Definitions

  • the invention relates to a heat exchanger with at least one, preferably metallic tube plate and a plurality of arranged in bores of this tube plate tubes made of plastic, preferably PTFE, which are attached to the separation of the two media involved in the heat exchange pressure-tight manner to the tube plate.
  • the plastics used for the production of the heat exchanger tubes which are preferably saturated fluoroplastics, are characterized in addition to a pronounced Creep at elevated temperatures by about ten times the thermal expansion compared to metal. This means that in a bundle of plastic pipes, the relative displacements of the tubes relative to the surrounding metallic walls reach significant values, so that constructively must be taken to compensate for the different dimensions and ensure that it is not due to the large relative movements not jamming and Displacements of the pipes can come opposite the pipe supports and housings.
  • the invention has for its object to provide an inexpensive and repairable detachable and pressure-tight attachment of plastic pipes to flat or curved tube plates, which in particular consist of metal, but can also be made of plastic.
  • each tube is provided for attachment to the tube plate at each end with a flange formed integrally from the tube end, which rests against a respective bore in the tube plate surrounding annular bearing surface and by an elastic Be is held fastening element.
  • the invention results in a simple and inexpensive producible pressure-tight attachment of plastic pipes of heat exchangers to the associated tube plates, which also allows repair or replacement of individual tubes.
  • the at the respective pipe end integrally formed with this flange can be made in a simple manner by deforming the pipe end under the action of heat.
  • the required for this flange annular support surface around the respective hole in the tube plate can be produced in a simple manner by an additional drilling of the tube plate, which can be made in one operation together with the through hole.
  • the elastic fastening element used to fix the tube end to the tube plate is a cheap, commercially available component whose installation is simple and inexpensive.
  • a sealing ring can be arranged between the tube plate and each tube.
  • the fastening element is formed by a plate-spring-like retaining ring, which abuts with its outer edge on the wall provided for generating the support surface for the flange ring and abuts with a part of its end face on the flange.
  • the flange with U-shaped cross-section in the Form a bead around 90 ° to 180 °.
  • the dimensional stability of the flange ring can be increased.
  • a part of a tube plate 1 of a heat exchanger or collector can be seen; this tube plate 1 is provided with through-holes la, in each of which a tube 2 made of art fabric, preferably polytetrafluoroethylene is used.
  • This tube 2 is provided at its end for attachment to the tube plate 1 with a flange ring 2a formed integrally from the tube end. This flange 2a extends in the embodiment of FIG. 1 at right angles to the longitudinal axis of the tube. 2
  • the bore 1a is provided with a bore 1c larger diameter, so that there is the necessary space for the flange 2a.
  • an elastic fastener is used, which reliably presses the flange 2a against the support surface 1b of the tube plate 1.
  • This elastic fastening element is formed in the embodiments by a plate-spring-like retaining ring 3.
  • this retaining ring 3 lies with its outer edge against the wall of the boring 1c designed to produce the bearing surface 1b and with a part of its end face extending from its inner edge on the flange ring 2a of the pipe 2. In this way, a constant pressure is exerted on the flange 2a of the tube 2, which reliably presses against the support surface 1b of the tube plate 1 and thereby produces a pressure-tight connection between the tube 2 and the tube plate 1.
  • a sealing ring 4 can be inserted as shown in FIG. 2 between tube 2 and tube plate 1.
  • this sealing ring 4 which may be an O-ring, for example, either by bevels (as in the left part of Fig. 2) or by step-like boring (as in the right part of Fig. 2) the necessary installation space can be created.
  • FIG. 3 shows a further possible embodiment.
  • the tube 2 made of plastic is provided at its end with a flange 2a with a U-shaped cross section, which has been formed in the manner of a crimping operation by 180 ° and by simultaneous expansion of the tube end.
  • the annular bearing surface 1 b is provided by a kind of collar 1 d, which is formed within the bore 1 c.
  • the sealing ring 4 is disposed within the U-shaped cross-section of the flange 2a between this and the bearing surface 1b formed on the tube plate 1.
  • the plate-spring-like retaining ring 3 ensures that even with changing temperatures and pressures of the respective flange 2a of the tube 2 is reliably pressed against its support surface 1b on the tube plate 1 in order to achieve the necessary pressure-tight connection.
  • the heat exchange takes place, for example, between a liquid flowing in the tubes 2 and a gas flowing around the outside of the tubes 2. Should it be necessary in such heat exchangers or collectors to replace individual tubes 2, for example, due to damage, this is readily possible that the corresponding retaining rings 3 removed, the tubes 2 removed and replaced by new tubes 2 and then corresponding retaining rings be used. Also, a short-term closure of defective pipes in burned Crutationdem heat exchanger operation is possible in a simple manner, that in the corresponding bore 1c in the tube plate 1 fitting plugs are used.
