A parabolic trough collector includes a parabolic mirror support structure with a parabolic mirror surface applied thereto, and an absorber support structure supporting an absorber tube. The parabolic mirror support structure and the absorber support structure are mechanically fastened in a fixed position relative to one another on a torsion tube that is arranged below the parabolic mirror surface, and mounted together with the parabolic mirror surface in a fashion capable of rotation about a parabolic trough collector longitudinal rotation axis. The torsion tube is arranged such that the parabolic trough collector longitudinal rotation axis coincides with the central longitudinal axis of the torsion tube. |
