| Summary: | Thermoelectric
generators are long-life electricity generators that operate according to the
Seebeck thermoelectric effect and produce DC voltage by utilizing the
temperature difference on hot and cold surfaces, without moving parts. The
ability to generate electricity directly in any situation where the temperature
difference between the surfaces of the thermoelectric modules arises makes it
possible to generate electricity from the first time in the exhaust systems of
the internal combustion engines. It is very important to examine the recovery
of the thermoelectric generators in the heating process in the internal
combustion engines due to the reduced generator efficiency at low revs. In this
study, thermoelectric generators were used to provide exhaust heat recovery in
heating process of an internal combustion gasoline engine, electrical gains
obtained at three different temperature averages were investigated and
experimental and simulated results were compared. A maximum ΔT = 165 °C
temperature difference was obtained between the module surfaces. In the
experiments performed, ΔT = 165 °C, RL = 10 Ω load resistance, maximum 6.75 V
voltage, 0.65 A current is obtained. Experimental and simulation results are
generally in coherence. |
