Problems solved by technology

In addition, due to the different spatial positions of the battery modules, the temperature environment of the battery modules is also different. If the temperature environment of each battery module cannot be guaranteed to be consistent, the service life of the battery modules will be greatly reduced
Most of the existing heat dissipation structures of power battery packs are not perfect, not only the structure is relatively complex, but also the heat dissipation effect is not very good, and there are even fewer solutions with industrial implementation value

Embodiment Construction

[0013] In order to further explain the technical solution of the present invention, the present invention will be described in detail below in conjunction with the accompanying drawings.

[0014] Such as Figure 1 to Figure 4 As shown, the automobile battery module of the present invention includes a round battery module 4, a fixing device for installing the battery module, a front cover 7, and a rear cover 3, and the fixing device consists of a base 6, a lower bracket 5. The top cover 1 and two upper brackets 2 are composed. The base 6 is provided with an air inlet duct 8 in the same axial direction as the battery module. The air inlet duct 8 is wedge-shaped gradually narrowing from the inlet end to the innermost end. The upper surface of the lower bracket 5, the upper and lower surfaces of the upper bracket 2, and the lower surface of the top cover are all provided with a semicircular groove, and the top surface of the base 6 is provided with a vent 9 communicating with the ...

Abstract

The present invention relates to an automobile battery module. The automobile battery module comprises a round battery module, a fixation apparatus for installing the battery module, a front cover plate and a rear cover plate. The fixation apparatus comprises a base, a lower holding support, a top cover and at least an upper holding support. An air intake channel is arranged inside the base. The top surface of the base, the groove bottoms of the semi-circular grooves of the upper holding support and the lower holding support, and the groove bottom of the semi-circular grooves of the top cover are provided with vents, wherein the vents are communicated with the air intake channel. The round battery module is positioned in a cylinder-shaped cavity, and the gap exists between the round battery module and the cavity wall, wherein the cylinder-shaped cavity is formed by the space between the upper holding support and the lower holding support, and the space between the upper holding support and the top cover. With the automobile battery module of the present invention, the heat dissipation environment of the battery module can be improved, and the service life of the battery module can be increased.

Description

technical field [0001] The present invention relates to parts of new energy automobiles, and more specifically relates to an automobile battery module. Background technique [0002] The automotive battery module is an indispensable component in the power system of a hybrid electric vehicle. The automotive battery module mainly includes a battery module and a fixing device for installing the battery module. Both ends of the battery module are metal pillars with regular hexagonal cross-sections. The structure of the fixing device used to install the battery module occupies a dominant position in the design of the battery module, because the heat dissipation of the battery module will directly affect the key battery performance such as the life and consistency of the battery module. The fixing device of the battery module determines the heat dissipation environment of the battery module. In addition, due to the different spatial positions of the battery modules, the temperat...
