Abstract

A louvre-type solar collector comprises a number of inclined blades through which a piping system containing the heat-transporting fluid passes, the blades being welded in the pipe. At the inner edge, i.e., the edge removed from the incident sunlight, each blade is curved towards its neighbour thus virtually closing the gap between them and forming a pocket in which the solar energy is trapped.

Description

Beschreibung der Erfindung eines Jalousie-AbsorbersDescription of the invention of a blind absorber

für Sonnenkollektoren zur Nutzung der Sonnenenergie Die Erfindung betrifft einen Absorber mit Jalousieartiger, einstellbarer Vergrößerunr der Ahsorbtionsfläche durch spezifisch festgelegte Bleche aus unterschiedlichen Werkstoffen.for solar collectors to use solar energy The invention relates to an absorber with louvre-like, adjustable enlargement of the absorption area through specifically defined sheets made of different materials.

Das Wärmeübertragungsmedium fließt durch ein diinnwandizes Röhrensystem aus Kupfer,Messing oder Stahl,daß mit dünnen Blechstreifen jalousieartig bestückt und weich verlötet wird.Die Blechstreifen können aus Aluminium,Stahl oder anderen Werstoffen sein und die verschiedensten Formen haben.The heat transfer medium flows through a thin-walled tube system made of copper, brass or steel, that fitted with thin sheet metal strips like a blind and is soft soldered. The sheet metal strips can be made of aluminum, steel or other Be materials and have the most varied of forms.

Dicse Konstruktion ist die günstigste Lösung zur Erreichung optimaler Wärmer übertragungswerte,da abgesehen vom Glas alle Reflektionen im Jalousiesystem abgefangen werden.This construction is the cheapest solution to achieve optimal Warmer transmission values, since apart from the glass all reflections in the blind system be intercepted.

(siehe Skizze 1) Dic Formgebung der verwendeten Jalousie-Bleche muß nach Thermaltechnischen-Gesichtspunkten in Bezug auf die jeweilige Dachneigung,Sonneneinstrahlwinkel und Standrichtung des Hauses ausgelegt und angepasst werden.(see sketch 1) The shaping of the blind sheets used must be According to thermal engineering aspects in relation to the respective roof pitch, angle of sunlight and orientation of the house can be designed and adjusted.

Bekannt sind Absorber aus Flachband,Rollband oder flachen Blechen bei denen die Flächen der Absorber mit Kanälen durchzogen sind.Durch Farbauftrag oder Chemischeschichten werden die Absorber gegen Reflektion geschützt.Absorbers made of flat strip, roller strip or flat metal sheets are known in which the surfaces of the absorber are criss-crossed with channels or chemical layers, the absorbers are protected against reflection.

Die Verbesserung durch die vorliegende Erfindung bezieht sich auf die jalout sieartig angeordneten Bleche mit den als Strahlenfalle abgebogenen Blechen.The improvement by the present invention relates to the jalout-like arranged sheets with the sheets bent as a beam trap.

(siehe Skizze 2 ) Die Strahlenfalle ist dadurch gekennzeichnet,daß das der Eintrittsöffnung gegenüber liegende Ende der Jalousiebleche abgebogen und mit eine. Radius versehen ist.(see sketch 2) The radiation trap is characterized in that the end of the louvre plate opposite the inlet opening is bent and with one. Radius is provided.

Die Strahleneintrittsöffnung ist demzufolge nach unten geschlossen und die eingefallene Sonnenenergie wird innerhalb der Jclousiebleche verarbeitet.The beam entry opening is therefore closed at the bottom and the solar energy that has fallen in is processed within the junction sheet.

Erfindungsgemäß wird das dadurch erreicht,daß die auf das Röhrensystem auf= gelöteten Jalousiehleche die einfallenden Sonnenstrahlen auffangen und durch die Strahlenfalle so lange in sich reflektieren das keine Riickstrahlung erfolgen kann.Die Blechstreifen leiten die entstandenen Erhitzungen über das Röhrensystem an die Übertragungsflüssigkeit weiter.According to the invention this is achieved in that the on the tube system on = soldered venetian blind catch the incident sun rays and pass them through the radiation trap reflect in itself so long that no back radiation occurs The metal strips conduct the heat generated through the tube system to the transmission fluid.

Die Erfindung läßt die verschiedensten Verwendungsmöglichkeiten und Ausführungsmöglichkeiten in Sonnenkollektoren zu.The invention has a wide variety of uses and Execution options in solar panels too.

Ein Beispiel ftir den Eibau des Jalousieabsorhers in einen Sonnenkollektor ist in Ahbildung 3 gerieben.An example for the construction of the blind absorber in a solar collector is rubbed in Figure 3.

Der dargestellte Sonnenkollektor besteht im wesentlichen aus einer PVC lsolierplatte die eine Wärmeabstrahlung nach unten hin verhindern sell.The solar collector shown consists essentially of one PVC insulation panels that prevent heat from being radiated downwards.

Aus einer Seitenisolation und Auflage für den Jalousieahsorber.Einem temperaturbeständigem Kunststoffteil als Distanzstück und einer Glas-Deckscheibe, Gehalten werden die Teile durch einen zweiteiligen Stablrahmen wohei der ohere Rahmen mittels Federzug und Schnellverschliissen das System zusammen hält.From a side insulation and a support for the blindsorber temperature-resistant plastic part as a spacer and a glass cover plate, The parts are held in place by a two-part bar frame, where the upper frame is Holds the system together by means of a spring balancer and quick release.

Der Anschluß des Kollektors und des Absorbers erfolgt an ein Flüssigkeits= system mittels Rohren und Robrkupplungen.The collector and the absorber are connected to a liquid = system using pipes and couplings.

In den Sammelbehältern der Jalousieahsorher befinden sich mehrere Trenn= leithleche die der Kühlflüssigkeit die Zwangsrichtung im Verlauf der Erwärmung vorgeben.There are several in the collecting containers of the blinds handlers Separation = Leithleche which of the cooling liquid the forced direction in the course of the heating pretend.
