Description
Technical Field
[0001] This utility model relates to the field of water-cooled plate testing technology, and specifically discloses a water-cooled plate testing platform. Background Technology
[0002] As a core component of the thermal management system for new energy vehicle batteries, the water-cooled plate's function is to efficiently and promptly dissipate the heat generated during battery charging and discharging through the circulation of coolant in its internal channels. This ensures the battery operates within its optimal temperature range, which is crucial for guaranteeing battery life, safety, and overall vehicle performance. If the water-cooled plate leaks, the coolant will directly contact the battery module, potentially leading to serious safety incidents such as short circuits and fires. Therefore, rigorous and reliable sealing tests on the water-cooled plate before shipment are an indispensable and critical step in ensuring product quality.
[0003] Currently, the existing technology for testing the sealing performance of water-cooled plates typically employs an overall air pressure test method, such as the direct pressure method or the differential pressure method. This method involves filling the entire water-cooled plate with pressurized gas and monitoring its pressure drop or the pressure difference with a standard container to determine whether there is a leak. However, this method can only determine whether the water-cooled plate is leaking, but it cannot pinpoint the exact location of the leak. This is not conducive to tracing and improving the manufacturing process during production.
[0004] In addition, common testing methods usually involve placing the water-cooled plate directly on the support platform and pressing it down for sealing testing. However, because the bottom side of the water-cooled plate is in close contact with the upper surface of the support platform, even if a leak occurs in this area, it is difficult to be directly observed, leading to the risk of missed detection. For example, the structure of a water-cooled plate testing device for new energy vehicles disclosed in Chinese Patent No. CN120538759A has this problem.
[0005] Therefore, a water-cooled plate testing platform is needed to solve the above problems. Utility Model Content
[0006] This invention proposes a water-cooled plate testing platform that uses a combination of water injection and gas pressurization for detection. This method can intuitively display the specific location of leaks, which helps to quickly trace the source of leaks and improve manufacturing processes during production. At the same time, it effectively avoids blind spots caused by component obstruction, thereby improving the comprehensiveness and reliability of detection and significantly reducing the risk of missed detections.
[0007] This utility model is implemented as follows: a water-cooled plate testing platform includes a support platform and a water-cooled plate body. The left side of the water-cooled plate body has a water inlet and a water outlet. A sealing detection mechanism and a movable clamping mechanism are provided above the support platform.
[0008] The sealing testing mechanism includes a vertical plate fixedly connected to the upper part of a support platform. A water tank is fixedly connected to the right end of the vertical plate. An L-shaped positioning tube is connected to the lower end of the water tank. Two connecting columns are fixedly connected to the outer wall of the L-shaped positioning tube. A positioning sleeve is fixedly connected to the other end of the two connecting columns. A fixing ring is fixedly connected to the inside of the positioning sleeve and the inside of the L-shaped positioning tube. A sealing ring is embedded in the right end of each of the two fixing rings. An exhaust pipe with a solenoid valve is connected to the outer wall of the positioning sleeve. An observation tube is connected to the upper end of the exhaust pipe. An air pump is installed at the right end of the vertical plate. A pressure-holding pipe with a solenoid valve is connected between the air outlet of the air pump and the water tank.
[0009] The movable clamping mechanism includes a mounting frame fixedly connected to the upper end of the support platform. A first servo electric actuator is installed inside the mounting frame. A lifting plate is fixedly connected to the output end of the first servo electric actuator. A second servo electric actuator is installed at the right end of the lifting plate. A pressure sensor is installed at the output end of the second servo electric actuator. A U-shaped frame is installed at the left end of the pressure sensor. A clamping wheel that abuts against the right end of the water-cooled plate body is rotatably connected inside the U-shaped frame.
[0010] As a preferred embodiment of the water-cooled plate testing platform of this utility model, an operation panel and a central controller are installed on the right end of the mounting frame.
[0011] As a preferred embodiment of the water-cooled plate testing platform of this utility model, the lower end of the lifting plate is fixedly connected to two first sliding rods that penetrate the mounting frame and are slidably connected to the mounting frame, and the right end of the U-shaped frame is fixedly connected to two second sliding rods that penetrate the lifting plate and are slidably connected to the lifting plate.
[0012] As a preferred embodiment of the water-cooled plate testing platform of this utility model, the upper end of the water injection tank is connected to an injection port equipped with a solenoid valve.
[0013] As a preferred embodiment of the water-cooled plate testing platform of this utility model, the observation tube is made of transparent material.
[0014] As a preferred embodiment of the water-cooled plate testing platform of this utility model, two first reinforcing plates are fixedly connected between the L-shaped positioning tube and the upright plate, and a second reinforcing plate is fixedly connected between the L-shaped positioning tube and the support platform.
[0015] As a preferred embodiment of the water-cooled plate testing platform of this utility model, the right edge of the inner wall of the positioning sleeve and the L-shaped positioning tube is chamfered.
[0016] The beneficial effects of this utility model are:
[0017] 1. After securing the water-cooled plate, fill the water tank with water. The water flows through the L-shaped positioning tube, entering the water-cooled plate through the inlet and finally exiting through the outlet. When the water fills the vent pipe and rises to the observation tube, the air in the pipe is completely expelled, and water filling is stopped. After closing the solenoid valves of the vent pipe and the inlet, a preliminary leak inspection can be performed. Then, start the air pump to send compressed air through the pressure-holding pipe to the top of the water tank, pressurizing the water column in the downstream pipe. Afterward, close the solenoid valve of the pressure-holding pipe. Operators can determine the sealing performance by observing whether water seeps onto the outer surface of the water-cooled plate. This detection method, combining water filling and gas pressurization, can visually display the specific location of the leak, helping to quickly trace the source of the leak during production and improve manufacturing processes.
[0018] 2. During the pressure testing process, the first servo electric actuator moves the lifting plate and the clamping roller downwards a certain distance, causing the clamping roller to disengage from its original position against the water-cooling plate. This operation fully exposes the obscured area to the field of vision, facilitating direct observation of any water seepage. This effectively avoids blind spots caused by component obstruction, improving the comprehensiveness and reliability of the test and significantly reducing the risk of missed detections.

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.
[0026] Please see Figure 1-4 A water-cooled plate testing platform includes a support platform 1 and a water-cooled plate body 2. The water-cooled plate body 2 has an inlet 3 and an outlet 4 on its left side. A sealing detection mechanism and a movable clamping mechanism are provided above the support platform 1.
[0027] The sealing test mechanism includes a vertical plate 13 fixedly connected to the upper end of the support platform 1. A water tank 5 is fixedly connected to the right end of the vertical plate 13. An L-shaped positioning tube 6 is connected to the lower end of the water tank 5. Two connecting columns are fixedly connected to the outer wall of the L-shaped positioning tube 6. A positioning sleeve 7 is fixedly connected to the other end of the two connecting columns. A fixing ring 8 is fixedly connected to the inside of the positioning sleeve 7 and the inside of the L-shaped positioning tube 6. A sealing ring 9 is embedded in the right end of each of the two fixing rings 8. An exhaust pipe 10 with a solenoid valve is connected to the outer wall of the positioning sleeve 7. An observation tube 11 is connected to the upper end of the exhaust pipe 10. An air pump 12 is installed at the right end of the vertical plate 13. A pressure holding pipe 14 with a solenoid valve is connected between the air outlet of the air pump 12 and the water tank 5.
[0028] The movable clamping mechanism includes a mounting frame 16 fixedly connected to the upper end of the support platform 1. A first servo electric actuator 17 is installed inside the mounting frame 16. A lifting plate 18 is fixedly connected to the output end of the first servo electric actuator 17. A second servo electric actuator 19 is installed at the right end of the lifting plate 18. A pressure sensor 21 is installed at the output end of the second servo electric actuator 19. A U-shaped frame 20 is installed at the left end of the pressure sensor 21. A clamping wheel 22 that abuts against the right end of the water-cooled plate body 2 is rotatably connected inside the U-shaped frame 20.
[0029] In this embodiment: First, the operator inserts the water inlet 3 of the water-cooled plate body 2 into the L-shaped positioning tube 6, and simultaneously inserts the water outlet 4 into the positioning sleeve 7, ensuring that the water inlet 3 and water outlet 4 are respectively in contact with the two sealing rings 9. Through the cooperation of the water inlet 3 and the L-shaped positioning tube 6, and the cooperation of the water outlet 4 with the positioning sleeve 7, the water-cooled plate body 2 is prevented from shifting in the up, down, front, and back directions, thus completing the initial positioning of the water-cooled plate body 2. Then, the second servo electric actuator 19 is activated to push the U-shaped frame 20 to the left, causing the pressure roller 22 inside the U-shaped frame 20 to abut against the right end of the water-cooled plate body 2. At this time, the pressure sensor 21 monitors the pressure received and transmits the signal to the central controller. The central controller then dynamically controls the movement of the second servo electric actuator 19, ensuring that the pressure roller 22 always maintains a suitable contact force with the water-cooled plate body 2, thereby ensuring that the water inlet 3 and water outlet 4 are tightly abutted against the two sealing rings 9, preventing fluid leakage during subsequent operations.
[0030] After securing the water-cooled plate body 2, water is injected into the water tank 5. The water flows through the L-shaped positioning pipe 6 into the inlet 3, then into the interior of the water-cooled plate body 2, and finally out through the outlet 4. When the water fills the vent pipe 10 and rises to the observation pipe 11, all the air inside the pipe is expelled, and water injection is stopped. The solenoid valves on the vent pipe 10 and the injection port 15 are closed. At this stage, the initial leakage can be directly observed. Then, the air pump 12 is turned on. The compressed air generated by the air pump 12 enters the top of the water tank 5 through the pressure holding pipe 14, pressurizing the water column in the downstream pipeline. After pressurization, the solenoid valve of the pressure holding pipe 14 is closed. The operator can directly observe whether there is water seepage on the outer surface of the water-cooled plate body 2 to determine the sealing performance. This detection method, which combines water injection and gas pressurization, can intuitively display the specific location of the leak, helping to quickly trace the source of the leak and improve the manufacturing process during production.
[0031] During the pressurization process, the first servo electric actuator 17 is activated, which drives the lifting plate 18 and the clamping wheel 22 to move downward a certain distance, so that the clamping wheel 22 avoids the original position of abutting the water-cooled plate body 2. Then observe whether there is water seepage, thereby effectively avoiding the blind spot caused by component obstruction, thus improving the comprehensiveness and reliability of the detection and significantly reducing the risk of missed detection.
[0032] As a technical optimization of this utility model, an operation panel and a central controller are installed on the right end of the mounting bracket 16.
[0033] In this embodiment: the operation panel installed on the right end of the mounting bracket 16 is used to input commands, and the central controller receives the commands from the operation panel and controls the operation of the first servo electric actuator 17, the second servo electric actuator 19, the air pump 12 and each solenoid valve; and the central controller is responsible for receiving the signal from the pressure sensor 21 and controlling the action of the second servo electric actuator 19.
[0034] As a technical optimization of this utility model, the lower end of the lifting plate 18 is fixedly connected to two first sliding rods that pass through the mounting bracket 16 and are slidably connected to the mounting bracket 16, and the right end of the U-shaped frame 20 is fixedly connected to two second sliding rods that pass through the lifting plate 18 and are slidably connected to the lifting plate 18.
[0035] In this embodiment: by setting a first sliding rod, the stability of the lifting plate 18 is improved; by setting two second sliding rods, the stability of the movement of the U-shaped frame 20 is improved.
[0036] As a technical optimization of this utility model, the upper end of the water tank 5 is connected to an injection port 15 with a solenoid valve.
[0037] In this embodiment: by providing an injection port 15, water can be added into the water tank 5.
[0038] As a technical optimization of this utility model, the observation tube 11 is made of transparent material.
[0039] In this embodiment: Since the observation tube 11 is made of transparent material, it is possible to clearly see whether water has entered the inside of the observation tube 11.
[0040] As a technical optimization of this utility model, two first reinforcing plates are fixedly connected between the L-shaped positioning tube 6 and the upright plate 13, and a second reinforcing plate is fixedly connected between the L-shaped positioning tube 6 and the support platform 1.
[0041] In this embodiment, by setting two first reinforcing plates and a second reinforcing plate, the stability of the L-shaped positioning tube 6 installation is improved.
[0042] As a technical optimization of this utility model, the right edge of the inner wall of both the positioning sleeve 7 and the L-shaped positioning tube 6 is chamfered.
[0043] In this embodiment: Since the right edge of the inner wall of both the positioning sleeve 7 and the L-shaped positioning tube 6 is chamfered, the beveled surface of the chamfer has a guiding function, which facilitates the insertion of the inlet 3 and the outlet 4.
[0044] The working principle and usage process of this utility model are as follows: First, the operator inserts the water inlet 3 of the water-cooled plate body 2 into the L-shaped positioning tube 6, and simultaneously inserts the water outlet 4 into the positioning sleeve 7, ensuring that the water inlet 3 and water outlet 4 are respectively in contact with the two sealing rings 9. Through the mutual cooperation of the water inlet 3 and the L-shaped positioning tube 6, and the mutual cooperation of the water outlet 4 and the positioning sleeve 7, the water-cooled plate body 2 is prevented from shifting in the up, down, front, and back directions, thus completing the initial positioning of the water-cooled plate body 2. Then, the second servo electric actuator 19 is activated to push the U-shaped frame 20 to the left, causing the pressure roller 22 inside the U-shaped frame 20 to abut against the right end of the water-cooled plate body 2. At this time, the pressure sensor 21 monitors the pressure received and transmits the signal to the central controller. The central controller then dynamically controls the action of the second servo electric actuator 19, ensuring that the pressure roller 22 always maintains a suitable contact force with the water-cooled plate body 2, thereby ensuring that the water inlet 3 and water outlet 4 are tightly abutted against the two sealing rings 9, preventing fluid leakage during subsequent operations.
[0045] After fixing the water-cooled plate body 2, water is injected into the water injection tank 5 through the injection port 15 at the top of the water injection tank 5. The water flows through the L-shaped positioning pipe 6 into the water inlet 3, and then into the interior of the water-cooled plate body 2 from the water inlet 3, before flowing out from the water outlet 4. When the water fills the vent pipe 10 and rises to the observation pipe 11, all the air inside the pipe is expelled, and water injection is stopped at this point. The solenoid valves on the vent pipe 10 and the injection port 15 are closed. At this stage, the initial water leakage can be directly observed. Then, the air pump 12 is turned on. The compressed air generated by the air pump 12 enters the top of the water injection tank 5 through the pressure holding pipe 14 to pressurize the water column in the downstream pipeline. After pressurization, the solenoid valve of the pressure holding pipe 14 is closed. The operator can directly observe whether there is water seepage on the outer surface of the water-cooled plate body 2 to judge the sealing performance. This detection method, which combines water injection and gas pressurization, can intuitively display the specific location of the leak, which helps to quickly trace the source of the leak and improve the manufacturing process during production.
[0046] During the pressurization process, the first servo electric actuator 17 is activated, which drives the lifting plate 18 and the clamping wheel 22 to move downward a certain distance, so that the clamping wheel 22 avoids the original position of abutting the water-cooled plate body 2. Then observe whether there is water seepage, thereby effectively avoiding the blind spot caused by component obstruction, thus improving the comprehensiveness and reliability of the detection and significantly reducing the risk of missed detection.
