Abstract

692,885. Making heat-exchangers. BROWN FINTUBE CO. Dec. 12, 1950 [Dec. 28, 1949], No. 30337/50. Classes 83 (ii) and 83 (iv). [Also in Group XIII] A method of making a heatexchanger or heat-exchanger conduit comprises winding a heatexchanger packing around the outer surface of a metallic tube, inserting the tube with the packing thereon into an outer tube with the outer surfaces of the packing engaging the inner surface of the outer tube and then deforming one of said tubes to bring the packing into firm engagement with the tubes. A heat exchanger according to the invention comprises concentric copper tubes 10 ... 13 forming annular spaces 14 ... 16, the ends of which are closed by plates 18 ... 20 brazed or soldered to the tubes. Pipes 22 ... 24 communicate with the annular spaces. Extended heat transfer surfaces are provided in the annular spaces by a packing 25 which is formed of copper wire wound into a rectangular coil, the longer sides of the rectangle providing pin-like elements 26 and the shorter sides 31, 32 engaging the inner and outer tubes. The wire coil, which is tinned with solder, is wound around the inner tube, e.g. tube 11, in closely spaced convolutions, the end of the coil being soldered to the tube. The inner tube together with the packing 25 is then inserted into the outer tube (Fig. 6). In order to bring the shorter sides 31, 32 of the packing 25 firmly into engagement with the tinned walls of the inner and outer tubes the inner tube 11 is expanded by a mandrel 36 drawn through the tube by a rod 37 (Fig. 7). The assembly is then heated in a furnace to effect the soldering. The packing may be formed of a coil 40 wound in one direction and a coil 41 wound in the opposite direction (Fig. 9). The coils are relatively short and are disposed circumferentially about the tube 11a in single turns, alternate turns being of opposite hand and the turns intermeshed to provide close longitudinal spacing of the pinlike elements 26a formed by the coils.
