Abstract

Certain embodiments of the present invention provide a system for managing heat generated by electronic equipment in an electronic equipment enclosure. The electronic equipment enclosure includes a first pair of equipment rails and a second pair of equipment rails spaced apart from the first pair of equipment rails. The system includes a duct connected to the first pair of equipment rails and a bracket connected to the second pair of equipment rails and spaced apart from the duct. The duct is adapted to receive a first portion of the electronic equipment and the bracket is adapted to receive a second portion of the electronic equipment. The first portion of the electronic equipment includes an air intake opening and the second portion of the electronic equipment includes an air exhaust opening. The duct forms a barrier between the air intake opening and the air exhaust opening for separating cooled air entering the electronic equipment and heated air exiting the electronic equipment.

Claims

1. A system for managing heat generated by electronic equipment in an electronic equipment enclosure, the electronic equipment enclosure comprising a first pair of equipment rails and a second pair of equipment rails spaced apart from the first pair of equipment rails, the system comprising:

a duct connected to the first pair of equipment rails, the duct adapted to receive a first portion of the electronic equipment, the first portion of the electronic equipment comprising an air intake opening; and

a bracket connected to at least one of the second pair of equipment rails and spaced apart from the duct, the bracket adapted to receive a second portion of the electronic equipment, the second portion of the electronic equipment comprising an air exhaust opening,

wherein the duct forms a barrier between the air intake opening and the air exhaust opening for separating cooled air entering the electronic equipment and heated air exiting the electronic equipment.

2. The system of claim 1, wherein the electronic equipment includes a switch.

3. The system of claim 2, wherein the switch includes a fabric extender.

4. The system of claim 1, wherein the duct includes a first opening for receiving the first portion of the electronic equipment.

5. The system of claim 4, wherein the duct includes a guide ramp adjacent the first opening for guiding the first portion of the electronic equipment into the duct.

6. The system of claim 4, wherein the duct includes a seal adjacent the first opening for sealing a gap between the duct and the first portion of the electronic equipment.

7. The system of claim 4, wherein the duct includes a second opening opposite the first opening for accessing the first portion of the electronic equipment.

8. The system of claim 7, wherein the height of the first opening is substantially equal to the height of the electronic equipment.

9. The system of claim 7, wherein the height of the second opening is greater than the height of the first opening.

10. The system of claim 7, further comprising a door rotatably connected to the duct adjacent the second opening.

11. The system of claim 10, wherein the door rotates from an open position to a closed position, the door permitting access to the first portion of the electronic equipment in the open position and restricting access to the first portion of the electronic equipment in the closed position.

12. The system of claim 11, wherein the door includes a latch for securing the door in the closed position.

13. The system of claim 11, wherein the door is perforated so as to permit airflow through the door when the door is in the closed position.

14. The system of claim 1, wherein the duct includes a cable pass-through for routing cables from the first portion of the electronic equipment to the second portion of the electronic equipment.

15. The system of claim 1, wherein the electronic equipment is connected to the bracket.

16. The system of claim 1, wherein the bracket includes a flange for supporting the second portion of the electronic equipment.

17. The system of claim 16, wherein the flange is aligned with a bottom wall of the duct for guiding the first portion of the electronic equipment into the duct.

18. The system of claim 16, wherein the flange includes a guide ramp for guiding the electronic equipment into the bracket.

19. The system of claim 1, wherein the bracket includes a cable tie-down for securing a cable to the bracket.

20. A method for managing heat generated by electronic equipment in an electronic equipment enclosure, the electronic equipment enclosure comprising a first pair of equipment rails and a second pair of equipment rails spaced apart from the first pair of equipment rails, the method comprising:

connecting a duct to the first pair of equipment rails, the duct adapted to receive a first portion of the electronic equipment, the first portion of the electronic equipment comprising an air intake opening; and

connecting a bracket to at least one of the second pair of equipment rails, the bracket spaced apart from the duct, the bracket adapted to receive a second portion of the electronic equipment, the second portion of the electronic equipment comprising an air exhaust opening,

wherein the duct forms a barrier between the air intake opening and the air exhaust opening for separating cooled air entering the electronic equipment and heated air exiting the electronic equipment.
