Abstract

A system and apparatus to draw air for cooling an interior surface in a body of a computer device. In one embodiment, an upward-facing intake of a fan means is at least partially positioned vertically under vent means which are attached to and/or incorporated within an upper exterior surface of the body of the computer device. In another embodiment, air from outside the body of the computer device flows through said vent means and flows directly into the portion of the upper vent, where the vent means includes air-permeable, hydrophobic means to reduce liquid intrusion from the flow of air.

Claims

1. A computer device comprising:

a body to define at least in part an interior volume of the computer device, wherein an upper interior surface of the body includes an upper opening to allow a flow of air into the interior volume; and

a fan within the interior volume of the computer device, wherein at least a portion of an upper intake of the fan faces the upper opening, the fan to move air through the interior volume, wherein the flow of air is drawn into the upper intake directly after being drawn through the upper opening and an air-permeable, hydrophobic membrane.

2. The computer device of claim 1, wherein the upper opening is incorporated into a keyboard unit of the computing device.

3. The computer device of claim 1, wherein the upper opening is incorporated into a bezel of the computing device, the bezel adjacent to a keyboard of the computing device.

4. The computer device of claim 1, wherein the upper intake is in contact with an edge of the upper opening.

5. The computer device of claim 4, wherein a lower interior surface of the body includes a lower opening to allow another flow of air into the interior volume, wherein the fan further includes a lower intake in contact with an edge of the lower opening, wherein the fan to move air through the interior volume further includes the fan to draw air into the lower intake directly after being drawn through the lower opening.

6. The computer device of claim 1, wherein the fan further includes a lower intake directly facing a lower interior surface of the interior volume, wherein any air drawn into the lower intake is not directly drawn into the lower intake from any opening in the lower interior surface.

7. The computer device of claim 6, wherein air drawn into the lower intake includes air drawn across the lower interior surface.

8. The computer device of claim 6, further comprising a printed circuit (PC) board, wherein air drawn into the lower intake includes air drawn across a surface of the PC board.

9. The computer device of claim 6, wherein the upper intake is in contact with a structure defining the opening.

10. A computer device comprising:

fan means for moving air through an interior volume of the computer device, wherein an upper interior surface of the interior volume includes an upper opening to allow a vertical flow of air downward into the interior volume; and

an upper intake of the fan means, the upper intake directly facing the upper opening, wherein the fan means for moving air includes means for drawing the vertical flow of air into the upper intake directly after the vertical flow of air being drawn through the upper opening and an air-permeable, hydrophobic membrane.

11. The computer device of claim 10, wherein the upper opening is incorporated into a keyboard unit of the computing device.

12. The computer device of claim 10, wherein the upper opening is incorporated into a bezel of the computing device, the bezel adjacent to a keyboard of the computing device.

13. The computer device of claim 10, wherein the upper intake is in contact with an edge of the upper opening.

14. The computer device of claim 13, wherein a lower interior surface of the body includes a lower opening to allow another flow of air into the interior volume, wherein the fan means further includes a lower intake in contact with an edge of the lower opening, wherein the fan means further includes means for drawing air into the lower intake directly after being drawn through the lower opening.

15. The computer device of claim 10, wherein the fan further includes a lower intake directly facing a lower interior surface of the interior volume, wherein any air drawn into the lower intake is not directly drawn into the lower intake from any opening in the lower interior surface.

16. The computer device of claim 15, wherein air drawn into the lower intake includes air drawn across the lower interior surface.

17. The computer device of claim 15, further comprising a printed circuit (PC) board, wherein air drawn into the lower intake includes air drawn across a surface of the PC board.

18. The computer device of claim 15, wherein the upper intake is in contact with a structure defining the opening.
