摘要 |
The invention relates to a member for transferring solar energy by a heat transfer fluid. It comprises an assembly of three tubes, the first being introduced into the hollow part of cross-section (SV) of a collector envelope, the second providing the upstream connection of the general circuit to the said member, comprising a straight portion which penetrates the first tube and a flattened portion which is to be engaged with the flattened portion of a third tube which, downstream, connects said member to the general fluid circulation circuit. The first tube is sealed by means of a hollow connecting plug and the cross-sections (S1) and (S2), respectively of the first and second tubes are selected in such a way that (S1-S2) is substantially equal to (S2), the cross-section (S1) being itself close to the cross-section (SV) of the hollow part of the envelope.
