[0002] Energy storage cabinets, also known as energy storage systems or battery energy storage systems, are a type of equipment or device used to store electrical energy. According to the application field, they can be divided into industrial and commercial energy storage cabinets, household energy storage cabinets, and grid-level energy storage cabinets / container-type energy storage, etc. In the prior art, in order to improve the safety of the use of energy storage cabinets, a heat dissipation structure is usually provided on the energy storage cabinet, but the heat dissipation structure is mostly aimed at the battery compartment part of the energy storage cabinet for heat dissipation, while ignoring the heat dissipation requirements of the electrical compartment part. According to statistics, the internal temperature of electrical equipment in the electrical compartment (such as PCS, liquid cooling units) can reach as high as 80℃-90℃ or above during operation.
