Title:
THERMOELECTRIC CONVERSION ELEMENT AND PRODUCTION METHOD FOR SAME
Document Type and Number:
WIPO Patent Application WO/2021/085040
Kind Code:
A1
Abstract:
[Problem] To obtain high thermal electromotive voltage with a simple structure in a thermoelectric conversion element in which the directions of magnetization, temperature gradient, and electromotive force are orthogonal to each other. [Solution] This thermoelectric conversion element 1 is provided with: a tape-like member 10 that comprises an insulation film and a thermoelectric material layer which is formed on the surface thereof and in which the directions of magnetization, temperature gradient, and electromotive force are oriented perpendicular to each other; and a pair of terminal electrodes E1, E2 that are connected to the thermoelectric material layer at different positions in the longitudinal direction thereof. The tape-like member 10 is wound in a coil so as to have the longitudinal direction thereof oriented in the circumferential direction. The thermoelectric material layer is magnetized in the radial direction. Thus, since the tape-like thermoelectric material layer is magnetized in the radial direction and wound in the circumferential direction, it is possible to generate thermal electromotive voltage in accordance with the temperature gradient in the axial direction. Furthermore, since the direction of electromotive force lies in the circumferential direction, it is possible to make the tape-like member in a simple structure.
