Header panel assembly for preventing air circulation above electronic equipment enclosure

1. A hot/cold aisle air containment system, comprising:

a frame structure adapted to be at least partially covered by one or more panels to define an interior space, the frame structure including at least one horizontal member;

at least one electronic equipment enclosure installed at least partially within the frame structure;

a header panel assembly installed between a top of the at least one electronic equipment enclosure and the at least one horizontal member of the frame structure, the header panel assembly including a pair of panels adjustably coupled to one another; and

a pair of fixed brackets independently mounted to the at least one horizontal member, the pair of panels being adjustably coupled to the pair of fixed brackets;

wherein a first of the pair of panels is adjustable horizontally relative to a second of the pair of panels, and wherein the pair of panels, together, is adjustable vertically relative to the pair of fixed brackets such that the header panel assembly is adapted to prevent circulation of air above the at least one electronic equipment enclosure.

2. The hot/cold aisle air containment system of claim 1 , wherein the header panel assembly further includes a first clamp, for retaining the first panel against a first of the pair of fixed brackets, and a second clamp, for retaining the second panel against a second of the pair of fixed brackets.

3. The hot/cold aisle air containment system of claim 1 , wherein each of the pair of fixed brackets is adapted to be mounted to the at least one horizontal member at different mounting locations.

4. The hot/cold aisle air containment system of claim 1 , wherein the first panel is adjustable horizontally, in a telescoping manner, relative to the second panel.

5. The hot/cold aisle air containment system of claim 4 , wherein the first panel includes at least one horizontally-oriented slotted opening adapted to slidably accommodate a fastener on the second panel.

6. The hot/cold aisle air containment system of claim 1 , wherein the header panel assembly further includes at least one seal adapted to be compressed against an adjacent structure.

7. The hot/cold aisle air containment system of claim 6 , wherein the at least one seal is disposed at a side edge of at least one of the pair of panels.

8. The hot/cold aisle air containment system of claim 7 , wherein the adjacent structure is a side retention flange of a fixed bracket mounted to the at least one horizontal member.

9. The hot/cold aisle air containment system of claim 7 , wherein the adjacent structure is another seal disposed at a side edge of a panel of an adjoining header panel assembly.

10. The hot/cold aisle air containment system of claim 6 , wherein the at least one seal is disposed at bottom edges of each of the pair of panels.

11. A hot/cold aisle air containment system, comprising:

a frame structure adapted to be at least partially covered by one or more panels to define an interior space, the frame structure including at least one horizontal member and at least two vertical support posts, the at least one horizontal member being supported at its ends by the vertical support posts;

at least one electronic equipment enclosure installed at least partially within the frame structure and between the vertical support posts such that the at least one horizontal member extends above the at least one electronic equipment enclosure without being supported thereby; and

a header panel assembly, installed between a top of the at least one electronic equipment enclosure and the at least one horizontal member of the frame structure, to prevent circulation of air above the enclosure;

wherein the header panel assembly includes a pair of panels, a first of the pair of panels being adjustable horizontally relative to a second of the pair of panels, and the pair of panels, together, being adjustable vertically relative to the least one horizontal member.

12. The hot/cold aisle air containment system of claim 11 , wherein the header panel assembly further includes a first clamp, for retaining the first panel against a first of the pair of fixed brackets, and a second clamp, for retaining the second panel against a second of the pair of fixed brackets.

13. The hot/cold aisle air containment system of claim 11 , wherein the first panel is adjustable horizontally, in a telescoping manner, relative to the second panel.

14. The hot/cold aisle air containment system of claim 13 , wherein the first panel includes at least one horizontally-oriented slotted opening adapted to slidably accommodate a fastener on the second panel.

15. The hot/cold aisle air containment system of claim 11 , wherein the header panel assembly further includes at least one seal adapted to be compressed against an adjacent structure.

16. The hot/cold aisle air containment system of claim 15 , wherein the at least one seal is disposed at a side edge of at least one of the pair of panels.

17. A hot/cold aisle air containment system, comprising:

a frame structure adapted to be at least partially covered by one or more panels to define an interior space, the frame structure including at least one horizontal member;

at least one electronic equipment enclosure installed at least partially within the frame structure, wherein an opening exists between a top of the at least one electronic equipment enclosure and the at least one horizontal member;

a header panel assembly installed between the top of the at least one electronic equipment enclosure and the at least one horizontal member of the frame structure, the header panel assembly including a pair of panels adjustably coupled to one another; and

wherein a first of the pair of panels is adjustable horizontally relative to a second of the pair of panels to substantially cover a width dimension of the opening, and wherein the pair of panels, together, is adjustable vertically relative to the at least one horizontal member to substantially cover a height dimension of the opening such that the header panel assembly is adapted to prevent circulation of air above the at least one electronic equipment enclosure.

18. The hot/cold aisle air containment system of claim 17 , wherein the first panel is adjustable horizontally, in a telescoping manner, relative to the second panel.

19. The hot/cold aisle air containment system of claim 18 , wherein the first panel includes at least one horizontally-oriented slotted opening adapted to slidably accommodate a fastener on the second panel.

20. The hot/cold aisle air containment system of claim 17 , wherein the header panel assembly further includes at least one seal adapted to be compressed against an adjacent structure.
