Abstract

The invention pertains to a device for reducing the noise level of, and for cooling, a Component (

1) with moving parts, such as a hard disk in a PC system.

The device comprises a Container (

2) in which Component (

1) is arrayed and in which Ventilation Openings (

4) are provided on opposing sides, through which an air stream can flow for cooling the component.

In accordance with the invention, Component (

1) is completely surrounded by Sound-muting Material (

3) in Container (

2) and Channels (

5) are configured in Sound-muting Material (

3) for adducing and exhausting the cooling air.

Description

Details of the invention are explained by means of an embodiment shown in the drawings.

The drawings show:

in FIG. 1 a cross-section through the device in accordance with the invention, and

in FIG. 2 the section of II—II in FIG.

1.

Claims

1. Device for reducing the noise level of, and for cooling, a Component (

1) with moving parts, comprising:

2. Device according to claim 1, wherein said Cooling Units (

8) are provided on two sides of the Component (

1).

3. Device according to claim 1, wherein each of said at least one Cooling Unit (

8) comprises a Vertical Plate (

9) which is adjacent to the Component (

1), and horizontal Ribs (

10) extending from said Vertical Plate (

9).

4. Device according to claim 3, wherein said at least one Cooling Unit (

8) is tightly surrounded by the Noise-muting Material (

3) on the outsides of top and bottom ones of said Ribs (

10) as well as on the leading edges of the Ribs (

10).

5. Device according to claim 1, wherein a Void (

7) is provided between a top surface of the Component (

1) and said sound-muting Material (

3) as well as between an underside of the Component (

1) and said sound-muting Material (

3).

6. Device according to claim 1, wherein said Ventilation Openings (

4) in the container are arranged opposite one another and in true alignment, and that the air stream flows in a rectilinear direction.

7. Device according to claim 1, wherein at least two of the components are provided to be arranged on top of each other in the Container (

2) and that there is a Void (

6) between any of the components.

8. Device according to claim 7, wherein each of said at least one Cooling Unit (

8) comprises a Vertical Plate (

9) which is adjacent to the Component (

1), and horizontal Ribs (

10) extending from the Vertical Plate (

9), and wherein the ventilation openings are arranged in the area of the Voids (

6,

7) and in the area of Ventilation Spaces (

11) present between the Ribs (

10) of said at least one Cooling Unit (

8).

9. Device according to claim 1, wherein the sound-muting Material (

3) is thicker (D) at an underside of the Component (

1) than at any other sides.

10. Device according to claim 1, wherein the Component (

1) is a hard disk in a PC system.
