Abstract

The invention discloses a battery box for an electric automobile. The battery box comprises an outer box body, a box cover, a cooling disk and a bottom plate, wherein an opening is formed in the top surface of the outer box body, and a hollow containing cavity is formed in the outer box body; the box cover is connected with the top surface of the outer box body in a covering way; the cooling disk and the bottom plate are sequentially connected with the bottom surface of the outer box body; the hollow containing cavity of the outer box body is used for containing at least one battery pack; the cooling disk is a hollow box body of which the bottom surface is opened; locating grooves are formed in the bottom surface of the outer box body; locating convex strips which are matched with and embedded in the locating grooves are arranged on the top surface of the cooling disk; the bottom surface of the cooling disk is covered and sealed through the bottom plate; the hollow box body of the cooling disk is used for carrying out heat conduction cooling on the bottom surface of the outer box body through circulating of a cooling medium. According to the battery box for the electric automobile, provided by the invention, efficient cooling can be realized.

Description

technical field [0001] The invention relates to a box body, in particular to a battery box for an electric vehicle, and belongs to the technical field of electric cabinets. Background technique [0002] With the continuous progress of the times, human beings have higher and higher requirements for environmental quality, and green environmental protection has become a major theme of environmental protection. Among them, expanding the use of electric vehicles and reducing the use of fuel-efficient vehicles is the practice of green environmental protection. Specific measures on a theme. [0003] The battery box is an important part of the electric vehicle, and the structural design of the battery box is directly related to the safe working condition of the battery pack in the box. A traditional battery box generally only includes a box body and a box cover fastened on the box body. The box body includes a bottom plate and side plates, and the inner cavity of the box is used to...
