Patent ID: 7830658

Claim:
A housing for heat-generating electronic equipment, said housing being provided with cooling means for cooling the air present in the housing and for discharging heat coming from the equipment, the housing is closed at least during operation; the air circulates in the housing during operation by means of fan means; and the cooling means comprise a heat exchanger with: an air inlet and an air outlet for exchanging heat between passing air and a liquid-containing medium, such as a liquid such as water, or a liquid-vapour mixture, and a gas such as air, which heat exchanger also comprises a medium inlet and a medium outlet and at least one substantially flat heat exchanger mat, which mat comprises: a number of capillaries of heat-conducting material, for instance tin-plated copper, disposed in mutually parallel and mutually equidistant relation; and a number of wires of heat-conducting material, for instance tin-plated copper which are attached in heat-conducting, preferably metallic contact to the capillaries, extend in mutually equidistant relation in transverse direction relative thereto and have a mutual distance in the order of magnitude of the diameter of the wires; wherein under the influence of drive means air can flow along the wires for heat exchange between this air and the medium flowing through the capillaries via the walls of the capillaries and the wires, wherein the heat exchanger is embodied such that the air flows along the or each mat and at least a substantial part of the air is prevented from flowing through the mat; and wherein the air flows in longitudinal direction of the wires.
