Abstract
A housing for accomodating an electronic apparatus including heat-generating parts, in which the surface of a cooling air inlet port in the front or rear side of the housing is formed in arcuate fashion and recessed as viewed from the interior of the housing. As a result, the velocity of air introduced is remarkably reduced thereby improving the heat radiation of the housing.
