Die Erfindung betrifft ein Kühlsystem für einen Verbrennungmotor eines Kraftfahrzeuges mit einem Kühlmittelkreislauf.The The invention relates to a cooling system for one Combustion engine of a motor vehicle with a coolant circuit.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein Kühlsystem für ein Kraftfahrzeug zu schaffen, das einen hohen Wirkungsgrad bei einfachem Aufbau und begrenzten Bauraumverhältnissen besitzt.Of the present invention is based on the object, a cooling system for a To create a motor vehicle that has a high efficiency with simple Structure and limited space conditions owns.
Erfindungsgemäß wird diese Aufgabe durch die im Anspruch 1 genannten Merkmale gelöst.According to the invention this Problem solved by the features mentioned in claim 1.
Erfindungsgemäß liegt nun der Zusatzkühler zusätzlich zu dem Kühlmittelkühler im Hauptkreislauf des Kühlmittelstromes, jedoch räumlich getrennt davon. Da jeder Kühler mit Frischluft versorgt wird, kann auch jeder Kühler seine maximale Wirkung entfalten. Durch die gemeinsame Verwendung des Kühllüfters wird jedoch Sekundärenergie eingespart, da kein Zusatzgebläse erforderlich ist. Gleichzeitig wird dabei auch eine raumsparende Lösung geschaffen, da der Zusatzkühler nicht im Bereich des Hauptkühlers angeordnet ist und z.B. bei einem Nutzfahrzeug mit der Vorbauklappe des Kraftfahrzeuges verbunden sein kann.According to the invention now the auxiliary cooler in addition to the coolant cooler in the Main circuit of the coolant flow, but spatially separate from it. Because every cooler supplied with fresh air, each cooler can its maximum effect unfold. However, the combined use of the cooling fan becomes secondary energy saved, because no additional blower is required. At the same time, it will also save space solution created because the auxiliary cooler not in the area of the main cooler is arranged and e.g. in a commercial vehicle with the front flap of the motor vehicle can be connected.
Durch eine Anordnung des Zusatzkühlers im Fahrzeug-Frontgitter erfolgt eine kühlluftseitige Beaufschla gung durch Staudruck (Fahrgeschwindigkeit), z.B. auch bei abgeschaltetem Kühllüfter (Leerlaufdrehzahl bzw. Schleppdrehzahl) oder alternativ additiv, insbesondere bei niedriger Fahrgeschwindigkeit, wie z.B. Betriebszustand unter Vollast, unter Einbeziehung des Kühllüfters und dessen betriebszustandabhängigen, über die Motortemperatur gesteuertem Regel- bzw. Zuschalt- und Abschaltverhalten.By an arrangement of the additional cooler in the vehicle front grille there is a cool air side Impact by dynamic pressure (driving speed), e.g. also with the cooling fan switched off (idling speed or towing speed) or alternatively additive, in particular at low travel speed, e.g. Operating condition under full load, including the cooling fan and whose operating state dependent, over the Motor temperature controlled control or connection and shutdown.
Mit der erfindungsgemäßen Lösung wird eine deutliche Steigerung der Kühlkapazität, insbesondere für Motoren mit erhöhten Immissionsanforderungen, erreicht.With the solution according to the invention becomes a significant increase in cooling capacity, in particular for engines with increased Immissions requirements, achieved.
Erfindungsgemäß erfolgt nunmehr eine kühlluftseitige zusätzliche Zwangsbeaufschlagung über den Kühllüfter bei einer kühlmittelseitigen Parallelschaltung mit einer Hauptkühlanlage bzw. eines Hauptkühlsystem oder auch über eine kühlmitteltemperaturabhängige thermostatische Zusteuerung.According to the invention now a cool air side additional Compulsion over the Cooling fan at a coolant side Parallel connection with a main cooling system or a main cooling system or over a coolant temperature dependent thermostatic Close control.
In einer alternativen Lösung kann der Zusatzkühler auch zur Kühlung der Ladeluft durch einen entsprechenden Wärmetauscher verwendet werden. Vorzugsweise wird dabei eine Niedertemperaturkreislaufkühlung erreicht. Für diesen Zweck kann der Zusatzkühler mit entsprechend reduzierter Kühlmediummenge beaufschlagt für die Abgasrückführung bzw. für eine Ladeluft/Kühlmittelkühlung eingesetzt werden.In an alternative solution can the auxiliary cooler also for cooling the charge air can be used by a corresponding heat exchanger. Preferably while a low-temperature circuit cooling is achieved. For this Purpose can be the auxiliary cooler with correspondingly reduced amount of cooling medium charged for the exhaust gas recirculation or for one Charge air / coolant cooling can be used.
