摘要： A thermoelectric generation unit according to the present disclosure includes a plurality of thermoelectric generation tubes. Each tube has a flow path defined by its inner peripheral surface, and generates an electromotive force in an axial direction based on a temperature difference between its inner peripheral surface and outer peripheral surface. The thermoelectric generation unit includes a container housing the tubes inside, and a plurality of electrically conductive members providing electrical interconnection for the tubes. The container includes a shell surrounding the tubes and a pair of plates being fixed to the shell and having a plurality of openings, with channels being formed so as to house the electrically conductive members and interconnect at least two of the openings. The respective ends of the tubes are inserted in the openings of the plates. The tubes are connected electrically in series by the electrically conductive members housed in the channels.

摘要： A plurality of first cup-shaped members and a plurality of second cup-shaped members are placed alternately in repetition to form a pipe having an inner through-hole. At this point, neither the first cup-shaped members nor the second cup-shaped members are sintered yet. Then, the resultant pipe is sintered to obtain a pipe-shaped thermal power generation device. While the pipe is sintered, a pressure is applied to the pipe along a longitudinal direction of the pipe in a direction in which the pipe is compressed.

摘要： An exemplary thermoelectric generator disclosed herein includes: a first electrode and a second electrode opposing each other; and a stacked body having a first end face and a second end face. The stacked body is structured so that first layers made of a first material and second layers made of a second material are alternately stacked, the first material containing a metal and particles having a lower thermal conductivity than that of the metal, the particles being dispersed in the metal, and the second material having a higher Seebeck coefficient and a lower thermal conductivity than those of the first material. Planes of stacking between the first layers and the second layers are inclined with respect to a direction in which the first electrode and the second electrode oppose each other.
