Description
BeschrDescription
Die Erfindung findet Anwendung bei Vakuum-Flachkollektoren, die zur Gewinnung von Energie, vor allem in Haushalten, zum Einsatz kommen.The invention is applied to vacuum flat collectors, which are used to generate energy, especially in households.
Ziel der Erfindung ist es, das Kollektorkonstruktionsprinzip zu vereinfachen, um so mit geringerem Aufwand genannte Flachkollektoren herstellen zu können.The aim of the invention is to simplify the collector construction principle in order to be able to produce so-called flat collectors with less effort.
Bekannt ist, daß herkömmliche Vakuum-Flachkollektoren aus mindestens fünf verschiedenen Teilen, wie Rahmen, Absorber, Oberseite und Unterseite sowie Stützelementen bestehen, wobei die Rahmen, die Ober- und Unterseite und die punktuellen Stützelemente miteinander verklebt werden müssen. Auch der Einsatz von Platten, die die Stützelemente am richtigen Ort fixieren, senken den Fertigungsaufwand nicht wesentlich.It is known that conventional vacuum flat collectors consist of at least five different parts, such as the frame, absorber, top and bottom, and support elements, whereby the frame, top and bottom, and the point support elements have to be glued together. Even the use of plates that fix the support elements in the right place does not significantly reduce the production effort.
Nach der DD PS 156 880 ist ein Sonnenkollektor mit Doppelscheibeneffekt bekannt. Hierbei sind in einem Gehäuse ein Absorberelement, ein herkömmlicher Plattenheizkörper, welcher mit Befestigungselementen und einer Arretierung für die Zweitabdeckung versehen ist, angeordnet. Das Absorberelement lagert auf Distanz- und Federelementen aus Gummi.According to DD PS 156 880, a solar collector with a double pane effect is known. An absorber element, a conventional panel radiator, which is provided with fastening elements and a locking device for the secondary cover, is arranged in a housing. The absorber element rests on spacers and spring elements made of rubber.
Nach der DE PS 2643 746 ist ein weiterer Sonnenkollektor bekannt, dessen Absorber aus einem hochflexiblen Werkstoff besteht und daß die den Absorber bildenden Profile als Oberteil einstückig mit einer Stützplatte verbunden sind. Kanäle an den Profilenden sind mittels Verbindungsschläuchen verbindbar.According to DE PS 2643 746, another solar collector is known whose absorber is made of a highly flexible material and in which the profiles forming the absorber are connected as an upper part in one piece to a support plate. Channels at the ends of the profiles can be connected using connecting hoses.
Der Absorber ist von einem erhöhten Gehäuse umgeben und mit einer strahlungsdurchlässigen Folie abgedeckt.The absorber is surrounded by a raised housing and covered with a radiation-permeable film.
Nach der DE OS 3611769 ist ein Vakuum Sonnenkollektor bekannt, welcher aus einer nahtlos tiefgezogenen Wanne, welche einen Absorber und Leitungen für das Wärmetransportmedium enthält, einen Rand aufweist, auf welchem die Wanne abdeckende strahlungsdurchlässige Scheibe aufliegt, die von Stützelementen abgestützt wird.According to DE OS 3611769, a vacuum solar collector is known which consists of a seamless deep-drawn tub containing an absorber and lines for the heat transport medium, and has an edge on which a radiation-permeable disk covering the tub rests, which is supported by support elements.
Die im Stand der Technik gefundenen Lösungen sind im Verhältnis zur vorliegenden erfinderischen Lösung in ihrer Herstellung zu aufwendig.The solutions found in the prior art are too complex to produce compared to the present inventive solution.
Aufgabe der Erfindung ist es, den technischen Aufwand bei der Herstellung von Vakuum-Flachkollektoren zu senken.The object of the invention is to reduce the technical effort in the production of vacuum flat collectors.
Erfindungsgemäß wird das dadurch erreicht, in dem eine Integration der Stützelemente in die Ober- und Unterseite konstruktiv erfolgt, wodurch auf dem Rahmen verzichtet werden kann.According to the invention, this is achieved by structurally integrating the support elements into the top and bottom, which means that the frame can be dispensed with.
Es kommt ein Vakuum-Flachkollektor in Anwendung, der in seinem Aufbau aus dem aus Plaste bestehenden Ober- und Unterteil und dem Absorber besteht.A vacuum flat collector is used, which consists of the upper and lower parts made of plastic and the absorber.
Die Form des Ober- und Unterteils ist bei geeigneter Technologie identisch, was die Herstellung durch Verwendung des gleichen Werkstückes zuläßt.The shape of the upper and lower parts is identical with suitable technology, which allows production using the same workpiece.
In zur Verstärkung vorgesehenen Eckstabilisatoren sind Bohrungen für Befestigungselemente eingepreßt. Die Stützelemente gehen zweckmäßigerweise durch Bohrungen im Absorber und berühren den Absorber nicht.Holes for fastening elements are pressed into the corner stabilizers intended for reinforcement. The support elements conveniently go through holes in the absorber and do not touch the absorber.
Technologisch von Vorteil ist, daß an einigen Seilen die Stützelemente den Absorber fixieren.A technological advantage is that the support elements on some ropes fix the absorber.
Zur Minimierung der Materialstärke können Stege zwischen den StUtzelementen mit eingepreßt werden. Ober- und Unterseite werden miteinander verschweißt und danach wird der Kollektor evakuiert.To minimize the material thickness, webs can be pressed in between the support elements. The top and bottom are welded together and then the collector is evacuated.
Das Ober- und Unterteil wird aus sonnen- und wärmebeständiger Preßplaste hergestellt, wobei das Unterteil verspiegelt ist.The upper and lower parts are made of sun and heat resistant molded plastic, with the lower part being mirrored.
Die Erfindung soll nachstehend an Hand von 2 Ausführungsbeispielen näher erläutert werden.The invention will be explained in more detail below using two exemplary embodiments.
Die dazugehörigen Zeichnungen zeigen:The accompanying drawings show:

Nach Fig. 1 besteht der Vakuum-Flachkollektor aus der Oberseite ^Jr, der Unterseite/^, wobei beide Seiten identisch sind, aus wärme- und sonnenbeständiger Preßplaste bestehen und die Unterseite verspiegelt ist.According to Fig. 1, the vacuum flat collector consists of the top side ^Jr, the bottom side/^, whereby both sides are identical, made of heat and sun-resistant molded plastic and the bottom side is mirrored.
Der Kollektor ist freitragend und rahmenlos. Die Stützelemente sind Bestandteil der Ober- und Unterseite 1,2.The collector is self-supporting and frameless. The support elements are part of the top and bottom 1,2.
Bohrungen 5 für die Befestigungselemente sind in die Unterseite 1 mit eingearbeitet, wobei zur Minimierung der Materialstärke Stege 7 zwischen die Stützelemente 6 eingearbeitet werden können. Um kleinere Flächenquadrate zu erreichen, verlaufen die Stege diagonal. In jedem zweiten Kreuzpunkt 8 ist ein Stützelement 6 integriert.Ober- und Unterseite 1,2 werden verschweißt.Holes 5 for the fastening elements are incorporated into the underside 1, whereby webs 7 can be incorporated between the support elements 6 to minimize the material thickness. To achieve smaller surface squares, the webs run diagonally. A support element 6 is integrated into every second intersection point 8. The top and bottom 1,2 are welded.

Nach Fig. 2 sind die Ober- und Unterseite 1,2 nicht identisch. Eckverstärkungen 4 zur Aufnahme der Befestigungselemente können entfallen.According to Fig. 2, the top and bottom sides 1,2 are not identical. Corner reinforcements 4 for holding the fastening elements can be omitted.
Zur Beherrschung unterschiedlicher Ausdehnungskoeffizienten zwischen Absorber 3 und Kollektorgehäuse bei unterschiedlichen Materialeinsatz können durch geeignete Gummidichtelemente in den Durchführungen beherrscht werden.To control different expansion coefficients between absorber 3 and collector housing when using different materials, suitable rubber sealing elements in the feedthroughs can be used.
Nach Fig. 3 werden Stützelemente 6 nur in die Unterseite 1 des Kollektors eingearbeitet, was aber besondere Anforderungen an die Abdichtung stellt, wenn für die Oberseite 2 beispielsweise eine Glasplatte verwendet wird.According to Fig. 3, support elements 6 are only incorporated into the underside 1 of the collector, which, however, places special demands on the sealing if, for example, a glass plate is used for the upper side 2.
