A heat exchanger for exchanging heat between a liquid-containing medium and a gas comprises a medium inlet and a medium outlet and a flat heat exchanger mat, wherein the mat comprises a number of parallel, equidistant capillaries of heat-conducting material and wires of heat-conducting material which are attached in heat-conducting contact to the capillaries, extend in transverse direction relative thereto and have a mutual distance in the order of magnitude of the diameter of the wires, wherein gas can flow along the wires for heat exchange between this gas and the medium flowing through the capillaries, and wherein the gas flows along the mat and at least a substantial part of the gas is prevented from flowing through the mat, and the gas flows in longitudinal direction of the wires.
The invention relates to a ventilation system for exchanging the air in a room with outside air, which system comprises: A fine wire heat exchanger having a first channel and a second channel, which channels are in heat-exchanging contact with each other, and wherein the first channel has an inlet connected to outside air and an outlet connected to the air in the room, and wherein the second channel has an inlet connected to the air in the room and an outlet connected to the outside air; balancing means for balancing the flow in both channels, such that the heat transfer is maximized. The invention also relates to a combination of a façade, a room on the inside of and adjacent to the façade and a ventilation system, wherein the inlet of the first channel of the system is connected to outside air on the outside of the façade and the outlet is connected to the air in the room, and wherein the inlet of the second channel is connected to the air in the room and the outlet is connected to the outside air.

A housing for electronic equipment comprises a heat exchanger for exchanging heat between a liquid- containing medium and a gas. This heat exchanger comprises a medium inlet and a medium outlet and a flat heat exchanger mat. The mat comprises a number of parallel, equidistant capillaries of heat-conducting material and wires of heat-conducting material which ar attached in heat-conducting contact to the capillaries, extend in transverse direction relative thereto and have a mutual distance in the order of magnitude of the diameter of the wires, wherein air can flow along the wires for heat exchange between this air and the medium flowing through the capillaries. The heat exchanger is embodied such that the air flows along the mat and at least a substantial part of the air is prevented from flowing through the mat, and that it is ensured that the air flows along the wires in longitudinal direction of these wires.
