Claims16
A thermoelectric module comprising:
- a first substrate having a first surface;
- a second substrate having a second surface facing the first surface of the first substrate, the second surface being apart from the first surface by a certain distance;
- a plurality of thermoelectric elements arranged on the first surface and the second surface;
- a temperature detector on the first surface of the first substrate;
- and
- a thermal transfer layer which is on the second surface of the second substrate and faces the temperature detector, the thermal transfer layer having a thermal conductivity higher than that of the second substrate;
- a plurality of electrodes arranged on the first surface or the second surface and electrically connected to at least one of the plurality of thermoelectric elements, the thermal transfer layer being constituted as one of the plurality of electrodes,
- wherein the thermal transfer layer has a T-shaped configuration including an electrode part which is connected to at least one of the plurality of thermoelectric elements and directly interfaces the thermoelectric elements;
- and an extended part which is other than the electrode part and faces the temperature detector and does not interface the thermoelectric elements;
- wherein a length of the electrode part is longer than that of the extended part in a longitudinal direction of the thermal transfer layer.
