Description
DEUTSCHESGERMAN
Die Erfindung bezieht sich auf einen Rohrheizkörper mit mehreren Heizwendeln und ist dadurch gekennzeichnet, daß seine Heizwendieln als Gänge einer mehrgängigen Schraube gleichachsig zueinander und isoliert voneinander in der im wesentlichen keramisehen Isoliermasse eines vorzugsweise metallischen Rohres eingebettet sind und bei dem die beiden Enden jeder Heizwendel doppelpolig, also gleichzeitig an die Stromquelle angeschlossen werden bzw. von ihr abschaltbar sind. Derartige Rohrheizkörper haben gegenüber bekannten Ausführungen den Vorteil, daß eine Unterbringung der Heizwendeln auf geringstem Raum bei geringstem Durchmesser und bei kleinster Potentialdifferenz zwischen den benachbarten Gängen der ineinandergewickelten Heizwendeln eine hohe Überschlagsicherheit gewährleisten. Bei Gleichstrom wird man die Heiz wendeln des einen Rohrendes an den einen Pol (ζ. B. Pluspol) und die Heizwendeln des anderen Rohrendes an den anderen Pol (ζ. Β. Minuspol) anschließen.The invention relates to a tubular heater with several heating coils and is characterized in that that his Heizwendieln coaxially to each other and as threads of a multi-thread screw isolated from each other in the essentially ceramic insulating compound of a preferably metallic one Tube are embedded and in which the two ends of each heating coil are double-pole, i.e. at the same time to the Power source are connected or can be switched off from it. Such tubular heating elements have compared to known designs the advantage that an accommodation of the heating coils to the smallest Space with the smallest diameter and the smallest potential difference between the adjacent aisles of the heating coils wound into one another guarantee a high level of protection against rollover. With direct current the heating coils of one end of the pipe will be connected to one pole (ζ. B. positive pole) and the heating coils of the other end of the pipe to the other pole (ζ. Β. negative pole).
Die Erfindung wird im folgenden unter Hinweis auf ein in der Zeichnung dargestelltes Ausiührungsbeispiel beschrieben. Es zeigtThe invention is described below with reference to an exemplary embodiment shown in the drawing described. It shows

1 ist ein aus zunderbeständigem metallischem Werkstoff hergestelltes dünnwandiges Heizrohr, das
beispielsweise einen kleinen Durchmesser von etwa 6 mm haben kann. In diesem Rohr 1 sind zwei Heizwendeln
2, 3 (vgl. Fig. 2) derart ineinandergewickelt, daß sie die Gänge einer zweigängigen· Schraubenlinie
bilden. Die Abstände der einzelnen Gänge werden über die ganze Länge des Rohres dadurch konstant
gehalten, daß die Wendeln in eine feinkörnige, hitzebeständige Isoliermasse 5 eingebettet sind. Die vier
Enden 7, 8, 9, 10 der beiden Heizwendeln 2, 3 sind getrennt voneinander aus den beiden Enden des. Heizrohres
1 nach außen geführt, und zwar zu den Anschlußklemmen 11, 12, 13, 14 eines geeigneten Reglerschalters
15. Die Enden 7, 8, die aus dem einen Heizrohrende herausragen, sind unabhängig voneinander
zu den beiden Schalterklemmen 11, 12 geführt, die einzeln für sich oder gleichzeitig mit dem einen Pol
16 der elektrischen Zuleitung verbunden werden können. Entsprechendes gilt für die beiden aus dem
anderen Rohrende herausragenden Heiz wendel enden 9, 10 und den Schalterklemmen 13,14 sowie dem anderen
Pol 17 de» Leitungsnetzes. Dabei ist durch einen mit Rohrheizkörper
mit mehreren Heizwendeln1 is a thin-walled heating tube made of non-scaling metallic material, which can have a small diameter of about 6 mm, for example. In this tube 1, two heating coils 2, 3 (see FIG. 2) are wound into one another in such a way that they form the turns of a two-flight helix. The distances between the individual courses are kept constant over the entire length of the pipe in that the coils are embedded in a fine-grained, heat-resistant insulating compound 5. The four ends 7, 8, 9, 10 of the two heating coils 2, 3 are separated from each other from the two ends of the heating tube 1 to the outside, namely to the terminals 11, 12, 13, 14 of a suitable regulator switch 15. The ends 7, 8, which protrude from one end of the heating tube, are guided independently of one another to the two switch terminals 11, 12, which can be connected individually or simultaneously to one pole 16 of the electrical supply line. The same applies to the two ends protruding from the other pipe heating coil ends 9, 10 and the switch terminals 13, 14 and the other pole 17 of the »line network. This is done by a tubular heater
with several heating coils

einem Handgriff 18 versehenen aus Isolierstoff bestehenden Schaltknopf 19, welcher die beiden Schalterklemmen oder Kontakte 11,13 trägt, dafür gesorgt, daß die beiden Kontaktpaare 11, 16 und 13, 17 nur gleichzeitig geöffnet bzw. geschlossen werden können.a handle 18 provided made of insulating material switch button 19, which the two switch terminals or contacts 11,13 carries, it is ensured that the two contact pairs 11, 16 and 13, 17 only can be opened and closed at the same time.
Es wird demgemäß bei jeder Betätigung des Handgriffes 18 die eine Heizwendel 2 beidpolig ein- bzw. ausgeschaltet. Entsprechendes gilt für die andere Heizwendel 3, wenn am Handgriff 20 des aus Isolierstoff bestehenden Schaltsegments 21 die beiden auf ihm befestigten Schalterklemmen oder Kontakte 12, 14 mit den Kontakten 16, 17 gleichzeitig in oder außer Berührung kommt.Accordingly, each time the handle 18 is actuated, one heating coil 2 is switched on or off at both poles. switched off. The same applies to the other heating coil 3 when the handle 20 is made of insulating material existing switching segment 21 the two switch terminals or contacts 12 attached to it, 14 comes into or out of contact with the contacts 16, 17 at the same time.
Durch die beidpolige Ausschaltung des Heizelements 2 wird eine schädliche Potentialdifferenz zwisehen den Heizwendeln 2 und 3 dann vermieden, wenn die Heizwendel 3 durch Betätigen des Handgriffes 20 eingeschaltet wird. Entsprechendes gilt für die Heizwendel 3 beim Einschalten der Heizwendel 2. Bei Betätigung beider Handgriffe 18 und 20 werden beide Heizwendeln 2 und 3 gleichzeitig eingeschaltet. Bei Gleichstrom ist bloß darauf zu achten, daß die Heizwendel des einen Rohrendes an dem einen Pol (ζ. Β. Pluspol) und die Heizwendel des anderen Rohrendes an dem anderen Pol (gegebenenfalls dem Minuspol) angeschlossen wird, um jegliche Potentialdifferenzen zwischen den Gängen der einzelnen Heizwendeln zu vermeiden.The two-pole disconnection of the heating element 2 creates a harmful potential difference the heating coils 2 and 3 then avoided when the heating coil 3 by operating the handle 20 is switched on. The same applies to the heating coil 3 when the heating coil 2 is switched on both handles 18 and 20, both heating coils 2 and 3 are switched on at the same time. at Direct current just make sure that the heating coil of one end of the pipe is connected to one pole (ζ. Β. Positive pole) and the heating coil of the other pipe end on the other pole (possibly the negative pole) is connected to eliminate any potential differences between the corridors of the individual heating coils avoid.
