Experimental study and optimization on thermoelectric generator combined with heat pipe-heat sink

Thermo-Electric Generator (TEG) is presently the most pursued thermal energy harvesting technology from waste heat. In spite of that, TEG devices have been used only on a small scale, because of their low conversion efficiency. Heat sink lack of design is one reason that negatively affects the perfo...
