Abstract

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.

Claims

1. An enclosure for reducing noise of a data storage disk drive device, comprising:

a supporting plate for mounting said data storage disk drive device thereon;

a sound absorption layer formed into an open flat box having opposed side faces and having a slit formed in a front portion of each one of said side faces, whereby so that the data storage read-write device is inserted and the supporting plate passes along the slits; and

a housing having an opening and a slit formed along the side faces thereof, wherein the slit is aligned with the slit of the sound absorption layer so as to receive the hard disk drive along the opening and to pass the side parts of the supporting plate along the slit.

2. The enclosure as claimed in claim 1, further comprising a cover for blocking said opening, wherein at the front surface thereof a hole is formed to be aligned with the cable connectors of the hard disk drive and at rear end of the cover a hook piece is formed to be fit with a hook eye formed at side faces of the housing.

3. The enclosure as claimed in claim 1, further comprising a metal layer coated on the inner wall of the sound absorption layer.

4. The enclosure as claimed in claim 1, wherein the supporting plate is made of a metal sheet and having a bending portion extended from each side thereof, and wherein the width of the supporting plate is much larger than that of the opening of the sound absorption layer so that a part of the bottom portion of the supporting plate is extended outwardly from the hard disk drive through the slits.

5. The enclosure as claimed in claim 4, wherein the bending portion is provided with a plurality of holes for mounting the data storage read-write device to a bracket or a drive bay of the computer housing.

6. The enclosure as claimed in claim 1, wherein the data storage read-write device includes a hard disk drive.

7. The enclosure as claimed in claim 1, wherein the supporting plate constitutes a heat conductive path from the data storage read-write device to the exterior of the sound absorption layer.

8. The enclosure as claimed in claim 1, wherein at front periphery of the sound absorption layer a step portion is formed so as to fit the periphery of the cover into the housing.

9. The enclosure as claimed in claim 1, wherein the sound absorption layer is made of a sound absorptive porous material.

10. A noise-reducing enclosure for blocking disk drive-generated noise, comprising:

a disk drive module;

a mounting member adapted to be attached to said disk drive module and including an extending portion;

a layer of sound absorbing material formed into an open box substantially surrounding said disk drive module and having opposed side faces, wherein a first aperture is formed in each of said opposed side faces for receiving said extending portion therethrough; and

a housing having a pair of opposed sides and defining a front opening for receiving said disk drive module and said layer surrounding said disk drive module, with at least one of said opposed sides of said housing defining a second aperture aligned with one of said first apertures and being adapted to receive said extending portion therethrough;

said extending portion transmitting heat from said disk drive module to outside of said housing and allowing said disk drive module to be mounted to a fixed structure.

11. The enclosure of claim 10, wherein said mounting member comprises a metal alloy.

12. The enclosure of claim 11, wherein said disk drive module has a predetermined width and a predetermined length, said mounting member is a supporting plate having a bottom portion configured for mounting said disk drive module thereto, and said extending portion is a substantially flat plate extending longitudinally for a first dimension equal to a substantial portion of said length and laterally for a second dimension sufficient to mount said supporting plate to a bracket within a disk drive bay of a computer chassis.

13. A noise reducing enclosure for a device that generates noise and heat, comprising:

a device;

a mounting member attached to said device and having an extending portion;

a layer of sound absorbing material formed into an open box substantially surrounding said device and having opposed side faces, wherein a first aperture is formed in each of said opposed side faces for receiving said extending portion; and

a housing having a front opening for receiving said device and said layer surrounding said device, said housing having opposing sides, each having a second aperture formed therein, said second aperture being aligned with said first aperture so that said extending portion passes through said first and second apertures to project outside of said housing;

said extending portion transmitting heat from said device to outside of said housing and allowing said device to be mounted to a fixed structure.

14. The noise reducing enclosure of claim 13, wherein said mounting member comprises a metal alloy.

15. The noise reducing enclosure of claim 13, wherein said device has a side engaged with said mounting member.

16. The noise reducing enclosure of claim 15, wherein said extending portion is a flange bearing a bore that can be fastened to said fixed structure.

17. The noise reducing enclosure of claim 16, wherein said device is a peripheral device for a computer system.

18. The noise reducing enclosure of claim 17, wherein said device is a disk drive module.

19. The noise reducing enclosure of claim 18, wherein said fixed structure is a bay in a computer housing.
