Description
Die Erfindung betrifft ein Steuergerät für eine Pumpe in einem Kühlmittelkreislauf, mit dem in der Pumpe erzeugte Wärme abtransportierbar ist, wobei mit dem Steuergerät ein Motor der Pumpe einstellbar ist. Die Erfindung betrifft ebenso eine Anordnung aus einer Pumpe und dem Steuergerät, einen Kühlmittelkreislauf mit der Anordnung sowie ein Verfahren zum Temperieren einer Vorrichtung, die Teil des Kühlmittelkreislaufs ist.The invention relates to a control device for a pump in a coolant circuit, with which heat generated in the pump can be removed, a motor of the pump being adjustable with the control device. The invention also relates to an arrangement comprising a pump and the control device, a coolant circuit with the arrangement and a method for tempering a device which is part of the coolant circuit.
Kühlmittelkreisläufe dienen dazu, Vorrichtungen, insbesondere auch elektrische Vorrichtungen, in denen während des Betriebs Wärme entsteht, zu kühlen. Dazu werden die Vorrichtungen häufig über Wärmetauscher an Kühlmittelkreisläufe angeschlossen. Vorrichtungen, in denen im Betrieb Wärme entsteht, können zum Beispiel Batteriespeicher sein, wie sie auch in Elektrofahrzeugen eingesetzt werden.Coolant circuits are used to cool devices, in particular also electrical devices, in which heat is generated during operation. For this purpose, the devices are often connected to coolant circuits via heat exchangers. Devices in which heat is generated during operation can be, for example, battery storage devices, as are also used in electric vehicles.
Batteriespeicher, aber sicherlich auch andere Vorrichtungen, sollen, um die Lebensdauer zu erhöhen, aber auch nicht bei zu kalten Temperaturen betrieben werden, da sie sonst Schaden nehmen können. Die Gefahr, dass während des Betriebs Wärme produzierende Vorrichtungen bei zu kalten Temperaturen betrieben werden, besteht insbesondere dann, wenn sie eingeschaltet werden. Batteriespeicher sollten vorzugsweise darüber hinaus auch beim Aufladen eine bestimmte Temperatur nicht unterschreiten.Battery storage devices, but certainly also other devices, should be operated in order to increase the service life, but also not at too cold temperatures, since they can otherwise be damaged. There is a particular risk that devices that produce heat during operation are operated at too cold temperatures when they are switched on. Battery storage should also preferably not fall below a certain temperature when charging.
Hier setzt die Erfindung an.This is where the invention comes in.
Der Erfindung liegt die Aufgabe zu Grunde, die Funktion einer Pumpe dahingehend zu erweitern, dass sie auch als Wärmequelle zum Temperieren einer an einen Kühlmittelkreislauf angeschlossenen Vorrichtung genutzt werden kann.The invention is based on the object of expanding the function of a pump such that it can also be used as a heat source for tempering a device connected to a coolant circuit.
Die Aufgabe wird erfindungsgemäß dadurch gelöst, dass mittels des Steuergeräts der Wirkungsgrad der Pumpe, insbesondere des Motors der Pumpe einstellbar ist. Das Steuergerät kann so ausgeführt sein, dass der Wirkungsgrad der Pumpe, insbesondere des Motors so einstellbar ist, dass bei gleicher Nutzleistung die Verlustleistung, insbesondere die Wärmeleistung der Pumpe, insbesondere des Motors, erhöht oder vermindert wird. So kann bei gleicher Nutzleistung mit dem erfindungsgemäßen Steuergerät die Wärme erhöht und/oder vermindert werden, die von dem Kühlmittelkreislauf dann zu der zu erwärmenden Vorrichtung transportiert wird.The object is achieved in that the efficiency of the pump, in particular the motor of the pump, can be set by means of the control device. The control unit can be designed in such a way that the efficiency of the pump, in particular the motor, can be adjusted such that the power loss, in particular the thermal output of the pump, in particular the motor, is increased or decreased with the same useful power. Thus, with the same useful power, the control device according to the invention can be used to increase and / or reduce the heat which is then transported from the coolant circuit to the device to be heated.
Eine erfindungsgemäße Anordnung umfasst eine Pumpe und ein erfindungsgemäßes Steuergerät zum Steuern der Pumpe. Der Motor der Pumpe kann durch einen von der Pumpe pumpbaren Kühlmittelstrom gekühlt werden.An arrangement according to the invention comprises a pump and a control device according to the invention for controlling the pump. The motor of the pump can be cooled by a coolant flow that can be pumped by the pump.
Eine erfindungsgemäße Anordnung kann zusammen mit einer zu temperierenden Vorrichtung Teil eines erfindungsgemäßen Kühlmittelkreislaufs sein, worin die zu temperierende Vorrichtung zumindest zeitweise durch eine Wärmeleistung der Pumpe erwärmt werden kann.An arrangement according to the invention, together with a device to be temperature-controlled, can be part of a coolant circuit according to the invention, in which the device to be temperature-controlled can be heated, at least temporarily, by a thermal output of the pump.
Eine Vorrichtung, die Teil eines erfindungsgemäßen Kühlmittelkreislaufs ist, kann erfindungsgemäß so gesteuert werden, dass mit einem Temperatursensor eine Temperatur der zu temperierenden Vorrichtung erfasst wird und die erfasste Temperatur mit einer vorgegebenen Temperatur verglichen wird. In dem Fall, dass die erfasste Temperatur niedriger ist als die vorgegebene Temperatur, wird mittels der Steuerung der Pumpe die Pumpe so eingestellt, dass die Verlustleistung, insbesondere die Wärmeleistung der Pumpe erhöht ist. Durch die Pumpe wird zusätzlich Wärme erzeugt, die der zu temperierenden Vorrichtung zugeführt wird.A device that is part of a coolant circuit according to the invention can be controlled according to the invention in such a way that a temperature of the device to be temperature-controlled is detected with a temperature sensor and the detected temperature is compared with a predetermined temperature. In the event that the detected temperature is lower than the predetermined temperature, the pump is set by means of the control of the pump so that the power loss, in particular the heat output of the pump, is increased. The pump also generates heat, which is supplied to the device to be tempered.
In dem Fall, dass die erfasste Temperatur höher ist als die vorgegebene Temperatur kann mittels der Steuerung der Pumpe die Pumpe so eingestellt werden, dass die Verlustleistung, insbesondere die Wärmeleistung der Pumpe für die eingestellte Nutzleistung der Pumpe minimiert ist.In the event that the detected temperature is higher than the predetermined temperature, the pump can be set by means of the control of the pump such that the power loss, in particular the heat output of the pump is minimized for the set useful output of the pump.
