HEAT EXCHANGING ELEMENT AND METHOD FOR THE MANUFACTURE THEREOF

摘要

One embodiment of a heat-exchanger element includes a metal layer (1) and at least one metal conduit (2) which lies against and is fused together with the metal layer and which extends between two mutually opposing outer edges of the element so that the metal layer will form heat-transporting flanges on both sides of the conduit. The conduit is fused with the metal layer so that the conduit will have a free-laid surface which faces away from the metal layer. Another embodiment of the element includes two metal layers and at least one metal conduit which is placed between and lies against and is fused with the metal layers and extends between two mutually opposing edges of the element so that the metal layers form heat-transporting flanges on both sides of the conduit. At least one metal layer has a groove in which part of the conduit is inserted. The invention also relates to methods of manufacturing such elements.
