Abstract

Electrical heating elements which consist of a tubular heater and a profiled outer casing of aluminium, enclosing said tubular heater, can be produced in a simple manner and in a multiplicity of designs by using standard components. If such heating elements are to be suitable, however, for high operational temperatures, an outer casing of steel or steel alloys is necessary. Steel profiles, however, cannot be produced or can be produced only with great difficulty in the known design having a continuous hole. It was therefore the object of the present invention to provide the outer casing with a form which makes possible a simple construction of steel without the necessity of having to do without the advantages of the design using standard components. This object is solved according to the present invention in that the outer casing consists of two profiled casing parts (4, 10) which in cross-section are congruent, are formed from steel and which have in each case two opposite recesses (5 and 6, respectively) of semicircular cross-section which, when the profiled casing parts are placed against one another, receive and enclose the tubular heater (1) and which are provided with two frames (grooves, notches) (7) enclosing a recess (6) and two further recesses (8) which are arranged at the side of the second recess (5), correspond to the shape of the frame (7) and serve to receive said frames. <IMAGE>

Description

Die Erfindung betrifft ein elektrisches Heizelement gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to an electric heating element according to the Preamble of claim 1.

Derartige, aus einem Rohrheizkörper und einem, diesen umschlie­ ßenden, mit einem bestimmten Profil versehenen Außenmantel beste­ hende Heizelemente sind beispielsweise durch die DE-PS 33 03 983 bekannt. Diese haben den Vorteil, daß man, unter Verwendung von Standardbauteilen auf relativ einfache Art und Weise eine Viel­ zahl von Ausführungsarten von Heizelementen mit entsprechender vielseitiger Verwendbarkeit herstellen kann.Such, from a tubular heater and one, enclose this best outer jacket with a certain profile Heating elements are, for example, by DE-PS 33 03 983 known. These have the advantage that, using Standard components in a relatively simple way a lot Number of types of heating elements with corresponding can produce versatile usability.

Der, mit einer Aufnahmebohrung für den Rohrheizkörper versehene, profilierte Außenmantel läßt sich in dieser Form aber nur aus Aluminium od. dergl. auf wirtschaftliche Weise herstellen. Benö­ tigt man jedoch Heizelemente mit sehr hoher Temperaturbeständig­ keit, so ist die Verwendung von Stahl für den Außenmantel nicht zu umgehen.The one with a mounting hole for the tubular heating element profiled outer jacket can only be made in this form Produce aluminum or the like in an economical manner. Benö However, heating elements with a very high temperature resistance are used the use of steel for the outer jacket is not to get around.

Bekannt ist auch, wie die DE-AS 12 54 780 offenbart, ein elek­ trisches Heizelement, bei dem ein, oder mehrere Rohrheizkörper zwischen je zwei profilierte Außenmantelteile eingesetzt sind. Diese Außenmantelteile sind jedoch nicht formschlüssig mitei­ nander verbindbar und bilden somit keinen einheitlichen Außen­ mantel.It is also known how the DE-AS 12 54 780 discloses an elek trical heating element, in which one or more tubular heaters are inserted between two profiled outer jacket parts. However, these outer jacket parts are not form-fitting connectable and therefore do not form a unified outside coat.

Der Erfindung liegt die Aufgabe zugrunde, ein thermisch hoch belastbares Heizelement der vorgenannten Art zu schaffen, das auch bei Verwendung von Stahl für den Außenmantel, die Vorteile der Bauweise mit Standardbauelementen aufweist und dabei eine feste, formschlüssige und unlösbare Verbindung der Außenmantel­ teile miteinander ermöglicht. The invention has for its object a thermally high to create a resilient heating element of the aforementioned type  The advantages also when using steel for the outer jacket the construction with standard components and has a firm, positive and permanent connection of the outer jacket parts with each other.  

Diese Aufgabe wird durch die kennzeichnenden Merkmale des Pa­ tentanspruchs 1 gelöst.This task is characterized by the characteristic features of Pa claim 1 solved.

Das neuartige Heizelement ist, unter Verwendung von Standardbau­ elementen in verschiedenen Formen herstellbar und ist thermisch sehr hoch belastbar, so daß auch Strahlungsheizungen damit auf­ gebaut werden können.The new heating element is, using standard construction  elements can be produced in various forms and is thermal very resilient so that it can also be used for radiant heating can be built.

Die Erfindung ist in einem Ausführungsbeispiel anhand der Zeich­ nung erläutert und nachfolgend beschrieben.The invention is in one embodiment with reference to the drawing explained and described below.

Die Zeichnung stellt das erfindungsgemäße Heizelement im Quer­ schnitt dar.The drawing shows the heating element according to the invention in the transverse cut.

Das Heizelement besteht aus einem verdichteten Rohrheizkörper 1 an sich bekannter Art, bei dem eine Heizwendel 2 mittels ei­ nes Metalloxyds 9 in einem Stahlmantel 3 eingebettet ist und aus zwei deckungsgleichen Mantelprofilteilen 4 und 10 aus Stahl, die je zwei sich gegenüberliegende, im Querschnitt ungefähr halb­ kreisförmige Ausnehmungen 5 und 6 aufweisen, von denen die letz­ tere in zwei Zargen 7 übergeht, die die Ausnehmung 6 einschlie­ ßen. Beiderseits der dieser Ausnehmung 6 gegenüberliegenden Aus­ nehmung 5 sind zwei weitere Ausnehmungen 8 vorgesehen, die der Form der zuvor erwähnten Zargen 7 entsprechen.The heating element consists of a compressed tubular heater 1 known per se, in which a heating coil 2 is embedded by means of egg nes metal oxide 9 in a steel jacket 3 and two congruent jacket profile parts 4 and 10 made of steel, each two opposite, approximately half in cross section have circular recesses 5 and 6 , of which the last one merges into two frames 7 which include the recess 6 . On both sides of this recess 6 opposite recess 5 , two further recesses 8 are provided which correspond to the shape of the frames 7 mentioned above.

Bei der Montage des Heizelements werden jeweils zwei dieser Man­ telprofilteile 4 bzw. 10 gegeneinander gelegt, so daß der Rohr­ heizkörper 1 sich in der Ausnehmung 5 des einen Mantelprofilteils 10 und der Ausnehmung 6 des anderen Profilteils 4 befindet. Bei­ de Ausnehmungen 5 und 6 bilden zusammen einen Kreisquerschnitt.During the assembly of the heating element, two of these man profile sections 4 and 10 are placed against each other, so that the tubular heating element 1 is located in the recess 5 of a jacket section part 10 and the recess 6 of the other section part 4 . At the recesses 5 and 6 together form a circular cross section.

Nach dem Zusammenfügen dieser Teile werden die beiden Zargen 7 in Richtung der Pfeile 11 nach innen gepreßt und so eine form­ schlüssige, feste Verbindung der beiden Mantelprofilteile 4 und 10 geschaffen, die außerdem auch eine einwandfreie Wärmeübertra­ gung vom Rohrheizkörper zum Außenmantel sicherstellt.After assembling these parts, the two frames 7 are pressed in the direction of arrows 11 inwards, thus creating a form-fitting, firm connection of the two jacket profile parts 4 and 10 , which also ensures perfect heat transfer from the tubular heater to the outer jacket.

Selbstverständlich können auf die beschriebene Art und Weise auch beliebig viele Rohrheizkörper, beispielsweise zu einem groß­ flächigen Heizelement vereinigt, oder die Heizelemente zu ei­ ner Heizwendel, oder zu einer Heizspirale geformt werden.Of course you can in the way described any number of tubular heaters, for example one large flat heating element combined, or the heating elements to egg  ner heating coil, or be formed into a heating coil.
