Abstract: The global energy and environmental issues are promoting the development ofinnovative energy solutions. Thermoelectric Generators (TEGs) are regarded as apromising alternative to conventional energy technologies. TEG is a device thatconverts thermal energy directly into electric power by exploiting Seebeck effect. Inthe present study, dynamic performance characteristics of a TEG are experimentallystudied under different operating conditions. The effect of input heat rate and theinfluence of utilizing extended surfaces (fins) on both transient and steady stateperformance of a TEG are experimentally investigated. The variation in thetemperature of the TEG hot and cold sides in addition to the output voltage is takenas a denotation of the performance characteristics. Input heat rate of 15.0 W, 17.5 W,20.0 W, 22.0W and 25.0 W are applied to the TEG hot side. Free air convection (FC)is the utilized for heat dissipation from the TEG module through the cold side. Fromthe experimentation, it can be deduced that increasing the input heat rate provideshigher temperature difference across the module sides leading to higher poweroutput. Additionally, using fins to aid heat dissipations enhanced the TEGperformance by lowering the temperature of cold side and increasing the temperaturedifference across the module. The experimental data obtained are compared with thedata available by the TEG module manufacturer and excellent agreement isobtained.
