Abstract

Abstract: Aiming at the differences among the temperature differences and different characteristics of the thermoelectric devices of an automobile exhaust thermoelectric generator,in order to maximize the power generation potential of each thermoelectric device,the thermoelectric module of the thermoelectric generator was optimized by an topological structure research method,and the serial and parallel problems of the thermoelectric module were abstracted as a mathematical problem based on the graph theory,then the algorithm was targeted designed .The experimental results show that,compared with other simple series or parallel structures, the electrical topology optimized by this method may fully utilize the power generation potentials of each thermoelectric devices under the same conditions and are improved the output powers of the automobile exhaust thermoelectric generators.

Key words: automobile exhaust thermoelectric generator, topological optimization, thermoelectric module, transfer efficiency
