Exhaust gas guidance device for an internal combustion machine with a thermoelectric generator

摘要

The exhaust gas guiding device has a thermoelectric generator (17) with multiple thermoelectric modules, which are arranged between a surface (18) and another surface (21). The modules are provided with thermoelectric material with different charge carrier densities in the flow direction of the exhaust gas. The former surface is configured such that a convective heat transfer resistance between the exhaust gas and the former surface is reduced. An independent claim is also included for a method for manufacturing a thermoelectric generator.
