Abstract
Abstract A cooling system for cooling computer components generating thermal energy. The cooling system includes a high efficiency heat exchanger attached to the heat producing component and an evaporator. The heat exchanger comprises a hollow body formed of a thermally conductive material having a coolant inlet and a coolant outlet. A periodically lanced metal fin is located within the hollow body and is oriented between the inlet and outlet to provide maximum contact of the coolant along the surface area of the metal fin. An evaporator is attached to the inlet of the heat exchanger to pre-cool the air flow delivered to the heat exchanger and thus the heat generating component.
