HYDRAULIC COUPLING AND THERMOELECTRIC DEVICE INTENDED, IN PARTICULAR, FOR GENERATING AN ELECTRIC CURRENT IN A MOTOR VEHICLE, INCLUDING SUCH A HYDRAULIC COUPLING

摘要

The present invention relates to a hydraulic coupling for a thermoelectric device comprising a plurality of thermoelectric modules (2), each thermoelectric module (2) including at least one plurality of cylindrical thermoelectric elements (7p, 7n) comprising a central circular recess receiving a central tube (11), a first fluid being intended for circulating through the central tube (11) and a second fluid being intended for circulating around the outer periphery, a so-called inner tubular electrode (14) rigidly connected to an inner surface of each thermoelectric element (7p, 7n), a so-called outer tubular electrode (12) rigidly connected to an outer surface of each thermoelectric element (7p, 7n), said coupling including a body (17) provided with means for establishing fluid communication between the outlet of the central tube (11) of a first thermoelectric module (2) and the intake of a central tube (11) of a second thermoelectric module (2) and at least two electrical contact mountings (24) rigidly connected to said body (17).
