Ventilation system of energy storage prefabricated cabin

The invention relates to the technical field of prefabricated cabins, in particular to a ventilation system of an energy storage prefabricated cabin, which comprises a prefabricated cabin, an air inlet duct is arranged at the bottom of the prefabricated cabin, an air draft duct is arranged at the top of the prefabricated cabin, and ventilation and heat dissipation ports communicated with the air inlet duct and the air draft duct are formed in the top and the bottom of the side wall of the prefabricated cabin. Dustproof baffles are hinged to the ventilation and heat dissipation openings, and the air draft channel comprises a flow guide plate fixed to the prefabricated cabin; compared with the prior art, by arranging the air inlet channel, the air draft channel, the ventilation heat dissipation opening, the first draught fan, the flow guide plate and the heat collection cover in the prefabricated cabin, negative pressure can be generated in the prefabricated cabin, and therefore cold air can enter the prefabric
