Abstract

A storage device includes a first portion including drive media, and a second portion. The second portion includes a first end wall that is in physical communication with first and second side walls, and a second end wall that is in physical communication with the first and second side walls. The second portion also includes a printed circuit board mounted within the cavity, a plurality of ribs within the cavity, and an air channel within the cavity. The air channel has a lower air flow impedance than other portions of the storage device including the first portion, the printed circuit board, and the ribs. The air channel extends along a direction between the first end wall and the second end wall of the storage device.

First claim

What is claimed is:

1. A storage device comprising:
a first portion including drive media; and
a second portion in physical communication with the first portion, the second portion including:
a first end wall that is in physical communication with first and second side walls;
a second end wall that is in physical communication with the first and second side walls, wherein the physical communication between the first and second end walls and the first and second side walls form a cavity in the second portion;
an air channel within the second portion, wherein the air channel has a lower air flow impedance than other portions of the storage device including the first portion, and other parts of the second portion other than the air channel; and
a plurality of ribs within the cavity, wherein the air channel is formed via a cutout portion in the second end wall being aligned with a cutout portion in a subset of the ribs.

2. The storage device of claim 1 , further comprising:
a printed circuit board in physical communication with the second end wall and the first side wall, wherein the printed circuit board extends from the first side wall toward the second side wall, wherein an end of the printed circuit board that is opposite of the first wall ends a predetermined distance from the second side wall, and the air channel is defined by the predetermined distance between the printed circuit board and the second side wall.

3. The storage device of claim 2 , wherein the second portion further includes:
a gasket in physical communication between a surface of the second portion and the printed circuit board, wherein the air channel extends within the gasket and in between the printed circuit board and the surface of the second portion.

4. The storage device of claim 3 , wherein the gasket has a high porosity to enable air flow of the storage device to flow through the gasket.

5. The storage device of claim 1 , wherein the storage device is configured to be inserted into a front of an information handling system.

6. An information handling system comprising:
a storage device carrier configured to be inserted within a chassis of the information handling system, the storage device carrier including:
a front panel having a first surface and a second surface; and
a first air channel extending from the first surface to the second surface; and

a storage device configured to be placed in physical communication with the storage device carrier, the storage device including:
a first portion including drive media; and
a second portion in physical communication with the first portion, the second portion including:
a first end wall that is in physical communication with first and second side walls;
a second end wall that is in physical communication with the first and second side walls, wherein the first and second end walls and the first and second side walls form a cavity in the second portion; and
a second air channel within the cavity, wherein the second air channel has a lower air flow impedance than other portions of the storage device including the first portion, and other parts of the second portion other than the second air channel.

7. The information handling system of claim 6 , wherein the second portion further includes:
a plurality of ribs within the cavity, wherein the second air channel is formed via a cutout portion in the second end wall being aligned with a cutout portion in a subset of the plurality of ribs.

8. The information handling system of claim 6 , further comprising:
a printed circuit board is in physical communication with the second end wall and the first side wall, wherein the printed circuit board extends from the first side wall toward the second side wall, wherein an end of the printed circuit board that is opposite of the first wall ends a predetermined distance from the second side wall, and the second air channel is defined by the predetermined distance between the printed circuit board and the second side wall.

9. The information handling system of claim 8 , wherein second portion further includes:
a gasket in physical communication between a surface of the second portion and the printed circuit board, wherein the second air channel extends within the gasket and in between the printed circuit board and the surface of the second portion.

10. The information handling system of claim 9 , wherein the gasket has a high porosity to enable air flow of the storage device to flow through the gasket.

11. The information handling system of claim 6 , wherein the air channel extends along a direction between the first end wall and the second end wall of the storage device.

12. The information handling system of claim 6 , wherein the storage device carrier and the storage device are configured to be inserted into a front of the information handling system.

13. An information handling system comprising:
a cooling fan to draw air through the information handling system;
a storage device carrier configured to be inserted within a chassis of the information handling system, the storage device carrier including:
a front panel having a first surface and a second surface; and
a first air channel extending from the first surface to the second surface; and

a storage device configured to be placed in physical communication with the storage device carrier, the storage device including:
a first portion including drive media; and
a second portion in physical communication with the first portion, the second portion including:
a first end wall that is in physical communication with first and second side walls; and
a second end wall that is in physical communication with the first and second side walls, wherein the physical communication between the first and second end walls and the first and second side walls form a cavity in the second portion.

14. The information handling system of claim 13 , further comprising:
a plurality of ribs within the cavity; and
a second air channel within the cavity, wherein the first and second air channels have lower air flow impedance than other portions of the storage device carrier and the storage device including the front panel, the first portion, and the ribs, wherein the second air channel extends along a direction between the first end wall and the second end wall of the storage device, wherein the cooling fan draws the air through the first and second air channels.

15. The information handling system of claim 14 , wherein the second air channel is formed via a cutout portion in the second end wall being aligned with a cutout portion in a subset of the plurality of ribs.

16. The information handling system of claim 13 , further comprising:
a printed circuit board is in physical communication with the second end wall and the first side wall, wherein the printed circuit board extends from the first side wall toward the second side wall, wherein an end of the printed circuit board that is opposite of the first wall ends a predetermined distance from the second side wall, and the second air channel is defined by the predetermined distance between the printed circuit board and the second side wall.
