SOLAR COLLECTOR ASSEMBLY WITH PARABOLIC REFLECTOR AND REFLECTOR HOLDER, METHOD FOR MANUFACTURING THE SOLAR
COLLECTOR ASSEMBLY AND USE OF THE SOLAR COLLECTOR ASSEMBLY
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to a solar collector assembly, a method for manufacturing the solar collector assembly and a use of the solar collector assembly. 2. Description of the Related Art
A solar field is a modular distributed system of solar col¬ lector assemblies (SCA) connected to each other via a system of pipes.
Each SCA is an independent unit for collection and for trans¬ fer of energy, with its own power to rotate and to communicate within an electronic network.
The SCA is a linear parabolic focusing collector with one di- mensional (usually East-West) tracking system. Solar radia¬ tion is focused onto a heat collection element consisting of a hollow tube through which a heat transfer fluid is circulated . The solar field comprises loops, which are for instance as¬ sembled from two SCAs . Each SCA comprises for instance 8 pa¬ rabola segments.
For each of the parabola segments a truss is used. The truss has two main functions: It supports parabolic reflectors of the SCA and it provides an interface to a drive system of the collector .
SUMMARY OF THE INVENTION
It is an object of the invention to provide a solar collector assembly support structure, which is more reliable and sim- plified compared to the state of the art.
Further objects of the invention are a method for manufacturing the solar collector assembly and a use of the solar col¬ lector assembly.
These objects are achieved by the inventions- specified in the claims .
A solar collector assembly is provided with at least one ar- rangement of one parabolic reflector and at least one reflec¬ tor holder for holding the parabolic reflector, wherein the reflector holder is fixed to at least one edge of the para¬ bolic reflector. The holder is fixed averted to a reflecting surface of the parabolic reflector (parabolic mirror) .
Additionally a method for manufacturing the solar collector assembly with following steps is described: a) Providing at least one parabolic reflector and providing at least one re¬ flector holder for holding the parabolic reflector and b) Forming an arrangement of the parabolic reflector and the re¬ flector holder such, that the reflector holder is fixed to at least one edge of the parabolic reflector.
Finally a use of the solar collector assembly in a power plant for converting solar energy into electrical energy is provided .
In an embodiment the reflector holder is fixed to at least one further edge of at least one further parabolic reflector and the parabolic reflector and the further parabolic re¬ flector are arranged side by side such, that a reflecting surface of the parabolic reflector and a further reflecting surface of the further parabolic reflector form an entire re-
fleeting surface and a focal line of the reflecting surface and a further focal line of the further reflecting surface form a contiguous (and straight) entire focal line of the en¬ tire reflecting surface. In contrast to the state of the art each reflector holder holds two adjacent reflectors. By this measure for instance a reflector is fixed on both sides of the reflector (with exception of outer reflectors of a solar collector assembly) . As a result a number of reflector hold¬ ers can be reduced.
At least one support structure for supporting the arrangement and for driving the solar collector assembly is present. In one embodiment the support structure comprises a torque tri¬ angle truss.
Building blocks of the support stricture and triangle truss respectively are e.g. pipes, which are produced with loosened tolerances and are highly stackable during shipment, and junctions/intersections which are used to connect the pipes and the intersections. The triangle truss is built of unique diagonals pipes connected in every intersection. These diago¬ nals pipes enable high torque stiffness of the torque trian¬ gle truss. The arrangement and the support structure, e.g. the torque triangle truss can be connected by different methods, e.g. by welding. But it is advantageous to use clinching. As a result the parabolic reflector and the reflector holder, building blocks of the support structure among themselves and/or the support structure and the arrangement are linked together by at least one clinching connection. For instance a torque triangle truss and the arrangement are linked together by a clinching connection. The linking comprises a clinching mechanism. For a manufacturing of the torque triangle truss a clinching mechanism is used.
By using the clinching it is not necessary, that each of the building blocks (reflector, reflector holder, support struc-
ture, etc) is accurately manufactured. There is an acceptable tolerance (deviation), which is compensated by the clinching. As a result the manufacturing is simplified. Additionally a high optical accuracy during a long operating phase of years is reached.

DETAILED DESCRIPTION OF THE INVENTION The solar collector assembly 1 comprises at least one ar¬ rangement 10 of at least one parabolic reflector 11 and at least one reflector holder 12 for holding the parabolic reflector 11. The solar collector assembly 1 comprises additionally at least one torque triangle truss 20 for supporting the ar¬ rangement 10 and for driving the solar collector assembly 1.
The reflector holder 12 is fixed to at least one edge 111 of the parabolic reflector 11.
Additionally the reflector holder 12 is fixed to at least one further edge 131 of at least one further parabolic reflector
13. The parabolic reflector 11 and the further parabolic re¬ flector 13 are arranged side by side such, that a reflecting surface 112 of the parabolic reflector (11) and a further re¬ flecting surface 132 of the further parabolic reflector 13 form an entire reflecting surface 142 and a focal line 113 of the reflecting surface 112 and a further focal line 133 of the further reflecting surface 132 form a contiguous straight entire focal line 143 of the entire reflecting surface 142. The torque triangle truss 20 and the arrangement 10 with the parabolic reflector 11 and the reflector holder 12 are linked together by a clinching connection 30 (figure 4) .
Single building blocks 21 of the torque triangle truss 20, e.g. diagonal pipes, are connected together by a clinching connection, too.
Within the focal lines 113, 133 and 143 of the reflecting surface 112, the further reflecting surface 132 and the en- tire reflecting surface 142, respectively heat receiver tubes 16 are located. Within these heat receiver tubes 16 a heat transfer fluid is circulating. By the heat receiver tubes solar energy is absorbed and transferred to the heat transfer fluid. By this the solar collector assembly can be used in a power plant for converting solar energy into electrical energy. The collected solar energy is used to generate steam. The steam drives a turbine which is connected to a generator for generating electricity. The solar collector assembly 1 is connected to a drive pylon 15. The complete solar collector assembly comprises a number of parabola segments 16. For each parabola segment a torque triangle truss 20 is used.
