Abstract

Thermoelectric technology is one of the greatest inventions in the field of green technology.It is because thermoelectric technology capable to convert heat energy directly into electrical energy without required external conversion circuit.Also,thermoelectric technology is eco-friendly and it does not emit any polluted substances or gases in its application.There is the only issue that facing by the thermoelectric technology which is its low power generation.Nowadays,applications that use this type of technology are less and limited due to its low power generation.With its low efficiency of power generation, thermoelectric technology is only capable to supply power to low power electronic devices and some niche applications.Therefore,an analysis project is proposed to provide an engineering solution which capable to enhance the efficiency of thermoelectric technology in terms of temperature gradient and output voltage generated.In this paper,an analysis is carried out to analyse the behaviour of thermoelectric module under several arrangements of thermoelectric module.Also,a tested is carried out by using different types of heat sinks in terms of sizes for thermoelectric module to analyse the effect corresponding to its output voltage.It is important to study the relationship between temperature gradient and output voltage of thermoelectric module in order to come out an alternative solution to improve its efficiency of power generation.In the summary of the analysis results, thermally connected in parallel and electrically connected in series (TPES) configuration showing the best results in terms of temperature gradient and output voltage.Heat sink with large contact surface and high height design shows the best cooling performance because it capable to maintain a huge temperature gradient between both sides of thermoelectric module.
