Abstract
Stirlingmotor, ausgeführt als großvolumiger Flachplatten Doppelstirling mit nur einer Kurbelwelle in einem unter Gasdruck stehendem Gehäuse, dadurch gekennzeichnet, dass die zwei Zylinder der Arbeitskolben (8) sich gegenüber liegend befinden.Stirling engine, designed as a large-volume flat plate double Stirling with only one crankshaft in a housing under gas pressure, characterized in that the two cylinders of the working pistons (8) are located opposite one another.
Description
Heutige Stirlingmotoren sind Modellstirlingmotoren für die Veranschaulichung der Funktion des Stirlingmotors und werden als Spielzeug gebaut.Today's Stirling engines are model Stirling engines for illustrating the function of the Stirling engine and are built as toys.
Heutige Hochtemperaturstirlingmotoren werden für die Erzeugung von Elektrizität unter Zuhilfenahme von Sonnenkollektoren oder Geothermie gebaut.Today's high-temperature Stirling engines are built for the generation of electricity with the help of solar panels or geothermal energy.
Die Hochtemperaturstirlingmotoren erfordern hohe Ansprüche an das Material sowie die Gasabdichtungen der Arbeitskolben. Diese Stirlingmotoren -sogenannte Heißgasmotorenlaufen mit einer hohen Drehzahl und benötigen einen hohen Temperaturunterschied der warmen zur kalten Seite am Zylinder des Verdrängerkolbens.The high-temperature Stirling engines place high demands on the material and the gas seals on the working pistons. These Stirling engines - so-called hot gas engines - run at a high speed and require a large temperature difference from the warm to the cold side on the cylinder of the displacement piston.
Der neue Stirlingmotor wird als großvolumiger Flachplattendoppelstirling mit nur einer Kurbelwelle
Der neue Stirlingmotor braucht nur einen geringen Temperaturunterschied, hat eine geringe Drehzahl und arbeitet im Niedrigtemperaturbereich.The new Stirling engine needs only a small temperature difference, has a low speed and works in the low temperature range.
Durch das Verdichten des Gases innerhalb des Gehäuses sowie des Stirlingmotors, erhöhen sich die Teilchen pro Mol. Werden mehr Teilchen pro Mol erwärmt bzw. abgekühlt, ergibt sich ein höherer Druckunterschied zwischen erwärmten und abgekühltem Gas als ohne Verdichtung und somit eine höhere Leistung.By compressing the gas inside the housing and the Stirling engine, the particles per mole increase. If more particles are heated or cooled, the pressure difference between heated and cooled gas is higher than without compression and thus higher performance.
Der Doppelstirlingmotor besteht aus zwei separaten Zylindern, in denen sich jeweils ein Flachplattenverdrängerkolben befindet. An den Zylinderwänden sowie deren Ober- und Unterseite sind für die warme und kalte Seite getrennte Rohre montiert. Durch diese Rohre fließt das jeweilige warme bzw. kalte Medium.The double Stirling engine consists of two separate cylinders, each with a flat plate displacement piston. Separate pipes for the warm and cold sides are mounted on the cylinder walls and their top and bottom. The respective warm or cold medium flows through these pipes.
Der Zylinder für den jeweiligen Arbeitskolben
Die Verdrängerkolben werden diskontinuierlich über Kurvenscheiben
Auf der Kurbelwelle befindet sich ein Schwungrad. Zum Starten des Stirlingmotors wird ein Starter die Schwungscheibe in Drehung versetzen.There is a flywheel on the crankshaft. To start the Stirling engine, a starter will set the flywheel in rotation.
Der Antrieb des Generators erfolgt durch ein Getriebe, dass mit der Kurbelwelle verbunden ist. Die Kurvenscheiben werden auch durch die Kurbelwelle angetrieben. Die Kraftübertragung erfolgt hierbei durch Zahnriemen.The generator is driven by a gearbox that is connected to the crankshaft. The cams are also driven by the crankshaft. The power is transmitted through toothed belts.
Das Gehäuse enthält ein Überdruckventil
Am Zylinder für den Verdrängerkolben ist ein Ventil
Am Zylinder für den Verdrängerkolben sind ein oder mehrere automatisch gesteuerte Ventile
Der „Null Druck Punkt“ ist ein Punkt innerhalb des Stirling Prozesses, an dem der Druck innerhalb des Stirlingmotors und des Gehäuses genau gleich ist. Dieses Ventil gleicht bei Druckschwankungen innerhalb des Gehäuses den Druck im Stirlingmotor wieder dem Druck im Gehäuse an.The “zero pressure point” is a point within the Stirling process at which the pressure within the Stirling engine and the housing is exactly the same. In the event of pressure fluctuations within the housing, this valve adjusts the pressure in the Stirling engine to the pressure in the housing.
Druckschwankungen entstehen durch Tages- und Nachttemperatur. Diese erzeugen eine Temperaturerhöhung oder -abkühlung des Gases innerhalb des Gehäuses
Um die durch Sonneneinstrahlung sowie normale Tageserwärmung auftretende Temperaturerhöhung entstehende Druckerhöhung auszugleichen, befindet sich innerhalb des Gehäuses ein Kompressor, der den überhöhten Gasdruck in den Druckluftbehälter abpumpt. Dieser Kompressor befindet sich deshalb innerhalb des Gehäuses, damit keine Leckagen in die Atmosphäre innerhalb des Kompressorsystems entstehen.In order to compensate for the increase in pressure caused by solar radiation and normal daily warming, there is a compressor inside the housing that pumps the excessive gas pressure into the compressed air tank. This compressor is therefore located inside the housing so that there are no leaks into the atmosphere inside the compressor system.
