An electric apparatus has a plurality of electric parts and a casing made of electrically conductive material for accommodating therein or mounting thereon a plurality of electric parts. The casing, which has a cavity therein, is provided with a plurality of projections for radiating heat generated by the electric parts in the cavity. The casing is provided with openings for allowing a heat conductive medium to flow into and out of the casing. Further, an electric apparatus has a plurality of electric parts and a casing made of electrically conductive material for accommodating therein or mounting thereon a plurality of electric parts. The casing is provided with openings for allowing a heat conductive medium to flow into and out of the casing. The casing is provided therein with a partition wall which is made of electrically conductive material for dividing the interior of the casing into a plurality of zones along a direction of a flow of the heat conductive medium.
