Abstract

Die vorliegende Erfindung betrifft einen Abgaskühler (1), insbesondere für eine Abgasrückführung einer Brennkraftmaschine, vorzugsweise eines Kraftfahrzeugs, umfassend einen Abgaseinlass (2), der mit einer Einlasskammer (4) kommunizierend verbunden ist, einen Abgasauslass (3), der mit einer Auslasskammer (5) kommunizierend verbunden ist, mehrere Abgasrohren (7), die als Flachrohre ausgestaltet sind, die sich parallel zueinander durch eine Kühlmittelkammer (8) erstrecken und die einerseits mit der Einlasskammer (4) und andererseits mit der Auslasskammer (5) kommunizierend verbunden sind, einen Kühlmitteleinlass (9), der mit der Kühlmittelkammer (8) kommunizierend verbunden ist, und einen Kühlmittelauslass (10), der mit der Kühlmittelkammer (8) kommunizierend verbunden ist. Die Abgasrohre (7) weisen an sich gegenüberliegenden Seiten (28) mehrere, nach außen abstehende Ausbuchtungen (29) auf, die in der Längsrichtung (30) der Abgasrohre (7) voneinander beabstandet sind.The present invention relates to an exhaust gas cooler (1), in particular for exhaust gas recirculation of an internal combustion engine, preferably of a motor vehicle, comprising an exhaust gas inlet (2) communicating with an inlet chamber (4), an exhaust gas outlet (3) connected to an outlet chamber (3). 5) communicatingly connected, a plurality of exhaust pipes (7) which are configured as flat tubes which extend parallel to each other through a coolant chamber (8) and communicating on the one hand with the inlet chamber (4) and on the other hand with the outlet chamber (5), a coolant inlet (9) communicatively connected to the coolant chamber (8), and a coolant outlet (10) communicatively connected to the coolant chamber (8). The exhaust pipes (7) have on opposite sides (28) a plurality of outwardly projecting bulges (29) which are spaced apart in the longitudinal direction (30) of the exhaust pipes (7).

Eine vereinfachte Kühlwirkung lässt sich erreichen, wenn bei jeweils zwei benachbarten Abgasrohren (7) die Ausbuchtungen (29) des einen Abgasrohrs (7) jeweils in der Längsrichtung (30) der Abgasrohre (7) beabstandet zur nächstliegenden Ausbuchtung (29) des anderen Abgasrohrs (7) direkt am anderen Abgasrohr (7) anliegen.

Figure imgaf001
A simplified cooling effect can be achieved if in each case two adjacent exhaust pipes (7) the bulges (29) of the one exhaust pipe (7) in each case in the longitudinal direction (30) of the exhaust pipes (7) spaced from the nearest bulge (29) of the other exhaust pipe ( 7) directly against the other exhaust pipe (7).
