Thermoelectric conversion module and thermoelectric conversion module system

A thermoelectric conversion module may include a plurality of n-type thermoelectric conversion elements and a plurality of p-type thermoelectric conversion elements alternating with one another, a plurality of first electrodes and a plurality of second electrodes that alternately connect the plurality of alternating n-type and p-type thermoelectric conversion elements at hot sides and cool sides, and a plurality of case electrodes, each of which selectively connects the first electrodes adjacent to each other, among the plurality of first electrodes. The first electrodes and the case electrodes are configured to be movable relative to each other so that the plurality of first electrodes are electrically connected through the plurality of case electrodes or electrical connections between the plurality of first electrodes through the plurality of case electrodes are disabled according to a relative movement of the plurality of first electrodes and the plurality of case electrodes.
