Title (DE) TANKHEIZUNG
(EN) TANK HEATER
(FR) SYSTEME DE CHAUFFAGE POUR RESERVOIR
Abstract:
(DE) Die Erfindung betrifft eine Tankheizung, insbesondere für einen Harnstoff tank einer Verbrennungskraftmaschine, umfassend: ein Gehäuse (2) , in dem mindestens ein PTC- Element angeordnet ist, eine elektrische Anschlußleitung (3, 4), die an das PTC-Element angeschlossen ist, um einen Heizstrom durch das PTC-Element zu leiten, ein Ansaugrohr (5) zum Fördern von Flüssigkeit, wobei zumindest ein Abschnitt der elektrischen Anschlußleitung (5) als Widerstandsheizelement ausgebildet ist, der mit dem Innenraum des Ansaugrohrs (5) in wärmeleitender Verbindung steht .
(EN) The invention relates to a tank heater, especially for a urea tank of an internal combustion engine, comprising a housing (2) in which at least one PTC element is arranged, an electrical connecting cable (3, 4) that is joined to the PTC element so as to conduct a heating current through the PTC element, and an intake pipe (5) for conveying liquid. At least one section of the electrical connecting cable (5) is embodied as a resistive heating element which is connected in a thermally conducting manner to the interior of the intake pipe (5).
(FR) L'invention concerne un système de chauffage pour un réservoir, en particulier un réservoir d'urée d'un moteur à combustion interne, lequel système comprend un boîtier (2), dans lequel au moins un élément PTC est placé, une ligne de raccordement électrique (3, 4), raccordée à l'élément PTC pour faire passer un courant de chauffage à travers cet élément PTC, un tube d'aspiration (5) pour l'alimentation en liquide, au moins une section de la ligne de raccordement électrique (5) étant conçue sous la forme d'un élément de chauffage par résistance, en liaison thermoconductrice avec l'intérieur du tube d'aspiration (5).
