Kitte, F. Beck, D. Jänsch] Dimensioning a thermoelectric generator for vehicle applications poses major challenges. Besides the fundamental process of determining the layout, an optimization procedure is necessary to harness the maximum potential from a thermoelectric system under given boundary conditions. The thermal boundary conditions encountered in this application are not constant. In this context, a multichannel thermogenerator shows benefits by distributing individual mass flows in relation to the operating point maximizing power output across the entire range of operating points. The innovative approach underlying the continuous thermogenerator model supports the process of global optimization. The parameters to be optimized are configured as dimensionless variables. The model not only guarantees very short computation times but also maintains high quality. The optimization method is presented in detail using an example of searching for an optimum material layout, variable fin geometry, and variable leg height across and along the direction of gas flow. The materials or material combinations to be analyzed are lead and bismuth telluride. The heat exchanger has a reference geometry. The article describes the combination of dimensionless optimization parameters that provides the greatest increase in thermoelectric power output compared with the basic concept. The discussion concludes with a cost-benefit analysis of the measures chosen.
