during use. For example, the second preset temperature value can be 35 degrees Celsius. The compressor cycle mode refers to the compressor starting the refrigeration cycle mode and adjusting the compressor's operating frequency according to the air outlet temperature setpoint of the air-cooled unit.

[0134] Because when the temperature of the cold source is high, a compressor is needed to provide sufficient cooling capacity to meet the cooling and heating requirements of the air-cooled device.

[0135] As another possible implementation, when the temperature 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-cooled device is determined to be the second compressor circulation mode and the cooling water circulation mode.

[0136] In the first compressor cycle mode, the compressor operating frequency is greater than that in the second compressor cycle mode.

[0137] In this way, a portion of the cooling capacity can be obtained from the cold source for air-cooled device heat dissipation, and another portion can be obtained from the compressor refrigeration for air-cooled device heat dissipation, thereby improving the heat dissipation efficiency of air-cooled device.

[0138] In some embodiments, the control method for the heat dissipation system provided in this disclosure may further include: acquiring the temperature difference and flow rate of the second cooling medium at the inlet and outlet of each liquid cooling device in a plurality of liquid cooling cabinets; controlling the opening degree of the valve connected to the liquid cooling cabinet so that the flow rate through the liquid cooling cabinet meets the target flow rate corresponding to the liquid cooling cabinet; one liquid cooling cabinet corresponds to one valve, and the target flow rate corresponding to the liquid cooling cabinet is determined by the temperature value at the outlet of each liquid cooling cabinet.

[0139] As can be seen from the above embodiments, by adjusting the valve opening corresponding to the liquid cooling cabinet, the flow rate through each liquid cooling cabinet can be controlled, thereby ensuring that the flow rate through the liquid cooling cabinet meets the target flow rate value corresponding to the liquid cooling cabinet.

[0140] Figure 5 is a flowchart illustrating another control method for a heat dissipation system provided in this disclosure, the method comprising the following steps:

[0141] Determine the target temperature difference between the inlet and outlet of the second cooling medium in the liquid-cooled cabinet.

[0142] Adjust the opening degree of the valve corresponding to each liquid cooling cabinet.

[0143] By adjusting the opening of the valves corresponding to each liquid-cooled cabinet, the flow rate of the secondary cooling medium in each cabinet is controlled, ensuring that the temperature at the outlet of each cabinet remains within a preset temperature range. For example, the preset temperature range could be 7-10 degrees Celsius. This allows the overall power of the secondary side of the cooling system to be maintained at a relatively stable level, reducing power fluctuations on the secondary side.

[0144] The cooling load of each liquid cooling cabinet is determined based on the temperature difference and flow rate of the second cooling medium at the inlet and outlet of each liquid cooling cabinet.

[0145] The sum of the cooling loads of all liquid-cooled cabinets is taken as the total cooling load of the heat dissipation system.

[0146] 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 through each liquid-cooled CDU.

[0147] Adjust the operating frequency of the liquid-cooled CDU circulation pump so that the flow rate of the second cooling medium through each liquid-cooled CDU meets the target flow rate.

[0148] In this way, by detecting the temperature, pressure and flow on the liquid cooling cabinet branch through 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 temperature regulation of the second cooling medium can be reduced, thereby improving the response speed and control accuracy of the heat dissipation system.

[0149] In some embodiments, the control method of the heat dissipation system provided in this disclosure may further include acquiring the pressure difference between the inlet and outlet of the liquid-cooled cabinet; and outputting a prompt message indicating that there is a leak 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.

[0150] The target differential pressure refers to a relatively stable pressure difference between the inlet and outlet of the liquid-cooled cabinet under normal conditions. This differential pressure is typically determined based on factors such as the design of the liquid-cooled cabinet, the flow rate of the secondary cooling medium, and the cooling efficiency. The target differential pressure can be set by the designer at the factory or by the user during operation.

[0151] Optionally, the target differential pressure can be the average of the inlet and outlet differential pressures of all liquid-cooled cabinets.

[0152] For example, the prompt message could be "Please check for leaks!".

[0153] As can be seen from the above embodiments, when the pressure difference between the inlet and outlet of the liquid-cooled cabinet is greater than the target pressure difference, and the difference between the pressure difference between the inlet and outlet of the liquid-cooled cabinet and the target pressure difference is greater than the average of the inlet and outlet pressure differences of all liquid-cooled cabinets, it indicates that the pressure difference of the liquid-cooled cabinet is abnormally high, and there may be a leakage. Outputting a warning message indicating a possible leakage can promptly remind the user to confirm and repair the leakage.

[0154] Figure 6 is a flowchart illustrating another control method for a heat dissipation system provided in this disclosure, the method comprising the following steps:

[0155] Obtain the pressure values ​​at the inlet and outlet of each liquid-cooled cabinet.

[0156] After obtaining the pressure values ​​at the inlet and outlet of each liquid-cooled cabinet, the pressure difference between the inlet and outlet of each liquid-cooled cabinet is determined.

[0157] Determine the average pressure difference at the inlet and outlet of all liquid-cooled cabinets.

[0158] Determine whether the difference between the pressure difference at the inlet and outlet of each liquid-cooled cabinet and the average pressure difference is greater than a preset value.

[0159] If so, output a message indicating a leak.

[0160] If not, output a message indicating that the liquid cooling cabinet is functioning normally.

[0161] Figure 7 is a flowchart illustrating another control method for a heat dissipation system provided in this disclosure. The control method for the heat dissipation system in this disclosure will be described in detail below with reference to Figure 7. As shown in Figure 7, the method includes the following steps:

[0162] The temperature difference between the inlet and outlet of the second cooling medium at each liquid-cooled CDU is detected, and the cooling load on the secondary side of each liquid-cooled CDU is determined based on the temperature difference.

[0163] The sum of the cooling loads on the secondary side of all liquid-cooled CDUs is taken as the total liquid cooling load of the heat dissipation system.

[0164] Obtain the temperature difference between the inlet and outlet of the first cooling medium in the primary side pipeline, and determine the total cooling capacity of the primary side based on the temperature difference.

[0165] 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.

[0166] The operating mode of the air-cooled device is determined based on the inlet water temperature T on the primary side. If T ≤ 20℃ (℃ is the temperature unit in degrees Celsius), the operating mode is natural water cooling circulation mode; if 20℃ < T ≤ 35℃, the operating mode is natural water cooling circulation mode and compressor circulation mode; if T > 35℃, the operating mode is compressor circulation mode.

[0167] The algorithm optimizes and controls the primary water supply temperature and volume to minimize the system's energy consumption.
