Abstract

An air flow distribution system for cooling server racks includes at least one server rack partially defining a hot aisle and a cold aisle, a first air foil disposed above the server rack, and a second air foil disposed above the first air foil. The first air foil and the second air foil are configured to receive air from the hot aisle, and to form turbulent wake patterns in the cold aisle partially defined by the server rack. The air flow distribution system may include a convex ceiling member above the second air foil. A corresponding method includes causing air to be directed between a first air foil disposed above a server rack and a second air foil disposed above the first air foil to form turbulent wake patterns in the cold aisle. An electrical enclosure assembly includes a receptacle and a cover member configured as an air foil.

First claim

What is claimed is:

1. An air flow distribution system for cooling server racks, the air flow distribution system comprising:
a first air foil disposed above at least one server rack partially defining a hot aisle and a cold aisle, the first air foil at least partially enclosing a top portion of the at least one server rack;
a second air foil disposed above the first air foil;
an enclosure disposed above the hot aisle; and
at least one air circulation member coupled to the enclosure and configured to direct air flow from the hot aisle over the first air foil and the second air foil to form wake patterns in the cold aisle.

2. The air flow distribution system according to claim 1 , further comprising a ceiling member disposed above the second air foil.

3. The air flow distribution system according to claim 2 , wherein at least a portion of the ceiling member includes a convex surface that interfaces with the air flow from the hot aisle to the cold aisle.

4. The air flow distribution system according to claim 3 , wherein the ceiling member is disposed at least partially downstream of the second air foil.

5. The air flow distribution system according to claim 4 , wherein the first air foil includes a surface that is convex with respect to the air flow, and the second air foil includes a first surface that is concave with respect to the air flow and a second surface that is convex with respect to the air flow.

6. The air flow distribution system according to claim 1 , wherein the at least one air circulation member includes at least one fan.

7. The air flow distribution system according to claim 1 , wherein the first air foil is configured to cover an electrical enclosure receptacle configured to receive at least one cable or a support member for the at least one cable for the at least one server rack.

8. The air flow distribution system according to claim 7 , wherein the first air foil is rotatably coupled between vertical columns to enable access to the at least one cable or a support member for the at least one cable.

9. The air flow distribution system according to claim 8 , wherein the at least one cable includes an electrical cable, a fiber-optic cable, or a combination of an electrical cable and a fiber-optic cable.

10. The air flow distribution system according to claim 1 , further comprising a lighting enclosure assembly configured to receive at least one lighting member configured and disposed to project light, wherein at least a portion of the lighting enclosure assembly forms an extension of the first air foil.

11. The air flow distribution system according to claim 10 , further comprising at least one lighting member disposed in the lighting enclosure assembly.

12. A data center subassembly comprising:
at least one first server rack and at least one second server rack defining a hot aisle between the at least one first server rack and the at least one second server rack;
first air foils disposed above the at least one first server rack and the at least one second server rack, respectively, the first air foils at least partially enclosing top portions of the at least one first server rack and the at least one second server rack;
second air foils disposed above the first air foils, respectively;
an enclosure disposed above the hot aisle; and
at least one first air circulation member coupled to a first portion of the enclosure and at least one second air circulation member coupled to a second portion of the enclosure, the at least one first air circulation member and the at least one second air circulation member configured to direct air flow from the hot aisle over the first air foils and the second air foils, respectively, to form wake patterns.

13. The data center subassembly according to claim 12 , wherein the at least one first air circulation member and the at least one second air circulation member each include at least one fan.

14. The data center subassembly according to claim 12 , further comprising ceiling members disposed above the second air foils, respectively.

15. The data center subassembly according to claim 14 , wherein at least a portion of the ceiling members includes a convex surface that interfaces with the air flow.

16. The data center subassembly according to claim 14 , wherein the ceiling members are disposed at least partially downstream of the second air foils.
