Ferner sind Kraftfahrzeugkühlvorrichtungen bekannt, die einen Ladeluftkühlmittelkreislauf mit einer elektrischen Pumpe und einen vom Ladeluftkühlmittelkreislauf getrennten Motorkühlkreislauf mit einer separaten elektrischen Pumpe zur Nachlaufkühlung des Motors umfassen.Further are motor vehicle cooling devices known the one charge air coolant circuit with an electric pump and one of the charge air coolant circuit separate engine cooling circuit with a separate electric pump for the aftercooling of the Motors include.
Der Erfindung liegt die Aufgabe zugrunde, eine Kraftfahrzeugkühlvorrichtung bereitzustellen, in der eine zum Antreiben eines Ladeluftkühlmittelkreislaufs vorgesehene Pumpe vorteilhaft doppelt nutzbar ist.Of the Invention is based on the object, a motor vehicle cooling device in which one for driving a charge air coolant circuit provided pump is advantageously used twice.
Die Erfindung geht aus von einer Kraftfahrzeugkühlvorrichtung mit einem Motorkühlkreislauf und einer Pumpe, die während einer Betriebsphase eines vom Motorkühlkreislauf gekühlten Mo tors zum Antreiben eines Ladeluftkühlmittelkreislaufs vorgesehen ist.The The invention is based on a motor vehicle cooling device with an engine cooling circuit and a pump while an operating phase of a motor cooled by the engine cooling circuit Mo gate for driving a charge air coolant circuit is provided.
Es wird vorgeschlagen, dass die Pumpe zum Antrieb des Motorkühlkreislaufs in einer Nachlaufkühlphase vorgesehen ist. Dadurch kann die Pumpe vorteilhaft in den unterschiedlichen Betriebsphasen unterschiedlich nutzbar sein. Auf eine separate Pumpe zum Antrieb des Motorkühlkreislaufs in der Nachlaufkühlphase kann vorteilhaft verzichtet werden. Dadurch können Bauraum und Kosten eingespart werden.It It is suggested that the pump be used to drive the engine cooling circuit in a follow-up cooling phase is provided. This allows the pump advantageous in the different Operating phases can be used differently. On a separate pump for driving the engine cooling circuit in the aftercooling phase can be advantageously dispensed with. This saves space and costs become.
Als Nachlaufkühlphase soll eine Phase nach einem Abschalten des Motors bezeichnet werden, in der der Motorkühlkreislauf zum Vermeiden eines Überkochens einer Kühlflüssigkeit weiter angetrieben wird. Dabei wird Wärme aus der Kühlflüssigkeit über einen Wärmetauscher an einen vorteilhaft von einem Gebläse angetriebenen Luftstrom abgegeben, bis beispielsweise eine Temperatur des Motors einen vorgegebenen Wert unterschritten hat oder bis beispielsweise eine vorgegebene Nachlaufzeit abgelaufen ist. Entsprechend ist eine Betriebsphase jede Phase, in der der Motor Wärme erzeugt. Der Motor kann beispielsweise als Brennkraftmaschine mit Turbolader oder mit Kompressor ausgebildet sein. Der Ladeluftkühlmittelkreislauf und der Motorkühlkreislauf können als Kühlmittel Wasser oder eine andere, dem Fachmann als sinnvoll erscheinende Kühlflüssigkeit führen. Unter „vorgesehen" soll in diesem Zusammenhang auch „ausgelegt" und „ausgestattet" verstanden werden.When Trailing cooling phase should be called a phase after a shutdown of the engine, in the engine cooling circuit to avoid overcooking a cooling liquid is driven further. This heat from the coolant over a heat exchangers to an advantageous powered by a fan airflow delivered until, for example, a temperature of the engine a predetermined Value has fallen below or until, for example, a predetermined After-run time has expired. Accordingly, an operating phase every phase in which the engine heat generated. The engine can be used as an internal combustion engine, for example Turbocharger or be designed with a compressor. The charge air coolant circuit and the engine cooling circuit can as a coolant Water or another, the expert appears useful coolant to lead. Under "provided" should in this context also understood as "designed" and "equipped".
In einer Ausgestaltung der Erfindung wird vorgeschlagen, dass der Ladeluftkühlmittelkreislauf von einer Verzweigung des Motorkühlkreislaufs gebildet ist. Dadurch können beide Kreisläufe zumindest in einem Teilbereich vom gleichen Kühlmittelstrom gebildet sein, wodurch weitere Bauraum- und Kosteneinsparungspotenziale erschlossen werden können.In An embodiment of the invention is proposed that the charge air coolant circuit of a branch of the engine cooling circuit is formed. Thereby can both circuits be formed at least in a partial area of the same coolant flow, thereby opening up further space and cost saving potential can be.
Ferner wird vorgeschlagen, dass der Motorkühlkreislauf und der Ladeluftkühlmittelkreislauf im Nachlauf in Reihe geschaltet sind. Dadurch ist ein Antrieb der Nachlauf kühlung durch eine im Ladeluftkühlmittelkreislauf angeordnete Pumpe konstruktiv einfach erreichbar.Further It is proposed that the engine cooling circuit and the charge air coolant circuit are connected in series in the wake. This is a drive of Caster cooling by a in the charge air coolant circuit arranged pump structurally easy to reach.
Umfasst die Kraftfahrzeugkühlvorrichtung eine Wasserpumpe zum Antreiben des Motorkühlkreislaufs, kann eine Dimensionierung der Pumpe vorteilhaft unabhängig von einer Soll-Fördermenge in der Betriebsphase erfolgen, die dann durch die Wasserpumpe bestimmt ist.includes the motor vehicle cooling device a Water pump for driving the engine cooling circuit, can be a sizing the pump advantageous independent from a target flow rate carried out in the operating phase, which then determined by the water pump is.
Umfasst die Kraftfahrzeugkühlvorrichtung ein Rückschlagventil zum selbsttätigen Umschalten in den Nachlaufbetrieb, ist ein sicheres Umschalten zwischen verschiedenen Verläufen der Kühlmittelströme mit geringem konstruktivem Aufwand realisierbar. Dabei kann ein sicheres Umschalten durch einen durch das Ausschalten der Wasserpumpe erzeugten Druckabfall erreicht werden, wenn das Rückschlagventil dazu vorgesehen ist, sich beim Aussetzen der Wasserpumpe durch den von der Pumpe erzeugten Druck selbsttätig zu schließen.includes the vehicle cooling device check valve to the automatic Switching to the follow-up mode, is a safe switching between different courses the coolant flows with low constructive effort feasible. This can be a safe switching by a pressure drop generated by switching off the water pump be achieved when the check valve is provided to the suspension of the water pump through the to close the pressure generated by the pump automatically.
Eine kompakte Führung der Kreisläufe kann erreicht werden, wenn der Motorkühlkreislauf und der Ladeluftkühlmittelkreislauf zumindest in einem Teilbereich zusammen geführt sind. Ferner können dadurch Wärmeverluste verringert werden.A compact leadership of the circuits can be achieved when the engine cooling circuit and the charge air coolant circuit are brought together at least in one subarea. Furthermore, it can heat loss be reduced.
Ist der Ladeluftkühlmittelkreislauf im Bereich eines Wärmetauschers vom Motorkühlkreislauf abgezweigt, kann erreicht werden, dass der Ladeluftkühlmittelkreislauf und der Motorkühlkreislauf durch den Wärmetauscher auf unterschiedliche, den Aufgaben der Kreisläufe angepasste Temperaturen kühlbar sind.is the charge air coolant circuit in the area of a heat exchanger from the engine cooling circuit diverted, it can be achieved that the charge air coolant circuit and the engine cooling circuit through the heat exchanger on different, the tasks of the circuits adapted temperatures cooled are.
Eine vorteilhaft niedere Temperatur des Ladeluftkühlmittelkreislaufs ist erreichbar, wenn der Ladeluftkühlmittelkreislauf länger im Wärmetauscher verläuft als der Motorkühlkreislauf.A advantageously low temperature of the charge air coolant circuit is achievable when the charge air coolant circuit longer in the heat exchanger runs as the engine cooling circuit.
