Abstract

The invention relates to the technical field of battery thermal management, in particular to a tube-through fin type cylindrical battery module, including a battery sleeve, a cylindrical battery and afin group, the fin group is composed of a plurality of fins arranged in parallel, The fin is provided with an assembly circular hole matched with the battery sleeve, the battery sleeve vertically passes through and is mounted in the assembly circular hole of each fin and is matched with the fin, the inner diameter of the battery sleeve is matched with the outer diameter of the cylindrical battery, and the cylindrical battery is connected end to end in series and installed in the battery sleeve. The invention can solve the problems that the temperature field distribution of a cylindrical battery pack arranged horizontally and connected in series to form a pack is uneven and part of the non-specific area is overheated in the prior art. The battery module has higher specific energy density,and can meet the requirements of good temperature uniformity, temperature control performance and low cost, light weight and manufacturability.

Description

technical field [0001] The invention relates to the technical field of battery thermal management, and specifically relates to a tube-through-fin cylindrical battery module. Background technique [0002] At present, the power battery cells of electric vehicles and energy storage systems mainly have structural forms such as cylindrical batteries, square batteries and pouch batteries. Cylindrical winding battery cells are the earliest, most mature, and most stable lithium-ion batteries. The production process is mature. The standardization, consistency, and safety of batteries are high. The overall cost is also low, and the assembled battery modules have high energy density. , are widely used in electric vehicles and energy storage systems of many companies. [0003] Cylindrical batteries have a small cell capacity and require a large number of cells. Temperature differences are prone to occur inside the battery. It is necessary to strengthen heat dissipation management to im...
