Abstract

The heat removal turbine consists of turbine blades (2) and belts (3), plus a hollow shaft (4) which provides torque. An air-gas mixture is passed through the fluttering belts and an air-gas-mixture guide from the outside to the inside, removing the maximum heat energy over a short distance. There may be several turbine wheels (1) on the same axis.

Description

Die vorliegende Erfindung betrifft eine Konstruktion einer Thermoentzugsturbine.The present invention relates to a construction of a thermal extraction turbine.

Bekannt ist die Stromerzeugung aus Windkraft Durch die Rotorblätter werden dem Luftstrom Energie entzogen.The generation of electricity is known from Wind power through the rotor blades energy is extracted from the air flow.

Die DE 199 41 323 C2 offenbart eine Turbomaschine axialer Bauart für ein polyphasisches Fluid mit spiralförmig verwundenen Bändern oder eine aus wenigstens drei Teile bestehende Beschaufelung zwischen den Schaufeln des Rotors, um innig die flüssige und gasförmige Phase zu vermischen.The DE 199 41 323 C2 discloses an axial type turbomachine for a polyphasic fluid with spirally twisted ribbons or a blading consisting of at least three parts between the blades of the rotor to intimately mix the liquid and gaseous phases.

Die DE 199 09 899 A1 zeigt wie die eigentliche Beschaufelung eines Rotors aktiv über Aktuatoren elektrisch angesteuert werden, um den Arbeitsbereich einer Strömungsmaschine mit guten Wirkungsgrad zu erweitern.The DE 199 09 899 A1 shows how the actual blading of a rotor is actively controlled electrically using actuators in order to expand the working area of a turbomachine with good efficiency.

Die vorliegende Erfindung hat es sich zur Aufgabe gestellt, eine Turbine zu schaffen die bei minimalem Druckunterschied einen maximalen Wärmeentzug erreicht.The present invention has it set themselves the task of creating a turbine with minimal Pressure difference reaches a maximum heat extraction.

Die Lösung dieser Aufgabe gelingt mit gekrümmten Turbinenschaufeln und frei schwingenden Bändern. Dabei wird der Luft-/Gasstrom von außen nach innen geführt.This task is solved with curved Turbine blades and freely vibrating belts. The air / gas flow from the outside to led inside.

Nimmt die Geschwindigkeit der Luft-/Gasströmung zu, so widersetzen sich die flatternden Bänder überproportional und geben dabei Drehmoment über die Turbine ab.If the speed of the air / gas flow increases, the fluttering bands disproportionately resist and give Torque above the turbine.

Die flatternden Bänder erfüllen in der Konstruktion mehrere Aufgaben gleichzeitig. Zum einen können sie über die Befestigung Drehmoment an das Turbinenrad abgeben. Zum anderen wirken zwei Bänder zusammen wie ein Schlauchventil. Dabei wird der Luft-/Gasstrom ständig verdichtet und entspannt, verzögert und beschleunigt. Durch diese Bewegung wird dem Luft-/Gasstrom die maximale Wärmeenergie auf einem relativ kurzen Weg entzogen.The fluttering bands fulfill several in the construction Tasks simultaneously. For one, they can be tightened using torque to the turbine wheel. On the other hand, two bands work together like a hose valve. The air / gas flow is constantly compressed and relaxed, delayed and accelerated. Through this movement the air / gas flow becomes maximum thermal energy withdrawn in a relatively short way.

Die Turbinenschaufeln müssen gekrümmt sein und können aus Lochblechen hergestellt werden.The turbine blades must be curved and can be made from perforated sheets.

Mehrere dieser Turbinenräder können auch auf einer Achse angebracht werden um durch einen Wiederholungsprozess noch mehr Wärme zu entziehen.Several of these turbine wheels can also be used an axis can be attached around by a repetition process even more warmth to withdraw.

Die Bänder können auch durch andere schwingungsfähigen Konstruktionselemente gebildet werden.The belts can also be constructed using other vibratory elements be formed.

Dabei zeigt:It shows:

1 eine erfindungsgemäße Anordnung der Thermoentzugsturbine mit Bändern. 1 an inventive arrangement of the thermal extraction turbine with tapes.
