Abstract
Official abstract text for this publication.
A heat exchanger ( 7 ) for an exhaust system ( 5 ) of an internal combustion engine ( 1 ), includes a heating tube ( 16 ) for carrying hot exhaust gas and a cooling tube ( 17 ) for carrying a liquid cooling agent. A thermoelectric generator ( 13 ) generates an electric voltage from a temperature difference and is arranged with the adjacent tubes in a stacking direction ( 18 ) to form a stack ( 21 ). A support tube ( 28 ) is supported in the stacking direction on wall sections ( 29 ) of the respective tube ( 16, 17 ), which wall sections mutually face each other, and is arranged in the respective heating tube ( 16 ) and/or cooling tube ( 17 ). Increased energy efficiency is achieved if at least two support tubes ( 28 ), which differ from one another by tube length and/or tube end ( 30 ) and/or by tube cross sections, are arranged in the respective tube ( 16, 17 ) at right angles to a longitudinal direction ( 31 ).
