The battery cold plate is an important component of the battery thermal management system. The thermal management performance of new energy batteries plays a crucial role in the performance and safety of batteries. Through static load tests on the cold plate, a matching test fixture is designed to study the strength of the cold plate, analyze the deformation of the cold plate, compare the strength differences between the formed cold plate and raw materials, and test the overall air tightness changes of the cold plate before and after the test. At the same time, based on the layout of the cooling space on the large surface of the battery and the actual expansion force load conditions of the battery, fatigue durability research on the cold plate is carried out. The deformation of the cold plate after the alternating load test is analyzed, and the overall air tightness changes of the cold plate before and after the test are tested. Through the results of the static load test and fatigue durability test of the cold plate, data guidance is provided for optimizing the structural design and spatial layout of the cold plate.
