Definitions

  • This invention relates essentially to heat exchangers and notably to heat exchangers of the type comprising a nest of parallel longitudinally aligned Itubes adapted Ifor eecting heat transfer ibetween Ia heat exchanging medium passing through the interior of said tubes and an external iluid tilowing in a generally longitudinal direction through said nest along the external surf-aces of said tubes.
  • the heat exchanger according to lthis invention comprises a nest of longitudinally extending parallel tubes .adapted for the passage therethrough of the heat exchange medium to effect heat ytransfer between said medium and an external -uid circulating in a -generally longitudinal direction through said nest alon-g the external surfaces of said tubes.
  • the outer surfaces of said tubes are peripherally grooved to Ifor-m on said surfaces integral tn means extending substantially transversely of said tubes.
  • the tubes are arranged in an yarray of rows and columns such that ⁇ the axes of said tubes respectively detine a regular triangular lmesh pattern in which a tube in :any one row forms a regular triangle with -two adjacent tubes, -at least one ⁇ of which lies in an adjacent row.
  • each plain tube is surrounded by tubes with strip -means thereon and in each row there is alternately disposed a plain tube .and Itwo tubes Vwith strip means thereon.
  • the strip means are helically wound in opposite directions on adjacent tubes, each strip means contacting the outer surface of an ⁇ adjacent tube such .that each tube with strip means thereon is disposed between a bare tube and a tube with strip means thereon which is Wound in an opposite direction, while each bare tube is disposed between two tubes with strip means thereon which are wound in opposite directions.
  • FIGURE 1 illustrates diagrammatically in cross section one portion of a nest of heat exchange tubes according to the invention
  • FIGURE 2 is a diagramrnatical side elevational view showing one row of tubes as taken along arrows II-II in FIG. 1,
  • FIGURE 3 is a detail view, with parts shown in axial section, of one end .of the nest illustrated in FIGS. 1 and 2, and
  • FIGURE 4 is a cross-section taken along line lV-IV of FIG. 3.
  • a heat exchanger comprises a triangular mesh nest.
  • the nest is considered to be comprised of bare tubes lil arranged in an .array of rows and columns such that the axes of the tubes 10 respectively dene a regular triangular mesh pattern in which a tube in Iany row for-ms a regular triangle with two adjacent tubes, at least one of which lies in an adjacent row.
  • a iluid medium circulates externally of the tubes in a generally longitudinal direction, for example -from top :to bot-tom, and contacts the walls of the tubes which are formed with relatively shall-0W peripheral grooves extending transversely.
  • a rotary motion is imparted to the circulating duid in each stream formed between adjacent tubes 1@ by interposing between the tubes further tubes similar to those of tubes 10 but having wound and secured thereon a fiat, spiral-forming strip
  • a dat forming strip 12 there is interposed between adjacent tubes 10 tube 11 similar to tubes 1t) but having wound and secured thereon, for example by spot welding, a dat forming strip 12.
  • This strip ⁇ 12 extends preferably normally to the surface of the tube on ywhich it is wound and secured. From FIGURE 1, it will be seen that the width of strip 12 is such that its outer edge engages the wall of the tubes 10.
  • any one of the tubes shown in FIG. ⁇ 1 pertains to three angularly equidistant rows of tubes, such as the row along line II--II shown in elevational view in FIG. l2.
  • a bare tube such as -tube ,10
  • tubes 11-17, ⁇ 14, 19 or ⁇ 1li-18 provided :with iin-like strip means wound helically thereon according to Iopposite pitches respectively.
  • tube 11 is disposed between a bare tube 10 and a tube provided with opposite pitch helical strip means, such as tubes 14 or '18, according .to the row being considered.
  • the heat exchanger structure as shown could be fur- .ther described by yconsidering tha-t any one of the tubes shown in lFIG. 1 is surrounded by six adjacent tubes, and that these seven tubes constitute a unit mesh of ,the heat exchanger nest.
  • the central tube is surrounded by six tubes in a particular arrangement.
  • the bare tube 10 located centrally of FIG. l is surrounded by -tubes 11, 16 and v19, provided with lefthand wound helical strip means 12 and by tubes .14, 17 and .18 provided .with right-hand wound fhelical strip means 15, Whereas each tube with a strip means thereon is surrounded by alternating bare tubes and tubes with strip means thereon in which the latter are all wound in opposite direction with respect to the strip means on the central tube.
  • FIGURES 3 and 4 illustrate the manner in which Ithe seven tubes 10, 11, 14 land 16-19 constituting a central hexagonal mesh in FIG. l are interconnected at their upper and/or lower ends in the case of a vertical heat exchanger, the tube end portions being left plain after the formation of the ns, splines, ribs, grooves or low-pitch threads therein.
  • the central 4tube -10 has six circular ports formed Itherein, these ports being disposed as shown by ⁇ diarnetrally opposite pairs in three superposed planes intersecting the tube axis at 60-degree intervals, the necks of the bent ends of tubes
  • each tube has tted therein a cylindrical core such as a, Illa, s17a, etc. in a cylindrical or tubular core such ⁇ as 11a, 10a, 17a closed at top and bottom by a streamlined, water-tight or nearly water-tight tip portion as shown at 11b, 1Gb and 17b in FdG. 3.
  • a cylindrical core such as a, Illa, s17a, etc.
  • a cylindrical or tubular core such ⁇ as 11a, 10a, 17a closed at top and bottom by a streamlined, water-tight or nearly water-tight tip portion as shown at 11b, 1Gb and 17b in FdG. 3.
  • the cross-sectional area of the annular space formed between the tubes 1/1 and 11a, 10 and 10a, 17 and 17a corresponds substantially to that of the tapered and -bent end portions of these tubes which connect the latter to the central tube 10.
  • the six mesh-forming tubes can be connected to the central tube by means of slightly tapered end portions without restricting the cross-sectional area available for the passage of the inner tluid.
  • This arrangement is particularly valuable in the case of nuclear reactors wherein the number of welds should be as small as possible.
  • FIGURE 4 illustra-tes by Way ⁇ of example this hexagonal distribution of the six tubes 11, 14, 161, 17, 118 and 19 about the central tube 10.1
  • this invention is also concerned with a tubular nest having a square pattern.
  • a heat exchanger comprising a plurality of longitudinally extending parallel tubes adapted for the passage therethrough of a heat exchange medium, said tubes being arranged in an array of rows and columns such that the axes of said tubes in any lone row forms a regular triangle with two adjacent tubes at least one of which lies -in an adjacent row, said tubes being adapted for the passage along .the external surfaces thereof of a second heat exchange medium, said tubes having peripheral transverse grooves in the .outer surfaces thereof, said grooves extending substantially perpendicular to the longitudinal direction of the tubes, helically wound strip means on the outer surface of selected tubes, the remainder being plain, said tubes with the strip means being selected such that each plain tube is surrounded by tubes with strip means thereon and in each row there are alternately disposed a plain tube and two tubes with strip means thereon, said strip means being helically Wound in opposite directions on adjacent tubes each strip means contacting the outer surface of an adjacent tube, such that each tube with strip means thereon is disposed between a plain tube and a tube
