Abstract
Description
Die Erfindung betrifft eine Vorrichtung zum Temperieren einer Fluidleitung mit einer aus einem elastischen Material bestehenden Mantelleitung, die einen Längsschlitz aufweist zum Einsetzen der Fluidleitung in einen Hohlraum der Mantelleitung, so dass die Fluidleitung in der eingesetzten Position von einer inneren Umfangsfläche der Mantelleitung umfasst ist, wobei in der Mantelleitung mindestens ein Temperatursensor integriert angeordnet ist und wobei in der Mantelleitung mindestens ein sich in Längsrichtung derselben erstreckendes Heizelement angeordnet ist.The The invention relates to a device for tempering a fluid line with a sheathed cable consisting of an elastic material, which has a longitudinal slot for insertion of the fluid line in a cavity of the sheath line, so that the fluid line in the inserted position of an inner peripheral surface the sheathed cable is included, wherein in the sheathed cable at least a temperature sensor is arranged integrated and wherein in the sheath line at least one extending in the longitudinal direction thereof Heating element is arranged.

der
Aufgabe der vorliegenden Erfindung ist es, eine Vorrichtung zum Temperieren einer Fluidleitung derart weiterzubilden, dass die Effektivität der Wärmeeinleitung von einer die Fluidleitung umgebenden Mantelleitung in die Fluidleitung verbessert wird.task It is the object of the present invention to provide a device for tempering a fluid line in such a way that the effectiveness the heat input from a surrounding the fluid line sheath line is improved in the fluid line.
Zur Lösung dieser Aufgabe ist die Erfindung in Verbindung mit dem Oberbegriff des Patentanspruchs 1 dadurch gekennzeichnet, dass die Mantelleitung im Wesentlichen durch eine thermisch leitfähige Polymerschicht gebildet ist, in der mindestens ein Heizelement eingebettet ist.to Solution to this problem is the invention in connection with the preamble of claim 1, characterized in that the sheathed cable essentially by a thermally conductive Polymer layer is formed, embedded in the at least one heating element is.
Die besonderen Vorteile der Erfindung bestehen darin, dass zum einen der herstellungstechnische Aufwand, der für die Integration von Heizelementen in die Mantelleitung erforderlich ist, verringert und zum anderen eine homogene und umfassende Wärmeeinleitung an der inneren Umfangsfläche der Mantelleitung in die Fluidleitung ermöglicht werden. Durch die thermisch leitfähige Polymerschicht weist die Mantelleitung verbesserte Wärmeleiteigenschaften auf. Der Aufwand zum Einbringen der Wärmeenergie in die Mantellei tung kann verringert werden, da die Anzahl der Heizelemente auf vorzugsweise ein oder zwei Heizelemente begrenzt werden kann.The particular advantages of the invention are that on the one hand the manufacturing effort required for integration required by heating elements in the sheathed cable, and reduced on the other hand a homogeneous and comprehensive heat input on the inner peripheral surface of the sheath line in the fluid line be enabled. Due to the thermally conductive Polymer layer, the sheath line has improved thermal conduction properties on. The effort to introduce the heat energy in the Mantellei tion can be reduced, since the number of heating elements can be limited to preferably one or two heating elements.
Nach einer Weiterbildung der Erfindung ist an einer äußeren Umfangsfläche der thermisch leitfähigen Polymerschicht eine Isolationsschicht angeordnet, so dass einer unerwünschten Wärmeübertragung in einer radialen Richtung nach außen vorzugsweise entgegengewirkt wird.To a development of the invention is an outer Peripheral surface of the thermally conductive polymer layer an insulating layer arranged so that an undesirable Heat transfer in a radial direction outside is preferably counteracted.
Nach einer Weiterbildung der Erfindung ist die thermisch leitfähige Polymerschicht aus einem Elastomermaterial oder einem Thermoplastmaterial gebildet. Vorzugsweise wird ein Elastomer, vorzugsweise ein Silikonmaterial, mit einer relativ großen Wärmeleitfähigkeit verwandt, so dass die von dem Heizelement eingebrachte Wärmeenergie mit geringen Verlusten zu der zu erwärmenden Fluidleitung übertragen werden kann.To a development of the invention is the thermally conductive Polymer layer formed of an elastomeric material or a thermoplastic material. Preferably, an elastomer, preferably a silicone material, with a relatively high thermal conductivity used so that the heat energy introduced by the heating element transferred with low losses to the fluid line to be heated can be.
Nach einer Weiterbildung der Erfindung ist der aus einem Elastomermaterial gebildeten thermisch leitfähigen Polymerschicht ein die thermische Leitfähigkeit verbesserndes Additiv beigemischt, so dass die von dem Heizelement aufgebrachte Heizleistung verringert werden kann.To a development of the invention is made of an elastomeric material formed thermally conductive polymer layer a the added thermal conductivity-improving additive, so that the heating power applied by the heating element is reduced can be.
Nach einer Weiterbildung der Erfindung ist die Mantelleitung durch Koextrusion der thermisch leitfähigen Schicht und mindestens einer Isolierschicht hergestellt. Vorteilhaft kann hierdurch der Herstellungsaufwand verringert werden, da die Mantelleitung in einem Arbeitsschritt hergestellt werden kann. Dabei wird das vorzugsweise als Heizdraht ausgebildete Heizelement in die Extrudiervor richtung eingebracht, so dass die Polymerschicht unter Einbettung des Heizdrahtes aufextrudiert wird.To a development of the invention is the sheathed cable by coextrusion the thermally conductive layer and at least one Insulating layer produced. This can advantageously the production cost be reduced because the sheathed cable in one step can be produced. This is preferably designed as a heating wire Heating element introduced into the Extrudiervor direction, so that the Polymer layer is extruded under embedding of the heating wire.
Nach einer Weiterbildung der Erfindung sind mindestens zwei Heizelemente in der thermisch leitfähigen Polymerschicht integriert angeordnet, wobei die Heizelemente jeweils einem Schenkel der Mantelleitung zugeordnet sind. Vorzugsweise sind die Heizelemente symmetrisch zu einer den Längsschlitz schneidende Längsmittelebene der Mantelleitung angeordnet, so dass in beiden Schenkeln der Mantelleitung ein gleichmäßiger Wärmeeintrag ermöglicht wird.To a development of the invention are at least two heating elements integrated in the thermally conductive polymer layer arranged, wherein the heating elements each have a leg of the sheathed cable assigned. Preferably, the heating elements are symmetrical to a longitudinal center plane intersecting the longitudinal slot arranged the sheath line, so that in both legs of the sheathed cable a uniform heat input is possible.
Weitere Vorteile der Erfindung ergeben sich aus den weiteren Unteransprüchen.Further Advantages of the invention will become apparent from the other dependent claims.
