Description

Technical Field

[0002] In recent years, with the rapid development of electric vehicles, more and more people use electric vehicles as a means of transportation. Therefore, the safety of electric vehicles has been paid more and more attention. As an important part of electric vehicles, the safety and reliability of the battery module are one of the important guarantees for electric vehicles. As a component for cooling equipment, the water cooling plate is an essential part of the battery module, and its airtightness seriously affects the safety and reliability of the battery module. Therefore, detecting its airtightness is an important process in the production of battery modules.

[0003] In the existing detection methods, some are to put the water cooling plate into water to judge its airtightness. In addition, there is also a method of directly connecting the water cooling plate to the connecting air pipe of the detection equipment for detection. However, whether it is the immersion in water detection or the direct connection of the air pipe method, before the test, workers need to connect the connection valve of the air pipe to the water inlet and outlet of the water cooling plate to carry out the test. However, due to the uncertain factors of the operator in this operation step, it is easy to cause the connection valve to be not connected in place, resulting in air leakage and invalidation of the detection result. Moreover, during the test, because a relatively large air pressure needs to be introduced into the water cooling plate, there is a certain danger. Therefore, the traditional detection method needs to be improved. In this regard, it is necessary to develop a device that is convenient for detecting the airtightness of the water cooling plate.
