Problems solved by technology
[0002] The lithium battery pack is sensitive to the ambient temperature, and the temperature will directly determine the electrical properties and safety of the battery. If the temperature is too high or too low, it will affect the charging and discharging performance of the battery, and the ideal working state cannot be achieved. At the same time, multiple batteries are connected in series and parallel. The internal resistance and capacity of the battery pack will be inconsistent due to the influence of temperature

The invention relates to the technical field of heat dissipation of new energy battery packs, in particular to a heat dissipation structure of a new energy battery pack, which includes a battery pack body, the battery pack body is composed of several battery bodies, and the heat dissipation frame includes a fixed frame and several separators , both ends of the partition are nested in the slots of the fixed frame; the two side walls of the partition are provided with several partition side slots along the length direction; the surrounding walls of the fixed frame are provided with multiple cooling slots , the heat dissipation slot is mainly composed of a plurality of convex lines and a plurality of grooves, the four corners of the surface of the fixed frame are provided with corner holes; the surface of the fixed frame is provided with cooling holes matching the convex lines. When using the present invention, it can not only play a fixed role, but also absorb the heat of the battery body, avoid the battery body from affecting the charging and discharging performance due to excessive temperature, and then ensure that the ideal working state is achieved, and at the same time avoid the battery body from being overheated due to excessive temperature. And there is a phenomenon of inconsistent internal resistance and capacity.
Description
technical field [0001] The invention relates to the technical field of heat dissipation of a new energy battery pack, in particular to a heat dissipation structure of a new energy battery pack. Background technique [0002] The lithium battery pack is sensitive to the ambient temperature, and the temperature will directly determine the electrical properties and safety of the battery. If the temperature is too high or too low, it will affect the charging and discharging performance of the battery, and the ideal working state cannot be achieved. At the same time, multiple batteries are connected in series and parallel. The internal resistance and capacity of the battery pack will be inconsistent due to the influence of temperature. [0003] Therefore, it is necessary to provide a novel heat dissipation structure for the existing lithium battery pack. Contents of the invention [0004] The object of the present invention is to provide a heat dissipation structure of a new en...
