Description

Technical Field

[0001] The utility model belongs to the technical field of PACK boxes and relates to an energy storage PACK box with a circulating cooling function. Background Art

[0002] Energy storage PACK box generally refers to a battery box. Energy storage PACK generally refers to packaging, encapsulation and assembly. For example, two batteries are connected in series and formed into a certain shape according to customer requirements. We call it PACK. In the PACK industry, batteries that are not assembled and can be used directly are often called cells, while finished batteries connected to PCM boards with charge and discharge control functions are called batteries.

[0003] When the existing PACK boxes are combined, the space is relatively narrow and passive heat dissipation is usually adopted, resulting in poor heat dissipation effect. The internal units of the PACK box are close to each other, which makes it difficult for the temperature of adjacent units to dissipate quickly. Long-term high temperature will cause the internal equipment and lines to age faster, posing a safety hazard. Therefore, we propose an energy storage PACK box with circulating cooling function.
