Abstract
Claims
1. A thermoelectric conversion device comprising: a Peltier element having a first substrate including one or more first electrodes; a second substrate facing the first substrate and including one or more second electrodes; one or more P-type semiconductor elements and N-type semiconductor elements alternately arranged between one surface of the first substrate and the second substrate, with their ends joined in series by the first electrodes and the second electrodes; and a first metal layer provided on the other surface of the first substrate; and a first temperature sensor provided between the first metal layer and the first substrate.
2. A thermoelectric conversion device according to claim 1, wherein the first temperature sensor is in contact with the first metal layer.
3. A thermoelectric conversion device according to claim 1, wherein the first substrate has a recess for housing the first temperature sensor.
4. A thermoelectric conversion device according to claim 1, wherein the first substrate is a flexible substrate.
5. A thermoelectric conversion device according to claim 4, wherein the flexible substrate includes a polyimide film.
6. A thermoelectric conversion device according to claim 1, wherein the first substrate is a ceramic substrate.
7. A thermoelectric conversion device according to claim 6, wherein the ceramic substrate comprises aluminum nitride or alumina.
8. A thermoelectric conversion device according to claim 1, wherein the Peltier element further comprises a second metal layer provided on the other surface of the second substrate, and a second temperature sensor provided between the second metal layer and the second substrate.
9. A thermoelectric conversion device according to claim 1, wherein the first temperature sensor is a thermistor element or a semiconductor temperature sensor.
10. A thermoelectric conversion device according to claim 1, wherein the Peltier element further comprises a heat insulating resin provided between the P-type semiconductor element and the N-type semiconductor element.
