Abstract
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.
Description
Technical field
The utility model relates to the electric automobile power battery technology, relates in particular to a kind of used for electric vehicle heat-radiation dynamic cell group.
Background technology
The lithium-ion-power cell group is the core component of electric automobile, the good and bad quality that directly influences vehicle performance of its performance.But lithium-ion-power cell can produce a large amount of heats in charge and discharge process, owing to be subjected to the limitation of Battery case inner space, heat can not in time distribute, cause that battery temperature raises, thereby accelerated cell degradation, reduce battery performance, even phenomenons such as burning, blast may occur, influenced vehicle performance.Therefore, the heat dispersion of raising battery pack is the key factor that promotes vehicle performance.
At present, existing electrokinetic cell producer adopts the simplest air cooling way to dispel the heat, namely by the fan that is installed on the casing heat of battery pack inside is taken away, the shortcoming of this radiating mode is battery pack local temperature skewness, the uneven consistency that directly influences cell of temperature, and then the serviceability of reduction battery pack.
The utility model content
At the shortcoming of prior art, the utility model provides a kind of simple in structure, uniform electric automobile power battery group of heat radiation.
For achieving the above object, technical solutions of the utility model are as follows:
A kind of used for electric vehicle heat-radiation dynamic cell group, it is characterized in that: comprise casing, post the first thermal conductive silicon film on the cabinet wall, in casing, be placed with battery pack, described battery pack is closely rearranged by a plurality of cell modules, all be placed with the insulating epoxy plate between each adjacent monomer module, the two sides of insulating epoxy plate is pasted with the second thermal conductive silicon film.
Described a kind of used for electric vehicle heat-radiation dynamic cell group is characterized in that: the size of described insulating epoxy plate and battery module coupling, thickness is between the 0.3mm to 1.5mm.
Described a kind of used for electric vehicle heat-radiation dynamic cell group is characterized in that: the described second thermal conductive silicon film single face gum directly sticks on insulating epoxy plate surface.
Compared with prior art, advantage of the present utility model is:
Of the present utility model simple in structure, easy to operate, the thermal conductive silicon film is dispersed between each battery module, can quickly and evenly heat be conducted; In addition, thermal conductive silicon film and rigid insulation epoxy plate that material is softer are used, and have overcome the easily shortcoming of fold, distortion of silica gel sheet itself, have improved its result of use.
