Beschreibung description

Die vorliegende Erfindung bezieht sich auf ein Verfahren zur Herstellung einer Röhrenheizvor-richtung, eine Röhrenheizvorrichtung sowie eine Verwendung der Röhrenheizvorrichtung. The present invention relates to a method for producing a tube heater, a tube heater and a use of the tube heater.

Aufgabe der vorliegenden Erfindung ist es ein rationelles Verfahren zur Herstellung einer Röhrenheizvorrichtung zu schaffen. Dies wird erfin-dungsgemäss dadurch erzielt, dass einzelne Röhrenheizelemente jeweils in beiden Endbereichen umgebogen werden, die Elementenden zur Vornahme einer Buckelschweissung entsprechend geformt und die derart geformten Enden der Elemente mit in zwei Kollektorrohren vorgesehenen Öffnungen durch Buckelschweissungen verschweisst werden. The object of the present invention is to provide a rational method for producing a tube heating device. This is achieved according to the invention by bending individual tube heating elements in each of the two end regions, shaping the ends of the elements accordingly to carry out a projection weld and welding the ends of the elements shaped in this way to openings provided in two collector tubes by projection welds.

Bevorzugte Verfahrensschritte ergeben sich aus den abhängigen Ansprüchen. Preferred process steps result from the dependent claims.

Im folgenden wird anhand der beiliegenden Zeichnung ein Ausführungsbeispiel der Erfindung sowie dessen Verwendungen näher beschrieben. Es zeigen: An exemplary embodiment of the invention and its uses are described in more detail below with reference to the accompanying drawing. Show it:

Fig. 1 ein Stahlrohr aus Ausgangsprodukt für ein Röhrenheizelement, 1 is a steel tube from the starting product for a tube heating element,

Fig. 2 das in seinen Endbereichen umgebogene Röhrenheizelement, 2 the tubular heating element bent over in its end regions,

Fig. 3 das an seinen Enden durch Einziehen bearbeitete, umgebogene Röhrenheizelement, 3 the bent tube heating element processed at its ends by drawing in,

Fig. 4 das mit Kollektorrohren verschweisste Röhrenheizelement, 4 shows the tube heating element welded to collector tubes,

Fig. 5 eine Röhrenheizvorrichtung, 5 shows a tube heating device,

Fig. 6 einen Schnitt durch das Kollektorrohr sowie eine Ansicht des durch Einziehen geformten Endes des Röhrenheizeiementes, 6 shows a section through the collector tube and a view of the end of the tubular heating element formed by drawing in,

Fig. 7 das mit dem Kollektorrohr verschweisste Ende des Röhrenheizelementes. 7 shows the end of the tube heating element welded to the collector tube.

In Fig. 1 ist das als Ausgangsprodukt zur Herstellung eines geeigneten Röhrenheizelementes verwendete Stahlrohr 1 dargestellt. 1 shows the steel tube 1 used as the starting product for the production of a suitable tubular heating element.

Aus Fig. 2 ist das in seinen Endbereichen 2 und 3 abgebogene Stahlrohr 1 ersichtlich. Das Abbiegen ermöglicht eine rationelle Buckelschweissung. 2 shows the steel pipe 1 bent in its end regions 2 and 3. The turning enables a rational projection welding.

In Fig. 3 ist das an seinen Enden 4 und 5 durch Einziehen bearbeitete Röhrenheizelement ersichtlich. In Fig. 3, the tubular heating element machined at its ends 4 and 5 can be seen.

Aus Fig. 4 ist das an seinen Enden 4 und 5 mit Kollektorrohren 6 und 7 verschweisste Röhrenheizelement ersichtlich. 4 shows the tube heating element welded at its ends 4 and 5 to collector tubes 6 and 7.

In Fig. 5 ist eine aus den Kollektorrohren 6 und 7 sowie mehreren Röhrenheizelementen 1 gebildete Röhrenheizvorrichtung 8 dargestellt. 5 shows a tube heating device 8 formed from the collector tubes 6 and 7 and a plurality of tube heating elements 1.

Aus Fig. 6 ist ein Querschnitt durch ein Kollektorrohr 6 sowie eine Ansicht des umgebogenen Bereiches 2 und des durch Einziehen geformten Endes 4 des Heizelementes dargestellt. 6 shows a cross section through a collector tube 6 and a view of the bent region 2 and of the end 4 of the heating element formed by drawing in.

Im Kollektorrohr ist eine Öffnung 9 vorgesehen, mit deren Rändern das Ende 4 des Röhrenheizelementes, wie in Fig. 7 dargestellt, durch Buckelschweissung verschweisst wird. Der Vorteil der Buckelschweissung liegt darin, dass die beiden Enden 4 und 5 des Röhrenheizelementes gleichzeitig mit den in den Kollektorrohren 6 und 7 vorgesehenen Öffnungen verschweisst werden können. An opening 9 is provided in the collector tube, with the edges of which the end 4 of the tube heating element, as shown in FIG. 7, is welded by projection welding. The advantage of the projection welding is that the two ends 4 and 5 of the tube heating element can be welded simultaneously with the openings provided in the collector tubes 6 and 7.

Die aus den Kollektorrohren 6 und 7 und mehreren einzelnen Röhrenheizeiementen 1 bestehende Röhrenheizvorrichtung 8 findet vorzugsweise Verwendung als Handtuchtrockner. Als Heizmedium kann entweder Warmwasser verwendet werden oder es können elektrische Heizstäbe und als Medium Öl verwendet werden. The tube heating device 8 consisting of the collector tubes 6 and 7 and several individual tube heating elements 1 is preferably used as a towel dryer. Either hot water can be used as the heating medium or electric heating elements and oil can be used as the medium.
