Abstract: An exemplary thermoelectric generator unit according to the present disclosure includes a plurality of tubular thermoelectric generators. Each generator generates electromotive force in an axial direction based on a difference in temperature between its inner and outer peripheral surfaces. The unit further includes a container housing the generators inside and a plurality of electrically conductive members providing electrical interconnection among the generators. The container has fluid inlet and outlet ports through which a fluid flows inside the container, and a plurality of openings into which the respective generators are inserted. In one implementation, the unit includes a baffle, which is provided between the fluid inlet port and the generators and changes the flow direction of the fluid that has flowed into the container through the fluid inlet port.
