This study developed an integral thermoelectric generator system with high-performance heat transfer and thermoelectric conversion functions, using the metal pin-fin array coupling with the forced convection heat transfer technique to be the heat absorber and heat sink. A one-dimensional steady heat conduction model with internal Joule heat generation and Seebeck effect was proposed to predict the power generation performance of the present thermoelectric system including the heat absorber and heat sink at various operation conditions. Critical heat-transfer parameters on the design of the integral thermoelectric generator system were derived and discussed. Finally, a series of systematical experiments were performed to simulate an integral thermoelectric generator system operating at the exhaust pipe. The experimental results also demonstrated the validity of the proposed theoretical model.
