Embodiment
[0016] see figure 1 and figure 2 .
[0017] A box body for a power battery loading box of an electric vehicle, comprising a box body 10 body and a bottom plate 13, and two ends of the box body body are provided with fishing lugs 12 for fixing the box body 10 and the chassis of the car, and the fishing lugs 12 Several bolt holes 14 are formed on it. Several ribs 1 are formed on the lower surface of the bottom plate 13 for enhancing heat dissipation.
[0018] The rib 1 extends linearly from one axial end of the lower surface of the bottom plate 13 to the other end of the lower surface.
[0019] The rib 1 has a length of 5 mm, a thickness of 1.0 mm, and a gap of 3 mm.
[0020] The method of the present invention is simple in structure and low in cost, but can significantly improve the heat dissipation effect of the air cooling method for the power battery loading box.

Abstract
A heat dissipation structure for a power battery loading box body of an electric vehicle is characterized in that the box body is used for bearing and protecting a power battery of the electric automobile and providing a primary heat dissipation function for the power battery, the box body comprises a bottom plate, and a plurality of ribs used for enhancing heat dissipation are formed on the lowersurface of the bottom plate. The heat dissipation effect of the air cooling mode of the power battery loading box body can be remarkably improved.
Description
technical field [0001] The present invention relates to a battery box for loading new energy vehicles, especially pure electric vehicles or plug-in hybrid vehicles, and more specifically, relates to the heat dissipation structure of the box. Background technique [0002] The working environment temperature of the power battery has an important impact on its life. Under the appropriate temperature conditions, the performance can be fully utilized and the efficiency is the highest. The working power battery will generate a lot of heat, so heat dissipation is a problem that needs to be solved for the box used to load the power battery. Existing commonly used heat dissipation generally adopts liquid cooling and / or air cooling solutions. The way of liquid cooling is generally around the box, usually at the bottom or upper part, where it is in close contact with the battery pack, and a liquid cooling channel is provided. There are also air-cooled methods either alone or at the s...
