Abstract
Description
Die Erfindung betrifft einen Abgasturbolader für einen Energiewandler, insbesondere eine Brennstoffzelle, gemäß dem Oberbegriff von Patentanspruch 1.The invention relates to an exhaust gas turbocharger for an energy converter, in particular a fuel cell, according to the preamble of patent claim 1.
Derartige Abgasturbolader für einen Energiewandler, insbesondere eine Brennstoffzelle, sind aus dem allgemeinen Stand der Technik hinlänglich bekannt.
Das Turbinengehäuse
Während des Betriebs des Energiewandlers, insbesondere der Brennstoffzelle, entsteht ein Abgas des Energiewandlers. Bei diesem Abgas handelt es sich im Falle der Brennstoffzelle um Luft, welche üblicherweise auch als Abluft bezeichnet wird. Das Abgas wird dem Turbinenrad

Der Wirkungsgrad von Strömungsmaschinen wie dem elektrisch angetriebenen Turbolader in Form des Abgasturboladers
Der Toleranzausgleich wird üblicherweise mit Distanzelementen, beispielsweise Distanzblechen, durchgeführt, welche an den Gehäusetrennstellen a, b zwischen das Turbinengehäuse
Im Rahmen des Toleranzausgleichs erfolgt beispielsweise zunächst eine Messung, mit deren Hilfe die für den Toleranzausgleich erforderliche Anzahl und/oder die erforderliche, in axialer Richtung verlaufende Dicke der Distanzelemente ermittelt werden. Anschließend erfolgt die Montage des Abgasturboladers
Es ist daher Aufgabe der vorliegenden Erfindung, einen Abgasturbolader der eingangs genannten Art zu schaffen, welcher eine besonders einfache Montage aufweist.It is therefore an object of the present invention to provide an exhaust gas turbocharger of the type mentioned, which has a particularly simple assembly.
Diese Aufgabe wird durch einen Abgasturbolader für einen Energiewandler, insbesondere eine Brennstoffzelle, mit den Merkmalen des Patentanspruchs 1 gelöst. Vorteilhafte Ausgestaltungen mit zweckmäßigen und nicht-trivialen Weiterbildungen der Erfindung sind in den übrigen Ansprüchen angegeben.This object is achieved by an exhaust gas turbocharger for an energy converter, in particular a fuel cell, 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 einen Abgasturbolader für einen Energiewandler, insbesondere eine Brennstoffzelle, der im Oberbegriff des Patentanspruchs 1 angegebenen Art zu schaffen, welcher eine besonders einfache Montage aufweist, ist es erfindungsgemäß vorgesehen, dass der Eintrittsdurchmesser des Turbinenrads gleich dem Austrittsdurchmesser ist. Mit anderen Worten weist das Turbinenrad einen TRIM von 100 auf. Dies bedeutet, dass eine in radialer Richtung äußere Kontur des Turbinenrads bei wenigstens einer vollständigen Umdrehung um die Drehachse einen gedachten Rotationskörper erzeugt, dessen außenumfangsseitige Mantelfläche zumindest im Wesentlichen die Form eines geraden Kreiszylinders aufweist, wobei die Drehachse die Längsmittelachse des geraden Kreiszylinders ist. Die Turbine ist somit als sogenannte Walzenturbine und das Turbinenrad als Walzenturbinenrad ausgebildet. Durch diese Form des Turbinenrads kann auf einen axialen Toleranzausgleich des Abgasturboladers verzichtet werden, da ein Spalt in radialer Richtung zwischen dem Turbinenrad und einem Turbinengehäuse der Radialturbine unabhängig von der axialen Position des Turbinengehäuses stets gleich bleibt.In order to provide an exhaust gas turbocharger for an energy converter, in particular a fuel cell, the type specified in the preamble of patent claim 1, which has a particularly simple assembly, it is inventively provided that the inlet diameter of the turbine wheel is equal to the outlet diameter. In other words, the turbine wheel has a TRIM of 100. This means that a radially outer contour of the turbine wheel generates at least one complete revolution about the axis of rotation an imaginary rotation body, the outer peripheral side surface has at least substantially the shape of a right circular cylinder, wherein the axis of rotation is the longitudinal center axis of the right circular cylinder. The turbine is thus designed as a so-called rolling turbine and the turbine wheel as a roller turbine wheel. By this form of the turbine wheel can be dispensed with an axial tolerance compensation of the exhaust gas turbocharger, since a gap in the radial direction between the turbine wheel and a turbine housing of the radial turbine regardless of the axial position of the turbine housing always remains the same.
Gleichzeitig ermöglicht das Turbinenrad die Darstellung eines effizienten und effektiven Betriebs des Abgasturboladers, mittels welchem der Energiewandler mit verdichteter Luft zu versorgen ist.At the same time, the turbine wheel enables the representation of an efficient and effective operation of the exhaust gas turbocharger, by means of which the energy converter is to be supplied with compressed air.
