Description

technical field [0001] The invention relates to the field of new energy, in particular to a cooling system for a battery of a new energy vehicle. Background technique [0002] An electric vehicle (BEV) refers to a vehicle that is powered by a vehicle-mounted power supply, drives the wheels with a motor, and meets the requirements of road traffic and safety regulations. Due to its smaller impact on the environment than traditional cars, its prospects are widely optimistic. As the power source of electric vehicles - battery, its current main cooling methods include: natural cooling, air cooling and liquid cooling. However, in the existing battery packaging structure, the battery cooling method has problems such as poor cooling effect and high cooling cost. Therefore, how to design a packaging structure and battery cooling system for electric vehicle battery packs with good heat dissipation performance is an urgent problem to be solved in the industry.
