Abstract

Die Erfindung betrifft einen Abgaswärmetauscher in einer Abgasrückführungsanordnung, der aus einem Plattenstapel besteht, der von einem Gehäuse (11) umgeben ist; in dem Plattenstapel bilden jeweils zwei an ihren Längsrändern (10) verbundene Platten (1) ein Flachrohr (2), das einen Turbulator (3) enthält, durch das bzw. den das Abgas strömt, wobei jeweils zwischen zwei Flachrohren (2) ein Kühlmittelkanal (5) angeordnet ist, der mit Strömungsleitelementen (6) ausgestattet ist. Um den Abgaswärmetauscher widerstandsfähiger gegen Temperaturwechselbelastungen zu gestalten, wurde erfindungsgemäß vorgesehen, dass
die Strömungsleitelemente (6) aus einer gewellten Platte (7) bestehen, in der Kanäle (13) mit Ein - und Austritten (14, 15) ausgebildet sind, wobei wenigstens einige der Kanäle (13) im Eintrittsbereich (20) des Kühlmittels einen ungeraden Verlauf aufweisen, und dass zwischen dem Plattenstapel und dem Gehäuse (11) Längenänderungen zugelassen werden.

The invention relates to an exhaust gas heat exchanger in an exhaust gas recirculation arrangement, which consists of a plate stack, which is surrounded by a housing (11); In the plate stack, in each case two plates (1) connected at their longitudinal edges (10) form a flat tube (2) which contains a turbulator (3) through which the exhaust gas flows, in each case between two flat tubes (2) a coolant channel (5) is arranged, which is equipped with flow guide elements (6). In order to make the exhaust gas heat exchanger more resistant to thermal cycling, it has been provided according to the invention
the flow guide elements (6) consist of a corrugated plate (7) in which channels (13) with inlets and outlets (14, 15) are formed, wherein at least some of the channels (13) are odd in the inlet area (20) of the coolant Have history, and that allowed between the plate stack and the housing (11) length changes.
