Description
Die Erfindung bezieht sich auf ein Kühlsystem gemäß dem Oberbegriff des Anspruches 1 für eine in ein Kraftfahrzeug eingebaute Brennkraftmaschine.The invention relates to a cooling system according to the preamble of
In der
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.Such a cooling system is quite suitable using simple, inexpensive means to ensure sufficient heating of the passenger compartment in addition to sufficient cooling of the engine, but can hardly cause a directed to the respective operating condition or the respective driving speed of the motor vehicle cooling the engine.
Aus 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.The invention is based on the above-indicated prior art, the object of providing a cooling system for a built in a motor vehicle internal combustion engine, which ensures the lowest possible effort, especially on switching means, optimal cooling of the engine at each power demand or speed of the motor vehicle.
Diese Aufgabe wird erfindungsgemäß durch die im Patentanspruch 1 angegebenen Merkmale gelöst. Vorteilhafte Weiterbildungen und zweckmäßige Ausgestaltungsformen sind in den Unteransprüchen angegeben.This object is achieved by the features specified in
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.The advantage achieved in particular with the invention is seen in the fact that, despite low circuit complexity at different operating conditions or driving conditions of the motor vehicle optimum cooling of the internal combustion engine of the motor vehicle is achieved. In particular, the use of cooling air blowers is required only for the two of the sufficient cooling of the internal combustion engine with low power requirement or low driving speeds, mainly provided in city traffic lateral air / water heat exchanger of the cooling system, while the middle, the cooling of the engine at higher speeds associated air / water heat exchanger due to the then existing ram air flow rate requires no cooling fan. However, in order to rule out overheating or boiling of the cooling water during operation of the motor vehicle with low power demand on the internal combustion engine and simultaneously at low driving speeds at which no or no appreciable ram air flow through the middle radiator is present, it is further provided that in the cooling water flow to the middle air / water heat exchanger, a throttle valve is turned on, which prevents the cooling water flow at low power requirements and / or low speeds.
Die Erfindung ist in der nachfolgenden Beispielsbeschreibung anhand eines in der Zeichnung dargestellten Ausführungsbeispieles im Einzelnen beschrieben.The invention is described in detail in the following example description with reference to an embodiment shown in the drawing.
