Description

  

  Verfahren zur Herstellung elektrischer Heizkörper.    Es sind bereits     elektrische    Heizkörper  bekannt, bei welchen der Widerstandsdraht  in eine keramische     Isolationsmasse    einge  bettet und mit einem     Hohlkörper    umklei  det ist, welcher zwecks Zusammenpressung  der Isolationsmasse unter     Querschnittsver-          ringerung        zusammengedrückt    wird.

   Diese       Querschnittsverringerung    wurde entweder  durch Ziehen des gesamten Heizwiderstandes  durch ein Zieheisen oder durch     Eindrücken          bezw.    Einwalzen von Rillen in den Hohl  körper unter Anwendung eines von aussen  nach innen gerichteten Druckes erzielt.  



  Bei dem Heizkörper, der nach dem vor  liegenden Verfahren hergestellt wird, bleibt  die Form des äussern Hohlkörpers unver  ändert. Die Pressung der in einen Hohl  körper eingeführten, den Heizleiter umgeben  den losen Isolationsmasse wird durch An  ordnung eines von innen nach aussen gerich  teten Druckes hervorgerufen. Um diesen  Druck zu erzeugen, werden zweckmässig ein  oder mehrere Kerne in die     Isolationsmasse     eingetrieben,     bezw.    hindurchgezogen.    In der beiliegenden Zeichnung ist eine  Ausführungsform des Heizkörpers in     Fig.    1,  2 und 3 dargestellt.  



  Die     Fig.    1 zeigt den Heizkörper vor der  Druckbehandlung.     wobei    in dem Hohlkör  per a die keramische Isolationsmasse b den       Heizleiter    c lose umgibt;  Die     Fig.    2 zeigt, wie ein Kern     d    in die  Isolationsmasse unter     Zusammendrückung     derselben von innen nach aussen eingeführt  wird;  Die     Fig.    3 zeigt einen fertigen Heiz  körper.  



  Die vorher     loso        Isolationsmasse    ist durch  den ausserordentlich hohen     Durebzugdruck     so fest geworden, dass keine weitere innere       Armierung        nötig-    ist, welche ,jedoch,     falls     ein besonderer     Verwendungszweclr    sie erfor  derlich machen sollte, ohne weiteres ange  bracht werden könnte. \



  Method of manufacturing electric radiators. Electrical heating elements are already known in which the resistance wire is embedded in a ceramic insulation compound and covered with a hollow body which, for the purpose of compressing the insulation compound, is compressed with a reduction in cross section.

   This cross-sectional reduction was achieved either by pulling the entire heating resistor through a drawing iron or by pressing it in. Achieved rolling grooves into the hollow body using a pressure directed from the outside inwards.



  In the case of the radiator, which is manufactured according to the present process, the shape of the outer hollow body remains unchanged. The compression of the heat conductor, inserted into a hollow body and surrounding the loose insulation material, is brought about by a pressure directed from the inside to the outside. To generate this pressure, one or more cores are expediently driven into the insulation compound, respectively. pulled through. In the accompanying drawing, an embodiment of the heater in Figs. 1, 2 and 3 is shown.



  Fig. 1 shows the radiator before the pressure treatment. wherein in the Hohlkör by a, the ceramic insulation compound b loosely surrounds the heating conductor c; FIG. 2 shows how a core d is inserted into the insulation mass while compressing it from the inside outwards; Fig. 3 shows a finished heating body.



  The insulation compound that was previously loosened has become so firm due to the extraordinarily high tensile pressure that no further internal reinforcement is necessary, which, however, could easily be attached if a special purpose of use should make it necessary. \
