Description

Technical Field

[0001] This application relates to the field of liquid-cooled testing equipment technology, and in particular to a multifunctional testing device. Background Technology

[0002] With the rapid development of computer technology, the heat generated by servers and data centers has increased dramatically, making traditional air cooling systems insufficient to meet the demand. Liquid cooling systems, by directly introducing coolant into the server's interior, can significantly improve the efficiency of heat absorption and removal, ensuring stable equipment operation. Consequently, the market demand for liquid cooling systems is growing daily.

[0003] In the manufacturing process of liquid cooling systems, it is often necessary to detect gas and liquid leaks in the liquid cooling pipelines. After the gas and liquid leak detection is completed, the liquid cooling pipelines will undergo multiple processes such as cleaning, sterilization, drying, and liquid injection according to different customer needs.

[0004] However, in the aforementioned production process, technicians at each stage need to use corresponding testing equipment, such as using an airtightness detector for leak detection and a pipeline cleaning machine for cleaning. Furthermore, during different process operations, the products to be tested need to be manually transferred between multiple testing devices, resulting in high labor intensity, low testing efficiency, and an inability to meet the requirements of high-efficiency production. Utility Model Content

[0005] In view of this, it is necessary to provide a multifunctional testing device to improve the technical problems of existing liquid cooling system testing devices having single functions and low testing efficiency.

[0006] One embodiment of this application provides a multifunctional testing device. The multifunctional testing device is configured to test an object, which has a liquid-cooled pipe. The multifunctional testing device includes a testing component, a gas pipeline, a first liquid pipeline, a second liquid pipeline, and a control component. The testing component is configured to be installed on the object and extend into the liquid-cooled pipe. The gas pipeline is configured to connect the liquid-cooled pipe of the object to an external gas source, allowing compressed gas to flow into the liquid-cooled pipe along the gas pipeline. The testing component is configured to monitor pressure changes within the liquid-cooled pipe. The first liquid pipeline is configured to connect the liquid-cooled pipe of the object to a coolant storage device, allowing coolant from the coolant storage device to be injected into the liquid-cooled pipe along the first liquid pipeline. The testing component is configured to monitor the flow rate of the coolant in the liquid-cooled pipe. The second liquid pipeline is configured to connect the liquid-cooled pipe of the object to a cleaning fluid storage device, allowing cleaning fluid from the cleaning fluid storage device to flow into the liquid-cooled pipe along the second liquid pipeline and clean the liquid-cooled pipe. The control component is connected to the gas line, the first liquid line, and the second liquid line respectively. The control component is configured to selectively control one of the gas line, the first liquid line, and the second liquid line to connect to the liquid cooling pipe of the test object.

[0007] In the aforementioned multifunctional testing equipment, by selectively controlling one of the gas pipeline, the first liquid pipeline, and the second liquid pipeline to connect with the liquid-cooled pipeline of the test object through the control component, the leakage detection, filling, draining, and cleaning processes of the liquid-cooled pipeline in the test object can be realized. Compared with traditional single-process testing using multiple devices, the multifunctional testing equipment provided in this application can integrate leakage detection, filling, draining, and cleaning processes into one device. Technicians do not need to transfer the test object between multiple devices, which helps to reduce the number of devices used, reduce the labor intensity of technicians, and improve production efficiency.

[0008] In some embodiments of this application, the multifunctional detection device further includes a gas heating assembly installed in a gas pipeline and connected to a control assembly. The gas heating assembly is configured to heat compressed gas flowing through the gas pipeline, thereby drying the liquid-cooled pipeline with the heated compressed gas.

[0009] After cleaning the liquid-cooled pipelines, the gas heating component heats the compressed gas flowing through them, effectively drying the pipelines. This reduces the risk of damage to the test items during long-term transportation due to the pipelines not being dry. Adding a gas heating component enhances the versatility of the multi-functional testing equipment, effectively adding a drying process and further improving production efficiency.

[0010] In some embodiments of this application, the multifunctional detection device further includes a first humidity detector and a second humidity detector. The first humidity detector is configured to be installed at the inlet of the liquid cooling pipe to monitor the humidity value at the inlet of the liquid cooling pipe. The second humidity detector is configured to be installed at the outlet of the liquid cooling pipe to monitor the humidity value at the outlet of the liquid cooling pipe.

[0011] If the readings of the first and second humidity sensors are the same (i.e., the humidity value at the inlet of the liquid cooling pipe is the same as the humidity value at the outlet of the liquid cooling pipe), it indicates that the liquid cooling pipe is completely dry; otherwise, it indicates that the liquid cooling pipe is not completely dry and further drying is required. The use of the first and second humidity sensors helps to ensure the complete drying of the liquid cooling pipe.

[0012] In some embodiments of this application, the first liquid pipeline includes a first inlet branch and a first outlet branch. The first inlet branch is configured to connect the inlet of the liquid-cooled pipeline and the coolant storage device, so that coolant in the coolant storage device can be injected into the liquid-cooled pipeline along the first inlet branch. The first outlet branch is configured to connect the outlet of the liquid-cooled pipeline and the gas branch, so that coolant in the liquid-cooled pipeline can be discharged along the first outlet branch when compressed gas flows into the liquid-cooled pipeline along the gas branch.

[0013] By setting up a first inlet branch and a first outlet branch, technicians can install both branches simultaneously, improving the efficiency of the first liquid pipeline installation. Furthermore, if either the first inlet or outlet branch becomes damaged or ages, technicians only need to replace the corresponding branch (specifically, the first inlet or outlet branch), without needing to replace the entire first liquid pipeline, thus reducing subsequent maintenance costs for the multi-functional testing equipment.

[0014] In some embodiments of this application, the second liquid pipeline includes a second inlet branch and a second outlet branch. The second inlet branch is configured to connect the inlet of the liquid-cooled pipeline and the cleaning fluid storage device. The second outlet branch is configured to connect the outlet of the liquid-cooled pipeline, so that the cleaning fluid in the cleaning fluid storage device can flow into the liquid-cooled pipeline along the second inlet branch and flow out along the second outlet branch.

[0015] By setting up a second inlet branch and a second outlet branch, technicians can install both branches simultaneously, improving the efficiency of the second liquid pipeline installation. Furthermore, if either the second inlet or outlet branch becomes damaged or ages, technicians only need to replace the corresponding branch (either the second inlet or outlet branch), without needing to replace the entire second liquid pipeline, further reducing the subsequent maintenance costs of the multi-functional testing equipment.

[0016] In some embodiments of this application, the first liquid inlet branch and the second liquid inlet branch are configured as the same pipeline.

[0017] By configuring the first liquid inlet branch and the second liquid inlet branch as the same pipeline (that is, the same pipeline can serve as both the first and second liquid inlet branches), the coolant in the coolant storage device and the cleaning fluid in the cleaning fluid storage device can flow into the liquid cooling pipeline along the same pipeline, which helps to reduce the internal pipelines in the multifunctional testing equipment and thus simplifies the internal structure of the multifunctional testing equipment.

[0018] In some embodiments of this application, the first liquid pipeline further includes a first liquid storage chamber and a second liquid storage chamber. The first liquid storage chamber is located in the first inlet branch and is configured to contain coolant during the process of coolant being injected into the liquid-cooled pipeline along the first inlet branch. The second liquid storage chamber is located in the first outlet branch and is configured to contain coolant during the process of coolant being discharged along the first outlet branch.

[0019] When filling the liquid-cooled pipes, the coolant can first be contained in the first reservoir before being injected into the pipes. When draining the liquid-cooled pipes, the coolant can first be contained in the second reservoir before being drained. The presence of the first and second reservoirs serves two purposes: firstly, it helps ensure the airtightness of the liquid-cooled pipes during the filling or draining processes, reducing the risk of external gases or contaminants (such as dust particles) entering the pipes; secondly, the first and second reservoirs can hold excess coolant, reducing the risk of leakage due to excessive coolant.

[0020] In some embodiments of this application, the second liquid pipeline further includes a third liquid storage chamber, which is located in the second liquid outlet branch and is configured to contain the cleaning liquid as it flows out along the second liquid outlet branch.

[0021] When cleaning the liquid-cooled pipes, the cleaning fluid can be contained in the third storage chamber. This serves two purposes: firstly, it helps ensure the airtightness of the liquid-cooled pipes during the cleaning process, and secondly, the third storage chamber can hold excess cleaning fluid.

[0022] In some embodiments of this application, the multifunctional testing device further includes a first drain pipe, a second drain pipe, and a third drain pipe. The first drain pipe is connected to a first liquid storage chamber, the second drain pipe is connected to a second liquid storage chamber, and the third drain pipe is connected to a third liquid storage chamber. The first drain pipe is configured to discharge coolant from the first liquid storage chamber to the outside, the second drain pipe is configured to discharge coolant from the second liquid storage chamber to the outside, and the third drain pipe is configured to discharge cleaning fluid from the third liquid storage chamber to the outside.

[0023] The installation of the first, second, and third drain pipes allows the residual liquid (specifically coolant and cleaning fluid) in the first, second, and third storage chambers to be discharged to the outside, which is beneficial for the maintenance and inspection of the multi-functional testing equipment.

[0024] In some embodiments of this application, the gas pipeline includes a first gas branch and a second gas branch, both of which are connected to a control component. A gas heating component is disposed in the first gas branch. The first gas branch is configured to be connected to an external air compressor, the second gas branch is configured to be connected to a gas storage device, and the control component is configured to selectively control one of the first and second gas branches to be connected to the liquid-cooled pipeline of the object to be tested.

[0025] By configuring the first and second gas branches, technicians can choose to introduce either compressed air or an inert gas (nitrogen) according to customer needs. For example, if compressed air might react chemically with the liquid in the liquid pipeline, the user can choose to introduce an inert gas (nitrogen). Furthermore, if either the first or second gas branch fails, the other can still function normally, eliminating the need for downtime for the multi-functional testing equipment and further improving production efficiency.

[0034] The following detailed description, in conjunction with the accompanying drawings, will further illustrate this application. Detailed Implementation

[0035] The technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0036] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0037] This application provides a multifunctional testing device. The multifunctional testing device is configured to test an object, which has a liquid-cooled pipe. The multifunctional testing device includes a testing component, a gas pipeline, a first liquid pipeline, a second liquid pipeline, and a control component. The testing component is configured to be installed on the object and extend into the liquid-cooled pipe. The gas pipeline is configured to connect the liquid-cooled pipe of the object to an external gas source, allowing compressed gas to flow into the liquid-cooled pipe along the gas pipeline. The testing component is configured to monitor pressure changes within the liquid-cooled pipe. The first liquid pipeline is configured to connect the liquid-cooled pipe of the object to a coolant storage device, allowing coolant from the coolant storage device to be injected into the liquid-cooled pipe along the first liquid pipeline. The testing component is configured to monitor the flow rate of the coolant in the liquid-cooled pipe. The second liquid pipeline is configured to connect the liquid-cooled pipe of the object to a cleaning fluid storage device, allowing cleaning fluid from the cleaning fluid storage device to flow into the liquid-cooled pipe along the second liquid pipeline and clean the liquid-cooled pipe. The control component is connected to the gas line, the first liquid line, and the second liquid line respectively. The control component is configured to selectively control one of the gas line, the first liquid line, and the second liquid line to connect to the liquid cooling pipe of the test object.

[0038] In the aforementioned multifunctional testing equipment, by selectively controlling one of the gas pipeline, the first liquid pipeline, and the second liquid pipeline to connect with the liquid-cooled pipeline of the test object through the control component, the leakage detection, filling, draining, and cleaning processes of the liquid-cooled pipeline in the test object can be realized. Compared with traditional single-process testing using multiple devices, the multifunctional testing equipment provided in this application can integrate leakage detection, filling, draining, and cleaning processes into one device. Technicians do not need to transfer the test object between multiple devices, which helps to reduce the number of devices used, reduce the labor intensity of technicians, and improve production efficiency.

[0039] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0040] Please see Figure 1 As shown, one embodiment of this application provides a multifunctional detection device 100. The multifunctional detection device 100 is configured to detect a test object 200, such as a sensor box. The test object 200 is provided with a liquid cooling pipe (not shown), which is configured to be filled with coolant. The coolant can absorb the heat of the test object 200, thereby cooling the test object 200.

[0041] In some embodiments, the multifunctional detection device 100 includes a detection component (not shown), a first liquid line 10, a second liquid line 20, a gas line 30, and a control component (not shown). The detection component is configured to be installed on the test object 200 and extend into the liquid-cooled pipeline to monitor various parameters within the liquid-cooled pipeline, such as pressure, flow rate, or temperature.

[0042] In some embodiments, the detection component may include a single sensor. A single sensor may detect multiple parameters such as pressure, flow rate, or temperature.

[0043] In some embodiments, the detection component may further include multiple sensors, each capable of detecting a corresponding parameter, such as pressure, flow rate, or temperature. This application does not limit this, and those skilled in the art can choose according to the actual situation.

[0044] In some embodiments, the control component is connected to the first liquid line 10, the second liquid line 20, and the gas line 30, respectively, and the control component is configured to selectively control one of the first liquid line 10, the second liquid line 20, and the gas line 30 to communicate with the liquid cooling pipe of the test object 200.

[0045] Please refer to the following: Figure 1 and Figure 2As shown, in some embodiments, the first liquid line 10 is configured to connect the liquid cooling pipe of the test object 200 and the coolant storage device 300, so that the coolant in the coolant storage device 300 can be injected into the liquid cooling pipe along the first liquid line 10, and the detection component is configured to monitor the flow rate of the coolant in the liquid cooling pipe.

[0046] Understandably, when the test object 200 is filled with liquid, the control component adjusts the connection between the first liquid line 10 and the liquid cooling pipe. The coolant storage device 300 injects coolant into the liquid cooling pipe along the first liquid line 10. At the same time, the flow rate of coolant in the liquid cooling pipe is monitored by the detection component to determine whether the liquid cooling pipe is full.

[0047] In some embodiments, the multifunctional detection device 100 can combine two parameters—the detection component monitoring the pressure change in the liquid cooling pipe and the detection component monitoring the flow rate of the coolant in the liquid cooling pipe—to determine whether the liquid cooling pipe is full, which helps to ensure the accuracy of the result of whether the liquid cooling pipe is full.

[0048] For example, the detection component monitors the total amount of coolant injected into the liquid cooling pipe while simultaneously monitoring pressure changes within the pipe. When the pressure in the liquid cooling pipe reaches its maximum value, and the measured total liquid volume matches the pipe's capacity, it indicates that the pipe is full of coolant; conversely, it indicates that the pipe is not full of coolant.

[0049] In other embodiments, the fullness of the liquid cooling pipeline can be determined solely by flow monitoring results or pressure monitoring results, or other determination methods can be used. This application does not limit this method, and those skilled in the art can choose according to the actual situation.

[0050] Please refer to the following: Figure 1 and Figure 3 As shown, in some embodiments, the second liquid line 20 is configured to connect the liquid cooling pipe of the test object 200 and the cleaning fluid storage device 400, so that the cleaning fluid in the cleaning fluid storage device 400 can flow along the second liquid line 20 into the liquid cooling pipe and clean the liquid cooling pipe.

[0051] Understandably, when the test object 200 is being cleaned, the control component adjusts the second liquid line 20 to connect with the liquid cooling pipe, and the cleaning liquid in the cleaning liquid storage device 400 flows into the liquid cooling pipe along the second liquid line 20 and cleans the liquid cooling pipe.

[0052] It is worth noting that technicians can flush the liquid-cooled pipeline of the test object 200 according to the set time and flow rate, which can be either circulating cleaning or flowing cleaning. This application does not limit this, and those skilled in the art can choose according to the actual situation.

[0053] Please refer to the following: Figure 1 and Figure 4 As shown, in some embodiments, the gas line 30 is configured to connect the liquid-cooled pipe of the test object 200 to an external gas source (which may be an air compressor 500, an inert gas storage device, etc.) so that compressed gas can flow into the liquid-cooled pipe along the gas line 30. The detection component is configured to monitor pressure changes within the liquid-cooled pipe.

[0054] Understandably, when performing leak detection on the test object 200, the control component adjusts the gas line 30 to connect with the liquid-cooled pipeline of the test object 200. An external gas source delivers compressed air or N2 (nitrogen) along the gas line 30 to the liquid-cooled pipeline, forming a closed test loop.

[0055] The detection component monitors the pressure changes within the liquid cooling pipe. If the pressure change curve within the liquid cooling pipe is almost horizontal, it indicates that there is no leakage in the liquid cooling pipe, which meets the requirements. If the pressure change curve within the liquid cooling pipe is decreasing, it indicates that there is a leak in the liquid cooling pipe, which does not meet the requirements.

[0056] For example, an external air source delivers compressed air along gas pipeline 30 into the liquid cooling pipeline. When the air pressure inside the cooling pipeline reaches 1.5 kPa, the external air source stops delivering compressed air. Subsequently, the detection component records the pressure changes in real time. If the pressure curve is almost horizontal (e.g., fluctuation < 0.5 kPa / min), it indicates that the liquid cooling pipeline has no leaks and meets the requirements; if the pressure curve drops (e.g., drops by 1 kPa per minute), it indicates that the liquid cooling pipeline has leaks and does not meet the requirements.

[0057] In other embodiments, other leak detection methods may also be used, such as tracer gas (e.g., helium), mass spectrometry to detect leaks, etc. This application does not limit the methods, and those skilled in the art can choose according to the actual situation.

[0058] Please refer to the following: Figure 1 and Figure 5 As shown, in some embodiments, when the test object 200 is drained, the control component adjusts the gas pipeline 30 to connect with the liquid-cooled pipeline of the test object 200. An external gas source delivers compressed air or N2 (nitrogen) along the gas pipeline 30 into the liquid-cooled pipeline. At this time, the liquid-cooled pipeline does not form a closed loop, and the coolant inside the liquid-cooled pipeline can be discharged under the action of the compressed gas.

[0059] The multifunctional testing equipment 100 provided in this application can selectively control one of the first liquid pipeline 10, the second liquid pipeline 20 and the gas pipeline 30 to connect with the liquid cooling pipeline of the test object 200 through the control component, so as to realize the leakage detection process, liquid filling process, liquid draining process and cleaning process of the liquid cooling pipeline in the test object 200.

[0060] Compared to traditional single-process testing using multiple devices, the multi-functional testing device 100 provided in this application can integrate leak detection, liquid filling process, liquid draining process, and cleaning process into one device. Technicians do not need to transfer the test object 200 between multiple devices, which helps to reduce the number of devices used, reduce the labor intensity of technicians, and improve production efficiency.

[0061] It should also be noted that by using the multi-functional testing device 100, technicians do not need to frequently plug and unplug interfaces, which helps to reduce the leakage of harmful gases and liquids (specifically coolant, cleaning fluid, or nitrogen) when plugging and unplugging interfaces, thus reducing environmental harm.

[0062] Please refer to the following: Figure 1 and Figure 6 As shown, in some embodiments, the multifunctional detection device 100 further includes a gas heating assembly 40, which is installed in the gas pipeline 30 and connected to the control assembly. The gas heating assembly 40 is configured to heat the compressed gas flowing through the gas pipeline 30, thereby drying the liquid-cooled pipeline with the heated compressed gas.

[0063] Understandably, when drying the liquid-cooled pipeline, the control component adjusts the gas pipeline 30 to connect with the liquid-cooled pipeline of the test object 200, and an external gas source delivers compressed air or N2 (nitrogen) along the gas pipeline 30 into the liquid-cooled pipeline. The gas heating component 40 operates, heating the compressed gas flowing through the gas pipeline 30, and the heated compressed gas can dry the liquid-cooled pipeline.

[0064] By adding a gas heating component 40, the versatility of the multifunctional testing equipment 100 can be further improved, namely by adding a drying process, thereby further improving production efficiency. In addition, the gas heating component 40 helps to reduce the risk of damage to the test object 200 due to the liquid cooling pipes not drying during long-term transportation.

[0065] In some embodiments, the gas heating component 40 can be a heating wire or a heating tube, which converts electrical energy into heat energy to heat the flowing compressed gas. In other embodiments, the gas heating component 40 can also be other components, which are not limited in this application, and those skilled in the art can choose according to the actual situation.

[0066] In some embodiments, the multifunctional detection device 100 further includes a first humidity sensor (not shown) and a second humidity sensor (not shown). The first humidity sensor is configured to be installed at the inlet of the liquid-cooled pipe to monitor the humidity value at the inlet of the liquid-cooled pipe. The second humidity sensor is configured to be installed at the outlet of the liquid-cooled pipe to monitor the humidity value at the outlet of the liquid-cooled pipe. The arrangement of the first and second humidity sensors helps to ensure the complete dryness of the liquid-cooled pipe.

[0067] In some embodiments, both the first and second humidity sensors are dew point sensors. For example, during the drying of a liquid-cooled pipe, the first dew point sensor monitors the humidity value at the inlet of the liquid-cooled pipe to generate a first humidity value. The second dew point sensor monitors the humidity value at the outlet of the liquid-cooled pipe to generate a second humidity value. If the first humidity value and the second humidity value are the same, it indicates that the liquid-cooled pipe is completely dry; if the first humidity value and the second humidity value are different, it indicates that the liquid-cooled pipe is not completely dry and further drying is required.

[0068] In other embodiments, the first humidity detection element and the second humidity detection element may also be other structures, and the multifunctional detection device 100 may also adopt other methods to determine the degree of drying of the liquid-cooled pipeline. This application does not limit this, and those skilled in the art can choose according to the actual situation.

[0069] Please refer to the following: Figure 1 , Figure 2 and Figure 5 As shown, in some embodiments, the first liquid pipeline 10 includes a first inlet branch 11 and a first outlet branch 12. The first inlet branch 11 is configured to connect the inlet of the liquid cooling pipeline and the coolant storage device 300, so that the coolant in the coolant storage device 300 can be injected into the liquid cooling pipeline along the first inlet branch 11.

[0070] The first liquid outlet branch 12 is configured to connect the outlet of the liquid cooling pipe and the gas pipe 30, so that the coolant in the liquid cooling pipe can be discharged along the first liquid outlet branch 12 when the compressed gas flows into the liquid cooling pipe along the gas pipe 30.

[0071] Understandably, when the test object 200 is filled with liquid, the control component adjusts the connection between the first inlet branch 11 and the liquid cooling pipe. The coolant storage device 300 injects coolant into the liquid cooling pipe along the first inlet branch 11. When the test object 200 is drained, the control component adjusts the connection between the first outlet branch 12 and the liquid cooling pipe, and simultaneously adjusts the connection between the gas pipe 30 and the liquid cooling pipe. An external gas source delivers compressed air or N2 (nitrogen) along the gas pipe 30 into the liquid cooling pipe, and the coolant in the liquid cooling pipe is discharged along the first outlet branch 12 under the action of the compressed gas.

[0072] By setting up a first inlet branch 11 and a first outlet branch 12, technicians can install both branches simultaneously, improving the efficiency of installing the first liquid pipeline 10. Secondly, if either the first inlet branch 11 or the first outlet branch 12 becomes damaged or ages, technicians only need to replace the corresponding branch (specifically, the first inlet branch 11 or the first outlet branch 12), without needing to replace the entire first liquid pipeline 10, thus reducing the subsequent maintenance costs of the multi-functional testing equipment 100.

[0073] Please refer to the following: Figure 1 and Figure 3 As shown, in some embodiments, the second liquid line 20 includes a second liquid inlet branch 21 and a second liquid outlet branch 22, wherein the second liquid inlet branch 21 is configured to connect the inlet of the liquid cooling pipe to the cleaning fluid storage device 400.

[0074] The second liquid outlet branch 22 is configured to connect to the outlet of the liquid cooling pipe so that the cleaning fluid in the cleaning fluid storage device 400 can flow into the liquid cooling pipe along the second liquid inlet branch 21 and flow out along the second liquid outlet branch 22.

[0075] Understandably, when the test object 200 is being cleaned, the control component adjusts the second liquid inlet branch 21 to connect with the inlet of the liquid cooling pipe, and the second liquid outlet branch 22 to connect with the outlet of the liquid cooling pipe. The cleaning fluid in the cleaning fluid storage device 400 flows into the liquid cooling pipe along the second liquid inlet branch 21 and flows out along the second liquid outlet branch 22 to achieve the cleaning of the liquid cooling pipe.

[0076] By setting up a second inlet branch 21 and a second outlet branch 22, technicians can install both simultaneously, improving the efficiency of installing the second liquid pipeline 20. Furthermore, if either the second inlet branch 21 or the second outlet branch 22 becomes damaged or ages, technicians only need to replace the corresponding branch (specifically, the second inlet branch 21 or the second outlet branch 22), without needing to replace the entire second liquid pipeline 20, further reducing the subsequent maintenance costs of the multi-functional testing equipment 100.

[0077] In some embodiments, the first liquid inlet branch 11 and the second liquid inlet branch 21 are configured as the same pipeline. In other words, the same pipeline can serve as both the first liquid inlet branch 11 and the second liquid inlet branch 21. The coolant in the coolant storage device 300 and the cleaning fluid in the cleaning fluid storage device 400 can flow into the liquid cooling pipeline along the same pipeline.

[0078] By configuring the first liquid inlet branch 11 and the second liquid inlet branch 21 as the same pipeline, it is beneficial to reduce the internal pipelines in the multifunctional testing device 100, thereby simplifying the internal structure of the multifunctional testing device 100.

[0079] Please refer to the following: Figure 2 , Figure 3 and Figure 5 As shown, in some embodiments, the first liquid pipeline 10 further includes a first liquid storage chamber 13 and a second liquid storage chamber 14. The first liquid storage chamber 13 is located in the first liquid inlet branch 11 and is configured to contain coolant during the process of coolant being injected into the liquid cooling pipeline along the first liquid inlet branch 11. The second liquid storage chamber 14 is located in the first liquid outlet branch 12 and is configured to contain coolant during the process of coolant being discharged along the first liquid outlet branch 12.

[0080] Understandably, when filling the liquid-cooled pipes, the coolant can first be contained in the first reservoir 13 before being injected into the liquid-cooled pipes. When draining the liquid-cooled pipes, the coolant can first be contained in the second reservoir 14 before being drained. The arrangement of the first reservoir 13 and the second reservoir 14 serves two purposes: firstly, it helps to ensure the airtightness of the liquid-cooled pipes during the filling or draining process, reducing the risk of external gases or contaminants (such as dust particles) entering the liquid-cooled pipes; secondly, the first reservoir 13 and the second reservoir 14 can hold excess coolant, reducing the risk of leakage in the liquid-cooled pipes due to excessive coolant.

[0081] In some embodiments, the second liquid line 20 further includes a third liquid storage chamber 23, which is located in the second liquid outlet branch 22. The third liquid storage chamber 23 is configured to contain cleaning fluid as it flows out along the second liquid outlet branch 22. When cleaning the liquid-cooled pipeline, the cleaning fluid can be contained in the third liquid storage chamber 23, which not only helps ensure the airtightness of the liquid-cooled pipeline during the cleaning process but also allows for the containment of excess cleaning fluid.

[0082] Please see Figure 1 As shown, in some embodiments, the multifunctional detection device 100 further includes a first drain pipe 50, a second drain pipe 60, and a third drain pipe 70. The first drain pipe 50 is connected to the first liquid storage chamber 13, the second drain pipe 60 is connected to the second liquid storage chamber 14, and the third drain pipe 70 is connected to the third liquid storage chamber 23.

[0083] The first drain pipe 50 is configured to drain the coolant in the first reservoir 13 to the outside, the second drain pipe 60 is configured to drain the coolant in the second reservoir 14 to the outside, and the third drain pipe 70 is configured to drain the cleaning fluid in the third reservoir 23 to the outside.

[0084] The first drain pipe 50, the second drain pipe 60 and the third drain pipe 70 can discharge the residual liquid (specifically coolant and cleaning fluid) in the first liquid storage chamber 13, the second liquid storage chamber 14 and the third liquid storage chamber 23 to the outside, which is beneficial for the maintenance and inspection of the multi-functional testing equipment 100.

[0085] In some embodiments, the first drain line 50, the second drain line 60, and the third drain line 70 are all configured to be manually opened or closed by a user. Technicians can manually open the first drain line 50, the second drain line 60, and the third drain line 70 to drain the residual liquid in the first liquid storage chamber 13, the second liquid storage chamber 14, and the third liquid storage chamber 23.

[0086] In other embodiments, the first drain line 50, the second drain line 60, and the third drain line 70 can also be automatically opened or closed by a control component, which helps to improve the intelligence level of the multifunctional testing device 100. This application does not limit this, and those skilled in the art can choose according to the actual situation.

[0087] Please refer to the following: Figure 1 , Figures 4 to 6 As shown, in some embodiments, the gas pipeline 30 includes a first gas branch 31 and a second gas branch 32, both of which are connected to the control component, and the gas heating component 40 is disposed in the first gas branch 31.

[0088] The first gas branch 31 is configured to be connected to an external air compressor 500, the second gas branch 32 is configured to be connected to a gas storage device 600, and the control component is configured to selectively control one of the first gas branch 31 and the second gas branch 32 to be connected to the liquid cooling pipe of the test object 200.

[0089] It is worth noting that the gas storage device 600 can store nitrogen or other inert gases, or other suitable gases. This application does not limit this, and those skilled in the art can choose according to the actual situation.

[0090] With the first gas branch 31 and the second gas branch 32 in place, technicians can choose to introduce compressed air or an inert gas (nitrogen) according to customer needs. For example, if compressed air may react chemically with the liquid in the liquid pipeline, the user can choose to introduce an inert gas (nitrogen).

[0091] In addition, if either the first gas branch 31 or the second gas branch 32 is damaged, the other can still work normally, and the multi-functional testing equipment 100 does not need to be shut down, which is conducive to further improving production efficiency.

[0092] For example, the working process of the multifunctional testing device 100 provided in this application is as follows:

[0093] First, the multifunctional testing device 100 performs leak detection on the test object 200. The control component connects the gas pipeline 30 to the liquid-cooled pipeline of the test object 200. An external gas source delivers compressed air or N2 (nitrogen) along the gas pipeline 30 into the liquid-cooled pipeline, forming a closed test loop. The testing component monitors the pressure changes within the liquid-cooled pipeline. If the pressure change curve within the liquid-cooled pipeline is almost horizontal, it indicates that there is no leak in the liquid-cooled pipeline, meeting the requirements; if the pressure change curve within the liquid-cooled pipeline is decreasing, it indicates that there is a leak in the liquid-cooled pipeline, failing to meet the requirements.

[0094] After the leak detection is completed, the multi-functional detection device 100 fills the test object 200 with liquid, and the control component adjusts the connection between the first liquid pipeline 10 and the liquid cooling pipeline. The coolant storage device 300 injects coolant into the liquid cooling pipeline along the first liquid pipeline 10. At the same time, the detection component monitors the flow rate of coolant in the liquid cooling pipeline to determine whether the liquid cooling pipeline is full.

[0095] After the coolant in the liquid-cooled pipeline is filled, the multi-functional testing device 100 drains the coolant from the test object 200, and the control component connects the gas pipeline 30 to the liquid-cooled pipeline of the test object 200. An external gas source delivers compressed air or N2 (nitrogen) along the gas pipeline 30 into the liquid-cooled pipeline. At this time, the liquid-cooled pipeline does not form a closed loop, and the coolant in the liquid-cooled pipeline is discharged under the action of the compressed gas.

[0096] After the coolant in the liquid-cooled pipeline is drained, the multi-functional testing device 100 cleans the test object 200. The control component adjusts the connection between the second liquid pipeline 20 and the liquid-cooled pipeline. The cleaning fluid in the cleaning fluid storage device 400 flows into the liquid-cooled pipeline along the second liquid pipeline 20 and cleans the liquid-cooled pipeline. Technicians set the time and flow rate as needed.

[0097] After the liquid-cooled pipeline is cleaned, the multi-functional testing device 100 dries the test object 200. The control component connects the gas pipeline 30 to the liquid-cooled pipeline of the test object 200, and an external gas source delivers compressed air or N2 (nitrogen) along the gas pipeline 30 into the liquid-cooled pipeline. The control component controls the gas heating component 40 to operate, which heats the compressed gas flowing through the gas pipeline 30, and the heated compressed gas dries the liquid-cooled pipeline. After drying is complete, the test object 200 can be removed.

[0098] Furthermore, those skilled in the art should recognize that the above embodiments are merely illustrative of this application and are not intended to limit this application. Any appropriate changes and variations made to the above embodiments within the essential spirit and scope of this application fall within the scope of this application's disclosure.
