Abstract
Description
Die Erfindung bezieht sich auf ein Kühlsystem, insbesondere für ein Kraftfahrzeug, nach dem Oberbegriff des Patentanspruchs 1. Derartige Kühlsysteme werden beispielsweise für Kraftfahrzeugmotoren mit Turbolader eingesetzt, um mit dem Aggregatkühlkreislauf den Motor und mit dem Zusatzkühlkreislauf indirekt die Ladeluft zu kühlen, die für den Motor vom Turbolader bereitgestellt wird.

Eine solche Nutzanwendung eines Kühlsystems zur Motorkühlung und indirekten Ladeluftkühlung bei einem Kraftfahrzeug ist in dem Zeitschriftenaufsatz "Kühlmittelgekühlte Ladeluftkühler für Kraftfahrzeug-Motoren", MTZ Motortechnische Zeitschrift 61(2000)9, Seiten 592 bis 599 beschrieben. Beim dortigen System sind Mittel zur Regulierung des Kühlmittelflusses über den Hauptkühlmittelkühler und Mittel zur Kühlmitteltemperaturerfassung als integrale Bestandteile eines Thermostatelementes realisiert, das vor dem Hauptkühlmittelkühler an einer Abzweigstelle einer den Hauptkühlmittelkühler umgehenden Bypassleitung angeordnet ist. Der Zusatzkühlkreislauf mit dem Zusatzkühlmittelkühler, in diesem Anwendungsfall als Niedertemperaturkühlmittelkühler bezeichnet, zweigt zwischen dem Motor und dem Thermostaten vom Aggregatkühlkreislauf ab, wobei vor dem Niedertemperaturkühlmittelkühler ein Regelventil angeordnet ist. Nach Durchtritt durch den Niedertemperatur kühlmittelkühler gelangt das über den Aggregatkühlkreislauf geführte Kühlmittel zu einem Ladeluft/Kühlmittel-Kühler, um dann an einer zwischen dem Hauptkühlmittelkühler und einer Kühlmittelförderpumpe gelegenen Einkoppelstelle wieder zum Aggregatkühlkreislauf zurückgeführt zu werden. An dieser Einkoppelstelle mündet auch die den Hauptkühlmittelkühler umgehende Bypassleitung ein.A such useful application of a cooling system for engine cooling and indirect intercooling in a motor vehicle is in the journal article "Coolant-cooled intercooler for motor vehicle engines", MTZ Motortechnische Journal 61 (2000) 9, pages 592 to 599 described.

Der Erfindung liegt als technisches Problem die Bereitstellung eines Kühlsystems der eingangs genannten Art zugrunde, das zur wirksamen und komfortablen Kühlung eines Hauptaggregats und von mehreren Zusatzaggregaten bzw. Zusatzmedien geeignet ist.Of the Invention is the technical problem of providing a cooling system of the type mentioned, which is effective and comfortable cooling a main unit and several additional aggregates or additional media suitable is.
Die Erfindung löst dieses Problem durch die Bereitstellung eines Kühlsystems mit den Merkmalen des Patentanspruchs 1.The Invention solves this problem by providing a cooling system with the characteristics of Patent claim 1.
Vorteilhafte Weiterbildungen der Erfindung sind in den abhängigen Ansprüchen angegeben.advantageous Further developments of the invention are specified in the dependent claims.
Erfindungsgemäß ist der Zusatzkühlkreislauf in mindestens zwei parallele Zusatzkühlzweige mit unterschiedlichen vom Zusatzkühlmittelkühler erzeugten Temperaturniveaus aufgeteilt, welche jeweils mindestens ein Zusatzmedium und/oder Zusatzag gregat kühlen. Dadurch ist es möglich, ein wärmeerzeugendes Aggregat und verschiedene Zusatzaggregate und/oder Zusatzmedien mit unterschiedlichen Temperaturniveaus durch das gleiche Kühlmittel zu kühlen, ohne zusätzliche Kühler zur Kühlung des Kühlmittels zu benötigen. Zur Kühlmittelkühlung werden zwei Baugruppen genutzt, nämlich der Hauptkühlmittelkühler und der Zusatzkühlmittelkühler mit seinen mehreren Auslässen für verschiedene Temperaturniveaus. Es lässt sich eine optimale Anpassung an die Erfordernisse, wie ausreichende Druckverhältnisse und Volumenströme, erzielen. Durch die Auskopplung des Zusatzkühlkreislaufs zwischen der Kühlmittelförderpumpe und dem wärmeerzeugenden Aggregat wirkt sich in vorteilhafter Weise der Druckabfall am wärmeerzeugenden Aggregat nicht auf das für den Zusatzkühlkreislauf erzielbare Druckgefälle aus. Zudem braucht der Zusatzkühlmittelkühler nur auf eine ähnliche Druckbelastung wie der Hauptkühlmittelkühler ausgelegt werden.According to the invention, the additional cooling circuit is divided into at least two parallel auxiliary cooling branches with different temperature levels generated by the auxiliary coolant cooler, each of which cools at least one additional medium and / or additional gas. This makes it possible to cool a heat-generating unit and various additional units and / or additional media with different temperature levels by the same coolant, without additional cooler for To require cooling of the coolant. For coolant cooling two assemblies are used, namely the main coolant radiator and the auxiliary coolant radiator with its multiple outlets for different temperature levels. It can be an optimal adaptation to the requirements, such as sufficient pressure conditions and flow rates achieve. By decoupling the additional cooling circuit between the coolant supply pump and the heat-generating unit, the pressure drop on the heat-generating unit does not have an advantageous effect on the pressure gradient that can be achieved for the additional cooling circuit. In addition, the additional coolant cooler only needs to be designed for a similar pressure load as the main coolant cooler.
In Ausgestaltung des Kühlsystems ist der Zusatzkühlmittelkühler als mehrflutiger Wärmeübertrager ausgeführt, wobei die Anzahl der Fluten mindestens so groß wie die Anzahl von Auslässen bzw. Zusatzkühlzweigen ist. Durch die Entnahme des Kühlmittels nach Durchlauf einer oder mehrerer Fluten des Zusatzkühlmittelkühlers steht das Kühlmittel mit einem reduzierten ersten Temperaturniveau für die Kühlung von Zusatzaggregaten und/oder Zusatzmedien zur Verfügung. Nach mindestens einer weiteren Flut wird das Kühlmittel zur Kühlung von weiteren Zusatzaggregaten und/oder Zusatzmedien, beispielsweise zur Ladeluftkühlung, weiter auf ein niedrigeres zweites Temperaturniveau abgekühlt. Dadurch kann die Größe des Zusatzkühlmittelkühlers gegenüber mehreren Kühlmittelkühlern mit nur einem Auslass reduziert werden.In Design of the cooling system is the auxiliary coolant cooler as multi-flow heat exchanger executed wherein the number of floods at least as large as the number of outlets or Additional cooling branches is. By removing the coolant after passing through one or more floods of the auxiliary coolant cooler the coolant with a reduced first temperature level for the cooling of additional units and / or additional media available. After at least one further flood, the coolant for cooling other additional aggregates and / or additional media, for example for intercooling, further cooled to a lower second temperature level. Thereby The size of the auxiliary coolant cooler over several Coolant coolers with only one outlet can be reduced.
In weiterer Ausgestaltung des Kühlsystems sind Mittel zur Kühlmitteltemperaturerfassung im Aggregatkühlkreislauf und/oder in mindestens einem Zusatzkühlzweig vorgesehen. Durch die Erfassung der Kühlmitteltemperatur an verschiedenen Stellen innerhalb der vorhandenen Kühlkreisläufe können die Kühlmittelförderpumpe und ein optionales Thermostatventil an die variierenden Anforderungen der Kühlkreisläufe während des Betriebs angepasst werden.In further embodiment of the cooling system are Coolant temperature sensing means in the unit cooling circuit and / or provided in at least one additional cooling branch. By the Detection of the coolant temperature At various points within the existing cooling circuits, the Coolant pump and an optional thermostatic valve to meet the varying needs the cooling circuits during the To be adjusted.
In weiterer Ausgestaltung des Kühlsystems sind Mittel zur Regulierung des Kühlmittelflusses über den Hauptkühlmittelkühler in Abhängigkeit von der erfassten Kühlmitteltemperatur vorgesehen, welche integraler Bestandteil eines Thermostatelementes sind, das an der Einkoppelstelle angeordnet ist. Dadurch bestimmt das Thermostatelement den Kühlmittelfluss über den Aggregatkühlkreislauf und den Zusatzkühlkreislauf in Abhängigkeit auch von der austrittsseitigen Kühlmitteltemperatur des Zusatzkreislaufs.In further embodiment of the cooling system are Means for regulating the flow of coolant over the Main coolant cooler in dependence from the detected coolant temperature provided, which integral part of a thermostatic element are, which is arranged at the coupling point. Determined by it the thermostatic element the coolant flow over the Physical cooling circuit and the additional cooling circuit dependent on also from the exit-side coolant temperature of the additional circuit.
In weiterer Ausgestaltung des Kühlsystems ist ein Kühlmittelausgleichsbehälter vorhanden, der dem Aggregatkühlkreislauf und/oder mindestens einem der Zusatzkühlzweige zugeordnet ist, d.h. über je wenigstens eine Ausgleichsleitung mit dem Aggregatkühlkreislauf und/oder mindestens einem der Zusatzkühlzweige gekoppelt ist. Dadurch lässt sich auf einfache Weise ein Druck- und/oder Volumenausgleich in den Kühlkreisläufen herbeiführen.In Another embodiment of the cooling system is a coolant expansion tank available, the aggregate cooling circuit and / or associated with at least one of the auxiliary cooling branches, i. at least ever a compensation line with the unit cooling circuit and / or at least one of the additional cooling branches is coupled. By doing so leaves in a simple way, a pressure and / or volume compensation in bring the cooling circuits.
Das Kühlsystem lässt sich zur Kühlung eines Kraftfahrzeugmotors, zur indirekten Kühlung von Ladeluft für den Motor und zur Kühlung von weiteren Zusatzaggregaten, wie beispielsweise einem Abgasturbolader und/oder einer Elektronikkomponente und/oder einem Getriebe, sowie von Zusatzmedien, wie bei spielsweise Kraftstoff und/oder rückgeführtes Abgas und/oder Getriebeöl, verwenden.The cooling system let yourself for cooling a motor vehicle engine, for the indirect cooling of charge air for the engine and for cooling of additional accessories, such as an exhaust gas turbocharger and / or an electronic component and / or a transmission, as well as of additional media, such as fuel and / or recirculated exhaust gas and / or gear oil, use.
