Description

Technical Field

[0001] The present invention relates to the field of liquid cooling system control, and more particularly, to a coordinated control method and device for a liquid cooling system. Background Art

[0002] Liquid cooling systems are one of the primary methods for temperature control in data centers. They are divided into a primary side, a secondary side, and a user side. The primary side connects to the external environment and provides cooling, exchanging heat with the secondary side at a heat exchanger. The secondary and user sides exchange heat with the data center, using heat exchangers to transfer heat collected by the data center. This allows the data center to be temperature-regulated by the cooling provided by the primary side, ensuring an optimal temperature environment for data center use. The operation of a liquid cooling system is interconnected with the external environment, the primary side, the secondary side, and the user side. Ensuring energy-efficient and stable operation of liquid cooling systems is a key research focus in this field.

[0003] In existing technology, data center liquid cooling systems typically control cooling capacity by controlling the primary side's operating pressure differential, while also using the secondary side's operating pressure and temperature differential to provide feedback control of cooling capacity. These systems, with their respective operating logics, ensure the stability of the entire liquid cooling system. However, the following issues remain: The primary and secondary sides are controlled independently, and the primary side is not linked to the ambient temperature. This can lead to situations where both the primary and secondary sides are operating in an unoptimal state, potentially affecting the entire liquid cooling system. Therefore, improvements to the control methods for liquid cooling systems are necessary. Summary of the Invention

[0004] The present invention aims to overcome at least one defect (shortcoming) of the above-mentioned prior art and provide a collaborative control method and device for a liquid cooling system, which is used to realize collaborative joint control of the external ambient temperature, the primary side, the secondary side, and the user side of the liquid cooling system, so as to ensure energy-saving and stable operation of the liquid cooling system.

[0005] According to a first aspect of the present application, a coordinated control method for a liquid cooling system is provided, wherein the liquid cooling system includes a primary side pipeline, a secondary side pipeline, and a user side pipeline; the method comprises:

[0006] Obtain primary side temperature value, user side temperature value and corresponding user side pressure value in real time;

[0007] Monitor whether the primary side temperature value, the user side temperature value, and the corresponding user side pressure value have reached a steady state, and if so, record the total cooling power of the current liquid cooling system and the current operating parameters of the components;

[0008] Obtaining an external air temperature value of the air cooler in the primary side pipeline;

[0009] Preset a temperature threshold, and obtain target operating parameters of components of the liquid cooling system according to the total cooling power and the current operating parameters of the components, the temperature threshold, and the ambient air temperature;

[0010] The components of the liquid cooling system are adjusted accordingly according to the target operating parameters of the components, so that the liquid cooling system can operate stably and energy-efficiently.

[0011] It is understandable that by obtaining the primary-side temperature value, the user-side temperature value, and the corresponding user-side pressure value in real time, and ensuring that the primary-side temperature value, the user-side temperature value, and the corresponding user-side pressure value reach a steady state before proceeding to the next step, it is possible to ensure that the recorded total cooling power of the liquid cooling system and the current operating parameters of the components are obtained in a stable and reliable state, and to avoid data inaccuracy or misjudgment caused by fluctuations or transient changes in the liquid cooling system parameters, thereby improving the accuracy and effectiveness of subsequent component adjustment and control based on the total cooling power and the current operating parameters of the components, ensuring that the liquid cooling system can operate stably and efficiently and achieve energy saving goals. According to the relationship between the outside air temperature value and the temperature threshold, the command for adjusting the air cooler gear / circulation pump gear or the electric two-way valve gear is obtained, which can accurately obtain the outside temperature environment characteristics. Based on the outside temperature characteristics, the parameters of different components of the liquid cooling system are flexibly adjusted to obtain the optimal component target parameters, so that the liquid cooling system can coordinately control different components on the primary and secondary sides according to the outside temperature characteristics, thereby achieving the effect of coordinated control of each side of the liquid cooling system and realizing energy-saving optimization and stable operation of the liquid cooling system.

[0012] Optionally, the operating parameters respectively include the air cooler gear position set in the primary side pipeline, the electric two-way valve opening set in the primary side pipeline and the circulating pump gear position set in the secondary side pipeline. The air cooler is used to exchange heat with the primary side pipeline, the electric two-way valve is used to control the refrigerant flow rate in the primary side pipeline, and the circulating pump is used to control the refrigerant flow rate in the secondary side pipeline.

[0013] It is understandable that by adjusting the operating parameters of the components in the liquid cooling system, specifically adjusting the parameters of the key components on different sides, the working conditions of different sides can be accurately adjusted and the operating conditions of different sides can be quickly grasped. Among them, adjusting the air cooler gear on the primary side can fully consider the impact of the external temperature on the primary side cooling efficiency; adjusting the circulating pump gear on the secondary side to adjust the refrigerant flow rate in the secondary side can fully consider the impact of the primary side on the heat exchange efficiency of the secondary side; adjusting the electric two-way valve gear on the primary side to adjust the refrigerant flow rate in the primary side can fully consider the impact of the external temperature on the primary side cooling efficiency. The above processing can realize the refined and intelligent management of the liquid cooling system, which not only improves the energy efficiency and stability of the liquid cooling system, but also reduces the operating cost and maintenance difficulty, enhances the system's adaptability to complex working conditions, and ensures that the liquid cooling system can operate efficiently and stably in different environments.

[0014] Optionally, obtaining target operating parameters of components of the liquid cooling system according to the total cooling power, the current operating parameters of the components, the temperature threshold, and the ambient air temperature value includes:

[0015] determining whether the outside air temperature is greater than or equal to the temperature threshold, and if so, performing a first adjustment on the air cooler gear and / or the circulating pump gear according to the total cooling power and the current operating parameters of the components, and obtaining the target operating parameters of the components according to the first adjustment;

[0016] If not, a second adjustment is performed on the opening of the electric two-way valve according to the total cooling power and the current operating parameters of the component, and the target operating parameters of the component are obtained according to the second adjustment.

[0017] It is understandable that by judging the relationship between the outside air temperature and the temperature threshold, the component adjustment strategy is dynamically selected, including the first adjustment and the second adjustment, so as to obtain the target operating parameters of the components of the liquid cooling system under different external environments. The liquid cooling system is adjusted according to the target operating parameters of the components, which can make the cooling power of the liquid cooling system better and the operation more energy-saving and stable.

[0018] Optionally, performing a first adjustment on the air cooler gear according to the total cooling power and the current operating parameters of the components includes:

[0019] obtaining a current gear position of the air cooler according to the current operating parameters of the component;

[0020] Obtaining a maximum threshold value of the air cooler gear position;

[0021] gradually increasing the current gear of the air cooler according to the first gear value at the same interval, and correspondingly recording the cooling power of the liquid cooling system and the current operating parameters of the corresponding components at each current gear of the air cooler after the gear is increased, and stopping increasing the gear of the current gear of the air cooler when the current gear of the air cooler after the gear is increased is equal to the maximum threshold value of the air cooler gear;

[0022] The minimum value of the total cooling power and the cooling power of the liquid cooling system at the current gear of each air cooler after the gear is increased is obtained as the first minimum cooling power, and the current operating parameters of the components corresponding to the first minimum cooling power are used as the first optimal operating parameters.

[0023] It can be understood that by gradually increasing the air cooler gear and recording the corresponding cooling power and current component operating parameters until the air cooler gear increases to the maximum threshold and then stops increasing, the minimum of the total cooling power and the cooling power after gear adjustment is finally selected as the first minimum cooling power, and the corresponding current component operating parameters are used as the optimal target, thus achieving refined adjustment of the air cooler gear. This process ensures that while meeting cooling needs, it also ensures that the liquid cooling system operates at the lowest energy consumption, optimizes energy efficiency, avoids energy waste or equipment overload caused by excessive gear adjustment, and improves the stability and economy of the liquid cooling system.

[0024] Optionally, performing a first adjustment on the gear position of the circulating pump according to the total refrigeration power and the current operating parameters of the components includes:

[0025] Obtaining the current gear position of the circulating pump according to the current operating parameters of the component;

[0026] Obtaining the maximum threshold of the circulating pump gear position;

[0027] gradually increasing the current gear of the circulating pump according to second gear values ​​at the same interval, and correspondingly recording the cooling power of the liquid cooling system and the current operating parameters of the corresponding components at each current gear of the circulating pump after the gear increase, and stopping increasing the current gear of the circulating pump when the current gear of the circulating pump after the gear increase is equal to the maximum threshold value of the circulating pump gear;

[0028] The minimum value of the total cooling power and the cooling power of the liquid cooling system at the current gear of each circulating pump after the gear is increased is obtained as the second minimum cooling power, and the current operating parameters of the components corresponding to the second minimum cooling power are used as the second optimal operating parameters.

[0029] It can be understood that by gradually increasing the circulating pump gear and recording the corresponding cooling power and current component operating parameters until the circulating pump gear reaches the maximum threshold and stops increasing, the minimum of the total cooling power and the cooling power after gear adjustment is finally selected as the first minimum cooling power, and the corresponding current component operating parameters are used as the optimal target, thus achieving refined adjustment of the circulating pump gear. This process ensures that while meeting the cooling demand, it also ensures that the liquid cooling system operates at the lowest energy consumption, optimizes energy efficiency, avoids energy waste or equipment overload caused by excessive gear adjustment, and improves the stability and economy of the liquid cooling system.

[0030] Optionally, obtaining the component target operating parameter according to the first adjustment includes:

[0031] Using the first optimal operating parameter as the component target operating parameter;

[0032] and / or,

[0033] using the second optimal operating parameter as the component target operating parameter;

[0034] and / or,

[0035] Determine whether the first minimum cooling power is less than or equal to the second minimum cooling power; if so, use the first optimal operating parameter as the component target operating parameter; otherwise, use the second optimal operating parameter as the component target operating parameter.

[0036] It's easy to see how this approach maximizes the energy efficiency of the liquid cooling system by comparing the first minimum cooling power achieved after adjusting the air cooler's gear position with the second minimum cooling power achieved after adjusting the circulating pump's gear position, and selecting the more optimal component operating parameters corresponding to the lower cooling power as the target value. This process ensures the system operates at the lowest energy consumption while meeting cooling requirements, while avoiding energy waste or equipment overload caused by adjusting a single parameter, thereby improving the overall economy and stability of the system.

[0037] Optionally, performing a second adjustment on the opening of the electric two-way valve based on the total cooling power and the current operating parameters of the component, and obtaining the target operating parameters of the component according to the second adjustment, includes:

[0038] Obtaining the current opening of the electric two-way valve according to the current operating parameters of the component;

[0039] Obtaining a maximum threshold value of the electric two-way valve opening;

[0040] gradually increasing the current opening of the electric two-way valve according to opening values ​​at the same interval, and correspondingly recording the cooling power of the liquid cooling system and the current operating parameters of the corresponding components at each current opening of the electric two-way valve after the opening is increased, and stopping increasing the current opening of the electric two-way valve when the current opening of the electric two-way valve after the opening is increased equals the maximum threshold value of the electric two-way valve opening;

[0041] The minimum value among the total cooling power and the cooling power of the liquid cooling system at the current opening of each electric two-way valve after the gear is increased is obtained as the third minimum cooling power, and the current operating parameters of the components corresponding to the third minimum cooling power are used as the target operating parameters of the components.

[0042] It can be understood that by gradually increasing the electric two-way valve opening and recording the corresponding cooling power and current component operating parameters until the electric two-way valve opening reaches the maximum threshold and stops increasing, the minimum of the total cooling power and the cooling power after gear adjustment is finally selected as the first minimum cooling power, and the corresponding current component operating parameters are used as the optimal target, thus achieving refined adjustment of the electric two-way valve opening. This process ensures that while meeting cooling needs, it also ensures that the liquid cooling system operates at the lowest energy consumption, optimizes energy efficiency, avoids energy waste or equipment overload caused by excessive gear adjustment, and improves the stability and economy of the liquid cooling system.

[0043] Optionally, the user-side temperature value includes a first temperature value and a second temperature value, the first temperature value is obtained by a first temperature sensor provided at a first output port of the user-side pipeline, and the second temperature value is obtained by a second temperature sensor provided at a first input port of the user-side pipeline;

[0044] The user-side pressure value includes a first pressure value and a second pressure value, the first pressure value is obtained by a first pressure sensor provided at a first output port of the user-side pipeline, and the second pressure value is obtained by a second pressure sensor provided at a first input port of the user-side pipeline;

[0045] The first temperature value corresponds to the first pressure value, the second temperature value corresponds to the second pressure value, the first output port is the refrigerant output port of the user load in the user side pipeline, and the first input port is the refrigerant input port of the user load in the user side pipeline.

[0046] As can be understood, by installing temperature sensors and pressure sensors at the refrigerant inlet and outlet of the user-side piping, respectively, the real-time temperature and pressure of the refrigerant input and output of the user load are acquired, ensuring the consistency and accuracy of the user-side temperature and pressure data. This also comprehensively reflects the refrigerant input and output status of the user load, providing a reliable data foundation for steady-state monitoring, parameter optimization, and energy-saving control of the liquid cooling system, thereby improving the system's operational stability and energy efficiency management accuracy.

[0047] Optionally, the primary side temperature value includes a third temperature value and a fourth temperature value, the third temperature value is obtained by a third temperature sensor provided at a second output port of the primary side pipeline, and the fourth temperature value is obtained by a fourth temperature sensor provided at a second input port of the primary side pipeline; wherein the second output port is a refrigerant output port of an air cooler in the primary side pipeline, and the second input port is a refrigerant input port of the air cooler in the primary side pipeline;

[0048] and / or,

[0049] The outside air temperature value is obtained by a fifth temperature sensor disposed in the air cooler.

[0050] It is understandable that by setting temperature sensors at the refrigerant inlet and outlet of the air cooler respectively, the refrigerant temperature at the input and output of the air cooler in the primary side pipeline is monitored in real time, and the fifth temperature sensor inside the air cooler is used to monitor the outside air temperature value, which fully reflects the heat exchange status and environmental impact of the air cooler, and can provide accurate temperature data support for steady-state judgment, parameter optimization and energy-saving control of the liquid cooling system, ensuring the maximization of the heat exchange efficiency of the air cooler, while improving the system's adaptability to environmental changes and operational stability.

[0051] According to a second aspect of the present application, a coordinated control device for a liquid cooling system is provided, the device comprising:

[0052] The pipeline status acquisition module is used to obtain the primary side temperature value, the user side temperature value and the corresponding user side pressure value in real time;

[0053] a monitoring module, configured to monitor whether the primary side temperature value, the user side temperature value, and the corresponding user side pressure value have reached a steady state, and if so, record the total cooling power of the liquid cooling system and the current operating parameters of the components;

[0054] An external temperature acquisition module is used to acquire the external air temperature value of the air cooler in the primary side pipeline;

[0055] a target operating parameter acquisition module, configured to preset a temperature threshold value and acquire target operating parameters of components of the liquid cooling system according to the total cooling power and the current operating parameters of the components, the temperature threshold value, and the ambient air temperature value;

[0056] The adjustment module is used to adjust the components of the liquid cooling system according to the target operating parameters of the components, so that the liquid cooling system can operate stably and energy-efficiently.

[0057] Based on any one of the above aspects, the embodiment of the present application provides a collaborative control method and device for a liquid cooling system, which obtains the primary side temperature value and the user side temperature value and the corresponding user side pressure value in real time; monitors whether the primary side temperature value, the user side temperature value and the corresponding user side pressure value have reached a steady state, and if so, records the total cooling power of the current liquid cooling system and the current operating parameters of the components; obtains the outside air temperature value of the air cooler in the primary side pipeline; presets a temperature threshold, and obtains the target operating parameters of the components of the liquid cooling system based on the total cooling power and the current operating parameters of the components, the temperature threshold and the outside air temperature value; adjusts the components of the liquid cooling system accordingly according to the target operating parameters of the components, so that the liquid cooling system can operate stably and energy-efficiently. The present application can achieve the following benefits:

[0058] The operating parameters of each component in the liquid cooling system can be transmitted quickly through the collaborative control method and collaborative control device of the present application, realizing the collaborative control of the operating parameters of multiple components, improving the control fault tolerance of the liquid cooling system, and making the control of the liquid cooling system more stable, energy-saving and reliable; ensuring that the liquid cooling system is in the optimal state for all operating conditions, ensuring that the liquid cooling system operates at the optimal cooling capacity, and improving the energy efficiency and performance reliability of the liquid cooling system; and obtaining the optimal cooling efficiency in the liquid cooling system through comparison, and then using the component operating parameters corresponding to the optimal cooling efficiency to adjust the components of the liquid cooling system, so that the liquid cooling system is in the optimal state for all operating conditions.

DETAILED DESCRIPTION

[0068] The figures in this application are for illustrative purposes only and are not to be construed as limiting the present application. To better illustrate the following embodiments, some components in the figures may be omitted, enlarged, or reduced in size, and do not represent actual product dimensions. Those skilled in the art will appreciate that some well-known structures and their descriptions may be omitted from the figures.

[0069] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0070] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequential order. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in a sequence other than those illustrated or described herein. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0071] In the prior art, the liquid cooling system of a data center usually controls the cooling capacity by controlling the pressure difference used on the primary side, and at the same time controls the cooling capacity by feedback through the pressure difference and temperature difference used on the secondary side, and ensures the stability of the entire liquid cooling system through their respective operating logics. However, the different sides of the liquid cooling system only adjust the energy consumption of their own side based on the monitoring data of their own side, and do not consider the operating data of the adjacent side or the entire liquid cooling system running on this side, and cannot ensure that the overall operating state of the entire liquid cooling system is in the best state. It is understandable that the operation of the liquid cooling system does not rely solely on the work of one side for liquid cooling, and the heat exchange work between different sides is always closely related. Therefore, it is necessary to consider the impact of the external environment on the liquid cooling system, and to coordinately couple and control the components on each side of the liquid cooling system so that the overall energy consumption of the liquid cooling system can be optimized and stable and energy-saving operation can be achieved. Therefore, this application makes necessary improvements to the collaborative control method of the liquid cooling system.

[0072] This embodiment provides a technical solution that can solve the above-mentioned problem. The specific implementation methods of this application are described in detail below with reference to the accompanying drawings.

[0073] For example, Figure 1 , which is an example diagram of the system structure of a liquid cooling system provided in an embodiment of the present application.

[0074] The liquid cooling system includes a primary side pipeline, a secondary side pipeline and a user side pipeline.

[0075] The primary-side pipeline may include a third temperature sensor T3, a fourth temperature sensor T4, and a fifth temperature sensor T5, as well as an air cooler 01, an electric two-way valve 02, and a heat exchanger 03 connected by pipes. The primary-side refrigerant in the primary-side pipeline circulates sequentially through the air cooler 01, the electric two-way valve 02, and the heat exchanger 03. The fifth temperature sensor T5 is located in the air cooler 01 and measures the temperature of the outside air entering the air cooler 01. The third temperature sensor T3 is located at the second output port, which is the refrigerant output port of the air cooler 01 in the primary-side pipeline. The fourth temperature sensor T4 is located at the second input port, which is the refrigerant input port of the air cooler 01 in the primary-side pipeline.

[0076] Among them, the air cooler 01 is the place where the primary side refrigerant exchanges heat with the outside air. The amount of outside air blown in can be adjusted by adjusting the gear of the air cooler 01, thereby affecting the heat exchange effect between the outside air and the primary side refrigerant; the fifth temperature sensor T5 is used to monitor the temperature of the outside air in real time; the third temperature sensor T3 is used to obtain the temperature of the primary side refrigerant after heat exchange with the outside air; the electric two-way valve 02 adjusts the flow rate of the primary side refrigerant by adjusting its opening, thereby affecting the heat exchange effect between the outside air and the primary side refrigerant in the air cooler 01, and affecting the heat exchange effect between the primary side refrigerant and the secondary side refrigerant in the heat exchanger 03; the heat exchanger 03 is the place where the primary side refrigerant and the secondary side refrigerant exchange heat; the fourth temperature sensor T4 is used to obtain the temperature of the primary side refrigerant before heat exchange with the outside air.

[0077] The secondary-side pipeline includes a heat exchanger 03 and a circulating pump 04 connected by pipes. The secondary-side refrigerant flows through the heat exchanger 03 and circulating pump 04, then enters the user-side pipeline. After exiting the user-side pipeline, it re-enters the heat exchanger 03 in the secondary-side pipeline. Heat exchanger 03 is shared by both the primary and secondary pipelines.

[0078] The circulating pump 04 adjusts the flow rate of the secondary refrigerant by adjusting its gear position, thereby affecting the heat exchange effect between the primary refrigerant and the secondary refrigerant in the heat exchanger 03.

[0079] The user-side pipeline may include a user load 05, a first pressure sensor P1, a first temperature sensor T1, a second temperature sensor T2, and a second pressure sensor P2. The user-side pipeline and the secondary-side pipeline are connected to form a loop; the secondary-side refrigerant entering the user-side pipeline enters the secondary-side pipeline via the user load 05, passes through the heat exchanger 03 and the circulating pump 04, and then returns to the user load 05; the first pressure sensor P1 and the first temperature sensor T1 are respectively arranged at the first output port, which is the refrigerant output port of the user load 05 in the user-side pipeline; the second temperature sensor T2 and the second pressure sensor P2 are respectively arranged at the first input port, which is the refrigerant input port of the user load 05 in the user-side pipeline;

[0080] The user load 05 is a place where the secondary refrigerant exchanges heat with the user load. The user load may include equipment that the user requires liquid cooling, which may be a data center in this embodiment. The first pressure sensor P1 is used to obtain the pressure of the secondary refrigerant after heat exchange with the user load 05. The first temperature sensor T1 is used to obtain the temperature of the secondary refrigerant after heat exchange with the user load 05. The second temperature sensor T2 is used to obtain the temperature of the secondary refrigerant before heat exchange with the user load 05. The second pressure sensor P2 is used to obtain the pressure of the secondary refrigerant before heat exchange with the user load 05.

[0081] like Figure 2 As shown, this embodiment provides a coordinated control method for a liquid cooling system, wherein the liquid cooling system includes a primary side pipeline, a secondary side pipeline, and a user side pipeline. The method can be subdivided into the following steps:

[0082] S100, obtaining the primary side temperature value, the user side temperature value and the corresponding user side pressure value in real time;

[0083] Specifically, the user-side temperature value includes a first temperature value and a second temperature value, the first temperature value is obtained by a first temperature sensor provided at a first output port of the user-side pipeline, and the second temperature value is obtained by a second temperature sensor provided at a first input port of the user-side pipeline;

[0084] The user-side pressure value includes a first pressure value and a second pressure value, the first pressure value is obtained by a first pressure sensor provided at a first output port of the user-side pipeline, and the second pressure value is obtained by a second pressure sensor provided at a first input port of the user-side pipeline;

[0085] The first temperature value corresponds to the first pressure value, the second temperature value corresponds to the second pressure value, the first output port is the refrigerant output port of the user load in the user side pipeline, and the first input port is the refrigerant input port of the user load in the user side pipeline.

[0086] In this embodiment, the first temperature value and the corresponding first pressure value, as well as the second temperature value and the corresponding second pressure value, are all user-side data. Specifically, the first temperature value and the corresponding first pressure value represent the temperature and pressure of the secondary-side refrigerant after heat exchange with the user load, and the second temperature value and the corresponding second pressure value represent the temperature and pressure of the secondary-side refrigerant before heat exchange with the user load. By detecting the first temperature value and the corresponding first pressure value, and the second temperature value and the corresponding second pressure value, the state of the liquid cooling system user side before and after heat exchange with the user load can be monitored in real time, providing a data basis for subsequently determining the steady state of the liquid cooling system.

[0087] Specifically, the primary side temperature value includes a third temperature value and a fourth temperature value, the third temperature value is obtained by a third temperature sensor arranged at the second output port of the primary side pipeline, and the fourth temperature value is obtained by a fourth temperature sensor arranged at the second input port of the primary side pipeline; wherein the second output port is the refrigerant output port of the air cooler in the primary side pipeline, and the second input port is the refrigerant input port of the air cooler in the primary side pipeline.

[0088] In this embodiment, the third and fourth temperature values ​​are both primary-side data. Specifically, the third temperature value represents the temperature and pressure of the primary-side refrigerant after heat exchange with the outside air, and the fourth temperature value represents the temperature and pressure of the primary-side refrigerant after heat exchange with the user load. By monitoring the third and fourth temperature values, the state of the liquid cooling system's primary side before and after heat exchange with the outside air can be monitored in real time, providing a data basis for subsequent determination of the liquid cooling system's steady state.

[0089] S200, monitoring whether the primary-side temperature value, the user-side temperature value, and the corresponding user-side pressure value have reached a steady state, and if so, recording the total cooling power of the current liquid cooling system and the current operating parameters of the components;

[0090] In this embodiment, subsequent operations can only be continued after the primary-side temperature value, the user-side temperature value, and the corresponding user-side pressure value reach a steady state. It is understood that steady state refers to when the relevant system parameters remain relatively stable for a certain period of time during system operation and no longer experience significant fluctuations or changes.

[0091] In this embodiment, the total cooling power refers to the total cooling power required for the entire liquid cooling system. A lower cooling power indicates lower cooling energy consumption and better operating conditions. Therefore, the ultimate goal of this embodiment is to minimize the cooling power of the liquid cooling system while ensuring smooth cooling.

[0092] Preferably, in this embodiment, if the primary side temperature value, the user side temperature value and the corresponding user side pressure value reach a steady state, it indicates that the liquid cooling system is also in a steady-state equilibrium operating state. In this state, the optimal operating state of the liquid cooling system is obtained to avoid inaccurate data or misjudgment caused by fluctuations or transient changes in the operating parameters of related components of the liquid cooling system, thereby improving the accuracy and efficiency of subsequent acquisition of the optimal state of the liquid cooling system based on the operating parameters of related components.

[0093] Specifically, the operating parameters include the air cooler gear position set in the primary side pipeline, the electric two-way valve opening set in the primary side pipeline and the circulating pump gear position set in the secondary side pipeline. The air cooler is used to exchange heat in the primary side pipeline, the electric two-way valve is used to control the refrigerant flow rate in the primary side pipeline, and the circulating pump is used to control the refrigerant flow rate in the secondary side pipeline.

[0094] In this embodiment, the factors affecting the heat exchange effect between the outside air and the primary refrigerant in the air cooler include the volume of the outside air blown in and the flow rate of the primary refrigerant. In principle, the greater the volume of the outside air blown in, the better the heat exchange effect with the primary refrigerant. However, increasing the volume of the outside air blown in requires increasing the gear of the air cooler, which means that more electricity is consumed by the liquid cooling system, thereby increasing the cooling power of the liquid cooling system and increasing the overall energy consumption of the liquid cooling system. The flow rate of the primary refrigerant should not be too large or too small. If the flow rate of the primary refrigerant is too large, the heat exchange contact time between the primary refrigerant and the outside air is reduced, which may cause the primary refrigerant to flow out of the air cooler without achieving the heat exchange effect. Although a small flow rate of the primary refrigerant can increase the heat exchange contact time between the primary refrigerant and the outside air, it can only exchange heat with a small amount of primary refrigerant per unit time, thereby reducing the heat exchange efficiency, resulting in the use of appropriate energy but failing to achieve the heat exchange effect. Therefore, it is crucial to find the balance between the volume of outside air blown in and the flow rate of the primary-side refrigerant to reduce the cooling power of the liquid cooling system.

[0095] In this embodiment, the air cooler gear position is controlled to adjust the volume of outside air blown in. In a preferred embodiment, the higher the air cooler gear position, the greater the volume of outside air blown in, and the greater the energy consumption of the air cooler. Therefore, the air cooler gear position needs to be adjusted to balance the outside air volume and the energy consumption of the air cooler.

[0096] In this embodiment, the flow rate of the primary-side refrigerant can be adjusted by controlling the opening of the electric two-way valve; in a preferred embodiment, the greater the opening of the electric two-way valve, the greater the flow rate of the primary-side refrigerant.

[0097] In this embodiment, the factors affecting the heat exchange effect between the primary refrigerant and the secondary refrigerant in the heat exchanger include the volume of outside air blown in and the flow rate of the primary refrigerant. In principle, the greater the volume of outside air blown in, the better the heat exchange effect with the primary refrigerant. However, increasing the volume of outside air blown in requires increasing the gear of the air cooler, which means that more electricity is consumed by the liquid cooling system, thereby increasing the cooling power of the liquid cooling system and increasing the overall energy consumption of the liquid cooling system. The flow rate of the primary refrigerant should not be too large or too small. If the flow rate of the primary refrigerant is too large, the heat exchange contact time between the primary refrigerant and the outside air is reduced, which may cause the primary refrigerant to flow out of the air cooler before achieving the heat exchange effect. Although a small flow rate of the primary refrigerant can increase the heat exchange contact time between the primary refrigerant and the outside air, it can only exchange heat with a small amount of primary refrigerant per unit time, thereby reducing the heat exchange efficiency, resulting in the use of appropriate energy but failing to achieve the heat exchange effect. Therefore, it is crucial to find the balance between the volume of outside air blown in and the flow rate of the primary-side refrigerant to reduce the cooling power of the liquid cooling system.

[0098] In this embodiment, the circulating pump's gear position is controlled to adjust the secondary refrigerant flow rate. In a preferred embodiment, the higher the circulating pump gear position, the greater the secondary refrigerant flow rate and the greater the circulating pump's energy consumption. Therefore, the circulating pump gear position needs to be adjusted based on the heat exchange efficiency between the primary and secondary sides and the circulating pump's energy consumption.

[0100] Specifically, the outside air temperature value is obtained by a fifth temperature sensor disposed in the air cooler.

[0101] In this embodiment, it is necessary to constantly monitor the temperature of the outside air based on the acquired outside air temperature value in the air cooler, so that the control of the liquid cooling system can be adjusted according to the changes in the outside air.

[0102] S400, presetting a temperature threshold, obtaining target operating parameters of components of the liquid cooling system according to the total cooling power, the current operating parameters of the components, the temperature threshold, and the ambient air temperature;

[0103] In this embodiment, the temperature threshold can be set based on the operating characteristics of the liquid cooling system, based on historical control operation experience or after multiple actual control operations, and taking into full consideration the cooling efficiency of the liquid cooling system. This temperature threshold can serve as a critical value for changing the relevant control strategies of the liquid cooling system and can serve as important judgment data for the coordinated control method of the liquid cooling system. Preferably, the temperature threshold can be set to a temperature value within the temperature range of [25°C, 30°C] and can be appropriately adjusted based on the actual situation of the liquid cooling system.

[0104] Specifically, if Figure 3 As shown, step S400 may include the following steps:

[0105] S410: Determine whether the outside air temperature is greater than or equal to the temperature threshold; if so, perform a first adjustment on the air cooler gear and / or the circulating pump gear according to the total cooling power and the current operating parameters of the components, and obtain the target operating parameters of the components according to the first adjustment;

[0106] In this embodiment, if the outside air temperature value is greater than or equal to the temperature threshold, it means that the outside air temperature is relatively high relative to the temperature threshold, and the air cooler gear and / or the circulation pump gear need to be adjusted to find the target operating parameters of the components corresponding to the optimal operating state of the liquid cooling system.

[0107] Specifically, if Figure 4 As shown, performing a first adjustment on the air cooler gear according to the total cooling power and the current operating parameters of the components may include the following steps:

[0108] S4111. Obtaining a current gear position of the air cooler according to the current operating parameters of the component;

[0109] In this embodiment, it is necessary to first obtain the current gear position of the air cooler when the primary side temperature value, the user side temperature value, and the corresponding user side pressure value reach a steady state.

[0110] It is understandable that all adjustment operations in this embodiment are performed after the operation of the primary side and the secondary side user side reaches a steady state, which can avoid inaccurate data or misjudgment caused by fluctuations or transient changes in the liquid cooling system parameters, and ensure that the liquid cooling system can obtain the target operating parameters of the components in a stable state and achieve energy-saving goals.

[0111] S4112, obtaining a maximum threshold value of the air cooler gear position;

[0112] In this embodiment, it is necessary to obtain the maximum threshold of the air cooler gear, which indicates the maximum gear to which the air cooler can be adjusted, thereby facilitating the subsequent traversal of the air cooler from the current gear to the maximum gear and obtaining the corresponding cooling power.

[0113] S4113, gradually increasing the current gear of the air cooler according to the first gear value at the same interval, and correspondingly recording the cooling power of the liquid cooling system and the current operating parameters of the corresponding components at each current gear of the air cooler after the gear is increased, and when the current gear of the air cooler after the gear is increased equals the maximum threshold of the air cooler gear, stopping the gear increase of the current gear of the air cooler;

[0114] In this embodiment, the current gear of the air cooler is gradually increased according to the first gear value at the same interval, and the increase stops when the air cooler gear reaches the maximum threshold of the air cooler gear. Under the premise of ensuring the steady-state operation of the primary, secondary, and user sides of the liquid cooling system, the air cooler gear is traversed to obtain the corresponding cooling power, ensuring that the adjustment operation is performed without affecting the normal operation of the liquid cooling system. Preferably, the first gear value can be 1 and can be appropriately adjusted according to the actual situation of the liquid cooling system.

[0115] S4114. Obtain the minimum value of the total cooling power and the cooling power of the liquid cooling system at the current gear of each air cooler after the gear is increased as the first minimum cooling power, and use the current operating parameters of the components corresponding to the first minimum cooling power as the first optimal operating parameters.

[0116] In this embodiment, the minimum value of the total cooling power and the cooling power of the liquid cooling system at the current gear of each air cooler is obtained as the first minimum cooling power, so that the minimum cooling power of the air cooler in each gear under the steady state of the liquid cooling system can be found, and the current operating parameters of the components corresponding to the first minimum cooling power are used as the first optimal operating parameters. Subsequently, the parameters of various components of the liquid cooling system can be adjusted according to the first optimal operating parameters to ensure that the liquid cooling system operates at the first minimum cooling power.

[0117] Specifically, if Figure 5 As shown, performing a first adjustment on the gear position of the circulating pump according to the total refrigeration power and the current operating parameters of the components may include the following steps:

[0118] S4121. Obtain the current gear position of the circulating pump according to the current operating parameters of the component;

[0119] In this embodiment, all adjustment operations in this embodiment are performed after the operation of the primary side and the secondary side user side reaches a steady state, which can avoid inaccurate data or misjudgment caused by fluctuations or transient changes in the liquid cooling system parameters, and ensure that the liquid cooling system can obtain the target operating parameters of the components in a stable state and achieve energy-saving goals.

[0120] S4122, obtaining the maximum threshold of the circulating pump gear position;

[0121] In this embodiment, it is necessary to obtain the maximum threshold of the circulating pump gear, which indicates the maximum gear to which the circulating pump can be adjusted, thereby facilitating the subsequent traversal of the circulating pump from the current gear to the maximum gear and obtaining the corresponding cooling power.

[0122] S4123, gradually increasing the current gear of the circulating pump according to second gear values ​​at the same interval, and correspondingly recording the cooling power of the liquid cooling system and the current operating parameters of the corresponding components at each current gear of the circulating pump after the gear increase; when the current gear of the circulating pump after the gear increase equals the maximum threshold of the circulating pump gear, stopping increasing the current gear of the circulating pump;

[0123] In this embodiment, the circulating pump's current gear is gradually increased according to a second gear value at equal intervals, and the increase in the circulating pump gear stops when the circulating pump gear reaches a maximum threshold. This allows the circulating pump gear to be cycled through to obtain the corresponding cooling power, while ensuring steady-state operation of the primary, secondary, and user sides of the liquid cooling system. This ensures that the adjustment is performed without affecting the normal operation of the liquid cooling system. Preferably, the second gear value can be 1 and can be adjusted appropriately based on the actual conditions of the liquid cooling system.

[0124] S4124. Obtain the minimum value of the total cooling power and the cooling power of the liquid cooling system at the current gear of each circulating pump after the gear is increased as the second minimum cooling power, and use the current operating parameters of the components corresponding to the second minimum cooling power as the second optimal operating parameters.

[0125] In this embodiment, the minimum value of the total cooling power and the cooling power of the liquid cooling system at the current gear of each circulating pump is obtained as the second minimum cooling power, so that the minimum cooling power of the circulating pump in each gear under the steady state of the liquid cooling system can be found, and the current operating parameters of the components corresponding to the second minimum cooling power are used as the second optimal operating parameters. Subsequently, the parameters of various components of the liquid cooling system can be adjusted according to the second optimal operating parameters to ensure that the liquid cooling system operates at the second minimum cooling power.

[0126] Specifically, obtaining the component target operating parameter according to the first adjustment includes:

[0127] Using the first optimal operating parameter as the component target operating parameter;

[0128] and / or,

[0129] using the second optimal operating parameter as the component target operating parameter;

[0130] and / or,

[0131] Determine whether the first minimum cooling power is less than or equal to the second minimum cooling power; if so, use the first optimal operating parameter as the component target operating parameter; otherwise, use the second optimal operating parameter as the component target operating parameter.

[0132] In this embodiment, if only the gear of the air cooler is adjusted, the first optimal operating parameter can be used as the component target operating parameter to adjust the parameters of each component of the liquid cooling system; if only the gear of the circulating pump is adjusted, the second optimal operating parameter can be used as the component target operating parameter to adjust the parameters of each component of the liquid cooling system; if the gear of the air cooler and the gear of the circulating pump are adjusted at the same time, it is necessary to compare the first minimum cooling power obtained by adjusting the air cooler and the second minimum cooling power obtained by adjusting the circulating pump, and find the minimum value between the first minimum cooling power and the second minimum cooling power as the component target operating parameter to ensure that the optimal cooling power of the liquid cooling system is obtained.

[0133] S420: If not, perform a second adjustment on the opening of the electric two-way valve according to the total cooling power and the current operating parameters of the component, and obtain the target operating parameters of the component according to the second adjustment.

[0134] In this embodiment, if the outside air temperature value is less than the temperature threshold, it means that the outside air temperature is relatively low relative to the temperature threshold, and the opening of the electric two-way valve needs to be adjusted to find the target operating parameters of the components corresponding to the optimal operating state of the liquid cooling system.

[0135] Specifically, if Figure 6 Performing a second adjustment on the opening of the electric two-way valve according to the total cooling power and the current operating parameters of the component, and obtaining the target operating parameters of the component according to the second adjustment, may include the following steps:

[0136] S421, obtaining the current opening of the electric two-way valve according to the current operating parameters of the component;

[0137] In this embodiment, all adjustment operations in this embodiment are performed after the operation of the primary side and the secondary side user side reaches a steady state, which can avoid inaccurate data or misjudgment caused by fluctuations or transient changes in the liquid cooling system parameters, and ensure that the liquid cooling system can obtain the target operating parameters of the components in a stable state and achieve energy-saving goals.

[0138] S422, obtaining a maximum threshold value of the electric two-way valve opening;

[0139] In this embodiment, it is necessary to obtain the maximum threshold value of the electric two-way valve opening, which represents the maximum opening to which the electric two-way valve can be adjusted, thereby facilitating the subsequent traversal of the electric two-way valve opening from the current opening to the maximum opening and obtaining the corresponding cooling power.

[0140] S423, gradually increasing the current opening of the electric two-way valve at the same interval of opening values, and correspondingly recording the cooling power of the liquid cooling system and the current operating parameters of the corresponding components at each current opening of the electric two-way valve after the opening is increased. When the current opening of the electric two-way valve after the opening is increased equals the maximum threshold value of the electric two-way valve opening, stopping increasing the current opening of the electric two-way valve;

[0141] In this embodiment, the electric two-way valve opening is gradually increased at intervals, and the increase stops when the electric two-way valve opening reaches the maximum threshold. This ensures that the electric two-way valve opening is traversed to obtain the corresponding cooling power, while ensuring steady-state operation of the primary, secondary, and user sides of the liquid cooling system. This ensures that the adjustment is performed without affecting the normal operation of the liquid cooling system. Preferably, the opening value can be within the range of [5% to 10%] and can be adjusted appropriately based on the actual conditions of the liquid cooling system.

[0142] S424. Obtain the minimum value of the total cooling power and the cooling power of the liquid cooling system at the current opening of each electric two-way valve after the gear is increased as the third minimum cooling power, and use the current operating parameters of the component corresponding to the third minimum cooling power as the target operating parameters of the component.

[0143] In this embodiment, the minimum value of the total cooling power and the cooling power of the liquid cooling system at the current opening of each electric two-way valve is obtained as the third minimum cooling power, and the minimum cooling power of the electric two-way valve at each opening in the steady state of the liquid cooling system can be found, so that the current operating parameters of the components corresponding to the third minimum cooling power are used as the target operating parameters of the components. Subsequently, the parameters of various components of the liquid cooling system can be adjusted according to the target operating parameters of the components to ensure that the liquid cooling system operates at the third minimum cooling power.

[0144] S500: Regulate components of the liquid cooling system according to target operating parameters of the components, so that the liquid cooling system can operate stably and energy-efficiently.

[0145] In this embodiment, the pipelines on each side of the liquid cooling system are coordinated and controlled according to the corresponding adjustments, and the target operating parameters of the components of the liquid cooling system are obtained. The parameters of each component of the liquid cooling system are adjusted according to the target operating parameters of the components, thereby reducing the overall energy consumption of the liquid cooling system and ensuring that the entire liquid cooling system operates in the optimal state at the minimum cooling power.
