Compared with the traditional fuel oil vehicle, the new energy vehicle has remarkable advantages in the aspects of energy conservation, emission reduction and environmental pollution reduction, and particularly, the electric vehicle can realize zero emission driving by using a battery as a power source, so that the green revolution in the traffic field is further promoted. The battery is used as a core component of the new energy automobile, and the performance of the battery directly influences the endurance, the power output and the safety of the whole automobile. In the charge and discharge process of the battery, particularly under the condition of high power output, the battery can generate a large amount of heat, if heat cannot be effectively dissipated in time, the temperature of the battery can be too high, the service life of the battery can be influenced, and serious safety accidents such as fire and explosion can be possibly caused. Therefore, thermal management of batteries is an important technical topic in the development and production of new energy automobiles. Currently, battery thermal management methods commonly used in the market are mainly divided into two categories, namely passive heat dissipation and active heat dissipation. The passive heat dissipation mode reduces the temperature of the battery through the heat conductivity of the battery material and the natural convection of the external environment, and the active heat dissipation mode takes away the heat generated by the battery by means of an air cooling or liquid cooling system in a mechanical or fluid mode, so that the heat dissipation efficiency is improved, the battery is ensured to operate in the optimal working temperature range, and the working efficiency and the safety of the battery are further improved. And the battery protection case plays a very important role therein. Therefore, it is necessary to provide a battery protection box of a new energy automobile with a heat dissipation function.
