With the development of society, automobiles are more and more popularized in ordinary families, so that the number of the automobiles is more and more, and because the traditional automobiles are generally driven by fuel engines, the emission of automobile exhaust is increased, and the air environment of our life is inevitably influenced. In order to meet the requirements of the future automobile exhaust emission, the electric automobile as a novel energy automobile hardly emits exhaust in the using process, and becomes one of the important choices of the future automobile. An electric vehicle generally refers to a vehicle that runs with a power battery pack as a power source and with wheels driven by a motor. The power battery pack is used as a new power source, and the technical indexes of the power battery pack require that the power battery pack has an ultra-long service life, safe use, large endurance and the like. Among them, the temperature has an important influence on the performance and the service life of the power battery pack. In order to ensure that the electric automobile can work safely and normally in various environments, the conventional power battery pack is generally required to be provided with a liquid cooling system with a water cooling plate to cool the power battery pack.

However, in order to improve the cruising ability of the power battery pack, it is desirable to place as many battery modules as possible in the space of the power battery pack. Therefore, the power battery pack utilizes the space in the vertical direction under the condition that the horizontal area is limited, and is connected with more battery modules in the vertical direction, so that the space utilization rate in the power battery pack is increased. Furthermore, the water inlet and outlet joint of the water cooling plate is arranged at the bottom of the water cooling plate and is downward. The water cooling plate water inlet and outlet connector protrudes downwards, and the water cooling plate water inlet and outlet connector can touch external substances to be damaged before installation, or foreign matters enter the water cooling plate water inlet and outlet connector. In addition, in the process of installing the water inlet and outlet joint of the water cooling plate, the water inlet and outlet joint of the water cooling plate may touch the lower shell of the battery pack to be damaged due to the space limitation of the lower shell of the battery pack.
