Electric vehicle battery cooling structure

Abstract

The invention discloses an electric vehicle battery cooling structure, and mainly relates to the field of electric vehicles. The electric vehicle battery cooling structure comprises batteries, a box and an air duct pipe, wherein the box comprises a lower shell and a cover plate; the lower shell is a square shell; the cover plate is fixed above the shell; the cover plate is matched with the lower shell to form the box; an air inlet is formed in the front end of the cover plate; the battery is fixed on the lower shell; the batteries are arranged in columns along the front-rear direction; gaps are arranged between the battery columns; air ducts are formed among the lower shell, the cover plate and the batteries; the air duct pipe is arranged on one side of the rear part of the shell; the airduct pipe is communicated with the inner part of the lower shell and the outer part of a vehicle body; an air door is hinged at the end, far away from the lower shell, of the air duct pipe; the frontend of the air door is hinged with the front end of the air duct pipe; when the air door is closed, the air door is adapted to a metal plate shell of the vehicle body to block the mouth of the air duct pipe; a driving device is arranged on the air door; and the air door is opened and closed through the driving device. The electric vehicle battery cooling structure has the beneficial effect of realizing gas flow through gas pressure difference between the inner and outer parts of the vehicle body in the battery box so as to cool the batteries.

Description

technical field [0001] The invention relates to the field of electric vehicles, in particular to a heat dissipation structure for electric vehicle batteries. Background technique [0002] In an electric vehicle, the battery is an energy supply device. When all batteries are charged and discharged, a certain amount of heat will be generated, especially in the process of high-current charging and discharging. When the temperature is too high, the battery is prone to short circuit, so when driving During the high-speed driving state in the process, the battery needs to be discharged with a large current. At this time, it is basically the state where the battery generates the most heat. Using traditional internal combustion engine heat dissipation structures with complex structures and related components will increase unnecessary energy consumption. Contents of the invention [0003] The object of the present invention is to provide a heat dissipation structure for an electric...
