In this study several heat exchanger designs were constructed, tested, and the effect of the design on the overall efficiency and power generated by thermoelectric generators was measured. The thermoelectric elements were attached to the heat exchanger and hot gas passed through the system simulating automotive exhaust. An aluminum duct heat exchanger, a copper heat exchanger, and a heat exchanger with a twisted tape insertion were tested. The heat exchangers were all rectangular with similar dimensions and minimum thicknesses near the wall. The flow of exhaust gas was created by heated air flow ranging from 100-150 LPM. The cool side …
