MULTI-ELEMENT THERMAL CONDUCTOR FOR A VACUUM TUBE OF A SOLAR THERMAL COLLECTOR

Thermal conductor (4) for a vacuum tube (1) of a solar thermal collector (10) having double vacuum tubes, which conductor is intended to be in contact with a heat collector tube (3), and the internal wall of the vacuum tube (1), comprising a heat absorbing element (2), to provide heat transfer from the internal wall of the vacuum tube (1) toward the heat collector tube (3), characterized in that it comprises a first conducting element (4a), comprising a pivot element (P1), a second conducting element (4b), comprising a second connection portion (8b) for connection with the first conducting element (4a), the second connection portion (8b) being mounted with the ability to rotate on the pivot element (P1) of the first conducting element (4a), and an elastic return member (5) in contact with the second conducting element (4b), to cause it to rotate with respect to the first conducting element (4a).
