| Abstract: | A model of two stage semiconductor thermoelectric generator was set up with the impact of external heat transfer being taken into account. By using a finite time thermodynamics theory an analysis was conducted of the performance of a two stage semiconductor thermoelectric generator under Newton's heat transfer law. A general relationship between power output and efficiency on the one side and working electrical current on the other was derived. The optimum allocation of heat transfer surface area of a heat exchanger at two sides and the optimum allocation of the number of thermoelectric elements were obtained. The influence of various factors on the performance of the generator was also analyzed. |
