Abstract
A method for producing a heat exchanger for a motor vehicle, wherein the heat exchanger has reservoirs and a bundle of flow-through fluid conduits for guiding the flow between the reservoirs. The conduits are produced together as a bundle. A heat exchanger for a motor vehicle, especially a micro-channel cooler, can be produced by this method.
Claims9
A method for producing a heat exchanger for a motor vehicle comprising:
- providing at least two reservoirs, and
- forming flow-through, individual, separate fluid conduits for guiding fluid flow between the at least two reservoirs, wherein the conduits are formed by an extrusion process that forms the conduits as a bundle of conduits, wherein the bundle of conduits includes the conduits spaced apart in parallel rows allowing air flow between the parallel rows of the conduits, and wherein each of the conduits of the bundle of conduits comprises a separate hollow tube.
A method for producing a heat exchanger for a motor vehicle comprising:
- providing at least two reservoirs, and
- forming flow-through, individual, separate fluid conduits for guiding fluid flow between the at least two reservoirs, wherein the conduits are formed by an injection molding process that forms the conduits as a bundle of conduits, wherein the bundle of conduits includes the conduits spaced apart in parallel rows allowing air flow between the parallel rows of the conduits, and wherein during the injection molding process support plates are produced together with the conduits using the injection molding process, and the support plates are connected to the conduits.
A method for producing a heat exchanger for a motor vehicle comprising:
- providing at least two reservoirs, and
- forming flow-through, individual, separate fluid conduits for guiding fluid flow between the at least two reservoirs, wherein the conduits are formed by a hydroforming process that forms the conduits as a bundle of conduits, wherein the bundle of conduits includes the conduits spaced apart in parallel rows allowing air flow between the parallel rows of the conduits, and wherein during the hydroforming process the at least two reservoirs are produced together with the conduits using the injection molding process, and the at least two reservoirs are connected to the conduits.
