Abstract

The present invention relates to a heat transfer device, more preferably for an exhaust system of a combustion engine, preferentially of a motor vehicle, with at least one warm tube for conducting a fluid emitting heat, with at least one cold tube for conducting a fluid absorbing heat and with at least one thermoelectric generator for generating electric energy from a temperature difference, wherein a thermoelectric generator each is arranged between a warm tube and a cold tube.The efficiency of the heat transfer device is improved if the respective thermoelectric generator is in contact with the respective tube via a heat conducting material and if the respective heat conducting material is configured as shaped body.
