Abstract

An electronic equipment enclosure system with a side-to-side airflow control system includes an enclosure, having a front, a rear, a top, a bottom and two sides, and a side-to-side airflow control system. The airflow control system includes a side wall disposed adjacent one side of the enclosure, and a manifold disposed adjacent the other side of the enclosure. Electronic equipment having a front, a rear, a top, a bottom and two sides is disposed between the side wall and the manifold. Cooling air is routed into a first of the two sides of the electronic equipment, and heated exhaust air is routed out of a second side of the two sides of the electronic equipment and into the manifold. The side wall prevents the heated exhaust air from mixing with the cooling air at the first side of the electronic equipment.

Claims

1. An electronic equipment enclosure system with a side-to-side airflow control system, comprising:

(a) an enclosure, having a front, a rear, a top, a bottom and two sides;

(b) a side-to-side airflow control system, including;

(i) a side wall disposed adjacent one side of the enclosure, and

(ii) a manifold disposed adjacent the other side of the enclosure; and

(c) electronic equipment disposed between the side wall and the manifold;

(d) wherein the manifold includes;

(i) an outer side wall,

(ii) a front wall,

(iii) a rear wall,

(iv) an inward-facing inlet opening, and

(v) an inward-facing exhaust opening,

(vi) wherein heated exhaust air exits the electronic equipment, then enters the manifold through the inlet opening and then exits the manifold through the exhaust opening.

2. The electronic equipment enclosure system of claim 1, wherein the electronic equipment has a front, a rear, a top, a bottom and two sides, wherein cooling air is routed into a first of the two sides of the electronic equipment, wherein heated exhaust air is routed out of a second side of the two sides of the electronic equipment and into the manifold, and wherein the side wall of the side-to-side airflow control system prevents the heated exhaust air from mixing with the cooling air at the first side of the electronic equipment.

3. The electronic equipment enclosure system of claim 2, further comprising an opening in the top of the enclosure and an exhaust duct on the top of the enclosure and in fluid communication with the interior of the enclosure via the opening.

4. The electronic equipment enclosure system of claim 2, wherein the side-to-side airflow control system is adapted to route heated exhaust air from the manifold through an opening in the top of the enclosure and into an exhaust duct disposed on the top of the enclosure.

5. The electronic equipment enclosure system of claim 1, further comprising at least one adjustable filler panel assembly disposed above the electronic equipment to prevent air from passing from side to side over the electronic equipment, disposed below the electronic equipment to prevent air from passing from side to side under the electronic equipment, disposed above the electronic equipment to prevent air from passing from front to back over the electronic equipment, or disposed below the electronic equipment to prevent air from passing from front to back under the electronic equipment.

6. The electronic equipment enclosure system of claim 1, wherein:

(a) the front and rear walls each include an angled portion, extending substantially the full height of the manifold, for redirecting air striking thereagainst;

(b) the manifold further includes a top wall and a bottom wall;

(c) the inward-facing inlet opening is defined at least partially by the front wall, the top wall, and the bottom wall; and

(d) the inward-facing exhaust opening is defined at least partially by the rear wall, the top wall, and the bottom wall.

7. The electronic equipment enclosure system of claim 6, wherein at least a portion of the air entering the manifold through the inlet opening is redirected by the angled portion of the front wall toward the rear wall.

8. The electronic equipment enclosure system of claim 6, wherein at least a portion of the air traveling from front to back within the manifold is redirected by the angled portion of the rear wall toward the exhaust opening.

9. The electronic equipment enclosure system of claim 6, wherein the manifold further includes an inner mounting post, the inner mounting post opposing the outer side wall.

10. The electronic equipment enclosure system of claim 9, wherein the inner mounting post includes an inwardly-angled portion at the rear thereof.

11. The electronic equipment enclosure system of claim 9, wherein the inward-facing inlet opening is further defined by the front edge of the inner mounting post.

12. The electronic equipment enclosure system of claim 9, wherein the inward-facing exhaust opening is further defined by the rear edge of the inner mounting post.

13. The electronic equipment enclosure system of claim 9, wherein the manifold further includes at least one spacer connecting the inner mounting post to the outer side wall.

14. The electronic equipment enclosure system of claim 13, wherein the at least one spacer is planar in shape.

15. The electronic equipment enclosure system of claim 13, wherein the at least one spacer is angled upwardly to redirect air upward when the air is passing through the manifold from front to rear.

16. An electronic equipment enclosure system with a side-to-side airflow control system, comprising:

(a) an electronic equipment enclosure;

(b) an exhaust duct disposed atop the electronic equipment enclosure; and

(c) panels that define a first plenum in a front region of the electronic equipment enclosure, a second plenum in a first side region of the electronic equipment enclosure, a third plenum in a second side region of the electronic equipment enclosure, and a fourth plenum in a rear region of the enclosure, wherein the second side region is on the opposite side of the enclosure from the first side region;

(d) wherein the first plenum is in fluid communication with the second plenum, the second plenum is in fluid communication with a first side of an equipment mounting location, the third plenum is in fluid communication with a second side of the equipment mounting location, the fourth plenum is in fluid communication with the third plenum and with the exhaust duct, and the second side of the equipment mounting location is on the opposite side of the equipment mounting location from the first side thereof; and

(e) wherein the panels are arranged such that cooling air enters the first plenum, passes from the first plenum into the second plenum, passes from the second plenum through the equipment mounting location and into the third plenum as heated exhaust air, and the heated exhaust air passes from the third plenum into the fourth plenum and from the fourth plenum to the exhaust duct.

17. The electronic equipment enclosure system of claim 16, wherein the third plenum is established by a manifold having an inward-facing inlet opening and an inward-facing exhaust opening.

18. The electronic equipment enclosure system of claim 17, wherein the manifold includes at least one spacer to redirect air when the air is passing through the third plenum.

19. The electronic equipment enclosure system of claim 18, wherein the at least one spacer is planar in shape.

20. The electronic equipment enclosure system of claim 19, wherein the at least one spacer is angled to redirect air upwardly.

21. The electronic equipment enclosure system of claim 16, wherein a rear cover of the electronic equipment enclosure includes one or more perforations to permit cooling air to enter directly into the second plenum.
