Description
aehbedeckungsplatte zur Umwandlung üblicher Dachbedeckungen ^ — roof cover plate for converting common roof coverings ^ -
in Sonnen-Kollektorenin solar collectors
Es sind Mittel bekannt, durch welche die üblichen Dachbedeckungen zu Sonnen-Kollektoren umgewandelt werden. So ist vorgeschlagen, die Bedeckungs-Elemente der Dächer mit schwarzen Platten zu belegen und die zwischen den Bedeckungs-Elementen und den-Platten durch eigenen Auftrieb anfallende Warmluft zu verwenden.Means are known by which the usual roof coverings are converted into solar collectors. So it is suggested to cover the covering elements of the roofs with black tiles and those between the covering elements and the tiles to use warm air generated by its own buoyancy.
Da die oberhalb der Platten vorhandene Warmluft durch Konvektion und die in den Platten vorhandene Wärme durch Strahlung verloren geht, nutzen solche Pla+ten die Sonnenenergie nur mangelhaft aus. Die Ausschaltung solcher Verluste durch Abdeckung der Platten rait Hilfe von Platten aus Glas oder Kunststoffen sind offensichtlich beträchtlich aufwendiger.Because the warm air present above the plates is lost through convection and the heat present in the plates is lost through radiation such plates make insufficient use of solar energy. Eliminating such losses by covering the plates is rait The help of sheets of glass or plastics is obviously considerable more elaborate.
Durch die Dachbedeckungsplatte nach dem Gebrauchsmuster werden diese Mängel auf einfachste Weise behoben. Diese Platte besteht aus einseitig sonnenstrahlungsabsorbierendem Blech oder Kunststoff, dessen wesentliches Merkmal es ist, daß es gelocht oder siebartig ausgebildet ist. Der Absorber ist über die üblichen Bedeckungs-Elemente gelegt. Zwischen den letzten und der Absorberplatte bildet sich ein Hohlraum, der durch die Mulde entsteht, die jedes handelsübliche Bedeckungselement aufweist. So entsteht ein Kanal, in welchem die erwärmte Luft aufwärts strömt. Dies« Aufwärtsströmung saugt αίε an der Außenoberfläche des Absorbers befindliche Warmluft durch die Löcher oder das Siebgewebe in das Innere des Kanals. Die äußere Luftbewegung kann daher diese Warmluft nicht mehr abtragen, sie kommt der Anlage zur Erzeugung von Warmluft zugute; der Wirkungsgrad der Anlage wird erhöht.These deficiencies are remedied in the simplest way by the roof covering panel according to the utility model. This plate consists of One-sided solar radiation-absorbing sheet metal or plastic, the main feature of which is that it is perforated or like a sieve is trained. The absorber is above the usual covering elements placed. A cavity is formed between the last and the absorber plate, which is created by the hollow, which every commercially available Has covering element. This creates a channel in which the heated air flows upwards. This upward flow sucks in αίε Warm air located on the outer surface of the absorber through the holes or the screen mesh into the interior of the duct. The external air movement can therefore no longer remove this warm air, it benefits the system for generating warm air; the efficiency of the Plant is increased.
In weiterer Ausbildung der Dachbedeckungspxatte kann sie auf ihrer, den Bedeckungs-Elementen zugewandten Unterseite quer zu ihrer Längsrichtung mit Isolierstreifen ausgestattet sein, die im Abstand derIn further training of the roof covering, it can be used on its, the cover elements facing underside be equipped transversely to their longitudinal direction with insulating strips that are spaced from the
Breite der Bedeckunge-Elemente angeordnet sind. Mit Hilfe dieser Isolieretreifen wird erreicht, daß der Absorber auf den Bedeckungs- Elementen befestigt werden kann, der Querschnitt des Kanals ver größert und eine direkte Leitung der Wärme vom Absorber in die Dachbedeckung unterbunden wird. Width of the cover elements are arranged. With the help of this insulating strip it is achieved that the absorber can be attached to the covering elements, the cross-section of the channel is enlarged and a direct conduction of heat from the absorber into the roof covering is prevented.
Um zu verhindern, daß von der Oberfläche des Absorbers Wärme in Gestalt von Strahlung verloren geht, ist vorgesehen, daß er auf seiner der Strahlung zugewandten Seite selektiv beschichtet ist; die Emission der infraroten Strahlung wird verringert.In order to prevent heat from being lost in the form of radiation from the surface of the absorber, provision is made for it to be selectively coated on its side facing the radiation; the emission of infrared radiation is reduced.
Der Gegenstand des Gebrauchsmusters ist in den Figuren 1 und 2 verdeutlicht. Figur 1 stellt einen Längsschnitt, Figur 2 einen Querschnitt einer Dachbedeckungsplatte dar. Die Bedeckungs-Elemente 1 sind als wellenförmig ausgebildet dargestellt. Über diese ist die Absorberplatte 2 gelagert. Mit den Distanz-Streifen 3 ist die Absorberplatte über den Bedeckungs-Elementen fixiert. Durch die Löcher des Absorbers 2 tritt die warme Luft 4 aus der grenznahen Schicht der Oberfläche des Absorbers in den Kanal 5 ein. Die erwärmte Luft kann aus dem Kanal 5 in einen Sarnmelkanal 8 austreten und von dort beliebig verwertet werden. The subject matter of the utility model is illustrated in FIGS. FIG. 1 shows a longitudinal section and FIG. 2 shows a cross section of a roof covering panel. The covering elements 1 are shown as undulating. The absorber plate 2 is mounted via this. The absorber plate is fixed over the covering elements with the spacer strips 3. The warm air 4 enters the channel 5 through the holes in the absorber 2 from the layer of the surface of the absorber close to the border. The heated air can exit from the channel 5 into a Sarnmel canal 8 and from there can be used as desired.
Die dem Absorber zugewandte Seite der Dachbedeckung 1 ist mit einer Folie 6 belegt, welche die infrarote Strahlung reflektiert. Die Dachbedeckung ist an ihrer Oberseite rillen- oder kalottenförmig ausgenommen, so daß sich zwischen der Folie 6 und der Dachbedeckung abgeschlossene Luftzwischenräume 7 ergeben, die eine Isolierung bewirken.The side of the roof covering 1 facing the absorber is provided with a Foil 6 is covered, which reflects the infrared radiation. The roof covering is grooved or dome-shaped on its upper side, so that there are closed air spaces 7 between the film 6 and the roof covering, which provide insulation cause.
