Abstract

The invention provides a battery pack air cooling system. The battery pack air cooling system comprises a box body and a fan which is disposed outside the box body and communicated with the interior of the box body by virtue of a guide pipe, wherein an inner cavity of the box body is divided by a first guide plate, a second guide plate and a third guide plate which are arranged in the inner cavity of the box body into a first guide air duct, a battery assembling cavity, a second guide air duct and a third guide air duct, the first guide air duct is communicated with the third guide air duct by virtue of a first guide hole formed at a position adjacent to the bottom end of the first guide plate, the third guide air duct is communicated with the battery assembling cavity by virtue of a third guide hole formed in the third guide plate, and the battery assembling cavity is communicated with the second guide plate by virtue of a second guide hole formed in the second guide plate; and an air outlet of the fan is communicated with the first guide air duct by virtue of the guide pipe, and the second guide air duct is communicated with the exterior by virtue of the guide pipe. The battery pack air cooling system can perform heat dissipation and water resistance for a battery pack, and is relatively homogenous in heat dissipation, simple in structure, and good in heat dissipation effect.

Description

technical field [0001] The invention relates to the technical field of electric vehicle electronic circuits, in particular to a battery pack air cooling system. Background technique [0002] As the energy supply source for electric devices in large-scale equipment such as electric vehicles, motorcycles, and motor boats, during the charging and discharging process of power lithium batteries, the internal chemical side reactions and internal resistance of the battery will generate a lot of heat. In the environment, its charging and discharging performance and working life will be greatly reduced, and it will bring safety hazards to the battery pack. In order to allow the single cells in the battery pack to work within the normal temperature range, the battery pack is generally designed with a heat dissipation system. At present, the air-cooled heat dissipation system used in the power lithium battery pack of domestic electric vehicles generally suffers from poor heat dissipati...
