THERMOELECTRIC DEVICE AND THERMOELECTRIC MODULE, ESPECIALLY INTENDED TO GENERATE AN ELECTRIC CURRENT IN AN AUTOMOTIVE VEHICLE

摘要

The invention relates to a thermoelectric device (1) comprising at least two thermoelectric elements (3, 4), called first thermoelectric element and second thermoelectric element, able to generate an electric current owing to the action of a temperature gradient exerted between two of their faces, called first and second active faces (5, 6), the said device comprising a first electrical connection means (21) connecting electrically in series the two thermoelectric elements (3, 4) and a second electrical connection means (22) intended to connect electrically in series one of the two thermoelectric elements (3, 4) of the device with a third thermoelectric element (3, 4), joining of the first electrical connection means (21) and the second electrical connection means (22, 42) together with the first and the second thermoelectric elements (3) being obtained by means of sintering of the said first and second thermoelectric elements.;The invention also relates to a thermoelectric module (20) comprising a plurality of the said thermoelectric devices (1) and a method for manufacturing the device and the module.
