Cooling battery module

Abstract

The invention relates to a heat dissipation battery module, comprising a metal shell, at least one battery core and an elastomer, wherein the metal shell is peripherally provided with an accommodation space, one side of the accommodation space is an open mouth provided with a top cover which has a plurality of cutting slots; the battery cores are disposed in the accommodation space; the top of each battery core is provided with a positive electrode polar tab and a negative electrode polar tab which penetrate out of the cutting slots; and the elastomer is inserted in one side of the battery core and abuts against the battery core, so that the battery core is abutted the metal shell in a large area, and the heat dissipation battery module can complete an effect of rapid heat dissipation.

Description

technical field [0001] The invention relates to a heat dissipation battery module, especially a heat dissipation battery module suitable for use in electronic devices. Background technique [0002] Electronic products bring many conveniences to people in life, especially related products such as portable electronic products or electric vehicles. In order to make these electronic or electrical products work normally, the existence of batteries is very important. Moreover, as users rely on electronic products for a longer period of time, the battery's usable power life also needs to increase. To meet this demand, and at the same time be environmentally friendly, high-efficiency rechargeable batteries can best meet the demand. [0003] Inevitably, during the charging or discharging process of high-efficiency rechargeable batteries, the internal battery materials (such as lithium electrons) will generate a lot of heat when ion exchange occurs, resulting in an increase in the int...

[0003] Inevitably, during the charging or discharging process of high-efficiency rechargeable batteries, the internal battery materials (such as lithium electrons) will generate a lot of heat when ion exchange occurs, resulting in an increase in the internal operating temperature, thereby generating thermal resistance. effect, thereby lowering the working efficiency of charging or discharging. Therefore, in order to keep its working temperature stable, the heat dissipation countermeasure of the battery has undoubtedly become an important key to the battery's power efficiency.

However, the current battery structure is provided with a battery core installed inside the body, the heat generated by the battery core is directly conducted to the body, and then the body and the outside air perform heat exchange for heat dissipation, but the battery core and The fit of the main body is a loose fit. Although there is air flow in contact with the outer surface of the main body for heat exchange during use, the contact area between the battery core and the main body is limited, so the efficiency of heat exchange is insufficient, resulting in subsequent heat accumulation. It is inside the battery body, causing the internal working temperature and thermal resistance to rise continuously, seriously affecting its charging or discharging performance, which is not ideal
