In order to prevent the leakage of cooling liquid, a sealing ring is usually installed between the water tap joint and the liquid cooling plate. However, during the actual installation process, there may be errors in the installation angle and position of the water tap joint, resulting in the inclined installation of the joint. This inclined installation will cause the sealing ring to be unevenly extruded, and thus lead to the cracking of the sealing ring. The failure of the sealing ring not only causes the leakage of cooling liquid, but also may cause the thermal runaway of the battery system, seriously affecting the safety and service life of the battery.
