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 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 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.

The invention claimed is: 1. 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. 2. The housing as claimed in claim 1, wherein the heat exchanger comprises: an inlet manifold and an outlet manifold, between which two manifolds the capillaries extend so that medium can flow therethrough. 3. The housing as claimed in claim 1, wherein the wires contact adjacent capillaries alternately on the one side and on the other side, wherein adjacent wires or groups of wires contact the other sides of the capillaries relative to nearby wires or groups of wires, such that the wires or groups of wires are mutually interwoven. 4. The housing as claimed in claim 1, wherein two groups of wires extend in two main planes in mutually parallel relation, wherein the wires of each group contact the same side of the capillaries. 5. The housing as claimed in claim 1, wherein the inlet manifold has at least one interruption or plug, the outlet manifold has at least one interruption or plug placed offset relative thereto such that the medium admitted through the inlet of the inlet manifold is guided successively through a first inlet manifold, the group of capillaries connecting thereto, a first intermediate manifold, a second group of capillaries and so forth, and finally the outlet manifold such that the medium moves in the one direction in zigzag manner in the group of capillaries and moves in opposite direction in the following group of capillaries. 6. The housing as claimed in claim 1, wherein the capillaries are formed from one capillary tube modeled into a zigzag shape, wherein each end of each capillary is connected via a U-shaped curved part to the end of a nearby capillary, wherein the end zones of the capillary tube are connected to respective tubes acting as manifolds. 7. The housing as claimed in claim 6, wherein the U-shaped curved parts of both sides of the mat are in register and coupled mechanically to each other by means of a strengthening profile with a low heat conduction. 8. The housing as claimed in claim 2, wherein each manifold is a tube in which a row of perforations is arranged, in which perforations the ends of the capillaries are sealingly inserted. 9. The housing as claimed in claim 6, wherein the tubes consist of metal, for instance tin-plated copper, and the capillaries are connected to each tube by soft-soldering at a temperature of about 300° C. or hard-soldering at a temperature of 500° C.-800° C. 10. The housing as claimed in claim 6, wherein each capillary consists of tin-plated copper and the ends of each capillary are stripped of tin prior to the hard-soldering, for instance by means of an anodic treatment in an aqueous solution of NaOH or HCl. 11. The housing as claimed in claim 1, wherein the housing includes at least two manifolds and wherein each manifold is a tube of thermoplastic material, for instance PP, PE, ABS or EPDM, in which tube a cut is made in longitudinal direction on one side, whereafter the ends of the capillaries are placed in the cut and the material of the tube is then melted at that position by local heating such that the capillaries are connected substantially sealingly to the tube. 12. The housing as claimed in claim 1, wherein the capillaries each have an outer diameter of about 1.8 mm±30% and a wall thickness of about 0.4 mm±40%. 13. The housing as claimed in claim 3, wherein the centre-to-centre distance of the capillaries amounts to about 10 mm±40%. 14. The housing as claimed in claim 4, wherein the centre-to-centre distance of the capillaries lies in the range of about 4-16 mm. 15. The housing as claimed in claim 1, wherein the wires have a diameter of 0.12 mm±50%. 16. The housing as claimed in claim 11, wherein the main flow direction of the medium is an effective counter-flow with respect to the direction of the air. 17. The housing as claimed in claim 1, wherein the heat exchanger comprises a number of heat exchanger mats held by spacers in mutually parallel and equidistant relation. 18. The housing as claimed in claim 17, wherein the spacers are mutually abutting inlet manifolds and outlet manifolds. 19.

The housing as claimed in claim 1, wherein the medium is one of the group comprising: groundwater, water drawn from the mains water supply, sewage water, water from an underground river, surface water and water from an aquifer. 22. The housing as claimed in claim 21, wherein the medium flows directly through the heat exchanger. 23. The housing as claimed in claim 21, comprising a second heat exchanger of the liquid-liquid type which is connected in one shared medium circuit to said first heat exchanger, through which circuit flows a heat transport medium, for instance a liquid such as water, a liquid-vapour mixture and/or a gas such as air, the surface of which second heat exchanger is in direct contact, on the side remote from said circuit, with a medium from said group. 24. The housing as claimed in claim 21, wherein the medium is transported from a supply of this medium to the medium inlet of the heat exchanger, is transported therethrough and transported out of the medium outlet, wherein the medium inlet is in direct contact with a supply of medium from said group, and the medium outlet is in direct contact with either the same or another supply of medium from said group, and wherein an additional cooling device, for instance a cooling tower, is arranged between the medium outlet and the medium inlet.
