MULTI-ELEMENT THERMAL CONDUCTOR FOR VACUUM TUBE OF A THERMAL SOLAR SENSOR WITH DUAL VACUUM TUBES

摘要

The main object of the invention is a thermal conductor (4) for vacuum tube (1) of a solar thermal collector (10) with double vacuum tubes, intended to be in contact with a heat collecting tube (3). ) and the inner wall of the vacuum tube (1), comprising a heat-absorbing element (2), for thermal transfer from the inner wall of the vacuum tube (1) to the heat-collecting tube (3), characterized in that it comprises a first conductive element (4a), comprising a pivot element (P1), a second conductive element (4b), comprising a second connection portion (8b) with the first conductive element (4a), the second connecting piece (8b) being rotatably mounted on the pivot element (P1) of the first conductive element (4a), and an elastic return member (5) in contact with the second conductive element (4b), for rotating it relative to the first conductive element (4a).
