Filed:

Feb 3, 2004

Appl. No.:

10/772115

Inventors:

Cullen E. Bash - San Francisco CA, US
Glenn C. Simon - Auburn CA, US
Christopher G. Malone - Loomis CA, US

Assignee:

Hewlett-Packard Development Company, L.P. - Houston TX

International Classification:

H05K 7/20

US Classification:

361700, 361687, 165 803, 16510433

Abstract:

An enclosure forms a plurality of tiers vertically stacked in a longitudinal dimension. Each tier is a 1U modular computer system having a computer chassis configured for mounting in the multi-tiered support, and computer components that need cooling within the computer chassis. An evaporator is in thermal communication with at least one of the computer components, and vaporizes a coolant to cool that component. A condenser dissipates heat from the coolant vapor, and provides liquid coolant back to the evaporator. The condenser directs liquid coolant gravitationally downward, making the condenser and evaporator gravity driven. An air mover within the chassis cools the condenser, blows air across other components needing cooling, and removes heated air from the chassis.

US Classification:

361699, 361695, 361696, 361697, 174 151, 165 804, 16510433

Abstract:

An enclosure forms a plurality of tiers vertically stacked in a longitudinal dimension. Each tier is a 1U modular computer system having a computer chassis configured for mounting in the multi-tiered support, and computer components that need cooling within the computer chassis. A cold plate is in thermal communication with at least one of the computer components, and convectively removes heat from that component using a liquid coolant. A heat exchanger dissipates heat from the liquid coolant, and provides liquid coolant back to the cold plate. An air mover within the chassis cools the heat exchanger, blows air across other components needing cooling, and removes heated air from the chassis. The air mover may extend substantially across the chassis, or it may blow crosswise from an outlet-ventilating direction.

H05K 5/00

US Classification:

236 493, 622592, 361690, 361695

Abstract:

A cooling system for an electronic system having at least one heat-generating component includes at least one fan and an operation level setting mechanism. The at least one fan is configured to blow air through the electronic system to thereby dissipate heat generated by the heat-generating component. The operation level setting mechanism is configured to set maximum operation level of the at least one fan, wherein the maximum operation level is based on one or more characteristics of the at least one heat-generating component.

Abstract:

A method of providing cooling by a cooling system to a computer data center. The method includes providing a plurality of air-and-water radiators and one or more chillers, the chillers each having a first side in fluid communication with a chilled water loop and a second side in communication with a condenser water loop. The method also includes circulating a first portion of return water coming from the computer data center to a first subset of the air-and-water radiators and through the condenser water loop, circulating a second portion of the return water from the computer data center to a second subset of the air-and-water radiators and through the chilled water loop, and circulating the first portion and the second portion of the return water to the computer data center as cooled supply water.
