The problems with the two types of energy storage battery cabinets are: (1) the width of the first type of energy storage battery cabinet is relatively large, while the height of the second type of energy storage battery cabinet is relatively large. Both types of cabinets occupy a relatively large space volume when in use; (2) the water-cooling unit of existing specifications can only be integrated into the top of the cabinet, occupying at least 280 mm of the cabinet height. The height of the water-cooling unit from the ground is more than 2 m. After the water-cooling unit has been in operation for 2 to 3 years, the failure rate of the compressor is 2 to 2.5%, the failure rate of the water pump is 1.8 to 2.2%, and the failure rate of the fan is about 2.5%. In some dusty areas, it takes 8 to 10 months to clean the condenser of the water-cooling unit. The water-cooling unit has an outer shell, and the cabinet also has an outer shell. When the water-cooling machine fails or needs to be cleaned of dust, the maintenance worker needs to climb to the top of the 2-meter-high cabinet, open the cabinet cover, and then open the cover of the water-cooling unit for cleaning or maintenance, resulting in very low maintenance efficiency for the workers, inconvenient maintenance operations, and high maintenance costs. To this end, the utility model proposes a novel energy storage battery cabinet in order to solve the above technical problems. Summary of the invention

When in use, the condenser installation room can be oriented to any suitable position in the space, and the lateral space is small; the condenser and the fan are installed inside the condenser installation room, so as not to be restricted by the internal space of the cabinet, the selection of the two is more flexible, which helps to improve the fan Efficiency and reduce the working noise of the fan; the condenser is installed inside the condenser installation room. There is no need to open the door panel for cleaning. You can directly use a water gun to high-pressure wash the outside of the condenser installation room. You can also use rainwater to flush and clean the outside of the condenser installation room, which helps to extend the cleaning time interval of the condenser and greatly reduce the operation and maintenance cost; compared with the traditional structure of the water-cooled unit, the external shell of the water-cooled unit is also removed, and the side panels and door panels are shared with the cabinet body, and the "shell in shell" design is cancelled, which greatly reduces the total mass and manufacturing cost of the energy storage battery cabinet, improves the heat dissipation efficiency of the water-cooled unit, and when the front side components of the water-cooled unit fail, you only need to open the door panel for maintenance, which significantly reduces the maintenance difficulty and maintenance cost of the water-cooled unit.
