Definitions

  • the tube coil system is fed through and supported Within three radially disposed retaining plates.
  • a plurality of plates are disposed between the retaining plates in supporting relation to the tube coils which pass therethrough. These latter plates are of less radial length than the retaining plates and are secured to only one coil of the tube coils passing therethrough.
  • This invention relates to a tubular heat exchanger. More particularly, this invention relates to a tubular heat exchanger utilizing helically or spirally wound tubes for conveying a working medium.
  • tube coils have been utilized to convey a working medium through an extended path within a heat exchange area.
  • these tube coils have been mounted in various types of radial members for support as well as for the prevention of unequal stresses due to differential thermal expansion.
  • the various tube coils of these known heat exchangers have frequently been subjected to adverse bending or localized buckling between the radial support members, especially, under severe service conditions, such as during operation at very high temperatures e.g. above 500 C., or under conditions providing a high heat transfer rate from the medium flowing over the tube coil to the medium flowing through the tube coil.
  • the invention provides a tubular heat exchanger having a tube coil system consisting of at least one helically or spirally wound tube and at least three retaining plates disposed radially of the tube coil and secured to each other in supporting relation to the tube coil system, for example, as described in US. patent application, Ser. No. 626,453, filed Mar. 28, 1967, with at least one additional plate.
  • This additional plate is disposed to lie approximately in the plane of the tube coil axis so as to receive and secure at least some of the turns of the tube coil.
  • the plate is sized to be of a radial Width which is smaller by at least one radial pipe pitch than the radial width of the tube coil system.
  • FIG. 1 illustrates an axialsection through a tubular heat exchanger according to the invention
  • FIG. 2 illustrates a plan view of the tubular heat exchanger of FIG. 1.
  • the heat exchanger includes a central core 30 within a housing 61 to which three one piece retaining plates 4, 5, 6 are fixed to extend radially outwards in planes containing the axis of the heat exchanger.
  • a plurality, for example, ten, of helical coils 2 of progressively increasing coil diameter are mounted concentrically in the plates 4-6 to form the tubes of the tube coil system of the heat exchanger.
  • the retaining plates 4-6 have holes to receive the coils 2 and the tubes are threaded through the holes by rotating the coils 2 about the common axis to produce a screwing action.
  • the sector-shaped spaces between the retaining plates 4-6 have additional plates 60, for example, a total of fifteen, which are distributed around the circumference of the heat exchanger at diiferent angles with respect to the retaining plates 4-6 to form different sector angles between adjacent plates.
  • Each of these additional plates 60' has holes therein through which the tubes of the coils 2 pass and each is secured to at least one of the coils 2, as by welding.
  • the plates 60 are sized to be of a width smaller than the radial width of the tube coil system by at least one radial pipe pitch and of a length in the axial direction equal to that of the retaining plates 4-6.
  • the plates 60 are located between the core 30 and housing 61 Without being rigidly joined thereto.
  • the tube lengths between two retaining plates can become distorted in the event of large temperature differences between the primary and secondary media and in the event of a high heat transfer rate.
  • the lengths of the tubes between the plates are unequal.
  • the spacing of the plates are selected such that the free tube length between two adjacent plates cannot be excited into resonant oscillation.
  • tube coils 2 of the heat exchanger are constructed in helical form.
  • the tube coils can also be formed spirally or disposed on a conical envelope.
  • the plates 60 are secured to the tube coils in a manner so that the plates 60 cannot move relative to the tube coils extending theret-hrough.
  • resilient rods can be used to join each plate 60 to an adjacent retaining plate 4, 5, 6. Such resilient rods will accommodate the expansion movements of the tube coils due to temperature changes and, therefore, also permit corresponding motion of the plates 60.
  • a heat exchanger comprising at least three retaining plates disposed in fixed spaced apart radial disposition to each other;
  • a tube coil system including at least one wound tube coil having a plurality of coil turns passing through and secured in said retaining plates, said tube coil having an axis disposed in the axial plane of each of said retaining plates;
  • At least one additional plate disposed radially of said tube coil axis, said additional plate receiving at least some of said coil turns of said tube coil in fixed relation and being of a radial width less than the radial width of said tube coil system by at least one radial tube coil pitch.
  • a heat exchanger as set forth in claims 1, 2 or 3 which contains a plurality of said additional plates spaced between said retaining plates to form sectors of unequal angles between each pair of adjacent retaining plates.
