Characteristic of maximum power with temperature difference for thermoelectric generator

This paper is associated with the manufacture of thermoelectric generator(TEG) and the characteristic of TEG. TEG was consisted of water heater, pump, 32 thermoelectric modules and aluminum, and was flowed by hot and cold water through the aluminum containers. It was found that the electric power was increased with increasing the temperature difference(,6 T) in the range between 20 similar to 50K. The electric efficiency took a maximum values, 1.04% for DeltaT=50K. On the other hand, these electric behaviors could be calculated with the function of temperature difference and the electric current. This simulation may be useful to estimate the capacity of TEG and to develop a thermoelectric generation system which converts unused energy from close-at-hand sources such as garbage incineration heat and industrial exhaust etc. into electricity.
