Definitions

  • the finless part of the heat exchanger finned tube may differ in length with the type of heat exchanger, and production of finned tubes having finless parts of varying lengths necessitates preparation of restraining dies specifically for the respective finless parts of different lengths to result in increases in cost.
  • the tube to be enlarged can be prevented from rupturing merely by varying the number of tube clamp lower plates to be arranged in the fin setting clearances of the fin setting jig and the number of upper plates to be arranged on the lower plates even when the heat exchanger finned tube tobe produced has a finless part of altered length. Accordingly upper and lower plates need only to be prepared in an increased number. This results in a lower cost than when various metal members must be prepared for specific use.
  • FIG. 1 shows a finned tube for use in heat exchangers
  • FIGS. 4 to 8 show an apparatus and a process for producing the finned tube
  • FIG. 9 shows a process for fabricating a heat exchanger with the use of the finned tube.
  • FIG. 10 shows the overall construction of the heat exchanger fabricated using the finned tube.
  • a finned tube 10 for use in heat exchangers comprises a fin fixing hairpin tube 11 made of aluminum and comprising a tube having no weld seam, such as an extruded tube, and a plurality of fin groups 12 arranged on two straight tube portions Ila of the tube 11 longitudinallythereof at a spacing.
  • the straight tubeportions Ila each have a finless part 13 between each pair of adjacent fin groups 12 thereon.
  • the fin group 12 comprises a plurality of parallel aluminum plate fins 14 extending across and fixed to the two straight tube portions Ila of the fin fixing tube 11.
  • FIG. 10 shows a heat exchanger 1 thus fabricated for use as an evaporator in refrigerators or refrigerated showcases .
  • the straight tube portions Ila are bent in the same direction at the finless parts 13 which are located in the same position with respect to the longitudinal direction of the straight tube portions Ila so that a straight line through the lengthwise centers of the parts 13 will be the center of the curvature, and each pair of finless parts 13 adjacent to each other longitudinally of the straight tube portions Ila are bent in different directions, whereby the tube 11 is bent zigzag in its entirety.
