Abstract
Description
Die Erfindung betrifft einen Strömungsverdichter für eine Brennkraftmaschine gemäß dem Oberbegriff des Patentanspruches 1.The The invention relates to a flow compressor for an internal combustion engine according to the preamble of claim 1.
Bekanntermaßen werden Abgasturbolader mit Radialverdichter als Aufladesysteme für Brennkraftmaschinen in Kraftfahrzeugen eingesetzt. Durch die sehr hohen Verdichterdrehzahlen wird die angesaugte Luft nicht nur verdichtet. Durch Luftverwirbelungen am Verdichterrad und besonders in den Spalten zwischen Verdichterrad und Verdichtergehäuse wird die Luft auch erwärmt.As is known, Turbocharger with radial compressor as charging systems for Internal combustion engines used in motor vehicles. By the very high compressor speeds, the intake air is not only compressed. Due to air turbulence on the compressor wheel and especially in the gaps between compressor wheel and compressor housing is the air also heated.

Bei sehr hohen Verdichterdrehzahlen wird die zu verdichtende Luft durch Reibung am Verdichterrad und insbesondere in den Spalten zwischen dem Verdichterrad und dem Gehäuse deutlich wärmer als bei einer adiabaten Verdichtung. Das heißt, dass der Luft im Strömungsverdichter nachteilig Wärme zugeführt wird, wodurch mehr Antriebsleistung erforderlich ist.at very high compressor speeds, the air to be compressed through Friction on the compressor wheel and in particular in the gaps between the Compressor and the housing much warmer as in an adiabatic compression. That means that the Air in the flow compressor adversely heat supplied becomes, whereby more drive power is required.

Die Aufgabe der Erfindung besteht darin einen Strömungsverdichter für eine Brennkraftmaschine bereitzustellen, bei dem auch bei sehr hohen Verdichterdrehzahlen die Ansaugluft im Wesentlichen adiabat verdichtet werden kann.The The object of the invention is a flow compressor for an internal combustion engine, in which also at very high compressor speeds, the intake air is substantially adiabatic can be compressed.
Die Aufgabe ist durch die Merkmale des Patentanspruches 1 gelöst. Vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen offenbart.The The object is solved by the features of claim 1. Advantageous developments of the invention are in the dependent claims disclosed.
Gemäß dem kennzeichnenden Teil des Anspruches 1 ist in einer, einen Verdichter-Spiralkanal umgebenden Begrenzungswand eines Spiralgehäuses ein Kühlkanal vorgesehen, der von einem Kühlfluid, etwa Kühlwasser aus einem Niedertemperaturkühlkreislauf, durchströmt ist. Mittels des spiralseitigen Kühlkanals kann die, den Verdichter-Spiralkanal durchströmende komprimierte Luft intensiv gekühlt werden, wodurch die Ladeluft den Verdichter mit geringerer Temperatur verlässt und entsprechend kleiner dimensionierte nachgeschaltete Ladeluftkühler anwendbar sind. Darüber hinaus ist die Verdichterantriebsleistung für gleichen Ladedruck reduziert, so dass sich ein besserer Gesamtwirkungsgrad der Brennkraftmaschine ergibt.According to the The characterizing part of claim 1 is in a surrounding a compressor spiral channel Boundary wall of a spiral housing a cooling channel provided by a cooling fluid, such as cooling water from a low-temperature cooling circuit, flows through is. By means of the spiral-side cooling channel can, the Compressor spiral channel flowing compressed air be intensively cooled, whereby the charge air the compressor leaves at a lower temperature and correspondingly smaller dimensioned downstream intercooler applicable are. In addition, the compressor drive power reduced for the same boost pressure, so that a better Overall efficiency of the internal combustion engine results.
Für eine intensive Kühlung der den Verdichter-Spiralkanal durchströmten komprimierten Luft ist es von Vorteil, wenn der spiralgehäuseseitige Kühlkanal den Spiralkanal C-förmig umschließt. Für einen günstigen sowie in Umfangsrichtung gleichmäßig guten Wärmeübergang kann die den Spiralkanal zugewandte Innenwandung des Kühlkanals im Wesentlichen eine geringe, konstante Wandstärke aufweisen. Die Innenwandung des Kühlkanals kann darüber hinaus aus einem besonders leitfähigen Material gefertigt sein.For intensive cooling of the compressor spiral channel flowed through compressed air, it is advantageous if the spiral housing side Cooling channel surrounds the spiral channel C-shaped. For a cheap as well as circumferentially evenly Good heat transfer can the spiral channel facing Inner wall of the cooling channel essentially a small, have constant wall thickness. The inner wall of the cooling channel can also be made of a particularly conductive Be made of material.
Zur weiteren Steigerung der Kühlung kann zumindest ein weiterer Kühlkanal in den, das Verdichterrad axial begrenzenden Wänden des Verdichterradgehäuses vorgesehen sein. Dadurch reduziert sich die thermische Belastung des Verdichterrads, so dass kostengünstigere Werkstoffe für das Verdichterrad und das Verdichterradgehäuse verwendet werden können.to further increase in cooling can be at least one more Cooling channel in the, the compressor wheel axially limiting Be provided walls of Verdichterradgehäuses. This reduces the thermal load of the compressor wheel, so that cheaper materials for the compressor wheel and the compressor wheel housing can be used.
Für den Fall, dass sowohl im Spiralgehäuse als auch im Verdichterradgehäuse jeweils ein Kühlkanal vorgesehen ist, können diese – strömungstechnisch bevorzugt – unmittelbar miteinander verbunden werden. Besonders bevorzugt ist es aus strömungstechnischer Sicht, wenn der verdichterradseitige Kühlkanal ohne besonderen Übergangsbereich einstückig an den spiralseitigen Kühlkanal anschließt. In diesem Zusammenhang ist es fertigungstechnisch bevorzugt, wenn das Verdichterradgehäuse und das Spiralgehäuse im Wesentlichen materialeinheitlich und einstückig ausgebildet sind.For the case that both in the volute casing and in the Verdichterradgehäuse each a cooling channel is provided, they can - fluidically preferably - be connected directly to each other. Especially it is preferred from a fluidic point of view, if the Compressor-wheel-side cooling channel without special transition area integrally connected to the spiral-side cooling channel. In this context, it is preferred manufacturing technology, if the compressor wheel housing and the volute casing essentially formed of the same material and in one piece are.
Eine besonders wirkungsvolle Kühlung der zu verdichtenden Luft wird erreicht, wenn im Verdichterradgehäuse sowohl in dessen Vorderwand als auch in dessen Rückwand ein Kühlkanal vorgesehen ist. Die beiden Kühlkanäle des Verdichterradgehäuses können dabei strömungstechnisch günstig über den spiralseitigen Kühlkanal miteinander strömungstechnisch in Verbindung sein.A particularly effective cooling of the air to be compressed is achieved when in Verdichterradgehäuse both in the Front wall as well as in the rear wall, a cooling channel is provided. The two cooling channels of the compressor wheel housing can thereby flow favorable over the spiral-side cooling channel with each other fluidically be in touch.
Für eine gleichmäßige Durchströmung kann der Kühlkanal im Querschnitt im Wesentlichen von konstanter Breite sein. Der spiralseitige Kühlkanal und/oder der zumindest eine verdichterradseitige Kühlkanal können sich dabei bevorzugt ringförmig geschlossen um die Längsachse des Strömungsverdichters erstrecken.For a uniform flow, the cooling channel in cross-section may be substantially of constant width. The spiral-side cooling channel and / or the at least one compressor-wheel-side cooling channel can preferably extend in an annular manner around the longitudinal axis of the flow compressor.
Nachfolgend ist ein Ausführungsbeispiel der Erfindung anhand der beigefügten Figur beschrieben, in der ein Radialverdichter eines Abgasturboladers in einer Halbschnittansicht teilweise dargestellt ist. Die in der Figur nicht dargestellte untere Hälfte des Abgasturboladers ist im Wesentlichen spiegelsymmetrisch zur oberen Hälfte ausgeführt.following is an embodiment of the invention with reference to the accompanying Figure described, in which a radial compressor of an exhaust gas turbocharger partially shown in a half-sectional view.
