This invention relates to the field of distribution boxes, and more particularly to an intelligent explosion-proof distribution box. It includes a mounting frame; a box body connected to the mounting frame; and a protective door installed on the box body. This invention achieves the following: by attaching the installed electrical components to the mounting plate, the mounting plate absorbs the heat from the electrical components, which is then conducted to the fins within the heat dissipation cavity. The airflow formed within the heat dissipation cavity then dissipates heat from the fins and the mounting plate. Simultaneously, the mounting plate separates the box body from the heat dissipation cavity, preventing external airflow from entering the box body during the heat dissipation process. This solves the inherent conflict between heat dissipation requirements and explosion-proof safety in existing outdoor distribution cabinet designs. Furthermore, by using the heat dissipation cavity as the connecting carrier between the box body and the mounting frame, when an electrical component inside the box explodes, the mounting plate and the heat dissipation cavity buffer the residual vibrations from the explosion, reducing the impact of the explosion on the mounting frame.
