Thereafter, the fins 5 and 6 may be successively formed on each of the sides 7 and 8, respectively, of the wall 3 from one end portion of the tubular member 9, such as the end portion A, toward the other end B thereof, FIG. 2. Each of the fins 5 and 6 may be cut or gouged from the sides 7 and 8, respectively, by means of a suitable cutting tool which cuts along lengthwise of the ribs 10, to the right, as viewed in FIG. 2, to form the surface 11, which terminates at its right end, as viewed in FIG. 2, adjacent to but outwardly of the bases 12 of the ribs 10.
  • each of the fins 5 and 6 After each of the fins 5 and 6 has been cut or gouged from a rib 10 on the tubular SHOWN member 9, it is bent outwardly into a suitably shaped flexure, preferably in the form of a smooth curve, such as, for example, a portion of a circle or a portion of an elipse. If desired, such shaping of the fins 5 and 6 may be performed by the cutting tools.

  • each adjacent pair of rows 13 and 14 of fins 5 and 6 define an elongated passageway 18, which extends transversely across the elongated tubular member 9 for the passage of air, or other suitable working fluid which may surround the heat exchanger 1, across the heat exchanger 1, transversely to the length of the latter.
  • Each of the tubular members 18 in the preferred form of heat exchanger 1, shown in FIGS. 1 and 2 is interrupted at various points in its length, corresponding to the spaces between the adjacent ribs 10, so as to afford passageways 19, FIG. 1, extending longitudinally of the heat exchanger 1 between the fins 5 or 6 formed on respective adjacent pairs of the ribs 10. This, in addition to affording passageways between fins 5 and 6, extending longitudinally of the heat exchanger 1, increases the heat transfer surface of each of the fins 5 and 6.
  • this portion of the tubular stock 9 may be severed from the remainder B-C thereof, FIG. 2, to thereby afford a heat exchanger, such as the heat exchanger 1 shown in solid lines in FIGS. 1 and 2.

  • the construction of the heat exchanger 1 is such that the outwardly facing portions I7 of the surfaces 16 of the fins 5 and 6 may be readily secured to supporting members, such as, for example, plates, or the like, not shown, by suitable means, such as, for example, by a suitable adhesive, such as, an epoxy resin, or by strip soldering, or by brazing, and the like.
  • the flexure of the fins 5 and 6 is in the form of a smooth curve, such as a portion of a circle or of an elipse.
  • the flexure of the fins 5 and 6 is such that the free end portions 15 thereof project downwardly or inwardly toward the center of the tubular member 2, into the aforementioned engagement with the face 16 of the next adjacent fin 5 or 6.
  • the free end portions 15 of the fins 5 and 6 are disposed in abutting engagement with adjacent fins 5 and 6.
