Abstract

An electronic equipment enclosure includes a frame structure at least partially enclosed by a plurality of panels defining a compartment in which one or more electronic components are mounted and an exhaust air duct that is adapted to segregate hot air being exhausted from the compartment from cool air entering the compartment, thereby improving thermal management of the enclosure. The exhaust duct includes a lower duct section extending upward from the top panel of the compartment and an upper duct section telescoping upward from an upper end of the lower duct section. Each duct section includes four panels connected together by hinged corner fittings such that the section is collapsible. The upper duct section includes an outwardly flared portion.

Claims

1. An electronic equipment enclosure comprising:

a frame that defines an at least partially enclosed space; and

a vertical exhaust duct arranged at a top of the frame and configured to convey heated air from the at least partially enclosed space to an area external to the at least partially enclosed space, the vertical exhaust duct including;

a first exhaust duct section; and

a second exhaust duct section vertically translatable relative to the first exhaust duct section;

wherein at least one of the first and second exhaust duct sections is in fluid communication with the at least partially enclosed space; and

wherein one of the first and second exhaust duct sections includes an aperture that is selectively alignable with any of a plurality of vertically-arranged apertures of the other exhaust duct section so as to accommodate a fastener extending through both exhaust duct sections, thereby fixing a vertical height of the vertical exhaust duct.

2. The electronic equipment enclosure of claim 1, wherein the vertical exhaust duct is disposed toward a rear of the top of the frame.

3. The electronic equipment enclosure of claim 1, wherein each of the first and second vertical exhaust duct sections includes four generally planar duct panels.

4. The electronic equipment enclosure of claim 1, wherein each of the first and second vertical exhaust duct sections has a generally rectangular cross-sectional shape.

5. The electronic equipment enclosure of claim 1, wherein the apertures of the plurality of vertically-arranged apertures are evenly spaced.

6. The electronic equipment enclosure of claim 1, wherein at least one of the first and second exhaust duct sections is composed of a self-supporting material.

7. An electronic equipment enclosure comprising:

a frame at least partially enclosed by a plurality of panels to define a compartment;

one or more electronic components stored in the compartment; and

a vertical exhaust duct comprising;

a first exhaust duct section arranged at a top panel disposed atop the frame, the first exhaust duct section being in fluid communication with an interior of the compartment; and

a second exhaust duct section vertically translatable relative to the first exhaust duct section for adjustment of a vertical height of the vertical exhaust duct;

wherein one of the first and second exhaust duct sections includes an aperture that is selectively alignable with any of a plurality of vertically-arranged apertures of the other exhaust duct section so as to accommodate a fastener extending through both exhaust duct sections, thereby fixing the vertical height of the vertical exhaust duct.

8. The electronic equipment enclosure of claim 7, wherein the vertical exhaust duct is disposed toward a rear of the top panel.

9. The electronic equipment enclosure of claim 7, wherein each of the first and second vertical exhaust duct sections includes four generally planar duct panels.

10. The electronic equipment enclosure of claim 7, wherein each of the first and second vertical exhaust duct sections has a generally rectangular cross-sectional shape.

11. The electronic equipment enclosure of claim 7, wherein the apertures of the plurality of vertically-arranged apertures are evenly spaced.

12. The electronic equipment enclosure of claim 7, wherein at least one of the first and second exhaust duct sections is composed of a self-supporting material.

13. An electronic equipment enclosure comprising:

a frame that defines an at least partially enclosed space; and

a vertical exhaust duct arranged at a top of the frame and configured to convey heated air from the at least partially enclosed space to an area external to the at least partially enclosed space, the vertical exhaust duct including;

a first exhaust duct section; and

a second exhaust duct section vertically translatable relative to the first exhaust duct section;

a seal structure arranged along an upper edge of the vertical exhaust duct so as to be deflectable by an adjacent structure, thereby closing an air gap between the vertical exhaust duct and the adjacent structure.

14. The electronic equipment enclosure of claim 13, wherein the seal structure is at least partially flexible so as to permit abutment against an uneven surface.

15. The electronic equipment enclosure of claim 13, wherein the seal structure includes a pair of fingers that define a channel for receiving the upper edge of the vertical exhaust duct.

16. The electronic equipment enclosure of claim 13, wherein the vertical exhaust duct is disposed toward a rear of the top of the frame.

17. The electronic equipment enclosure of claim 13, wherein each of the first and second vertical exhaust duct sections includes four generally planar duct panels.

18. The electronic equipment enclosure of claim 13, wherein each of the first and second vertical exhaust duct sections has a generally rectangular cross-sectional shape.

19. The electronic equipment enclosure of claim 13, wherein at least one of the first and second exhaust duct sections is composed of a self-supporting material.
