Box-type substation box body heat dissipation device

The invention relates to the field of box-type substations, and discloses a box-type substation box body heat dissipation device which comprises a box-type substation box body, a lower shutter, an upper fan and a dustproof net. The lower shutter is installed on a door of the box-type substation box body; a corresponding first ventilation hole is formed in the mounting position of the shutter at the lower part of the door, and a dustproof net is mounted on the inner side of the first ventilation hole; and the upper fan is installed on the side surface of the box-type substation box body, and the box-type substation box body is provided with a corresponding second ventilation hole at the installation position of the upper fan. According to the invention, cold air is sucked in from the position of the lower shutter, hot air is pumped out from the upper fan, a stable airflow channel is formed in the box body of the box-type substation, and air in the box body of the box-type substation naturally circulates and co
