Air-cooled heat dissipation electric control box structure

The utility model relates to the technical field of electric control equipment, in particular to an air-cooling heat dissipation electric control box structure, which is characterized in that a PCB (printed circuit board) is mounted in a hollow structure inside an electric control box; a mounting groove is formed in the top face, facing the electric cabinet, of the base, and a channel is formed in one side wall of the mounting groove in a penetrating mode. The heat dissipation assembly is arranged in the installation groove and makes contact with the bottom of the PCB. The heat dissipation assembly comprises a plurality of heat dissipation fins which are sequentially stacked in the depth direction of the mounting groove; the heat dissipation copper pipes are evenly distributed in the horizontal direction at intervals, the heat dissipation copper pipes and the heat dissipation fins form a block-shaped heat conduction structure, each heat dissipation copper pipe comprises a heat conduction section and a heat di
