Abstract
Description
Die Erfindung betrifft eine Strömungsmaschine für einen Energiewandler gemäß dem Oberbegriff des Patentanspruchs 1 sowie Brennstoffzelleneinrichtung mit einer solchen Strömungsmaschine.The invention relates to a turbomachine for an energy converter according to the preamble of patent claim 1 and fuel cell device with such a turbomachine.
Die
Ferner ist es aus dem allgemeinen Stand der Technik bekannt, bei Strömungsmaschinen wie beispielsweise bei elektrisch angetriebenen Turboladern Kugel- oder Luftlager zu verwenden, um ein Laufzeug der Strömungsmaschine zu lagern. Die dynamischen Luftlager umfassen dabei wenigstens eine Folie, mittels welcher das Laufzeug gelagert ist. Diese Luftlager erzeugen prinzipbedingt besonders hohe Reibungsverluste insbesondere gegenüber Kugellagern, wobei der größte Teil der Verluste bei Axiallagern anfällt. Entstehende Lagerverluste insbesondere in Form von Reibungsverlusten können dabei etwa zu 1/3 Radiallagern und zu ca. 2/3 Axiallagern zugeordnet werden. Aufgrund der entstehenden Verluste weisen Luftlager einen Kühlluftbedarf auf, welcher sich proportional zu den Reibverlusten aufteilt.Furthermore, it is known from the general state of the art to use ball bearings or air bearings in turbomachines, such as in electrically driven turbochargers, in order to support a rotor of the turbomachine. The dynamic air bearings comprise at least one film by means of which the running gear is mounted. Due to their inherent nature, these air bearings generate particularly high friction losses, in particular with respect to ball bearings, whereby the majority of the losses occur with axial bearings. Resulting bearing losses, in particular in the form of friction losses, can be assigned to about 1/3 radial bearings and about 2/3 axial bearings. Due to the resulting losses, air bearings have a cooling air requirement, which is divided in proportion to the friction losses.
Der
Darüber hinaus ist eine Lagereinrichtung vorgesehen, welche wenigstens ein als Punktlager ausgebildetes Axiallager umfasst, mittels welchem das Laufzeug in axialer Richtung gelagert ist. Gelingt die Darstellung einer besonders verlustarmen Lagerung des Laufzeugs, so kann der Gesamtwirkungsgrad der Strömungsmaschine beträchtlich erhöht werden.In addition, a bearing device is provided, which comprises at least one thrust bearing designed as a point bearing, by means of which the running gear is mounted in the axial direction. If the representation of a particularly low-loss storage of the running gear succeeds, the overall efficiency of the turbomachine can be considerably increased.
Es ist daher Aufgabe der vorliegenden Erfindung, eine Strömungsmaschine der eingangs genannten Art sowie eine Brennstoffzelleneinrichtung mit einer solchen Strömungsmaschine bereitzustellen, wobei die Strömungsmaschine einen besonders hohen Wirkungsgrad aufweist.It is therefore an object of the present invention to provide a turbomachine of the aforementioned type and a fuel cell device with such a turbomachine, wherein the turbomachine has a particularly high efficiency.
Diese Aufgabe wird durch eine Strömungsmaschine mit den Merkmalen des Patentanspruchs 1 gelöst. Vorteilhafte Ausgestaltungen mit zweckmäßigen und nichttrivialen Weiterbildungen der Erfindung sind in den übrigen Ansprüchen angegeben.This object is achieved by a turbomachine having the features of patent claim 1. Advantageous embodiments with expedient and non-trivial developments of the invention are specified in the remaining claims.
Um eine Strömungsmaschine der im Oberbegriff des Patentanspruchs 1 angegebenen Art zu schaffen, welche einen besonders hohen Wirkungsgrad aufweist, ist erfindungsgemäß wenigstens eine, an einer stromab des Verdichterrads angeordneten Abzweigstelle mit dem Verdichter fluidisch verbundene Abzweigleitung vorgesehen, über welche eine Radrücken des Turbinenrads mit einem an der Abzweigstelle herrschenden Druck beaufschlagbar ist. Dieser Druck ist dabei ein Verdichterauslassdruck, welcher vom Verdichter zum Radrücken des Turbinenrads und somit zur Turbine geführt ist.In order to create a turbomachine specified in the preamble of claim 1 species, which has a particularly high efficiency, according to the invention at least one, arranged at a downstream of the compressor wheel branch point with the compressor fluidly connected branch line provided via which a Radrücken the turbine wheel with a the branch point prevailing pressure can be acted upon. This pressure is a compressor outlet pressure, which is guided from the compressor to Radrücken the turbine wheel and thus to the turbine.
Dadurch können unterschiedliche Druckniveaus innerhalb der Strömungsmaschine geschickt genutzt werden, um auf die Lagereinrichtung wirkende Axialkräfte besonders gering zu halten und um so eine besonders verlustarme Lagerung des Laufzeugs zu realisieren. Dies führt zu einem besonders hohen Wirkungsgrad der Strömungsmaschine. Mit dieser Maßnahme können die normalerweise in einer solchen Strömungsmaschine entstehenden Axialkräfte auf etwa 30% reduziert werden. Das verdichterseitige Abzweigen des Drucks bzw. der verdichteten Luft und das Führen des Drucks bzw. der Luft zu der Turbine ermöglicht eine zumindest teilweise Kompensation von bei der Verdichtung entstehenden Axialkräften. Etwaig verbleibende Axialkräfte können durch das Punktlager reibungs- und verlustarm aufgenommen werden.As a result, different pressure levels can be cleverly used within the turbomachine in order to keep axial forces acting on the bearing device particularly low, and in this way to realize a particularly low-loss bearing of the running gear. This leads to a particularly high efficiency of the turbomachine. With this measure, the axial forces normally generated in such a turbomachine can be reduced to about 30%. The compressor-side branching of the pressure or the compressed air and the guiding of the pressure or the air to the turbine enables an at least partial compensation of axial forces arising during the compression. Any remaining axial forces can be absorbed by the point bearing friction and low loss.
Bei dem Punktlager handelt es sich um ein sogenanntes punktförmiges Lager, mittels welchem das Laufzeug unter Ausbildung eines zumindest im Wesentlichen punktförmigen Kontakts in axialer Richtung zwischen zwei Lagerteilen des Punktlagers in axialer Richtung gelagert ist.In the point bearing is a so-called punctiform bearing, by means of which the running gear is mounted to form an at least substantially point-shaped contact in the axial direction between two bearing parts of the point bearing in the axial direction.
Zur Erfindung gehört auch eine Brennstoffzelleneinrichtung, insbesondere für einen Kraftwagen, mit wenigstens einer Brennstoffzelle als Energiewandler zur Wandlung von chemisch gebundener Energie eines der Brennstoffzelle zuzuführenden Brennstoffs und eines Oxidationsmittels aus der Brennstoffzelle zuzuführender Luft in elektrische Energie. und mit einer erfindungsgemäßen Strömungsmaschine zum Versorgen der Brennstoffzelle mit verdichteter Luft. Die Strömungsmaschine weist einen sehr hohen Wirkungsgrad auf, so dass die Brennstoffzelle besonders effizient mit verdichteter Luft versorgt und somit effizient betrieben werden kann. Vorteilhafte Ausgestaltungen der erfindungsgemäßen Strömungsmaschine sind als vorteilhafte Ausgestaltungen der erfindungsgemäßen Brennstoffzelleneinrichtung anzusehen und umgekehrt.The invention also includes a fuel cell device, in particular for a motor vehicle, with at least one fuel cell as energy converter for the conversion of chemically bound energy of the fuel cell to be supplied fuel and an oxidizing agent from the Fuel cell to be supplied air into electrical energy. and with a turbomachine according to the invention for supplying the compressed air to the fuel cell. The turbomachine has a very high efficiency, so that the fuel cell can be supplied particularly efficiently with compressed air and thus operated efficiently. Advantageous embodiments of the turbomachine according to the invention are to be regarded as advantageous embodiments of the fuel cell device according to the invention and vice versa.
