Power battery heat dissipation and distribution system

Abstract

The invention discloses a lower battery heat dissipation and distribution system and aims to overcome the defect that the use performance and service life of power batteries are affected due to complex heat dissipation structures of the power batteries of electric vehicles and poor heat dissipation and distribution effects. The system comprises a base and a plurality of battery modules mounted on the base, wherein each battery module comprises multiple vertical cell units; each cell unit comprises a cell, a support and a super heat conducting and transfer assembly, the super heat conducting and transfer assembly is mounted on the corresponding support, heat transfer parts extending out of the support are arranged on front and back sides, the cell is mounted on the support, and the right side surface of the cell is attached to the super heat conducting and transfer assembly; super heat conducting and transfer bodies are mounted on front and back sides of each battery module, the heat transfer parts on front and back sides of each super heat conducting and transfer assembly are attached to the super heat conducting and transfer bodies on front and back sides of the corresponding battery module, one end of each super heat conducting and transfer body is bent to form an L-shaped structure, one end, close to L shapes of the super heat conducting and transfer bodies, of the base is connected with a super heat conducting and collecting bar, and a heat exchange source connected with the super heat conducting and collecting bar is arranged on the base.

Description

technical field [0001] The present invention relates to a power battery, more specifically, it relates to a power battery heat dissipation and heat equalization system. Background technique [0002] As one of the core components of electric vehicles, the performance of power batteries directly affects the performance and safety of electric vehicles. The power battery pack is generally composed of multiple single cells connected in series and parallel, and the structure of the battery system is relatively complicated. The power batteries used in electric vehicles are all chemical power sources, and a certain amount of heat will be released during charging and discharging. If the heat accumulates inside the battery pack and is not dissipated in time, it will lead to excessively high battery temperature and uneven temperature distribution. Chemical power sources generally have an optimal operating temperature range. When the temperature exceeds or falls below the optimal oper...
