Abstract

The invention discloses a power battery pack thermal management system and a vehicle. The power battery pack thermal management system comprises a shell, a water pump and a heat dissipator, wherein abattery module, a semiconductor refrigeration sheet and a water-cooling plate pipeline are arranged in the shell, one end of the semiconductor refrigeration sheet is connected to the battery module, the other end of the semiconductor refrigeration sheet is connected to the water-cooling plate pipeline, the water-cooling plate pipeline is connected to the water pump through a water pipe, and the water pipe is connected to the heat dissipator through a pipeline. According to the present invention, the cooling effect of the water cooling method is substantially improved compared to the natural air cooling and the active air cooling, the water in the water-cooling plate pipeline is introduced out of the high temperature device body, the water pump drives the water circulation, and the hot water in the water pipe is cooled by the heat dissipator, such that the water temperature in the water-cooling plate pipeline can be rapidly cooled; and the cooling liquid pipeline is not arranged in thebattery pack, such that the safety and the reliability can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a thermal management system for a power battery pack and an automobile. Background technique [0002] With the development of new energy pure electric vehicles, power batteries have been widely used in new energy vehicles. Performances such as cruising range, fast charging technology, cycle life and safety have higher requirements for the thermal management system of power battery packs. The power cells of vehicles are all made of ternary materials with high energy density. As the energy density increases, the risk of thermal runaway also increases. A thermal management system is required to control the power battery to work at a suitable temperature. [0003] The thermal management and cooling technologies for power battery packs of new energy vehicles mainly include natural cooling, air cooling, liquid cooling, and semiconductor refrigeration. Refrigeration or heating syst...
