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

Embodiment 2

[0044] The technical solution of the present invention is further described in detail in conjunction with specific embodiments. The present invention also discloses a rapid heat dissipation method based on a battery module system of a new energy vehicle, which includes the following steps:

[0045] S1, first-level cooling: after the car is driven, intake air is carried out through the air intake grille, so that the external air is blown into the intake cylinder 31 through the intake cylinder 101 and the intake filter element 102 and pushes the intake turbofan 341 in the intake cylinder 31 Rotate, the intake turbofan 341 generates inertia to keep the intake air, and further the air in the intake cylinder 31 enters the lithium battery box 21 from the air intake box 212 through the bellows 4 to dissipate heat, and finally the lithium battery is discharged by the exhaust turbofan 342. The hot air in the box 21 is extracted;

[0046] S2, two-stage cooling: After the power shaft 37 ...
