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 for mounting one or more electronic components, comprising:

(a) a frame structure formed from a plurality of support posts and at least partially enclosed by a plurality of panels, the panels including at least side, top and back panels defining a compartment in which the one or more electronic components are mounted, wherein;

(i) the compartment has a top, a bottom and a rear, and

(ii) the top panel includes an opening therethrough that is rectangular in shape; and

(b) a collapsible exhaust air duct extending upward from the top panel of the compartment, wherein the exhaust air duct is rectangular in cross-section and is disposed in surrounding relation to, and in fluid communication with, the top panel opening, and wherein walls of the exhaust air duct are collapsible against each other;

(c) wherein the exhaust air duct is adapted to segregate hot air being exhausted from the compartment from cool air entering the compartment, thereby improving thermal management of the enclosure; and

(d) wherein the collapsible exhaust air duct is adapted to telescope in length.

2. The electronic equipment enclosure of claim 1, wherein the walls are collapsible while remaining coupled together.

3. The electronic equipment enclosure of claim 2, wherein the collapsible exhaust air duct includes a lower duct section adapted to nest within an upper duct section, each of the duct sections including four side panels that are hinged relative to each other, thereby facilitating the collapse of the exhaust air duct from a use state to a flattened state.

4. The electronic equipment enclosure of claim 3, wherein laterally adjacent air duct panels are connected along their side edges by a hinged corner fitting.

5. The electronic equipment enclosure of claim 4, wherein a corner lock is arranged at each corner of the collapsible exhaust air duct, each corner lock being adapted to couple a corner fitting of the upper duct section with a corresponding corner fitting of the lower duct section so as to maintain the air duct panels in the use state.

6. The electronic equipment enclosure of claim 5, wherein each corner lock includes a main body, a lock plate, and a lock screw.

7. The electronic equipment enclosure of claim 4, wherein each corner fitting extends substantially along the length of each of an edge of a respective panel and an edge of a respective adjacent panel.

8. The electronic equipment enclosure of claim 3, wherein an upper edge of each air duct panel of the upper duct section is flared outward.

9. The electronic equipment enclosure of claim 8, wherein a respective seal is attached to the upper edge of each air duct panel of the upper duct section to limit air escaping from between an upper end of the duct section and a ceiling structure.

10. A collapsible exhaust duct, for an electronic equipment enclosure having a frame structure formed from a plurality of support posts and at least partially enclosed by a plurality of panels, the panels including at least side, top and back panels defining a compartment in which the one or more electronic components are mounted, wherein the compartment has a top, a bottom and a rear, and the top panel includes an opening therethrough that is rectangular in shape, the collapsible duct comprising:

(a) first and second duct sections nestingly arranged relative to one another, each duct section having a plurality of walls, one or more of which walls are collapsible against each other;

(b) wherein the exhaust duct is adapted to extend upward from the top panel of the compartment;

(c) wherein the exhaust duct is rectangular in cross-section;

(d) wherein the exhaust duct is adapted to be disposed in surrounding relation to, and in fluid communication with, the top panel opening;

(e) wherein the exhaust duct is adapted to segregate hot air being exhausted from the compartment from cool air entering the compartment, thereby improving thermal management of the enclosure; and

(f) wherein the collapsible exhaust duct is adapted to telescope in length.

11. The collapsible exhaust duct of claim 10, wherein the walls are collapsible while remaining coupled together.

12. The collapsible exhaust duct of claim 11, wherein the walls of each of the first and second duct sections comprise four side panels that are hinged relative to each other, thereby facilitating the collapse of the exhaust duct from a use state to a flattened state.

13. The collapsible exhaust duct of claim 12, wherein laterally adjacent exhaust duct panels are connected along their side edges by a hinged corner fitting.

14. The collapsible exhaust duct of claim 13, wherein a corner lock is arranged at each corner of the collapsible exhaust air duct, each corner lock being adapted to couple a corner fitting of the first duct section with a corresponding corner fitting of the second duct section so as to maintain the exhaust duct panels in the use state.

15. The collapsible exhaust duct of claim 14, wherein each corner lock includes a main body, a lock plate, and a lock screw.

16. The collapsible exhaust duct of claim 13, wherein each corner fitting extends substantially along the length of each of an edge of a respective panel and an edge of a respective adjacent panel.

17. The collapsible exhaust duct of claim 12, wherein an upper edge of each exhaust duct panel of the uppermost of the first and second duct sections is flared outward.

18. The collapsible exhaust duct of claim 17, wherein a respective seal is attached to the upper edge of each exhaust duct panel of the uppermost of the first and second duct sections to limit air escaping from between an upper end of the duct section and a ceiling structure.
