Technical Field

The utility model belongs to the technical field of the battery technique and specifically relates to a radiating component combines radiating group battery structure of plastic casing.

Background

In response to the vigorous development of electric bicycles, electric motorcycles, electric balance vehicles, electric scooters and electric related storage battery application products in the market, the environment for using the battery pack is relatively complex, and an important part of the environment is that the battery pack needs to have an excellent thermal management function. Because the battery pack has no good thermal management structure design, the battery cells are in a high temperature state or a state with an excessively large temperature difference between the battery cells, which leads to a shortened service life of a product applied to the battery pack and a severe reduction in the service life of the battery pack, and in a more severe case, safety problems such as fire, explosion and the like may be caused, and therefore, the battery pack must have an effective thermal management structure design.

Disclosure of Invention

The utility model provides a radiating element combines radiating group battery structure of plastic casing, can make the group battery temperature utilize high-efficient high heat conduction's radiating element to reach effectual group battery temperature rise control and reach the group battery service environment of preferred.

Detailed Description

As shown in fig. 1-4, a battery pack structure with a heat dissipation element combined with a plastic housing for heat dissipation, wherein a battery module 5 of the battery pack is disposed in an insulated battery housing 1; the heat dissipation element is a heat dissipation fin 4 embedded in the bottom surface of the battery shell; the bottom fins of the radiating fins are exposed out of the bottom surface of the battery shell; the battery module is connected with the top surfaces of the heat dissipation fins through a heat conduction structure 6 in the battery shell.

The battery shell comprises an upper cover 2 and a lower cover 3, and the heat dissipation fins are aluminum heat dissipation fins embedded in the bottom surface of the lower cover.

Example (b):

in this embodiment, the battery pack case is made of engineering plastic, the aluminum heat dissipation fins are fixed on the battery pack plastic case by plastic injection molding process combined with the heat dissipation fins, and the fins extend out from the bottom surface of the battery case to enlarge the air contact area, after the battery module is installed and assembled in the case, the heat generated by the battery module in the case can be effectively conducted to the aluminum heat dissipation fins and dissipated out of the case by using heat conducting materials such as heat conducting glue or heat conducting fins as contact and conduction media.

The battery core starts to generate heat in the use process of the battery module, the heat source generated by the battery core is conducted to the contacted battery module shell at the moment, the lower end of the battery module shell conducts the heat to the contacted lower cover of the battery shell through the heat conducting glue, the lower cover of the battery shell can be separated from the metal fin surfaces of the heat radiating fins exposed outside by means of heat convection so as to achieve the heat radiating effect, and as the conduction loss generated by the combination of fewer components is less in the heat radiating process, the better the heat conducting effect is, the heat of the battery core can be quickly radiated from the heat radiating fins.

Other portions of the battery module case may transfer heat to the battery case by air convection, and this portion of heat may also be rapidly dissipated from the heat dissipation fins.
