Description

Technical Field

[0001] This invention relates to the field of refrigeration technology, and in particular to a method for controlling the operation of liquid cooling equipment, liquid cooling equipment, and a computer-readable storage medium. Background Technology

[0002] Liquid cooling equipment is suitable for cooling "special users". It is a flexible mobile device for multiple areas and needs to be used in different ambient temperatures. The previous equipment had a maximum ambient temperature limit of 55℃, which is sufficient for use in most tropical and subtropical areas.

[0003] Liquid cooling equipment operates in environments with a wide temperature range, from -40℃ to +65℃. To improve product reliability and lifespan, many manufacturers currently adopt a modular design approach, using multiple refrigeration modules in the liquid cooling equipment. However, there is still no method to assess the health of each refrigeration module. Operating strategies for each module often rely on balancing the operation by accumulating compressor running time, without considering the health of other components, making it difficult to truly evaluate the reliability of the refrigeration module.

[0004] Patent application CN121968542A discloses a high-efficiency chiller room group control system and its control method based on multi-objective optimization. The system includes a group control center, multiple chiller units, multiple chilled water pumps, and multiple cooling towers and cooling water pumps, all signal-connected to the group control center. It also includes: a data acquisition module for real-time acquisition of operating parameters from the multiple chiller units, chilled water pumps, and cooling towers and cooling water pumps; and a health prediction module, signal-connected to the data acquisition module, for receiving the operating parameters from the data acquisition module. Compared with existing technologies, the advantages lie in balancing the health loss among similar equipment through the multi-objective optimization module, avoiding premature damage from prolonged high-load operation of some equipment, promoting relative coordination within the equipment cluster, extending the overall service life, and maximizing operation within the high-efficiency range. It also reduces energy waste caused by malfunctions, inefficient operation, or unnecessary simultaneous operation of equipment, thereby reducing overall operating energy consumption. However, the application scope of this patent application is limited to high-efficiency data center group control systems. The entire application only describes a design concept and lacks a practical implementation plan. Although it mentions model training and periodic updates based on the operating parameters of the chiller unit and the historical maintenance and fault records of the corresponding equipment to output a quantitative health score, it does not explain in detail how to calculate the health score based on the above parameters and records. It only stays at the conceptual design level and is not referable or feasible. Moreover, this concept is a well-known idea among designers in related fields.

[0005] Therefore, how to provide an effective control method to improve the operational reliability and lifespan of liquid cooling equipment is a technical problem that the industry urgently needs to solve. Summary of the Invention

[0006] The purpose of this invention is to provide a liquid cooling equipment operation control method, a liquid cooling equipment, and a computer-readable storage medium to extend the service life of the liquid cooling equipment.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0008] In a first aspect, the present invention proposes a method for controlling the operation of a liquid cooling device, comprising the following steps:

[0009] During the health management process, the actual liquid supply temperature Ts of the liquid cooling equipment is monitored and compared with the target liquid supply temperature Tm.

[0010] If the actual liquid supply temperature Ts is not equal to the target liquid supply temperature Tm, then the start / stop status of each refrigeration module is controlled according to the module health value of each refrigeration module in the liquid cooling equipment.

[0011] The module health value is calculated based on the first device health value of each device in the corresponding refrigeration module and the corresponding weighting coefficient.

[0012] Furthermore, if the actual liquid supply temperature Ts is not equal to the target liquid supply temperature Tm, then controlling the start / stop status of each refrigeration module according to the module health value of each refrigeration module in the liquid cooling equipment specifically includes the following steps:

[0013] When the actual liquid supply temperature Ts is higher than the target liquid supply temperature Tm, first determine whether there is a sub-healthy module whose module health value is lower than the first preset health value.

[0014] If not, then all the aforementioned cooling modules will be turned on first;

[0015] If present, all cooling modules other than the sub-health module will be activated first.

[0016] Furthermore, after prioritizing the activation of all the aforementioned cooling modules, the following steps are also included:

[0017] When the actual liquid supply temperature Ts decreases but is still higher than the target liquid supply temperature Tm, it is then determined whether the difference between the module health values ​​of any two refrigeration modules is lower than the preset health difference value.

[0018] If so, the cooling module with the lowest health value will be frequency-reduced.

[0019] If not, then the cooling module whose module health value is higher than the first preset health value and lower than the second preset health value will be frequency reduced.

[0020] Furthermore, after prioritizing the activation of cooling modules other than the sub-health module, the following steps are also included:

[0021] When the actual liquid supply temperature Ts decreases but remains higher than the target liquid supply temperature Tm, then at least one of the cooling modules in the sub-health module whose module health value is higher than the third preset health value is activated.

[0022] Furthermore, if the actual liquid supply temperature Ts is not equal to the target liquid supply temperature Tm, then controlling the start / stop status of each refrigeration module according to the module health value of each refrigeration module in the liquid cooling equipment specifically includes the following steps:

[0023] When the actual liquid supply temperature Ts is lower than the target liquid supply temperature Tm, first determine whether there is a sub-healthy module whose module health value is lower than the first preset health value. If so, the sub-healthy module is shut down first.

[0024] Furthermore, after prioritizing the shutdown of the sub-health module, the following is also included:

[0025] When the actual liquid supply temperature Ts rises but is still lower than the target liquid supply temperature Tm, the other cooling modules, excluding the sub-healthy module, are then frequency-reduced in order of their health values ​​from low to high.

[0026] Furthermore, the formula for calculating the module's health value is as follows:

[0027] A=B1*C1+B2*C2+B3*C3+B4*C4+B5*C5+B6*C6, C1+C2+C3+C4+C5+C6=1;

[0028] Where A is the module health value, B1 is the compressor health value, C1 is the compressor weight coefficient, B2 is the evaporator health value, C2 is the evaporator weight coefficient, B4 is the condenser health value, C4 is the condenser weight coefficient, B5 is the fan health value, C5 is the fan weight coefficient, B6 is the sensor health value, and C6 is the sensor weight coefficient.

[0029] Furthermore, the health management process also includes the following steps:

[0030] Obtain the second device health value of other devices in the liquid cooling device besides the refrigeration module;

[0031] The start / stop status of the corresponding device is controlled based on the health value of the second device.

[0032] Furthermore, the following steps are included before implementing health management:

[0033] Determine whether the liquid cooling equipment is in the midst of an emergency mission;

[0034] If so, the cooling modules are turned on sequentially according to the set turn-on order, so that the actual liquid supply temperature Ts approaches the target liquid supply temperature Tm;

[0035] If not, then perform the described health management;

[0036] The activation sequence is set as follows: first, activate the cooling modules whose module health value is higher than the first preset health value; second, activate the cooling modules whose module health value is lower than the first preset health value but higher than the third preset health value; and finally, activate the remaining cooling modules.

[0037] Secondly, the present invention provides a liquid cooling device, including a main controller, and a plurality of refrigeration modules and other devices respectively connected to the main controller, wherein the main controller executes the above-described liquid cooling device operation control method.

[0038] Thirdly, the present invention provides a computer-readable storage medium for storing a computer program, wherein the computer program executes the above-described liquid cooling device operation control method when it is run.

[0039] Compared with existing technologies, this invention dynamically adjusts the start-up and shutdown status of modules by comparing the actual supply liquid temperature with the target supply liquid temperature in real time and combining the module health values ​​of each refrigeration module. This balances the losses of each module while meeting temperature control requirements, effectively extending the overall service life of the liquid cooling equipment. The module health value is calculated by combining the health status of each core component within the refrigeration module and its corresponding weighting coefficient. It accurately reflects the actual health level of a single module, providing a precise and reliable decision-making basis for start-up and shutdown adjustments. This approach balances the temperature control capability and operational reliability of the liquid cooling equipment, and also provides clear guidance for subsequent operation and maintenance, improving the operational stability of the liquid cooling equipment throughout its entire lifecycle.

[0056] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the present invention and are not intended to limit the present invention.

[0057] Liquid cooling equipment is suitable for the cooling needs of "special users" and is a flexible, multi-zone mobile device that needs to adapt to different ambient temperatures. Previous equipment had a maximum ambient temperature limit of 55℃, which was sufficient to meet the needs of most tropical and subtropical regions.

[0058] Liquid cooling equipment operates in environments with a wide temperature range, from -40°C to +65°C. To improve operational reliability and lifespan, most manufacturers currently adopt a modular design approach, integrating multiple refrigeration modules into the liquid cooling system. However, to date, a unified method for assessing the health of these refrigeration modules has not been established. Operational strategies for each module often rely on accumulating compressor operating time for balanced control, without considering the health status of other components, making it difficult to accurately evaluate the reliability of the refrigeration modules.

[0059] Patent application CN121968542A discloses a high-efficiency chiller room group control system and its control method based on multi-objective optimization. The system includes a group control center, multiple chiller units, multiple chilled water pumps, and multiple cooling towers and cooling water pumps, all signal-connected to the group control center. It also includes: a data acquisition module for real-time acquisition of operating parameters from the multiple chiller units, chilled water pumps, and cooling towers and cooling water pumps; and a health prediction module, signal-connected to the data acquisition module, for receiving the operating parameters from the data acquisition module. Compared with existing technologies, the advantages lie in balancing the health loss among similar equipment through the multi-objective optimization module, avoiding premature damage from prolonged high-load operation of some equipment, promoting relative coordination within the equipment cluster, extending the overall service life, and maximizing operation within the high-efficiency range. It also reduces energy waste caused by malfunctions, inefficient operation, or unnecessary simultaneous operation of equipment, thereby reducing overall operating energy consumption.

[0060] However, the patent application focuses on high-efficiency data center group control systems, and only describes a design concept without providing a practical implementation plan. The patent mentions "training and periodically updating based on the operating parameters of each chiller unit and the corresponding equipment's historical maintenance and fault records to output a quantitative health score," but it doesn't explain in detail how to generate the health score based on these parameters and records, remaining only at the conceptual design level and lacking reference value and feasibility. Such concepts are common knowledge among designers in related fields; the specific implementation method should be the core focus of the patent's protection.

[0061] This invention protects a liquid cooling device (standalone device) and its health scoring system and control method. It provides a detailed description of the specific product, the implementable control method, and user management measures, which is fundamentally different from the aforementioned patent application.

[0062] like Figure 1 As shown, the liquid cooling equipment operation control method proposed in this invention includes the following steps:

[0063] During the health management process, the actual liquid supply temperature Ts of the liquid cooling equipment is monitored and compared with the target liquid supply temperature Tm.

[0064] If the actual liquid supply temperature Ts is not equal to the target liquid supply temperature Tm, the start-stop status of each refrigeration module is controlled according to the module health value of each refrigeration module in the liquid cooling equipment.

[0065] The module health value is calculated based on the first device health value and corresponding weighting coefficient of each device in the corresponding refrigeration module.

[0066] Compared with existing technologies, this invention dynamically adjusts the start-up and shutdown status of modules by comparing the actual supply liquid temperature with the target supply liquid temperature in real time and combining the module health values ​​of each refrigeration module. This balances the losses of each module while meeting temperature control requirements, effectively extending the overall service life of the liquid cooling equipment. The module health value is calculated by combining the health status of each core component within the refrigeration module and its corresponding weighting coefficient. It accurately reflects the actual health level of a single module, providing a precise and reliable decision-making basis for start-up and shutdown adjustments. This approach balances the temperature control capability and operational reliability of the liquid cooling equipment, and also provides clear guidance for subsequent operation and maintenance, improving the operational stability of the liquid cooling equipment throughout its entire lifecycle.

[0067] Among them, such as Figure 2 As shown, if the actual liquid supply temperature Ts is not equal to the target liquid supply temperature Tm, then the start / stop status of each refrigeration module is controlled according to the module health value of each refrigeration module in the liquid cooling equipment, specifically including the following steps:

[0068] When the actual liquid supply temperature Ts is higher than the target liquid supply temperature Tm, first determine whether there are sub-healthy modules whose module health value is lower than the first preset health value.

[0069] If not, then all cooling modules will be turned on first;

[0070] If present, prioritize activating all cooling modules except the sub-health module.

[0071] Therefore, when the actual liquid supply temperature is too high and increased cooling capacity is needed, priority can be given to putting the cooling modules in better health into operation, while modules in better health will be degraded first. This avoids the continued high-load operation of sub-healthy modules, which could further aggravate wear and tear and cause malfunctions. This approach can quickly replenish cooling capacity to meet temperature control requirements, slow down the aging process of sub-healthy modules, balance the wear rate of each module, and thus improve the operational reliability and service life of the liquid cooling equipment.

[0072] like Figure 3 As shown, after activating all cooling modules first, the following steps are also included:

[0073] When the actual liquid supply temperature Ts drops but is still higher than the target liquid supply temperature Tm, then it is determined whether the difference between the module health values ​​of any two refrigeration modules is lower than the preset health difference value.

[0074] If so, the cooling module with the lowest health value will be frequency-reduced;

[0075] If not, then the frequency reduction process will be applied to the cooling modules whose module health value is higher than the first preset health value but lower than the second preset health value.

[0076] Therefore, when all healthy modules are in operation, if the actual liquid supply temperature drops but still does not reach the target value, the frequency can be reduced to balance the losses of modules in different health states, preventing the wear rate of modules with significantly different health states from further increasing. This measure, while meeting temperature control requirements, can further balance the lifespan of each refrigeration module, ensuring the continuous and stable operation of the liquid cooling equipment as a whole.

[0077] To facilitate understanding, the following example is provided:

[0078] The first preset health value is 60 points. Refrigeration modules with a health value below 60 points are considered sub-healthy, while those with a value of 60 points or higher are considered healthy. Furthermore, the second preset health value is 70 points, with a preset health difference of 20 points.

[0079] If the module health value of all refrigeration modules in the liquid cooling equipment is greater than 60 points, and the difference between the module health values ​​of any two modules is less than 20 points: when the actual liquid supply temperature Ts is higher than the target liquid supply temperature Tm, all refrigeration modules are turned on first and run at an energy-saving frequency; if Ts drops significantly after being turned on but is still higher than Tm, the refrigeration module with the lowest module health value is frequency-reduced; conversely, if Ts does not drop significantly, the refrigeration module with the highest module health value is frequency-increased, and maintenance recommendations for regular inspections can be given.

[0080] If the module health value of all refrigeration modules in the liquid cooling equipment is greater than 60 points, and there are refrigeration modules with health values ​​of 60, 65, and 100 points: when the actual liquid supply temperature Ts is higher than the target liquid supply temperature Tm, all refrigeration modules will be turned on first and run at the energy-saving frequency; if Ts decreases significantly after being turned on but is still higher than Tm, the refrigeration modules with health values ​​of 60 and 65 points will be frequency-reduced, and the remaining refrigeration modules will maintain the energy-saving frequency. At the same time, maintenance and upkeep suggestions for regular inspections can be given.

[0081] like Figure 4 As shown, after prioritizing the activation of cooling modules other than the sub-health module, the following steps are also included:

[0082] When the actual liquid supply temperature Ts drops but remains higher than the target liquid supply temperature Tm, then at least one cooling module in the sub-health module whose module health value is higher than the third preset health value is activated.

[0083] Therefore, when the temperature control requirements cannot be met by relying solely on the healthy modules, the relatively healthy sub-healthy modules can be activated to supplement the cooling capacity. This strategy prioritizes temperature control while minimizing the use of sub-healthy modules with higher wear and tear, balancing the needs for temperature control reliability with the evenness of module wear, thereby improving the operational reliability and service life of the liquid cooling equipment.

[0084] To facilitate understanding, the following example is provided:

[0085] The first preset health value is 60 points. Refrigeration modules with a health value below 60 points are considered sub-healthy, while those with a value of 60 points or higher are considered healthy. Additionally, the third preset health value is 30 points.

[0086] If the module health value of some refrigeration modules in the liquid cooling equipment is higher than 60 points, and the module health value of the remaining refrigeration modules is between 30 and 60 points (i.e., lower than 60 points but higher than 30 points): when the actual liquid supply temperature Ts is higher than the target liquid supply temperature Tm, all refrigeration modules with a module health value higher than 60 points should be turned on first and run at high frequency; if Ts decreases after being turned on but is still higher than Tm, then the module with the highest module health value among the remaining refrigeration modules should be turned on and run at medium and low frequency, and a health warning should be popped up, suggesting that the maintenance of refrigeration modules with a module health value lower than 60 points should be strengthened.

[0087] If some refrigeration modules in the liquid cooling system have a health score above 60, some between 30 and 60, and the rest below 30: When the actual liquid supply temperature Ts is higher than the target liquid supply temperature Tm, prioritize turning on all refrigeration modules with a health score above 60 and running them at high frequency. If Ts decreases after turning them on but remains above Tm, turn on the refrigeration modules with a health score between 30 and 60 and run them at medium frequency. Refrigeration modules with a health score below 30 should remain off. Simultaneously, request the liquid cooling system to appropriately increase the target liquid supply temperature by 1-2°C. The resulting deviation in cooling output will be compensated by the refrigeration module with the highest health score by increasing the operating frequency of its compressor and fan. Furthermore, a health warning will pop up, recommending enhanced maintenance of refrigeration modules with a health score below 60 and requesting repair of refrigeration modules with a health score below 30.

[0088] In addition, such as Figure 5 As shown, if the actual liquid supply temperature Ts is not equal to the target liquid supply temperature Tm, then the start / stop status of each refrigeration module is controlled according to the module health value of each refrigeration module in the liquid cooling equipment, specifically including the following steps:

[0089] When the actual liquid supply temperature Ts is lower than the target liquid supply temperature Tm, first determine whether there are sub-healthy modules whose module health value is lower than the first preset health value. If so, the sub-healthy modules are shut down first.

[0090] Therefore, when the actual liquid supply temperature is too low and the cooling capacity needs to be reduced, the cooling modules with poor health can be shut down first to reduce the operational losses of these modules. This not only allows for rapid adjustment of cooling capacity while meeting temperature control requirements, but also slows down the aging process of the modules in poor health, balances the wear and tear of each module, thereby improving the operational reliability of the liquid cooling equipment and extending its service life.

[0091] like Figure 5 As shown, after prioritizing the shutdown of the sub-health module, it also includes:

[0092] When the actual liquid supply temperature Ts rises but is still lower than the target liquid supply temperature Tm, the other cooling modules, except for the sub-healthy modules, are then frequency-reduced in order of their health values ​​from low to high.

[0093] Therefore, when the actual liquid supply temperature is too low and the cooling capacity needs to be reduced, by first shutting down the sub-healthy modules and then gradually reducing the frequency of the healthy modules, the cooling demand can be accurately matched, avoiding large temperature fluctuations caused by excessive shutdown. At the same time, the operating burden of the healthy modules can be continuously reduced, further balancing the losses of all cooling modules, thereby improving the operational reliability of the liquid cooling equipment and extending its service life.

[0094] To facilitate understanding, the following example is provided:

[0095] The first preset health value is 60 points. That is, a refrigeration module with a health value below 60 points is a sub-healthy module, and a module with a health value of 60 points or above is a healthy module.

[0096] If some refrigeration modules in the liquid cooling equipment have a module health value higher than 60 points and the rest are lower than 60 points: When the actual liquid supply temperature Ts is lower than the target liquid supply temperature Tm, prioritize shutting down all refrigeration modules with a module health value lower than 60 points; if Ts rises after shutdown but is still lower than Tm, then adjust all refrigeration modules with a module health value higher than 60 points to energy-saving frequency operation in order of module health value from low to high; if Ts is still lower than Tm after adjustment, then adjust all refrigeration modules with a module health value higher than 60 points to low-frequency operation; if Ts is still lower than Tm at this time, then shut down refrigeration modules with a module health value higher than 60 points in order of module health value from low to high.

[0097] The aforementioned adjustment of the operating frequency of the refrigeration module (such as frequency increase and frequency decrease) specifically targets the operating frequency of the fan and compressor in the refrigeration module. When adjusting the operating frequency of the two, the frequency of the device with relatively better or worse health status can be adjusted first, based on the health value of the first device corresponding to the fan and compressor.

[0098] Furthermore, the formula for calculating the module's health value is as follows:

[0099] A=B1*C1+B2*C2+B3*C3+B4*C4+B5*C5+B6*C6, C1+C2+C3+C4+C5+C6=1;

[0100] Where A is the module health value, B1 is the compressor health value, C1 is the compressor weight coefficient, B2 is the evaporator health value, C2 is the evaporator weight coefficient, B4 is the condenser health value, C4 is the condenser weight coefficient, B5 is the fan health value, C5 is the fan weight coefficient, B6 is the sensor health value, and C6 is the sensor weight coefficient.

[0101] Therefore, the module health value of a single refrigeration module can be obtained through the above calculation formula. This value is obtained by weighting the health values ​​of different core components, which can more accurately reflect the actual operating health status of a single refrigeration module, avoiding the bias in health judgment caused by a single dimension assessment. This provides a more accurate and reliable decision-making basis for subsequent control operations such as shutting down and adjusting the frequency of refrigeration modules. This not only helps to ensure the overall temperature stability of the liquid cooling equipment, but also allows for a more reasonable allocation of the operating time of modules in different health states, delaying module aging and thus extending the overall service life of the liquid cooling equipment.

[0102] To facilitate understanding, the following example is provided:

[0103] The module health value range and corresponding health evaluation for a single refrigeration module are as follows:

[0104] 0~10 points: Health level is extremely poor, and the machine is not allowed to be turned on and run;

[0105] 11-30 points: Health status is poor, and the number of times the machine is turned on and the running time should be reduced as much as possible;

[0106] 51-60 points: Health status is good; appropriately reduce the number of times the device is turned on and the running time.

[0107] 61-80 points: Health level is medium, can be used normally;

[0108] 81~100 points: Health is excellent, can be started first and allowed to run for a long time.

[0109] The weighting coefficient for the compressor is 30%, for the evaporator it is 20%, for the condenser it is 20%, for the fan it is 20%, and for the sensor it is 10%.

[0110] The method for evaluating the first component health value of each component within the cooling module is as follows:

[0111] a. Compressor:

[0112] The initial health score is 100.

[0113] For every 500 hours of accumulated running time, 1 point is deducted from the health value;

[0114] When the operating current reaches 90% of the normal upper limit, the health value is deducted by 5 points;

[0115] When the operating current is between 100% and 110% of the normal upper limit, the health value is deducted by 15 points;

[0116] When the operating current exceeds the normal upper limit by 10%~15% (i.e. 110%~115%), the health value will be deducted by 30 points;

[0117] When the operating current exceeds the normal upper limit by 15%~20% (i.e. 115%~120%), the health value will be deducted by 40 points;

[0118] When the operating current exceeds the normal upper limit by 20%~25% (i.e. 120%~125%), the health value will be deducted by 70 points;

[0119] When the operating current exceeds the normal upper limit by more than 25% (i.e., more than 125%), the health value will be deducted by 90 points;

[0120] When the inhalation superheat is 0°C, 90 points are deducted from the health score.

[0121] If the inhalation overheat is between 1 and 2°C, 60 points will be deducted from the health score.

[0122] If the inhalation overheat is between 3 and 5°C, 40 points will be deducted from the health score.

[0123] When the inhalation superheat is between 6 and 10°C, no points will be deducted from the health score.

[0124] If the inhalation temperature exceeds 11°C, 60 points will be deducted from the health score.

[0125] b. Fan:

[0126] The initial health score is 100.

[0127] For every 500 hours of accumulated running time, 1 point is deducted from the health value;

[0128] When the operating current reaches 90% of the normal upper limit, the health value is deducted by 5 points;

[0129] When the operating current is between 100% and 110% of the normal upper limit, the health value is deducted by 15 points;

[0130] When the operating current exceeds the normal upper limit by 10%~15% (i.e. 110%~115%), the health value will be deducted by 30 points;

[0131] When the operating current exceeds the normal upper limit by 15%~20% (i.e. 115%~120%), the health value will be deducted by 40 points;

[0132] When the operating current exceeds the normal upper limit by 20%~25% (i.e. 120%~125%), the health value will be deducted by 70 points;

[0133] When the operating current exceeds the normal upper limit by more than 25% (i.e., more than 125%), the health value will be deducted by 90 points.

[0134] c. Condenser:

[0135] The initial health score is 100.

[0136] The terminal temperature difference refers to the difference between the condensation temperature in the condenser and the outlet temperature of the cooling medium. It is an important indicator for measuring the heat exchange efficiency of the condenser, and its initial value is defined as ΔT.

[0137] When the temperature difference between the ends is between ΔT+1 and 3℃, 10 points will be deducted from the health score.

[0138] When the temperature difference between the ends is between ΔT+4 and 5℃, 20 points will be deducted from the health score.

[0139] When the temperature difference between the ends is between ΔT+6 and 8℃, 40 points will be deducted from the health score.

[0140] When the temperature difference between the ends is between ΔT+9 and 15℃, 60 points will be deducted from the health score.

[0141] When the temperature difference between the ends is between ΔT+16 and 20℃, 70 points will be deducted from the health score.

[0142] When the temperature difference between the ends reaches △T+21℃ or above, the health score will be deducted by 80 points.

[0143] d. Evaporator:

[0144] The initial health score is 100.

[0145] For every additional 1000 hours of accumulated running time, 5 points will be deducted from the health value.

[0146] e. Sensors:

[0147] The initial health score is 100.

[0148] For every 500 hours of accumulated running time, 3 points will be deducted from the health value;

[0149] Each time a malfunction occurs and repairs are performed, 30 points are deducted from the health value.

[0150] In addition, the health management process also includes the following steps:

[0151] Obtain the second device health value of other components in the liquid cooling equipment besides the refrigeration module;

[0152] The start / stop status of the corresponding device is controlled based on the health value of the second device.

[0153] Therefore, by conducting health status assessments on components other than the refrigeration module separately, it is possible to more accurately pinpoint the overall health risk points of the liquid cooling equipment. Combining health scoring with component operation status management can prevent malfunctions caused by faulty components and remind maintenance personnel to promptly maintain or replace components with low health values, thereby ensuring the overall stability of the liquid cooling system and reducing losses caused by sudden downtime.

[0154] It should be understood that other components in liquid cooling equipment besides the refrigeration module include water pumps, flow meters, filters, electric heaters, sensors, etc. The evaluation method for the health value of these components is similar to that for the sensors in the refrigeration module. For example, the initial health value is 100 points; for every 500 hours of accumulated operating time, 3 points are deducted from the health value; for each fault repair, 30 points are deducted from the health value. This will not be elaborated further here.

[0155] The health management rules for devices such as water pumps and electric heaters are as follows: If the device is fault-free, prioritize starting the device with the shortest cumulative running time among similar devices; if the device is faulty, start the similar fault-free device and remind the user to replace or repair it in time; if the device is fault-free but the health value is below 60, remind the user to carry out inspection and maintenance.

[0156] The health management rules for sensors and other devices are as follows: If the device parameter curve is abnormal compared to the historical curve, and the parameters of two similar devices are different, the abnormal parameters will be masked to prevent them from participating in the control of the liquid cooling equipment, and the user will be reminded to perform maintenance; if the device has reached the maintenance point or replacement point of its lifespan curve, the user will be reminded to perform maintenance or replacement.

[0157] It should be noted that after completing the health scoring of the refrigeration modules and other components, the equipment health value of the liquid cooling equipment can be further calculated to assess the overall health status of the equipment. Specifically, the equipment health value is calculated by weighting the module health value of each refrigeration module with the secondary device health values ​​of other components: if the equipment contains N refrigeration modules and M other components, then the weighting coefficient for each refrigeration module is 60% / N, and the weighting coefficient for each other component is 40% / M.

[0158] The equipment health value ranges and corresponding health assessments for liquid cooling equipment are as follows:

[0159] 0~10 points: Health level is extremely poor, do not turn on the machine and maintain it immediately (temporary turn-on is allowed for emergency tasks).

[0160] 11~30 points: Health status is poor. Minimize the number of times the device is turned on and the running time. Maintenance and upkeep are required as soon as possible.

[0161] 51-60 points: Health level is good; maintenance is recommended as soon as possible.

[0162] 61-80 points: Health level is medium, it is recommended to increase the frequency of daily check-ups;

[0163] 81~100 points: Excellent health rating, can be used normally, just carry out routine checks as planned.

[0164] In addition, such as Figure 6 As shown, the following steps are included before implementing health management:

[0165] Determine if the liquid cooling equipment is in an emergency operation;

[0166] If so, the cooling modules will be turned on sequentially according to the set turn-on order, so that the actual liquid supply temperature Ts approaches the target liquid supply temperature Tm.

[0167] If not, then implement health management;

[0168] The activation order is set as follows: first, activate the cooling modules whose module health value is higher than the first preset health value; second, activate the cooling modules whose module health value is lower than the first preset health value but higher than the third preset health value; and finally, activate the remaining cooling modules.

[0169] Therefore, in emergency mission scenarios, priority is given to ensuring the liquid supply demand. At the same time, by activating the cooling modules in descending order of module health values, the activation of modules with poor health conditions can be reduced while meeting the liquid supply temperature requirements, thereby reducing the probability of sudden module failures and avoiding equipment abnormalities during emergency missions. In non-emergency missions, health management is performed first, which allows for early monitoring of the equipment's health status, timely maintenance, and ensures the long-term stable operation of the liquid cooling equipment.

[0170] To facilitate understanding, the following example is provided:

[0171] The first preset health value is 60 points, and the third preset health value is 30 points.

[0172] If the liquid cooling equipment is in an emergency, prioritize activating all cooling modules with a health value above 60 and running them at high frequency to ensure stable liquid supply temperature. If the liquid supply temperature does not reach the target value, then activate all cooling modules with a health value between 30 and 60 to continue ensuring stable liquid supply temperature. At this point, the interface will display "All healthy modules are running at high frequency, and relatively healthy modules have been activated." If the liquid supply temperature still does not reach the target value, finally activate the cooling modules with a health value below 30 and no faults to further ensure stable liquid supply temperature. The interface will simultaneously display "All healthy modules have been activated, and the estimated operating time is XXX hours."

[0173] The liquid cooling device provided by the present invention includes a main controller, and a plurality of refrigeration modules and other devices respectively connected to the main controller. The main controller executes the above-described liquid cooling device operation control method.

[0174] The aforementioned liquid cooling equipment operation control method dynamically adjusts the start-up and shutdown status of modules by comparing the actual supply liquid temperature with the target supply liquid temperature in real time and combining the module health values ​​of each refrigeration module. This balances the losses of each module while meeting temperature control requirements, effectively extending the overall service life of the equipment. The module health value is calculated by comprehensively considering the health status of each core component within the refrigeration module and its corresponding weighting coefficients. It accurately reflects the actual health level of a single module, providing a precise and reliable basis for module start-up and shutdown adjustments. This method balances the temperature control capability and operational reliability of the liquid cooling equipment, and also provides clear guidance for subsequent operation and maintenance, helping to improve the operational stability throughout the equipment's lifecycle. Therefore, it enables the liquid cooling equipment to have a better service life and operational reliability.

[0175] For ease of understanding, the specific structure of the liquid cooling equipment and its operation control method will be described in detail using a preferred embodiment as an example.

[0176] In the preferred embodiment, see Figure 9 and Figure 10 The liquid cooling equipment consists of a frame 1, six refrigeration modules 2, a liquid supply system (including water pumps, water tanks, filters, flow meters, valves, electric heaters, sensors, etc.), a main controller (including a high-voltage electrical control box 3 and a low-voltage electrical control box 4), and a toolbox 5. The main liquid supply port 6 and main liquid return port 7 are used to connect to the coolant pipelines of "special users": the main liquid supply port 6 supplies low-temperature ethylene glycol coolant to the "special users," while the main liquid return port 7 allows the coolant to flow back into the equipment. The six refrigeration modules 2 are installed on the upper layer of the frame 1, and this layer has louvers 8 on its side, which serve as both air intake for the refrigeration modules 2 and a maintenance access point. The lower layer of the frame 1 has maintenance doors 9 corresponding to the low-voltage electrical control box 4 and the high-voltage electrical control box 3, respectively.

[0177] Refrigeration module 2 is an independent air-cooled chiller, equipped with an independent control box. It communicates with and is centrally controlled by the low-voltage control box 4 of the liquid cooling equipment, while power supply is provided by the high-voltage control box 3. The liquid cooling equipment is used for cooling special equipment such as "special users," and is an outdoor device with an applicable ambient temperature range of -40~65℃, requiring normal cooling within this temperature range. The coolant used is ethylene glycol solution. The equipment is containerized, employing a side return air (ambient air) and top exhaust air design (which can also be adjusted to one-sided return air and one-sided exhaust air depending on the type of refrigeration module 2 or the user's site requirements). The control box is located inside a non-louvered door, and its ambient temperature is consistent with the overall ambient temperature of the liquid cooling equipment.

[0178] See Figure 11Each refrigeration module 2 includes components such as a compressor 21, a condenser 22, a throttle valve 23, an evaporator 24, a vapor-liquid separator 25, a fan 26, and sensors. The compressor 21, condenser 22, throttle valve 23, evaporator 24, and vapor-liquid separator 25 are connected via refrigerant piping to form a refrigeration circuit, allowing the refrigerant to circulate within the circuit. The evaporator 24 is connected via coolant piping to the main return pipe and main supply pipe to form a coolant supply circuit, enabling coolant circulation. The fan 26 enhances the heat exchange efficiency between the condenser 22 and the environment.

[0179] See Figure 12 The six refrigeration modules 2 are arranged in parallel. The liquid inlet of each refrigeration module 2 is thermally coupled to the heat load through the main return pipe of the liquid cooling equipment, and the liquid outlet is thermally coupled to the heat load through the main supply pipe, so as to realize the circulation of coolant between the heat load and the liquid cooling equipment: the coolant after flowing through the heat load flows into the main return pipe through the main return port 7, then flows to the liquid inlet of the activated refrigeration module 2 and enters the module. After being cooled, it flows out from the module's liquid outlet to the main supply pipe, and finally flows to the heat load through the main supply port 6 to cool and dissipate heat from the heat load and prevent it from being damaged due to excessive temperature.

[0180] The operation of liquid cooling equipment can be briefly described as follows: The main controller uniformly schedules the number of refrigeration modules to be turned on based on the user load (reflected by changes in the liquid supply temperature) and determines their priority operation order or whether to turn them on or off based on the health values ​​of each module; at the same time, it performs a health assessment of the entire equipment and provides maintenance suggestions to the user. Each refrigeration module controls the operating frequency of its compressor and fan based on its own liquid supply temperature, assesses the health of its own components, and reports the overall health data of the module to the main controller. The liquid supply temperature of the liquid cooling equipment must ensure reliable and stable operation of the user load, while the liquid supply temperature of the refrigeration modules must ensure the stability of the overall liquid supply temperature of the equipment. After the user sets the liquid supply temperature of the liquid cooling equipment, the main controller sends the set value to each refrigeration module as its target liquid supply temperature value.

[0181] See Figure 7 and Figure 8 The specific operation and control methods for liquid cooling equipment are as follows:

[0182] If the liquid cooling equipment is in an emergency, prioritize activating all cooling modules with a health value above 60 and running them at high frequency to ensure stable liquid supply temperature. If the liquid supply temperature does not reach the target value, activate all cooling modules with a health value between 30 and 60 to continue ensuring stable liquid supply temperature. At this time, the interface will display "All healthy modules are running at high frequency, and the better sub-healthy modules have been activated." If the liquid supply temperature still does not reach the target value, finally activate the cooling modules with a health value below 30 and no faults to further ensure stable liquid supply temperature. The interface will simultaneously display "All sub-healthy modules have been activated, and the estimated running time is XXX hours."

[0183] If the liquid cooling equipment is not in an emergency operation, health management is performed. During health management, the operation of multiple cooling modules is scheduled, as follows:

[0184] When the actual supply temperature Ts is higher than the target supply temperature Tm:

[0185] If the module health value of all refrigeration modules in the liquid cooling equipment is greater than 60 points, and the difference between the module health values ​​of any two modules is less than 20 points, all refrigeration modules will be turned on first and run at the energy-saving frequency. If Ts decreases significantly after turning on but is still higher than Tm, the refrigeration module with the lowest module health value will be frequency-reduced. Conversely, if Ts does not decrease significantly, the refrigeration module with the highest module health value will be frequency-increased, and maintenance recommendations for regular inspections will be given.

[0186] If the health values ​​of all refrigeration modules in the liquid cooling equipment are greater than 60 points, but the difference between the health values ​​of two modules is greater than 20 points, all refrigeration modules will be turned on first and run at the energy-saving frequency. If Ts decreases significantly after being turned on but is still higher than Tm, the refrigeration modules with health values ​​below 70 points will be frequency-reduced, while the remaining refrigeration modules with health values ​​above 70 points will maintain the energy-saving frequency. At the same time, maintenance recommendations for regular inspections will be given.

[0187] If the module health value of some refrigeration modules in the liquid cooling equipment is higher than 60 points, and the module health value of the remaining refrigeration modules is between 30 and 60 points (i.e., lower than 60 points but higher than 30 points), prioritize turning on all refrigeration modules with a module health value higher than 60 points and running them at high frequency; if Ts decreases after turning them on but is still higher than Tm, then turn on the module with the highest module health value among the remaining refrigeration modules and run it at medium to low frequency, and at the same time pop up a health warning, suggesting that the maintenance of refrigeration modules with a module health value lower than 60 points be strengthened.

[0188] If some refrigeration modules in the liquid cooling system have a health score above 60, some between 30 and 60, and the rest below 30, prioritize starting all refrigeration modules with a health score above 60 and running them at high frequency. If, after starting, Ts decreases but remains above Tm, then start the refrigeration modules with a health score between 30 and 60 and run them at medium frequency. Refrigeration modules with a health score below 30 should remain off. Simultaneously, request the liquid cooling system to appropriately increase the target liquid supply temperature by 1-2°C. The resulting deviation in cooling output will be compensated by the refrigeration module with the highest health score by increasing the operating frequency of its compressor and fan. Additionally, a health warning will pop up, recommending enhanced maintenance of refrigeration modules with a health score below 60 and requesting repair of refrigeration modules with a health score below 30.

[0189] When the actual liquid supply temperature Ts is lower than the target liquid supply temperature Tm, prioritize shutting down all cooling modules with a health value below 60. If Ts rises after shutdown but remains below Tm, adjust all cooling modules with a health value above 60 to energy-saving frequency operation in ascending order of module health value. If Ts remains below Tm after adjustment, adjust all cooling modules with a health value above 60 to low-frequency operation. If Ts is still below Tm at this point, shut down cooling modules with a health value above 60 in ascending order of module health value.

[0190] Therefore, this method can significantly balance the lifespan and reliability of multiple refrigeration modules, effectively improving the overall lifespan and operational reliability of liquid cooling equipment. It not only provides a reference for users' operational status monitoring and daily maintenance plan execution, but also lays a reliable foundation for the formulation of emergency task plans.

[0191] Specifically, the user interface of the liquid cooling equipment should support viewing the health assessment values ​​and historical records of all refrigeration modules and components. Health assessments should allow users to view trends via curves, enabling them to flexibly decide whether to initiate maintenance in advance based on these trends and task cycles. For refrigeration modules or components with health values ​​below 60, the system should issue prompts and provide maintenance suggestions, while also predicting the remaining usable time or lifespan based on the health score curve. For component maintenance operations, the controller must record the operation type (repair or replacement): for repair, the accumulated running time is not reset, and the health value is deducted by 30% each time; for replacement, the accumulated running time is reset to zero, and the health value is restored to 100%. The controller for each refrigeration module independently manages its health and reports the data to the main controller of the liquid cooling equipment. The main controller determines the power-on or power-off status of the refrigeration module based on the reported module health value. When the liquid cooling equipment is in an emergency task phase, all non-faulty refrigeration modules and components must prioritize ensuring the stability of the equipment's liquid supply temperature; in this case, stop-inspection commands issued due to health score differences will not be executed.

[0192] Furthermore, the computer-readable storage medium provided by the present invention is used to store a computer program, which executes the above-described liquid cooling equipment operation control method when the computer program is run.

[0193] The aforementioned liquid cooling equipment operation control method dynamically adjusts the start-up and shutdown status of modules by comparing the actual supply liquid temperature with the target supply liquid temperature in real time and combining the health values ​​of each refrigeration module. This balances the losses of each module while meeting temperature control requirements, effectively extending the overall service life of the equipment. The module health value is calculated by comprehensively considering the health status of each core component within the refrigeration module and its corresponding weighting coefficients. This accurately reflects the actual health level of a single module, providing a precise and reliable basis for module start-up and shutdown adjustments. This method considers both the temperature control capability and operational reliability of the liquid cooling equipment, and also provides clear guidance for subsequent operation and maintenance, helping to improve the operational stability throughout the equipment's entire lifecycle, thus giving the liquid cooling equipment a better service life and operational reliability. In particular, by monitoring the status of each component within a single refrigeration module and comprehensively evaluating the operational health of the refrigeration module, it not only provides a reference for the start-up and adjustment of the liquid cooling equipment but also offers suggestions for its maintenance.
