Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of load test box internal monitoring, in particular to a modular liquid-cooled load test box and a detection method thereof. BACKGROUND

[0002] A load test box is a test device used to simulate load conditions under real working conditions, mainly used to verify the performance, reliability and durability of electronic products, mechanical parts, energy systems, etc. under specific loads. It simulates stress conditions in actual use environment by precisely controlling electrical, thermal, mechanical or hydraulic load parameters, helping researchers to find design defects and optimize product performance.

[0003] Publication No. CN120216296A discloses a case internal temperature intelligent monitoring system, characterized in that the system comprises: a temperature acquisition synchronization module based on case internal monitoring data, extracts real-time temperature values of key areas inside the case, sorts time stamps of sensor data in order, collects temperature data, and filters abnormal data whose time interval exceeds the sampling period setting range, generates a case internal temperature time sequence, an environmental difference analysis module calls the case internal temperature time sequence, identifies the difference between node temperature and environmental temperature, filters nodes exceeding the synchronous analysis benchmark threshold, extracts difference amplitude and time distribution characteristics, generates a case temperature difference distribution table, a cold control response determination module based on the case temperature difference distribution table extracts node temperature difference peaks and fluctuation rates, detects whether the difference rising rate exceeds the cold control trigger benchmark, filters trigger nodes, and labels corresponding fan numbers and control unit indexes, generates a case cold control response trigger list, and a heat source positioning identification module calls the case cold control response trigger list, extracts abnormal node positions and adjacent node temperature values, and the system realizes heat anomaly and energy efficiency trend evaluation. However, in actual use, the device and the existing equipment mostly adopt the way of pump linkage liquid cooling water circulation to cool the load box. However, due to the relatively violent water impact force at the output end of the pump, the existing equipment usually adopts the way of clamp or flange plate to fix. However, the special setting of the liquid cooling water circulation system is that the cold water enters the load box to absorb heat and cool, and the water heated after absorbing heat is transported to the pump again after cooling, which also causes that the output end of the pump can only contact the cold water, so that the sealing piece (installed at the clamp or flange plate) at the connection between the output end of the pump and the pipeline cannot continue to maintain sealing due to thermal expansion and cold contraction volume reduction, so that the connection between the output end of the pump and the pipeline is prone to liquid leakage. The existing liquid leakage monitoring system can only detect the video at the output end of the pump to analyze when the liquid leaks. This method can only find the liquid when it drops. Water seeping into the power supply / mainboard can cause instantaneous short circuit. The device cannot give timely warning before the liquid leaks. The existing equipment has further space for improvement in the effect of preventing liquid leakage of the load box. SUMMARY

[0004] In view of the defects of the prior art, the application provides a modular liquid cooling load test box and a detection method thereof, which has the advantages of improving the effect of preventing liquid leakage of the load box, facilitating user use, and the like.

[0005] To achieve the above-mentioned purpose, the application provides the following technical scheme: a modular liquid cooling load test box and a detection method thereof, comprising: a control center, a load box body, a plug-in interface, a first linear drive assembly, a push rod, a mounting block, an adsorption strip, a conveying box, a first conveying pipe, a cooling box, a second conveying pipe, a suction pipe, a load body, a cooling pipe, a heating pipe, a pump, an accumulated liquid bin, a power chamber, a second linear drive assembly, a sealing plate, a top plate, and a compensation cavity.

[0006] The position and connection relationship of each structure are as follows: a modular liquid cooling load test box and a detection method thereof, comprising a control center for controlling the start and stop of the load test box, a load body for load testing a server, a detection device, a pump, and a cooling box, S100, the server is electrically connected with the load body, the load body performs load testing on the server, the control center monitors the temperature inside the load body, and the control center starts the pump to perform liquid cooling on the load body when the load body is heated; S200, the detection device detects each item of data at the output end of the pump and uploads the detection result to the control center; S300, the control center analyzes the model according to the detection result to determine whether the output end of the pump leaks, and timely takes measures to remedy; S400, the control center continuously optimizes the analysis model according to the detection result and long short-term memory recursion.

[0007] S200, the detection device is composed of an air pressure sensor, a flow meter and a liquid level detector, the air pressure sensor and the flow meter are arranged at the output end of the pump machine, and the liquid level detector is arranged in the interior of the cooling box. The pump machine cooperates with the cooling box to cool the load body when the load body tests the server. The air pressure sensor and the flow meter respectively detect the air pressure and the water flow data at the output end of the pump machine in real time. The liquid level detector detects the liquid level data in the interior of the cooling box in real time, and uploads the detected air pressure change data, water flow change data and liquid level change data to the control center for analysis and processing.

[0008] S300, a buzzer is fixedly connected in the interior of the control center. The analysis model in the interior of the control center performs data cleaning processing on the uploaded air pressure change data, water flow change data and liquid level change data, including processing missing values, deleting repeated data and modifying data formats. The processed air pressure change data, water flow change data and liquid level change data are subjected to feature selection analysis processing. The analysis model analyzes that the air pressure at the output end of the pump machine decreases, the water flow decreases and the liquid level decreases, that is, the pump machine output end appears a liquid leakage risk.

[0009] A threshold value is set in the analysis model. The threshold value is the maximum air pressure, the maximum water flow and the maximum liquid level data when the pump machine output end appears liquid leakage. The analysis model compares and analyzes the air pressure change data, the water flow change data and the liquid level change data collected by the detection device with the threshold value. When the air pressure change data, the water flow change data and the liquid level change data are all less than the threshold value, the air pressure decrease and the water flow decrease at the output end of the pump machine are caused by the thermal expansion and cold contraction phenomenon, and the device does not perform early warning processing. When the air pressure change data, the water flow change data and the liquid level change data are greater than the threshold value, the pump machine output end appears liquid leakage. The detection device continues to detect the air pressure change data and the water flow change data at the output end of the pump machine. When the air pressure gradually decreases, the liquid leakage at the output end of the pump machine is not serious. The control center uses the first measure to avoid liquid leakage and timely early warning by using the liquid accumulation bin. The load body can continue to test the server under the first measure. When the air pressure decreases in a short time and returns to the normal air pressure, the liquid leakage at the output end of the pump machine is serious. The output end of the pump machine is connected with the outside, causing the air pressure to return to normal. The liquid leakage is serious. The control center uses the second measure, that is, the pump machine reversely draws water back into the cooling box, and the liquid accumulation bin collects the liquid leakage. The control center transmits an electric signal to the buzzer for early warning. In this case, the load body cannot continue to test the server.

[0010] S300, the air pressure change data, water flow change data, liquid level change data detected by the detection device in real time can be classified by time into T1 time period data S1, T2 time period data S2, and T3 time period data S3, and the control center constructs a time sequence prediction engineering model according to the T1 time period data S1, the T2 time period data S2, and the T3 time period data S3, and when the air pressure change data, the water flow change data, and the liquid level change data are all less than the threshold value in S200, that is, when the air pressure and the water flow at the output end of the pump are reduced, the water thermal expansion and cold contraction phenomenon occurs, the time sequence prediction engineering model predicts and analyzes the data at the output end of the pump in the future, and when the prediction result is greater than the threshold value, that is, the pump will leak in the future, the control center selects the first measure or the second measure according to the prediction result and gives an early warning, and when the prediction result is less than the threshold value, that is, the pump will not leak in the future, the load main body can continuously test the server.

[0011] S400, in the case that the prediction result actually collected air pressure change data, water flow change data, liquid level change data difference is large, then the collected data is used as training data to train the prediction model, and the difference between the prediction result of the prediction model and the collected data is continuously reduced in the long run, so as to improve the accuracy of the device prediction and ensure the normal operation of the device.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

S200, the detection device detects various data at the output end of the pump 24 and uploads the detection results to the control center 1; S300, the internal analysis model of the control center 1 determines that there is leakage at the output end of the pump 24 based on the detection results, and takes timely remedial measures; S400, the control center 1 continuously optimizes the analysis model based on the detection results and the long-short-term memory recursion; In real life, the leakage monitoring system can usually only perform video detection and analysis on the output end of the pump 24 when the leakage occurs. This method will detect the leakage when the liquid has already dripped, and the water seeping into the power supply / mainboard will cause a transient short circuit. The device cannot issue a timely warning before the leakage occurs. The present invention discloses a modular liquid-cooled load test box and a detection method thereof, which can solve the above problem through the following steps: See also Figures 1 to 2 , further in the above description, S200, the detection device is composed of an air pressure sensor, a flow meter and a liquid level detector.

The air pressure sensor and the flow meter respectively detect the air pressure and water flow data at the output end of the pump 24 when the pump 24 is turned on in real time. The liquid level detector detects the liquid level height data inside the cooling box 221 in real time, and uploads the detected air pressure change data, water flow change data, and liquid level height change data to the control center 1 for analysis and processing; The device performs real-time detection of the air pressure and water flow data at the output end of the pump 24 when it is turned on, and the liquid level data inside the cooling box 221. The air pressure and water flow data are used to preliminarily determine whether there is leakage at the output end of the pump 24. However, there are also cases where the air pressure and water flow change due to thermal expansion and contraction of water. The detection of the liquid level can monitor the total amount of water. However, when cold water absorbs heat and becomes hot water, and the water temperature rises from low temperature to above 60°C, its air solubility decreases by 52%, and the release of dissolved gas causes the liquid level to drop. The system further improves the detection accuracy of leakage by collecting and analyzing the three data together, avoiding the situation where the device makes a misjudgment when only a single data is used for judgment, thereby improving the anti-leakage monitoring effect of the load box.

Please refer to Figures 5 to 12Further in the foregoing description, the top of the control center 1 is fixedly connected with a load box 2, the inside of the load box 2 is fixedly connected with a temperature sensor, the top side inner wall of the load box 2 is fixedly connected with a first linear drive assembly 21, the first linear drive assembly 21 is specifically a hydraulic cylinder, the bottom side inner wall of the load box 2 is fixedly connected with a load body 23, the load body 23 is composed of a plurality of resistance modules and the resistance modules can be mutually stacked and clamped, the front end of the load body 23 at the bottom side is fixedly connected with a cooling pipe 230 and a heating pipe 231 at both sides, respectively, one end of the cooling pipe 230 and the heating pipe 231 close to the resistance module is fixedly connected with a distribution pipe, the other end of the distribution pipe is fixedly connected with the resistance module and the connection between the distribution pipe and the resistance module is fixedly connected with an electric valve, a pump machine 24 is arranged at the front end of the cooling pipe 230, the output end of the pump machine 24 is fixedly connected with the cooling pipe 230 and the outer surface of the connection between the output end of the pump machine 24 and the cooling pipe 230 is provided with an accumulated liquid bin 25, the accumulated liquid bin 25 is arranged in an arc shape, the front end and the rear end of the accumulated liquid bin 25 are fixedly connected with a power chamber 250 at both sides, the inside of the power chamber 250 is fixedly connected with a second linear drive assembly 251, one end of the two second linear drive assemblies 251 close to the symmetry plane is fixedly connected with a sealing plate 252 and the sealing plate 252 is arranged inside the accumulated liquid bin 25, the sealing plate 252 is arranged in an arc shape and the top of the sealing plate 252 is fixedly connected with a top plate 253 at both sides, the top of the accumulated liquid bin 25 is fixedly connected with a compensation cavity 254 at both sides; Under normal circumstances, the server is electrically connected with the load body 23 through the plug-in interface 20, when the temperature sensor detects that the load body 23 is heated, the control center 1 starts the pump machine 24 to transport the cooling in the cooling box 221 to each resistance module through the cooling pipe 230 and the plurality of distribution pipes at the position through the extraction pipe 223, then the hot water after heat absorption is transmitted to the liquid inlet groove in the inside of the conveying bin through the heating pipe 231, the first conveying pipe 220, the liquid inlet groove in the inside of the conveying bin and the second conveying pipe 222, and then the hot water is transported into the cooling box 221 for cooling to achieve circulation, when the control center 1 adopts the first measure, the control center 1 starts the four second linear drive assemblies 251, the four linear drive assemblies drive the two sealing plates 252 to move linearly to each other, the two sealing plates 252 clamp and fix the bottom side of the connection between the output end of the pump machine 24 and the cooling pipe 230, at this time, the accumulated liquid bin 25, the four top plates 253 and the two sealing plates 252 form a closed space, under the influence of gravity, the leaked liquid at the pump machine 24 and the cooling pipe 230 flows down through the bottom side, and the leaked liquid flows into the accumulated liquid bin 25 for collection, in the present application, the accumulated liquid bin 25 is arranged in an arc shape so that the leaked liquid can be concentrated in the inside center of the accumulated liquid bin 25, which is convenient for subsequent treatment of the leaked liquid; Please refer to Figures 5 to 12Further in the foregoing description, the inner wall of the conveying box 22 is provided with a liquid inlet groove, one side of the conveying box 22 is fixedly connected with a first conveying pipe 220, the other end of the first conveying pipe 220 is fixedly connected with the temperature rising pipe 231, a cooling box 221 is arranged at the rear end of the conveying box 22, and a second conveying pipe 222 is fixedly connected between the conveying box 22 and the cooling box 221, the cooling box 221 is fixedly connected to the rear end inner wall of the load box 2, the inner wall of the cooling box 221 is fixedly connected with a cooler, the other side of the cooling box 221 is fixedly connected with a suction pipe 223, the other end of the suction pipe 223 is fixedly connected with the input end of the pump 24, the bottom output end of the linear drive assembly is fixedly connected with a push rod 210, the push rod 210 penetrates through the conveying bin and extends to the bottom outside of the conveying bin, the extension part of the push rod 210 is fixedly connected with a mounting block 211, the bottom of the mounting block 211 is fixedly connected with an adsorption strip 212, and the adsorption strip 212 is specifically a porous material of silicone rubber; When the liquid collection bin 25 is collected to a certain degree, the user can open the first linear drive assembly 21 through the control center 1, the first linear drive assembly 21 drives the mounting block 211 and the two adsorption strips 212 to move downward through the push rod 210, the adsorption strips 212 move and enter the liquid collection bin 25 through the two compensation cavities 254, and since the adsorption strips 212 are made of a porous material of silicone rubber and have a certain deformation recovery ability, the two adsorption strips 212 are deformed along the arc-shaped structure of the liquid collection bin 25 and extend to the inner center of the liquid collection bin 25, so that the liquid leakage in the liquid collection bin 25 is adsorbed and treated, the two compensation cavities 254 are used for compensating the rising height of the liquid leakage when the adsorption strips 212 extend into the liquid collection bin 25, so that the adsorption strips 212 do not overflow from the top of the liquid collection bin 25 due to the rising of the liquid leakage, compared with the existing equipment which adopts the mode of connecting an outer pipe with an inner pipe and connecting the outer pipe with the liquid leakage inner pipe to transport water to avoid liquid leakage, the structure of the present application is more convenient for liquid discharge while avoiding liquid leakage, and is also more convenient when the pump 24 needs to be disassembled due to failure, thereby improving the liquid leakage prevention effect of the load box; Please refer to Figures 5 to 12 Further in the foregoing description, the load body 23 further comprises a plug-in interface 20 fixedly connected to the front end surface of the load body 23, and the plug-in interface 20 is electrically connected with the load body 23; In the above-mentioned step, when the first linear drive assembly 21 drives the adsorption strip 212 to reset, it returns to the conveying chamber. Since the liquid inlet groove inside the conveying chamber always conveys hot water after heat absorption, its temperature is usually between 60-80℃. When the hot water is conveyed to the second conveying pipe 222 through the liquid inlet groove, the inside of the conveying chamber always remains in a heated state, and the adsorption strip 212 that leaks liquid can slowly heat and dry inside it, so that the next time the adsorption strip 212 can normally adsorb the leaked liquid without being saturated. The device can continuously process the leaked liquid, improving the anti-leakage effect of the load box. The device uses multiple resistance modules to form the load body 23. On the one hand, when a single resistance module is damaged, it is convenient to repair, and the entire load body 23 does not need to be replaced, saving resources. On the other hand, the linkage of multiple resistance modules with the distribution pipe makes the liquid cooling and heat dissipation effect of the device more significant than that of a single pipe. Please refer to Figures 1 to 4 Further in the above description, S300, the real-time detected air pressure change data, water flow change data, and liquid level change data can be classified by time into T1 time period data S1, T2 time period data S2, and T3 time period data S3. Control center 1 constructs a time sequence prediction engineering model according to T1 time period data S1, T2 time period data S2, and T3 time period data S3. When the air pressure change data, water flow change data, and liquid level change data are all less than the threshold value in S200, it means that the air pressure and water flow at the output end of the pump 24 are reduced, which is caused by the thermal expansion and cold contraction of water. The time sequence prediction engineering model predicts and analyzes the data at the output end of the pump 24 in the future. When the prediction result is greater than the threshold value, it means that the pump 24 will leak in the future. At this time, the control center 1 selects to use the first measure or the second measure according to the prediction result and gives an early warning. When the prediction result is less than the threshold value, it means that the pump 24 will not leak in the future. The load body 23 can continue to load test the server. The device uses a time sequence prediction engineering model to predict when water appears thermal expansion and cold contraction. The sealing piece (installed at the clamp or flange) at the connection between the output end of the pump 24 and the pipe cannot continue to maintain sealing due to thermal expansion and cold contraction volume reduction, so the device can predict and prevent the connection between the output end of the pump 24 and the pipe from leaking, improving the anti-leakage monitoring effect of the load box. Please refer to Figure 1Further in the above description, S400, in the case where the predicted result is actually collected pressure change data, water flow change data, liquid level change data, the difference is large, then the current collection data is used as training data to train the prediction model, and the difference between the prediction result of the prediction model and the collection data is continuously reduced in the long run to improve the accuracy of the device prediction and ensure the normal operation of the device.

The analysis model compares and analyzes the air pressure change data, water flow rate change data and liquid level height change data collected by the detection device with the threshold value. When the air pressure change data, water flow rate change data and liquid level height change data are all less than the threshold value, that is, the air pressure and water flow rate at the output end of the pump (24) decrease due to the thermal expansion and contraction of water, the device does not perform early warning processing. When the air pressure change data, water flow rate change data and liquid level height change data are greater than the threshold value, that is, leakage occurs at the output end of the pump (24), the detection device continues to detect the air pressure change data and water flow rate change data at the output end of the pump (24).

When the air pressure drops in a short time and returns to the normal pressure, the leakage at the output end of the pump (24) is serious. The output end is connected to the outside world, causing the air pressure to return to normal. The leakage is more serious. The control center (1) activates the second measure, that is, the pump (24) reverses to pump water back into the cooling box (221). At the same time, the liquid storage tank (25) collects the leakage. The control center (1) transmits an electrical signal to the buzzer for warning. When the detection device detects that the air pressure at the output end of the pump (24) drops in a short time and returns to the normal pressure, the load body (23) cannot continue to perform load testing on the server.

The control center (1) constructs a time series prediction engineering model based on the data S1 within the T1 time period, the data S2 within the T2 time period, and the data S3 within the T3 time period. In step S200, when the air pressure change data, the water flow change data, and the liquid level change data are all less than the threshold value, that is, at this time, the air at the output end of the pump (24) is When the pressure reduction and water flow reduction are caused by the phenomenon of water thermal expansion and contraction, the time series prediction engineering model predicts and analyzes the data at the output end of the pump (24) in the future. When the prediction result is greater than the threshold, the pump (24) will leak in the future. At this time, the control center (1) selects to enable the first measure or the second measure according to the prediction result and issues an early warning. When the prediction result is less than the threshold, the pump (24) will not leak in the future, and the load body (23) can continue to perform load testing on the server.
