[0002] Currently, commonly used liquid-cooled cabinet testing devices for energy storage systems are mostly used in normal indoor and outdoor environments with normal temperatures. While these devices can ensure the functionality and normal energized operation of the internal systems of the energy storage cabinet, they cannot meet the requirements of special environmental conditions, such as outdoor environments at -40°C in extremely cold regions. Furthermore, they cannot guarantee the functionality and normal energized operation of the instruments and accessories within the energy storage cabinet.

[0003] Patent application CN117335285A discloses a modular liquid-cooled energy storage cabinet structure, including a cabinet assembly. The cabinet assembly includes a channel steel base and a base plate. The base plate is placed on top of the channel steel base and fixed with bolts. A front frame and a rear frame are connected to the upper end of the channel steel base, and the front and rear frames are fixedly connected to the base plate. A top plate is connected to the upper end of the front and rear frames, and a top cover is fixedly connected to the upper end of the top plate. Two side plates are connected between the front and rear frames. A partition assembly includes a lower partition and an upper partition. The lower partition is connected to the upper side of the base plate and fixedly connected to the side walls of the front and rear frames. This modular liquid-cooled energy storage cabinet structure can effectively solve problems such as high production difficulty, low welding precision, and difficult transportation of energy storage cabinets, preventing paint damage and deformation during transportation. However, the disclosed structure does not improve the thermal insulation performance of the cabinet. Utility Model Content
