The utility model discloses an explosion-proof motor shell, relates to the technical field of explosion-proof motor shells, and aims to solve the problems that the conventional motor shell is generally made of cast iron, the heat dissipation performance is poor, and the heat conduction performance of the cast iron is poorer than that of other metal materials, so that the heat generated in the motor cannot be better dissipated, and the service life of the motor is prolonged. And the working stability of the motor becomes poor when the motor works in a high-temperature environment for a long time. Comprising a motor outer shell, an aluminum alloy outer layer is arranged in the motor outer shell, and an annular heat transfer copper sheet is bonded to the inner wall of the aluminum alloy outer layer; the heat transfer cylinder is installed in the aluminum alloy outer layer, a heat flow cavity is formed between the heat transfer cylinder and the aluminum alloy outer layer, a plurality of heat dissipation holes are
