Abstract
A parabolic trough collector module with an absorber tube with a central axis; a parabolic reflector which focuses solar radiation onto the absorber tube and which includes a reflector surface; and a stand device, on which the parabolic reflector is pivotally mounted, the stand device having at least one stand post and the absorber tube being mounted on the stand post. In the reflector surface, the parabolic reflector has a cut-out section running perpendicularly to the longitudinal direction, and a support device extends through the cut-out section and has an absorber tube mount that forms a linear guide, on which mount the absorber tube is slidingly mounted in the longitudinal direction.

A parabolic trough collector module, comprising:
- an absorber tube having a central axis, a parabolic reflector which focuses solar radiation onto the absorber tube and which comprises a reflector surface, and a stand device, on which the parabolic reflector is pivotally mounted, the stand device having at least one stand post and the absorber tube being mounted on the stand post,
- wherein in the reflector surface the parabolic reflector has a recess running transversely to the longitudinal direction, a support device extending through the recess and having an absorber tube mount that forms a linear guide, on which mount the absorber tube is mounted for displacement in a longitudinal direction,
- wherein a support structure comprising two supporting struts arranged transversely to the central axis of the absorber tube and via which the parabolic reflector is mounted on the stand device, wherein the supporting struts are respectively arranged on an end face of the parabolic reflector,
- wherein the support device supports a part of the weight of the absorber tube independently of the parabolic reflector and the stand device.
