Abstract
Description
Die Erfindung betrifft einen mit integriertem Temperaturfühler ausgerüsteten Mantelrohrheizkörper gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to an with integrated temperature sensor equipped jacket tubular heater according to the preamble of Claim 1.
Derartige Rohrheizkörper werden vor allem zum Beheizen von Kunststoffspritzdüsen verwendet und dort in Form einer Wendel auf dem Düsenkörper angeordnet.Such tubular heaters are used primarily for heating Plastic spray nozzles used and there in the form of a spiral arranged on the nozzle body.
Einen solchen Rohrheizkörper offenbart beispielsweise das DE 79 32 598 U1. Dieser Heizkörper weist einen längs und parallel zur Heizwicklung angeordneten, zur Temperaturregelung dienen den Temperaturfühler auf. Die elektrischen Anschlüsse dieses Temperaturfühlers sind an derjenigen Seite des Heizkörpers an der sich auch die Anschlüsse der Heizwicklung befinden. Diese Anordnung wird jedoch problematisch, wenn der Heizkörper einen relativ kleinen Durchmesser aufweist und somit die erforderli chen Sicherheitsabstände zwischen der Heizwicklung und dem Me tallmantel nicht mehr einzuhalten sind.DE, for example, discloses such a tubular heater 79 32 598 U1. This radiator has a lengthways and parallel arranged for heating winding, serve for temperature control the temperature sensor. The electrical connections of this Temperature sensors are on the side of the radiator which are also the connections of the heating winding. This Arrangement, however, becomes problematic when the radiator is one has a relatively small diameter and thus the required Chen safety distances between the heating winding and the me tallmantel are no longer adhered to.
Demgegenüber zeigt die US-PS 3 746 838 einen Heizkörper mit ei nem termomechanisch arbeitenden Regler. Auch diese, nur bedingt biegefähige Bauart ist nicht geeignet für relativ kleine äußere Abmessungen des Mantelrohrheizkörpers.In contrast, US Pat. No. 3,746,838 shows a radiator with an egg a thermomechanical controller. This too, only to a limited extent flexible design is not suitable for relatively small external Dimensions of the tubular casing heater.
Zu diesem Stand der Technik wird auch noch auf die DE 33 43 822 C1 verwiesen, aus der jedoch im wesentlichen nur zu entnehmen ist, daß es bereits bekannt war, Mantelrohrheizkörper zusätz lich noch zu wendeln oder auch haarnadelförmig zu gestalten.This prior art is also referred to in DE 33 43 822 C1 referenced, but essentially only from the is that it was already known, additional tubular heating element Lich still to spiral or to make hairpin-shaped.
Aufgabe der vorliegenden Erfindung ist es, einen Mantelrohr heizkörper mit integriertem Temperaturfühler zu schaffen, bei dem der Meßort am Heizkörper frei wählbar ist und bei dem die erforderliche Hochspannungsfestigkeit auch bei sehr kleinen, möglichst noch unter 3 mm liegenden Außendurchmessern des Rohr heizkörpers gewährleistet werden kann.The object of the present invention is a jacket tube to create radiators with integrated temperature sensor at which the measuring point on the radiator is freely selectable and where required high voltage strength even with very small, if possible, the outside diameter of the pipe is still less than 3 mm radiator can be guaranteed.
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.
Der erfindungsgemäße Mantelrohrheizkörper ermöglicht es, auch bei sehr kleinen Außendurchmessern bis herunter auf 2 mm und weniger die erforderlichen Sicherheitsabstände zwischen der Heizwicklung und dem Metallmantel einzuhalten. Damit wird vor allem die Voraussetzung geschaffen für die Verwendung solcher Rohrheizkörper zur Beheizung auch sehr kleiner Düsen. Mantel rohrheizkörper mit diesen kleinen Durchmessern haben vor allem noch den Vorteil, daß sie sehr massearm sind und somit eine ge naue Temperaturregelung ermöglichen.The tubular casing heater according to the invention also makes it possible with very small outside diameters down to 2 mm and less the required safety distances between the Heating coil and the metal jacket. So that will all created the conditions for the use of such Tubular heating element for heating even very small nozzles. Coat tubular radiators with these small diameters have above all still the advantage that they are very low in mass and thus a ge enable accurate temperature control.
Der Gegenstand der Erfindung ist in einem Ausführungsbeispiel in der Zeichnung dargestellt und nachfolgend beschrieben.The object of the invention is in one embodiment shown in the drawing and described below.
Es zeigenShow it
Fig. 1 den Mantelrohrheizkörper in gestreckter Form, Fig. 1 shows the jacket tube radiators in elongated form,
Fig. 2 den Heizkörper gemäß Fig. 1 haarnadelförmig gestaltet und Fig. 2 designed the radiator of FIG. 1 hairpin-shaped and
Fig. 3 den zu einer Wendel geformten Rohrheizkörper. Fig. 3 shows the tubular heater formed into a coil.
Der dargestellte Rohrheizkörper besteht aus einem Metallmantel 1, einer in diesen Mantel 1 mittels verdichtetem Isoliermaterial 2 eingebetteten Heizwicklung 3 und aus einem in koaxialer Anord nung zur Heizwicklung 3 eingebetteten Termoelement 4. The tubular heater shown consists of a metal jacket 1 , a heating coil 3 embedded in this jacket 1 by means of compressed insulating material 2 and a thermocouple 4 embedded in a coaxial arrangement for heating coil 3 .
Die elektrischen Anschlüsse 5 des Termoelements 4 und die An schlüsse 6 der Heizwicklung 3 sind an den sich gegenüberliegen den Enden des Mantels 1 durch je einen Verschlußstopfen 7 in üblicher Weise aus dem Rohrheizkörper herausgeführt.The electrical connections 5 of the termocouple 4 and the connections 6 to the heating winding 3 are led out at the opposite ends of the jacket 1 by a sealing plug 7 in the usual manner from the tubular heater.
Wie die Fig. 2 zeigt, wird der zunächst gestreckte Rohrheiz körper 1-7 haarnadelförmig gebogen. Damit liegen, was in vie len Fällen erforderlich ist, die Anschlüsse 6 der Heizwicklung 3 und die Anschlüsse 5 des Termoelements 4 auf derselben Seite des Rohrheizkörpers.As shown in Fig. 2, the initially stretched tubular heater body 1-7 is bent hairpin-shaped. Thus, what is required in vie len cases, the connections 6 of the heating coil 3 and the connections 5 of the thermocouple 4 are on the same side of the tubular heater.
Nun wird der so geformte Rohrheizkörper 1-7 zu einer Wendel 8 gestaltet und kann in dieser Form auf einem entsprechenden Dü senkörper befestigt werden. Auch hier liegt der Anschluß 6 der Heizwicklung 3 auf derselben Seite wie der Anschluß 5 des Ter moelements 4.Now the tubular heater 1-7 shaped in this way is designed as a coil 8 and can be attached in this form to a corresponding nozzle body. Here, too, is the connection 6 of the heating winding 3 on the same side as the connection 5 of the ter moelements 4th
Der erfindungsgemäße Mantelrohrheizkörper kann im Rahmen die ser Erfindung je nach Bedarf variiert und so den technischen Gegebenheiten angepaßt werden. Dies gilt, wie schon erwähnt, vor allem auch hinsichtlich der Wahl des Meßpunktes am Mantel heizkörper.The tubular casing heater according to the invention can in the frame This invention varies as needed and so the technical Conditions to be adjusted. As already mentioned, this applies especially with regard to the choice of the measuring point on the jacket radiator.
