  • Another object of the present invention is to afford a novel method of making a heat transfer element.
  • Another object of the present invention is to afford a novel heat transfer element of the spined type.
  • Heat exchangers embodying outwardly projecting fins, wherein the fins are progressively more closely spaced from one side to the opposite side thereof, have been heretofore known in the art.
  • heat exchangers heretofore known which embodied such construction, have been of the plate-fin type, wherein laterally spaced, elongated passes in the form of tubular members are mounted on or in fin plates, such as, for example, heat exchangers of the type disclosed in US. Pat. No. 3,114,963 issued to R. W. Kritzer on Dec. 24, 1963.
  • Such heat exchangers are often used as evaporators in refrigeration or airconditioning systems, and the like, wherein air flows across the heat exchanger between the fins.
  • An object of the present invention is to afford a novel heat transfer element embodying elongated passes disposed in side-by-side relation to each other, and fins projecting outwardly from the passes transversely to the length of the passes, with'the fins being spaced progressively closer to each other from one side to the opposite side of the heat transfer element transversely to the length of the passes and to the direction of projection of the aforementioned fins.
  • An object ancillary to the foregoing is to afford a novel heat transfer element of the aforementioned type wherein the fins are formed integrally with the body portion of the passes.
  • Another object of the present invention is to afford a novel heat transfer element, embodying an elongated tubular member bent into a serpentine pattern, with fins spaced therealong in a novel and expeditious manner whereby the spacing of the fins on the return bends and passes of the heat transfer element is progressively closer from one end of the tubular member to the other.
  • Another object of the present invention is to afford a novel heat transfer element which is practical and efficient in operation, and which may be readily and economically produced commercially.
  • FIG. 1 is a fragmentary, perspective view of an end of a tubular member illustrating the preferred manner in which integral fins may be formed thereon in accordance with the principles of the present invention
  • FIG. 2 is a fragmentary, side elevational view of a tubular member, illustrating the programmed spacing of fins therealong in accordance with the principles of the preferred embodiment of the present invention.
  • a tubular heat exchanger or heat transfer element 1 is shown in the drawings to illustrate the presently preferred embodiment of the present invention.
  • the heat exchanger 1 embodies an elongated tubular member 2 bent into a serpentine pattern which affords a plurality of laterally spaced, substantially parallel passes 3, interconnected by return bends 4, with fins 5 projecting outwardly from the tubular member 2 transversely to the serpentine pattern of the passes 3 and the return bends 4, FIG. 3.
  • the fins 5 are progressively spaced closer together from one end A to the other end B of the tubular member 2. As somewhat diagrammatically illustrated in FIG. 3, the progressively closer spacing of the fins 5 is by areas, with the fins in each respective area being uniformally or substantially uniformally spaced.
  • the heat exchanger l shown in FIG. 3, embodies six parallel passes 3, with three such areas of fin spacing, the first area embodying the pair 7 of passes 3 disposed most closely adjacent to the end A of the tubular member 2; the next area embodying the central pair 8 of passes 3; and the other area embodying the pair 9 of passes 3 disposed most closely adjacent to the end B of the tubular member 2.
  • the spacing of the fins 3 on the various areas may be any desired spacing, such as, for example, the fins 5 on the pair 7 of passes 3 being spaced two fins per inch; the fins 5 on the pair 8 of passes 3 being spaced four fins per inch; and the fins 5 on the pair 9 of passes 3 being spaced six fins per inch;
  • the showing of the heat exchanger 1 in FIG. 3 as embodying six parallel passes, and the aforementioned progressively closer spacing of two, four and six fins per inch is merely by way of illustration and not by way of limitation, and heat exchangers embodying a greater or lesser number of passes, and a different programming of fin spacing may be used without departing from the purview of the present invention.
  • an elongated, substantially straight tubular member 2a is first formed.
  • the tubular member 2a is preferably rectangular in transverse cross section, and embodies two substantially parallel, wider opposite sidewalls l3 and 14 and two oppositely disposed, substantially parallel narrower sidewalls and 16, FIG. 1.
  • the tubular member 20, thus formed also embodies two elongated ribs 17 and 18 projecting outwardly from and extending in parallel relation to each other longitudinally of each of the sidewalls l5 and 16.
  • the fins 5 may be formed thereon by successively, from one end portion C toward the other end portion D thereof, cutting or gouging the fins 5 from the respective pairs of ribs 17 and 18 and the underlying portions of the sidewalls 15 and 16 in the manner disclosed in U.S. Pat. No. 3,692,105 issued to Joseph M. OConnor on Sept. 19, 1972.
  • the fins -5 are formed on each of the sidewalls 15 and 16 by means of a suitable cutting tool which first cuts along lengthwise of each respective rib l7 and 18 on each sidewall 15 and 16 to form spines 19 and 20, respectively, FIG. 1.
  • the cutting tool continues to cut along lengthwise of the respective sidewalls l5 and 16 to thereby cut the portion thereof underlying the respective ribs 17 and 18 thereon to form a base 21 for each fin 5, the base 21 preferably extending across the entire width of the respective sidewall 15 or 16, and the spines l9 and 20 projecting outwardly from opposite ends of the outer longitudinal edge of each base 21 in parallel spaced relation to each other, FIG. 1.
  • the fin 5 which has been cut or gouged from the sidewall 15 or 16 is then bent outwardly preferably to a position of approximately perpendicular relationship to the plane of the respective sidewall 15 or 16 on which it is formed.
  • the fins 5 are initially formed with enlarged portions, such as the portions 22 shown in FIGS. 1 and 2, the cutting operation causes the fins 5 to compress longitudinally so that, as a practical matter, the enlarged portions 22 substantially disappear on fins of usual thickness, to thereby afford a relatively smooth-sided appearance for the outer ends of the fins 5.
  • the tubular member 2a may be cut off to the desired length, such as, for example, the length of the tubular member 2 embodied in the heat exchanger 1 shown in FIG. 3.
  • the spacing thereof is programmed so as to afford the adjacent areas of progressively more closely spaced fins, with the fins of each particular area preferably being equally spaced. This may be accomplished in any desirable manner, such as, for example, by varying the rate of feed of the tubular member 2a through the cutting machine relative to the speed of reciprocation of the cutting tools.
  • the bending of the tubular member 2 preferably is programmed so as to dispose the pair 7 of passes 3 in the area 23, the pair 8 of passes 3 in the area 24 and the pair 9 of passes 3 in the area 25.
  • the changeover from one area to another is made at the midpoint of one of the return bends 4.
  • the tubular member 2 In the bending of the tubular member 2, it preferably is bent into a serpentine pattern, as shown in FIG. 3, wherein the passes 3 are disposed in parallel relation to each other, with the passes 3 and the return bends 4 being disposed in substantially uniplanar relation, and with the fins 5 projecting outwardly from both sides of the tubular member 2 transversely to the plane extending between the sides 11 and l2'of the heat exchanger 1.
  • fins 5 are shown projecting outwardly from two opposite sides of the tubular member 2 merely by way of illustration of the preferred form of the present invention, and not by way of limitation, and that, if desired, the fins 5 may be formed only on one of the sidewalls 15 or 16 of the tubular member 2a without departing from the purview of the broader aspects of the present invention.
  • the present invention affords a novel method of making a heat exchanger of the fin type, wherein the spacing of the fins is programmed to afford progressively closer spacing from one side to the opposite side of the heat exchanger.
  • a heat transfer element comprising a. a tubular member having an elongated wall, having two pairs of oppositely disposed longitudinally extending sides, b. said tubular member being bent back and forth in a serpentine pattern to afford 1. a plurality of elongated passes laterally spaced from each other from one side to the opposite side of said pattern, and
  • said fins on respective ones of said passes being spaced progressively closer to each other longitudinally of said tubular member from said one side to said opposite side of said pattern.
  • tubular member in which a. said tubular member is substantially rectangular in transverse cross-section and has 1. two substantially parallel, oppositely disposed sidewalls forming said sides in said one pair, and
  • said two other sidewalls are narrower in width than said first mentioned two sidewalls.
  • said fins comprise spines spaced from each other across the width of said two other sidewalls.
  • said fins comprise l. elongated base portions a. extending across the width of said two other sidewalls, and b. having an outer longitudinal edge, and 2. a plurality of spines a. spaced along said longitudinal edges, and b. projecting outwardly therefrom.
  • a method of making a heat transfer element comprising a. forming an elongated tubular member having two pairs of oppositely disposed longitudinally extending sides,
