  • a length compensation device 45 which exerts a pulling force on the absorber pipe string 11 by means of a cable pull 47 and a weight 49. It is thereby achieved that, when the absorber strand 11 is elongated, this takes place in a linear direction and bending of the absorber tubing 11 can not occur.
  • parabolic trough collector modules 1 By means of the parabolic trough collector modules 1 according to the invention, it is possible to form collectors of several hundred meters in length, which can be provided in a stable and cost-effective manner, since elaborate connections, such as ball joints, can be dispensed with. As a continuous absorber tubing 11th can be created, in addition, pressure and heat losses can be reduced.
