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 equipment used for simulating load conditions under real working conditions, mainly used for verifying 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 collection 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 set range of sampling period, 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 threshold, extracts the difference amplitude and time distribution characteristics, and 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; 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.

[0004] However, in practical use, this device and existing equipment mostly use a pump-driven liquid-cooled water circulation method to cool the load tank. However, due to the strong water impact force at the pump's output end, existing equipment usually uses clamps or flanges for fixation. However, the special configuration of the liquid-cooled water circulation system is that cold water enters the load tank to absorb heat and cool down. After absorbing heat and heating up, the water is cooled down and then transported back to the pump. This means that the pump's output end usually only comes into contact with cold water. As a result, the sealing strip (installed at the clamp or flange) at the connection between the pump's output end and the pipeline reduces in volume due to thermal expansion and contraction and can no longer maintain a seal. This makes the connection between the pump's output end and the pipeline prone to leakage. Existing leakage detection systems can usually only perform video detection and analysis at the pump's output end to detect leakage. By the time leakage is detected, the liquid has already dripped, and water seeping into the power supply / main board can cause a momentary short circuit. The device cannot provide timely warnings before leakage. There is room for further improvement in the leakage prevention detection effect of existing equipment for the load tank.

Obviously, the described embodiments are only part of the embodiments of the application, rather than all the embodiments of the application. Based on the embodiments in the application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the application.

[0037] 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;

[0038] S300, the internal analysis model of the control center 1 judges that the output end of the pump 24 appears liquid leakage according to the detection results, and timely measures are taken for remediation;

[0039] S400, the internal analysis model of the control center 1 is continuously optimized according to the detection results and long and short term memory recursion;

[0040] In actual life, the liquid leakage monitoring system can only perform video detection on the output end of the pump 24 and analyze the liquid leakage, and the liquid has already dropped when the liquid leakage is found, and water seeping into the power supply / mainboard can cause instantaneous short circuit, so that the device cannot timely give a warning before the liquid leakage;

[0041] The application discloses a modular liquid cooling load test box and a detection method thereof, which can solve the above problems through the following steps.

[0042] Please refer to 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 are arranged at the output end of the pump 24, and the liquid level detector is arranged in the internal of the cooling box 221; the pump 24 and the cooling box 221 cooperate to cool the load body 23 when the load body 23 performs load testing on the server, the air pressure sensor and the flow meter respectively perform real-time detection on the air pressure and water flow data at the output end of the pump 24 when the pump 24 is started, the liquid level detector performs real-time detection on the liquid level data in the internal of the cooling box 221, and the detected air pressure change data, water flow change data and liquid level change data are uploaded to the control center 1 for analysis and processing;

[0043] The device detects the air pressure and water flow data at the output end of the pump 24 when it is turned on, the liquid level data inside the cooling tank 221, wherein the air pressure and water flow data are used to preliminarily judge whether the pump 24 output end leaks, but there are also cases of water thermal expansion and cold contraction leading to changes in air pressure and water flow, and the liquid level detection can monitor the total amount of water, but at the same time, when cold water absorbs heat to become hot water, the water temperature rises from low temperature to above 60°C, the air solubility decreases by 52%, and the release of dissolved gas causes the liquid level to drop. The system collects and analyzes the three data to further improve the detection accuracy of the leakage condition, avoids the misjudgment of the device when only a single data is used to judge, and improves the anti-leakage monitoring effect of the load tank.

[0044] Please refer to Figures 1 to 3 Further in the above description, S300, the control center 1 is fixedly connected with a buzzer inside, the analysis model inside the control center 1 carries out data cleaning processing according to the uploaded air pressure change data, water flow change data and liquid level change data, including processing missing values, deleting duplicate data and modifying data format, and carries out feature selection analysis processing on the processed air pressure change data, water flow change data and liquid level change data. The analysis model analyzes the air pressure reduction, water flow reduction and liquid level reduction at the output end of the pump 24, indicating that there is a risk of leakage at the output end of the pump 24;

[0045] Please refer to Figures 1 to 3Further in the above description, the analysis model internally sets a threshold value, which is the highest gas pressure, maximum water flow and maximum liquid level data when liquid leakage occurs at the output end of the pump 24, and the analysis model compares and analyzes the gas pressure change data, water flow change data and liquid level change data collected by the detection device with the threshold value. When the gas pressure change data, water flow change data and liquid level change data are all less than the threshold value, it means that the decrease in gas pressure and water flow at the output end of the pump 24 is caused by the thermal expansion and cold contraction phenomenon, and the device does not take warning processing. When the gas pressure change data, water flow change data and liquid level change data are greater than the threshold value, it means that liquid leakage occurs at the output end of the pump 24, and the detection device continues to detect the gas pressure change data and water flow change data at the output end of the pump 24. When the gas pressure is gradually decreasing, the liquid leakage at the output end of the pump 24 is not serious, and the control center 1 uses the first measure to avoid liquid leakage and timely warning by using the liquid accumulation bin 25. Under the first measure, the load main body 23 can still continue to test the load of the server. When the gas pressure decreases in a short time and returns to the normal gas pressure, the liquid leakage at the output end of the pump 24 is serious, and the output end is connected with the outside world, which causes the gas pressure to return to normal. The liquid leakage is serious, and the control center 1 uses the second measure, that is, the pump 24 reverses to pump the water back to the cooling box 221, and the liquid accumulation bin 25 collects the liquid leakage. The control center 1 transmits an electric signal to the buzzer for warning. Under this condition, the load main body 23 cannot continue to test the load of the server;

[0046] 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;

[0047] Generally, the server is electrically connected with the load body 23 through the plug 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 to the cooling box 221 to be cooled 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;

[0048] Please refer toFigures 5 to 12 Further in the above description, the inner side of the load box 2 is fixedly connected with a conveying box 22, and the conveying box 22 is arranged at the top of the load body 23. An 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 a 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 cooling box 221 and the conveying box 22. The cooling box 221 is fixedly connected to the rear end inner wall of the load box 2. The inner side 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 outer side 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. The adsorption strip 212 is specifically a porous material of silicone rubber.

[0049] When the liquid collection bin 25 is collected to a certain extent, 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. 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 deform along the arc-shaped structure of the liquid collection bin 25 and extend to the inner center of the liquid collection bin 25 to adsorb the leaked liquid. The two compensation cavities 254 are used to compensate for the rising height of the leaked liquid when the adsorption strips 212 extend into the liquid collection bin 25, so as to avoid the situation that the leaked liquid rises to overflow from the top of the liquid collection bin 25 after the adsorption strips 212 extend in. 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 inner pipe to transport water to avoid leakage, the structure of the present application is more convenient for liquid discharge while avoiding liquid dripping. In addition, when the pump 24 fails and needs to be disassembled, it is also more convenient. The effect of preventing liquid leakage of the load box is improved.

[0050] Please refer to Figures 5 to 12 Further in the above description, the load body 23 further comprises a plug-in interface 20 fixedly connected to the front end surface of the load body 23. The plug-in interface 20 is electrically connected with the load body 23.

[0051] 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 adsorption strip 212 can normally adsorb the leaked liquid next time without being saturated. The device can continuously process the leaked liquid, improving the anti-leakage effect of the load box.

[0052] 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.

[0053] Please refer to Figures 1 to 4 In the above description, further, S300, the real-time detected air pressure change data, water flow change data, and liquid level change data of the detection device can be classified by time into T1 time period data S1, T2 time period data S2, and T3 time period data S3. The 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, that is, when the air pressure and water flow at the output end of the pump 24 decrease, it 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, that is, 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, that is, the pump 24 will not leak in the future. The load body 23 can continue to load test the server.

[0054] 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 that the device can predict and prevent when the connection between the output end of the pump 24 and the pipe is prone to leaking, improving the anti-leakage monitoring effect of the load box.

[0055] 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.

[0056] While embodiments of the present application have been shown and described with reference to particular embodiments thereof, it will be understood by those skilled in the art that various changes in form and details can be made therein without departing from the spirit and scope of the application. The scope of the application is defined by the appended claims and their equivalents.

A testing method for a modular liquid-cooled load test chamber, comprising a control center (1) for controlling the start and stop of the load test chamber, a load body (23) for performing load testing on a server, a testing device, a pump (24), and a cooling box (221), characterized in that: S100, the server is electrically connected to the load body (23), the load body (23) performs load testing on the server, the control center (1) monitors the internal temperature of the load body (23), and when the load body (23) heats up, the control center (1) turns on the pump (24) to perform liquid cooling on the load body (23); 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) judges that there is leakage at the output end of the pump (24) based on the detection results, and takes timely measures to remedy the situation; S400, the control center (1) continuously optimizes the analysis model based on the detection results and long short-term memory recursion; S200, the detection device consists of a pressure sensor, a flow meter and a liquid level detector. The pressure sensor and the flow meter are both located at the output end of the pump (24), and the liquid level detector is located inside the cooling box (221). The pump (24) and the cooling box (221) work together to cool the load body (23) when the server is under load test. The pressure sensor and the flow meter respectively detect the pressure and water flow data at the output end of the pump (24) 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 pressure change data, water flow change data and liquid level height change data to the control center (1) for analysis and processing. S300, the internal fixed connection of the control center (1) is a buzzer. The internal analysis model of the control center (1) performs data cleaning processing based on the uploaded air pressure change data, water flow change data, and liquid level change data, including processing missing values, deleting duplicate data, modifying data format, and performing feature selection analysis processing on the processed air pressure change data, water flow change data, and liquid level change data. The analysis model analyzes that when the air pressure, water flow, and liquid level at the output end of the pump (24) decrease, there is a risk of leakage at the output end of the pump (24). The analysis model sets a threshold, which is the highest air pressure, maximum water flow, and maximum liquid level data when leakage occurs at the output end of the pump (24). The analysis model compares the air pressure change data, water flow change data, and liquid level change data collected by the detection device with the threshold. When the air pressure change data, water flow change data, and liquid level change data are all less than the threshold, that is, when the air pressure and water flow at the output end of the pump (24) decrease, it is caused by the thermal expansion and contraction of water, and the device does not make a warning. When the air pressure change data, water flow change data, and liquid level change data are greater than the threshold, that is, when leakage occurs at the output end of the pump (24), the detection device continues to detect the air pressure change data and water flow change data at the output end of the pump (24). When the air pressure gradually decreases, the pump (24) will leak. 4) The leakage at the output end is not serious. The control center (1) activates the first measure, using the liquid collection tank (25) to prevent the leakage from dripping and to provide timely warning. Under the first measure, the load body (23) can still continue to perform load testing on the server. When the air pressure drops and returns to normal air pressure in a short time, the leakage at the output end of the pump (24) is serious. Its output end is connected to the outside, causing the air pressure to return to normal. The leakage is relatively serious. The control center (1) activates the second measure, that is, the pump (24) reverses and pumps the water back into the cooling tank (221). At the same time, the liquid collection tank (25) collects the leakage. The control center (1) sends an electrical signal to the buzzer to provide a warning. When the detection device detects that the air pressure at the output end of the pump (24) drops and returns to normal air pressure in a short time, the load body (23) cannot continue to perform load testing on the server.

2. The testing method for a modular liquid-cooled load test chamber according to claim 1, characterized in that: S300, the real-time air pressure change data, water flow change data, and liquid level change data detected by the detection device can be classified by time into data within time period T1 (S1), data within time period T2 (S2), and data within time period T3 (S3). The control center (1) constructs a time-series prediction engineering model based on the data within time period T1 (S1), the data within time period T2 (S2), and the data within time period T3 (S3). In S200, when the air pressure change data, water flow change data, and liquid level change data are all less than the threshold, that is, when the air pressure change data, water flow change data, and liquid level change data at the output end of the pump (24) are all less than the threshold, the pump (24) output end is at a certain time. When the decrease in pressure and water flow is caused by the thermal expansion and contraction of water, 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, that is, the pump (24) will leak in the future. At this time, the control center (1) selects to activate 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, that is, the pump (24) will not leak in the future, the load body (23) can continuously perform load testing on the server.
