THERMOELECTRIC MODULE AND METHOD OF ITS OPERATION Russian patent published in 2017 - IPC H01L35/28 

FIELD: electricity.

SUBSTANCE: thermoelectric module (1) has the first wall (2) and the second wall (3) opposite it, as well as elements (4) of thermoelectric material (5) located between them, which are electrically conductively interconnected, fill material (6) by means of which all elements (4) are spaced apart from each other. The material of the first wall (2) and/or the second wall (3) is matched to the thermoelectric material (5) and/or the fill material (6) with respect to thermal expansion, thermal conductivity and strength, such that when the thermoelectric module (1) is operated, at least in the temperature range of 50 to 600°C on the hot side, the compressive stress (11) affecting the elements (4) in the main heat flow direction (8) does not exceed at least the first limit voltage (34), above which the lateral compression of the used thermoelectric material (5) begins or does not exceed at least the second maximum limit voltage (35), above which the plastic deformation of the used thermoelectric material (5) begins.

EFFECT: improved efficiency and service life.
