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.
