Noise-reducing enclosure for a data storage disk drive

摘要

An enclosure for reducing noise of the data storage read-write device is disclosed. The enclosure preferably contains the hard disk drive. The enclosure includes a flat box type housing 40 having at least one opening and a slit 42 formed along the side faces of the housing 40. Each slit 42 has a predetermined length extending inwardly from the opening and being aligned to face each other. Fitted in the housing 40 is a sound absorption layer 30 surrounding the hard disk drive. This sound absorption layer 30 is formed into a open flat box having a slit 34 formed along the side faces of the sound absorption layer and being aligned with the slit 42 of housing 40. At front periphery of the layer 30 a step portion 36 and a guide groove 38 are formed. A supporting plate 50 is provided for mounting a hard disk drive. The supporting plate 50 is made of a metal sheet and has a bending portion 54 extending from each side thereof. At the bending portion 54 a plurality of mounting holes are provided for mounting the hard disk drive assembly to a bracket or a drive bay of the computer housing. The supporting plate 50 of the invention constitutes a heat conductive path from the hard disk drive 12 to the exterior of the sound absorption layer 30. Furthermore, a cap type front cover 60 is provided to fit in the opening of housing 40. In this arrangement, hard disk drive 12 is first mounted on the supporting plate 50 and then inserted into the sound absorption layer 30 while being inserted through opening 32 and the slits 34. The width of the supporting plate 50 is much larger than that of the opening 32 of the sound absorption layer 30 so that a part of the bottom portion 52 of the supporting plate 52 may extend outwardly from the hard disk drive 12 through the slits 34.
