EXHAUST GAS COOLER

摘要

The invention relates to an exhaust gas cooler (1) for an internal combustion engine, in particular in a motor vehicle, comprising a tube bundle (3) through which exhaust gas (2) or coolant flows. At least two inserts (5) for increasing the heat transfer are provided in at least one of the tubes (4), said inserts being arranged so as to be axially offset with respect to each other and rotated with respect to each other. In particular, a particle deposit that reduces the efficiency of the exhaust gas cooler (1) can thereby be prevented.
