Air-cooling system for automobile power supply

Abstract

The invention discloses an air-cooling system for an automobile power supply and relates to the field of electric cars. The air-cooling system comprises a battery base, a battery cover which is fixed on the battery base and can be detached, and a plurality of battery modules fixed on the battery base; the battery modules are positioned on the inner side of the battery cover; a plurality of air collection devices are arranged on the front side of the battery base and take the shapes of trumpets with running-through interiors; the big mouths of the air collection devices face a car running direction; a plurality of air inlets are formed in the battery base in a penetrating manner; the upper ends of the air inlets are communicated with the inner side of the battery cover; the lower ends of the air inlets are connected with the small mouths on the rear sides of the air collection devices through connecting pipes; each air collection device is communicated with at least one of the air inlets; and a heat dissipation opening is formed in the battery cover. According to the air-cooling system for the automobile power supply, the effects from of an air source on the different battery modules inside are equal, all the battery modules can well dissipate heat, and the battery performance is guaranteed.

Description

technical field [0001] The invention relates to the field of electric vehicles, in particular to a vehicle power supply air cooling system for electric vehicles. Background technique [0002] As people's awareness of environmental protection gradually strengthens, electric vehicles are gradually becoming popular, and power modules and power systems for electric vehicles and other fields are constantly being developed and improved. In view of the current continuous promotion and use of electric vehicles, considering the limitations of power supply systems in high or low temperature conditions and the reliability of battery cells, the heat dissipation and heating functions of power supplies have attracted more and more attention. Therefore, people try to solve the heat dissipation and heating problems of the power module by improving some battery pack equipment. For example, the patent authorization announcement number is CN202009061U, and the authorization announcement date i...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the problem that the air source of the air-cooled system of the vehicle power supply has unequal effects on the different internal battery modules, some battery modules have poor heat dissipation effect, and it is easy to cause uneven heat dissipation in the battery pack and affect the performance of the battery. The effect of the air source on different internal battery modules is relatively equal, all battery modules can dissipate heat better, and the vehicle power supply air cooling system guarantees battery performance
