Abstract

The invention discloses an air-cooled heat dissipation battery pack. The air-cooled heat dissipation battery pack comprises a battery box body, an air-cooled heat dissipation assembly, a battery management system and a battery module. The battery management system and the battery module are fixed in the battery box body, the battery box body comprises an upper cover plate and a lower box body, theupper cover plate is hermetically connected with the lower box body, and an overhaul plate is embedded in the side wall of the lower box body; and the air cooling heat dissipation assembly comprisesfirst heat dissipation fins, second heat dissipation fins and a fan, the first heat dissipation fins are fixed to the inner surface and the outer surface of the upper cover plate, the second heat dissipation fins are fixed to the inner surface and the outer surface of the maintenance plate, the fan is fixed into the battery box body, and the battery management system is in communication connectionwith the battery module and the fan. The heat dissipation fins are fixed on the inner surface and the outer surface of the battery box body, so that the heat exchange coefficient between air and thebattery box body is increased, the heat exchange and cooling speed is increased, and the heat dissipation efficiency is improved; and the fan enables air to circularly flow in the battery box body toperform forced air-cooling heat dissipation, so that the temperature of the single batteries is more uniform.

Description

technical field [0001] The present invention relates to the field of power batteries, and more specifically, the present invention relates to an air-cooled and heat-dissipating battery pack and a vehicle. Background technique [0002] As the energy source of electric vehicles, the battery pack is the most critical component of electric vehicles, which directly affects the performance of electric vehicles. The temperature is one of the important factors affecting the performance of the battery pack. The battery generates a large amount of heat during operation due to the influence of space and accumulates, causing the temperature of the battery pack to be uneven, thereby affecting the consistency of the single cells of the battery pack. In order to keep the battery pack in the most suitable working condition and to maximize the performance and life of the battery pack, it is particularly important to dissipate heat from the battery. [0003] Air cooling is to use air as a co...
