Problems solved by technology

[0003] After research, it is found that lithium batteries are installed inside the car in the form of modules, and the heat dissipation device used by the lithium battery module itself is often too simple, just install an exhaust fan on the top of the battery box, or use a cooling plate on the bottom wall of the battery box. Heat dissipation. However, when lithium batteries are working, especially when they are running at high load, they often generate more heat. Traditional exhaust air cannot form effective convection, so that deep heat cannot be discharged. In high temperature weather, The heat dissipation effect of the battery is not good, and continuous heat dissipation cannot be effectively carried out, and too many air-cooled or liquid-cooled devices installed will also cause a large load on itself, resulting in waste of power
