THERMOELECTRIC MODULE, IN PARTICULAR INTENDED TO GENERATE AN ELECTRIC CURRENT IN A MOTOR VEHICLE

摘要

The present invention relates to a thermoelectric module (20) including at least one thermoelectric element (3) including at least one opening (10) formed to have a thermal relation with a high temperature fluid. The thermoelectric element (3) includes an active surface formed to have a thermal relation with a low temperature fluid of which temperature is lower than the temperature of the high temperature fluid. The thermoelectric fluid (3) is designed to generate a current under the performance of a thermal gradient provided by the high and low temperature fluids between the opening (10) and the active surface of the thermoelectric element. The opening (10) includes two circuits (41,42) to circulate the high temperature fluid, which are called a first circuit (41) and a second circuit (42). The first circuit (41) touches the thermoelectric element (3) and the second circuit (42) is positioned inside the first circuit (41).
