Filed:

Jan 31, 2005

Appl. No.:

11/048621

Inventors:

David Winn - Lafayette CA, US
Alfredo Hernandez - San Jose CA, US
Gary Carr - Walnut Creek CA, US

International Classification:

H02P011/00
H02K007/02
H02J009/00

US Classification:

307064000, 363019000, 700287000, 322004000, 322039000

Abstract:

Disclosed is a method and system for providing constant critical AC electrical load with primary, secondary, and in some cases a tertiary source of power with higher reliability and lower operating and capital costs and lower emissions than the traditional utility supply, uninterruptible power supply (UPS), and battery primary power source, and diesel generator back-up systems that are predominately used today. Specifically, the disclosed system utilizes on-site power generation to provide primary power and includes full utility and UPS/DC storage back-up systems.

Appl. No.:

9/088981

David Winn - Lafayette CA

Assignee:

Ericsson Inc - Research Triangle Park NC

International Classification:

H05K 720

US Classification:

361701

Abstract:

A cooling system and method employing separation chutes and baffles is disclosed. The separation chutes separate the cooled air descending from a heat exchanger positioned above heat-generating equipment in an equipment room from heated air ascending from the heat-generating equipment. Separation of the airflows reduces turbulence and increases cooling efficiencies. The separation chutes are made of a variety of materials, both rigid and flexible, for a variety of applications.

International Classification:

F28F 700

US Classification:

165 804

Abstract:

A cooling system employing redundant system components is disclosed. The system includes multiple sets of heat: exchanger units, with each set being in fluid communication with a separate, independently operated fluid pump unit. The heat exchanger units are arranged in at least one row of heat exchanger units. The two sets of heat exchanger units are evenly interspersed with each other along the row of heat exchanger units so that a substantially uniform distribution of cooled air is provided in the event one fluid pump unit fails.

Assignee:

Ericsson Inc. - Research Triangle Park NC

International Classification:

E03B 100

US Classification:

137312

Abstract:

A system, method and apparatus for detecting a fluid leak in a fluid based cooling system and purging the fluid therein under various conditions. The system, method and apparatus detect fluid levels in the cooling system, fluid pressure in the cooling system and fluid spraying and dripping from the cooling system. Upon an affirmative determination of low fluid levels, low fluid pressure or fluid spraying and dripping from one or more locations in the cooling system, the device automatically purges the fluid from the cooling system. Accordingly, in an overhead fluid-based cooling system, any damage to objects below from having fluid leaked thereon is minimized.

International Classification:

F28F 2700
G05D 706
G01M 316

US Classification:

137312

Abstract:

A spray hood device for containing a fluid spray leak in a fluid-based cooling system. A cover member surrounds a given component subject to a fluid spray leak, containing fluid sprays, preventing the fluid sprays from reaching equipment therebelow and minimizing fluid leakage damage.
