However, it should be clear to those skilled in the art that the present invention may be implemented in other embodiments without these specific details.

[0022] In order to make the purpose, technical solutions and advantages of the present invention more clear, specific embodiments will be described below in conjunction with the accompanying drawings.

[0023] See also Figure 1 , which shows a schematic diagram of the structure of an intelligent computing center provided by an embodiment of the present invention. The intelligent computing center includes a power supply system, a heat source and a liquid cooling system; the liquid cooling system dissipates heat for the heat source; and the power supply system supplies power to the heat source.

[0024] See also Figure 1 The liquid cooling system may include a control device and a liquid cooling unit, and the liquid cooling unit is controlled by the control device. Specifically, the control device may send a liquid supply control command to the liquid cooling unit, and the liquid cooling unit provides cooling medium to the heat source according to the liquid supply control command to cool, reduce the temperature, and dissipate heat for the heat source, so that the heat source can work within a normal temperature range, avoiding affecting the performance and life of the heat source, etc.

[0025] The liquid supply control command may be a temperature control command to control the temperature of the cooling medium, for example, it may include the final set temperature mentioned later; the liquid supply control command may also be a flow rate or flow velocity control command to control the flow rate or flow velocity of the cooling medium; etc. The cooling medium may be water or ethylene glycol aqueous solution, or other coolable medium, which is not specifically limited here.

[0026] The heat source can be a device in the intelligent computing center that needs to dissipate heat, which can also be called a load. For example, the heat source can be at least one of computing devices, network devices, storage devices, and power devices. Computing devices can include at least one of central processing units, graphics processing units, tensor processing units, field programmable gate arrays, and servers; network devices can include at least one of switches and routers; storage devices can include at least one of hard disks and storage controllers; power devices can include at least one of power distribution units, uninterruptible power supplies, and energy storage devices.

[0027] The control device may be a controller, such as a DSP (Digital Signal Processor) or the like, or may be a controller in a liquid cooling system, and the like.

[0028] In the intelligent computing center, the power supply system can supply power to the heat source. The control device can obtain the power supplied by the power supply system to the heat source, and then generate a liquid supply control command based on the power supply and send it to the liquid cooling unit. The liquid cooling unit supplies liquid to the heat source based on the liquid supply control command, so that the heat source can achieve the purpose of cooling and dissipating heat.

[0029] The following is based on Figure 1 , combined with Figure 2 The control method of the liquid cooling system provided in the embodiment of the present application is described.

[0030] See also Figure 2 , which shows an implementation flow chart of a cold-electricity-coupled liquid cooling system control method provided by an embodiment of the present invention, wherein the execution subject of the cold-electricity-coupled liquid cooling system control method is a control device.

[0031] Depend on Figure 1 As shown, the liquid cooling system dissipates heat from the heat source, and the heat source is powered by the power supply system. Figure 2 , the method is described in detail as follows: In S101, the power supplied by the power supply system to the heat source is obtained.

[0032] The heat source in the embodiment of the present application is a device whose heat is absorbed by the liquid cooling unit in the liquid cooling system, and may include at least one device that requires heat dissipation in the intelligent computing center, for example, it may include at least one of the above-mentioned computing devices, network devices, storage devices, and power supply devices.

[0033] See also Figure 1 , based on the power supply system, power supply power can be collected to obtain the power supply of the power supply system to the heat source. In practical applications, the power supply frequency when the power supply system supplies power to the heat source can be obtained in any feasible way. For example, the power supply of the power supply system to the heat source can be directly measured by a power meter or a multi-function meter; or the voltage and current of the heat source can be measured, and the power supply can be calculated by the voltage and current; and so on.

[0034] When the heat source includes multiple devices, the power supply of the heat source may be the sum of the power supplies of the multiple devices. For example, if a liquid cooling unit cools and dissipates heat for multiple devices, the heat source includes the multiple devices.

[0035] It should be noted that the embodiment of the present application can obtain the real-time power supply of the power supply system to the heat source, or can obtain the power supply of the power supply system to the heat source once per cycle. The duration of the cycle can be set according to actual needs, for example, it can be the set duration mentioned later, or it can be longer or shorter than the set duration.

[0036] In S102, the amount of heat generated by the heat source within a set time period is determined according to the power supply.

[0037] The embodiment of the present application can determine the heat generated by the heat source within a set time period based on the power supply power, thereby determining the heat that the cooling medium in the liquid cooling unit needs to absorb. The above heat can reflect the power consumption change of the heat source, so that the temperature compensation value of the liquid cooling unit can be determined based on the above heat, so that the liquid cooling unit can promptly respond to the rapid increase in heat dissipation demand caused by the rapid growth of power consumption of the heat source.

[0038] In order to enable the liquid cooling system to respond quickly, the set time length can be a shorter time length. The specific value of the set time length can be set according to actual needs and is not specifically limited here.

[0039] In S103 , a temperature compensation value of the liquid cooling system is determined based on the heat.

[0040] The temperature compensation value of the liquid cooling system may specifically be a temperature compensation value of the liquid cooling unit, which refers to the temperature that the liquid cooling unit needs to compensate for the power consumption change of the heat source.

[0041] The embodiment of the present application can determine the temperature compensation value of the liquid cooling system based on the heat generated by the above-mentioned heat source within a set time period, so as to compensate for the initial set temperature of the liquid cooling system.

[0042] In S104, the initial set temperature of the liquid cooling system is compensated according to the temperature compensation value to obtain a final set temperature, and the liquid cooling system is controlled according to the final set temperature.

[0043] The initial set temperature of the liquid cooling system may also be referred to as the initial set temperature of the liquid cooling unit, which is the set temperature of the cooling medium in the liquid cooling system (or liquid cooling unit) before the influence of the aforementioned heat is considered. The final set temperature is the set temperature of the cooling medium in the liquid cooling system (or liquid cooling unit) after the influence of the aforementioned heat is considered, that is, the set temperature after the initial set temperature is compensated by the aforementioned temperature compensation value, which may also be referred to as the target set temperature.

[0044] The liquid cooling unit in the liquid cooling system is controlled by the final set temperature so that the temperature of the cooling medium in the liquid cooling unit meets the above-mentioned final set temperature.

[0045] The embodiment of the present application determines the amount of heat generated by the heat source within a set period of time by supplying the power of the heat source to the power supply system, and then determines the temperature compensation value of the liquid cooling system based on the heat, and compensates the initial set temperature of the liquid cooling system based on the temperature compensation value to obtain the final set temperature. The liquid cooling system is controlled with the final set temperature, so that the set temperature of the liquid cooling system can be compensated based on the power consumption change of the heat source, so that the liquid cooling system can respond in time to the heat dissipation demand caused by the rapid change in the power consumption of the heat source, and avoid the temperature of the heat source being too high and affecting the performance.

[0046] The above embodiment introduces the overall implementation process of the cold-electric coupled liquid cooling system control method, which involves determining the temperature compensation value of the liquid cooling system based on heat. The following describes in detail how to determine the temperature compensation value of the liquid cooling system based on the above heat.

[0047] In some embodiments, the above S103 may include: Based on the heat, determining a compensation temperature for the power amount and a compensation temperature for the power sudden change amount; The temperature compensation value of the liquid cooling system is determined according to the compensation temperature for the power amount and the compensation temperature for the power mutation amount.

[0048] In the embodiment of the present application, the temperature compensation value of the liquid cooling system consists of two parts: the compensation temperature for the power amount and the compensation temperature for the power mutation amount. Among them, the compensation temperature for the power amount can also be called the response temperature for the power amount, and the compensation temperature for the power mutation amount can also be called the response temperature for the power mutation amount.

[0049] When the heat source is working, power will generate heat, and a sudden change in power will cause a sudden change in heat. Therefore, the embodiment of the present application has targeted response temperatures for both situations to absorb the heat generated in both situations.

[0050] Among them, the compensation temperature for power can be understood as a temperature compensation value based on the power, specifically indicating the response temperature corresponding to the cooling required for the power, and characterizing the response to the power; the compensation temperature for power mutation can be understood as a temperature compensation value based on the power mutation, specifically indicating the response temperature corresponding to the cooling required for the power mutation, and characterizing the dynamic performance response.

[0051] In some embodiments, the above-mentioned determination of the compensation temperature for the power amount and the compensation temperature for the power sudden change amount based on the heat includes: according to , determine the compensation temperature for the power quantity ;in, For heat, is the compensation coefficient for power; according to , determine the compensation temperature for power surge ;in, is the compensation coefficient for power mutation; It is the differential of heat, which can also be understood as the rate of change of heat over time.

[0052] Among them, the compensation coefficient for power And the compensation coefficient for power surge It can be determined through corresponding experiments or based on corresponding experience, and is not specifically limited here.

[0053] In some embodiments, the temperature compensation value of the liquid cooling system is determined according to the compensation temperature for the power amount and the compensation temperature for the power mutation amount, including: The sum of the compensation temperature for the power amount and the compensation temperature for the power mutation amount is used as the temperature compensation value of the liquid cooling system.

[0054] The embodiment of the present application determines the compensation temperature for the power amount and the compensation temperature for the power mutation amount based on the heat generated by the heat source within the set time, and determines the temperature compensation value of the liquid cooling system based on the compensation temperature for the power amount and the compensation temperature for the power mutation amount. The final set temperature can be finally determined, and at the same time respond to the power and dynamic performance of the heat source to meet the liquid cooling needs of the heat source.

[0055] Based on the above embodiment, the above S103 may further include: Compare the absolute value of heat with the size of the preset detection dead zone; If the absolute value of the heat is less than or equal to the preset detection dead zone, the temperature compensation value of the liquid cooling system is 0; Accordingly, the above method of determining the compensation temperature for the power amount and the compensation temperature for the power mutation amount based on the heat includes: If the absolute value of the heat is greater than the preset detection dead zone, a compensation temperature for the power amount and a compensation temperature for the power sudden change amount are determined based on the heat.

[0056] Among them, the size of the preset detection dead zone can be determined based on relevant engineering experience.

[0057] When the absolute value of the heat is less than or equal to the preset detection dead zone, it means that the heat is small, and it may not be responded to or the minimum response temperature of the liquid cooling system may not be reached (that is, the temperature may not change after absorbing the heat), so the temperature compensation value of the liquid cooling system is 0. When the absolute value of the heat is greater than the preset detection dead zone, the heat is large at this time, and the minimum response temperature of the liquid cooling system is reached, and the temperature compensation value can be calculated based on the method of the above embodiment.

[0058] The following will continue to introduce how to determine the amount of heat generated by a heat source within a set time period based on the power supply.

[0059] In some embodiments, the above S102 may include: Perform a sliding integration of the supplied power to determine the heat generated by the heat source within a set time period.

[0060] In the embodiment of the present application, each time the power supply power of the heat source is collected, a sliding integration is performed on the power supply power to determine the heat generated by the heat source within a set time period. The sliding integration refers to the integration operation of the signal within a time window, and the window will continue to slide forward as time goes by. The duration of the time window of the sliding integration is the above-mentioned set duration.

[0061] In some embodiments, the above-mentioned sliding integration of the power supply to determine the heat generated by the heat source within a set time period includes: according to , determine the heat generated by the heat source within a set time ;in, is the power supply, For the set duration, The starting time of the set duration.

[0062] The time window of the embodiment of the present application is from t arrive ;in, t Changes with time.

[0063] In some embodiments, in S104, compensating the initial set temperature of the liquid cooling system according to the temperature compensation value to obtain the final set temperature includes: The sum of the temperature compensation value and the initial set temperature is taken as the final set temperature.

[0064] In some possible implementations, in the above S104, after the initial set temperature of the liquid cooling system is compensated according to the temperature compensation value to obtain the final set temperature, the following may also be included: The final set temperature is limited, and the final set temperature after the limit processing is used as the final target set temperature; Accordingly, in the above S104, the liquid cooling system is controlled according to the final set temperature, including: The liquid cooling system is controlled according to the above final target set temperature.

[0065] In some possible implementations, after the above S103, the following steps may also be included: Performing a limiting process on the temperature compensation value to obtain a temperature compensation value after the limiting process; Accordingly, in the above S104, compensating the initial set temperature of the liquid cooling system according to the temperature compensation value to obtain the final set temperature may include: The initial set temperature of the liquid cooling system is compensated according to the temperature compensation value after the limiting process to obtain the final set temperature.

[0066] The limiting process may adopt a limiting method in the related art to prevent the temperature compensation value or the final set temperature from being greater than the corresponding preset maximum value or less than the corresponding preset minimum value.

[0067] For example, if the temperature compensation value is greater than the corresponding preset maximum value, the temperature compensation value after limiting processing is its corresponding preset maximum value; if the temperature compensation value is less than the corresponding preset minimum value, the temperature compensation value after limiting processing is its corresponding preset minimum value; if the temperature compensation value is between the corresponding preset minimum value and the corresponding preset maximum value, the temperature compensation value after limiting processing is still the above temperature compensation value.

[0068] Similarly, if the final set temperature is greater than the corresponding preset maximum value, the final set temperature after limiting processing is its corresponding preset maximum value; if the final set temperature is less than the corresponding preset minimum value, the final set temperature after limiting processing is its corresponding preset minimum value; if the final set temperature is between the corresponding preset minimum value and the corresponding preset maximum value, the final set temperature after limiting processing is still the above-mentioned final set temperature.

[0069] Among them, the preset maximum value and the preset minimum value corresponding to the temperature compensation value and the final set temperature respectively can be set according to actual needs and are not specifically limited here.

[0070] The cold-electric coupled liquid cooling system control method provided in the embodiment of the present application can improve the cooling response speed of the liquid cooling system by feedback of the electrical power consumption of the heat source; and can improve the dynamic performance of the liquid cooling system by determining the temperature compensation value based on the proportional plus differential method.

[0071] It should be understood that the order of execution of the steps in the above embodiment does not necessarily mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiment of the present invention.
