Elektrischer RohrheizkörperElectric tubular heater
Die Erfindung bezieht sich auf einen elektrischen Rohrheizkörper, in dessen Mantelrohr ein Isolierrohr angeordnet ist, das eine körnige Füllmasse und eine Heizwendel umschließt.The invention relates to an electrical tubular heater, in the jacket tube of which an insulating tube is arranged is, which encloses a granular filling compound and a heating coil.
Bei einem bekannten elektrischen Rohrheizkörper der vorstehenden Art besteht das Isolierrohr in der Hauptsache aus Speckstein. Die Verwendung von Speckstein als Isolierrohrmaterial ist jedoch nur möglich, wenn das E1UIlmaterial nicht durch Querschnittsverminderung des Mantelrohres verdichtet wird. Hierbei würde das Isolierrohr zerstört und seine Isolierwirkung weitgehend aufgehoben (DT-PS 713 794).In a known electric tubular heater of the above type, the insulating tube consists mainly of soapstone. The use of soapstone as insulating pipe material is only possible, however, if the E 1 material is not compacted by reducing the cross section of the jacket pipe. This would destroy the insulating tube and largely cancel its insulating effect (DT-PS 713 794).

lierwirkung des Isolierrohres erhalten bleibt.insulating effect of the insulating tube is retained.
Die gestellte Aufgabe wird dadurch gelöst, daß das Isolierrohr aus einem temperaturfesten Kunststoff, beispielsweise Polytetraflucraethylen besteht. Eine solches Material behält bei der Querschnittsverminderung des Mantelrohres seine guten elektrischen Isoliereigenschaften und seine thermische Widerstandsfähigkeit.The problem posed is achieved in that the insulating tube is made of a temperature-resistant plastic, for example Polytetraflucraethylene is made. Such a material is retained when the jacket pipe is reduced in cross-section its good electrical insulation properties and its thermal resistance.
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung rein schematisch dargestellt, die einen Längsschnitt durch einen Teil eines elektrischen Rohrheizkörpers zeigt.An embodiment of the invention is shown in the drawing shown purely schematically, showing a longitudinal section through part of an electric tubular heater.
Der elektrische Rohrheizkörper besitzt ein Mantelrohr 1, in dem ein Isolierrohr 2 aus Polytetrafluoraethylen o.dgl. angeordnet ist. Das Isolierrohr 2 umschließt eine Füllmasse 3 und eine hierin eingebettete Heizwendel 4, die an einem Anschlußbolzen 5 befestigt ist, der aus dem Kantelrohr 1 herausragt. Dieses ist durch einen Stopfen 6 verschlossen, der zentrisch vom Anschlußbolzen 5 durchgriffen ist.The electric tubular heater has a jacket tube 1, in which an insulating tube 2 made of polytetrafluoroethylene or the like. is arranged. The insulating tube 2 encloses a filling compound 3 and a heating coil 4 embedded therein, which is attached to a connecting bolt 5, which consists of the Cantilever tube 1 protrudes. This is closed by a plug 6 through which the connecting bolt 5 penetrates centrally is.
