This invention relates to the field of power distribution cabinet technology, specifically to an outdoor power distribution box for smart grids, comprising a cabinet body and a cabinet door. A bracket is installed on the top of the inner cavity of the cabinet body. Two inflatable structures are symmetrically installed on both sides of the cabinet body. Each inflatable structure includes two base plates, which are symmetrically fixed to the outer side wall of the cabinet body. A rotating plate is provided on one side of each base plate. This invention uses a mercury-driven structure to sense the temperature of the bracket. When the temperature rises, the mercury expands and drives the push rod to press down. Through a large gear and a large toothed rod, the rotating plate unfolds, allowing the folded bag to draw air from the outside, achieving basic air cooling. When the temperature exceeds a critical point, the push release structure is triggered, and the return spring causes the rotating plate to close quickly, forcing high-pressure airflow into the cooling hole for impact cooling. At the same time, the suction force of the electric fan pulls the piston down, pushing the loop tube to contact the surface of the bracket to start liquid cooling. After the temperature drops, each component automatically resets, completing the cyclical alternating heat dissipation.
