Title:
THERMOELECTRIC CONVERSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/176832
Kind Code:
A1
Abstract:
This thermoelectric conversion device comprises: a first thermoelectric layer 12a and a second thermoelectric layer 12b that have mutually opposite conductivity types and that are provided alternately in a first direction which runs parallel to the surfaces of the first thermoelectric layer and the second thermoelectric layer; a first connecting layer 14a and a second connecting layer 14b that are provided alternately in the first direction and between the first thermoelectric layer and the second thermoelectric layer so as to be electrically and thermally connected to the first and second thermoelectric layers; a first thermally conductive layer 16a that is thermally connected to the first connecting layer and that extends in a second direction intersecting the surface thereof; a first insulating layer 17a through which the first thermally conductive layer penetrates and which has a smaller thermal conductivity than that of the first thermally conductive layer; and a second insulating layer 17b through which the first thermally conductive layer penetrates, which has a smaller thermal conductivity than that of the first insulating layer, and which is provided between the first insulating layer and the first and second thermoelectric layers. The second insulating layer 17b has a thickness greater than or equal to 1/4 of the larger of the following distances: the distance between the edge on the first thermoelectric layer side of the first thermally conductive layer, and the center of the second connecting layer in the first direction; and the distance between the edge on the second thermoelectric layer side of the first thermally conductive layer, and the center of the second connecting layer in the first direction.
