Title
(DE) VORRATSTANK ZUR BEVORRATUNG EINES GEFRIERFÄHIGEN BETRIEBS- ODER HILFSSTOFFS
(EN) STORAGE TANK FOR STORING A FREEZABLE OPERATING AGENT OR AUXILIARY AGENT
(FR) RÉSERVOIR POUR LE STOCKAGE D’UN AGENT DE FONCTIONNEMENT OU AGENT AUXILIAIRE POUVANT ÊTRE CONGELÉ
Abstract
(DE)
Die Erfindung betrifft einen Vorratstank (1) zur Bevorratung eines gefrierfähigen Betriebs- oder Hilfsstoffs (2), insbesondere eines Reduktionsmittels zur Nachbehandlung von Abgasen eines Verbrennungsmotors, umfassend ein Tankvolumen (6) zur Aufnahme des gefrierfähigen Betriebs- oder Hilfsstoffs (2) sowie einen Heizkreislauf (7) zur Erwärmung des im Tankvolumen (6) aufgenommenen gefrierfähigen Betriebs- oder Hilfsstoffs (2). Erfindungsgemäß ist der Heizkreislauf (7) geschlossen ausgeführt und mit einem Wärmeträgerfluid befüllt, das durch eine als Wand (3) oder Boden (4) ausgebildete Begrenzung (5) des Tankvolumens (6) und/oder ein Rohr (8) vom im Tankvolumen (6) aufgenommenen Betriebs- oder Hilfsstoff (2) getrennt ist.
(EN)
The invention relates to a storage tank (1) for storing a freezable operating agent or auxiliary agent (2), in particular a reductant for the aftertreatment of exhaust gases of an internal combustion engine, comprising a tank volume (6) for holding the freezable operating agent or auxiliary agent (2) and a heating circuit (7) for heating the freezable operating agent or auxiliary agent (2) held in the tank volume (6). According to the invention, the heating circuit (7) is closed and is filled with a heat-transfer fluid, which is separated from the operating agent or auxiliary agent (2) held in the tank volume (6) by a boundary (5) of the tank volume (6) designed as a wall (3) or a bottom (4) and/or by a tube (8).
(FR)
La présente invention concerne un réservoir (1) pour le stockage d’un agent de fonctionnement ou agent auxiliaire (2) pouvant être congelé, notamment d’un agent réducteur pour le post-traitement de gaz d’échappement d’un moteur à combustion interne, le réservoir présentant un volume de réservoir (6) destiné à prendre en charge l’agent de fonctionnement ou l'agent auxiliaire (2) pouvant être congelé, ainsi qu’un circuit de chauffage (7) pour chauffer l’agent de fonctionnement ou l’agent auxiliaire (2) pouvant être congelé contenu dans le volume de réservoir (6). Selon l’invention, le circuit de chauffage (7) est réalisé de manière fermée et rempli d’un fluide caloporteur qui est séparé de l'agent de focntionnement ou de l'agent auxiliaire (2) contenu dans le volume de réservoir (6) par une délimitation (5) du volume de réservoir (6) se présentant sous la forme d’une paroi (3) ou d’un fond (4), ou et/ou par un tube (8).
