Abstract
Description
Die Erfindung bezieht sich auf ein Kühlsystem gemäß dem Oberbegriff des Anspruches 1 für eine in ein Kraftfahrzeug eingebaute Brennkraftmaschine.The The invention relates to a cooling system according to the generic term of claim 1 for a built in a motor vehicle internal combustion engine.
Aus
der
Ein solches Kühlsystem ist durchaus geeignet unter Einsatz einfacher, wenig aufwendiger Mittel neben einer ausreichenden Kühlung der Brennkraftmaschine auch eine ausreichende Beheizung des Fahrgastraumes sicher zu stellen, kann aber schwerlich eine auf den jeweiligen Betriebszustand bzw. die jeweilige Fahrgeschwindigkeit des Kraftfahrzeuges ausgerichtete Kühlung der Brennkraftmaschine bewirken.One such cooling system is quite suitable using simple, less expensive Means in addition to a sufficient cooling of the internal combustion engine also to ensure sufficient heating of the passenger compartment, but can hardly on the respective operating condition or the respective driving speed of the motor vehicle aligned cooling cause the internal combustion engine.

der
Der Erfindung liegt ausgehend von dem vorstehend aufgezeigten Stand der Technik die Aufgabe zugrunde ein Kühlsystem für eine in ein Kraftfahrzeug eingebaute Brennkraftmaschine anzugeben, welches bei geringstmöglichem Aufwand, insbesondere an Schaltmitteln, eine optimale Kühlung der Brennkraftmaschine bei jeder Leistungsanforderung bzw. Fahrgeschwindigkeit des Kraftfahrzeuges gewährleistet.Of the Invention is based on the above-indicated state The technique is based on the task of a cooling system for a in a motor vehicle specify internal combustion engine, which at the lowest possible Effort, especially on switching means, optimal cooling of the engine at every power requirement or driving speed of the motor vehicle guaranteed.
Diese Aufgabe wird erfindungsgemäß durch die im Patentanspruch 1 angegebenen Merkmale gelöst. Vorteilhafte Weiterbildungen und zweckmäßige Ausgestaltungsformen sind in den Unteransprüchen angegeben.These The object is achieved by the achieved in claim 1 features. Advantageous developments and expedient embodiments are given in the subclaims.
Der insbesondere mit der Erfindung erzielte Vorteil wird darin gesehen, daß trotz geringem Schaltungsaufwand bei unterschiedlichen Betriebsbedingungen bzw. Fahrbedingungen des Kraftfahrzeuges eine optimale Kühlung der Brennkraftmaschine des Kraftfahrzeuges erreicht wird. Insbesondere ist lediglich für die beiden der ausreichenden Kühlung der Brennkraftmaschine bei geringer Leistungsanforderung bzw. geringen Fahrgeschwindigkeiten, hauptsächlich im Stadtverkehr, vorgesehenen seitlichen Luft Wasser-Wärmetauscher des Kühlsystemes der Einsatz von Kühlluftgebläsen erforderlich, während der mittlere, der Kühlung der Brennkraftmaschine bei höheren Fahrgeschwindigkeiten zugeordnete Luft-/-Wasser-Wärmetauscher infolge des dann vorhandenen Stauluftdurchsatzes keines Kühlgebläses bedarf. Um aber während des Betriebes des Kraftfahrzeuges bei niedriger Leistungsanforderung an die Brennkraftmaschine und gleichzeitig bei niedrigen Fahrgeschwindigkeiten, bei denen kein oder kein nennenswerter Stauluftdurchsatz durch den mittleren Kühler gegeben ist, eine Überhitzung bzw. ein Kochen des Kühlwassers auszuschließen ist, ist erfindungsgemäß weiterhin vorgesehen, daß in den Kühlwasservorlauf zum mittleren Luft-/-Wasser-Wärmetauscher ein Drosselventil eingeschaltet ist, welches den Kühlwasservorlauf bei geringen Leistungsanforderungen und/oder geringen Fahrgeschwindigkeiten unterbindet.Of the particular advantage achieved with the invention is seen therein that despite low circuit complexity under different operating conditions or driving conditions of the motor vehicle optimal cooling of the Internal combustion engine of the motor vehicle is achieved. Especially is only for the two of the sufficient cooling the internal combustion engine with low power requirement or low Driving speeds, mainly in city traffic, provided lateral air water heat exchanger of the cooling system the use of cooling air blowers required during the medium, of cooling the internal combustion engine at higher Travel speeds assigned air / water heat exchanger requires no cooling fan due to the then existing ram air flow rate. But during the operation of the motor vehicle at low power requirement to the internal combustion engine and at the same time at low driving speeds, where no or no significant ram air flow through the middle cooler is given, overheating or a boiling of the cooling water excluded is still according to the invention provided that in the cooling water supply to the middle air / water heat exchanger a throttle valve is turned on, which is the cooling water flow at low power requirements and / or low speeds prevented.
Die Erfindung ist in der nachfolgenden Beispielsbeschreibung anhand eines in der Zeichnung dargestellten Ausführungsbeispieles im Einzelnen beschrieben.The Invention is illustrated in the following example description an embodiment shown in the drawing described in detail.
