Abstract
Description
Die vorliegende Erfindung betrifft einen Abgas-Wärmeübertrager für eine Abgasanlage einer Brennkraftmaschine, insbesondere in einem Kraftfahrzeug mit den Merkmalen des Oberbegriffs des Anspruchs 1.The The present invention relates to an exhaust gas heat exchanger for one Exhaust system of an internal combustion engine, in particular in a motor vehicle with the features of the preamble of claim 1.
Aus
der
Der bekannte Abgas-Wärmeübertrager baut vergleichsweise groß. Insbesondere benötigt die Unterbringung der Steuerklappe im Einlassstutzen vergleichsweise viel Bauraum. Darüber hinaus führt die Abgasführung entweder ausschließlich durch den einen Kanal oder ausschließlich durch den anderen Kanal zwangsläufig zu großen Temperaturunterschieden zwischen den die Kanäle umhüllenden Rohren. Um die damit verbundenen thermischen Spannungen zu reduzieren, muss ein vergleichsweise hoher Aufwand getrieben werden.Of the known exhaust gas heat exchanger builds comparatively large. Especially needed the accommodation of the control flap in the inlet nozzle comparatively a lot of space. About that leads out the exhaust system either exclusively through one channel or only through the other channel inevitably too big Temperature differences between the tubes enveloping the channels. To those with it To reduce connected thermal stresses, a comparatively high expenditure to be driven.
Die vorliegende Erfindung beschäftigt sich mit dem Problem, für einen Abgas-Wärmeübertrager der eingangs genannten Art eine verbesserte Ausführungsform anzugeben, die sich insbesondere durch eine kompakte und vorzugsweise preiswerte Bauweise auszeichnet.The present invention employs dealing with the problem, for an exhaust gas heat exchanger of the type mentioned above to provide an improved embodiment, which in particular by a compact and preferably inexpensive construction distinguished.
Dieses Problem wird erfindungsgemäß durch den Gegenstand des unabhängigen Anspruchs gelöst. Vorteilhafte Ausführungsformen sind Gegenstand der abhängigen Ansprüche.This Problem is inventively the subject of the independent Claim solved. Advantageous embodiments are the subject of the dependent Claims.
Die Erfindung beruht auf dem allgemeinen Gedanken, die beiden Kanäle ineinander anzuordnen, so dass der eine Kanal den anderen Kanal umhüllt. Hierdurch ergibt sich zum einen eine besonders kompakte Bauweise für den Abgas-Wärmeübertrager. Zum anderen lassen sich die einzelnen Kanäle bei dieser Bauweise besonders einfach so aneinander anordnen, dass keine oder nur stark reduzierte thermische Spannungen auftreten. Gleichzeitig ist der vorgeschlagene Aufbau vergleichsweise preiswert.The Invention is based on the general idea, the two channels into each other so that one channel covers the other channel. hereby On the one hand results in a particularly compact design for the exhaust gas heat exchanger. On the other hand, the individual channels can be particularly in this construction simply arrange them so that no or only greatly reduced thermal Tensions occur. At the same time, the proposed structure comparatively inexpensive.
Vorzugsweise ist der Bypass-Kanal im Inneren des Wärmeübertrager-Kanals angeordnet. Bei dieser Sauweise vereinfacht sich die Steuerung der Abgasströmung. Diese Steuerung lässt sich beispielsweise mit Hilfe einer einzigen Steuerklappe realisieren, mit deren Hilfe der geometrisch einfache Querschnitt des innen liegenden Kanals, also des Bypass-Kanals geöffnet und gesperrt werden kann.Preferably the bypass channel is arranged inside the heat exchanger channel. In this way, the control of the exhaust gas flow is simplified. These Control leaves realize, for example, with the help of a single control flap, with their help the geometrically simple cross-section of the inside Channels, so the bypass channel can be opened and locked.
Entsprechend einer vorteilhaften Ausführungsform kann ein Einlassquerschnitt eines für den Wärmeübertrager-Kanal und den Bypass-Kanal gemeinsamen Abgaseinlasses oder eines Abgaseinlassabschnitts kleiner sein als ein Auslassquerschnitt eines Bypass-Auslasses oder eines Bypass-Auslassabschnitts. Diese Bauweise führt bei geöffnetem Bypass-Kanal zu einer erhöhten Strömungsgeschwindigkeit stromauf des Bypass-Einlasses. Hieraus resultiert ein Druckabfall am oder vor dem Bypass-Einlass, der eine Sogwirkung entfaltet und eine Ansaugströmung erzeugt. Hierdurch wird erreicht, dass die Abgase bei offenem Bypass-Kanal und bei offenem Wärmeübertrager-Kanal vorwiegend oder vorzugsweise ausschließlich durch den Bypass-Kanal strömen, obwohl der Wärmeübertrager-Kanal offen und somit grundsätzlich durchströmbar ist. Durch diese Auslegung ist nur ein einziges Steuerglied erforderlich, um eine im wesentlichen vollständige Durchströmung entweder des Bypass-Kanals oder des Wärmeübertrager-Kanals zu erzielen.Corresponding an advantageous embodiment may be an inlet cross-section of one for the heat exchanger channel and the bypass channel common exhaust inlet or a Abgaseinlassabschnitts smaller be as an outlet cross section of a bypass outlet or a Bypass outlet. This construction leads to an open bypass channel increased flow rate upstream of the bypass inlet. This results in a pressure drop on or in front of the bypass inlet, which develops a suction effect and generates a suction flow. This will ensures that the exhaust gases with open bypass channel and with open heat exchanger channel predominantly or preferably exclusively through the bypass channel stream, although the heat exchanger channel is open and thus in principle flow through is. This design requires only a single control element, to a substantially complete flow to achieve either the bypass channel or the heat exchanger channel.
