Nachteilig ist hierbei, daß mit der Erwärmung dieser Elemente oder Zellen auf bzw. über eine gewisse Temperatur sich deren elektrischer Widerstand erheblich erhöht, wodurch sich aber der Wirkungsgrad und damit die Ausbeute an elektrischer Energie in einer solchen Anlage merklich reduziert. Die Erwärmung der Elemente oder Zellen erfolgt nicht nur durch die Sonneneinstrahlung, sondern auch durch den von ihnen erzeugten und damit in ihnen fließenden Strom. Hierdurch wird die pro Zelle oder Element abgegebene Spannung verringert, mit der oben genannten Konsequenz des Leistungsabfalls.The disadvantage here is that with the heating of these elements or Cells at or above a certain temperature, their electrical resistance increases significantly increased, but this increases the efficiency and thus the yield of electrical Noticeably reduced energy in such a system. The heating of the elements or Cells takes place not only through solar radiation, but also through that of electricity generated in them and thus flowing in them. This will increase the per cell or element output voltage is reduced, with the consequence of the above Performance degradation.
Der Erfindung liegt die Aufgabe zugrunde, eine energiewirtschaftlich sinnvolle Lösung des vorgenannten Problems zu schaffen, insbesondere in einer technisch einfachen und problemlosen Bauweise.The invention is based on the object of an energy-efficient to create a sensible solution to the aforementioned problem, especially in a technical one simple and problem-free construction.
Zur Lösung dieser Aufgabe sieht die Erfindung in erster Linie vor, daß die Verkleidungen, Platten oder dergleichen eine Kühlung der Elemente oder Zellen durch ein Fluid aufweisen, wobei das Fluid sich in einem Thermokreislauf der zugehörigen Anordnung befindet und von dessen kühlen Ausgangsseite zu den Elementen, Platten oder dergleichen geleitet ist. Hiermit werden zugleich zwei Vorteile erreicht.To solve this problem, the invention primarily provides that the linings, panels or the like a cooling of the elements or cells have by a fluid, wherein the fluid is in a thermal circuit of the associated Arrangement is located and from its cool exit side to the elements, plates or the like is directed. This achieves two advantages at the same time.
Zum einen werden die Elemente oder Zellen gekühlt, so daß sich ihr elektrischer Widerstand nicht in schädlicher Weise erhöht. Zum anderen wird diese Wärme der Gesamtanordnung zugeführt, z. B. einem Wärmetauscher. Man erhält also eine zweifache Erhöhung des thermischen Wirkungsgrades.For one, the elements or cells are cooled so that you can electrical resistance does not increase in a detrimental way. On the other hand, this is Heat supplied to the overall arrangement, e.g. B. a heat exchanger. So you get a two-fold increase in thermal efficiency.
Gemäß einer bevorzugten Ausführungsform der Erfindung ist vorgesehen, daß das Fluid im freien Fall und drucklos durch Hohl- oder Innenräume der Verkleidungen, Platten oder dergleichen hindurch fließt. Dadurch werden Dichtungsprobleme vermieden, die bei einem in einem geschlossenen System unter Druck hindurch geführten Fluid auftreten würden. Insbesondere ist hierdurch die Gefahr vermieden, daß sich unter Druck stehender Dampf bildet, der bei einem unter Druck stehenden geschlossenen System unter ungünstigen Umständen zur Explosion führen kann.According to a preferred embodiment of the invention it is provided that the fluid in free fall and without pressure through cavities or interiors of the cladding, Plates or the like flows through it. This avoids sealing problems, that of a fluid passed through under pressure in a closed system would occur. In particular, this avoids the risk of getting under Forms pressurized steam, that of a pressurized closed System can lead to an explosion under unfavorable conditions.
Als Fluid wird in der Regel Wasser zur Verwendung kommen, obgleich die Erfindung hierauf nicht beschränkt ist. Mit der Erfindung wird nicht nur die erläuterte Eigenwärme der Elemente oder Zellen, sondern auch die hieran entstehende sogenannte Stauwärme abgeführt. Die Beseitigung dieser Stauwärme kann gemäß einem weiteren Gedanken der Erfindung zusätzlich noch dadurch erfolgen, daß eine Absaugvorrichtung für die die Elemente, Zellen oder Platten umgebende Luft vorgesehen ist.As a rule, water will be used as the fluid, although the invention is not limited to this. With the invention, not only that explained intrinsic heat of the elements or cells, but also the resulting heat so-called accumulated heat dissipated. The elimination of this accumulated heat can according to a further ideas of the invention also take place in that a suction device is intended for the air surrounding the elements, cells or plates.
