Abstract
Description
Die Erfindung geht von dem von G. Ranque beschriebenen Effekt aus (J. Physique Radium (7)4,1125).The invention proceeds from that described by G. Ranque Effect from (J. Physique Radium (7) 4.1125).
Dabei strömt Druckluft durch eine tangentiale Düse in einen Wälzbehälter ein, der aus einem beiderseits offenen Rohr besteht. Dabei stellt man fest, daß sich die Luft unter dem Einwirken der Zentrifugalkraft in einen warmen Anteil am Rohrmantel und einen kalten Anteil in der Rohrachse zerlegt. Rudolf Hilsch ver besserte diese Anordnung 1946 (Zeitschrift für Natur forschung I, S. 208-214 [1946]), um einen Kälteprozeß mit möglichst hohem Nutzeffekt zu erzielen. Dabei kam er auf eine Anordnung gemäß Fig. 1. Der durch die Düse eintretende Luftstrahl wird in eine schraubenförmige Drehströmung versetzt. Durch die Fliehkraft und die innere Reibung dieser Drehströmung wird das Gas im Bereich der Rohrachse stark expandiert und kühlt sich dabei ab (siehe Fig. 3). Durch innere Reibung gleichen sich die kinetischen Energien des kalten und heißen Gases an. Fig. 2 zeigt das Wirbelrohr im Längsschnitt. Durch eine Drossel auf der linken Seite erzwingt man das Entweichen des achsnahen, kälteren Gasanteils durch eine Blende nach rechts.Compressed air flows through a tangential nozzle into a roller container, which consists of a tube that is open on both sides. It is found that the air breaks down under the action of the centrifugal force into a warm portion of the tube shell and a cold portion in the tube axis. Rudolf Hilsch improved this arrangement in 1946 (Zeitschrift für Naturforschung I, pp. 208-214 [1946]) in order to achieve a cooling process with the greatest possible efficiency. He came up with an arrangement according to FIG. 1. The air jet entering through the nozzle is set into a helical three-way flow. Due to the centrifugal force and the internal friction of this rotary flow, the gas in the region of the tube axis is greatly expanded and cools down in the process (see FIG. 3). The kinetic energies of the cold and hot gas adjust due to internal friction. Fig. 2 shows the vortex tube in longitudinal section. A throttle on the left-hand side forces the colder gas component close to the axis to escape through a panel to the right.
Das Wirbelrohr trennt also einen homogenen Gasstrahl in einen Anteil mit tiefer und hoher Temperatur.The vortex tube thus separates a homogeneous gas jet in a portion with low and high temperature.
Genauso ist es möglich Gasgemische wegen der unter schiedlichen Dichte ihrer Komponenten zu trennen, sowie feste Partikel aus dem Gas auszuschleudern (z. B. Entrußung von Abgasen). Bei Verbrennungsprozessen können Wirbelrohre zur Erhöhung des Wirkungsgrades eingesetzt werden.It is also possible to use gas mixtures because of the below separate the different densities of their components, as well as ejecting solid particles from the gas (e.g. Exhaust emissions). In combustion processes can use vortex tubes to increase efficiency be used.
In vorliegender Erfindung wird mittels einer Laval düse das Gas mit Überschallgeschwindigkeit in den Wälzbehälter eingeleitet (siehe Fig. 3).In the present invention, the gas is introduced into the rolling container at supersonic speed by means of a Laval nozzle (see FIG. 3).
Dadurch erreicht man 2 Effekte, die beide eine Ver besserung des Wirkungsgrades des Wirbelrohrs bewirken:This gives you two effects, both of which are ver Improve the efficiency of the vortex tube:
Zum Ersten wird bei gleichem Überdruck eine wesentlich höhere Eintrittsgeschwindigkeit erreicht. Dies bedingt größere kinetische Energie und dadurch stärkere Abkühlung bzw. höhere Zentrifugalkraft.First, with the same overpressure, one becomes essential reached higher entry speed. This requires greater kinetic energy and therefore stronger Cooling down or higher centrifugal force.
Zweitens erhöhen die im Wälzbehälter auftretenden Verdichtungsstöße die innere Reibung, und die kinetische Energie wird in verstärktem Maß von den achsfernen Schichten abgegeben.Second, increase those that occur in the rolling container Shocks the internal friction, and the kinetic energy is increased by the delivered off-axis layers.
Durch diese Erfindung wird die Wirkung des Wirbelrohrs sowohl als Kälteprozeß als auch bei der Trennung von Gas- und Isotopengemischen entscheidend verbessert.By this invention the effect of the vortex tube both as a cold process and in the separation of Gas and isotope mixtures significantly improved.
Ein Ausführungsbeispiel für eine Kühlung mit Hilfe eines Wirbelrohrs sei unter Bezugnahme auf Fig. 4 erläutert. Bei modernen Verkehrsflugzeugen wird die Passagierkabine druckbelüftet. Dazu entnimmt man den Triebwerken Druckluft im Bereich des Verdichters. Diese Verdichterzapfluft weist Temperaturen um 250°C auf und muß deshalb zunächst gekühlt werden. Diese Kühlung soll mit einem Wirbelrohr gemäß Anordnung Fig. 4 durchgeführt werden. Die heiße Zapfluft wird zuerst durch den Wärmetauscher (1) geleitet, in dem sie durch Kühlluft aus der Umgebung vorgekühlt wird. Im Wirbel rohr (2) wird sie nun in einen heißen und einen kalten Anteil getrennt. Im Mischventil (5) werden anschließend der heiße und kalte Luftstrom entsprechend den Bedürf nissen der Klimatisierung wieder gemischt.An exemplary embodiment for cooling with the aid of a vortex tube will be explained with reference to FIG. 4. In modern commercial aircraft, the passenger cabin is pressurized. To do this, compressed air is drawn from the engines in the area of the compressor. This compressor bleed air has temperatures of around 250 ° C and must therefore first be cooled. This cooling is to be carried out with a vortex tube according to the arrangement in FIG. 4. The hot bleed air is first passed through the heat exchanger ( 1 ), where it is pre-cooled by cooling air from the surroundings. In the vortex tube ( 2 ) it is now separated into a hot and a cold portion. In the mixing valve ( 5 ), the hot and cold air flow is then mixed again according to the needs of the air conditioning.
Überschüssige Heißluft wird vor dem Wärmetauscher (1) wieder in den Kreislauf eingeleitet. Ein Wasser abscheider (3) im Kaltluftkanal fällt bei der Ab kühlung entstandene Wassertröpfchen aus. Ein integrierter Temperaturfühler gibt Signale an das Ventil (4), über das bei Bedarf Heißluft zugemischt werden kann, um Eisbildung im Kaltluftkanal und im Wasserabscheider zu vermeiden.Excess hot air is reintroduced into the circuit before the heat exchanger ( 1 ). A water separator ( 3 ) in the cold air duct precipitates water droplets that occur during cooling. An integrated temperature sensor sends signals to the valve ( 4 ), via which hot air can be added if necessary to prevent ice formation in the cold air duct and in the water separator.
Man beachte die erwünschte Rückwirkung des Mischventils (5) auf die Wirkung des Wirbelrohrs (2). So wird bei reduzierter Abnahme von heißer Luft die Abgabe von kalter Luft durch die Blendenöffnung erhöht.Note the desired reaction of the mixing valve ( 5 ) to the effect of the vortex tube ( 2 ). With reduced consumption of hot air, the release of cold air through the aperture is increased.
Die Vorteile dieser Ausführung gegenüber derjenigen mittels einer Expansionsturbine, wie sie zur Zeit zur Anwendung kommt, sind:The advantages of this design over that by means of an expansion turbine, as is currently the case are used are:
- 1. Wegfall eines Wärmetauschers1. Elimination of a heat exchanger
- 2. Geringeres Gewicht, dadurch größere Nutzlast2. Lighter weight, therefore greater payload
- 3. Keine beweglichen Teile, dadurch zuverlässiger 3. No moving parts, therefore more reliable
- 4. Weniger Leistungsverlust der Triebwerke durch geringere Zapfluftentnahme.4. Less loss of power from the engines less bleed air extraction.
