The heater tube for motor vehicle exhaust gas heating has a plastic tube (1) over which a heating wire (2) is helically wound covered by a helically wound adhesive band (3) having adhesive on the underside only, insulating the second heater wire winding from the first.

Description

Elektrisch beheizbare Flüssigkeitsleitung, bei der auf einer inneren Kunststoffschicht ein Heizdraht angeordnet und um die Kunststoffschicht und den Heizdraht ein elektrisch isolierendes Band wendelförmig herumgewickelt ist.electrical heated liquid line, at arranged on a inner plastic layer, a heating wire and around the plastic layer and the heating wire an electrically insulating Ribbon helical is wrapped around.

Das bevorzugte Anwendungsgebiet der Flüssigkeitsleitung sind Harnstoffe, z.B. sogenanntes "AdBlue", die zur Abgasnachbehandlung dieselbetriebener Fahrzeuge in die Abgasleitung eingespritzt werden, um giftige NOx-Bestandteile zu normalen Bestandteilen der Luft, d.h. Stickstoff, Wasser und Kohlendioxid, zu reduzieren. Sie ist aber auch für Dieselkraftstoffe, Wasser, wie Kühl- oder Waschwasser, oder Bremsöl in Kraftfahrzeugen geeignet. Durch die Beheizung kann ein Einfrieren der Harnstoffe, Dieselkraftstoffe oder des Wassers verhindert und/oder eine Vorwärmung von Dieselkraftstoffen erreicht werden. Die Anwendung für Bremsöl verhindert eine zu hohe Viskosität des Bremsöls bei tieferen Temperaturen und damit eine Verlangsamung des Bremseingriffs.The preferred field of application of the liquid line is urea, eg so-called "AdBlue", which is injected into the exhaust pipe for exhaust aftertreatment of diesel-powered vehicles to reduce toxic NO x components to normal components of the air, ie nitrogen, water and carbon dioxide. But it is also suitable for diesel fuels, water, such as cooling or washing water, or brake oil in motor vehicles. By heating a freezing of urea, diesel fuel or water can be prevented and / or preheating of diesel fuels can be achieved. The application for brake oil prevents too high a viscosity of the brake oil at lower temperatures and thus a slowing of the braking intervention.

Bei einer bekannten, im Handel erhältlichen Flüssigkeitsleitung der eingangs genannten Art bestehen die Kunststoffschicht und das Band aus Kautschuk, und das Band wird an der Kautschukschicht anvulkanisiert, nachdem noch ein Verstärkungsgewebe zwischen beiden angeordnet wurde, um eine Aufweitung der Flüssigkeitsleitung bei hohen Drücken zu vermeiden.at a known, commercially available fluid line of the aforementioned type consist of the plastic layer and the Strip of rubber, and the strip is vulcanized to the rubber layer, after another reinforcing fabric between the two was arranged to widen the liquid line at high pressures to avoid.

Das Anvulkanisieren ist zeit- und energieaufwendig und demzufolge kostspielig.The Scanning is time and energy consuming and therefore expensive.

Der Erfindung liegt die Aufgabe zugrunde, eine Flüssigkeitsleitung der eingangs genannten Art anzugeben, die einfacher herstellbar ist.Of the Invention is based on the object, a liquid line of the above specify the type mentioned, which is easier to produce.

Erfindungsgemäß ist diese Aufgabe bei der eingangs erwähnten Flüssigkeitsleitung dadurch gelöst, daß das isolierende Band ein Klebeband ist, dessen Klebstoff mit der Kunststoffschicht verklebbar ist.According to the invention this is Task in the above-mentioned liquid line solved by that this insulating tape is an adhesive tape whose adhesive is attached to the plastic layer is glued.

Bei dieser Lösung kann die Kunststoffschicht auf einfache Weise, z.B. mittels eines Wickelautomaten oder sogar von Hand, gegebenenfalls mittels einer einfachen Wickelvorrichtung, mit dem Klebeband umwickelt werden.at this solution the plastic layer can be easily removed, e.g. by means of a Automatic winding machines or even by hand, if necessary by means of a simple winding device, are wrapped with the tape.

Vorzugsweise weist das Klebeband einen einseitig mit Klebstoff beschichteten Textilstreifen auf. Ein derartiges Klebeband hat eine hohe Zugfestigkeit und kann daher sehr fest aufgewickelt werden. Darüber hinaus ist seine nach dem Aufwickeln außen liegende Seite nicht klebfähig.Preferably the adhesive tape has a side coated with adhesive Textile strips on. Such an adhesive tape has a high tensile strength and therefore can be wound up very tightly. Furthermore its external side after winding is not tacky.

Der Heizdraht kann wendelförmig um die Kunststoffschicht herumgewickelt sein. Wegen der sich dadurch ergebenden räumlichen Konzentration ist die Heizleistung pro Fläche relativ hoch, so daß die Flüssigkeit auch bei relativ geringer Heizleistung rasch erwärmt wird. Diese hohe Heizleistung pro Fläche kann auch dadurch erreicht werden, daß der Heizdraht in Form einer Doppelwendel um die Kunststoffschicht herumgewickelt ist und einen elektrisch isolierenden Überzug aufweist. Die benachbarten Drahtabschnitte können daher relativ dicht nebeneinander verlaufen, ohne daß ein Kurzschluß entsteht.Of the Heating wire can be helical to be wrapped around the plastic layer. Because of that resulting spatial Concentration, the heating power per area is relatively high, so that the liquid is heated quickly even at relatively low heat output. This high heating power per area can also be achieved in that the heating wire in the form of a Double helix is wound around the plastic layer and a electrically insulating coating having. The adjacent wire sections can therefore be relatively close together run without a Short circuit arises.

Vorzugsweise bildet der Heizdraht eine Schlaufe. Die Schlaufe ermöglicht eine einfache Bewicklung der Kunststoffschicht mittels des Heizdrahtes, da die Hin- und Rückleitung gleichzeitig gewickelt werden kann.Preferably the heating wire forms a loop. The loop allows one easy wrapping of the plastic layer by means of the heating wire, because the return line can be wound at the same time.

Vorzugsweise sind die Enden des Heizdrahtes mit einem Stecker verbunden. Der Heizdraht kann daher auf einfache Weise mit einer Spannungsquelle verbunden werden.Preferably the ends of the heating wire are connected to a plug. Of the Heating wire can therefore easily with a voltage source get connected.

Die Erfindung und ihre Weiterbildungen werden nachstehend anhand der beiliegenden Zeichnungen bevorzugter Ausführungsbeispiele näher beschrieben. Darin stellen dar:The Invention and its developments are described below with reference to the attached drawings of preferred embodiments described in more detail. In it represent:

1 eine Seitenansicht eines ersten Ausführungsbeispiels einer erfindungsgemäßen elektrisch beheizbaren Flüssigkeitsleitung, 1 a side view of a first embodiment of an electrically heatable liquid line according to the invention,

2 eine Seitenansicht der Flüssigkeitsleitung nach 1 ohne das gemäß 2 außen herumgewickelte Klebeband, 2 a side view of the liquid line after 1 without that according to 2 externally wound adhesive tape,

3 eine Seitenansicht eines zweiten Ausführungsbeispiels einer erfindungsgemäßen Flüssigkeitsleitung, bei dem zur Verdeutlichung ebenfalls das erfindungsgemäß vorgesehene Klebeband weggelassen ist. 3 a side view of a second embodiment of a liquid conduit according to the invention, in which for clarity also the inventively provided adhesive tape is omitted.

Die in den 1 bis 3 dargestellten Flüssigkeitsleitungen haben innen eine rohr- oder schlauchartige, biegsame Kunststoffschicht 1, auf der ein Heizdraht 2 in Form eines Widerstandsdrahtes angeordnet ist. Bei beiden Ausführungsbeispielen ist um die Kunststoffschicht 1 und den Heizdraht 2 ein elektrisch isolierendes Band 3 wendelförmig herumgewickelt. In den 2 und 3 ist das Band 3 nicht dargestellt, um den Verlauf des Heizdrahtes 2 besser erkennen zu können.The in the 1 to 3 shown fluid lines have inside a tubular or hose-like, flexible plastic layer 1 on which a heating wire 2 is arranged in the form of a resistance wire. In both embodiments is the plastic layer 1 and the heating wire 2 an electrically insulating tape 3 helically wound around. In the 2 and 3 is the band 3 not shown, the course of the heating wire 2 to recognize better.

Das isolierende Band 3 ist ein Klebeband, dessen Klebstoff mit der Kunststoffschicht 1 verklebbar ist. Das Band 3 weist einen einseitig mit Klebstoff beschichteten Textilstreifen auf, der dem Band eine hohe Reißfestigkeit verleiht.The insulating tape 3 is an adhesive tape whose adhesive is attached to the plastic layer 1 is glued. The ribbon 3 has a one side adhesive coated fabric strip, which gives the tape a high tear resistance.

Bei dem Ausführungsbeispiel nach den 1 und 2 bildet der Heizdraht eine Schlaufe, die wendelförmig als Doppelwendel um die Kunststoffschicht 1 herumgewickelt ist.In the embodiment of the 1 and 2 the heating wire forms a loop, the helical as a double helix around the plastic layer 1 is wrapped around.

Auch bei dem Ausführungsbeispiel nach 3 bildet der Heizdraht 2 eine Schlaufe, deren Hin- und Rückleitungen jedoch aufeinander abgekehrten Seiten der Kunststoffschicht 1 geradlinig verlaufen.Also in the embodiment according to 3 forms the heating wire 2 a loop whose forward and return lines but facing each other sides of the plastic layer 1 run straight.

Der Heizdraht 2 ist mit einem elektrisch isolierenden Überzug aus Kunststoff versehen, so daß die Hin- und Rückleitungen bei dem Ausführungsbeispiel nach den 1 und 2 eng beieinander verlaufen können, aber ein Kurzschluß vermieden wird.The heating wire 2 is provided with an electrically insulating coating made of plastic, so that the forward and return lines in the embodiment of the 1 and 2 can run close to each other, but a short circuit is avoided.

Der wendelförmige Verlauf und die enge Nachbarschaft der Heizdrahtabschnitte erhöht die Wärmeleistung pro Flächeneinheit der Kunststoffschicht 1, so daß die durch die Flüssigkeitsleitung strömende Flüssigkeit rasch erwärmt werden kann.The helical profile and the close proximity of the Heizdrahtabschnitte increases the heat output per unit area of the plastic layer 1 so that the liquid flowing through the liquid conduit can be heated rapidly.

Die Enden des Heizdrahtes 2 sind mit einem Stecker 4 verbunden, der seinerseits mit einer Steckdose einer Spannungsquelle zusammengesteckt werden kann.The ends of the heating wire 2 are with a plug 4 connected, which in turn can be plugged together with a socket of a voltage source.

Die Ausbildung des isolierenden Bandes 3 als Klebeband vereinfacht die Herstellung der Flüssigkeitsleitung im Vergleich zu einer bekannten Flüssigkeitsleitung, bei der das isolierende Band an der Kunststoffschicht 1 anvulkanisiert ist. Das Umwickeln der Kunststoffschicht 1 mit dem Klebeband ist sehr einfach und rasch durchführbar. Eine anschließende Vulkanisierung entfällt.The formation of the insulating tape 3 as an adhesive tape simplifies the production of the liquid line compared to a known liquid line, in which the insulating tape on the plastic layer 1 is vulcanized. The wrapping of the plastic layer 1 with the tape is very easy and quick to carry out. A subsequent vulcanization is eliminated.
