Civil air defense door capable of rapidly dissipating heat

The utility model discloses a civil air defense door capable of dissipating heat quickly, which belongs to the technical field of civil air defense engineering, and is characterized by comprising a door leaf body, a cavity is formed in the door leaf body, a temperature-resistant layer adapting to temperature difference is coated on the inner wall of the cavity, a heat dissipation device is arranged in the cavity, and when the air temperature is high, the heat dissipation device can dissipate heat in the cavity. The multiple cooling fans operate, so that air continuously flows through the cavity, enters the cavity from the air inlet hole in the left side, sequentially passes through the mounting holes in the multiple partition plates and the multiple cooling grooves and then flows out from the air outlet hole in the right side, and therefore large air flow can flow through the interior of the whole cavity evenly without dead corners and can make full contact with the door leaf body; according to the civil air
