Data center cooling

1. A system for containing and cooling electronic equipment, the system comprising:

housing means for housing electronic equipment and comprising at least two separate units configured to allow gas to pass through the housing means from a first region to cool the electronic equipment and allow the electronic equipment to expel heated gas to a second region;

enclosure means, coupled to the at least two separate units of the housing means, for enclosing the second region and separating the second region from the first region; and

exhaust means coupled to at least one of the housing means or the enclosure means for exhausting the heated gas out of the second region, the exhaust means comprising cooling equipment;

wherein each of the at least two separate unit and the cooling equipment includes a front face and a back face, and wherein the back face of the cooling equipment faces the back face of at least one of the at least two separate units.

2. The system of claim 1 wherein the cooling equipment is configured to draw the heated gas from the second region into the cooling equipment, cool the heated gas drawn into the cooling equipment to produce cooled gas and provide the cooled gas to the first region.

3. The system of claim 1 wherein the exhaust means comprises a fan coupled to the enclosure means.

4. The system of claim 1 wherein the enclosure means comprises a first panel coupled between the at least two separate units, a second panel coupled between at least two separate units, and a roof panel coupled between the first and second panels and the at least two separate units.

5. The system of claim 4 wherein at least one of the first panel or the second end panel includes a door.

6. The system of claim 4 wherein at least one of the first panel, the second panel, or the roof panel is detachable.

7. The system of claim 1 wherein a first unit of the two separate units includes an uninterruptible power supply to provide power to equipment in at least one other unit of the at least two separate units.

8. A method of containing and cooling electronic equipment, the method comprising:

housing electronic equipment in at least a first rack and a second rack, the first and second racks each having a front face and a back face, at least portions of the first and second racks being configured to allow gas to be drawn in through the respective front faces and to allow heated gas to be expelled through the respective back faces;

collecting heated gas expelled through the portions of the first and second racks in a common area adjacent the back faces of the first and second racks, including substantially containing the heated gas in the common area using at least two end panels coupled to the first and second racks and one roof panel coupled to the at least two end panels and the first and second racks; and

exhausting the heated gas out of the common area.

9. The method of claim 8 further comprising maintaining a first air pressure inside the common area that is substantially equal to a second air pressure outside of the common area.

10. The method of claim 9 further comprising powering the electronic equipment with an uninterruptable power supply housed in one of the first or second racks.

11. The method of claim 8 wherein exhausting the heated gas comprises drawing the heated gas into cooling equipment, the method further comprising:

cooling the heated gas in the cooling equipment; and

providing the cooled gas toward the front faces of the first and second racks.

12. The method of claim 8 wherein exhausting the heated air out of the common area is performed in response to an air temperature in the common area exceeding a threshold level.

13. The method of claim 8 further comprising exhausting the heated gas to an area above the common area.
