Title:
A thermoelectrical conversion module and a manufacturing method for the same
Document Type and Number:
Japanese Patent JP6171513
Kind Code:
B2
Abstract:
In a configuration to join thermoelectric elements with an electrode in a thermoelectric module, reduction in junction reliability between the thermoelectric elements and the electrode is suppressed in a high-temperature environment and in an environment in which vibration and shock are imposed as load, to efficiently transmit the outer-circumferential temperature to the thermoelectric elements. In a thermoelectric module in which a plurality of p-type thermoelectric elements and a plurality of n-type thermoelectric element are alternately arranged by aligning the surfaces thereof on the high-temperature side and the surfaces thereof on the low-temperature side, to electrically connect the thermoelectric elements in series to each other; the p-type thermoelectric elements and the n-type thermoelectric element are joined via an intermediate layer with a deformable stress relaxation electrode, to thereby absorb stress taking place during the module assembling process and the module operation by the electrode.
