Title:
THERMOELECTRIC CONVERSION ELEMENT
Document Type and Number:
Japanese Patent JPS6030187
Kind Code:
A
Abstract:
PURPOSE:To reduce thermal distortions to be generated to respective sintered thermoelectric semiconductors, and to contrive to check generation of a crack at a thermal power generating element by a method wherein a construction to reduce the temperature difference between the part to face to the heating source and the opposite side part thereof of a semiconductors or conductors at heating starting or stopping time is adopted. CONSTITUTION:A sintered P type thermoelectric semiconductor 1 and a sintered N type thermoelectric semiconductor 2 are joined directly nearly in a U-shape, the leg part edges of both the semiconductors are fixed to a fitment 3 according to a heat-resistant adhesive (ceramic adhesive), and moreover a heat-resistant cap 20 manufactured of a heat-resistant alloy is provided as a thermal buffer member as to cover the tip side whereat both the semiconductors are joined, namely the edge part on both the high temperature side to be heated by a flame, and fixed using a heat-resistant adhesive (ceramic adhesive). Accordingly, the temperature difference between the part to face to the heating source and the opposite side part thereof of the sintered thermoelectric semiconductors is reduced owing to provision of the heat-resistant cap 20, thermal distortions to be generated to the respective sintered thermoelectric semiconductors are reduced, and generation of a crack can be checked.
