    Abstract: A thermoelectric power generation system includes a first flow path, along which a first fluid flows, a second flow path, along which a second fluid having a lower temperature than the first fluid flows, a thermoelectric module arranged between the first flow path and the second flow path, and a controller that switches between a power generation mode and a heating mode. In the power generation mode, the thermoelectric module is caused to generate electric power, based on a difference between a temperature of the first fluid and a temperature of the second fluid. In the heating mode, a first surface of the thermoelectric module is heated using the Peltier effect caused by supplying electric power to the thermoelectric module. A distance between the first surface and the first flow path is shorter than a distance between the first surface and the second flow path.

    Abstract: A thermoelectric conversion unit includes a pair of low-temperature fluid flow path sections arranged to face each other, a high-temperature fluid flow path section arranged between the pair of low-temperature fluid flow path sections, a pair of thermoelectric modules each arranged between the high-temperature fluid flow path section and one of the pair of low-temperature fluid flow path sections in a one-to-one relation, and a rod-shaped convex fin and concave fin both arranged in the high-temperature fluid flow path section. The concave fin includes a recess fitted to the convex fin. An outer peripheral surface of the convex fin and an inner peripheral surface of the recess of the concave fin are in contact with each other, and a gap is formed between a tip of the convex fin and a bottom of the recess of the concave fin.

    Abstract: The present disclosure provides a thermoelectric conversion module that enables continued use of a thermoelectric generation system even when a part of a plurality of the thermoelectric conversion modules fails by being exposed to a higher temperature. The thermoelectric conversion module according to the present disclosure includes a substrate, a plurality of thermoelectric conversion element pairs electrically connected in series on the substrate, a pair of external terminals that carries out one of inputting and outputting of electric power, and a low melting point conductor. The low melting point conductor has a melting point that is substantially equal to a heat-resistant temperature of a p-type thermoelectric conversion element or an n-type thermoelectric conversion element. One of the pair of external terminals has a first connecting part connecting with the p-type thermoelectric conversion element positioned at one end of the plurality of thermoelectric conversion element pairs, whereas the other of the pair of external terminals has a second connecting part connecting with the n-type thermoelectric conversion element positioned at the other end of the plurality of thermoelectric conversion element pairs. The first and second connecting parts and the low melting point conductor are positioned in an inner region of the substrate. At least a part of the low melting point conductor is positioned between the pair of external terminals and is electrically insulated from at least one of the pair of external terminals.
