The invention discloses a heat dissipation structure of a battery pack box body. The heat dissipation structure comprises the battery pack box body and a heat dissipation opening formed in the side face of the battery pack box body. Heat dissipation fan blades are arranged on the inner side face of the air outlet filter screen opening, an inserting connection column is arranged on the side face of the air outlet filter screen opening, external connection rotating fan blades are rotationally connected to the outer side face of the inserting connection column, sweeping strips are arranged on the side face of the external connection rotating fan blades, and the sweeping strips and the external connection rotating fan blades are of an integrated structure. When air flows out of the heat dissipation opening, the external connection rotating fan blades are driven to rotate, meanwhile, the sweeping strips also rotate, brushes on the side faces of the sweeping strips make contact with the surface of the air outlet filter screen opening for brushing, and dust on the surface of the air outlet filter screen opening can be cleaned in time after brushing; therefore, the phenomenon that dust is accumulated and attached to block the filter screen, so that gas is difficult to enter and discharge to influence the heat dissipation efficiency is effectively avoided, and the heat dissipation structure of the battery pack box body is effectively improved.
