Abstract:
A cooling unit, comprising:a thermoelectric conversion device in which p-type thermoelectric material elements and n-type thermoelectric material elements are interposed between first and second opposed substrates, and the p-type thermoelectric material elements and the n-type thermoelectric material elements are connected as p-n junctions through an electrically conductive material disposed on the substrates;a temperature sensor integrated in the first substrate and formed on a surface thereof on which the thermoelectric material elements made of thermally conductive material are disposed and interposed between the first and second substrates;an electrically conductive material connecting an electrode of the temperature sensor and an electrode formed on the second substrate opposed to the first substrate on which the temperature sensor is formed for taking the input/output of the temperature sensor; anda control circuit for controlling a current applied to the thermoelectric conversion device in accordance with the output of the temperature sensor.
