Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of air-cooled energy storage cabinets, and in particular relates to an air-cooled energy storage cabinet with a small battery temperature difference. Background Art
[0002] The cooling process of existing air-cooled energy storage cabinets is that air is discharged through the cold air outlet of the air-cooled energy storage cabinet air conditioner, and then reaches the air-conditioning cabinet of the air-cooled energy storage cabinet through the air guide connecting pipe and is guided to the cold air bin. The cold air flows from the cold air bin downward to each PACK box. The cold air passes through the cold air plate between the batteries to cool the batteries, and then reaches the air duct in the PACK box. The cold air is then exhausted by the PACK box fan to the cavity between the front door and the front end of the PACK box. Finally, it is sucked in by the hot air return vent of the air-cooled energy storage cabinet air conditioner, cooled by the air-cooled energy storage cabinet air conditioner, and discharged cold air, completing a cycle.
[0003] The disadvantage is that the cold air has different paths and lengths from the cold air compartment to each PACK, which ultimately leads to different temperature drops for each battery. The temperature difference between batteries can even be around 8-9 degrees. Utility Model Content
