Definitions

  • the invention relates to a method for producing a tubular heater installation unit, in which the tubular heater ends are sealingly connected with a fastening plate provided with corresponding holes so that the connecting ends of the tubular heater are on the outside of the plate and the tubular heater itself is on the inside of the plate, and a Tubular radiator installation unit manufactured according to the method.
  • Tubular heaters generally consist of a jacket tube, e.g. B. made of chrome-nickel steel, one in an insulating compound, generally magnesium oxide, embedded heating coil and from the connecting parts.
  • the latter are generally connection bolts to which one end of the heating coil is welded.
  • the connection bolts are passed through an insulating bead or another isolating body which sits in the end section of the casing tube.
  • the jacket tube is now closed at its ends by means of an adhesive which, after curing, on the one hand protects the insulating material, that is to say the magnesium oxide, against the ingress of moisture and, on the other hand, improves the mechanical retention of the connecting bolt in the associated end of the jacket tube.
  • a sealing body made of elastic material and a counter flange plate movable on the tubular heating element leg can be applied before or after attaching the fastening plate.
  • the mounting plate or the counter flange plate carries a screw bolt.
  • the sealing body is pressed together by tightening a corresponding nut and is generally pressed against the edges of a container wall opening.
  • the fastening plate covering a container wall opening is screwed onto the container with the interposition of a sealing ring.
  • the tubular radiator installation units produced in this way can have different designs.
  • the invention is applicable to all constructions in which the tubular heater ends are passed through holes in a fastening plate and are fixed in a sealing manner therein.
  • the invention is based on the object of simplifying the manufacture of tubular heater installation units by improving the sealing of the tubular heater ends in the holes in the fastening plate, with a reject being almost completely avoided.
  • a hairpin-shaped tubular heater 1 consists of a Mar telrohr 2 and a filling of insulating material, for. B. of magnesium oxide 4.
  • the heating coil 3 is welded or soldered to a connecting bolt 5.
  • the Magnesiumoxidfulung 4 ends at a distance from the end edge 6 of the casing tube 2, so that an annular space 7 remains for receiving the end seal.
  • the annular space 7 is not closed in the new method. Rather, as shown in FIG. 1, the tubular heater ends are inserted through assigned holes 8 in a mounting plate 9 such that the end edge 6 protrudes somewhat beyond the outside of the mounting plate 9.
  • the fastening plate 9 preferably has a depression 10 in the region of the holes 8.
  • a welding electrode 11 of a capacitor welding device (not shown in detail) has a conical end 12, the smallest diameter at the cone end being smaller than the inside diameter of the jacket tube 2 and the diameter of the cone widening beyond the dimension of the outside diameter of the jacket tube 2.
  • the welding electrode 11 is hollow, as indicated at 13 in FIG. 2, so that it can accommodate the connecting bolt 5.
  • the welding electrode is now inserted into the open end of the tubular heating element as shown in FIG. 2, the end edge 6 being flanged out, as shown in FIG. 3.
  • the end edge 6 is welded to the edges of the hole 8.
  • a durable fixation is essential. Practice has shown, however, that both the fixation and the sealing are entirely satisfactory with the proposed method.
  • the annular space 7 is filled with an adhesive, as shown in FIG. 4, the adhesive plug 14 which forms extending at least over the flanged front edge 6 of the tubular heating element jacket 2.
  • the adhesive plug 14 which forms extending at least over the flanged front edge 6 of the tubular heating element jacket 2.
  • the entire depression 10 is filled with the adhesive. This creates the possibility of extensive automation. While, in known methods, care had to be taken to ensure that as little glue as possible. the The outer wall of the tubular heater reaches, because the sticking of adhesive residues made it difficult to insert into the holes in the mounting plate, the application of the adhesive is much less problematic in the described method.
  • the adhesive therefore fulfills two different functions: on the one hand, the end of the tubular heating element is protected against the ingress of moisture, and on the other hand, the passage of the casing tubes 2 of the tubular heating element 1 is sealed by the holes 8 in the fastening plate 9.
  • the magnesium oxide layer 4 can be protected against welding by means of an intermediate layer. It is only essential that an intermediate space remains, into which the welding electrode 11 can penetrate. Furthermore, insulating beads or similar connection elements can be used in the usual way.
  • the welding process can be varied accordingly.
  • the casing tube 2 of the tubular heater can have a larger diameter than the hole 8, the end edges 6 then being drawn in to the hole diameter.
  • the end edge 6 can be butt-welded to the underside of the mounting plate 9.
  • the hole 8 can be expressed conically downwards, while the end edge 6 of the tubular casing 2 is flared. The welding then takes place over the conical inclined surfaces.
  • the tube heater ends can be welded individually in the assigned holes. However, a plurality of welding electrodes 11 can also be used, which simultaneously weld the tubular heater ends in the assigned holes 8.
