Abstract
Die Erfindung betrifft ein Heizelement auf der Basis graphitierter, koerniger Materialien und arbeitet nach dem Prinzip der Widerstandsheizung. Die Aufgabe, eine oekonomische Herstellung eines Heizelementes zu entwickeln, wird geloest, indem zwischen Elektroden beliebiger Form eine lose Schuettung des graphitierten Materials angeordnet ist.The invention relates to a heating element based on graphitic, koerniger materials and operates on the principle of resistance heating. The task of developing an economical production of a heating element is achieved by arranging a loose layer of the graphitized material between electrodes of any desired shape.

Nach DD-PS 60915 ist ein Verfahren zum schnellen Aufheizen von Gasen und Flüssigkeiten bekannt, wobei das aufzuheizende Medium durch den elektrischen Widerstandserhitzer hindurchgeführt wird. Dabei sind die Bauelemente Metalle, Metall-Legierungen oder durch Metallisierung leitend gemachte Nichtleiter (Al-Oxid, Quarz, Glas, organischer Kunststoff), die nadel-, stäbchen- oder bandförmig vorliegen und an den Berührungsstellen miteinander verkleben, verkitten oder versintern. Ein weiteres bekanntes Heizelement (DE-OS 2143710) besteht aus elektrisch leitenden, an Elektroden angeschlossenen und sich somit orwärmenden Materialien.According to DD-PS 60915 a method for rapid heating of gases and liquids is known, wherein the medium to be heated is passed through the electrical resistance heater. In this case, the components are metals, metal alloys or non-conductors made conductive by metallization (Al oxide, quartz, glass, organic plastic) which are in the form of needles, rods or bands and stick together, cemented or sintered at the contact points. Another known heating element (DE-OS 2143710) consists of electrically conductive, connected to electrodes and thus orwärmenden materials.
Fs werden hochpolymere SiC-Verbindungen, Kunststoff und Silbergraphit eingesetzt. Die Anordnung der Materialien zwischen den Elektroden erfolgt in der Weise, daß gleichmäßige Stromlinien entstehen.For example, high-polymer SiC compounds, plastic and silver graphite are used. The arrangement of the materials between the electrodes takes place in such a way that uniform streamlines arise.
