Exhaust gas heat exchanger, in particular exhaust gas cooler for exhaust gas recirculation in motor vehicles

摘要

The exchanger has heat exchanging conduits via which exhaust gases and coolant flow to distributing and/or collecting chambers. A flow guiding device (140) is arranged in the distributing and/or collecting chambers. The flow guiding device has exhaust gas inflow and discharge surfaces (150, 160) and a set of flow channels (170) that extends from the inflow surface to the discharge surface and is inclined with respect to each other.
