US Patent:

7016193, Mar 21, 2006

Filed:

Sep 16, 2003

Appl. No.:

10/663252

Inventors:

Joseph Jacques - Garland TX, US
Hiep Nguyen - Grand Prairie TX, US
Osvalso Garcia - Carrollton TX, US

Assignee:

Cisco Technology, Inc. - San Jose CA

International Classification:

H05K 7/20

US Classification:

361695, 361690, 361694, 16510433, 454184

Abstract:

Techniques for cooling electronics assemblies are provided. A divider, such as an electronic card, is utilized to define flow channels through the chassis of the electronics assembly. The divider is parallel to the electronic cards and air movers, such as fans, can be utilized in a push-pull configuration to cause air to flow and counter-flow through the flow channels to cool the electronic cards.

Appl. No.:

12/114011

Gary K. Chan - Palo Alto CA, US
Hai Ho - San Jose CA, US
Joseph Jacques - Austin TX, US

Assignee:

Cisco Technology, Inc. - San Jose CA

International Classification:

F25B 21/02

US Classification:

62 37, 62 33, 62 36

Abstract:

A voltage regulator is configured to receive an input voltage from a power supply, measure a temperature associated with a heat transfer medium, produce an output voltage to drive a thermo-electric cooler, and vary the output voltage in accordance with changes in the measured temperature. Varying the output voltage results in: 1) extracting of heat from the heat transfer medium when the measured temperature is above a threshold value, or 2) supplying of heat to the heat transfer medium when the measured temperature is below a threshold value. The voltage regulator can cap upper and lower bounds of the output voltage to prevent the thermo-electric cooler from reaching its saturation point. The voltage regulator can be configured to produce an output voltage having reduced voltage ripple.

Appl. No.:

12/958387

Inventors:

Edward Kliewer - Sunnyvale CA, US
Joseph Jacques - Austin TX, US

Assignee:

Cisco Technology, Inc. - San Jose CA

International Classification:

H05K 7/20

US Classification:

36167948, 36167946, 36167949, 3616795, 36167951, 361695

Abstract:

In order to increase the flexibility of the positioning of a stacked computer system within a data center, a removable fan unit is positioned within the computer system. The removable fan unit includes a fan housing that supports a fan electrically connected to a connector extending from a side of the fan housing. The connector of the removable fan unit may be electrically connected to a computer system-side connector in a first orientation to move air through the computer system in a first direction. The connector or another connector of the removable fan unit may be electrically connected to another or the same computer system-side connector in a second orientation to move air through the computer system in a second direction.
