Abstract

The solar energy collecting mirror deflects energy on black surface. The glass arrangement is designed to prevent build up of thermal stresses. A horseshoe shaped absorption tube coil has sharp curve opposite the mirror. This pointed curve forms the tip of the open end in the horsehoe profile. The expansion of the tube due to the internal pressure is compensated by straps. The connectors of the absorber coil are passed through flexible closing pieces. This absorption coil is held by spacing spiders or by wire holders.

Description

rTeue Form einer Glas - Vakuum - KollektorröhrerNew form of a glass vacuum collector tube

IJm bei röhrenförmigen Absorptionsröhren möglichst alle Sonnens-'rahlen auffangen zu können, müssen bei den bekanntn Konstruktionen die schwarzen Flächen möglichst nahe an die echten Spiegel gebracht wei-den.In the case of tubular absorption tubes, if possible all solar rays In the known constructions, the black areas must be able to catch brought as close as possible to the real mirror.

TTm diesen achtil abzuändern, wird erfindungsgemäß vorgeschlaufen, dem Absorptionskörper eine quasi hufeisenförmigen Ouerschnitt zu geben, der leicht aus einem röhrenförmigen Ouerschnitt zu erstellen ist, und nach unten in der Röhre dem echten Spiegel eine spitze Aufwölbung der =Hufeisenöffnung gegenüber gelegen dadurch zu geben, daß eine entsprechend geformte Fläche in die konkave Krümmung eingeklebt wirdt evtlO kann das auch ein aufgebrachtes Glasteil sein. Sollte diese Fläche aus Kunststoff gefertigt sein, muß dieser etl.To change this eighth, according to the invention, the procedure is to give the absorption body a quasi horseshoe-shaped cross-section that is easy from a tubular cross-section, and down into the tube the real mirror has a pointed bulge opposite the = horseshoe opening by giving that a suitably shaped surface into the concave curvature glued in may also be an applied glass part. Should this Surface made of plastic, this must etl.

von schwarzer Farbe sein.be black in color.

Weiter wird vorgeschlagen, die Ein- und Aus-führungen der Absorptionsschlange nicht direkt in das Glas einzuschmelzen, sondern auf einem längeren Stück durch ein hitzebeständiges, gummielastisches Formstück gegen den Glaskörner abzudichten, um Verspannungen von dem Glaskörper fernzuhalten.It is also proposed that the inlets and outlets of the absorption coil not to melt directly into the glass, but through a longer piece to seal a heat-resistant, rubber-elastic molded piece against the glass grain, to keep tension away from the vitreous body.

Außerdem sollten um das Rohr mit dem HufeisenQuerschnitt besonders an den Ausffihrungen Eisenbänder in gewissen Abständen angeschweißt worden sein, um ein Aufbiegen des Hufeisenquerschnitts durch einen hohen Innendrucks zu verhindern, Vorgeschlagen wird besonders eine Verbindung der beiden Hufeisenschenkel in der der Vertiefung, so daß es keine Probleme mit der spitzen Aufwölbung des echten Spiegels gibto Das hufeisenförmige Profil des Rohres kann evtl. erst nach der Verbiegung zur Schlange angebracht werden, um eine Verquetschung des Ouerschnittes zu vermeiden, und zwar durch leicht gezahnte, selbstangetriebene ProfilrädernAlso, especially around the pipe with the horseshoe cross-section iron strips have been welded to the execution at certain intervals, to prevent the horseshoe cross-section from bending up due to high internal pressure, A connection of the two horseshoe legs in the the recess so that there are no problems with the pointed bulge of the real mirror gabo The horseshoe-shaped profile of the pipe can possibly only after the bending be attached to the snake to avoid squeezing the cross section, through lightly toothed, self-propelled profile wheels
