Filed:

Jan 23, 1995

Appl. No.:

8/376769

Inventors:

Ralph I. Larson - Bolton MA
Richard J. Phillips - Alachua FL
Alan F. Beane - Gilford NH

Assignee:

Aavid Laboratories, Inc. - Laconia NH

International Classification:

F25D 2312

US Classification:

622592

Abstract:

A two-phase cooling system for a portable computer, the system consisting of an evaporator and a condenser that are both included in either the lid or the base of the computer. The two-phase cooling system is positioned proximate to the computer's heat-producing circuitry, such that the system draws liquid coolant past the circuitry and heat is transferred from the circuitry to the coolant. A fan may also be included, to assist in heat rejection from the cooling system. In a preferred embodiment, the cooling system consists of a flattened heat pipe, with a first side operating as the evaporator and a second side operating as the condenser.

International Classification:

F25D 2312

US Classification:

622592

Abstract:

A two-phase cooling system for a portable computer which in one embodiment consists of an evaporator which is positioned within the base of the computer and a condenser which is positioned within or attached to the lid of the computer. The evaporator and the condenser are connected by flexible tubing. The tubing may run externally from the lid to the base or it may extend through one or more of the hinges that connect the base and the lid. In an alternative embodiment, both the evaporator and the condenser of the two-phase system are incorporated into either the base or the lid of the computer.
