Abstract

Differing from conventional technology using an installing frame to mount two HDDs on a main board, the present invention provides a housing device consisting of a bottom plate, a top plate, a first circuit board, and a second circuit board for accommodating multi hard disk drives (HDDs). By the disposing of the first circuit board and the second circuit board, two upper row HDDs and two lower row HDDs of the multi HDDs are able to stack on each other; moreover, each of the upper row HDDs and each of the lower row HDDs have an overlap region and a non-overlap region greater than the overlap region. By such arrangements, the four stacked HDDs can dissipate heat normally. In addition, because the upper row HDDs are attached onto the top plate by the bottom surface thereof, it just needs to detach the top plate so as to remove the upper row HDDs from the second circuit board and then inspect the upper row HDDs. Similarly, because the lower row HDDs are attached onto the bottom plate by the bottom surface thereof, it just needs to detach the bottom plate so as to remove the lower row HDDs from the second circuit board and then inspect the lower row HDDs.

Description
