Description
Die Erfindung betrifft einen Abgaswärmeübertrager für einen Verbrennungsmotor, mit einem Bündel aus innen mit Wirbelerzeugern versehenen Strömungskanälen für Gas.The The invention relates to an exhaust gas heat exchanger for one Internal combustion engine, with a bundle from inside with vortex generators provided flow channels for gas.

Der Erfindung liegt die Aufgabe zugrunde, bei einem Abgaswärmeübertrager der eingangs genannten Art in möglichst wirtschaftlicher Weise die Strömungskanäle herzustellen.Of the Invention is based on the object in an exhaust gas heat exchanger of the type mentioned in as possible economical way to produce the flow channels.
Diese Aufgabe wird in Verbindung mit den Merkmalen des Oberbegriffs des Patentanspruchs 1 dadurch gelöst, daß die Strömungskanäle als Rohre ausgebildet sind, die aus jeweils einem Blechstreifen geformt sind, an welchem die Wirbelerzeuger angebracht sind.These Task becomes in connection with the characteristics of the generic term of the Patent claim 1 solved by that the Flow channels formed as tubes are, which are each formed of a sheet metal strip on which the vortex generators are attached.
Der Blechstreifen ist ferner mit nach außen ausgeprägten noppenförmigen Vorsprüngen versehen, die jeweils zwischen zwei hintereinander folgenden Paaren von Wirbelerzeugem angeordnet sind. Diese noppenförmigen Vorsprünge haben eine Höhe, die dem Abstand zu den benachbarten Rohren des Rohrbündels entspricht.Of the Sheet metal strip is also provided with outwardly pronounced knob-shaped projections, each between two successive pairs of vortex generators are arranged. This knob-shaped projections have a height, which corresponds to the distance to the adjacent tubes of the tube bundle.
In Ausgestaltung der Erfindung wird vorgesehen, daß die Blechstreifen mittels Abkanten zu Mehrkantrohren, insbesondere zu Sechskantrohren, geformt sind, die jeweils mittels einer Längsnaht verschweißt sind. Derartige Mehrkantrohre und insbesondere Sechskantrohre bieten eine gleichmäßige Durchströmung und ermöglichen es außerdem, zu sehr kompakten Rohrbündeln zusammengefaßt zu werden.In Embodiment of the invention it is provided that the metal strip by means Bending to polygonal tubes, in particular to hexagonal tubes shaped are, which are each welded by means of a longitudinal seam. Such polygonal tubes and in particular hexagonal tubes offer a uniform flow and enable it also to very compact tube bundles summarized to become.
Bei einer anderen Ausgestaltung wird vorgesehen, dass die Blechstreifen jeweils wendelförmig zu Rundrohren gewickelt und jeweils an einer wendelförmigen Längsnaht verschweißt oder verlötet sind. Derartige Rundrohre sind strömungstechnisch günstig, da sie eine gleichmäßige Durchströmung bei verhältnismäßig geringem Druckverlust ermöglichen. Darüber hinaus las sen sich derartige Rundrohre sehr kompakt zu einem Rohrbündel zusammenfassen.at Another embodiment provides that the metal strips each helical too Round tubes wound and each on a helical longitudinal seam welded or soldered. Such round tubes are aerodynamically favorable because they have a uniform flow at relatively low Allow pressure loss. Furthermore las sen such round tubes very compact to summarize a tube bundle.
