Description
Die Erfindung betrifft ein Verfahren zur Kontrolle der vollständigen Entlüftung eines eine Kühlflüssigkeit enthaltenden Kühlkreislaufs, dem eine Kühlmittelpumpe und ein Drucksensor zugeordnet ist, umfassend die Schritte der Durchführung einer Entlüftungsroutine und nachfolgend Erzeugen eines Druckhubes mit einem vorgegebenen Druck mittels der Kühlmittelpumpe, Erfassen des Druckes in der Kühlflüssigkeit mittels des Drucksensors, Vergleich des erzeugten Druckes mit dem erfassten bzw. gemessenen Druck und Schließen auf eine unzureichende Entlüftung, wenn die Druckdifferenz zwischen dem erzeugten Druck und dem erfassten bzw. gemessene Druck größer als ein Schwellenwert ist. Die Erfindung betrifft weiterhin einen Kühlkreislauf, eine Brennstoffzellenvorrichtung und ein Kraftfahrzeug mit einem Kühlkreislauf.The invention relates to a method for controlling the complete venting of a cooling circuit containing a cooling liquid, to which a coolant pump and a pressure sensor are assigned, comprising the steps of performing a venting routine and then generating a pressure stroke with a predetermined pressure by means of the coolant pump, detecting the pressure in the Cooling liquid by means of the pressure sensor, comparison of the pressure generated with the detected or measured pressure and conclusions on insufficient venting if the pressure difference between the generated pressure and the detected or measured pressure is greater than a threshold value. The invention further relates to a cooling circuit, a fuel cell device and a motor vehicle with a cooling circuit.
Kühlkreisläufe sind vor ihrer Inbetriebnahme zu entlüften, um später gewährleisten zu können, dass aufgrund von im Kühlkreislauf vorhandener Luft keine Überhitzungen entstehen. Für die Entlüftung sind entsprechende Entlüftungsroutinen bekannt. Die Dauer der Entlüftungsroutine stammt von einem aus Versuchen abgeleiteten Modell des Kühlkreislaufes, wobei durchsichtige Rohre Verwendung finden können. Anhand dieser Rohre kann bei dem Versuchsaufbau kontrolliert und erfasst werden, wann die Entlüftung des Kühlkreislaufs vollständig abgeschlossen ist. Die aus diesen Versuchen modellierte Entlüftungsroutine wird auf alle Module übertragen, die in den Kühlkreislauf eingebunden sind. Da es der in einem Kraftfahrzeug eingesetzten Kühlmittelleitung an der entsprechenden Transparenz zur Sichtung von Luft im Kühlkreislauf fehlt, besteht keine Möglichkeit, zu überprüfen, ob die Entlüftungsroutine vor der Inbetriebnahme ausgereicht hat, um die Luft aus dem Kühlkreislauf abzuscheiden. Damit besteht die Gefahr einer Beschädigung von zu kühlenden Bauteilen, da bei Luft im Kühlmittelkreislauf die Wärme von den zu kühlenden Stellen nicht abgeführt werden und es zu Überhitzungen und Beschädigungen des Bauteils kommen kann. Um diesem Problem zu begegnen, wird die Entlüftungsroutine entsprechend verlängert, was zeit- und kostenintensiv ist. Auch im Wartungsfalle des Kraftfahrzeugs kann eine entsprechende Entlüftungsroutine notwendig werden, sodass auch in den Werkstätten zusätzliche Kosten aufgrund der Verzögerungen im Ablauf entstehen können. Gerade der Kühlkreislauf eines Brennstoffzellenfahrzeugs fasst im Vergleich zum Fahrzeug mit einem klassischen Verbrennungsmotor ein deutlich größeres Volumen an Kühlmittel, sodass auch hier entsprechend verlängerte Entlüftungsroutinen erforderlich sind, um zu gewährleisten, dass die Luft aus dem Kühlkreislauf in die Kühlmittelausgleichsanordnung abgeschieden wird. Auch hier wird deshalb eine Entlüftungsroutine vor der Inbetriebnahme der Brennstoffzellenaggregate durchgeführt, die zeit- und kostenaufwendig ist.Cooling circuits must be vented before they are put into operation in order to be able to guarantee later that no overheating occurs due to the air in the cooling circuit. Corresponding venting routines are known for venting. The duration of the venting routine comes from a model of the cooling circuit derived from experiments, whereby transparent tubes can be used. With the help of these pipes, it can be checked and recorded during the test setup when the ventilation of the cooling circuit is completely completed. The venting routine modeled from these tests is transferred to all modules that are integrated into the cooling circuit. Since the coolant line used in a motor vehicle lacks the appropriate transparency for sifting air in the cooling circuit, there is no way of checking whether the venting routine was sufficient before commissioning to separate the air from the cooling circuit. This means that there is a risk of damage to components to be cooled, since if there is air in the coolant circuit, the heat is not dissipated from the points to be cooled and the component can overheat and be damaged. To counter this problem, the venting routine is extended accordingly, which is time-consuming and costly. A corresponding venting routine may also be necessary when the motor vehicle is being serviced, so that additional costs may arise in the workshops due to the delays in the process. In particular, the cooling circuit of a fuel cell vehicle holds a significantly larger volume of coolant compared to a vehicle with a classic internal combustion engine, so that here, too, correspondingly extended venting routines are required to ensure that the air from the cooling circuit is separated into the coolant equalization arrangement. Here too, a venting routine is therefore carried out before the fuel cell units are put into operation, which is time-consuming and costly.
Die
Aufgabe der vorliegenden Erfindung ist es, ein Verfahren bereit zu stellen, mit dem der Erfolg einer Entlüftungsroutine bewertet werden kann. Aufgabe ist weiterhin, einen verbesserten Kühlkreislauf, eine verbesserte Brennstoffzellenvorrichtung und ein verbessertes Kraftfahrzeug bereit zu stellen.The object of the present invention is to provide a method with which the success of a venting routine can be assessed. A further object is to provide an improved cooling circuit, an improved fuel cell device and an improved motor vehicle.
Diese Aufgabe wird durch ein Verfahren mit den Merkmalen des Anspruchs 1, durch einen Kühlkreislauf mit den Merkmalen des Anspruchs 5, durch eine Brennstoffzellenvorrichtung mit den Merkmalen des Anspruchs 7 und durch ein Kraftfahrzeug mit den Merkmalen des Anspruchs 8 sowie des Anspruchs 9 gelöst. Vorteilhafte Ausgestaltungen mit zweckmäßigen Weiterbildungen der Erfindung sind in den abhängigen Ansprüchen angegeben.This object is achieved by a method with the features of claim 1, by a cooling circuit with the features of claim 5, by a fuel cell device with the features of claim 7 and by a motor vehicle with the features of claim 8 and claim 9. Advantageous configurations with expedient developments of the invention are specified in the dependent claims.
Das erfindungsgemäße Verfahren zur Kontrolle der vollständigen Entlüftung eines eine Kühlflüssigkeit enthaltenden Kühlkreislaufs nutzt aus, dass mit der Kühlmittelpumpe ein Druckhub, also ein impulsartiger Druckstoß ausgeführt werden kann, der durch die inkompressible Kühlflüssigkeit im wesentlich unverändert durchläuft und mit dem Drucksensor stromab der Kühlmittelpumpe erfasst werden kann. Liegt nun eine unzureichende Entlüftung vor, so wird die Luftblase komprimiert und durch die dafür erforderliche Kompressionsarbeit der Druck abgebaut. Ergibt der Vergleich des erzeugten Druckes mit dem erfassten bzw. gemessenen Druck eine zu große Abweichung, liegt eine unzureichende Entlüftung vor.The method according to the invention for checking the complete venting of a cooling circuit containing a cooling liquid takes advantage of the fact that a pressure stroke, i.e. a pulse-like pressure surge, can be carried out with the coolant pump, which passes through the incompressible cooling liquid essentially unchanged and can be detected with the pressure sensor downstream of the coolant pump . If there is insufficient ventilation, the air bubble is compressed and the pressure is reduced by the compression work required for this. If the comparison of the pressure generated with the recorded or measured pressure shows too great a deviation, then there is insufficient ventilation.
Dabei wird die Größe des Druckhubes abhängig von der Drehzahl der Kühlmittelpumpe bestimmt, so dass ein Kennfeld des erzeugten Druckes bei einem gegebenen Druckhub in Abhängigkeit von der Drehzahl der Kühlmittelpumpe erstellt wird und der zu einer vorgegebenen Drehzahl gemessene Druck mit dem Wert aus dem Kennfeld verglichen wird.The size of the pressure stroke is determined depending on the speed of the coolant pump, so that a map of the pressure generated at a given pressure stroke is created as a function of the speed of the coolant pump and the pressure measured at a given speed is compared with the value from the map.
Bei Feststellen einer unzureichenden Entlüftung wird die Entlüftungsroutine wiederholt.If insufficient venting is found, the venting routine is repeated.
Zur Durchführung des Verfahrens verfügt der Kühlkreislauf mit einer Kühlmittelpumpe zur Förderung einer Kühlflüssigkeit und eines Drucksensors zur Erfassung des vorliegenden Druckes über ein Steuergerät, das insbesondere eine Speichereinheit für das Kennfeld sowie einen Komparator für den Vergleich der Daten aus dem Kennfeld mit den Daten des Drucksensors aufweist.To carry out the method, the cooling circuit with a coolant pump for conveying a cooling liquid and a pressure sensor for detecting the existing pressure has a control unit which in particular has a memory unit for the map and a comparator for comparing the data from the map with the data from the pressure sensor .
Die vorstehend genannten Vorteile und Wirkungen gelten sinngemäß auch für eine Brennstoffzellenvorrichtung mit einem derartigen Kühlkreislauf oder für ein Kraftfahrzeug mit einem derartigen Kühlkreislauf und/oder einer Brennstoffzellenvorrichtung mit einem entsprechenden Kühlkreislauf.The above-mentioned advantages and effects also apply mutatis mutandis to a fuel cell device with such a cooling circuit or for a motor vehicle with such a cooling circuit and / or a fuel cell device with a corresponding cooling circuit.
