Electric apparatus having heat radiating fin

摘要

An electric apparatus has a plurality of electric parts (102, 103) and a casing (101) 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 (101) 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 (102, 205, 206) 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 (301) 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. <IMAGE>
