Enclosure case for hard-disk-drive case

Abstract

An outer enclosure case according to the present invention is substantially flat and rectangular in appearance and accommodates an inner hard-disk-drive case that contains a hard disk and a drive unit and the like for driving the hard disk. The outer enclosure case includes a box-like case body that has an open bottom portion; a cover that mounts over the open bottom portion; acoustic material of a prescribed thickness lining the inner peripheral surfaces of the enclosure case body; a heat-dissipating plate disposed on the inside of the top panel of the enclosure case body; and support members that extend from the heat-dissipating plate inside the enclosure case body so as to support the inner hard-disk-drive case between them. The enclosure case cover, the enclosure case body, the heat-dissipating plate, and the support members are constituted of aluminum or an aluminum alloy and are disposed in contact with the inner hard-disk-drive case in such a way as to dissipate heat. A plurality of parallel grooves are formed lengthwise and/or widthwise along the outer surface of the top panel and/or the outer surfaces of the side panels of the outer enclosure case body such that the cross-section of the top panel and/or the side panels is a heat-dissipating configuration of rectangular protrusions and depressions.
