[0022] It should be noted that the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0023] As data centers continue to expand and data processing volumes surge, heat dissipation issues are becoming increasingly prominent. Liquid cooling systems, as a highly efficient heat dissipation technology, are becoming a primary method for temperature control in data centers. Liquid cooling systems use circulating pumps to power the coolant through circulation pipes, ensuring continuous flow and dissipating heat generated by data center equipment, thereby maintaining stable data center operations.

[0024] Existing liquid cooling systems require a refill unit consisting of a refill pump and piping to ensure the system's refill requirements. Furthermore, due to the volume changes of the coolant as the temperature fluctuates, the system also requires a pressure stabilization unit consisting of an expansion tank and its connecting piping components to maintain system pressure stability. However, if the coolant in the refill unit and pressure stabilization unit is not circulated for an extended period, it is prone to deterioration, requiring manual shutdown for maintenance to meet the system's operational requirements, impacting the system's normal operation.

[0025] Based on this, an embodiment of the present invention provides a control method, a control device and a medium for a liquid cooling system, which can accurately adjust the circulation and supply of the coolant when the liquid cooling system is online, thereby not only improving the cleanliness of the coolant, but also ensuring the continuous and stable operation of the liquid cooling system.

[0026] The embodiments of the present invention are further described below with reference to the accompanying drawings.

[0027] Reference Figure 1 , Figure 1 FIG. 1 is a schematic diagram of the structure of a liquid cooling system provided by an embodiment of the present invention. Figure 1In the example of FIG, the liquid cooling system includes a primary side module 100, a secondary side module 200, a heat exchange module 300 connected between the primary side module 100 and the secondary side module 200, and a control module 400, wherein the secondary side module 200 includes a secondary side pipeline 210, a liquid replenishing unit, a pressure stabilizing unit, a regulating unit and a cooling circulation unit, a first temperature sensor 260, a second temperature sensor 270, a first pressure sensor 280, a second pressure sensor 290, a third pressure sensor 2100 and a safety valve 2120, and the cooling circulation The ring unit includes a first circulation pump 251, a second circulation pump 252, a first on-off valve 253, a second on-off valve 254, a third on-off valve 255, and a fourth on-off valve 256. The first on-off valve 253 and the second on-off valve 254 are respectively disposed at both ends of the first circulation pump 251, and the third on-off valve 255 and the fourth on-off valve 256 are respectively disposed at both ends of the second circulation pump 252. The first circulation pump 251 and the second circulation pump 252 provide circulation power for the coolant, ensuring continuous flow of the coolant between the secondary side pipeline 210 and other components. It should be noted that the first on-off valve 253, the second on-off valve 254, the third on-off valve 255, and the fourth on-off valve 256 are all electrically controlled valves and are respectively connected to the control module 400.

[0028] Furthermore, the fluid replenishment unit, the pressure stabilization unit, the adjustment unit, the second temperature sensor 270 and the second pressure sensor 290 are arranged at the fluid inlet of the secondary side pipeline 210, the fluid replenishment unit 220 includes a fluid storage tank 221 and a fluid replenishment pump 222 arranged at the fluid replenishment port of the secondary side pipeline 210, the pressure stabilization unit includes an expansion tank 231, and the adjustment unit includes a solenoid valve 241. Specifically, the fluid storage tank 221 is used to store spare coolant. When the liquid cooling system needs to replenish coolant, the fluid replenishment pump 222 draws the coolant from the fluid storage tank 221 and injects it into the secondary side pipeline 210. Expansion tank 231 is connected to the output of refill pump 222 and is also connected to solenoid valve 241, the inputs of second on / off valve 254, and the inputs of fourth on / off valve 256, respectively. This allows the volume expansion of the coolant due to rising temperature to flow into expansion tank 231. When the coolant contracts due to falling temperature, the coolant in expansion tank 231 can flow back into secondary pipeline 210. Solenoid valve 241 is also connected to control module 400 to control the flow between expansion tank 231 and secondary pipeline 210. The coordinated operation of refill pump 222 and solenoid valve 241 ensures sufficient coolant flow and stable pressure within the liquid cooling system, thereby ensuring the proper operation of the liquid cooling system.

[0029] Furthermore, third pressure sensor 2100 is connected to the output of first on-off valve 253 and the output of third on-off valve 255, respectively. It is then connected through heat exchange module 300 to safety valve 2120, first temperature sensor 260, and first pressure sensor 280, located at the outlet of secondary pipeline 210. Safety valve 2120 automatically opens when the pressure in the liquid cooling system exceeds a safety threshold, releasing excess pressure and ensuring safe operation of the liquid cooling system. First temperature sensor 260, second temperature sensor 270, first pressure sensor 280, and second pressure sensor 290 are each connected to control module 400 and are used to monitor the state parameters of the coolant in secondary pipeline 210 in real time, ensuring that the coolant in secondary pipeline 210 operates within appropriate operating conditions. The coolant temperature and pressure data are then fed back to control module 400.

[0030] Furthermore, the primary module 100 includes a primary pipeline 110, an electric two-way valve 120, a third temperature sensor 130, a fourth temperature sensor 140, a fourth pressure sensor 150, and a fifth pressure sensor 160. The electric two-way valve 120, the third temperature sensor 130, and the fourth pressure sensor 150 are disposed at the liquid inlet of the primary pipeline 110 and are connected to the fourth temperature sensor 140 and the fifth pressure sensor 160 disposed at the liquid outlet of the primary pipeline 110 through the heat exchange module 300. Specifically, the electric two-way valve 120 adjusts the flow of coolant according to system requirements. The third temperature sensor 130, the fourth temperature sensor 140, the fourth pressure sensor 150, and the fifth pressure sensor 160 are respectively connected to the control module 400 to monitor the state parameters of the coolant in the primary pipeline 110 in real time, ensure that the coolant in the primary pipeline 110 operates under appropriate operating conditions, and provide feedback of the coolant temperature and pressure data to the control module 400.

[0031] It should be noted that the heat exchange module 300 of the embodiment of the present invention includes a plate heat exchanger 310. By using the plate heat exchanger 310, heat is transferred between the coolant in the primary side pipeline 110 and the coolant in the secondary side pipeline 210, ensuring that the coolant can effectively absorb and dissipate heat, thereby maintaining the stable operation of the liquid cooling system.

[0032] The liquid cooling system described in the embodiment of the present invention is intended to more clearly illustrate the technical solution of the embodiment of the present invention, and does not constitute a limitation on the technical solution provided by the embodiment of the present invention. Those skilled in the art will know that with the evolution of the liquid cooling system and the emergence of new application scenarios, the technical solution provided in the embodiment of the present invention is also applicable to similar technical problems.

[0033] It will be understood by those skilled in the art that Figure 1The structure of the liquid cooling system shown in the figure does not constitute a limitation on the embodiments of the present invention, and may include more or fewer components than shown in the figure, or combine certain components, or arrange the components differently.

[0034] Based on the structure of the above-mentioned liquid cooling system, various embodiments of a control method for the liquid cooling system according to an embodiment of the present invention are proposed.

[0035] Reference Figure 2 As shown, Figure 2 This is a flow chart of a control method for a liquid cooling system provided by an embodiment of the present invention. The control method for a liquid cooling system can be applied to Figure 1 The liquid cooling system shown in the figure can refer to the above Figure 1 The liquid cooling system includes a secondary side pipeline, a solenoid valve provided in the secondary side pipeline, a liquid replenishing pump, and a plurality of circulation pumps. The method includes but is not limited to steps S100 to S300: Step S100: Acquire a first operating gear of at least one circulation pump, an operating state of a solenoid valve, and a second operating gear of a fluid infusion pump.

[0036] Step S200: determining dynamic active water parameters according to the first operating gear of the circulation pump.

[0037] Step S300: Control the operating state of the solenoid valve and the second operating gear of the fluid infusion pump according to the dynamic active water parameters.

[0038] In steps S100 to S300 of some embodiments, the circulating pump is used to drive the circulation of the coolant in the liquid cooling circuit, and the refill pump is used to replenish the coolant into the liquid cooling system to ensure that there is sufficient coolant in the liquid cooling system and to maintain the normal operating pressure and flow of the liquid cooling system. First, the first operating gear corresponding to the circulating pump and the second operating gear corresponding to the refill pump are obtained, that is, the first operating gear is the real-time operating gear of the circulating pump, and the second operating gear is the real-time operating gear of the refill pump. In one embodiment, while obtaining the real-time operating gears of the circulating pump and the refill pump, the operating time of the circulating pump and the refill pump can be obtained, that is, the first operating time corresponding to the circulating pump and the second operating time corresponding to the refill pump are obtained.

[0039] Furthermore, the solenoid valve's operating state includes open or closed. The control module sends commands to adjust the solenoid valve's opening or closing to control the flow of coolant in the expansion tank. It is understood that the motor speed of the circulation pump and the make-up pump is adjusted by changing the output frequency of the inverter. Therefore, different gears can be set, each corresponding to a specific frequency, to achieve graded control of the circulation pump and make-up pump motor speeds to regulate the coolant flow in the liquid cooling circuit. For example, starting with a minimum output frequency of 25Hz, gear 1 can be set, gear 2 corresponds to an output frequency of 30Hz, and gear 3 corresponds to an output frequency of 35Hz. Each gear interval has an output frequency of 5Hz, up to the highest gear 6 corresponding to a maximum output frequency of 50Hz. It should be noted that in low gear, the circulation pump operates at a lower speed, suitable for light loads or low cooling capacity requirements; in high gear, the circulation pump operates at a higher speed, providing a greater flow rate to meet high cooling capacity requirements. Additionally, during the operation of the liquid cooling system, if insufficient coolant is detected, the refill pump is controlled to increase its gear position to increase the refill flow rate; otherwise, the gear position is controlled to decrease the refill flow rate. Furthermore, the dynamic live water parameter can be determined based on factors such as the first operating gear of the circulating pump and system requirements. This parameter can be used to assess the coolant flow state and the operation of the liquid cooling system in real time. The operating state of the solenoid valve and the second operating gear of the refill pump can then be dynamically adjusted based on the dynamic live water parameter to meet the system's coolant demand and improve the cleanliness of the coolant.

[0040] It is understandable that the control method of the liquid cooling system in the embodiment of the present invention obtains the first operating gear of at least one circulation pump, the operating state of the solenoid valve, and the second operating gear of the refill pump, and then determines the dynamic live water parameter based on the first operating gear of the circulation pump, and finally controls the operating state of the solenoid valve and the second operating gear of the refill pump based on the dynamic live water parameter. By real-time monitoring the operating gears of the circulation pump and the refill pump on the secondary side pipeline and the operating state of the solenoid valve, the embodiment of the present invention can accurately adjust the circulation and replenishment of the coolant in the pipeline when the liquid cooling system is online, which not only improves the cleanliness of the coolant, but also ensures the continuous and stable operation of the liquid cooling system.

[0041] In some embodiments, reference Figure 3 As shown, the above embodiment of step S200 of determining the dynamic active water parameters according to the first operating gear of the circulating pump includes but is not limited to the following steps S210 to S220: Step S210: obtaining a preset dynamic water activity coefficient.

[0042] Step S220 , calculating and obtaining a dynamic active water parameter according to a preset dynamic active water coefficient, the first operating gear of the circulation pump, and a preset time interval.

[0043] It is understandable that in the embodiments of steps S210 to S220, the dynamic active water parameters can be calculated using the obtained preset dynamic active water coefficient, the first operating gear of the circulating pump and the preset time interval. Specifically, the operating gear of the circulating pump of the liquid cooling system can be adjusted in real time according to the change in pressure, or the operating gear of the circulating pump can also be adjusted in real time according to the temperature of the coolant in the liquid cooling system. In addition, the operating gear of the circulating pump can also be adjusted according to the preset operating mode of the liquid cooling system (such as energy-saving mode, high-efficiency heat dissipation mode, etc.) or according to a preset time program. Furthermore, the preset time interval is the time period for calculating the dynamic active water parameters, and then the first operating gear of the circulating pump is obtained in real time within each preset time interval and the dynamic active water parameters are calculated according to the preset dynamic active water coefficient.

[0044] It should be noted that the specific values ​​of the preset dynamic water activity coefficient and the preset time interval can be selected and adjusted by those skilled in the art. Specifically, the value range of the preset dynamic water activity coefficient in the embodiment of the present invention can be between 3 and 12, and the preset time interval can be set to 1 minute, 2 minutes, or 3 minutes, etc. Specifically, the dynamic water activity parameters can be calculated as follows: Y=k×A1 Among them, Y is the dynamic active water parameter, k is the preset dynamic active water coefficient, and A1 is the first operating gear of the circulation pump.

[0045] In some embodiments, the liquid cooling system in the embodiment of the present invention further includes a pressure sensor disposed between the solenoid valve and the liquid replenishing pump, such as Figure 1 As shown, the pressure sensor can be a second pressure sensor arranged at the liquid inlet of the secondary side pipeline, which is used to detect the pressure of the liquid inlet end of the secondary side pipeline in real time, that is, the pressure of the secondary side pipeline where the expansion tank and the fluid infusion pump are located.

[0046] In some embodiments, reference Figure 4 As shown, the step S300 of the above embodiment controls the operating state of the solenoid valve and the second operating gear of the infusion pump according to the dynamic live water parameter, including but not limited to the following steps S310 to S320: Step S310: When the dynamic active water parameter is less than or equal to the dynamic active water threshold, a first pressure value detected in real time by the first pressure sensor is obtained.

[0047] Step S320: When the first pressure value is less than the first preset pressure value, the infusion pump is started, the second operating gear of the infusion pump is adjusted to the first preset operating gear, and the solenoid valve is controlled to remain in an open state within a first preset time period.

[0048] It is understood that in the embodiment of steps S310 to S320, by comparing the dynamic live water parameter determined in step S200 of the above embodiment with the dynamic live water threshold, when the dynamic live water parameter is less than or equal to the dynamic live water threshold, that is, when the dynamic live water parameter is lower than the preset dynamic live water threshold, the first pressure value detected in real time by the first pressure sensor is obtained. Furthermore, the first pressure value can be compared with the first preset pressure value. When the first pressure value is less than the first preset pressure value, it indicates that the coolant flow activity of the liquid cooling system is insufficient and the pressure at the liquid inlet end of the secondary side pipeline is low. The control fluid replenishment pump is started, and its second operating gear is adjusted to the first preset operating gear, and the solenoid valve is controlled to remain open within the first preset time period. Under the joint action of the fluid replenishment pump and the solenoid valve, the pressure of the liquid cooling system is balanced, and coolant is replenished to the liquid cooling system, so that the coolant in the expansion tank and the storage tank is cooled and circulated, which helps to improve the coolant flow activity. It should be noted that the specific values ​​of the dynamic active water threshold, the first preset pressure value, the first preset operating gear and the first preset time period can be selected and adjusted by those skilled in the art. Specifically, the value range of the dynamic active water threshold in the embodiment of the present invention can be between 2000 and 9000, the value range of the first preset pressure value can be between 0.9 bar and 1.2 bar, the first preset time period can be set between 4 seconds and 6 seconds, and the range of the first preset operating gear can be set between gear 1 and gear 2. The motor output frequency corresponding to the specific gear can refer to the relevant contents of the above-mentioned steps S100 to step S300 embodiments.

[0049] In some embodiments, the above-mentioned embodiment step S300 of controlling the operating state of the solenoid valve and the second operating gear of the infusion pump according to the dynamic living water parameter also includes the following steps: when the dynamic living water parameter is greater than the dynamic living water threshold, obtaining the first operating gear of at least one circulation pump, the operating state of the solenoid valve and the second operating gear of the infusion pump again.

[0050] It should be noted that by comparing the dynamic living water parameter determined in step S200 of the above embodiment with the dynamic living water threshold, when the dynamic living water parameter is greater than the dynamic living water threshold, that is, the dynamic living water parameter exceeds the preset dynamic living water threshold, return to step S100 of the above embodiment, and obtain the first operating gear of at least one circulation pump, the operating status of the solenoid valve and the second operating gear of the infusion pump again. It is necessary to readjust the dynamic living water parameter and control the solenoid valve and the infusion pump, that is, repeat steps S100 to S300 of the above embodiment, and the embodiments of the present invention will not be repeated here.

[0051] In some embodiments, reference Figure 4 As shown, the control method of the liquid cooling system according to the embodiment of the present invention further includes but is not limited to the following steps S330: Step S330: When the first pressure value is greater than or equal to the first preset pressure value, the solenoid valve is controlled to remain in an open state within a second preset time period.

[0052] It should be noted that, in the embodiment of step S330, by comparing the first pressure value with the first preset pressure value, when the first pressure value is greater than or equal to the first preset pressure value, that is, the pressure at the liquid inlet end of the secondary side pipeline is too high, the solenoid valve is controlled to remain in an open state within the second preset time period, which can provide an additional pressure relief channel for the liquid cooling system, so that part of the coolant refluxes or flows into the expansion tank, thereby reducing the pressure and improving the stability of the liquid cooling system.

[0053] It is understandable that the specific value of the second preset time period can be selected and adjusted by those skilled in the art. Specifically, the second preset time period in the embodiment of the present invention can be set between 5 seconds and 9 seconds.

[0054] In some embodiments, reference Figure 5 As shown, in the above embodiment, when the first pressure value is less than the first preset pressure value, in step S320, the infusion pump is started, the second operating gear of the infusion pump is adjusted to the first preset operating gear, and the solenoid valve is controlled to remain in the open state within the first preset time period, the following steps are also included but not limited to steps S410 to S420: Step S410: Acquire a second pressure value detected in real time by the pressure sensor.

[0055] Step S420: When the second pressure value is greater than or equal to the second preset pressure value, the infusion pump is controlled to stop running.

[0056] It can be understood that in the embodiment of steps S410 to S420, by operating the rehydration pump at the first preset operating gear and cooperating with the solenoid valve to balance the pressure of the liquid cooling system and replenish the circulating coolant, a second pressure value detected in real time by the pressure sensor is obtained, and the second pressure value is compared with the second preset pressure value. When the second pressure value is greater than or equal to the second preset pressure value, it indicates that the pressure at the liquid inlet end of the secondary side pipeline of the liquid cooling system is high at this time, and the rehydration pump is controlled to stop running, which not only prevents the pressure from continuing to rise and ensures the stable operation of the liquid cooling system, but also avoids wasting coolant.

[0057] In some embodiments, reference Figure 5 As shown, the control method of the liquid cooling system according to the embodiment of the present invention further includes but is not limited to the following steps S430: Step S430: When the second pressure value is less than the second preset pressure value, the infusion pump is started, the second operating gear of the infusion pump is adjusted to the first preset operating gear, and the solenoid valve is controlled to remain in an open state within a first preset time period.

[0058] It should be noted that in the embodiment of step S430, when the second pressure value is less than the second preset pressure value, indicating that the coolant flow activity in the liquid cooling system is insufficient and the pressure at the liquid inlet end of the secondary side pipeline is still low, the refill pump is controlled to continue to start and adjust its second operating gear to the first preset operating gear, and the solenoid valve is controlled to remain open for the first preset time period. The coordinated operation of the refill pump and the solenoid valve can timely replenish coolant to the liquid cooling system, allowing the coolant in the expansion tank and the liquid storage tank to cool and circulate, thereby increasing the pressure in the liquid cooling system and the coolant flow activity.

[0059] It should be noted that the specific value of the second preset pressure value in the above embodiment can be selected and adjusted by those skilled in the art. Specifically, the value range of the second preset pressure value in the embodiment of the present invention can be between 0.8 bar and 1.0 bar.

[0060] In some embodiments, reference Figure 6 As shown, in the above embodiment, after the first pressure value is greater than or equal to the first preset pressure value in step S330, the solenoid valve is controlled to remain in the open state within the second preset time period, the following steps are also included but not limited to: Step S510: Acquire a third pressure value detected in real time by the pressure sensor.

[0061] Step S520: When the third pressure value is greater than or equal to the third preset pressure value, the first operating gear of at least one circulation pump, the operating state of the solenoid valve, and the second operating gear of the infusion pump are obtained again.

[0062] It can be understood that in the embodiments of steps S510 to S520, by controlling the solenoid valve to remain in an open state within the second preset time period, a third pressure value detected in real time by the pressure sensor is obtained, and the third pressure value is compared with the third preset pressure value. When the third pressure value is greater than or equal to the third preset pressure value, it indicates that the pressure at the liquid inlet end of the secondary side pipeline of the liquid cooling system is still high at this time, then the process returns to step S100 of the above embodiment, and the first operating gear of at least one circulating pump, the operating state of the solenoid valve and the second operating gear of the fluid replenishment pump are obtained again. It is necessary to readjust the dynamic active water parameters and control the solenoid valve and the fluid replenishment pump, that is, repeat steps S100 to S300 of the above embodiment. The embodiments of the present invention will not be repeated here.

[0063] In some embodiments, reference Figure 6 As shown, the control method of the liquid cooling system according to the embodiment of the present invention further includes but is not limited to the following steps S530: Step S530: When the third pressure value is less than the third preset pressure value, the infusion pump is started, the second operating gear of the infusion pump is adjusted to the second preset operating gear, and the operating time of the infusion pump is set to the third preset time period.

[0064] It should be noted that in the embodiment of step S530, by comparing the third pressure value with the third preset pressure value, if the third pressure value is less than the third preset pressure value, it indicates that the coolant flow activity of the liquid cooling system is insufficient and the pressure at the liquid inlet end of the secondary side pipeline is low. In this case, it is necessary to start the refill pump, adjust the second operating gear of the refill pump to the second preset operating gear, and set the operating time of the refill pump to the third preset time period. By timely starting the refill pump and adjusting it to the appropriate operating gear, the refill pump and the solenoid valve operate in coordination, quickly replenishing the coolant, allowing the coolant in the expansion tank and the liquid storage tank to cool and circulate, thereby increasing the pressure of the liquid cooling system and the flow activity of the coolant, and ensuring the reliable operation of the liquid cooling system.

[0065] It should be noted that the specific values ​​of the third preset pressure value, the second preset operating gear and the third preset time period can be selected and adjusted by those skilled in the art. Specifically, the value range of the third preset pressure value in the embodiment of the present invention can be between 0.7 bar and 0.9 bar, the third preset time period can be set between 7 seconds and 12 seconds, and the range of the third preset operating gear can be set between 2 gears and 3 gears. The motor output frequency corresponding to the specific gear can refer to the relevant contents of the above-mentioned steps S100 to S300 embodiments, which will not be repeated here.
