In order to ensure that the battery pack or the power station can work stably in an environment with suitable temperature, a special thermal management system is required to ensure the temperature. Strict requirements are placed on the sealing of the pipeline, which poses new challenges to the manufacturing process of the pipeline assembly. Therefore, airtightness testing is introduced. However, it is difficult to achieve 100% testing of the pipeline product assembly during the airtightness test, and the pipeline product involves bellows that are easy to expand and contract when inflated, affecting the test results. This makes underwater airtightness testing an inevitable choice.

This equipment needs to use compressed air to test the air tightness of pipeline products and can directly and efficiently blow the pipeline products dry after the test is completed to avoid the test water adhering to the pipeline or dripping onto the ground. Therefore, an underwater air tightness detection device with high testing efficiency is urgently needed. Utility Model Content

[0017] (4) The product traceability function is realized through the camera, and the underwater lighting improves the real-time observation effect and the clarity of subsequent traceability;

Under the premise of ensuring the test effect, the degree of automation is improved, energy is saved, and efficiency is improved. BRIEF DESCRIPTION OF THE DRAWINGS
