Description
Die vorliegende Erfindung betrifft ein Verfahren zum Erstbefüllen der Kühlkreisläufe eines Fahrzeugs mit zumindest zwei Kühlkreisläufen sowie ein solches Fahrzeug mit zumindest zwei Kühlkreisläufen.The present invention relates to a method for first filling the cooling circuits of a vehicle with at least two cooling circuits and such a vehicle with at least two cooling circuits.
Die Verwendung von Kühlkreisläufen zum Kühlen von Komponenten eines Kraftfahrzeuges ist hinlänglich bekannt. Ein im Kreislauf zirkulierendes Kühlmittel, zum Beispiel Wasser, wird an der zu kühlenden Komponente entlanggeführt, erwärmt sich dabei und gibt die aufgenommene Wärme an einer Wärmesenke, beispielsweise mittels eines Wärmetauschers, wieder ab. Bei der Herstellung des Kühlkreislaufes muss das erforderliche Kühlmittel, im Rahmen einer Erstbefüllung, in den Kühlkreislauf einmalig eingebracht werden.The use of cooling circuits for cooling components of a motor vehicle is well known. A coolant circulating in the circulation, for example water, is guided along the component to be cooled, heats up and releases the absorbed heat at a heat sink, for example by means of a heat exchanger. During the production of the cooling circuit, the required coolant, as part of a first filling, must be introduced once in the cooling circuit.
Manche Fahrzeuge verwenden auch zwei oder mehrere getrennte Kühlkreisläufe, beispielsweise Hybridfahrzeuge zum Kühlen von Komponenten der Verbrennungskraftmaschine einerseits und von Komponenten des elektrischen Antriebes andererseits. Beispielsweise kann in den Kühlkreisläufen das selbe Kühlmittel bei unterschiedlichen Temperaturen verwendet werden. Bei der Herstellung von Fahrzeugen mit mehreren Kühlkreisläufen wird üblicherweise für jeden Kühlkreislauf eine eigene Befüllungsanlage in der Montagelinie des Fahrzeugs eingesetzt.Some vehicles also use two or more separate cooling circuits, for example hybrid vehicles for cooling components of the internal combustion engine on the one hand and components of the electric drive on the other hand. For example, the same coolant can be used at different temperatures in the cooling circuits. In the production of vehicles with multiple cooling circuits usually for each cooling circuit a separate filling plant is used in the assembly line of the vehicle.
Aus der
Diese Einrichtung für eine Erstbefüllung ist jedoch aufwändig und teuer in der Herstellung und funktioniert auch nur bei unterschiedlichen Temperaturen des Kühlmittels.However, this device for a first filling is complicated and expensive to manufacture and also works only at different temperatures of the coolant.
Es ist eine Aufgabe der Erfindung, ein Verfahren zum Erstbefüllen der Kühlkreisläufe eines Fahrzeugs mit zumindest zwei Kühlkreisläufen anzugeben, dass einfach und kostengünstig durchzuführen ist und ein Fahrzeug mit zumindest zwei Kühlkreisläufen anzugeben, dass für ein solches Verfahren vorbereitet ist.It is an object of the invention to specify a method for initially filling the cooling circuits of a vehicle with at least two cooling circuits that is simple and inexpensive to perform and to provide a vehicle with at least two cooling circuits that is prepared for such a method.
Die Lösung der Aufgabe erfolgt durch ein Verfahren zum Erstbefüllen der Kühlkreisläufe eines Fahrzeugs mit zumindest zwei Kühlkreisläufen, wobei die mindestens zwei Kühlkreisläufe während der Befüllung über zumindest eine zwischen den zwei Kühlkreisläufen eingerichtete fluidleitende Verbindung, umfassend eine Verbindungsleitung, verbunden sind und mittels dieser fluidleitenden Verbindung gleichzeitig befüllt werden, wobei die fluidleitende Verbindung nach dem Befüllen dauerhaft geschlossen wird.The object is achieved by a method for first filling the cooling circuits of a vehicle with at least two cooling circuits, wherein the at least two cooling circuits during filling via at least one established between the two cooling circuits fluid-conducting connection, comprising a connecting line, are connected and simultaneously by means of this fluid-conducting connection be filled, where the fluid-conducting connection is closed permanently after filling.
Die Erstbefüllung der Kühlkreisläufe, die üblicherweise während der Herstellung des Fahrzeugs durchgeführt wird, erfolgt somit erfindungsgemäß gleichzeitig, da die Kühlkreisläufe während der Erstbefüllung über eine fluidleitende Verbindungsleitung verbunden sind, so dass das Kühlmedium von einem Kühlkreislauf in einen anderen - während eines Normalbetriebes des Fahrzeuges getrennten- Kühlkreislauf strömen kann. Die fluidleitende Verbindung wird nach der Erstbefüllung geschlossen, so dass es nach der Erstbefüllung keine Strömungsverbindung zwischen den Kühlkreisläufen über die Verbindungsleitung mehr gibt. Da das selbe Kühlmittel bei der Erstbefüllung erfindungsgemäß in den jeweils anderen Kühlkreislauf überströmt verwenden die beiden Kühlkreisläufe auch im Normalbetrieb das gleiche Kühlmittel.The first filling of the cooling circuits, which is usually carried out during the manufacture of the vehicle, thus takes place simultaneously according to the invention, since the cooling circuits are connected during the Erstbefüllung via a fluid-conducting connection line, so that the cooling medium from one cooling circuit to another - during normal operation of the vehicle separated - Can flow cooling circuit. The fluid-conducting connection is closed after the first filling, so that there is no flow connection between the cooling circuits via the connecting line after the first filling. Since the same coolant flows according to the invention into the respective other cooling circuit during the first filling, the two cooling circuits also use the same coolant during normal operation.
Weiterbildungen der Erfindung sind in den abhängigen Ansprüchen, der Beschreibung sowie den beigefügten Zeichnungen angegeben.Further developments of the invention are specified in the dependent claims, the description and the accompanying drawings.
Bevorzugt wird die fluidleitende Verbindung nach dem Befüllen durch Schließen von einem oder zwei Absperrventilen dauerhaft geschlossen. Besonders bevorzugt werden zwei Absperrventile verwendet, wobei jeweils ein Absperrventil einem Ende der Verbindungsleitung zugeordnet ist. Die Absperrventile können bevorzugt mit einem Spezialwerkzeug irreversibel geschlossen werden.Preferably, the fluid-conducting connection is closed permanently after filling by closing one or two shut-off valves. Two shut-off valves are particularly preferably used, one shut-off valve being assigned to one end of the connecting line. The shut-off valves can preferably be closed irreversibly with a special tool.
Die Verbindungsleitung kann nach dem Befüllen im Fahrzeug verbleiben oder auch aus dem Fahrzeug entfernt werden. Insbesondere längere Verbindungsleitungen, beispielsweise länger als 15 cm, werden vorzugsweise entfernt um Gewicht und Kosten einzusparen.The connecting line can remain in the vehicle after filling or can also be removed from the vehicle. In particular, longer connecting lines, for example longer than 15 cm, are preferably removed in order to save weight and costs.
Beispielsweise können jeweils Rücklaufleitungen der zwei Kühlkreisläufe über die Verbindungsleitung miteinander verbunden sein, oder auch jeweils Wärmetauscher der zwei Kühlkreisläufe über die Verbindungsleitung miteinander verbunden sein.For example, return lines of the two cooling circuits can be connected to one another via the connecting line, or heat exchangers of the two cooling circuits can also be connected to one another via the connecting line.
In einem erfindungsgemäß vorbereiteten Fahrzeug mit zumindest zwei Kühlkreisläufen, ist zwischen den zwei Kühlkreisläufen zumindest eine fluidleitende Verbindung eingerichtet, wobei die fluidleitende Verbindung eine Verbindungsleitung umfasst und ein Mittel zum dauerhaften Schließen der fluidleitenden Verbindung zwischen den zwei Kühlkreisläufen.In a vehicle prepared according to the invention having at least two cooling circuits, at least one fluid-conducting connection is set up between the two cooling circuits, the fluid-conducting connection comprising a connecting line and a means for permanently closing the fluid-conducting connection between the two cooling circuits.

Das Mittel zum dauerhaften Schließen kann zumindest ein Absperrventil umfassen, wobei das Absperrventil in der Verbindungsleitung oder in einem Anschlussbereich der Verbindungsleitung am Kühlkreislauf angeordnet ist. Insbesondere wenn die Verbindungsleitung nach der Erstbefüllung entfernt wird, wird das Absperrventil am Fahrzeug selbst ausgebildet sein.The means for permanently closing may comprise at least one shut-off valve, wherein the shut-off valve is arranged in the connecting line or in a connection region of the connecting line to the cooling circuit. In particular, if the connecting line is removed after the first filling, the shut-off valve will be formed on the vehicle itself.
Die Verbindungsleitung kann bevorzugt einander naheliegende Bereiche der beiden Kühlkreisläufe miteinander verbinden, insbesondere zwei einander naheliegende Wärmetauscher oder einen Wärmetauscher mit einer naheliegenden Kühlkreisleitung des anderen Kühlkreislaufes, so dass die Verbindungsleitung kurz, insbesondere kürzer als 50 cm, bevorzugt kürzer als 15 cm ausgebildet werden kann.The connecting line may preferably connect mutually adjacent regions of the two cooling circuits with one another, in particular two heat exchangers lying close to each other or a heat exchanger with a cooling circuit of the other cooling circuit lying close to it, so that the connecting line can be short, in particular shorter than 50 cm, preferably shorter than 15 cm.
Die Kühlkreisläufe können durch die Verbindungsleitung oder mehrere Verbindungsleitungen seriell oder parallel miteinander fluidleitend verbunden sein, so dass bei der Erstbefüllung mehrerer Kühlkreisläufe entweder das Kühlmittel von einem Kühlkreislauf jeweils zum nächsten benachbarten Kühlkreislauf überströmt oder aber zu mehreren oder allen Kühlkreisläufen gleichzeitig überströmt.The cooling circuits can be fluidly connected to one another in series or in parallel by the connecting line or a plurality of connecting lines, so that either the coolant flows over from one cooling circuit to the next adjacent cooling circuit or overflows to several or all of the cooling circuits at the first filling of several cooling circuits.
Erfindungsgemäß kann die Verbindungsleitung zumindest an einem ihrer Enden, bevorzugt an beiden Enden, ein erstes Kupplungsteil aufweisen zum Einstecken der Verbindungsleitung in ein entsprechendes zweites Kupplungsteil an einem der Kühlkreisläufe. Zwischen Verbindungsleitung und Kühlkreislauf ist also eine Steckverbindung eingerichtet.According to the invention, the connecting line can have at least at one of its ends, preferably at both ends, a first coupling part for inserting the connecting line into a corresponding second coupling part on one of the cooling circuits.

Besonders bevorzugt ist das zweite Kupplungsteil so ausgebildet, dass beim Entfernen des ersten Kupplungsteils vom zweiten Kupplungsteil im zweiten Kupplungsteil ein Dichtelement durch ein erstes elastisches Element, beispielsweise eine Feder, gegen einen Dichtsitz gedrückt wird.Particularly preferably, the second coupling part is formed so that when removing the first coupling part from the second coupling part in the second coupling part, a sealing element is pressed by a first elastic element, such as a spring, against a sealing seat.
Das erste Kupplungsteil kann eine Nadel aufweisen, die beim Annähern an das zweite Kupplungsteil ein Dichtelement des zweiten Kupplungsteils von seinem Dichtsitz wegdrückt. Die Form der Nadel ist dabei nicht eingeschränkt, solange die Nadel das Dichtelement erreichen und aus seiner Dichtposition wegdrücken kann.The first coupling part may comprise a needle which, when approaching the second coupling part, pushes a sealing element of the second coupling part away from its sealing seat. The shape of the needle is not limited, as long as the needle can reach the sealing element and push away from its sealing position.
