Parabolic trough collector for use in solar thermal plant to e.g. collect solar radiation in long prismatic mirror surface, has pivot point that lies on side of mirror surface, where side is turned towards absorber tube
The collector has an absorber tube (7) and a torsion tube, which run parallel together and are arranged at a distance from sides of a mirror surface (3). The mirror surface and the absorber tube are attached to the torsion tube. The collector is rotatably supported, and a pivot point of the collector lies on a side of the mirror surface, where the side is turned towards the absorber tube. A flange (17) is provided at an end of torsion tube segments (13.1-13.4) to connect the two segments. The pivot point lies at a middle point of the torsion tube. An independent claim is also included for a method for mounting a parabolic trough collector.
