[0002] During the operation of lithium battery modules, liquid cooling pipes play a crucial role in heat dissipation, ensuring the battery operates within a suitable temperature range, thereby improving battery performance, extending lifespan, and ensuring safety. Common lithium battery liquid cooling pipes are flat in shape. This flat shape allows for better contact with the battery module surface, increasing the contact area and making heat exchange between the coolant and the battery module more efficient. This contributes to uniform heat dissipation and improves the overall performance of the battery module. Simultaneously, the flat design better adapts to the compact internal space of the lithium battery module, improving space utilization and facilitating miniaturization and lightweight design.

[0003] In most current tests of the gas tightness of lithium battery liquid cooling pipes, it is difficult to clamp flat lithium battery liquid cooling pipes. During the test, shaking and displacement are very likely to occur, leading to inaccurate test results. Utility Model Content

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0027] In the description of the embodiments of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing the embodiments of this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this utility model.

[0028] In the description of the embodiments of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation", "connection" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, an integral connection, or a detachable connection; they can refer to the internal connection of two components; they can refer to a direct connection or an indirect connection through an intermediate medium. For those skilled in the art, the specific meaning of the above terms in the embodiments of this utility model can be understood according to the specific circumstances.

[0029] See appendix Figures 1-5 As shown, the liquid-cooled pipe airtightness testing equipment of this utility model includes a base 1, a water tank 101 on the upper surface of the base 1, an mounting plate 3 fixedly installed on one side of the water tank 101, a sliding groove 303 on one side of the mounting plate 3, a sliding block 304 slidably installed in the sliding groove 303, a linkage block 305 fixedly connected to the other end of the sliding block 304, a clamping test component 4 fixedly connected to one end of the linkage block 305, and a clamping test component 4 clamping a liquid-cooled pipe fitting 102 at one end of the clamping surface of the clamping test component 4.

[0030] The water tank 101 is made of glass, and the liquid cooling pipe fitting 102 has inlets and outlets on both sides for connecting to the inflation test equipment.

[0031] A support plate 2 is fixedly installed on one end of the lower surface of the inner wall of the water tank 101. When the liquid cooling pipe 102 enters the water tank 101 through the clamping test assembly 4, it can fit against one end of the upper surface of the support plate 2.

[0032] The sliding block 304 has a threaded hole at one end, and a lead screw 302 is threaded into the threaded hole. The other end of the upper surface of the base 1 is equipped with a drive motor 301, and the output shaft of the drive motor 301 is connected to one end of the lead screw 302.

[0033] When the liquid cooling pipe 102 enters the water tank 101 through the clamping test assembly 4, the bearing plate 2 of the above technical solution can prevent the bottom surface of the liquid cooling pipe 102 from being completely adhered, thereby effectively observing whether there is a problem of air leakage in the liquid cooling pipe 102, and facilitating the use of liquid cooling pipe air tightness testing equipment.

[0034] The design of the lead screw 302 and drive motor 301 facilitates the lifting and lowering of the liquid-cooled pipe 102 clamped in the clamping test assembly 4 from the water tank 101, which makes the placement and testing process of the liquid-cooled pipe 102 faster and more efficient, and completes the testing of multiple liquid-cooled pipes 102 in a short time, thereby improving the testing efficiency on the production line.

[0035] To further improve the stable clamping capability of the liquid cooling pipe 102 during the testing process, in this embodiment of the utility model, the clamping test component 4 can effectively clamp the liquid cooling pipe 102, ensuring that it will not be affected during the airtightness test. It can also be adapted to various specifications of liquid cooling pipe 102, improving its compatibility. It can achieve rapid clamping during clamping, improving its testing efficiency. Furthermore, the clamping test component 4 and the water tank 101 made of glass material can increase the observation area, ensuring accurate identification of the leakage location and improving the product quality of the liquid cooling pipe 102.

[0036] See appendix Figures 4 to 5 As shown, the clamping test assembly 4 includes a connecting plate 401, which is fixedly connected to one end of the lower surface of the linkage block 305. The connecting plate 401 is in the shape of a "7", and a first fixing block 402 is fixedly installed at one end of the connecting plate 401.

[0037] An electric push rod 403 is provided at one end of the lower surface of the first fixed block 402. The piston rod of the electric push rod 403 is connected to a pressure plate 404. The pressure plate 404 is U-shaped, and corrugated plates 405 are fixedly installed at both ends of the lower surface of the pressure plate 404.

[0038] A second fixing block 406 is fixedly connected to one end of the lower surface of the connecting plate 401. A connecting rod 407 is welded to one end of the lower surface of the second fixing block 406. A U-shaped plate 408 is fixedly connected to the other end of the connecting rod 407.

[0039] Angle blocks 409 are fixedly installed at both ends of the lower surface of the U-shaped plate 408. The liquid cooling pipe 102 drives the pressure plate 404 to rise and fall through the extension and retraction of the piston rod of the electric push rod 403, so that it is clamped between the pressure plate 404 and the U-shaped plate 408.

[0040] To improve stability during lithium battery liquid cooling pipe testing, the pressure stabilizing plate 404 is U-shaped, and the corrugated plates 405 fixedly installed at both ends of the lower surface can increase the contact area and friction with the liquid cooling pipe 102, preventing displacement of the liquid cooling pipe 102 during testing and improving stability during airtightness testing. Subsequently, the U-shaped plate 408 attached to the lower surface of the liquid cooling pipe 102 can effectively bear the load, and when entering the water tank 101, the angular blocks 409 installed at both ends of the lower surface of the U-shaped plate 408 can reduce the buoyancy effect of the water in the water tank 101 on the liquid cooling pipe 102, thereby preventing the liquid cooling pipe 102 from shaking or colliding due to water flow impact when entering the water tank 101.

[0041] This embodiment of the invention involves placing the liquid-cooled pipe fitting 102 to be tested upright on the U-shaped plate 408, connecting the inlet and outlet pipes on both sides of the liquid-cooled pipe fitting 102 to the test pipes, and using the piston rod of the electric push rod 403 to drive the pressure plate 404 to descend, causing the corrugated plate 405 on the lower surface of the pressure plate 404 to fit against the surface of the liquid-cooled pipe fitting 102. The drive motor 301 is then activated to start the lead screw 302, causing the lead screw 302 to drive the connecting plate 401 connected to one end of the sliding block 304 to descend, allowing the clamped liquid-cooled pipe fitting 102 to enter the water tank 101. During the entry process, the angular block 409 provided on the lower surface of the U-shaped plate 408 can reduce the influence of buoyancy, allowing the liquid cooling pipe 102 to contact the support plate 2 installed in the water tank 101, avoiding the bottom being blocked and affecting the view. After the airtightness test is completed, the drive motor 301 reverses and drives the lead screw 302 to rotate in the opposite direction, causing the sliding block 304 to drive the clamping assembly to rise, removing the liquid cooling pipe 102 from the water tank 101. The piston rod of the electric push rod 403 retracts and drives the pressure plate 404 to rise, releasing the clamping of the liquid cooling pipe for the next test operation.

[0042] In summary, the liquid cooling tube airtightness testing equipment of this utility model can effectively clamp the flat lithium battery liquid cooling tube, ensuring the stability of the liquid cooling tube throughout the testing process, preventing shaking or displacement, effectively guaranteeing the accuracy of the test results, and avoiding the risk of equipment or product damage caused by the liquid cooling tube slipping.
