Definitions

  • the present invention relates to the design of solar collectors and the design of segments of a solar collector.
  • Solar collectors are often used in the form of parabolic-trough concentrators in power plants, or for recovery of process heat.
  • Such large-scale plants can largely consist of a plurality of serially arranged solar collectors with trough-shaped reflectors which will direct the sunlight onto a tubular absorber.
  • trough-shaped reflectors For orienting the solar collectors corresponding to the sunlight, it is known to rotate the trough-shaped reflectors about their longitudinal axis.
  • a plurality of serially arranged reflectors are rotated simultaneously.
  • the trough-shaped reflectors Since, in this manner, constructions having a length of up to 120 m are to be rotated, the trough-shaped reflectors must have a high torsional stiffness so that the deviation of the rotational angle during rotation of the reflectors cannot exceed a mere minimum.
  • Solar collectors of lightweight construction often have the disadvantage that their structure has insufficient self-supporting properties, with the consequence that a large number of supports are required and or that the solar collectors can be only quite small in size.
  • a segment of a solar collector comprises a top side, a bottom side and a circumferential end face having at least one longitudinal side, wherein the longitudinal side forms a top edge with the top side and forms a bottom edge with the bottom side.
  • the segment further comprises a core structure having at least one core made of foamed material.
  • Arranged on the core structure is a shell made of one or a plurality of layers of a fiber material, wherein the shell at least partially covers the top side, the bottom side and at least the longitudinal side of the circumferential end face, and wherein at least one layer of the shell extends about the top edge and at least one layer of the shell extends about the bottom edge.
  • the segment further comprises a reflection layer disposed on the top side.
  • a core structure comprising at least one core of foamed material makes it possible to accomplish a particularly light-weighted design of the segment and thus of a solar collector.
  • the shell comprising one or a plurality of layers of a fiber material has the effect that the segment is given sufficient stability.
  • two adjacent segments can be connected to each other, wherein the shell of a segment that extends about the top edge and the bottom edge in combination with the shell of an adjacent segment that extends about the top edge and the bottom edge, forms a kind of profile carrier shaped as a double T.
  • the shell consists of at least one first shell member made of a fiber material that is arranged on the top side and covers the core structure on the top side, and of a second shell member made of a fiber material that is arranged on the bottom side and covers the core structure on the bottom side.
  • the shell of the core structure can be produced in a simple manner.
  • the first shell member extends around the top edge and/or the second shell member extends around the bottom edge.
  • a segment according to the invention which comprises two or more longitudinal sides of the surrounding end face, via which the segment can be connected to other segments, it can be provided that the shell member extends around the top edges of all longitudinal sides while the second shell member extends around the bottom edges of all longitudinal sides.
  • the shell comprises a third shell member made of a fiber material that is arranged on the at least one longitudinal side and covers the core structure on the longitudinal side, said third shell member extending around the top edge and/or the bottom edge.
  • the first, the second and/or the third shell member can respectively consist of at least one layer of fiber material, preferably of at least two layers of fiber material and with particular preference of three layers of fiber material.
  • the layers of the shell are made of glass-fiber or carbon-fiber material and comprise unidirectional or multi-axial fibers.
  • the desired strengthening effect of the shell can be achieved in an advantageous manner.
  • the segments can be given high resistance to rupture and high torsional stiffness while, at the same time, a solar collector composed of the segments according to the invention can have a particularly advantageous self-supporting structure. This can be accomplished particularly by selecting, for different layers of the shell, materials with different fiber directions, since the fiber direction can be selected corresponding to the respective stress direction of the segments.
  • reinforcement strips of fiber material are arranged around the top edge, the bottom edge and/or around the further edges formed between the surrounding end faces and the top side and the bottom side, so as to reinforce the top edge, the bottom edge and the further edge of the core structure.
  • the core structure comprises at least one rib of a fiber material, preferably of wood, said rib being preferably arranged parallel to the at least one longitudinal side.
  • a rib is effective to increase the stability of the core structure.
  • the core structure consists of two cores of foamed material and of three ribs of fiber material, said ribs and said cores of foamed material being arranged alternately.
  • the core structure consists of two cores of foamed material, which cores are enclosed by two ribs, with a further rib being arranged between the cores of foamed material.
  • the two outer ribs herein are arranged respectively on one of the longitudinal sides. Such a configuration has proven to be particularly advantageous.
  • each rib comprises a cover made of a fiber material, thus allowing for a very high stability of the ribs.
  • a flange is arranged for attachment of the segment to an opposite segment.
  • flanges arranged on the segments for mutual attachment of opposite segments have been found to be of particular advantage.
  • a plurality of segments serially fastened via the longitudinal sides of the segments can be connected, with the aid of the flanges, to a further row of flanges.
  • the flanges are a part of the overall structure of the segment and thus are formed by the core structure and the shell.
  • the top side of the core structure can have a curvature so that the reflection layer on which there is arranged the part of the shell covering the top side of the core layer, is also curved.
  • the segments according to the invention can be assembled to parabolic-trough-shaped or parabolic solar collectors.
  • the layers of the shell, the at least one core of foamed material, the ribs of the core structure, the shell of the ribs, and/or the reinforcing strips can be bonded to each other, preferably by means of an epoxy resin adhesive or another resin-based adhesive such as e.g. polyester or polyvinyl resin.
  • an epoxy resin adhesive has the benefit that this adhesive will become connected in an advantageous manner to the layers of the shell consisting of fiber material, and to the ribs made of fiber material, particularly if the fiber material ribs consist of wood. In this manner, it is advantageously rendered possible for the adhesive to become anchored to the respective material.
  • the material When using glass-fiber or carbon-fiber material for the layers of the shell, the material will advantageously be soaked by the epoxy adhesive, thus generating a structure of epoxy resin and glass fibers or carbon fibers which has a high stability.
  • the use of the epoxy adhesive makes it possible to bond the layers to each other in such a manner that they can nearly be regarded as being one integral piece.
  • the object forming the basis of the invention is further achieved by a solar collector comprising a plurality of segments according to the invention.
  • Such a solar collector can be conveniently produced and be transported to its installation site in that a row of adjacent segments are bonded to each other already at the production site and in situ merely have to be connected to a further row of segments according to the invention.
  • the solar collectors composed of the segments according to the invention are very light-weighted and thus transportable in a convenient manner. Further, the solar collectors have a high torsional stiffness and comprise a self-supporting structure.
  • a U-profile enclosing the flanges.
  • Said U-profile can consist e.g. of a plurality of layers of fiber material which are bonded to each other preferably by an epoxy resin adhesive. It has been found that the use of a U-profile makes it possible to achieve a particularly high torsional stiffness of the solar collector.
  • the solar collector according to the invention can consist of e.g. 24 segments according to the invention.
  • a framework construction is arranged on the surface formed by the bottom side of the segments so as to increase the torsional stiffness, said framework construction being attached to the bottom side of the solar collector preferably via fastening means bonded between two adjacent segments.
  • the framework construction can be connected e.g. to a support structure of an absorber.
  • Another option resides in that the framework construction of the solar collector is preferably connected to an attachment metal plate of a solar collector support. In this manner, it can be safeguarded that a very high stability of the framework construction is achievable.
