THERMOELECTRIC CONVERSION DEVICE

摘要

The purpose of the invention is to further increase the amount of power generation by taking in a greater amount of heat on the downstream side in a heating flow path of a heating fluid that imparts a temperature difference to a thermoelectric conversion module. Disclosed is a power generation device 1 comprising: a high-temperature-side sheet part 12 and a low-temperature-side sheet part 22 that are arranged in opposition to one another; a pipeline 10 through which a heating fluid H for heating the high-temperature-side sheet part 12 passes; a thermoelectric conversion module 40 that is disposed between the sheet parts 12, 22 and to which a temperature difference is imparted; and a fin 70 that is provided in the pipeline 10, and that gathers the heat of the heating fluid H and conveys the heat to the high-temperature-side sheet part 12. The fin 70 includes a rear extending part 75 that extends from a downstream-side end part of the pipeline 10 toward an exit 10b side of the pipeline 10 in a region where the thermoelectric conversion module 40 is disposed, and the rear extending part 75 takes in the downstream-side heat of the heating fluid H.
