Thermoelectric conversion module with series connection

摘要

In the conventional thermoelectric conversion module, P-type thermoelectric semiconductor chips and N-type thermoelectric semiconductor chips are alternately arranged in both the longitudinal and the transverse directions. Consequently, assembling work is complicated and there arises the problem in quality that erroneous types of chips are arranged. In the present invention, therefore, each of either rows of chips or columns of chips is constituted by thermoelectric semiconductor chips of the same type, thereby to improve assembling workability as well as to prevent erroneous arrangement. Furthermore, as a preferred fabricating method, bar-shaped thermoelectric semiconductors are used and are jointed to one substrate and then, are electrically disconnected between the leads.
