Description
Die Erfindung betrifft ein Verfahren zum Betrieb eines einen Kühler und eine Brennkraftmaschine verbindenden Kühlmittelkreislaufs eines Kraftfahrzeugs, insbesondere Hybridfahrzeugs, wobei mittels eines Bypassventils ein von dem Kühlmittel durchströmbarer Wärmetauscher einer elektrischen Baugruppe mit dem Kühlmittelkreislauf bedarfsweise verbunden oder von diesem getrennt wird. Weiterhin betrifft die Erfindung eine mit einem Wärmetauscher ausgestattete Einrichtung zum Beheizen eines Fahrzeuginnenraums eines Kraftfahrzeugs, insbesondere Hybridfahrzeugs, die mit einem eine Kühlmittelpumpe aufweisenden Kühlmittelkreislauf verbunden ist.The The invention relates to a method for operating a cooler and an internal combustion engine connecting coolant circuit a motor vehicle, in particular a hybrid vehicle, wherein by means of a Bypass valve one of the coolant flowed through Heat exchanger of an electrical assembly with the coolant circuit if necessary connected or separated from it. Farther The invention relates to a equipped with a heat exchanger Device for heating a vehicle interior of a motor vehicle, in particular hybrid vehicle with a coolant pump having connected coolant circuit.

gemäß der
In Fahrzeugen mit Hybridantrieb fallen in der Leistungselektronik hohe thermische Verlustleistungen an. Gleichzeitig sinkt der vom Verbrennungsmotor des Hybridantriebs an das Kühlwasser abgegebene Wärmeeintrag, wenn das Fahrzeug mit rein elektrischem Fahrbetrieb sowie im Start-Stop-Betrieb angetrieben wird.In Hybrid vehicles are high in power electronics thermal power losses. At the same time the engine of the internal combustion engine decreases the hybrid drive delivered to the cooling water heat input, if the vehicle with purely electric driving operation and in the start-stop operation is driven.
Unabhängig von dem Hybridantrieb sind auch in verbrauchsarmen Fahrzeugen, die beispielsweise mit aufgeladenen Dieselmotoren ausgerüstet sind, oftmals bereits Zusatzheizer für den Fahrgastraum im Einsatz.Independently from the hybrid drive are also available in low-consumption vehicles, the for example, are equipped with charged diesel engines, often additional heater for the passenger compartment in use.
Die Nutzung der Abwärme von elektrischen Baugruppen führt zu einer schnelleren Aufheizung des Motorkühlkreislaufs und damit zur Reduzierung des Kraftstoffverbrauchs, da eine schnellere Aufheizung des Kühlwassers mit schnellerer Motoraufheizung verbunden ist. Ferner führt die schnellere Aufheizung des Kühlwassers zu höherem Fahrgastkomfort, da die höhere Kühlwassertemperatur mehr Wärme ins Fahrzeuginnere transportieren kann.The Use of waste heat from electrical assemblies leads to a faster heating of the engine cooling circuit and thus to reduce fuel consumption, as a faster Heating the cooling water with faster engine heating connected is. Furthermore, the faster heating of the leads Cooling water to higher passenger comfort, as the higher cooling water temperature more heat can transport to the vehicle interior.

Als nachteilig erweist es sich, dass in einer Start- bzw. Kaltphase bis zu einer ausreichenden Erwärmung des Kühlmittels eine elektrische Zuheizung erforderlich ist, die zu einem erheblichen Mehrverbrauch führt.When disadvantageous it turns out that in a start or cold phase until sufficient heating of the coolant An electric heater is required, which leads to a considerable More consumption leads.
Vor diesem Hintergrund liegt der Erfindung ein verbessertes Verfahren sowie eine hierzu bestimmte Einrichtung zugrunde, mit dem Ziel, die Dauer der Kaltphase zu verringern und die ge gebenenfalls erforderliche Zuheizung einschließlich des damit verbundenen elektrischen Energieverbrauchs zu reduzieren.In front In this background, the invention is an improved method and a dedicated facility, with the aim of reduce the duration of the cold phase and, if necessary, the required Heating including the associated electrical Reduce energy consumption.
Diese Aufgabe wird gelöst mit einem Arbeitsverfahren sowie mit einer Einrichtung gemäß den Merkmalen der Patentansprüche 1 und 5. Die Unteransprüche betreffen besonders zweckmäßige Weiterbildungen der Erfindung.These Task is solved with a working method and with a device according to the features of the claims 1 and 5. The subclaims relate to particularly expedient Further developments of the invention.
Erfindungsgemäß ist also ein Verfahren vorgesehen, bei dem in einer Betriebsphase unterhalb einer vorbestimmten Kühlmitteltemperatur zumindest ein von dem Kühlmittel durchströmbarer Wärmetauscher einer Baugruppe, der eine hohe Wärmekapazität zugeordnet ist, mittels des Bypassventils von dem Kühlmitteldurchfluss getrennt wird. In überraschend einfacher Weise wird durch das erfindungsgemäße Verfahren die zum Erreichen der erforderlichen Kühlmitteltemperatur erforderliche elektrische Zuheizung dadurch auf ein Minimum beschränkt, dass in der Start- oder Kaltphase solche Baugruppen, die einen Betriebspunkt mit einer ausreichenden Wärmeabgabe noch nicht erreicht haben, von dem Kühlmittelkreislauf getrennt werden. Hierdurch wird also dem Kühlmittel des Kühlmittelkreislaufs nicht in unnötiger Weise aufgrund der Wärmekapazität der zunächst kalten Baugruppe zusätzlich Wärme entzogen, sondern die Wärme steht dem gewünschten Zweck, in der Praxis also beispielsweise der Innenraumerwärmung, zur Verfügung. Die Betriebskosten können somit aufgrund der verringerten elektrischen Zuheizung verringert und die Dauer bis zur Erwärmung vermindert werden. Die Erfindung geht dabei von der Erkenntnis aus, dass elektrische oder sonstige Baugruppen in der Kaltphase nicht etwa Wärme abgeben, sondern vielmehr dem Kühlmittel Wärme entziehen, was durch den Bypass vermieden werden kann. Selbstverständlich schließt das erfindungsgemäße Verfahren nicht die Nutzung der gegebenenfalls entstehenden Wärme der Baugruppen in anderen Betriebsphasen aus. Darüber hinaus wird auf diese Weise die Viskosität des Kühlmittels ebenso wie der Wirkungsgrad des Kühlmittelkreislaufs verbessert.According to the invention, therefore, a method is provided in which, in an operating phase below a predetermined coolant temperature, at least one heat-flowable by the coolant can flow shear of an assembly, which is associated with a high heat capacity, is separated by means of the bypass valve from the coolant flow. In a surprisingly simple manner required by the inventive method to achieve the required coolant temperature electrical heating is limited to a minimum that in the start or cold phase such assemblies that have not yet reached an operating point with a sufficient heat output, separated from the coolant circuit become. As a result, therefore, the coolant of the coolant circuit is not unnecessarily deprived of heat due to the heat capacity of the initially cold assembly, but the heat is the desired purpose, in practice, for example, the interior heating, available. The operating costs can thus be reduced due to the reduced electrical auxiliary heating and the duration is reduced until heating. The invention is based on the recognition that electrical or other assemblies in the cold phase not give off heat, but rather withdraw heat from the coolant, which can be avoided by the bypass. Of course, the method according to the invention does not exclude the use of the heat, if any, of the assemblies in other operating phases. In addition, in this way, the viscosity of the coolant as well as the efficiency of the coolant circuit is improved.
Die mittels des Bypassventils von dem Kühlmitteldurchfluss trennbaren Baugruppen könnten Wärmetauscher, mechanische Aggregate ebenso wie Leitungsabschnitte als solche sein. Hingegen ist es besonders vorteilhaft, wenn mittels des Bypassventils unterhalb einer vorbestimmten Kühlmitteltemperatur zumindest eine elektrische Baugruppe vom Kühlmittelfluss getrennt wird, um so in der Praxis problemlos eine vergleichsweise große Wärmekapazität von dem Kühlmittelkreislauf trennen zu können. Dabei können auch einzelne der mehreren elektrischen Baugruppen unabhängig voneinander von dem Kühlmittelfluss getrennt werden, um so die unterschiedliche Dauer der Erwärmung berücksichtigen und gegebenenfalls anfallende Abwärme einer elektrischen Baugruppe nutzen zu können. Bei Erreichen der Soll-Temperatur wird die jeweilige elektrische Baugruppe wieder in den Kühlmittelkreislauf eingebunden und von dem Kühlmittel durchströmt.The by means of the bypass valve from the coolant flow separable assemblies could be heat exchangers, mechanical Aggregates as well as line sections as such. On the other hand it is particularly advantageous if by means of the bypass valve below a predetermined coolant temperature at least one electrical assembly is separated from the coolant flow, so in practice easily a comparatively large Heat capacity of the coolant circuit to be able to disconnect. It can also be individual the multiple electrical assemblies independently be separated from the coolant flow, so the different Take into account the duration of heating and, if necessary use the waste heat of an electrical module to be able to. Upon reaching the target temperature, the respective electrical assembly back into the coolant circuit integrated and flows through the coolant.
Derartige Baugruppen finden sich in modernen Kraftfahrzeugen in verschiedensten Ausführungen. Besonders praxisrelevant ist hingegen eine Abwandlung, bei welcher mittels des Bypassventils eine Leistungselektronik, insbesondere umfassend einen Pulswechselrichter und einen DC/DC-Wandler und/oder eine Elektro-Maschine als Fahrmotor von dem Kühlmitteldurchfluss getrennt wird.such Assemblies can be found in modern motor vehicles in a variety of Versions. On the other hand, one is particularly relevant to practice Modification in which by means of the bypass valve power electronics, in particular comprising a pulse inverter and a DC / DC converter and / or an electric machine as a drive motor of the coolant flow is disconnected.
Ein in der Praxis relevanter Anwendungsfall des erfindungsgemäßen Verfahrens betrifft eine Ausgestaltung, bei welcher der Kühlmittelkreislauf zum Beheizen eines Fahrzeuginnenraums eines Kraftfahrzeugs genutzt wird. In ebenso Erfolg versprechender Weise dient das erfindungsgemäße Verfahren hingegen auch dem schnelleren Erreichen einer optimalen Betriebstemperatur der Brennkraftmaschine, um so beispielsweise unerwünschte Emissionen zu verringern.One in practice relevant application of the invention Method relates to an embodiment in which the coolant circuit used for heating a vehicle interior of a motor vehicle becomes. In just as promising way, the inventive serves Procedures, however, also the faster achievement of an optimal Operating temperature of the internal combustion engine, for example reduce unwanted emissions.
Die weitere erfindungsgemäße Aufgabe, eine mit einem Wärmetauscher ausgestattete Einrichtung zum Beheizen eines Fahrzeuginnenraums eines Kraftfahrzeugs, insbesondere Hybridfahrzeugs, mit einem eine Kühlmittelpumpe aufweisenden Kühlmittelkreislauf zur Durchführung des Verfahrens zu schaffen, dessen Kühlmittelkreislauf den Wärmetauscher, einen Kühler und eine Brennkraftmaschine verbindet, wobei mittels eines Bypassventils ein in dem Kreislauf angeordneter, mittels des Kühlmittels durchströmbarer Wärmetauscher einer elektrischen Baugruppe vom Kühlmittelfluss trennbar ist, wird erfindungsgemäß dadurch gelöst, dass mittels des Bypassventils zumindest ein einer Baugruppe hoher Wärmekapazität zugeordneter Wärmetauscher von dem Kühlmitteldurchfluss trennbar ist. Auf diese Weise wird also die zum Erreichen der gewünschten Kühlmitteltemperatur unerwünscht hohe Wärmekapazität der zunächst kalten Baugruppe von dem Kühlmittelkreislauf getrennt, sodass die Erwärmung des Kühlmittels beschleunigt erfolgt. Die Einrichtung ermöglicht so bei unveränderter Leistung eines elektrischen Zuheizers eine schnellere Innenraumerwärmung.The Another object of the invention, one with a Heat exchanger equipped device for heating a Vehicle interior of a motor vehicle, in particular a hybrid vehicle, with a coolant pump having a coolant pump to carry out the process to create the coolant circuit the heat exchanger, a radiator and an internal combustion engine connects, by means of a bypass valve in the circulation arranged, permeable by the coolant Heat exchanger of an electrical assembly from the coolant flow is separable, is achieved according to the invention, that by means of the bypass valve at least one of a module higher Heat capacity associated heat exchanger is separable from the coolant flow. In this way So is the to achieve the desired coolant temperature undesirably high heat capacity of the first cold assembly separated from the coolant circuit, so that the heating of the coolant accelerates he follows. The device allows so with unchanged Power of an electric heater a faster interior heating.
Bevorzugt ist hierzu mittels des Bypassventils zumindest eine elektrische Baugruppe vom Kühlmittelfluss trennbar, wobei auch der zugehörige Leitungsabschnitt so weitreichend wie möglich von dem Kühlmitteldurchfluss abgekoppelt werden kann.Prefers this is by means of the bypass valve at least one electrical Assembly of the coolant flow separable, wherein the associated line section as far-reaching as possible can be disconnected from the coolant flow.
Darüber hinaus hat es sich bereits als besonders vielversprechend erwiesen, wenn das Bypassventil und/oder die Kühlmittelpumpe sowie die elektrische Baugruppe als eine gemeinsame Baueinheit ausgeführt sind, um so die konstruktive Ausführung wesentlich zu vereinfachen. Dabei wird die Leistungselektronik, das Bypassventil sowie die Pumpe in die Baugruppe integriert.About that In addition, it has already proven to be particularly promising if the bypass valve and / or the coolant pump as well the electrical assembly designed as a common unit are so as to simplify the structural design significantly. The power electronics, the bypass valve and the pump in the assembly integrated.
Besonders praxisnah ist es auch, wenn die elektrische Baugruppe eine Leistungselektronik, insbesondere umfassend einen Pulswechselrichter und einen DC/DC-Wandler und/oder eine Elektro-Maschine als Fahrmotor aufweist, um vor allem große Wärmekapazitäten von dem Kühlmittelkreislauf trennen zu können.Especially It is also very practical if the electrical module has power electronics, in particular comprising a pulse inverter and a DC / DC converter and / or having an electric machine as a traction motor, in particular large heat capacities of the coolant circuit to be able to disconnect.
Der so wesentlich optimierte Kühlmittelkreislauf kann gewinnbringend bei nahezu jedem Kraftfahrzeug eingesetzt werden. Ein besonders praxisrelevanter Einsatzbereich wird auch dadurch geschaffen, dass der Kühlmittelkreislauf mit einem Wärmetauscher zum Beheizen eines Fahrzeuginnenraums eines Kraftfahrzeugs verbunden ist.The so much optimized coolant circuit Run can be used profitably in almost every motor vehicle. A particularly practical application is also created by the fact that the coolant circuit is connected to a heat exchanger for heating a vehicle interior of a motor vehicle.
