AI Technical Summary

Technical Problem

Traditional heat dissipation methods cannot meet the heat dissipation requirements of energy storage converters, resulting in problems such as insufficient protection level, complicated installation, and high risk of liquid infiltration.

Method used

The modular partition design within the enclosure forms independent energy storage converter and battery pack housings. An independent heat dissipation channel is constructed using the central heat exchange housing, and dual-channel heat dissipation is achieved through heat exchange plates. Combined with sealing protection and integrated structural design, the complex piping and leakage risks of liquid cooling systems are avoided.

Benefits of technology

It achieves efficient heat dissipation for energy storage converters and battery packs, improves the protection level and reliability of the equipment, reduces the size and installation complexity of the equipment, and avoids the risks of condensation and leakage in the liquid cooling system.

Abstract

This application discloses an electrical device and an energy storage system, belonging to the field of energy storage technology. The electrical device includes a housing, an energy storage converter, and a battery pack. The housing has a receiving space and a first partition and a second partition spaced apart within the receiving space. The first partition and the second partition divide the receiving space into a first receiving cavity, a heat exchange receiving cavity, and a second receiving cavity spaced apart in sequence. The first partition has a first vent connecting the first receiving cavity and the heat exchange receiving cavity, and the second partition has a second vent connecting the heat exchange receiving cavity and the second receiving cavity. The energy storage converter is housed in the first receiving cavity, and the battery pack is housed in the second receiving cavity. In other words, this application, while ensuring efficient heat dissipation of the energy storage converter, solves the problems of insufficient protection level, complex installation, and potential liquid penetration risk of traditional heat dissipation technologies through physical isolation, sealed protection, and integrated structural design.
