Thermoelectric module (TEM) systems proposed in this study adopts loop thermosyphon with TiO2-nanofluid as working fluid. The present experimental study is focused on the optSubscrSubscript textipt textimum operating condition of the TE system proposed to improve energy output and to obtain stable power generation to be used in future hybrid vehicles. The results of the present study indicate a possibility to use such loop thermosyphon TEMs for future thermoelectric hybrid automotive vehicles. The system showed the optimum performance with acetone with 50% charged amount as the working fluid for the TLT. The system with the new working fluid, nanofluids, neither improved its performance nor its stability.

Abstract. Besides the material property and dimensional optimization of the thermoelectric module, temperature distribution uniformity on the hot junction of the module surface highly affects the outputs of the thermoelectric power generation system. This paper reports the findings on the effects of non-uniform input temperature distribution on the performance of thermoelectric power generation system. To assure the investigation, heat transfer model and finite element formulation of thermoelectric module having non-linear material property have been developed. In addition to the experimental data from a real thermoelectric device, thermoelectric power generation system modeling and simulation using finite element packaging ANSYS software was carried out. For the simulation, temperature dependent thermoelectric material properties such as the Seebeck coefficient, thermal and electrical conductivity have been considered. The experimental and simulation results indicate that keeping the temperature distribution uniform on the hot junction of the thermoelectric module results higher efficiency, higher power, voltage and current outputs than the non-uniform temperature distribution.
