Abstract
Es wird eine Baueinheit (9) eines Behälters (1) zur Bevorratung einer gefrierfähigen Flüssigkeit, insbesondere eines Hilfsmittels (15) zur Verwendung im Rahmen einer Abgasnachbehandlung, beispielsweise einer selektiven katalytischen Reduktion von Stickoxiden, vorgeschlagen, mit einer Heizeinrichtung (17) zum bedarfsweisen Auftauen der Flüssigkeit, wobei die Baueinheit einen Meßfühler (19) zur Erfassung einer Temperatur im Behälter (1) aufweist, wobei der Meßfühler (19) derart angeordnet ist, daß der Meßfühler (19) zur Vermeidung einer chemischen Beeinflussung durch das Hilfsmittel mit dem Hilfsmittel nicht in Kontakt kommt.It is a structural unit (9) of a container (1) for storing a freezable liquid, in particular an aid (15) for use in an exhaust aftertreatment, for example, a selective catalytic reduction of nitrogen oxides, proposed with a heating device (17) for need-thawing the liquid, wherein the assembly comprises a sensor (19) for detecting a temperature in the container (1), wherein the sensor (19) is arranged such that the sensor (19) for avoiding chemical interference by the aid with the aid not comes into contact.
Description
Stand der TechnikState of the art
Die Erfindung geht aus von einer Baueinheit eines Behälters zur Bevorratung einer Flüssigkeit nach der Gattung des unabhängigen Anspruchs. Es ist schon eine derartige Baueinheit aus der
Abgasnachbehandlungsanordnungen mit Komponenten zur selektiven katalytischen Reduktion von Stickoxiden weisen einen Vorratsbehälter zur Aufbewahrung eines flüssigen Reduktionsmittels, zum Beispiel einer wässrigen Harnstofflösung, auf, welches mittels einer Tankheizung bei tiefen Außentemperaturen aufgetaut werden kann. Eine solche Tankheizung weist in bekannten Anordnungen zur Abgasnachbehandlung, wie beispielsweise in der
Offenbarung der ErfindungDisclosure of the invention
Die erfindungsgemäße Baueinheit eines Behälters zur Bevorratung einer Flüssigkeit mit den kennzeichnenden Merkmalen des unabhängigen Anspruchs hat demgegenüber den Vorteil einer robusten Messung der Temperatur insbesondere im beheizten Zustand, wodurch eine zuverlässige Regelung einer Heizeinrichtung der Baueinheit ermöglicht wird.The structural unit according to the invention of a container for storing a liquid with the characterizing features of the independent claim has the advantage of a robust measurement of the temperature, in particular in the heated state, whereby a reliable control of a heater of the assembly is made possible.
Durch die in den abhängigen Ansprüchen aufgeführten Maßnahmen sind vorteilhafte Weiterbildungen und Verbesserungen der im unabhängigen Anspruch angegebenen Baueinheit möglich. The measures listed in the dependent claims advantageous refinements and improvements of the independent claim unit are possible.
Besonders vorteilhaft ist eine Anordnung eines Meßfühlers zur Temperaturmessung nahe der, insbesondere möglichst nahe der bzw. an der wärmsten Stelle der Heizeinrichtung, so daß in idealer Weise die maximale Temperatur der Heizeinrichtung erfaßt werden kann. Hierdurch wird es möglich, im Unterschied zu PTC-Heizelementen leistungsstarke und flexible ohmsche Heizelemente für die Heizeinrichtung einzusetzen, deren ohmscher Widerstand keine signifikante Zunahme mit steigender Temperatur aufweist. Diese Eigenschaft haben eine Vielzahl von Materialien, beispielsweise auch Stahl. Eine erforderliche Regelung des Heizstroms solcher ohmschen Heizer, die sich in ihrer Heizleistung bei hohen Temperaturen nicht selbst begrenzen und im schlimmsten Fall überhitzen würden, kann durch Erfassen der heißesten Temperatur der Heizeinrichtung optimal eingestellt werden, so daß die Baueinheit mit einer leistungsstarken Heizeinrichtung beheizt wird, ohne jedoch zu überhitzen. Particularly advantageous is an arrangement of a sensor for temperature measurement near the, in particular as close to or at the warmest point of the heater, so that in an ideal manner, the maximum temperature of the heater can be detected. This makes it possible, unlike PTC heating elements to use powerful and flexible ohmic heating elements for the heater whose ohmic resistance has no significant increase with increasing temperature. This property has a variety of materials, including steel. A required control of the heating current of such ohmic heaters, which would not limit themselves in their heat output at high temperatures and would overheat in the worst case, can be optimally adjusted by detecting the hottest temperature of the heater, so that the assembly is heated with a powerful heater, but without overheating.

Ausführungsformen der ErfindungEmbodiments of the invention
Eine in einem Vorratsbehälter
In vorteilhafter Weise wird der Temperatursensor also in einem Rohr verbaut, das an dem Einsatzboden bzw. der Grundplatte
Das Rohr bzw. der Schlauch
Der Schlauch bzw. das Rohrstück kann aus einem flexiblen, für AdBlue undurchlässigen Kunststoff (z.B. PA, EPDM, HNBR) oder einem starren, für AdBlue undurchlässigen Kunststoff (HDPE) bestehen. Alternativ kann das Rohrstück aus Edelstahl aufgebaut sein. Edelstahl hat den Vorteil eines guten Wärmeüberganges. Auf diese Weise folgt der Sensor sehr schnell den Temperaturänderungen in seiner Umgebung. The tubing may be made of a flexible AdBlue impermeable plastic (e.g., PA, EPDM, HNBR) or a rigid AdBlue impermeable plastic (HDPE). Alternatively, the pipe section may be constructed of stainless steel. Stainless steel has the advantage of a good heat transfer. In this way, the sensor follows very quickly the temperature changes in its environment.
