Description

Technical Field

[0002] With the rapid development of technologies such as artificial intelligence and big data, as a computing power infrastructure, the scale of the intelligent computing center is continuously expanding, the computing power density is continuously increasing, and higher requirements are put forward for the cooling system. The intelligent computing center usually includes key components such as computing devices, network devices, storage devices, and power supply devices. The devices in the intelligent computing center generate a large amount of heat during operation. Therefore, these devices that generate a large amount of heat in the intelligent computing center can also be called heat sources. If these heats cannot be effectively managed, it may cause the devices to overheat, thereby affecting performance, increasing the failure rate, and shortening the hardware life. In order to ensure that the devices operate within the optimal temperature range, the intelligent computing center abandons the inefficient air-cooled heat dissipation system and generally adopts an efficient liquid cooling system to meet the strict heat dissipation requirements and ensure the reliability and efficient operation of the intelligent computing center.

[0044] In the following description, specific details such as specific system structures and technologies are proposed for the purpose of illustration rather than limitation, so as to thoroughly understand the embodiments of the present invention. However, those skilled in the art should clearly understand that the present invention can also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to avoid unnecessary details from interfering with the description of the present invention.

[0045] To make the objectives, technical solutions, and advantages of the present invention clearer, the following will be described through specific embodiments with reference to the accompanying drawings.

[0046] Referring to Figure 1 , which shows a schematic structural diagram 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 from the heat source; the power supply system supplies power to the heat source.

[0047] Referring to 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 a cooling medium to the heat source according to the liquid supply control command to refrigerate, cool down, and dissipate heat from the heat source, so that the heat source can work within a normal temperature range, avoiding affecting the performance and lifespan of the heat source, etc.

[0048] Among them, 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 velocity control command to control the flow rate or velocity of the cooling medium; etc. The cooling medium may be water or an ethylene glycol aqueous solution, etc., or other coolable media, which are not specifically limited herein.

[0049] The heat source may be a device that needs to dissipate heat in the intelligent computing center, and may also be referred to as a load. For example, the heat source may be at least one of devices such as computing devices, network devices, storage devices, and power supply devices. The computing device may include at least one of devices such as a central processing unit, a graphics processing unit, a tensor processing unit, a field programmable gate array, and a server; the network device may include at least one of devices such as a switch and a router; the storage device may include at least one of devices such as a hard disk and a storage controller; the power supply device may include at least one of devices such as a power distribution unit, an uninterruptible power supply, and an energy storage device.

[0050] The control device may be a controller, such as a DSP (Digital Signal Processor) or other controllers, or may be a controller in the liquid cooling system, etc.

[0051] In the intelligent computing center, the power supply system may supply power to the heat source. The control device may obtain the power supply power of the power supply system for the heat source, and then generate a liquid supply control command according to the power supply power and send it to the liquid cooling unit. The liquid cooling unit supplies liquid to refrigerate the heat source based on the liquid supply control command, so that the heat source achieves the purpose of cooling and heat dissipation.

[0052] Next, based on Figure 1 , in combination with Figure 2A description is given of the control method for the liquid cooling system provided in the embodiments of the present application.

[0053] Refer to Figure 2 , which shows the implementation flowchart of the control method for the liquid cooling system with cold-electricity linkage provided in the embodiments of the present invention. The execution subject of the control method for the liquid cooling system with cold-electricity linkage is the control device.

[0054] As shown by Figure 1 , the liquid cooling system dissipates heat for the heat source, and the heat source is powered by the power supply system. Refer to Figure 2 , and the method is described in detail as follows:

[0055] In S101, obtain the power supply power of the power supply system to the heat source.

[0056] The heat source in the embodiments of the present application is a device that absorbs heat by the liquid cooling unit in the liquid cooling system, and may include at least one heat dissipation device in the intelligent computing center. For example, it may include at least one of the above-mentioned devices such as computing devices, network devices, storage devices, and power supply devices.

[0057] Refer to Figure 1 , and based on the power supply system, power supply power collection can be performed to obtain the power supply power of the power supply system to the heat source. In practical applications, the power supply frequency when the power supply system powers the heat source can be obtained through any feasible method. For example, the power supply power of the power supply system to the heat source can be directly measured by a power meter or a multifunctional meter; it can also be to measure the voltage and current of the heat source and calculate the power supply power through the voltage and current; and so on.

[0058] When the above heat source includes multiple devices, the power supply power of the heat source can be the sum of the power supply powers of the multiple devices. For example, if the liquid cooling unit cools and dissipates heat for multiple devices, then the above heat source includes the multiple devices.

[0059] It should be noted that the embodiments of the present application can obtain the real-time power supply power of the power supply system to the heat source, or obtain the power supply power of the power supply system to the heat source once per cycle. The duration of this cycle can be set according to actual needs. For example, it can be the set duration mentioned later, or longer or shorter than the set duration.

[0060] In S102, determine the heat generated by the heat source within the set duration according to the power supply power.

[0061] The embodiments of the present application can determine the heat generated by the heat source within the set duration according to the power supply power, so as to determine 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 later, enabling the liquid cooling unit to promptly respond to the rapid increase in the heat dissipation demand brought about by the rapid growth of the power consumption of the heat source.

[0062] Among them, in order to enable the liquid cooling system to respond quickly, the set duration can be a relatively short duration, and the specific value of the set duration can be set according to actual requirements, and no specific limitation is made here.

[0063] In S103, based on the heat, determine the temperature compensation value of the liquid cooling system.

[0064] Among them, the temperature compensation value of the liquid cooling system can specifically be the 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.

[0065] 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 heat source within the set duration, so as to compensate the initial set temperature of the liquid cooling system.

[0066] In S104, compensate the initial set temperature of the liquid cooling system according to the temperature compensation value to obtain the final set temperature, and control the liquid cooling system according to the final set temperature.

[0067] Among them, the initial set temperature of the liquid cooling system can also be called 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 considering the influence of the aforementioned heat. The final set temperature is the set temperature of the cooling medium in the liquid cooling system (or liquid cooling unit) after considering the influence of the aforementioned heat, that is, the set temperature obtained by compensating the above initial set temperature through the above temperature compensation value, and can also be called the target set temperature.

[0068] Control the liquid cooling unit in the liquid cooling system through the final set temperature, so that the temperature of the cooling medium in the liquid cooling unit meets the above final set temperature.

[0069] The embodiment of the present application determines the heat generated by the heat source within the set duration through the power supply power of the power supply system to the heat source, and then can determine the temperature compensation value of the liquid cooling system according to the heat, and compensate the initial set temperature of the liquid cooling system according to the temperature compensation value to obtain the final set temperature, and control the liquid cooling system with the final set temperature, so as to compensate the set temperature of the liquid cooling system based on the power consumption change of the heat source, so that the liquid cooling system can respond in time to the heat dissipation requirements brought by the rapid change of the power consumption of the heat source, and avoid the temperature of the heat source being too high and affecting the performance.

[0070] The overall implementation process of the control method of the liquid cooling system with cold-electricity linkage is introduced in the above embodiment, which involves determining the temperature compensation value of the liquid cooling system based on the heat. The following details how to determine the temperature compensation value of the liquid cooling system according to the above heat.

[0071] In some embodiments, the above S103 may include:

[0072] Based on the heat, determine the compensation temperature for the power quantity and the compensation temperature for the power sudden change quantity.

[0073] Determine the temperature compensation value of the liquid cooling system according to the compensation temperature for the power quantity and the compensation temperature for the power sudden change quantity.

[0074] 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 quantity and the compensation temperature for the power sudden change quantity. Among them, the compensation temperature for the power quantity can also be called the response temperature for the power quantity, and the compensation temperature for the power sudden change quantity can also be called the response temperature for the power sudden change quantity.

[0075] Since heat is generated by power during the operation of the heat source and heat sudden change is caused by power sudden change, therefore, the embodiment of the present application has targeted response temperatures for both situations to absorb the heat generated by both situations.

[0076] Among them, the compensation temperature for the power quantity can be understood as the temperature compensation value based on the power quantity, specifically representing the response temperature corresponding to the cooling capacity required by the power, characterizing the response to the power quantity; the compensation temperature for the power sudden change quantity can be understood as the temperature compensation value based on the power sudden change quantity, specifically representing the response temperature corresponding to the cooling capacity required by the power sudden change, characterizing the response to the dynamic performance.

[0077] In some embodiments, the above-mentioned determining the compensation temperature for the power quantity and the compensation temperature for the power sudden change quantity based on the heat includes:

[0078] According to , determine the compensation temperature for the power quantity ; where is the heat, is the compensation coefficient for the power quantity;

[0079] According to , determine the compensation temperature for the power sudden change quantity ; where is the compensation coefficient for the power sudden change quantity; is the differential of the heat, and can also be understood as the change rate of the heat with time.

[0080] Among them, the compensation coefficient for the power quantity and the compensation coefficient for the power sudden change quantity can be determined through corresponding tests or according to corresponding experience, and no specific limitation is made here.

[0081] In some embodiments, the above-mentioned determining the temperature compensation value of the liquid cooling system according to the compensation temperature for the power quantity and the compensation temperature for the power sudden change quantity includes:

[0082] The sum of the compensation temperature for the power quantity and the compensation temperature for the power mutation quantity is used as the temperature compensation value of the liquid cooling system.

[0083] Based on the heat generated by the heat source within a set time period in the embodiments of the present application, the compensation temperature for the power quantity and the compensation temperature for the power mutation quantity are respectively determined, and based on the compensation temperature for the power quantity and the compensation temperature for the power mutation quantity, the temperature compensation value of the liquid cooling system is determined, which can make the finally determined final set temperature respond to both the power and dynamic performance of the heat source, meeting the liquid cooling requirements of the heat source.

[0084] On the basis of the foregoing embodiments, the above S103 may further include:

[0085] Compare the absolute value of the heat with the size of the preset detection dead zone;

[0086] 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;

[0087] Correspondingly, the above determining the compensation temperature for the power quantity and the compensation temperature for the power mutation quantity based on the heat includes:

[0088] If the absolute value of the heat is greater than the preset detection dead zone, then based on the heat, determine the compensation temperature for the power quantity and the compensation temperature for the power mutation quantity.

[0089] Among them, the size of the preset detection dead zone can be determined according to relevant engineering experience.

[0090] When the absolute value of the heat is less than or equal to the preset detection dead zone, it indicates that the heat is small, and it may not be necessary to respond to it or the minimum response temperature of the liquid cooling system cannot be reached (that is, absorbing this heat may not cause a change in temperature). Therefore, 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, at this time the heat is large, reaching the minimum response temperature of the liquid cooling system, and the temperature compensation value can be calculated based on the method of the foregoing embodiments.

[0091] Next, continue to introduce how to determine the heat generated by the heat source within a set time period according to the power supply.

[0092] In some embodiments, the above S102 may include:

[0093] Perform sliding integration on the power supply to determine the heat generated by the heat source within a set time period.

[0094] In the embodiments of the present application, every 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 performing an integration operation on a signal within a time window, and this window continuously slides forward as time goes by. The duration of the time window for the sliding integration is the above-mentioned set time period.

[0095] In some embodiments, the above-mentioned performing a sliding integration on the power supply power to determine the heat generated by the heat source within a set time period includes:

[0096] According to , determine the heat generated by the heat source within the set time period ; where is the power supply power, is the set time period, is the start time of the set time period.

[0097] The time window in the embodiments of the present application is from t to ; where t changes as time changes.

[0098] In some embodiments, in S104, the above-mentioned compensating the initial set temperature of the liquid cooling system according to the temperature compensation value to obtain the final set temperature includes:

[0099] Take the sum of the temperature compensation value and the initial set temperature as the final set temperature.

[0100] In some possible implementation manners, in the above S104, after compensating the initial set temperature of the liquid cooling system according to the temperature compensation value to obtain the final set temperature, it may further include:

[0101] Perform a clipping process on the final set temperature, and use the clipped final set temperature as the final target set temperature;

[0102] Correspondingly, in the above S104, controlling the liquid cooling system according to the final set temperature includes:

[0103] Control the liquid cooling system according to the above-mentioned final target set temperature.

[0104] In some possible implementation manners, after the above S103, it may further include:

[0105] Perform a clipping process on the above temperature compensation value to obtain the clipped temperature compensation value;

[0106] 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:

[0107] Compensating the initial set temperature of the liquid cooling system according to the temperature compensation value after amplitude limiting processing to obtain the final set temperature.

[0108] Among them, the amplitude limiting processing may adopt the amplitude limiting method in related technologies 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.

[0109] For example, if the temperature compensation value is greater than the corresponding preset maximum value, the temperature compensation value after amplitude 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 amplitude 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 amplitude limiting processing is still the above temperature compensation value.

[0110] Similarly, if the final set temperature is greater than the corresponding preset maximum value, the final set temperature after amplitude 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 amplitude 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 amplitude limiting processing is still the above final set temperature.

[0111] 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 no specific limitation is made here.

[0112] The liquid cooling system control method with cold-electricity linkage provided by the embodiments of the present application can improve the cooling capacity response speed of the liquid cooling system through the feedback of the power consumption of the heat source; determining the temperature compensation value based on the proportional plus derivative method can improve the dynamic performance of the liquid cooling system.

[0113] It should be understood that the magnitudes of the sequence numbers of the steps in the above embodiments do not mean the order of execution. The execution order of each process should be determined according to its function and internal logic, and should not constitute any limitation to the implementation process of the embodiments of the present invention.
