Abstract

The invention relates to an electric vehicle annular forced air-cooled heat dissipation parallel battery module and application thereof. The electric vehicle annular forced air-cooled heat dissipation parallel battery module comprises a battery module box body, a battery module box cover and a battery module core; the battery module box body is internally provided with a first air duct wall and a second air duct wall; ventilation holes are formed in the first air duct wall and the second air duct wall respectively; the battery module core is arranged between the first air duct wall and the second air duct wall; a first air duct is arranged between the first air duct wall and the inner side wall of the battery module box body; the inner side wall of the second air duct wall is a second air duct; the top end of the second air duct is connected with the battery module box cover; the bottom end of the second air duct is provided with a heat dissipation fan; and a plurality of standard electrical cores are arranged on the battery module core. The electric vehicle annular forced air-cooled heat dissipation parallel battery module changes the traditional battery module layout mode, adopts a novel layout mode to carry out mounting, improves the forced air cooling effect and ensures each single standard electrical core to have the same heat dissipation effect, so that the purpose of effectively dissipating heat is reached, the problem of uneven heat dissipation of the battery module is also solved, and normal running of the battery module is effectively guaranteed.

Description

technical field [0001] The invention relates to an electric vehicle annular forced air cooling and heat dissipation parallel battery module and an application thereof, belonging to the technical field of electric vehicle power battery heat management. Background technique [0002] At present, new energy vehicles are developing rapidly, especially the development of pure electric vehicles is changing with each passing day. As the core component of pure electric vehicles, power batteries have become a major obstacle to the development of pure electric vehicles due to their slow development. The heat dissipation of power batteries is one of the main problems in the development of power batteries. [0003] In practical applications, air cooling is the main heat dissipation method for power batteries. With the continuous improvement of the performance of pure electric vehicles, the air-cooled heat dissipation method of power batteries has changed from natural air cooling to for...
