Elektrisches HeizelementElectric heating element
Die Erfindung bezieht sich auf ein elektrisches Heizelement nach dem Oberbegriff des Anspruches 1.The invention relates to an electrical heating element according to the preamble of claim 1.
Es ist bereits ein elektrisches Heizelement der im Oberbegriff des Anspruches 1 genannten Art vorgeschlagen worden. Hierbei ist als Isolation eine körnige keramische Masse vorgesehen, wie sie beispiels-Λ weise auch bei den heute üblichen elektrischen Rohrheizkörpern verwendet wird, deren HeizwiderstandAn electrical heating element of the type mentioned in the preamble of claim 1 has already been proposed been. Here, a granular ceramic mass is provided as insulation, as it is for example Λ wisely, their heating resistance is also used in today's electric tubular heaters

Insulating compounds made of ceramic material provide a proportionate amount of heat dissipation high resistance, which can easily be accepted with tubular heaters.
Bei Heizelementen der im Oberbegriff des Anspruches 1 genannten Art kommt es aber darauf an, der aus den Widerstandskörpern fließenden Wärme,zu Gunsten eines guten Wirkungsgrades,einen möglichst geringen Widerstand entgegenzusetzen. Je geringer das Wärmegefälle ist, desto mehr Wärme kann den WiderstandskörpernIn the case of heating elements of the type mentioned in the preamble of claim 1, it depends on the from the Resistance bodies flow heat, in favor of a good degree of efficiency, the lowest possible resistance to oppose. The lower the heat gradient, the more heat the resistance bodies can hold

Aufgabe der Erfindung ist es daher, das Heizelement der im Oberbegriff des Anspruches 1 genannten Gattung hinsichtlich der Wärmeabfuhr besonders günstig zu gestalten. Der Wärmeabfuhr hinderliche Luftspalte sollen dabei weitgehend vermieden werden.The object of the invention is therefore to provide the heating element of the type mentioned in the preamble of claim 1 to make particularly favorable in terms of heat dissipation. Air gaps hindering heat dissipation should be avoided to a large extent.
Die gestellte Aufgabe wird erfindungsgemäß durch die im kennzeichnenden Teil des Anspruches 1 angegebene Ausbildung gelöst.The object set is according to the invention by those specified in the characterizing part of claim 1 Training solved.
Zweckmäßige Aus- und Weiterbildungen des Erfindungsgegenstandes sind in den Ansprüchen 2 und 3 angegeben. Appropriate training and further developments of the subject matter of the invention are specified in claims 2 and 3.
Die erfindungsgemäße Ausbildung hat den Vorteil, daß die im Mantelrohr angeordneten Elemente besonders satt aufeinanderliegen, so daß der Wärmeabfuhr1 hinderliehe Lufteinschlüsse senkrecht zu den breiten Seiten der Widerstandskörper weitgehend vermieden sind. Die verwendete Folie setzt der Wärmeabfuhr weit weniger Widerstand entgegen als körniges keramisches Material, ί bei dem eine die Stärke der Folie weit überschreiten-The design according to the invention has the advantage that the elements arranged in the jacket tube lie particularly tightly on top of one another, so that air pockets hindering the heat dissipation 1 perpendicular to the broad sides of the resistor body are largely avoided. The foil used has far less resistance to heat dissipation than granular ceramic material, ί in which one of the thickness of the foil is far greater-

Widerstandskörper aus kaltleitendem Material. Resistance body made of cold conductive material.
Bei dem in Fig. 1 dargestellten elektrischen Heizelement sind hintereinander angeordnete, gemäß Fig. 3 gestaltete flache Widerstandskörper 1 aus kaltleitendem Material, zwei jeweils auf einer breiten Seite der Widerstandskörper 1 aufliegende Stromleiter 2 und eine die Stromleiter 2 bedeckende Isolation 3 durch Querschnittsverminderung eines sie umgebenden Mantelrohres 4 aufeinandergepreßt.In the case of the electrical heating element shown in FIG. 1, according to FIG. 3, there are arranged one behind the other designed flat resistance body 1 made of cold-conducting material, two each on a wide side the resistance body 1 overlying current conductors 2 and an insulation 3 covering the current conductors 2 pressed against one another by reducing the cross section of a casing tube 4 surrounding them.
Die Isolation 3 besteht aus dünnen Folien oder Streifen, beispielsweise aus Glimmer oder einem ähnliche Eigenschaften wie Glimmer aufweisenden Material.The insulation 3 consists of thin foils or strips, for example made of mica or the like Properties like material containing mica.
Das Mantelrohr 4 ist derart flachgedrückt, daß zwischen seinen flachgedrückten Seiten die Teile 1,2 und 3 eingespannt sind (Fig.1).The jacket tube 4 is flattened in such a way that the parts 1, 2 between its flattened sides and 3 are clamped (Fig.1).
Das Mantelrohr 4 1st ferner beidseits der freien Flanken der Widerstandskörper 1 stärker zusammenge- ( drückt als im übrigen. The jacket tube 4 is also more strongly compressed ( pressed together than otherwise on both sides of the free flanks of the resistance body 1).

Nach Fig. 1 besitzen die stärker zusammengedrückten Flanken des Mantelrohres 4 eine etwa glockenförmige Kontur.According to Fig. 1, the more strongly compressed flanks of the jacket tube 4 have an approximately bell-shaped Contour.
Nach Fig.2, in der die Widerstandskörper, die Stromleiter und die Folien nicht eingezeichnet sind, ist die eine flachgedrückte Seite des hier mit 6 bezeichneten Mantelrohres durchgehend eben, im vorliegenden Fall also die untere Seite. Die dieser unteren Seite gegenüberliegende flachgedrückte Seite des Mantel-According to Fig.2, in which the resistance body, the current conductor and the foils are not shown, one of the flattened side of the one designated here by 6 is Casing pipe continuously flat, in the present case the lower side.
