Abstract：This study developed an integral thermoelectric generator system with high-performance heat transfer and thermoelectric conversion function, using the metal pin-fin arrays coupling with the forced convection heat transfer technique to be the heat absor 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. Some critical heat-transfer parameters on the design of the integral thermoelectric generator system were also provided and discussed. Finally, a series of systematical experiments were performed to simulate of systematical experiments were performed to simulate an integral thermoelectric generator system operating at the exhaust pipe. Experimental tests were utilized to investigate the electricity. The relevant variable parameters were (1) the configuration of the heat absorber; (2) the inlet temperature of hot air (Ti=100~350℃); (3) the flow rate of hot air (FH=3~15 m³/hr) and (4) the flow rate of cooling air (Fc=0~366 m³/hr). The experimental results also demonstrated the validity of the proposed theoretical model.
