EXPERIMENTAL STUDY IN GENERATING POWER OF THERMOELECTRIC CONVERSION SYSTEM WITH NOVEL POROUS MEDIUM HEAT ABSORBERS

Name of activity：

Keywords：Thermoelectric conversion，Heat absorbers，Generating power.

Abstract： This project focuses on the establishment of the technology of high-efficient thermoelectric conversion for vehicle engine as well as improving fuel economy and reducing environmental pollution caused by vehicle emissions. Four types of heat absorbers with different structures have been designed and studied through experiment. In the experiment，”Seebeck effect”，which means when there exists temperature gradient between two surfaces of thermoelectric generator(TEG)，thermal energy will be converted into electric power by TEG. Experiment results suggest that stacking brass particles in the heat absorbers do increase the generating power 50~70%，and that model A(square pin-fin) and model B(snake-shape channel) with 4mm-diameter brass particles have the best generating capability. In terms of pressure drop，model A(square pin-fin) is  relatively small. Thus model A(square pin-fin) is the most suitable one for the thermoelectric conversion system. A relevant empirical formula is established revealing the relationship between generating power and the temperature gradient to serve as an important reference for designers and developers in the related vehicle and energy industries.
