Heat dissipation power battery pack used for electric automobile

The utility model discloses a heat dissipation power battery pack used for an electric automobile, which includes a box body, wherein a first heat conductive silicon sheet is pasted on the inner wall of the box body; a battery pack is placed in the box body, and is formed by multiple single battery modules in a closely arranged manner; an insulation epoxy board is placed between every two adjacent single battery modules; and second heat conductive silicon sheets are pasted on two sides of each insulation epoxy board. The heat dissipation power battery pack used for the electric automobile is simple in structure and convenient to operate; the heat conductive silicon sheets are distributed among the single battery modules, so efficient and uniform heat dissipation is realized; and in addition, the heat conductive silicon sheets made of a soft material and the insulation epoxy boards made of a hard material are matched for use, so that the defects of high possibilities of wrinkling and deforming of the silicon sheet per se are overcome, and the use effect is better.
