Anlage 2: Beschreibung
2.1 Stand der Technik
Annex 2: Description
2.1 State of the art

Vorrichtungen, die Sonnenwärme direkt als Energiequelle benutzen, gibt es in verschiedenen Ausführungen. Devices that use solar heat directly as an energy source are available in various designs.

Der seit Beginn des 19. Jahrhunderts bekannte Stirling-Motor kann mithilfe eines Hohlspiegels auch mit Sonnenstrahlung betrieben werden. Das Prinzip der Schwerpunktverlagerung ist beim Bimetallmotor (Phywe, Art. 04235.00) und bei , .iem am 06.03.1988 vom ZDF in der Knoff-Hoff-Show gezeigten Gummirad realisiert, bei dem sich ein Gummiband unter Wärmeeinwirkung zusammenzieht und dabei ein Gewicht verschiebt.The Stirling engine, which has been known since the beginning of the 19th century, can also be operated with solar radiation using a concave mirror. The principle of shifting the center of gravity is implemented in the bimetal engine (Phywe, Art. 04235.00) and in the rubber wheel shown on March 6, 1988 by ZDF in the Knoff-Hoff show, in which a rubber band contracts under the influence of heat and shifts a weight in the process.

Zu erwähnen ist noch die als Spielzeug bekannte "Trinkende Ente", deren Funktion auf der Verdunstung einer leicht flüchtigen Flüssigkeit beruht. Die Aufgab«;, die durch den Erfindungsgegenstand gelöst werden soll, besteht darin, eine Vorrichtung zu konstruieren, die bei geringem technischen Aufwand eine höhere mechanische Leistung zuläßt als dies bei den bisher bekannten Anordnungen der Fall ist.Also worth mentioning is the "drinking duck" toy, which works by evaporating a volatile liquid. The problem to be solved by the invention is to construct a device that allows a higher mechanical performance with little technical effort than is the case with previously known arrangements.

Tt 2.2 Funktionsbeschreibung Tt 2.2 Functional description

Die Vorrichtung besteht aus drei oder mehreren Steigrohren (1), die in einer vertikalen Ebene sternförmig angeordnet sind. Der Stern ist um eine zu seiner Ebene senkrechten horizontalen Adise drehbar gelagert. An den beiden Enden eines Steigrohres befindet sich je ein Flüssigkeitsbehälter (3). Das Material für die Steigrohre ist beliebig, es muß sich jedoch ein Rohr mit gleichbleibendem Durchmesser daraus herstellen lassen. In den Steigrohr«) befindet sich je ein beweglicher Kolben (2), der die beiden Enden eines Steigrohres gasdicht voneinander trennt. Das Material des Kolbens muß so gewählt werden, daß er sich leicht beweglich und trotzdem absolut dicht in das Steigrohr einpassen läßt. Wichtig: Der Stempeldruck des Kolbens muß sich in der Größenordnung von 50 mbar bewegen, weil er in vertikaler Stellung des Steigrohres sonst zu stark "einsinkt".The device consists of three or more riser pipes (1) arranged in a star shape in a vertical plane. The star is mounted so that it can rotate around a horizontal axis perpendicular to its plane. At each end of a riser pipe there is a liquid container (3). The material for the riser pipes is optional, but it must be possible to make a pipe with a constant diameter. In each riser pipe there is a movable piston (2) which separates the two ends of a riser pipe from each other in a gas-tight manner. The material of the piston must be chosen so that it can be moved easily and yet fitted absolutely tightly into the riser pipe. Important: The piston's piston pressure must be in the order of 50 mbar, otherwise it will "sink" too much when the riser pipe is in the vertical position.

Continuation of Annex 2

Die Flüssigkeitsbehälter (3) enthalten ein saugfähiges Material, das mit einer leicht verdunstenden Flüssigkeit getränkt wird. Dadurch wird verhindert, daß Flüssigkeit in das Steigrohr läuft. Nach der Füllung der Flüssigkeitsbehälter muß die Luft aus dem System entfernt werden.The liquid containers (3) contain an absorbent material that is soaked with a liquid that evaporates easily. This prevents liquid from running into the riser pipe. After filling the liquid containers, the air must be removed from the system.

Bei Erwärmung eines Flüssigkeitsbehälters verdunstet die in ihm enthaltene Flüssigkeit und verschiebt den Kolben. Damit durch Kompression des Dampfes auf der anderen Seite des Kolbens dessen Verschiebung nicht behindert wird, muß der gegenüberliegende Flüssigkeitsbehälter gekühlt werden, um den komprimierten Dampf darin zur Kondensation zu bringen.When a liquid container is heated, the liquid it contains evaporates and moves the piston. To ensure that compression of the vapor on the other side of the piston does not hinder its movement, the opposite liquid container must be cooled in order to cause the compressed vapor in it to condense.

Durch die Verschiebung eines Kolbens verlagert sich der Schwerpunkt, und das Steigrohr dreht sich um seine Horizontalachse. Nach einer Sechsteldrehung des Steigrohr-Sterns (bei vier Steigrohren nach einer Achteldrehung) wiederholt sich dieser Vorgang beim nächsten Steigrohr.By moving a piston, the center of gravity shifts and the riser tube rotates around its horizontal axis. After a sixth of a turn of the riser tube star (after an eighth of a turn with four riser tubes), this process is repeated with the next riser tube.

Nach einer halben Drehung wird der vorher erwärmte Behälter gekühlt und umgekehrt.After half a turn, the previously heated container is cooled and vice versa.

Zur Gewährleistung einer hinreichend schnellen Temperaturänderung der Flüssigkeitsbehälter müssen diese aus gut wärmeleitfähigem Metall bestehen, das zur besseren Strahlungsabsorption mattschwarz lackiert wird. Außerdem kann die äußere Oberfläche der Flüssigkeitsbehälter durch geeignet geformte Bleche vergrößert werden.To ensure that the liquid containers can change their temperature quickly enough, they must be made of metal that conducts heat well and is painted matt black to improve radiation absorption. In addition, the outer surface of the liquid containers can be enlarged using suitably shaped metal sheets.

Variante:Variant:

Ein Nachteil der beschriebenen Anordnung ist, daß die Wärmestrahlung von schräg unten aufgenommen wird. Um Sonnenstrahlung direkt ausnutzen zu können, müssen die Flüssigkeitsbehälter flexibel mit den Steigrohren verbunden werden, so daß sie je nach Strahlungsrichtung in die richtige Position gebracht werden können.A disadvantage of the described arrangement is that the heat radiation is absorbed from below at an angle. In order to be able to use solar radiation directly, the liquid containers must be flexibly connected to the riser pipes so that they can be brought into the correct position depending on the direction of the radiation.

2.3 Intended use

In der Normalausführung, bei der die Strahlungswärme von unten zugeführt wird, eignet sich das Gerät z.B. als Blickfang für Schaufensterdekorationen. Zur Demonstration einer Energieumwandlung kann es als Lehrmittel dienen. Schließlich würde eine technisch ausgereifte Version die direkte Nutzung der Sonnenwärme zum Antrieb von kleinen Maschinen, z.B. von Bewässerungsanlagen, zulassen. Trotz des kleinen zu erwartenden Wirkungsgrades erscheint dies angesichts der Solarkonstante von ca. 1 kW/m sinnvoll.In the standard version, where the radiant heat is supplied from below, the device is suitable as an eye-catcher for shop window decorations, for example. It can be used as a teaching aid to demonstrate energy conversion. Finally, a technically sophisticated version would allow the direct use of solar heat to drive small machines, e.g. irrigation systems. Despite the low expected efficiency, this seems sensible in view of the solar constant of approx. 1 kW/m.
