Definitions

  • This invention relates generally to heat exchange units and more specifically to a multi-pass heat exchanger which employs serpentined tubes for at least one pass with the U-bends of said serpentined heat exchange tubes being internally located and having fin members in operative relationship therewith.
  • Another object of the invention is to provide a brazed heat exchanger with internally finned heat exchange tubes which increase the efiiciency of the heat exchanger and will withstand high operating pressures.
  • a still further object of the invention is to provide an internally tubed brazed heat exchanger in which a continuous corrugated fin is provide with recesses to accommodate the tube member.
  • a fifth object of the invention is to provide a heat exchanger with serpentined heat exchange tubes which lie in recesses formed in a continuous corrugated fin member.
  • Another object of the invention is to provide a brazed aluminum heat exchanger in which a continuous corrugated fin element, with tube receiving recesses formed therein is employed to accommodate a serpentined heat exchange tube thereby forming a heat exchanger which is readily manufactured, efiicient in operation, and will withstand high operating pressures.
  • FIGURE 1 is a perspective view of a typical heat exchanger with a portion broken out to show the general features of my invention
  • FIGURE 2 is a top view of one continuous corrugated fin member with a serpentined heat exchange tube therein;
  • FIGURE 3 is a side view of FIGURE 2;
  • FIGURE 4 is an end view showing two continuous corrugated fin members spaced one atop the other with a serpentined heat exchange tube therebetween;
  • FIGURE 5 is a perspective view of a portion of the tube receiving recesses formed in the fin member to receive the serpentined tube member;
  • FIGURES 6 and 7 are views similar to FIGURE 2 showing the location and shape of the parting sheets as applied to heat exchangers with diiferent entering and exiting tube members.
  • FIGURE 8 is a top view of a modification of the heat exchanger shown in FIGURES 1-7;
  • FIGURE 9 is an end view of the heat exchanger of FIGURE 8.
  • FIGURE 10 is a side View of the heat exchanger shown in FIGURE 8.
  • FIGURE 1 a typical heat exchanger 10 is shown incorporating my new and novel arrangement.
  • the invention is shown as applied to a two pass heat exchanger but obviously heat exchangers of many passes and header arrangements can be employed within the scope of the invention.
  • a cooling fluid enters header 12 through inlet 13 and passes through serpentined heat exchange tube 14 and is collected in header 16 and discharged through outlet 17.
  • Hot gas preferably, enters header 18 through inlet 19 and passes counterflow to the cooling fluid through plate type corrugated heat exchange fins 20 to outlet header 22 from whence it is discharged through outlet 23.
  • Corrugated fin members 20 of the plate type and serpentined tubes 14 are constructed from aluminum, preferably, because aluminum provides a non-corrosive and light weight heat exchanger. Obviously though, stainless steel fin members or tubes could be used. If higher tensile strength is necessary aluminum alloys also could be employed. Other materials and combinations thereof can be employed, if desired.
  • heat exchanger 10 is constructed of a series of heat exchange sections 24 brazed or welded together.
  • Parting sheets 26 are employed between each heat exchange section 24 to form a unitary structure. These parting sheets 26 may be brazed or welded to the respective heat exchange section.
  • Each heat exchange section 24 basically consists of two corrugated fin members 20, a serpentined heat exchange tube 14 between the fins 2t), and a parting sheet 28 between the fins 2t? brazed or welded to the tubes 14 and the fin members 20.
  • Channel sections 30 and block oil. bars 31 are provided to prevent leakage of gas to the outside and provide structural strength to the heat exchanger.
  • Each fin member 29 has at least three sections, namely 32, 34, and 36. Additional sections 34 may be employed depending on the width or length of heat exchanger desired. The particular length and width of sections 32 and 36 are not considered part of the invention.
  • Each fin member section 34 has a plurality of recesses 37 formed therein to accommodate half the diameter of the straight portion 38 of the serpentined heat exchange tube 14. These recesses are formed in the manner shown and described in my Patent No. 2,820,617, filed November 7, 1955, and issued January 21, 1958.
  • Fin member sections 32 and 36 are formed with U-bend recesses 40 to accommodate the U-bend sections 42 of serpentined heat exchange tube 14.
  • the portion of the sections 32 and 36 where the serpentined tubes 14 are headered are formed with recesses 44 like those of fin member section 34.
  • a parting sheet 26 is first put down. Then a corrugated fin member consisting of sections 32, 34, and 36 is laid on the parting sheet with the recesses facing upwardly.
  • a serpentined heat exchange tube 14 is placed on the fin member 20 with the straight portions 38 of serpentined tube in the recesses 37 and 44 and the U-bencls in the recesses 40.
  • Parting sheets 46 and 48 or Stl and 52 are then placed on the fin members 20 with the projections 54 extending between the U-portion of the serpentined tube.
  • a second fin member 20 is then placed upon the tube 14 and the first fin member 20, so that the fin portions of the first fin member and the second fin member surround and engage tube 14.
  • a second parting sheet 26 is placed on top of the second fin member 20 and channel sections 30 are placed adjacent the end of the corrugated fin member 20. The whole assembly is then temporarily held together by any suitable means such as clamping and is brazed or welded by any suitable process.
  • the heat exchanger 10 will be built up to the appropriate length, width, and depth and brazed as unit instead of individual brazing of heat exchange sections 24 and then the appropriate headers such as 12, 16, 18, and 22 are brazed on.
  • FIGURES 6 and 3 7 show two forms of parting sheets which are used with my heat exchanger depending on whether the serpentined tubes 14 enter and exit on the same side of the heat exchanger or on opposite sides of the heat exchanger.
  • FIGURE 6 shows the parting sheets 46 and 48 which are used between fin members 29 when the serpentined tube 14 enters and exits on the same side of the heat exchanger 10.
  • FIGURE 7 shows the parting sheets 50 and 52 which are employed when the serpentined tubes 14 enter one side of the heat exchanger and exit from the other side.
  • the heat exchanger 10 is shown composed of a series of corrugated fins 2t stacked one upon the other with serpentined heat exchange tubes 14 disposed between each corrugated fin member.
  • the fin member as in the embodiment of FIGURES 17, has at least three sections 32, 34, and 36 with recesses 37, 4t), and 44 therein to accommodate the serpentined tubes 14.
  • the recesses are so formed so as to surround and engage the tube 14.
  • Parting sheets 28 like those of FIGURES 6 and 7 are employed between the fin members and parting sheets 26 are employed on the top and bottom of the heat exchange section.
  • FIGURE 8 the section 32 of the top heat exchange section 20 has been removed to show the offset relationship of the serpentined heat exchange tubes.
  • the heat exchange tubes between adjacent fin members 2t? are offset in relation to one another. This is necessary due to manufacturing reasons since the forming of recesses on both sides of the heat exchange members with one recess on top of the other would weaken the fin member and be very diificult to form.
  • a heat exchanger comprising: a first inlet header and a first outlet header, a plurality of pairs of corrugated plate type fin members extending between said first inlet header and said first outlet header and forming a passage for a first heat exchange fluid, said fin members of each pair being superimposed and co-extensive with the other fin member of the pair, means forming a plurality of recesses in said fin members, said recesses being located to form a passage between said fin members in each pair to accommodate a serpentined heat exchange tube, a serpentined heat exchange tube located in said recesses with the U-bends of said heat exchange tube being confined within said fin members, and means communicating with said heat exchange tube to provide for passage heat exchange fluid into and out of said heat exchange tube.
