Abstract

Solar rays concentrating mirrors are made of glass, sheets and/or foils of plastic material, by bending two thin planar elements over a shaped matrix and by bonding them together by an adhesive. When glass is used, the top element can be silvered at the back or two plain elements can carry a third thin reflecting glass or plastic layer. This reduces the cost of mfr. for thick curved solar mirrors and increases the mfg. precision, e.g. for cylindrical parabolic mirrors.

Description

BXSELCHNI1NG: Konzntri erender Seh ichten-Solarsi iegelBXSELCHNI1NG: Concentrating sight solar seal

BESCHREIBUNG: Konzentrierende, deutlich gewölbte Solarspiegel werden z.Zt. als warmverformte Dickglasspiegel, pneumatisch-elastische Kunststoff-Folien Spiegel oder als z.B. Honecomb-Sandwich Spiegel hergestellt.DESCRIPTION: Concentrating, clearly curved solar mirrors become currently as thermoformed thick glass mirrors, pneumatic-elastic plastic films Mirror or manufactured as a Honecomb sandwich mirror, for example.

Alle die Verfahren weisen Probleme mit relativ hohen Herstellungskosten und herstellungsbedingten Ungenauigkeiten auf die, die Höhe der Spielkonzentratiwi z,B. bei Zylinderparabol-Spiegeln stark einschränken.All of the methods have problems with relatively high manufacturing costs and manufacturing-related inaccuracies on the, the amount of Spielzentratiwi z, B. with cylindrical parabolic mirrors.

Erfindungsgemäss sollen diese Probleme umgangen werden, indem eben vorgefertigte relativ weiche Spiegelplatten CFig.la) über eine entsprechende Form gewölbt:werden und in dieser Form mit einer zweiten relativ weichen und verformbaren Platte verklebt werden (Fig.1 b). Da dann diese 2 verklebten Platten zusammen z.B. die doppelte Dicke aufweisen, erhöht sich ihre Steifigkeit auf das 8-fache, so dass ein selbsttragender, weitgehend in der vorgegebenen gewölbten und konzentrierenden Form, verbleibender Spiegel entsteht(Fig.l c> Nach der Verklebung wollen beide Platten zwar elastisch zurückfedern, weiden aber durch die stark erhöhte Steifigkeit des dickeren Plattenverbundes daran weitgehend gehindert.According to the invention, these problems are to be circumvented by precisely prefabricated relatively soft mirror plates CFig.la) have a corresponding shape arched: are and in this shape with a second relatively soft and deformable Plate are glued (Fig. 1 b). Since then these 2 glued plates together e.g. have twice the thickness, their rigidity increases to 8 times, so that a self-supporting, largely arched and concentrating in the given Shape, remaining mirror is created (Fig. 1 c> After gluing, both want Plates spring back elastically, but graze due to the greatly increased rigidity the thicker composite panels largely prevented from doing so.

Es verbleibt eine restliche Zugspannung in der unteren und eine entsprechende Druckspannung in der oberen Platte, während die Klebeschicht eine entsprechende Scherspannung übernimmt.There remains a residual tensile stress in the lower one and a corresponding one Compressive stress in the top plate, while the adhesive layer has a corresponding Takes over shear stress.

Die genannte Anordnung kann erfindungsgemäss auch auf 3 oder mehr Schichten angewandt werden. Z.B. kann eine wesentliche Variante auch durch 2 nichtspiegelnde verklebte Platten und eine zusätzliche verhältnismässig dünne Spiegelglas- oder Spiegelfolien-Schicht gebildet werden.According to the invention, said arrangement can also be set to 3 or more Layers are applied. E.g. an essential variant can also be made up of 2 non-reflective glued plates and an additional relatively thin mirror glass or Mirror film layer are formed.

Der vorgenannte schichtförmige Aufbau von Spiegelkonzentratoren kann erfindungsgemäss für zunächst ebene Platten. gelten, die vor dem Verkleben entweder nur elastisch oder nur plastisch oder teilweise elastisch und tei]weise plastisch verformt werden.The aforementioned layered structure of mirror concentrators can according to the invention for initially flat plates. are valid, the before Gluing either only elastic or only plastic or partially elastic and partially plastically deformed.

Auch gelten die vorgenannten Merkmale sowohl für zylinderparabolförmige als auch für vollparabolförmige Spiegel.The aforementioned features also apply to cylinder parabolic shapes as well as for fully parabolic mirrors.
