Abstract
Description
Beschreibung der Erfindung.Description of the invention.
Die bisher besten bekannten Sonnenkollektorensysteme arbeiten mit metalldotierten Flüßigkeiten als Wärmeträger. Diese haben folgende Nachteile: Frostempfindlichkeit, hoher technischer Aufwand, Verlust an Flüßigkeit, schwierige Handhabung, Notwendigkeit zweier Kreisläufe mit Umwolzpumpen, Wartungsintensität.The best known solar collector systems to date work with us metal-doped liquids as heat carriers. These have the following disadvantages: sensitivity to frost, high technical effort, loss of liquid, difficult handling, necessity two circuits with circulation pumps, maintenance intensity.
Die Erfindung betrifft ein Sonnenlichtkollektorsystem. Der Erfindung liegt die Aufgabe zugrunde, die Nutzung des Sonnenlichts zu verbessern. Die Leistung wird erhöht und die entstandene Wärme wird besser und wirtschaftlicher abgeleitet, als bei herkömmlichen bisher auf dem Markt befindlichen Kollektoren.The invention relates to a solar collector system. The invention is based on the task of improving the use of sunlight. The performance is increased and the resulting heat is dissipated better and more economically, than with conventional collectors previously on the market.
Auf eine Unterlage aus Metall, vorzugsweise Aluminium oder Kupfer wird gemöss der Erfindung eine Schicht bestehend aus einer schwarzen anorgsinischen Masse und einem Bindemittel festhaftend und ohne Zutrittmöglichkeit für Atmorphäririen, die eine Loslösung der Schicht von der Unterlage bewirken können, aufgetragen.On a base made of metal, preferably aluminum or copper According to the invention, a layer consisting of a black inorganic Mass and a binding agent firmly adhering and without access to atmospheres, which can cause the layer to detach from the base.
Die Schicht soll eine Dicke von 0,1 bis 5 cm, vorzugsweise 0,7 bis 1,3 mm haben.The layer should have a thickness of 0.1 to 5 cm, preferably 0.7 to 1.3 mm.
Die Mischung besteht aus 0,2 bis 50, vorzugsweise 1 zu 10 Gewichtsteilen anorganischer Masse zu Bindemittel. Die anorganische Masse besteht vorzugsweise aus Aktivkohle, Ruß, Graphit oder einer anderen Kohlenstoffmasse als Pulver mit einer Korngröße zwischen 10 und 100 Mikron, wobei die mittlere Korngröße größer als 40 Mikron sein soll. Das Bindemittel ist ein in einem Lösungsmittel, vorzugsweise Wasser, gelöstes Polymeres; als am besten geeignet haben sich Stärke, Stärkeclerivate, Dextrine und wasserlösliche synthetische Polymere erwiesen, aber auch Kautschuk und Kautschukähnliche Massen in Emulsion oder Dispersion. Die Menge des Lösungsmittels ist an sich beliebig, da dieses nach dem Auftragen sich durch Verdunsten verflüchtet. Die aufzutragende Masse sollte jedoch eine solche Konsistenz aufweisen, dass sie beospielsweise mit dem Pinsel noch gut verstreichbar oder über eine Pistole versprUhbor ist, andererseits aber auch in einem Auftrogsgang eine Schichtdicke nach dem Trocknen von etwa einem Millimeter ergibt. Dem Bindemittel könen weitere Zusatzstoffe in minderen, jedoch effektiven Konzentrationen beigegeben sein, wie z.B. Korrosionsinhibitoren, Haftvermittler, Antioxidationsmittel, Klebstoffe, Verdickungsmittel u.a..The mixture consists of 0.2 to 50, preferably 1 to 10 parts by weight inorganic mass to binder. The inorganic mass is preferably composed made of activated carbon, carbon black, graphite or another carbon mass as a powder with a grain size between 10 and 100 microns, the mean grain size being larger than should be 40 microns. The binder is one in a solvent, preferably Water, dissolved polymer; starch, starch derivatives, Dextrins and water-soluble synthetic polymers have been shown, but also rubber and rubber-like compositions in emulsion or dispersion. The amount of solvent is arbitrary, as it evaporates after application. However, the mass to be applied should have such a consistency that it For example, it can still be easily spread with a brush or sprayed with a gun is, on the other hand, one layer thickness after drying in one application of about one millimeter results. Other additives can be added to the binder lower, but effective concentrations, such as corrosion inhibitors, Adhesion promoters, antioxidants, adhesives, thickeners, etc.
Verdunstung und Trocknung erfolgen vorzugsweise an der Luft, d.h. ohne zusotzliche Behandlung. Je nach Dicke der Schicht ist die Platte nach ca. einer halben bis fünf Stunden einsatzbereit. Sie wird alsdann in einen Ublichen Kollektorrahmen eingebaut und in üblicher Weise systemgerecht angeschlossen: Der Kollektor wird mit einer Aluminiumplatte versehen, auf welcher der fest aufgebracht worden ist (anstrichartig). Zwischen miteinander versiegelten Doppelglasscheiben entsteht ein Luftraum, welcher von einem Röhrensystem durchzogen ist, in welchem das Wärmetranssportmittel fließt, wobei die Wärme der erhitzten Luft direkt an einen Wärmeträger gegeben wird. Versuche ergaben Meßzahlen von 40 - 50 Grad C. bei bedecktem und von 130 Grad C. bei Sonnenhimmel, die Werte sind im Großraum Frankfurt/Main gemessenEvaporation and drying are preferably carried out in air, i.e. without additional treatment. Depending on the thickness of the layer, the plate is after approx ready for use for half to five hours. It is then placed in a standard collector frame installed and connected in the usual way in accordance with the system: The collector is with an aluminum plate on which the has been firmly applied (paint-like). An air space is created between sealed double glass panes, which is traversed by a pipe system in which the heat transfer medium flows, whereby the heat of the heated air is given directly to a heat transfer medium. try resulted in measurements of 40 - 50 degrees C. when the sky is overcast and 130 degrees C. when the sky is sunny, the values are measured in the greater Frankfurt / Main area
