Abstract

The sealing is for use with a vacuum solar collector consisting of two panels, the front one being of transparent material, esp. glass. A gas-tight seal is achieved by using a metal foil, or an elastic formed component with rounded angular profile. The foil is pressed into the glass during manufacture, or by subsequent application of a glass bead. The foil is welded or soldered to the lower metal panel.

Description

Gasdichter Vakuum - SonnenkollektorGas-tight vacuum solar collector

Ein Problem bei der Erstellung von flächigen Vakuumkollektoren, wie sie zOn 1 der B 26 23 86SoO beschrieben werden, ist die gasdichte Verbindung der vorderen mit der hinteren Scheibe,wobei die vordere aus einem durchsichtigen Material wie Glas bestehen muß T)a elastische Klebungen Gas in das Vakuum hineinlassen und unelastische Verbindungen Spannungsprobleme ergeben, muß eine Lösung gefunden werden.A problem with the creation of flat vacuum collectors, such as they are described at 1 of the B 26 23 86SoO, is the gas-tight connection of the front with the rear disc, the front being made of a transparent material like glass, T) a elastic bond must let gas into the vacuum and Inelastic connections result in tension problems, a solution must be found.

So wird erfindungsgemäß vorgeschlagen, die Abdichtungder beiden Scheiben - s.a. P 26 do 758o9 - durch eine tetall- oder Glasfolie zu bewerkstelligen, die die Elastizität ermöglicht und gleichzeitig gasdicht ist. Dazu muß der Kollektor gerundete Ecken besitzen, wenn nicht rund sein, Die Abdichtung zu den oberen ( Glas-) Scheiben kann dadurch geschehen, daß di- Folie beim Pressen der Scheiben mit hineingearbeitet wurde und zwar an den Rändern oder daß die Folie auf die schon fertige Scheibe mit einem einem aufgelegten Glaswulst angebradht wird, wobei natürlich die ganze Scheibe nochmals zu temperieren ist. Die untere Scheibe z.B. aus einem Metallformkörper sollte gegen die Folie durch Schweißen oder töten abgedichtet werden. Die Folie kann natürlich auch durch einen elastischen Formkörper mit gerundetem Winkelprofil ersetzt werden Wenn die Folie an die untere Scheibe geschweißt wird, muß die Glasscheibe gekühlt werden, ebenso die Metallscheibe.Thus, according to the invention, it is proposed that the two panes be sealed - see also P 26 do 758o9 - to be achieved by a metallic or glass film, the allows elasticity and is gas-tight at the same time. The collector must do this have rounded corners, if not round, the seal to the upper (glass) Slices can be done by incorporating di-film into them when pressing the slices was and that at the edges or that the film on the already finished disc with a glass bead placed on it, whereby of course the whole pane is to be tempered again. The lower disk, for example, made of a metal molding should be sealed against the foil by welding or killing. The foil can of course also by an elastic molded body with a rounded angle profile If the foil is welded to the lower pane, the glass pane must be replaced be cooled, as well as the metal disc.

Die Metallfolie kann dann am fertigen Kollektor durch eine Kunststoff - Folie oder Schaum gegen Beschädigungen geschüttz werden, Zuerst wird also die Folie an der Oberen Scheibe angebracht, dann die .Scheibe mit einer selektiven Schicht versehen und dann die Folie an de# nach hinten abgebogenen Rändern der hinteren Metallscheibe angeschweißt0The metal foil can then be protected against damage by a plastic foil or foam on the finished collector, so first the foil is attached to the upper pane, then the pane is provided with a selective layer and then the foil is attached to the top pane. to the rear bent edges of the rear metal disc welded on0

Patentansprüche: 1. Eine Abdichtung eines Vakuum - Flächen - Sonnenkolektors dadurch gekennzeichnet, daß die Abdichtung durch eine Metallfolie bzw. Formkörper mit Winkelprofil(aber rund) bewerkstelligt wird. Claims: 1. A seal for a vacuum surface solar panel characterized in that the seal is made by a metal foil or molded body is accomplished with an angle profile (but round). 2.Das die Abdichtung der Folie gegen Glas durch einpressen bei der Herstellung oder durch nachträgliche Auflegung eines Glaswulstes über einen eil der Folie erreicht wird0 Evtl. reicht aber schon das Ankleben mit einem unelastischen Kleber.2. The sealing of the film against glass by pressing in at the Manufacture or by subsequent application of a glass bead over a part the film is reached0 but it may be enough to stick on with an inelastic Glue. 3.Das die Abdichtung der Folie gegen Metall durch Schweißen oder töten vorgenommen wird.3. That the sealing of the foil against metal by welding or killing is made.
