Abstract

An electronic device includes a chassis base and a chassis cover which define an electronic enclosure. The chassis base includes a slant angle venting plate extending at an angle from a chassis base sidewall of the chassis base. The slant angle venting plate has a slant angle vent plate pattern formed therein. Further, the chassis cover includes a chassis cover venting pattern covering the slant angle vent plate pattern. As the slant angle venting plate is slanted, the available surface area in which to form the slant angle vent plate pattern is maximized thus maximizing air flow through the electronic enclosure.

First claim

What is claimed is:

1. An electronic device comprising:
a chassis base comprising:
a chassis base plate;
a chassis base sidewall extending perpendicularly from the chassis base plate, the chassis base sidewall comprising a slant angle venting plate opening, the slant angle venting plate opening being defined by a chassis base sidewall slant angle venting plate edge and slant angle venting plate opening edges extending from the chassis base sidewall slant angle venting plate edge to a chassis cover edge of the chassis base sidewall; and
a slant angle venting plate extending at an angle from the chassis base sidewall, the slant angle venting plate having a slant angle vent plate pattern formed therein; and a chassis cover comprising a chassis cover venting pattern, the chassis cover venting pattern covering the slant angle vent plate pattern.

2. The electronic device of claim 1 wherein the angle is within a range of greater than 90° to less than 180°.

3. The electronic device of claim 2 wherein the angle is within the range of 106.7° to 120.6°.

4. The electronic device of claim 2 wherein the angle is 106.7°.

5. The electronic device of claim 1 wherein the angle is the obtuse angle of intersection between a plane parallel to the chassis base sidewall and a plane parallel to the slant angle venting plate.

6. The electronic device of claim 1 wherein the chassis cover is coupled to the chassis base.

7. The electronic device of claim 1 wherein the chassis base and the chassis cover define an electronic enclosure.

8. The electronic device of claim 7 further comprising an electronic component located within the electronic enclosure.

9. The electronic device of claim 1 wherein the slant angle venting plate is coupled to the chassis base sidewall along the chassis base sidewall slant angle venting plate edge.

10. An electronic device comprising:
a chassis base comprising:
a chassis base sidewall comprising a slant angle venting plate opening; and
a slant angle venting plate extending at an angle from the chassis base sidewall, the slant angle venting plate having a slant angle vent plate pattern formed therein; and

a chassis cover comprising a cover sidewall parallel and directly adjacent to the chassis base sidewall, the cover sidewall comprising a chassis cover venting pattern aligned with the slant angle venting plate opening.

11. The electronic device of claim 10 wherein the slant angle venting plate opening is aligned with the slant angle venting, plate.

12. The electronic device of claim 10 wherein the slant angle venting plate opening is defined by a chassis base sidewall slant angle venting plate edge.

13. The electronic device of claim 12 wherein the slant angle venting plate is connected to the chassis base sidewall along the chassis base sidewall slant angle venting plate edge.

14. The electronic device of claim 13 wherein the slant angle venting plate extends from the chassis base sidewall slant angle venting plate edge to a chassis cover slant angle venting plate edge.

15. The electronic device of claim 14 wherein the chassis cover comprises a cover plate, the chassis cover slant angle venting plate edge being directly adjacent to the cover plate.

16. The electronic device of claim 15 wherein the cover sidewall extends perpendicularly from the cover plate.

17. The electronic device of claim 16 wherein the chassis base comprises a chassis base plate, the chassis base sidewall extending perpendicularly from the chassis base plate.

18. A method comprising:
forming an electronic enclosure with a chassis base and a chassis cover;
generating heat with an electronic component located within the electronic enclosure; and
removing the heat from the electronic enclosure comprising:
causing air to flow through a chassis cover venting pattern in the chassis cover;
causing the air to flow through a slant angle venting plate opening in a chassis base sidewall of the chassis base; and
causing the air to flow through a slant angle vent plate pattern of a slant angle venting plate of the chassis base, the slant angle venting plate extending at an angle from the chassis base sidewall of the chassis base.

19. The method of claim 18 wherein the slant angle vent plate pattern comprises venting perforations.

20. The method of claim 19 further comprising providing electromagnetic interference (EMI) shielding with the venting perforations.
