[0002] Energy storage batteries mainly refer to batteries used in solar power generation equipment, wind power generation equipment and renewable energy storage. The energy storage battery compartment is a compartment for placing batteries. Batteries placed in the energy storage battery compartment will generate a lot of heat. If the heat is not dissipated quickly, the heat in the energy storage battery compartment will rise rapidly, which is prone to fire and explosion. Therefore, explosion-proof and fire-proof safety measures are required.

[0003] For example, China's patent number CN219610602U is a fireproof and explosion-proof energy storage battery cabin. In this utility model, the heat in the energy storage battery cabin can be dissipated through the cooperation of an exhaust hood, a conveying pipe, a connecting pipe, an exhaust fan and an exhaust pipe. However, the exhaust heat exchange method adopted by the utility model is inefficient and easily affected by the surrounding temperature environment, resulting in low cooling efficiency, which is not conducive to cooling electronic equipment such as high-temperature batteries, thereby affecting the explosion-proof stability and being not conducive to user use. Therefore, a safe and explosion-proof energy storage battery cabin is proposed to solve the above problems. Utility Model Content
