Modeling, Experimental Study on the Heat Transfer Characteristics of Thermoelectric Generator

引用

Journal of Thermal Science 2013年第1期22卷 48-54页

作者： Ze-Guang Zhou dong-sheng zhu Hong-Xia Wu Hong-sheng Zhang School of Chemistry and Chemical Engineering South China University of Technology

This paper investigates the heat transfer characteristics of a thermoelectric generator. The influence of heat dissipation intensity to the sub-thermal resistances distribution is experimentally studied. Based on the thermal network analysis and finite time thermodynamics, an analytical model including all thermal resistances (in both thermocouples and external heat exchangers) is developed to predict the performance of the generator. The results show that the computed values of output power agree well with the experimental values. The heat transfer enhancement on the generator cold side greatly reduces the cold side temperature and thermal resistance, and obviously improves the output power. Compare with air natural convection cooling, the main thermal resistance changes from the resistance between the fins and the ambient to the thermal contact resistances between the generator and the heat sink at the conditions of forced convection and water cooling. This study may be guide the optimization of generator structure.

中国有色金属学会会刊：英文版 2004年第Z1期14卷 446-450页

作者： XIE dong-bai zhu sheng-long WANG Fu-hui State Key Laboratory for Corrosion and Protection Institute of Metal Research Chinese Academy of Science Shenyang 110016 China State Key Laboratory for Corrosion and Protection Institute of Metal Research Chinese Academy of Science Shenyang 110016 China State Key Laboratory for Corrosion and Protection Institute of Metal Research Chinese Academy of Science Shenyang 110016 China

The oxidation behavior of Ni-Cr-Al-Y coating produced by multi-arc ion plating with and without an enamel coating was investigated in flow oxygen and oxygen containing water vapor at 900 ℃. The results show that Ni-Cr-Al-Y coating exhibits low oxidation rate at 900 ℃ in pure oxygen and the oxidation kinetics follow the parabolic rate law. The presence of water vapor accelerates the oxidation rate of Ni-Cr-Al-Y coating and K38G *** enamel top coating is very effective in protecting the Ni-Cr-Al-Y coating from water vapor corrosion attack, but the corrosion attack beneath the enamel coating is not observed.
