Title:
THERMOELECTRIC CONVERSION MODULE
Document Type and Number:
WIPO Patent Application WO/2019/225036
Kind Code:
A1
Abstract:
A thermoelectric conversion module (100) is provided with a substrate (10H), a plurality of thermoelectric conversion element pairs (20) that are provided on the substrate and electrically connected in series, a pair of external terminals (40) for inputting or outputting power, and a low-melting point conductor (60), wherein: the low-melting point conductor has a melting point substantially equal to the heat-resistant temperature of p-type thermoelectric conversion elements (21P) or n-type thermoelectric conversion elements (20N); one of the external terminals has a first connection part (42) connected to a p-type thermoelectric conversion element; the other external terminal has a second connection part (43) connected to a n-type thermoelectric conversion element; the first connection part, the second connection part, and the low-melting point conductor are positioned in an inner region (51) of the substrate; at least a part of the low-melting point conductor is positioned between the external terminals; and the low-melting point conductor is electrically insulated from at least one of the external terminals, whereby even when some of a plurality of the thermoelectric conversion modules are damaged due to exposure to high temperature, a heat power generation system can be continuously used.
