Appl. No.:

10/356080

Inventors:

Christian L. Belady - McKinney TX
Christopher G. Malone - Rocklin CA

Assignee:

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

International Classification:

H05K 720

US Classification:

361687, 361683, 361695, 361727, 3123519, 700 9, 248615

Abstract:

A dual-purpose computer according to the invention has a gravity-actuated switch mounted therein or thereon. The gravity-actuated switch is used to control the speed of a cooling fan for the computer. When the computer is operated in a horizontal orientation such as a typical rack-mounted server would be, the gravity actuated switch assumes a first state. When the computer is operated in a vertical orientation such as a typical desk side workstation would be, the gravity actuated switch assumes a second state. When the switch is in the first state, fan speed controller circuitry runs the fan at a first speed. When the switch is in the second state, fan speed controller circuitry runs the fan at a second speed. In one embodiment, the first speed is a higher speed intended to optimize reliability, and the second speed is a lower speed intended to minimize noise.

International Classification:

H05K007/20

US Classification:

165080300, 361704000

Abstract:

A cooling device for electronic devices is built comprising at least two fan sinks thermally coupled together such that when one fan sink fails, the remaining fan sinks are able to compensate for the failed fan sink. Optionally, the remaining fan sinks may be controlled to speed up upon detection of a failure, increasing their cooling capacity to compensate for the failed fan sink. Also optionally, a thermal coupling device such as heat pipes may be used as part of the thermal coupling between the fan sinks to increase the cooling efficiency of the remaining fan sinks to the device or devices closest to the failed fan sink. Also optionally, the thermal coupling device may be configured to allow some flexibility in the cooling device assembly allowing for the cooling of non-coplanar electronic devices.

Appl. No.:

11/370448

Inventors:

Christian Belady - Richardson TX, US
Christopher Malone - Roseville CA, US

International Classification:

G05D 23/00

US Classification:

700300000, 361687000

Abstract:

In one embodiment, a system comprises one or more electronic components, one or more coolant sources, one or more coolant supply lines in fluid communication with the one or more coolant sources, a heat exchanger in thermal communication with the coolant supply lines and the one or more electronic components; one or more coolant distribution units to regulate the flow of coolant through the one or more coolant supply lines, and an environment management unit communicatively coupled to the one or more electronic components and the one or more coolant distribution units, wherein the environment management unit regulates coolant flow through the one or more coolant supply lines according to one or more environmental parameters proximate the one or more electronic components.
