Abstract

A method for cooling electronic equipment. The method including propagating air through a first electronic component of the electronic equipment into a first enclosed area, where propagating the air through the first electronic component cools the first electronic component, circulating a refrigerant in a cooling loop, where the cooling loop comprises a heat exchanger, and propagating the air out of the first enclosed area by passing through the heat exchanger into a second enclosed area, where the air is cooled by passing through the heat exchanger.

First claim

What is claimed is:

1. A method for cooling a first electronic component and a second electronic component in a room, comprising:
disposing the first electronic component and the second electronic component in parallel in the room to create an aisle therebetween;
disposing a retractable cap over the first electronic component and the second electronic component without a mechanical connection therebetween, so that the aisle is an enclosed area enclosed by the first and second electronic components and the retractable cap when the retractable cap is in a lowered state,
wherein the retractable cap does not enclose the aisle when the retractable cap is in a raised state, and
wherein the cap extends over but not beyond the first and the second electronic components; and

propagating air through the enclosed area and the first and second electronic component to cool the first electronic component and the second electronic component;
circulating a refrigerant in a cooling loop, wherein the cooling loop comprises a heat exchanger; and
propagating the air, wherein the air is cooled by passing through the heat exchanger,
wherein the heat exchanger is a reversible heat exchanger disposed in the retractable cap to reverse direction of air propagating through the enclosed area,
wherein the retractable cap is supported at a center thereof by a lift mechanism, and
wherein the center is a center between the first electronic component and the second electronic component.

2. The method of claim 1 , wherein the air is propagated from the enclosed area through the first and second electronic components.

3. The method of claim 1 , wherein the air is propagated to the enclosed area through the first and second electronic components.

4. The method of claim 1 ,
wherein the retractable cap comprises a grid,
wherein the heat exchanger is in a first space of a plurality of spaces comprised in the grid, and
wherein at least a portion of the grid encloses at least a portion of the enclosed area.

5. The method of claim 1 , further comprising:
disposing a third electronic component in parallel with second electronic component, forming another aisle therebetween;
retracting the retractable cap from the first and second electronic components; and
disposing the retractable cap over the second electronic component and the third electronic component so that the another aisle is an enclosed area enclosed by the second and third electronic components and the retractable cap.

6. The method of claim 3 , wherein the air is propagated out of the enclosed area and rises through the heat exchanger.

7. The method of claim 6 , wherein the air rises passively through the heat exchanger without the use of an air blowing device.

8. A room comprising:
a first electronic component and a second electronic component disposed in parallel in the room to create an aisle therebetween;
a retractable cap disposed over the first electronic component and the second electronic component without a mechanical connection therebetween so that the aisle is an enclosed area enclosed by the first and second electronic components and the retractable cap when the retractable cap is in a lowered state,
wherein the retractable cap does not enclose the aisle when the retractable cap is in a raised state,
wherein the cap extends over but not beyond the first and the second electronic component; and

a cooling loop;
wherein the first electronic component and the second electronic component are cooled by air propagating through the enclosed area, the first electronic component, and the second electronic component,
wherein the cooling loop circulates a refrigerant,
wherein the cooling loop comprises a heat exchanger,
wherein the air is propagated through the heat exchanger,
wherein the air is cooled by passing through the heat exchanger,
wherein the heat exchanger is a reversible heat exchanger disposed in the retractable cap to reverse direction of air propagating through the enclosed area,
wherein the retractable cap is supported at a center thereof by a lift mechanism, and
wherein the center is a center between the first electronic component and the second electronic component.

9. The room of claim 8 , wherein the air is propagated from the enclosed area through the first and second electronic components.

10. The enclosure of claim 8 , wherein the air is propagated to the enclosed area through the first and second electronic components.

11. The room of claim 8 ,
wherein the retractable cap comprises a grid having a plurality of spaces,
wherein the heat exchanger is in a first space of the plurality of spaces, and
wherein at least a portion of the grid encloses at least a portion of the enclosed area.

12. The room of claim 8 , further comprising:
a third electronic component disposed in parallel with the second electronic component, forming another aisle therebetween; and
another retractable cap disposed over the second electronic component and the third electronic component so that the another aisle is an enclosed area enclosed by the second and third electronic components and the another retractable cap.

13. The room of claim 8 , wherein the air is propagated out of the enclosed area and rises through the heat exchanger.

14. The room of claim 13 , wherein the air rises passively through the heat exchanger without the use of an air blowing device.

15. The room of claim 8 , further comprising:
a third electronic component disposed in parallel with the second electronic component, forming another aisle therebetween,
wherein the retractable cap is configured to be retracted from the first and second electronic components and disposed onto the second electronic component and the third electronic component so that the another aisle is an enclosed area enclosed by the second and third electronic components and the retractable cap.

16. The method of claim 1 , further comprising:
disposing a third electronic component in parallel with the second electronic component, forming another aisle therebetween; and
disposing another retractable cap over the second electronic component and the third electronic component so that the another aisle is an enclosed area enclosed by the second and third electronic components and the another retractable cap.

17. The method of claim 16 ,
wherein the air is propagated from the enclosed area through the first and second electronic components
wherein the air is propagated from the another enclosed area through the second and third electronic components.

18. The room of claim 12 ,
wherein the air is propagated from the enclosed area through the first and second electronic components
wherein the air is propagated from the another enclosed area through the second and third electronic components.

19. The method of claim 1 , wherein the retractable cap contacts the first and second electronic components when lowered and does not contact the first and second electronic components when raised.

20. The room of claim 8 , wherein the retractable cap contacts the first and second electronic components when lowered and does not contact the first and second electronic components when raised.
