Cooling Host Module

1. A cooling host module for providing cooling gas flow in a substantially isolated closed loop for a stand-alone computing device separate from a server rack, the stand-alone computing device comprising a substantially vertical first face having an inlet portion comprising no more than about a lower 33% of a height of the first face for inlet gas flow and a substantially vertical second face opposite the first face for outlet gas flow, the cooling host module comprising: a vertical portion and a horizontal portion, the stand-alone computing device supported by the horizontal portion of the cooling host module; a heat exchanger disposed in the vertical portion of the cooling host module adjacent to the second face of the computing device for cooling outlet gas flow from the stand-alone computing device; a gas flow path in the vertical portion and the horizontal portion of the cooling host module for directing air exiting the heat exchanger into the horizontal portion of the cooling host module beneath the computing device; a gas moving device for moving gas in the gas flow path through the vertical portion of the cooling host module, through the horizontal portion of the cooling host module, and into and through an interior of the stand-alone computing device, wherein negative pressure is maintained in the vertical portion of the cooling host module to draw the outlet gas flow exiting the stand-alone computing device into the vertical portion of the cooling host module; a sealing system at an interface between the second face of the stand-alone computing device and the vertical portion of the cooling host module peripheral to the outlet gas flow, the sealing system ensuring that substantially all the outlet gas flow from the stand-alone computing device enters the cooling host module; and a vent for venting gas flow from a distal end of the horizontal portion of the cooling host module into the inlet portion of the first face of the stand-alone computing device to cool an interior of the stand-alone computing device, wherein the vent comprises an adjustably sized opening that adjusts the gas flow directed towards and into the inlet portion of the first face of the stand-alone computing device.

2. The cooling host module as claimed in claim 1 , wherein the gas moving device comprises a fan.

3. The cooling host module as claimed in claim 1 , wherein the gas comprises ambient air.

4. The cooling host module as claimed in claim 1 , wherein the vent comprises an opening shaped to direct gas flow towards the inlet portion of the first face of the stand-alone computing device.

5. The cooling host module as claimed in claim 1 , wherein the stand-alone computing device comprises one of a mainframe computer, a mid-range computer, and a mini computer.

6. A cooling system coupled with a stand-alone computing device separate from a server rack, the stand-alone computing device comprising a substantially vertical first face having an inlet portion comprising no more than about a lower 33% of a height of the first face for inlet gas flow and a substantially vertical second face opposite the first face for outlet gas flow, the cooling system comprising a cooling host module for providing cooling gas flow in a substantially isolated closed loop, the cooling host module comprising: a vertical portion and a horizontal portion, the stand-alone computing device supported by the horizontal portion of the cooling host module; a heat exchanger disposed in the vertical portion of the cooling host module adjacent to the second face of the computing device for cooling outlet gas flow from the stand-alone computing device; a gas flow path in the vertical portion and the horizontal portion of the cooling host module for directing air exiting the heat exchanger into the horizontal portion of the cooling host module beneath the computing device; a gas moving device for moving gas in the gas flow path through the vertical portion of the cooling host module, through the horizontal portion of the cooling host module, and into and through an interior of the stand-alone computing device, wherein negative pressure is maintained in the vertical portion of the cooling host module to draw the outlet gas flow exiting the stand-alone computing device into the vertical portion of the cooling host module; a sealing system at an interface between the second face of the stand-alone computing device and the vertical portion of the cooling host module peripheral to the outlet gas flow, the sealing system ensuring that substantially all the outlet gas flow from the stand-alone computing device enters the cooling host module; and a vent for venting gas flow from a distal end of the horizontal portion of the cooling host module into the inlet portion of the first face of the stand-alone computing device to cool an interior of the stand-alone computing device, wherein the vent comprises an adjustably sized opening that adjusts the gas flow directed towards and into the inlet portion of the first face of the stand-alone computing device.

7. The cooling system as claimed in claim 6 , wherein the gas moving device comprises a fan.

8. The cooling system as claimed in claim 6 , wherein the vent comprises an opening shaped to direct gas flow towards the inlet portion of the first face of the computing device.

9. The cooling system as claimed in claim 6 , wherein the cooling system is coupled with a computing device comprising one of a mainframe computer, a mid-range computer, and a mini computer.
