Suppression of heat leakage by cooling thermoelectric device for low-temperature waste-heat thermoelectric generation

The output voltage characteristics of a thermoelectric generator were analyzed to suppress heat leakage for low-temperature waste-heat thermoelectric generation. The experimental results show that the pre-cooled thermoelectric device output a higher voltage than the reference device. The experimental results also show that the influence of heat leakage took a longer time to appear using the pre-cooled thermoelectric device. These results suggest that the pre-cooled thermoelectric device is effective in suppressing the influence of heat leakage.
