Heat dissipation shell and controller based on heat dissipation shell

The utility model relates to a heat radiation housing. The heat radiation housing comprises an upper housing and a lower housing connected with the upper housing. The upper shell comprises an upper shell body, first heat dissipation holes penetrating through the upper shell body, heat dissipation fins connected with the upper shell body into an integrated structure, and a heat dissipation fan located on the side wall of the upper shell body. The cooling fan and the cooling fins are oppositely arranged, and the air outlet direction of the cooling fan is parallel to the distribution direction ofthe cooling fins; the lower shell comprises a lower shell body and second heat dissipation holes penetrating through the lower shell body. Correspondingly, the utility model further provides a controller based on the heat dissipation shell. According to the heat dissipation shell provided by the utility model, through the design of the heat dissipation fins and the heat dissipation fans and the design of the heat dissipa
