  • Publication number: 20180287036
    Abstract: A thermoelectric power generation device includes a plurality of units that are stacked, each unit including a thermoelectric module containing at least one thermoelectric element, and a first plate and a second plate interposing the thermoelectric module therebetween, wherein a spacer is interposed between a surface of one of the first plates facing away from the corresponding thermoelectric module and a surface of the opposing second plate facing away from the corresponding thermoelectric module, the spacer contacting the first plate and the second plate and defining a fluid passage jointly with the first plate and the second plate, and wherein the fluid passages defined between the adjacent units are configured to receive supply of high temperature fluid and low temperature fluid in an alternating manner in a stacking direction of the units. The plates can be conformed to the thermoelectric module, and the stiffness of the plate can be increased.

  • Publication number: 20180033941
    Abstract: A power generation system that has an increased power generation efficiency and can be substituted for a conventional heat exchanging system is provided. A power generation system 1 comprises a power generation module 2 provided with one or more thermoelectric elements 7A, 7B; a heat exchanger 3; a high-temperature fluid passage 4 including a high-temperature fluid inlet 4A and a high-temperature fluid outlet 4B, the high-temperature fluid passage being connected to the power generation module and the heat exchanger both located between the high-temperature fluid inlet and the high-temperature fluid outlet; and a low-temperature fluid passage 5 including a low-temperature fluid inlet 5A and a low-temperature fluid outlet 5B, the low-temperature fluid passage being connected to the power generation module and the heat exchanger both located between the low-temperature fluid inlet and the low-temperature fluid outlet.
