THERMOELECTRIC CONVERSION MODULE AND ITS MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a thermoelectric conversion module which has high reliability and conversion efficiency without generating a stress to a breakdown of a thermoelectric element with an electrode structure in which dense and excellent electric conductivity with much smaller air gap than that of a prior art, which can be easily increased in size and which can be efficiently manufactured. SOLUTION: The thermoelectric conversion module 10 comprises an insulating formwork 11 including a plurality of through holes 12 and a plurality of grooves 13 for electrodes for coupling between the plurality of through holes 12, p-type thermoelectric elements 14 and n-type thermoelectric elements 15 alternately arranged in the holes 12, flame spraying electrodes embedded in the grooves 13 for alternately electrically connecting in series the elements 14 and 15. The flame spraying electrodes are formed of aluminum flame spraying electrodes 17, and a nickel aluminum flame spraying layer 16 is provided as a substrate layer of the flame spraying electrodes.
