[0002] New energy vehicles refer to vehicles that use unconventional automotive fuels as their power source. Electric vehicles are relatively mature new energy vehicles. Electric vehicles are driven by electricity. Therefore, battery packs, as electrical energy storage components, are one of the important components of electric vehicles.

[0003] Since the battery pack is generally installed on the chassis of the car, the battery pack of the electric vehicle maintains high power output for a long time during driving, which will generate more heat, so a water cooling plate is needed to cool it down. Therefore, the air tightness test of the water cooling plate of the new energy vehicle battery in the factory is necessary.

[0004] However, the air inlet interface of the battery water cooling plate is a straight tube with a smooth inner wall. In general, the friction force of the clamp seal is insufficient, and the tooling and the pipe will be separated under the reaction force of the test gas during the test, affecting the product test. Therefore, it is proposed that the device structure can achieve the quick connection, clamping and sealing of the smooth straight pipe interface by tightening the clamp inside. Utility Model Content
