Description

Technical Field

[0001] This invention relates to the field of liquid cooling system control technology, and in particular to an intelligent control method and device for the temperature of a liquid cooling system. Background Technology

[0002] Currently, when it is necessary to adjust the outlet temperature of a liquid cooling system, this is often achieved by adjusting the regulating valve within the liquid cooling system.

[0003] However, practical experience has shown that existing liquid cooling systems, which rely on a single valve for regulation, increase system resistance, especially when flow requirements are low, leading to inaccurate temperature control. Therefore, proposing a technical solution to improve the accuracy of temperature regulation in liquid cooling systems is of paramount importance. Summary of the Invention

[0088] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0089] The terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this invention are used to distinguish different objects, not to describe a specific order. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, apparatus, product, or end that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products, or ends.

[0090] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0091] This invention discloses an intelligent temperature control method and device for a liquid cooling system. By controlling the flow rate of the liquid cooling system through dual regulating valves, the resistance of the liquid cooling system can be reduced, the power consumption of the external power pump can be lowered, and the heat exchange efficiency of the heat exchanger can be improved. Even with small flow rate adjustments, precise regulation of the outlet temperature of the liquid cooling system can be achieved, while improving the operational smoothness of other units in the same ring network. Furthermore, even if there are sudden changes in load, the outlet temperature of the liquid cooling system can be controlled to change slowly through the dual regulating valves, shortening the time it takes for the outlet temperature to stabilize. Detailed descriptions follow.

[0092] Example 1

[0093] Please see Figure 1 , Figure 1 This is a flowchart illustrating an intelligent temperature control method for a liquid cooling system disclosed in an embodiment of the present invention. Wherein, Figure 1 The described method can be applied to intelligent control devices for the temperature of liquid cooling systems. These intelligent control devices include one or more of the following: an intelligent control system, an intelligent control server, intelligent control equipment, and the liquid cooling system itself. The intelligent control server can be a local server or a cloud server. Figure 1 As shown, the intelligent temperature control method for this liquid cooling system may include the following operations:

[0094] 101. Collect load data of the heat exchanger in the liquid cooling system, and determine the load change of the heat exchanger based on the collected load data.

[0095] 102. Based on the load changes of the heat exchanger, determine the control mode of the regulating valve that matches the load changes of the heat exchanger.

[0096] 103. Based on the determined control mode of the regulating valve, control the first regulating valve and the second regulating valve of the liquid cooling system to perform matching temperature regulation operations.

[0097] In this embodiment of the invention, when the load change of the heat exchanger is used to indicate that the degree of load change of the heat exchanger is less than or equal to a preset change threshold, the regulating valve control mode that matches the load change of the heat exchanger is the first regulating valve control mode; when the load change of the heat exchanger is used to indicate that the degree of load change of the heat exchanger is greater than the preset change threshold, the regulating valve control mode that matches the load change of the heat exchanger is the second regulating valve control mode.

[0098] In embodiments of the present invention, such as Figure 6 As shown, Figure 6 This is a schematic diagram of the structure of a liquid cooling system disclosed in an embodiment of the present invention, as shown below. Figure 6 As shown, the liquid cooling system includes a first regulating valve 1, a second regulating valve 2, a heat exchanger, and a temperature sensor. The temperature sensor measures the outlet temperature of the liquid cooling system, and there is at least one temperature sensor. The first and second regulating valves regulate the flow rate, facilitating heat exchange and thus regulating the outlet temperature of the liquid cooling system. By connecting the two regulating valves in parallel, one side of the pipeline is kept in a state of minimum resistance. Controlling both valves simultaneously improves the accuracy of flow rate control, thereby improving the accuracy of outlet temperature control. It should be noted that the first and second regulating valves can be two-way or three-way regulating valves. The second regulating valve can be replaced by a shut-off valve. The position of the first regulating valve can be as follows... Figure 6 As shown, the plate heat exchanger outlet can also be the plate heat exchanger inlet. When located at the plate heat exchanger outlet, it can be located before or after the parallel loop.

[0099] It is evident that implementation Figure 1 The described intelligent temperature control method for the liquid cooling system can regulate the flow rate of the liquid cooling system by controlling dual regulating valves, which can reduce the resistance of the liquid cooling system, reduce the power consumption of the external power pump, and improve the heat exchange efficiency of the heat exchanger. Even with small flow rate regulation, the outlet temperature of the liquid cooling system can be accurately regulated, while improving the smooth operation of other units in the same ring network. Even if the load changes suddenly, the outlet temperature of the liquid cooling system can be controlled to change slowly by the dual regulating valves, shortening the time for the outlet temperature to stabilize.

[0100] In an optional embodiment, when the control mode of the regulating valve is the first regulating valve control mode, the first regulating valve and the second regulating valve of the liquid cooling system are controlled to perform matching temperature regulation operations according to the determined regulating valve control mode, including:

[0101] Control the first regulating valve to be fully closed and the second regulating valve to be fully open, and obtain the first outlet temperature of the liquid cooling system;

[0102] Determine whether the first outlet temperature of the liquid cooling system is greater than or equal to the preset temperature. When it is determined that the first outlet temperature of the liquid cooling system is greater than or equal to the preset temperature, control the second regulating valve to remain fully open and control the first regulating valve to gradually open until the first regulating valve is fully open.

[0103] The system collects the second outlet temperature of the liquid cooling system when the first regulating valve is fully open, and determines whether the second outlet temperature of the liquid cooling system is greater than or equal to the preset temperature. When the determination result is yes, the system controls the first regulating valve to be fully open and controls the second regulating valve to gradually close.

[0104] During the process of gradually closing the second regulating valve, the third outlet temperature of the liquid cooling system is collected, and the first and second regulating valves are controlled according to the third outlet temperature of the liquid cooling system.

[0105] During the process of controlling the first and second regulating valves based on the third outlet temperature of the liquid cooling system, the fourth outlet temperature of the liquid cooling system is collected. When the fourth outlet temperature of the liquid cooling system is less than or equal to the preset temperature and the second regulating valve is in the fully open state, the second regulating valve is controlled to remain fully open, and the first regulating valve is controlled to gradually close.

[0106] As can be seen, this optional embodiment can precisely control the dual regulating valve based on the comparison between the outlet temperature of the liquid cooling system and the set temperature when the load change of the heat exchanger of the liquid cooling system is small. During the control process, the outlet temperature of the liquid cooling system is still monitored in real time, and the dual regulating valve is controlled in turn based on the real-time monitoring results, thereby achieving precise flow regulation and thus precise control of the outlet temperature.

[0107] In this optional embodiment, controlling the first regulating valve and the second regulating valve according to the third outlet temperature of the liquid cooling system includes:

[0108] When the temperature at the third outlet of the liquid cooling system is lower than the preset temperature, the first regulating valve is controlled to maintain its current state and the second regulating valve is controlled to gradually open.

[0109] When the third outlet temperature of the liquid cooling system equals the preset temperature, control the first regulating valve and the second regulating valve to maintain the current state.

[0110] When the temperature at the third outlet of the liquid cooling system exceeds the preset temperature, the second regulating valve is gradually closed.

[0111] As can be seen, in the process of adjusting the dual regulating valve, this optional embodiment still performs fine control of the dual regulating valve by comparing the monitored outlet temperature and the set temperature, thereby further improving the accuracy of flow regulation, improving the accuracy and efficiency of heat exchanger contact with flow, and thus improving the heat exchange efficiency and accuracy of heat exchanger.

[0112] In another optional embodiment, when the control mode of the regulating valve is the second regulating valve control mode, the first regulating valve and the second regulating valve of the liquid cooling system are controlled to perform matching temperature regulation operations according to the determined regulating valve control mode, including:

[0113] Collect the spatial temperature of the space where the liquid cooling system is located, and compare the change value of the spatial temperature of the space where the liquid cooling system is located with the preset spatial change threshold to obtain the comparison result;

[0114] When the comparison result indicates that the change in the space temperature of the liquid cooling system is greater than or equal to the preset space change threshold, the fifth outlet temperature of the liquid cooling system is collected.

[0115] Determine whether the fifth outlet temperature of the liquid cooling system is greater than or equal to the preset temperature. If the determination result is yes, control the first regulating valve to gradually open and control the second regulating valve to gradually close until the second regulating valve is completely closed.

[0116] The first regulating valve is controlled to operate based on the space temperature of the liquid cooling system and the fifth outlet temperature of the liquid cooling system, while the second regulating valve is kept closed. The sixth outlet temperature of the liquid cooling system is continuously collected, and when the sixth outlet temperature of the liquid cooling system is lower than the preset temperature, the first regulating valve is controlled to gradually close, while the second regulating valve is controlled to gradually open until the second regulating valve is fully open.

[0117] The method may also include the following steps:

[0118] When the second regulating valve is fully open, the space temperature of the liquid cooling system is collected, and the second regulating valve control mode is exited when the change value of the space temperature of the liquid cooling system is greater than or equal to the preset space temperature stability value.

[0119] As can be seen, when the load of the heat exchanger in the liquid cooling system changes significantly, this optional embodiment can use a matching adjustment mode to precisely control the dual regulating valves according to the comparison between the outlet temperature of the liquid cooling system and the set temperature. During the control process, the outlet temperature of the liquid cooling system is still monitored in real time, and the dual regulating valves are controlled in turn based on the real-time monitoring results, thereby achieving precise flow regulation and precise control of the outlet temperature.

[0120] In yet another optional embodiment, the method may further include the following steps:

[0121] During the process of controlling the first and second regulating valves based on the first regulating valve control mode or the second regulating valve control mode, it is determined whether the collected seventh outlet temperature of the liquid cooling system is less than or equal to the preset dew point temperature. When the determination result is yes, the first regulating valve is controlled to gradually close and the second regulating valve is controlled to gradually open.

[0122] During the process of controlling the first regulating valve and the second regulating valve, the outlet temperature of the liquid cooling system is monitored in real time to obtain the first monitoring result. When the first monitoring result indicates that the real-time monitored outlet temperature of the liquid cooling system is equal to the preset dew point temperature, the first regulating valve and the second regulating valve are controlled to maintain the current state.

[0123] Continue to monitor the outlet temperature of the liquid cooling system in real time to obtain a second monitoring result. When the second monitoring result indicates that the outlet temperature of the liquid cooling system is greater than the preset dew point temperature, control the first regulating valve to gradually open and control the second regulating valve to remain fully open.

[0124] As can be seen, in the process of controlling the outlet temperature of the liquid cooling system by the dual regulating valves, if the outlet temperature of the liquid cooling system is greater than the set dew point temperature, the dual regulating valves can be controlled to act simultaneously, which improves the accuracy and timeliness of flow regulation, thereby reducing the occurrence of water droplets on the server equipment, reducing the occurrence of damage to the server equipment, and improving the service life of the equipment.

[0125] Example 2

[0126] Please see Figure 2 , Figure 2 This is a flowchart illustrating another intelligent temperature control method for a liquid cooling system disclosed in an embodiment of the present invention. Figure 2 The described method can be applied to intelligent control devices for the temperature of liquid cooling systems. These intelligent control devices include one or more of the following: an intelligent control system, an intelligent control server, intelligent control equipment, and the liquid cooling system itself. The intelligent control server can be a local server or a cloud server. Figure 2 As shown, the intelligent temperature control method for this liquid cooling system may include the following operations:

[0127] 201. Collect load data of the heat exchanger in the liquid cooling system, and determine the load change of the heat exchanger based on the collected load data.

[0128] 202. Based on the load changes of the heat exchanger, determine the control mode of the regulating valve that matches the load changes of the heat exchanger.

[0129] 203. Based on the determined control mode of the regulating valve, control the first regulating valve and the second regulating valve of the liquid cooling system to perform matching temperature regulation operations.

[0130] 204.

[0131] 205. Determine the type of the faulty control valve, and determine the fault control mode that matches the type of the faulty control valve.

[0132] 206. Control the corresponding control valve according to the fault control mode that matches the type of fault control valve.

[0133] It should be noted that for other related descriptions of steps 201-203, please refer to the detailed description of steps 101-103 in Embodiment 1. These descriptions will not be repeated in this embodiment of the invention.

[0134] It is evident that implementation Figure 2 The described intelligent temperature control method for the liquid cooling system can regulate the flow rate of the liquid cooling system by controlling dual regulating valves. This reduces the resistance of the liquid cooling system, lowers the power consumption of the external power pump, and improves the heat exchange efficiency of the heat exchanger. Even with small flow rate adjustments, it can achieve precise regulation of the liquid cooling system's outlet temperature, while also improving the operational smoothness of other units in the same ring network. Furthermore, even with sudden load changes, the dual regulating valves can control the outlet temperature of the liquid cooling system to change slowly, shortening the time it takes for the outlet temperature to stabilize. In addition, during the control of the dual regulating valves, if one regulating valve malfunctions, the other regulating valve is precisely controlled based on the malfunctioning valve, thereby ensuring the stability of the liquid cooling system's outlet temperature and ensuring that the outlet temperature of the liquid cooling system is as close as possible to the required temperature.

[0135] In an optional embodiment, controlling the corresponding control valve according to a fault control mode that matches the type of fault control valve includes:

[0136] When the fault control valve is the first control valve, the first control valve is controlled to be fully open, and when the outlet temperature of the liquid cooling system is less than the preset temperature, the second control valve is controlled to gradually open; when the outlet temperature of the liquid cooling system is detected to be equal to the preset temperature, the second control valve is controlled to maintain the current state; when the outlet temperature of the liquid cooling system is detected to be greater than the preset temperature, the second control valve is controlled to gradually close.

[0137] When the fault control valve is the second control valve, the second control valve is controlled to be closed, and when the outlet temperature of the liquid cooling system is less than the preset temperature, the first control valve is controlled to gradually close; when the outlet temperature of the liquid cooling system is detected to be equal to the preset temperature, the first control valve is controlled to maintain its current state; when the outlet temperature of the liquid cooling system is detected to be greater than the preset temperature, the first control valve is controlled to gradually open.

[0138] As can be seen, this optional embodiment precisely controls another regulating valve based on the malfunctioning regulating valve, so as to ensure a stable output temperature of the liquid cooling system even when the regulating valve malfunctions.

[0139] In another alternative embodiment, the method may further include the following steps:

[0140] In all the above embodiments, during the process of controlling the first regulating valve and / or the second regulating valve, the flow rate of the pipeline between the first regulating valve and the heat exchanger and the flow rate before the second regulating valve and the heat exchanger are obtained, and the distance between the first regulating valve and the heat exchanger and the distance between the second regulating valve and the heat exchanger are determined.

[0141] Based on the distance and flow rate corresponding to the first regulating valve and the distance and flow rate corresponding to the second regulating valve, determine the total flow rate flowing to the heat exchanger per unit time, obtain the current heat exchange rate of the heat exchanger, and calculate the heat exchange when the total flow rate flows to the heat exchanger based on the current heat exchange rate of the heat exchanger.

[0142] Determine the impact of heat exchange with the current heat exchange capacity on the outlet temperature of the liquid cooling system, and determine whether the impact is greater than or equal to a preset impact threshold. If the determination result is yes, adjust the opening of the first regulating valve and the opening of the second regulating valve according to the distance and flow rate corresponding to the first regulating valve and the second regulating valve, the impact of the change, and the outlet temperature of the liquid cooling system. If the determination result is no, end the process.

[0143] In this optional embodiment, determining the distance between the first regulating valve and the heat exchanger and the distance between the second regulating valve and the heat exchanger includes:

[0144] The positions of the first regulating valve, the second regulating valve, and the heat exchanger in the liquid cooling system are determined. Based on the positions of the first regulating valve and the heat exchanger in the liquid cooling system, the distance between the first regulating valve and the heat exchanger is determined. Based on the positions of the second regulating valve and the heat exchanger in the liquid cooling system, the distance between the second regulating valve and the heat exchanger is determined.

[0145] In this optional embodiment, the method further includes the following steps:

[0146] The information obtained includes the piping conditions between the first regulating valve and the heat exchanger, and the piping conditions between the second regulating valve and the heat exchanger. The piping conditions include one or more of the following: piping material, piping direction, piping diameter, and piping curvature.

[0147] The total flow rate to the heat exchanger per unit time is determined based on the distance and flow rate corresponding to the first regulating valve and the distance and flow rate corresponding to the second regulating valve, including:

[0148] Based on the distance, pipeline conditions, and flow rate corresponding to the first regulating valve and the distance, pipeline conditions, and flow rate corresponding to the second regulating valve, determine the total flow rate to the heat exchanger per unit time.

[0149] The adjustment of the opening degree of the first and second regulating valves, based on the distance and flow rate corresponding to the first and second regulating valves, the influence of changes in these distances and flow rates, and the outlet temperature of the liquid cooling system, includes:

[0150] Based on the distance, pipeline conditions, and flow rate corresponding to the first regulating valve, the distance, pipeline conditions, and flow rate corresponding to the second regulating valve, the impact of changes, and the outlet temperature of the liquid cooling system, adjust the opening degree of the first regulating valve and the second regulating valve.

[0151] As can be seen, in the process of controlling the first and second regulating valves, if the change in the outlet temperature of the liquid cooling system is significantly affected by the current heat exchange on the coolant, the opening degree of the first and second regulating valves is adjusted according to the distance and flow rate corresponding to the first and second regulating valves, the change in the flow rate, and the outlet temperature of the liquid cooling system. This achieves precise control of the flow rate from the first and second regulating valves, thereby improving the heat exchange accuracy of the heat exchanger and thus improving the control accuracy of the outlet temperature of the liquid cooling system. Furthermore, by incorporating parameters such as the pipe material, curvature, and orifice diameter between the first and second regulating valves and the heat exchanger into the determination of the total flow rate flowing to the heat exchanger per unit time, the accuracy of the total flow rate determination can be improved. Simultaneously, by incorporating parameters such as the pipe material, curvature, and orifice diameter between the first and second regulating valves and the heat exchanger into the opening degree adjustment, the accuracy of the opening degree adjustment of the two regulating valves can be improved, which in turn helps to improve the control accuracy of the outlet temperature of the liquid cooling system.

[0152] Example 3

[0153] Please see Figure 3 , Figure 3 This is a schematic diagram of the structure of an intelligent temperature control device for a liquid cooling system disclosed in an embodiment of the present invention. The intelligent control device includes one or more of the following: an intelligent control system, an intelligent control server, intelligent control equipment, and the liquid cooling system itself. The intelligent control server includes a local server or a cloud server. Figure 3 As shown, the device includes:

[0154] Acquisition module 301 acquires load data of the heat exchanger in the liquid cooling system;

[0155] The determination module 302 is used to determine the load change of the heat exchanger based on the collected load data;

[0156] The determination module 302 is also used to determine the control mode of the regulating valve that matches the load change of the heat exchanger based on the load change of the heat exchanger;

[0157] Control module 303 is used to control the first and second regulating valves of the liquid cooling system to perform matching temperature regulation operations according to the determined regulating valve control mode;

[0158] In this embodiment of the invention, when the load change of the heat exchanger is used to indicate that the degree of load change of the heat exchanger is less than or equal to a preset change threshold, the regulating valve control mode that matches the load change of the heat exchanger is the first regulating valve control mode; when the load change of the heat exchanger is used to indicate that the degree of load change of the heat exchanger is greater than the preset change threshold, the regulating valve control mode that matches the load change of the heat exchanger is the second regulating valve control mode.

[0159] It is evident that implementation Figure 3 The intelligent control device for the liquid cooling system temperature described herein can reduce the resistance of the liquid cooling system by controlling the dual regulating valves. Even with small flow rate adjustments, it can achieve precise regulation of the outlet temperature of the liquid cooling system, while improving the smooth operation of other units in the same ring network. Furthermore, even if there is a sudden change in load, the dual regulating valves can control the outlet temperature of the liquid cooling system to change slowly, shortening the time it takes for the outlet temperature to stabilize.

[0160] In an optional embodiment, when the control mode of the regulating valve is the first regulating valve control mode, the control module 303 controls the first regulating valve and the second regulating valve of the liquid cooling system to perform matching temperature regulation operations according to the determined regulating valve control mode. The specific methods include:

[0161] Control the first regulating valve to be fully closed and the second regulating valve to be fully open, and obtain the first outlet temperature of the liquid cooling system;

[0162] Determine whether the first outlet temperature of the liquid cooling system is greater than or equal to the preset temperature. When it is determined that the first outlet temperature of the liquid cooling system is greater than or equal to the preset temperature, control the second regulating valve to remain fully open and control the first regulating valve to gradually open until the first regulating valve is fully open.

[0163] The system collects the second outlet temperature of the liquid cooling system when the first regulating valve is fully open, and determines whether the second outlet temperature of the liquid cooling system is greater than or equal to the preset temperature. When the determination result is yes, the system controls the first regulating valve to be fully open and controls the second regulating valve to gradually close.

[0164] During the process of gradually closing the second regulating valve, the third outlet temperature of the liquid cooling system is collected, and the first and second regulating valves are controlled according to the third outlet temperature of the liquid cooling system.

[0165] During the process of controlling the first and second regulating valves based on the third outlet temperature of the liquid cooling system, the fourth outlet temperature of the liquid cooling system is collected. When the fourth outlet temperature of the liquid cooling system is less than or equal to the preset temperature and the second regulating valve is in the fully open state, the second regulating valve is controlled to remain fully open, and the first regulating valve is controlled to gradually close.

[0166] It is evident that implementation Figure 3 The intelligent temperature control device for the liquid cooling system described can also precisely control the dual regulating valves based on the comparison between the outlet temperature of the liquid cooling system and the set temperature when the load change of the heat exchanger of the liquid cooling system is small. During the control process, the outlet temperature of the liquid cooling system is still monitored in real time, and the dual regulating valves are controlled based on the real-time monitoring results, thereby achieving precise flow regulation and thus precise control of the outlet temperature.

[0167] In another optional embodiment, the control module 303 controls the first regulating valve and the second regulating valve according to the third outlet temperature of the liquid cooling system in the following ways:

[0168] When the temperature at the third outlet of the liquid cooling system is lower than the preset temperature, the first regulating valve is controlled to maintain its current state and the second regulating valve is controlled to gradually open.

[0169] When the third outlet temperature of the liquid cooling system equals the preset temperature, control the first regulating valve and the second regulating valve to maintain the current state.

[0170] When the temperature at the third outlet of the liquid cooling system exceeds the preset temperature, the second regulating valve is gradually closed.

[0171] It is evident that implementation Figure 3 The intelligent temperature control device for the liquid cooling system described can also finely control the dual regulating valves by comparing the monitored outlet temperature with the set temperature during the adjustment process, thereby further improving the accuracy of flow regulation, improving the accuracy and efficiency of heat exchanger contact with flow, and thus improving the heat exchange efficiency and accuracy of the heat exchanger.

[0172] In another optional embodiment, when the regulating valve control mode is the second regulating valve control mode, the specific method by which the control module 303 controls the first regulating valve and the second regulating valve of the liquid cooling system to perform matching temperature regulation operations according to the determined regulating valve control mode includes:

[0173] Collect the spatial temperature of the space where the liquid cooling system is located, and compare the change value of the spatial temperature of the space where the liquid cooling system is located with the preset spatial change threshold to obtain the comparison result;

[0174] When the comparison result indicates that the change in the space temperature of the liquid cooling system is greater than or equal to the preset space change threshold, the fifth outlet temperature of the liquid cooling system is collected.

[0175] Determine whether the fifth outlet temperature of the liquid cooling system is greater than or equal to the preset temperature. If the determination result is yes, control the first regulating valve to gradually open and control the second regulating valve to gradually close until the second regulating valve is completely closed.

[0176] The first regulating valve is controlled to operate based on the space temperature of the liquid cooling system and the fifth outlet temperature of the liquid cooling system, while the second regulating valve is kept closed. The sixth outlet temperature of the liquid cooling system is continuously collected, and when the sixth outlet temperature of the liquid cooling system is lower than the preset temperature, the first regulating valve is controlled to gradually close, while the second regulating valve is controlled to gradually open until the second regulating valve is fully open.

[0177] The method may also include the following steps:

[0178] When the second regulating valve is fully open, the space temperature of the liquid cooling system is collected, and the second regulating valve control mode is exited when the change value of the space temperature of the liquid cooling system is greater than or equal to the preset space temperature stability value.

[0179] It is evident that implementation Figure 3 The intelligent temperature control device for the liquid cooling system described can also precisely control the dual regulating valves in a corresponding manner when the load of the heat exchanger of the liquid cooling system changes significantly, based on the comparison between the outlet temperature of the liquid cooling system and the set temperature. During the control process, the outlet temperature of the liquid cooling system is still monitored in real time, and the dual regulating valves are controlled in turn based on the real-time monitoring results, thereby achieving precise flow regulation and thus precise control of the outlet temperature.

[0180] In yet another alternative embodiment, such as Figure 4 As shown, the device also includes:

[0181] The first judgment module 304 is used to determine whether the collected seventh outlet temperature of the liquid cooling system is less than or equal to the preset dew point temperature during the process of controlling the first and second regulating valves based on the first regulating valve control mode or the second regulating valve control mode.

[0182] The control module 303 is also used to control the first regulating valve to gradually close and the second regulating valve to gradually open when the judgment result is yes;

[0183] The monitoring module 305 is used to monitor the outlet temperature of the liquid cooling system in real time during the process of controlling the first regulating valve and the second regulating valve, and obtain the first monitoring result.

[0184] The control module 303 is also used to control the first regulating valve and the second regulating valve to maintain the current state when the first monitoring result indicates that the real-time monitored outlet temperature of the liquid cooling system is equal to the preset dew point temperature.

[0185] The monitoring module 305 is also used to continue to monitor the outlet temperature of the liquid cooling system in real time and obtain a second monitoring result;

[0186] The control module 303 is further configured to, when the second monitoring result indicates that the outlet temperature of the liquid cooling system monitored in real time is greater than the preset dew point temperature, control the first regulating valve to gradually open and control the second regulating valve to remain fully open.

[0187] It is evident that implementation Figure 4 The intelligent temperature control device for the liquid cooling system described can also control the two regulating valves to act simultaneously if the outlet temperature of the liquid cooling system is higher than the set dew point temperature during the process of regulating the outlet temperature of the liquid cooling system by controlling the dual regulating valves. This improves the accuracy and timeliness of flow regulation, thereby reducing the occurrence of water droplets on the server equipment, reducing the occurrence of damage to the server equipment, and extending the service life of the equipment.

[0188] In yet another alternative embodiment, such as Figure 4 As shown, the device also includes:

[0189] The second judgment module 306 is used to determine whether there is a faulty control valve during the process of controlling the first control valve and the second control valve based on the first control valve control mode or the second control valve control mode.

[0190] The determination module 302 is also used to determine the type of the faulty control valve when the judgment result is yes, and to determine the fault control mode that matches the type of the faulty control valve based on the type of the faulty control valve.

[0191] The control module 303 is also used to control the corresponding control valve according to the fault control mode that matches the type of the fault control valve.

[0192] It is evident that implementation Figure 4 The intelligent temperature control device for the liquid cooling system described can also precisely control the other regulating valve if a malfunction occurs during the control of the dual regulating valves, thereby ensuring the stability of the liquid cooling system's outlet temperature and ensuring that the outlet temperature of the liquid cooling system is as close as possible to the required temperature.

[0193] In this optional embodiment, the control module 303 controls the corresponding regulating valve in the following specific ways according to the fault control mode that matches the type of the fault regulating valve:

[0194] When the fault control valve is the first control valve, the first control valve is controlled to be fully open, and when the outlet temperature of the liquid cooling system is less than the preset temperature, the second control valve is controlled to gradually open; when the outlet temperature of the liquid cooling system is detected to be equal to the preset temperature, the second control valve is controlled to maintain the current state; when the outlet temperature of the liquid cooling system is detected to be greater than the preset temperature, the second control valve is controlled to gradually close.

[0195] When the fault control valve is the second control valve, the second control valve is controlled to be closed, and when the outlet temperature of the liquid cooling system is less than the preset temperature, the first control valve is controlled to gradually close; when the outlet temperature of the liquid cooling system is detected to be equal to the preset temperature, the first control valve is controlled to maintain its current state; when the outlet temperature of the liquid cooling system is detected to be greater than the preset temperature, the first control valve is controlled to gradually open.

[0196] It is evident that implementation Figure 4 The intelligent temperature control device for the liquid cooling system described can also precisely control another regulating valve based on the failure of the regulating valve, thus ensuring a stable output temperature of the liquid cooling system even when a regulating valve fails.
