[0016] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this application.

[0017] It should be noted that, in the description of this application, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. The terms "first," "second," etc., in this application are used to distinguish similar objects and are not used to describe a specific order or sequence.

[0018] Commonly used liquid cooling technologies for electronic devices mainly include immersion liquid cooling and cold plate liquid cooling. Cold plate liquid cooling utilizes a cold plate in contact with the heat-generating components of the electronic device for heat dissipation. Its heat dissipation principle involves a water pump driving coolant to continuously flow through the internal channels of the cold plate, allowing the coolant to exchange heat with the heat-generating components through the plate wall, thereby removing the heat generated by the operating components of the electronic device. Cold plate liquid cooling technology is widely used due to its high cooling efficiency.

[0019] The cold plate is the core heat dissipation component of cold plate liquid-cooled electronic equipment, and it is equipped with a coolant inlet and a coolant outlet. In order to achieve a good heat dissipation effect, the internal flow channel design of the cold plate circulation pipe is usually quite complex, which makes the cold plate manufacturing process more complex. As a result, even after cleaning, oil stains and other organic matter may still remain in the inner cavity of the cold plate pipe, which can be introduced into the liquid cooling secondary circulation system during the testing or operation of electronic equipment.

[0020] The presence of organic matter in the coolant can easily breed microorganisms, forming a biofilm on the inner wall of the cold plate piping. This not only affects heat exchange efficiency but also accelerates pipe corrosion. Minerals in the coolant (such as calcium and magnesium ions) tend to precipitate and adhere to the inner wall of the cold plate piping under high-temperature environments, forming scale, which gradually reduces heat exchange efficiency and increases system pressure. Chloride ions and sulfides in the water affect the pH of the water, accelerating pipe corrosion and shortening the service life of the cold plates. Dissolved oxygen in the water may react with iron ions to produce iron oxides, forming rust. These impurities and suspended solids deposited in the pipes can reduce water flow and affect cooling performance.

[0021] To address the technical problems in related technologies, this application provides a heat dissipation device, a heat dissipation management method, and an equipment cluster. The heat dissipation device includes a cooling component, a distribution component, a circulation pipe assembly, a monitoring component, a first purification component, a second purification component, and a control component. The cooling component is used to cool the coolant. The distribution component is connected to the cooling component. The circulation pipe assembly includes a supply pipe and a return pipe, both connected to the distribution component. The supply pipe is connected to the input port of an electronic device, and the return pipe is connected to the output port of the electronic device. The monitoring component is connected to the supply pipe and the return pipe, and is used to monitor the water quality of the coolant flowing through it to obtain monitoring data. The first purification component and the second purification component are located on the return pipe, with one of them serving as the current purification component to purify the coolant. The distribution component connects to the current purification component. The control component includes a control module connected to the monitoring component. The control module acquires the monitoring data, uses the monitoring data for heat dissipation management, and evaluates whether to control the distribution component to switch the connected pipe so that the other of the first and second purification components becomes the new current purification component. To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] The specific application environment architecture or specific hardware architecture on which the thermal management method depends is described here.

[0023] The embodiments of this application provide a heat dissipation device, and the specific heat dissipation principle of the heat dissipation device is described in detail in conjunction with the specific structure of the heat dissipation device.

[0024] Please see Figure 1 , Figure 1 This is a schematic diagram of the structure of an embodiment of the heat dissipation device of this application.

[0025] In one embodiment, the heat dissipation device may include a cooling component 11, a distribution component 12, a circulation tube assembly, a monitoring component 14, a first purification component 151, a second purification component 152, and a control component 16.

[0026] The cooling assembly 11 is used to cool the coolant.

[0027] The distribution component 12 is connected to the cooling component 11.

[0028] The circulation pipe assembly includes a supply pipe 131 and a return pipe 132, both of which are connected to the distribution assembly 12. The supply pipe 131 is connected to the input port 21 of the electronic device 20, and the return pipe 132 is connected to the output port 22 of the electronic device 20.

[0029] The monitoring component 14 is connected to the liquid supply line 131 and the liquid return line 132, and is used to monitor the water quality of the coolant flowing through it to obtain monitoring data.

[0030] The first purification component 151 and the second purification component 152 are located in the return pipeline 132. One of them serves as the current purification component to purify the coolant. The distribution component 12 connects the pipeline between itself and the current purification component.

[0031] The control component 16 is provided with a control module 161 connected to the monitoring component 14.

[0032] The control module 161 is used to acquire monitoring data, use the monitoring data for heat dissipation management, and evaluate whether to control the distribution component 12 to switch the conduction pipeline so that the other of the first purification component 151 and the second purification component 152 becomes the new current purification component.

[0033] In other words, after the cooling component 11 cools the coolant, it is introduced into the supply pipe 131 of the circulation pipe group via the distribution component 12. The coolant flows through the input port 21 of the electronic device 20 to dissipate heat from the equipment, and then flows back through the return pipe 132. The monitoring component 14 monitors the water quality of the coolant in the supply pipe 131 and the return pipe 132 in real time and generates monitoring data. The first purification component 151 and the second purification component 152 on the return pipe 132 are selected as the current purification component, and the distribution component 12 connects the corresponding pipe to achieve water purification. The control module 161 obtains the monitoring data to assess whether it is necessary to control the distribution component 12 to switch the connected pipe so that the other first purification component 151 or second purification component 152, which is not the current purification component, can take over the water purification work to ensure the stable operation of the circulation system.

[0034] Thus, real-time water quality monitoring can promptly detect or predict coolant deterioration, preventing it from affecting heat dissipation efficiency. The switching design of the dual purification components can alleviate the situation where water quality cannot be guaranteed after the failure of a single component. The control module 161 links heat dissipation management and purification component switching to achieve intelligent control throughout the entire process. While maintaining coolant purity and heat dissipation stability, it helps extend the service life of electronic equipment 20 and purification components, significantly improving the operational reliability, continuity, and intelligence level of the liquid cooling system. In other words, since the cooling component 11 can cool the coolant, the coolant forms a liquid cooling cycle for electronic equipment 20 through the distribution component 12 and the circulation pipe group. The monitoring component 14 monitors the coolant water quality in the circulation pipe in real time. The dual purification components are located in the return pipe 132. The control module 161 links heat dissipation management and distribution component 12 through monitoring data. It can reduce the risk of unreliable coolant water quality purification due to the failure of a single purification component by using the dual purification components. It can switch the current purification component in time to ensure the purification effect of coolant water quality, thus maintaining coolant purity and improving heat dissipation reliability and efficiency.

[0035] Please see Figure 2 , Figure 2 This is a schematic diagram of another embodiment of the heat dissipation device of this application.

[0036] In one embodiment, the liquid supply line 131 includes a liquid supply side and a liquid return side, the liquid supply side and the liquid return side are connected, and the other end of both are connected to the distribution component 12.

[0037] The liquid supply side includes one or more liquid supply branches, which are connected to the inlet 21. The liquid return side includes a first monitoring branch, which is connected to the monitoring component 14.

[0038] The coolant cooled by the cooling component 11 flows into the supply side through the distribution component 12. Part of the coolant flows to the electronic device 20 through the supply branch to dissipate heat from the electronic device 20, and part of the coolant flows into the monitoring component 14 through the first monitoring branch, so that the monitoring component 14 can monitor its water quality.

[0039] The return liquid pipeline 132 includes a first return liquid branch, a second return liquid branch, and a confluence pipeline, with both the first and second return liquid branches connected to the confluence pipeline. The return liquid pipeline 132 also includes a second monitoring branch, through which coolant flowing through the monitoring component 14 for water quality monitoring merges into the return liquid pipeline 132. This is aligned with the flow distribution component 12.

[0040] The first purification component 151 is located in the first return liquid branch, and the second purification component 152 is located in the second return liquid branch. The confluence pipeline has one or more return liquid branches, which are connected to the output port 22.

[0041] Coolant cooled by cooling component 11 flows into distribution component 12, and then is distributed to the supply and return sides of supply pipeline 131. One or more supply branches on the supply side deliver coolant to input port 21 of electronic device 20 for heat dissipation; the first monitoring branch on the return side simultaneously guides a portion of coolant into monitoring component 14 to complete water quality monitoring. Coolant cooled by electronic device 20 is connected to return branch of return pipeline 132 through output port 22. After converging into the confluence pipeline, it flows to either the first return branch equipped with first purification component 151 or the second return branch equipped with second purification component 152. The current purification component completes water purification. Distribution component 12 switches the conducting pipeline according to the instructions of control module 161 to ensure continuous purification and heat dissipation cycle.

[0042] The multiple supply branches on the supply side and multiple return branches on the return side facilitate adaptation to multiple interfaces or multiple electronic devices 20, thereby improving the versatility and heat dissipation functionality of the heat dissipation device. The dual branches of the return pipeline 132 correspond to the dual purification components, and with the switching of the distribution component 12, the situation of coolant quality problems caused by the failure of a single purification component can be reduced. At the same time, the multi-branch layout makes the coolant flow more even, which can improve heat dissipation efficiency and purification effect, and also enhance the adaptability, stability and maintenance flexibility of the heat dissipation device.

[0043] Furthermore, the distribution component 12 includes a first switch K1, a second switch K2, a third switch K3, a fourth switch K4, a fifth switch, a sixth switch K6, and a seventh switch K7.

[0044] The end of the liquid supply side away from the liquid return side is connected to the first switch K1.

[0045] The end of the return liquid side away from the supply liquid side is connected to the second switch K2.

[0046] One end of the confluence pipeline is connected to the first return liquid branch and the second return liquid branch, and the other end is connected to the third switch K3.

[0047] The first return liquid branch is located at the end of the first purification component 151 away from the confluence pipeline and is connected to the fourth switch K4.

[0048] The second return liquid branch is located at the end of the second purification component 152 away from the confluence pipeline and is connected to the fifth switch component K5.

[0049] The sixth switch K6 is connected to the cooling assembly 11, and the seventh switch K7 is connected to the cooling assembly 11.

[0050] When flushing the return line 132, the third switch K3 is turned on.

[0051] Please refer to the following: Figure 2 as well as Figure 3 , Figure 3 This is a schematic diagram of the structure of the first purification component in the heat dissipation device of this application as an embodiment of the current purification component.

[0052] like Figure 3 As illustrated in the example, when the first purification component 151 is the current purification component, the first switch K1, the second switch K2, the fourth switch K4, the sixth switch K6, and the seventh switch K7 are turned on, the third switch K3 and the fifth switch K5 are turned off, the pipeline between the sixth switch K6 and the first switch K1 is connected, the pipeline between the seventh switch K7 and the fourth switch K4 is connected, and the pipeline between the first switch K1 and the second switch K2 is connected.

[0053] Please refer to the following: Figure 2 as well as Figure 4 , Figure 4 This is a schematic diagram of the structure of the second purification component in the heat dissipation device of this application as an embodiment of the current purification component.

[0054] like Figure 4 As illustrated in the example, when the second purification component 152 is the current purification component, the first switch K1, the second switch K2, the fifth switch K5, the sixth switch K6, and the seventh switch K7 are turned on, the third switch K3 and the fourth switch K4 are turned off, the pipeline between the first switch K1 and the second switch K2 is connected, the pipeline between the first switch K1 and the sixth switch K6 is connected, and the pipeline between the fifth switch K5 and the seventh switch K7 is connected.

[0055] The distribution component 12 can switch between different operating conditions through the on / off combinations of seven switches. When the first purification component 151 is working, the first switch K1, the second switch K2, the fourth switch K4, the sixth switch K6, and the seventh switch K7 are turned on, while the third switch K3 and the fifth switch K5 are turned off. The coolant output from the cooling component 11 flows sequentially through the sixth switch K6, the first switch K1, and the supply branch to the electronic device 20. At the same time, part of it is supplied to the monitoring system through the first switch K1, the second switch K2, and the first monitoring branch. The coolant returning from the electronic device 20 flows back to the cooling component 11 through the first return branch, the fourth switch K4, and the seventh switch K7. When the second purification component 152 is working, the fourth switch K4 is turned off and the fifth switch K5 is turned on. The coolant flows back through the second return branch and the fifth switch K5. When flushing the return pipe 132, the third switch K3 can be turned on to flush the return water pipe, thereby reducing the difficulty of cleaning the coolant flow pipe in the circulation pipe and helping to further protect the coolant quality.

[0056] Through the precise division of labor among at least seven switching components, stable switching between the dual purification components and independent operation of the 132 flushing function in the return pipeline can be achieved, further reducing the risk of operational conflicts. When the current purification component is operating or switching between components, the on / off control of the switching components ensures precise coolant flow path, guaranteeing efficient and coordinated heat dissipation, monitoring, and purification. Simultaneously, the flushing function can be performed without disassembling the equipment, reducing maintenance complexity.

[0057] Please continue reading. Figure 2 In one embodiment, the heat dissipation device further includes an airtightness detection component 17, and the circulation pipe assembly further includes an air supply pipe.

[0058] Both ends of the gas supply line are connected to the air tightness detection component 17.

[0059] The gas supply pipeline also includes a gas supply side and a gas return side. The gas supply side is connected to the inlet 21, and the gas return side is connected to the outlet 22.

[0060] The airtightness detection component 17 is connected to the control module 161.

[0061] When an airtightness test is performed, the airtightness detection component 17 performs airtightness detection to obtain airtightness data, and transmits the airtightness data to the control module 161. The control module 161 performs an airtightness assessment based on the airtightness data.

[0062] The working principle of the airtightness detection component 17 will be explained in detail later.

[0063] The air supply pipeline is connected to the airtightness detection component 17 at both ends. The air supply side is connected to the input port 21 of the electronic device 20, and the return air side is connected to the output port 22 of the electronic device 20, forming a complete airtightness detection loop. The airtightness detection component 17 is signal-connected to the control module 161. During airtightness testing, the airtightness detection component 17 starts the detection and generates airtightness data, which is then transmitted to the control module 161. The control module 161 then uses this data to assess whether the airtightness is acceptable. This allows for the construction of an independent detection loop through a dedicated air supply pipeline and detection component, ensuring the accuracy of airtightness testing and reducing the risk of interference from heat dissipation circulation. The control module 161 enables automatic data transmission and intelligent evaluation, reducing manual intervention and improving testing efficiency. Furthermore, it can detect potential pipeline leaks in advance, preventing equipment damage or heat dissipation failure caused by coolant leakage, further enhancing the operational safety and reliability of the liquid cooling system.

[0064] The embodiments of this application also provide a device cluster, and the specific heat dissipation principle is described in detail in conjunction with the specific structure of the device cluster.

[0065] Please refer to the following: Figure 2 as well as Figure 5 , Figure 5 This is a schematic diagram of the structure of an embodiment of the device cluster of this application.

[0066] In one embodiment, the device cluster may include a heat dissipation device as described in any of the above embodiments and a plurality of electronic devices 20.

[0067] The electronic device 20 includes an input port 21 and an output port 22. The input port 21 is connected to the liquid supply line 131, and the output port 22 is connected to the liquid return line 132.

[0068] The coolant, after being cooled by the cooling component 11, flows into the electronic device 20 through the distribution component 12, the supply pipe 131, and the input port 21 of the electronic device 20 to dissipate heat from the electronic device 20. It then flows out through the output port 22 of the electronic device 20 and into the return pipe 132. The return pipe 132 then flows to the current purification component for water purification. The purified coolant then flows through the distribution component 12 to the cooling component 11 for cooling.

[0069] Furthermore, the electronic device 20 may include a liquid cooling plate, which is connected to the input port 21 and the output port 22. Coolant flows into the liquid cooling plate through the input port 21, exchanges heat with the inside of the electronic device 20 within the liquid cooling plate, and then flows to the output port 22 to be cooled by the cooling device.

[0070] The description of the features in the embodiment corresponding to the control module 161 can be found in the relevant description of the embodiment corresponding to the heat dissipation management method, and will not be repeated here.

[0071] The embodiments of this application provide a heat dissipation management method, and the heat dissipation management method is described in detail below in conjunction with the execution flow of the heat dissipation management method.

[0072] Please refer to the following: Figure 2 as well as Figure 6 , Figure 6 This is a schematic diagram of the structure of an embodiment of the device involved in the airtightness test of this application.

[0073] In one embodiment, the heat dissipation device further includes a piping management component 18.

[0074] The pipe connection structure of the pipe management component 18 is as follows: Figure 6 As shown in the diagram. Valves in1 and in2 are air inlet valves, valve in3 is liquid inlet valve, valves out1 and out2 are exhaust valves, and valve out3 is liquid drain valve. When the liquid-cooled server is connected to the gas pipe, valves in3 and out3 are closed; when the liquid-cooled server is connected to the refrigerant pipe, in1, in2, out1, and out2 are closed, and valves in3 and out3 are open. During pressurization, the pipeline management component 18 controls valves in1 and in2 to open and valves out1 and out2 to close; during pressure holding, the pipeline management component 18 controls valves in1 and out1 to open and valves in2 and out2 to close; during exhaust, the pipeline management component 18 controls valves in1 and in2 to close and valves out1 and out2 to open.

[0075] Optionally, the control module 161 can also be connected to the controller of the electronic device 20 to synchronously acquire real-time load data of each node of the electronic device 20, as well as the current ambient humidity and dust concentration parameters fed back by the environmental monitoring module. After extracting the periodic data of the preset period before the current moment, the control module 161, when evaluating the prediction factor, additionally superimposes the load coefficient of the electronic device 20, the ambient humidity correction coefficient, the dust concentration influence coefficient, the original square root of the average variance, and the tuning factor to obtain a comprehensive prediction factor adapted to the high load scenario of the electronic device 20. At the same time, the weight coefficient of the habitual duration is dynamically adjusted based on the cumulative value of the historical prediction deviation. For example, the weight coefficient can be controlled to be higher when the deviation is larger, so as to improve the correction strength. For multiple water quality parameters, in addition to the weighted fusion of maintenance distances by weighting coefficients, a new parameter priority determination is added, such as conductivity having a higher priority than pH value. The maintenance distance of the higher priority parameter is used to calibrate the expected duration. Furthermore, after generating the predicted maintenance time, the control module 161 synchronously sends a pre-start command to the standby purification component to put it into a standby state. When the load of the electronic device 20 is higher than the preset threshold, the preset monitoring time interval and preset cycle duration are automatically shortened to improve the data update frequency.

[0076] This improves the adaptability of the heat dissipation device to the high-density deployment and high load fluctuations of the electronic equipment 20 in this embodiment. The introduction of load and multiple environmental parameters of the electronic equipment 20 makes the comprehensive prediction factor more consistent with the actual operating conditions, significantly improving the accuracy of predicting maintenance times. The habitual duration correction of dynamic weights and parameter priority determination further reduce the cumulative impact of historical deviations and avoid exceeding the standards of key water quality parameters. The pre-start design of the backup purification component reduces the response delay during switching, and the short monitoring interval adapts to the needs of rapid changes in water quality under high load, ensuring that the heat dissipation system is uninterrupted and the water quality is stable and meets the standards when the electronic equipment 20 runs continuously with high computing power. Multi-dimensional optimization reduces the risk of downtime of the electronic equipment 20 due to coolant problems and reduces the frequency of ineffective maintenance, improving the operational availability of the electronic equipment 20 cluster, the adaptability of the heat dissipation system, and the level of precision of intelligent control.

[0077] Please see Figure 7 , Figure 7 This is a flowchart illustrating an embodiment of the heat dissipation management method of this application.

[0078] S101: Acquire monitoring data obtained by the monitoring component from monitoring the coolant in the circulating pipe group; wherein, the monitoring data includes the monitoring values ​​of water quality parameters.

[0079] In this embodiment, the control module of the control component can acquire monitoring data from the monitoring component. This monitoring data is generated by the monitoring component through real-time monitoring of the coolant flowing through the supply and return pipelines. Water quality parameters can include parameters such as conductivity, particle content, and pH value, which directly reflect the purity and heat dissipation suitability of the coolant. This provides objective data support for subsequent water quality trend prediction and purification component control, reducing the risk of water quality judgment errors due to data gaps.

[0080] S102: Predict the maintenance time when the coolant water quality reaches the maintenance threshold by using monitoring data.

[0081] In this embodiment, the control module, based on the acquired water quality parameter monitoring values ​​and combined with the coolant water quality change patterns such as impurity accumulation rate and parameter decay trend, calculates the predicted maintenance time when the coolant water quality reaches the maintenance threshold using algorithms such as time-series prediction models and trend fitting algorithms. The maintenance threshold is a critical water quality value set to ensure heat dissipation efficiency and equipment safety. Predicting this time in advance avoids passively waiting for the water quality to exceed the standard before taking action, thereby allowing buffer time for maintenance or switching of the current purification component, reducing the risk of heat dissipation failure or equipment damage due to sudden coolant failure.

[0082] S103: Generate prompt information and / or switching instructions based on the current time and the predicted maintenance time; wherein, the switching instructions are used to transmit to the control component so that the control component switches the current purification component.

[0083] In this embodiment, the control module can calculate the time difference between the current time and the predicted maintenance time, and generate a corresponding signal according to preset rules. It can achieve accurate prediction of manual maintenance through prompts, and / or ensure continuous water quality compliance through automatic switching commands, reducing the risk of unreliable cooling due to performance degradation of the current purification components, while simultaneously maintaining the operation of the liquid cooling system without interruption, thus balancing maintenance convenience and system stability.

[0084] Therefore, by monitoring the real-time water quality parameters of the coolant in the circulating pipe assembly, and based on this data, combined with water quality change patterns and a preset algorithm, predicting when the coolant water quality will reach the maintenance threshold, and generating reminders for manual maintenance and / or switching commands to switch the purification components based on the time difference between the current time and the predicted maintenance time, intelligent control of water quality and purification components is achieved. The benefits include: real-time monitoring and trend prediction allow for early response, avoiding reactive measures only after water quality exceeds standards; automatic switching between dual purification components allows for uninterrupted operation of the liquid cooling system, ensuring coolant purity and heat dissipation stability; and precise maintenance through reminders reduces manual inspection costs and the risk of equipment damage due to purification component performance degradation, significantly improving the operational reliability, intelligence level, and maintenance convenience of the liquid cooling system.

[0085] The following example illustrates the detailed working principle of heat dissipation management in this embodiment.

[0086] Water quality parameters include at least one of the following: color, residual chlorine, dissolved oxygen, conductivity, pH, and temperature.

[0087] The monitoring component periodically feeds back the water quality parameter values ​​to the control module at preset monitoring intervals, and the control module obtains these water quality parameter values ​​as monitoring data. In other words, it obtains the water quality parameter values ​​periodically fed back by the monitoring component at preset monitoring intervals as monitoring data.

[0088] Obtain the maintenance thresholds for water quality parameters fed back by the monitoring components.

[0089] In other words, the control module can acquire monitoring data of the current time and the preset period duration, and use it as periodic data.

[0090] Evaluate predictive factors that match the fluctuations in water quality parameters within the periodic data.

[0091] Optionally, the average value of water quality parameters over a preset period can be obtained.

[0092] Calculate the average variance corresponding to the average value of the water quality parameters.

[0093] The predictor is obtained by superimposing the square root of the mean variance with the tuning factor. The tuning factor is correlated with the current ambient temperature.

[0094] In other words, the monitoring components periodically collect the water quality parameters of the coolant at preset monitoring intervals as monitoring data, and simultaneously obtain the corresponding water quality parameter maintenance thresholds. The control module extracts the monitoring data within the preset period before the current moment as periodic data. It first calculates the average value and average variance of the water quality parameters within this period, then takes the square root of the average variance and superimposes it with a tuning factor related to the current ambient temperature to obtain a predictive factor for the fluctuation of water quality parameters within the matching periodic data, providing a quantitative basis for subsequent water quality trend prediction. Thus, periodic acquisition of monitoring data ensures data continuity and timeliness, and the prediction factor calculated based on historical periodic data accurately reflects the fluctuation patterns of water quality parameters. The design of the average variance combined with the tuning factor considers both the variation range of the water quality itself and the influence of ambient temperature on water quality, significantly improving the accuracy of the prediction factor. This design lays a reliable data foundation for subsequent prediction of maintenance times, generation of prompts, or switching commands, avoiding untimely maintenance or erroneous switching due to prediction deviations, and further ensuring the stable operation and intelligent control accuracy of the liquid cooling system.

[0095] It is possible to obtain the water quality prediction function and use the prediction factor as the intercept of the water quality prediction function.

[0096] The periodic data is input into the water quality prediction function to obtain the predicted values ​​of water quality parameters.

[0097] Since there are multiple water quality parameters, the difference between the predicted value of each water quality parameter and the maintenance threshold is calculated as its maintenance distance.

[0098] The weighting coefficients of each water quality parameter are obtained, and the maintenance distance is weighted and fused using these coefficients to obtain the expected duration. The expected duration represents the predicted time required for the water quality parameter to change from its monitored value to the maintenance threshold.

[0099] The predicted maintenance time is obtained by overlaying the expected duration, the habitual duration, and the current time. Here, the habitual duration represents the offset of the actual maintenance time of the previous time from its predicted maintenance time.

[0100] In other words, in this embodiment, the monitoring component periodically collects water quality parameter monitoring values ​​at preset intervals as monitoring data, and simultaneously obtains the maintenance thresholds for the water quality parameters. The control module extracts historical monitoring data from the preset period prior to the current moment as periodic data, evaluates the predictive factors matching the water quality fluctuation situation, and uses them as the intercept of the water quality prediction function. The periodic data is then input into the function to obtain the predicted values ​​of the water quality parameters. If there are multiple water quality parameters, the difference between each predicted value and the maintenance threshold is calculated as the maintenance distance. This distance is then weighted and fused using weighted coefficients to obtain the expected duration, i.e., the time it takes for the water quality to change from the current value to the maintenance threshold. The expected duration, the habitual duration, and the current moment are superimposed to finally determine the predicted maintenance time. Thus, periodic data collection ensures the continuous capture of water quality change trends, the predictive factors, combined with water quality fluctuation situations and multi-parameter weighted fusion, consider the importance of different indicators, and the habitual duration correction can compensate for historical prediction deviations and user maintenance habits. Multi-dimensional optimization makes the predicted maintenance time more accurate. It can accurately predict the critical time for coolant water quality to meet standards in advance, providing sufficient buffer for the switching of purification components or manual maintenance, avoiding heat dissipation failure or equipment damage caused by excessive water quality, while reducing unnecessary component switching and manual inspection, and significantly improving the intelligent control accuracy, operational stability and maintenance economy of the liquid cooling system.

[0101] Get the preset prompt duration.

[0102] A prompt message is generated when the difference between the current time and the predicted maintenance time is less than a preset prompt duration. This prompt message indicates that the current purification component can be switched.

[0103] A switching instruction is generated in response to the current time matching the predicted maintenance time.

[0104] Therefore, this embodiment utilizes water quality monitoring terminals deployed in the secondary circulation system to automatically and periodically collect water quality parameters such as residual chlorine, dissolved oxygen, conductivity, and pH (hydrogen ion concentration). By predicting water exchange time through a linear regression algorithm, the maintenance difficulty of manual periodic water quality inspection can be reduced. It can also automatically adjust the water exchange frequency on the secondary side to reduce the pressure on the water purification system, thereby improving the effective utilization efficiency of human and water resources and reducing production costs.

[0105] In layman's terms, the monitoring component can periodically push the monitoring values ​​of n water quality parameters to the control module, i.e., X = {X1, X2, ..., X...} n The monitoring component can push maintenance thresholds for various water quality parameters to the control module, i.e., Th = {Th1, Th2, ..., Th}. nThe control module uses moving average variance to predict the degree of trend change, which is beneficial for observing the changing trends of water quality parameters. For example, for a certain water quality parameter X... i You can select parameter collection values ​​for a certain period (such as 3 days, 7 days, etc.) and calculate their moving average as the average value using a formula such as the following:

[0106] Formula 1-1

[0107] Among them, MA i X represents the i-th water quality parameter. i The average value; X i,t-j This represents the collected value in the tjth period, and N is the moving average period (note that n represents the number of water quality parameters, and N represents the moving average period, i.e., the preset period length).

[0108] The average variance of water quality parameters can be calculated based on the average value using the following formula:

[0109] Formula 1-2

[0110] Among them, s i 2 Let represent the average variance of the i-th water quality parameter.

[0111] The control module uses a linear regression algorithm to predict water quality parameters. For water quality parameter X... i The corresponding predicted value y i It can be expressed by the following formula:

[0112] Formula 1-3

[0113] Where, ε i This represents the predictor.

[0114] Equations 1-3 can be represented as Y = Xβ + ε. The solution for β can be obtained using methods such as least squares, as illustrated in the following example:

[0115] β = (X) T X) -1 X T Y formula 1-4

[0116] Where T represents transpose.

[0117] ε i The calculation method can be illustrated in the following formula:

[0118] Formula 1-5

[0119] Where ω(x) represents the tuning factor related to ambient temperature.

[0120] The more liquid-cooled servers connected to the aging test, the longer the water purification system's filtration devices are used, and the closer the water quality parameters are to the maintenance standard threshold. The closer they are to the maintenance standard threshold, the more maintenance is needed for the circulating or storage water purification system. The control module can calculate the weighted Euclidean distance between the predicted water quality parameters and the maintenance standard threshold to measure the degree of maintenance required for the water purification system, thereby determining the early warning maintenance time.

[0121] In other words, the predicted values ​​for each water quality parameter If the corresponding weight coefficients are λ={λ1,λ2,…,λ n The weighted Euclidean distance between the predicted water quality parameters and the maintenance standard threshold can be calculated using the following formula:

[0122] Formula 1-6

[0123] Where d represents the expected duration.

[0124] Specifically, if the weighting coefficient λ of a certain water quality parameter k A value of 0 indicates that the water quality parameter X is 0. k It does not participate in maintenance prediction decisions. Then, based on decision 'd' regarding whether to initiate maintenance alerts, the predicted maintenance time is obtained by overlaying the expected duration, the habitual duration, and the current time. For example, the habitual duration can be the corrected distance between the predicted maintenance date corresponding to the last alert time and the actual maintenance date. That is, the formula for calculating the predicted maintenance time can be illustrated as follows:

[0125] T = α(d) + T0 (Equation 1-7)

[0126] Where T represents the predicted maintenance time, T0 represents the habitual duration, and α(d) represents the expected duration.

[0127] The following examples illustrate the above heat dissipation management methods with specific time settings.

[0128] The water quality monitoring and data acquisition system pushes the latest measurement data of turbidity, conductivity, and pH value to the control module every morning at 8:00 AM. And set the maintenance standard threshold for the corresponding parameters to Th={5,80,8}. Select a moving average period of 5 days, i.e., N=5, then its moving average line is... , where X i,t-j For X i The collected values ​​(i=1,2,3) on day tj. Therefore, its moving average variance is... Additionally, for the tuning factor of ambient temperature, the northern factory can take... .

[0129] The weighting coefficients for water quality parameters are simplified to λ={1,1,1}, and the weighted Euclidean distance between the predicted value and the maintenance standard threshold is: For T = α(d) + T0 and T0 = [μ·Δt] (0 ≤ μ ≤ 1), the warning is initiated when 0 ≤ d ≤ 10. Taking α(d) = [d] and μ = 0.5, the warning time is... If the current date is CurData, then the predicted maintenance date PreData = CurData + T.

[0130] When PreData < CurData, the control module can remind maintenance personnel of the predicted maintenance date, allowing them to manually switch the primary and backup water purification systems in advance for maintenance. When PreData = CurData, the control module will notify the CDU to automatically switch the secondary-side return water loop, thus completing the primary / backup switch between the circulating water purification system and the reserve water purification system (backup becomes primary, primary becomes backup), and then notify maintenance personnel to maintain the switched-off backup system. During the primary / backup switch of the secondary-side return water loop, whether manual or automatic, the control module will notify the gas-liquid pipeline switching control system to suspend gas-liquid pipeline operations, as described above. Since the return water loop switch is usually relatively fast, its impact on the gas-liquid pipeline switch can be considered small; therefore, the two can be considered to operate independently, thus achieving uninterrupted maintenance.
