Abstract

Thermoelectric module (TEM) is proven to be reliable heat pump and heat engine with numerous applications in space satellites and deep space probes. It is able to convert heat energy to electrical energy directly and vice versa, with no mechanical moving parts. The relatively low conversion efficiency of TEM has been a major factor in restricting their use to specialised situations where reliability is a major consideration. However, with further materials development and the potential to harness energy from waste heat, thermoelectric generator (TEG) sees a new stage in its development. This research aims to to investigate, design and evaluate the performance of TEG from waste heat. A novel theoretical model was developed to obtain the thermal predictions. TE model simulation indicates effective heat transfer at the heat sinks is a vital factor in TE system performance. Preliminary investigation on characterisation shows high precision equipment is required for accurate results.

About the Speaker

Ms Yong Kai Yen graduated from Monash University Sunway Campus with Bachelor of Engineering (Mechanical) in year 2011. She joined Monash University for postgraduate studies in year 2012 under the supervision of A/Prof Ong Kok Seng and Dr. Liben Jiang. Her research area focuses in exploiting thermoelectric for waste heat recovery. The present study aims to determine the thermal characteristics of TE modules and evaluate its performance.
