Problems solved by technology

The higher the working rate of the battery, the greater the heating power, which limits the working rate of the battery
On the other hand, the existing communication backup power supply module does not consider the fire extinguishing design, if the battery is used improperly, it is very easy to cause a thermal runaway fire

Description

technical field [0001] The invention relates to the technical field of power supply heat dissipation, in particular to the heat dissipation technology in the field of communication backup power supply. Background technique [0002] The communication backup power supply module includes a battery module, a protective board, and a chassis. It is a closed natural heat dissipation device (outdoor application, which requires strict waterproof and dustproof). When the battery is working, it will generate heat, which will heat the battery body, plastic bracket, and the air in the box. , in the end, all the heat will be transferred to the chassis shell first, and then conducted from the shell to the air. [0003] On the heat conduction path between the battery and the outside, the air in the box and the plastic bracket in the middle link will form a large heat conduction resistance. Especially in high temperature climate areas, when the battery is working, the battery heats up quick...
