Abstract

836,922. Making heat exchanger tubes; soldering and brazing. CLAYTON DEWANDRE CO. Ltd. March 27, 1958 [May 24, 1957], No. 16590/57. Classes 83 (2) and 83 (4). [Also in Group XIII] In making a heat exchanger tube, a wire coil 2 is helically wound around the tube 1, a binding wire 3 and a bonding wire 4 of solder or brazing metal are provided inside the coil and the assembly is passed through an induction coil 5 to melt the solder &c., the bonding wire screening the binding wire from the induction coil. The binding wire 3 and the bonding wire 4 are of flattened section with the bonding wire of a width at least equal to and preferably greater than that of the binding wire. In the induction coil the binding wire is screened so that its temperature rises approximately only at the rate of the temperature of the tube wall. A helical groove 6 is provided in the tube to locate the coil 2, an additional solder wire 7 is wound in the space between the turns of the coil 2 and heating may take place in an inert or reducing atmosphere. The binding wire may be of other section.
