Description
Die Erfindung betrifft einen mechanisch angetriebenen Kompressor für eine Brennkraftmaschine nach dem Oberbegriff des Anspruches 1.The The invention relates to a mechanically driven compressor for an internal combustion engine according to the preamble of claim 1.
Aus
der Druckschrift
Grundsätzlich besteht
bei derartigen Kompressoren das Problem, dass durch die Verdichtung der
Ansaugluft Wärme
abgegeben wird, die je nach Betriebszustand des Kompressors auf
Grund der Wärmedehnung
der Werkstoffe zu einer Spaltbildung führen kann, was Fehlluftströme mit einhergehenden Verlustleistungen
und einer Minderung des Verdichtungswirkungsgrades zur Folge haben
kann. Zwar ist beim Kompressor der
Der Erfindung liegt das Problem zu Grunde, einen mechanisch angetriebenen Kompressor mit hohem Wirkungsgrad und geringer Schallabstrahlung anzugeben.Of the Invention is based on the problem, a mechanically driven Compressor with high efficiency and low sound radiation specify.
Dieses Problem wird erfindungsgemäß mit den Merkmalen des Anspruches 1 gelöst.This Problem is inventively with the Characteristics of claim 1 solved.
In die Wandung des Gehäuses des neuartigen Kompressors ist ein Zwischenraum eingebracht, welcher von Kühlmittel durchströmt wird. Dadurch wird zum einen eine permanente Kühlung sowohl der Bauteile des Kompressors als auch der angesaugten und der komprimierten Luft erreicht. Zum andern wird auch der im Kompressor insbesondere während des Verdichtungsprozesses erzeugte Schall gedämpft und dadurch die Schallausbreitung, insbesondere über die Ladeluftrohre der Brennkraftmaschine, stark vermindert bzw. vollständig unterbunden.In the wall of the housing of the novel compressor, a gap is introduced, which of coolant flows through becomes. As a result, on the one hand, a permanent cooling of both the components of Compressor as well as the sucked and the compressed air reached. On the other hand, the compressor in the particular during the compression process sound generated and muffled characterized the sound propagation, in particular via the charge air pipes of the internal combustion engine, greatly diminished or complete prevented.
Die Kühlung führt zu einem konstanteren Temperaturniveau des Kompressors, so dass dieser auf einen Betrieb im Bereich einer vorgegebenen Betriebstemperatur ausgelegt werden kann, wobei im Vergleich zum Stand der Technik erheblich kleinere Temperaturschwankungen zu erwarten sind. Das geringere Schwankungsniveau der Temperatur mindert die Gefahr wärmebedingter Ausdehnungen und Spaltbildungen, wodurch Fehlluftströme insbesondere zwischen der Druck- und der Ansaugseite des Kompressors weitgehend vermieden werden und der Kompressorwirkungsgrad erhöht ist.The cooling leads to a more constant temperature level of the compressor, so this on designed operation in the range of a predetermined operating temperature can be, compared to the prior art considerably smaller temperature fluctuations are to be expected. The lower one Fluctuation of the temperature reduces the risk of heat-related Expansions and fissures, whereby Fehuftuftströme in particular between the pressure and the suction side of the compressor largely be avoided and the compressor efficiency is increased.
Weiterhin ist vorteilhaft, dass der verdichteten Luft während des Verdichtungsprozesses Wärme entzogen wird, was zur Folge hat, dass der Verdichtungsprozess anstelle eines isentropen Verlaufes zunehmend in Richtung eines isothermischen Verlaufes verschoben wird. Dadurch sinkt die zwischen den festliegenden Anfangs- und Enddrücken aufzuwendende Arbeit der Verdichtung gegenüber dem adiabaten Fall.Farther It is advantageous that the compressed air during the compression process Heat deprived which results in the compression process instead of a isentropic course increasingly towards isothermal History is moved. This reduces the between the fixed Start and end press work to be done on compression compared to the adiabatic case.
In einer bevorzugten Ausführung ist vorgesehen, dass das Gehäuse doppelwandig ausgeführt ist, wobei der das Kühlmittel aufnehmende Zwischenraum zwischen der Innenwand und der Außenwand des Gehäuses gebildet ist. In dieser Ausführung kann die den Kompressorinnenraum einschließende Kühlfläche maximiert werden, so dass auch die Kühlleistung ein Maximum einnimmt und darüber hinaus auch eine optimale Schalldämpfung gegeben ist.In a preferred embodiment is provided that the housing double-walled where is the coolant receiving space between the inner wall and the outer wall of the housing is formed. In this version For example, the cooling surface enclosing the compressor interior can be maximized so that also the cooling capacity takes a maximum and above In addition, an optimal sound attenuation is given.
Die in die Wandung des Gehäuses integrierte Kühlung bietet zusätzlich den Vorteil einer besonders raumsparenden, kompakten Bauform.The in the wall of the housing integrated cooling offers additional the advantage of a particularly space-saving, compact design.
In das Gehäuse des Kompressors ist ein Ladeluftkühler integriert, der vom Kühlmittel des Kompressors durchströmt wird. In dieser Ausführung übernimmt das Kühlmittel sowohl die Kühlung über das Gehäuse des Kompressors als auch über den in das Gehäuse integrierten Ladeluftkühler. Die Integration des Ladeluftkühlers in das Gehäuse verringert erheblich den Raumbedarf von Kompressor und Ladeluftkühler und vereinfacht darüber hinaus auch die Montage des zu einer Baueinheit zusammengefassten Aggregates. Die gemeinsame Durchströmung von Gehäuse und Ladeluftkühler mit Kühlmittel vereinfacht die konstruktive Ausfüh rung des Bauteils, da im Bauteil lediglich ein gemeinsamer Kühlmitteleintritt und ein gemeinsamer Kühlmittelaustritt vorgesehen sein muss.In the housing the compressor has an intercooler integrated with the coolant flows through the compressor becomes. In this execution takes over the coolant both the cooling over the casing of the compressor as well into the case integrated intercooler. The integration of the intercooler in the case significantly reduces the space required by the compressor and intercooler and simplified about it In addition, the assembly of summarized into a unit Aggregates. The common flow of housing and Intercooler with coolant simplifies the constructive Ausfüh tion of the component, as in the component only a common coolant inlet and a common coolant outlet must be provided.
Gemäß einer weiteren vorteilhaften Ausführung besteht die Verdichtereinrichtung (insbesondere der Rotor) aus einem Werkstoff mit einem geringen Ausdehnungskoeffizienten, um Wärmedehnungen weiter zu reduzieren.According to one further advantageous embodiment the compressor device (in particular the rotor) consists of a Material with a low coefficient of expansion to thermal expansion on to reduce.
