THERMOELECTRIC CONVERSION MODULE AND PRODUCTION METHOD FOR SAME

WIPO Patent Application WO/2023/248901

A1

This thermoelectric conversion module comprises: a substrate that has a first main surface and a second main surface; a thermoelectric conversion part that is positioned on the first main surface; first and second thermal conduction parts that are positioned on the second main surface; and a thermal insulation member that is positioned on the second main surface. The thermoelectric conversion part has a p-type thermoelectric conversion element and an n-type thermoelectric conversion element. A first end part of the p-type thermoelectric conversion element contacts a first end part of the n-type thermoelectric conversion element. The first thermal conduction part overlaps with a second end part of the p-type thermoelectric conversion element. The second thermal conduction part overlaps with a second end part of the n-type thermoelectric conversion element. The respective thicknesses of the n-type thermoelectric conversion element and the p-type thermoelectric conversion element are 3-30 μm. The difference in linear expansion coefficient between the first thermal conduction part and the thermal insulation member, and the difference in linear expansion coefficient between the second thermal conduction part and the thermal insulation member are each not more than 100 ppm/K.
