To minimize the radiation energy absorbed by the glass plate, a thin glass plate is provided, the plate thickness of which is below the glass thickness required for a self-supporting glass plate.

Description

Die Erfindung bezieht sich auf einen Reflektor für Sonnenkollektoren mit einer einseitig verspiegelten Glasplatte.The invention relates to a reflector for solar collectors with a glass plate mirrored on one side.

Die Güte eines derartigen Reflektors hängt von der Verspiegelung, der Flächengeometrie sowie von der lichtdurchlässigen Schicht, nämlich der Glasdicke ab. Die Flächengeometrie hat insbesondere einen großen Einfluß bei konkaven Reflektoren, die zur Bündelung der auf ihnen einfallenden Strahlen.dienen.The quality of such a reflector depends on the mirroring, the surface geometry and the translucent layer, namely the glass thickness. The surface geometry has a particular influence on concave reflectors, which are used to concentrate the rays incident on them.

Zum Schutz der Reflektionsfläche und zur Erzeugung einer entsprechend glatten Oberfläche befindet sich die Verspiegelung in üblicher Weise an der Rückseite der Glasplatte. Dadurch entstehen Energieverluste durch Absorption, weil die Strahlung die Glasscheibe zweimal durchqueren muß. Der Erfindung liegt die Aufgabe zugrunde einen Reflektor der eingangs genannten Art dahingehend zu verbessern, daß die Energieverluste gegenüber den herkömmlichen Reflektoren verringert werden.To protect the reflection surface and to create a correspondingly smooth surface, the mirroring is in the usual way on the back of the glass plate. This results in energy losses through absorption, because the radiation has to cross the glass pane twice. The invention has for its object to improve a reflector of the type mentioned in such a way that the energy losses compared to the conventional reflectors are reduced.

Die Aufgabe ist erfindungsgemäß dadurch gelöst, daß eine verspiegelte Glasplatte vorgesehen ist, bei der die Plattendicke unterhalb der für eine selbsttragende Glasplatte erforderlichen Dicke liegt, und daß die Glasplatte mit ihrer verspiegelten Seite auf einen Stützkörper aufgeklebt ist.The object is achieved in that a mirrored glass plate is provided in which the plate thickness is below the thickness required for a self-supporting glass plate, and that the glass plate is glued with its mirrored side to a support body.

Hierdurch ist ein selbsttragender Reflektor erreicht, der nur eine dünne Glasschicht aufweist, durch die die einfallenden und reflektierenden Strahlen hindurch müssen. Die Energieabsorption durch die Glasplatte wird somit verringert. Insbesondere bei gebogenen Reflektoren hat die erfindungsgemäße Ausführung den weiteren Vorteil, daß die Formgebung des Reflektors leichter und genauer hergestellt werden kann. Zylinderartige Formen lassen sich leicht durch Kaltverformung einbringen, wobei durch eine sorgfältig bearbeitete Auflagefläche des Stützkörpers ein Reflektor mit hoher Genauigkeit in der Flächengeometrie hergestellt werden kann.This results in a self-supporting reflector which has only a thin glass layer through which the incident and reflecting rays must pass. The energy absorption by the glass plate is thus reduced. In particular in the case of curved reflectors, the design according to the invention has the further advantage that the shape of the reflector can be produced more easily and more precisely. Cylinder-like shapes can be easily introduced by cold working, and a reflector can be produced with high accuracy in the surface geometry by means of a carefully machined support surface of the support body.

Um bei der Aufbringung der Glasplatte auf den Stützkörper Beschädigungen der Verspiegelung zu vermeiden, ist gemäß einer weiteren Ausgestaltung der Erfindung eine Folie vorgesehen, die zwischen der Glasplatte und dem Stützkörper eingeklebt ist. Die Zwischenfolie hat den weiteren Vorteil, daß auf der einen Seite ein für die Verspiegelung geeigneter Klebstoff verwendet werden kann und auf der anderen Seite ein anderer für die Verbindung mit dem Stützkörper geeigneter Klebstoff genommen werden kann.In order to avoid damage to the mirroring when the glass plate is applied to the support body, a film is provided according to a further embodiment of the invention, which is glued between the glass plate and the support body. The intermediate film has the further advantage that an adhesive suitable for mirroring can be used on one side and another adhesive suitable for connection to the support body can be used on the other side.

Kollektoren werden in der Regel in einer Vielzahl zu einer Kollektoranlage zusammengefaßt. Zu diesem Zweck werden die Kollektoren nebeneinander mit einem Traggestell verbunden und miteinander verschaltet. Im Fall der Parabolsonnenkollektoren werden die Reflektoren und die dazugehörigen Absorber als getrennte Bauelemente mit dem Traggerüst verbunden. Für derartige Fälle sieht die Erfindung vor, daß an den Reflektoren Befestigungsmittel vorgesehen sind, die mit Abstand von der Glasplatte am Stützkörper angebracht sind. Hierdurch wird eine verformungsarme Aufhängung des Reflektors erreicht, bei der Dehnungen und Spannungen der Verbindungsstellen nicht auf den Reflektor geleitet sondern vom Stützkörper aufgenommen werden. Um diesen Effekt zu verstärken können aus dem Stützkörper herausgearbeitete Laschen oder am Stützkörper angebrachte elastische Elemente, wie z.B. Gummiblöcke zur Anbringung der Befestigungsmittel vorgesehen werden.Collectors are usually combined in a large number to form a collector system. For this purpose, the collectors are connected next to each other with a support frame and connected together. In the case of parabolic solar collectors, the reflectors and the associated absorbers are connected to the supporting structure as separate components. For such cases, the invention provides that fasteners are provided on the reflectors, which are attached to the support body at a distance from the glass plate. This results in a low-deformation suspension of the reflector, in which strains and stresses of the connection points are not passed onto the reflector but are absorbed by the support body. In order to intensify this effect, tabs worked out of the support body or elastic elements attached to the support body, such as e.g. Rubber blocks are provided for attaching the fasteners.

Vorteilhaft ist es, wenn der Stützkörper im wesentlichen aus einer Auflageplatte und daran befestigten Versteifungslamellen besteht. Hierdurch sind im Gewicht leichte Konstruktionen von Reflektoren möglich, die außerdem beispielsweise aus dünnen Aluminiumblechen hergestellt sein können, um dem Reflektor ein minimales Gewicht zu verleihen. Der Stützkörper kann aber auch aus einem Kunststoff oder Schaumkörper hergestellt sein.It is advantageous if the support body consists essentially of a support plate and stiffening slats attached to it. As a result, lightweight constructions of reflectors are possible, which can also be made of thin aluminum sheets, for example, in order to give the reflector a minimal weight. The support body can also be made of a plastic or foam body.

In der Zeichnung sind Ausführungsbeispiele der Erfindung schematisch dargestellt. In Fig. 1 ist ein Parobolreflektor 10 zerlegt und im Schnitt dargestellt. Der Reflektor besteht aus einer Glasplatte 11 einer Folie 12 und einem Tragkörper 13. Die Glasplatte 11 ist auf einer Seite mit einer Verspiegelungsschicht 14 versehen, die mit einem Lacküberzug 15 zum Schutze der Verspiegelung abgedeckt wird.Exemplary embodiments of the invention are shown schematically in the drawing. In Fig. 1 a Parobol reflector 10 is disassembled and shown in section. The reflector consists of a glass plate 11, a film 12 and a Support body 13. The glass plate 11 is provided on one side with a reflective layer 14, which is covered with a lacquer coating 15 to protect the reflective coating.

Der dünne Spiegel 11, 14, 15 wird über eine Form 16 gebogen. Danach wird die Folie 12 auf die verspiegelte Seite aufgeklebt. Durch geeignete Wahl der Folienstärke kann ein optimales Verhältnis von Zug zu Schubspannung, die beim Biegen auftreten, eingestellt werden. Die Folie kann aus Metall und/oder Glasfaser bestehen. Anschließend wird der Stützkörper 13 mit vorgefertigter gebogener Auflagefläche 17 auf die Folie 12 geklebt. Es ist aber auch möglich, bei geeigneter Werkstoffwahl die Folie 12 wegzulassen.The thin mirror 11, 14, 15 is bent over a mold 16. Then the film 12 is glued to the mirrored side. By an appropriate choice of the film thickness, an optimal ratio of tension to shear stress, which occurs during bending, can be set. The film can consist of metal and / or glass fiber. Then the support body 13 is glued to the film 12 with a prefabricated curved support surface 17. However, it is also possible, with a suitable choice of material, to omit the film 12.

Der Stützkörper 13 besteht aus einer Auflageplatte 18, die durch eine wabenartige Versteifung 20 und eine Grundplatte 19 in ihrer Form gehalten und verstärkt wird. Die Versteifung 20 kann auch aus Lamellen oder zickzackartig gebogene Fläche gebildet sein.The support body 13 consists of a support plate 18, which is held and reinforced in shape by a honeycomb-like reinforcement 20 and a base plate 19. The stiffening 20 can also be formed from lamellae or a zigzag curved surface.

Durch entsprechende Werkstoffwahl und Dimensionierung kann erreicht werden, daß der Reflektor 10 leicht im Gewicht und flach im Aufbau ist und trotzdem die notwendige Festigkeit und Steifigkeit hat, die der Glasspiegel alleine nicht aufbringen würde.By appropriate choice of material and dimensioning can be achieved that the reflector 10 is light in weight and flat in construction and still has the necessary strength and rigidity that the glass mirror alone would not bring.

In Fig. 2 ist ein Reflektor mit einem aus dickem Blech bestehenden Stützkörper 22 gezeigt, auf dem ein Spiegelglas 23 aufgeklebt ist. Für die Befestigung des Reflektors an ein Traggerüst 24 sind Gummiblöcke oder aus elastischem Kunststoff bestehende Blöcke 25 oder metallischer Federbleche auf die Rückseite des Stützkörpers 22 aufgeklebt. Diese Blöcke dienen zur elastischen Halterung von Befestigungselementen 26, die aus einer mit dem Block festverbundenen Schraube 27 und einem Mutterpaar 28 bestehen.In Fig. 2, a reflector is shown with a support body 22 made of thick sheet metal, on which a mirror glass 23 is glued. For attaching the reflector rubber blocks or blocks 25 made of elastic plastic or metallic spring plates are glued to the back of the support body 22 on a support frame 24. These blocks are used for the elastic mounting of fasteners 26, which consist of a screw 27 firmly connected to the block and a pair of nuts 28.

Eine weitere Variante der Befestigungsmöglichkeit ist in Fig. 3 gezeigt. Ein verstärkter Stützkörper 30, der Art wie der Stützkörper 13 aus Fig. 1, ist zwischen der Abdeckplatte 31 und der Grundplatte 32 an der Verbindungstelle mit einem Gießharz ausgefüllt. In diesem Harz wird ein Gewindeeinsatz eingegossen oder ein Befestigungsbolzen 33 zur Befestigung des Reflektors an eine Halterung 34 eingeschraubt. Zur Unterstützung dient eine zweiteilige Schraubvorrichtung 35, die miteinander verschraubt werden können und von der ein Teil am Stützkörper 30 und das andere Teil an der Halterung 34 befestigt ist. Die Schraubverbindung 35 dient zur Justierung des Abstandes zwischen dem Tragkörper 30 und der Halterung 34 und übernimmt außerdem die Stützlast des Reflektors.Another variant of the fastening option is shown in FIG. 3. A reinforced support body 30, of the type like the support body 13 from FIG. 1, is filled with a casting resin between the cover plate 31 and the base plate 32 at the connection point. A thread insert is cast into this resin or a fastening bolt 33 is screwed into a holder 34 for fastening the reflector. A two-part screw device 35 is used for support, which can be screwed together and one part of which is fastened to the support body 30 and the other part to the holder 34. The screw connection 35 is used to adjust the distance between the support body 30 and the holder 34 and also assumes the vertical load of the reflector.

Die Halterung 34 kann entweder direkt das Traggerüst oder ein Zwischenelement, wie es in Fig. 4 gezeigt ist, sein. Die Halterung 34 gemäß Fig. 4 wird an vier Punkten mit dem Reflektor bzw. dem Stützkörper in einer der bereits beschriebenen Art oder ähnlichen Weise verbunden, wozu drei oder vier Verbindungsstellen 35 vorgesehen sind. Der Ab-stand zwischen diesen Befestigungspunkten ist so ausgelegt, daß die durch einen Wind auftretende Beanspruchung auf ein Minimum reduziert wird. Eine an die Halterung 34 angeklebte oder angeschweißte Platte 37 dient mit zur Befestigung der Halterung 34 an das Traggerüst 38. Anstelle einer getrennten Platte 37 kann auch eine herausgeformte Lasche vorgesehen sein. Diese Konstruktion ermöglicht eine flexible Aufhängung des Reflektors, so daß der Reflektor auch bei durch Wind hervorgerufenen Bewegungen kaum Spannungen oder Verformungen erfährt.The holder 34 can either be directly the supporting structure or an intermediate element, as shown in FIG. 4. 4 is connected at four points to the reflector or the support body in a manner or similar to that already described, for which purpose three or four connection points 35 are provided. The A b-stand between these attachment points is designed so that the stress caused by a wind on Minimum is reduced. A plate 37 glued or welded to the holder 34 also serves to fasten the holder 34 to the supporting structure 38. Instead of a separate plate 37, a tab which is formed out can also be provided. This construction enables flexible mounting of the reflector, so that the reflector hardly experiences any tension or deformation, even in the case of movements caused by wind.
