Abstract
Description
Die Erfindung betrifft ein Wärmemanagementsystem mit den Merkmalen des Oberbegriffs des Patentanspruchs 1.The invention relates to a thermal management system having the features of the preamble of patent claim 1.
In der Automobiltechnik werden verstärkt Wärmemanagementsysteme verwendet, die einerseits Kühlaufgaben erledigen, die sich durch alternative Antriebsformen oft vielfältig gestalten. So sind beispielsweise elektrische Aggregate zu kühlen, die einen anderen Kühltemperaturbereich aufweisen, als eine Verbrennungskraftmaschine. Dabei können sich Komforteinbußen ergeben, die aus einer zu geringen Heizleistung herrühren. So ist in der
Der Erfindung liegt die Aufgabe zu Grunde, ein derartiges Wärmemanagementsystem zu schaffen, das eine möglichst komfortable Heizfunktion mit möglichst geringem Energieaufwand und Kraftstoffverbrauch ermöglicht.The invention is based on the object to provide such a thermal management system that allows the most comfortable heating function with the lowest possible energy consumption and fuel consumption.
Die Aufgabe wird durch ein Wärmemanagementsystem mit den Merkmalen des Patentanspruchs 1 gelöst. Ein derartiges Wärmemanagementsystem eines Kraftfahrzeugs weist einen Niedertemperaturkreislauf und einen Hochtemperaturkreislauf auf, wobei ein der Fahrzeugkabine zugeführter Luftstrom mittels beider Kreisläufe direkt über mindestens einen durchströmten Wärmetauscher heizbar ist. Dadurch wird bewirkt, dass je nach Betriebsfall sowohl Wärme eines Niedertemperaturkreislaufs, als auch Wärme eines Hochtemperaturkreislaufs effektiv genutzt werden kann, so dass ein Energieaufwand für Zuheizmaßnahmen möglichst gering gehalten werden kann. Dabei kann der Hochtemperaturkreislauf beispielsweise an eine Verbrennungskraftmaschine angeschlossen sein und nur zeitweise Abwärme liefern. Zur direkten Beheizung des Luftstromes mittels des Nieder- und des Hochtemperaturkreislaufs kann ein Wärmetauscher vorgesehen sein, der beispielsweise durch Umschaltung wahlweise mit einem Kühlmittelstrom des Nieder- oder des Hochtemperaturkreislaufs beaufschlagbar ist.The object is achieved by a thermal management system having the features of patent claim 1. Such a thermal management system of a motor vehicle has a low-temperature circuit and a high-temperature circuit, wherein an air stream supplied to the vehicle cabin can be heated by means of both circuits directly via at least one through-flowed heat exchanger. This has the effect that, depending on the operating conditions, both heat of a low-temperature circuit and heat of a high-temperature circuit can be used effectively, so that an energy expenditure for additional heating measures can be kept as low as possible. In this case, the high-temperature circuit may be connected, for example, to an internal combustion engine and only temporarily provide waste heat. For direct heating of the air flow by means of the low and the high-temperature circuit, a heat exchanger may be provided which can be acted upon, for example by switching with either a coolant flow of the low or the high-temperature circuit.
Bei einer vorteilhaften Ausführungsform des Wärmemanagementsystems sind zwei separate Wärmetauscher vorgesehen, von denen einer im Niedertemperaturkreislauf und einer im Hochtemperaturkreislauf angeordnet ist. Einerseits können die beiden Wärmetauscher baulich besonders frei auf die jeweils zu Grunde liegenden technischen Anforderungen im Niedertemperaturkreislauf und im Hochtemperaturkreislauf abgestimmt werden, andererseits können diese auch aus Gründen der Bauraumoptimierung voneinander separiert angeordnet werden.In an advantageous embodiment of the thermal management system, two separate heat exchangers are provided, one of which is arranged in the low-temperature circuit and one in the high-temperature circuit. On the one hand, the two heat exchangers structurally particularly free to the respective underlying technical requirements in the low-temperature circuit and in the high-temperature circuit can be tuned, on the other hand, they can also be separated from each other for reasons of space optimization.
Um den Vorteil einer kompakten und integralen Bauform des Wärmetauschers zu erreichen, ist bei einer Ausgestaltung des Wärmemanagementsystems ein zweiflutiger Wärmetauscher vorgesehen, dessen beide Fluten jeweils einem der beiden Kühlmittelkreisläufe zugeordnet sind. Die beiden Fluten können beispielsweise durch Gestaltung der jeweiligen Durchströmung, der Tauschergitter oder der Tiefe trotzdem gut spezifisch auf den jeweiligen Kreislauf abgestimmt werden.In order to achieve the advantage of a compact and integral design of the heat exchanger, a two-flow heat exchanger is provided in one embodiment of the thermal management system, the two floods are each associated with one of the two coolant circuits. Nevertheless, the two floods can be adapted to the respective circuit, for example, by designing the respective throughflow, the exchanger grid or the depth.
Bei einer besonders vorteilhaften Ausführungsform ist im Hochtemperaturkreislauf ein Zuheizer angeordnet. Dieser Zuheizer kann beispielsweise bei einem Hybridantrieb zusätzlich zu einem anderen, eventuell nur temporär heizenden Aggregat im Hochtemperaturkreislauf angeordnet sein und bei entsprechender Heizleistungsanforderung und fehlender Erwärmung durch dieses Aggregat das Kühlmittel erwärmen. Es kann aber auch, beispielsweise bei einem reinen Elektroantrieb ein Hochtemperaturkreislauf vorgesehen sein, der im Wesentlichen den Zuheizer, eine Umwälzpumpe, die gegebenenfalls im Zuheizer integriert ist, und den Wärmetauscher aufweist. Dieser Hochtemperaturkreislauf wird dann bei einer entsprechend hohen Heizleistungsanforderung in Betrieb genommen, die vom Niedertemperaturkreislauf nicht abgedeckt werden kann.In a particularly advantageous embodiment, a heater is arranged in the high-temperature circuit. In the case of a hybrid drive, for example, this auxiliary heater can be arranged in the high-temperature circuit in addition to another, possibly only temporary, heating unit and, given a corresponding heating power requirement and lack of heating by this unit, heat the coolant. However, it may also be provided, for example in a pure electric drive, a high-temperature circuit, which essentially has the auxiliary heater, a circulating pump, which is optionally integrated in the auxiliary heater, and the heat exchanger. This high-temperature circuit is then put into operation at a correspondingly high heating power requirement, which can not be covered by the low-temperature circuit.
Eine vorteilhafte Ausgestaltung des Wärmemanagementsystems weist einen Niedertemperaturkreislauf auf, in dem ein Elektro-Antriebsmotor des Fahrzeugs durchströmt angeordnet ist. Dadurch ist es möglich, die im Elektro-Antriebsmotor entstehende Wärme mittels eines entsprechend abgestimmten Wärmetauschers zum Beheizen der Fahrzeugkabine zu nutzen.An advantageous embodiment of the thermal management system has a low-temperature circuit in which an electric drive motor of the vehicle flows through. This makes it possible to use the heat generated in the electric drive motor by means of a suitably tuned heat exchanger for heating the vehicle cab.
Um eine gesicherte Wärmeabfuhr an den zum Niedertemperaturkreislauf gehörenden Aggregaten zu gewährleisten, ist bei einer vorteilhaften Ausgestaltung des Wärmemanagementsystems der Kühlmittelstrom des Niedertemperaturkreislaufs zwischen einer Durchflutung des zugehörigen Wärmetauschers und eines Wärme an die Umgebung abführenden Kühlers umschaltbar.In order to ensure reliable heat dissipation to the units belonging to the low-temperature circuit, in an advantageous embodiment of the thermal management system of the coolant flow of the low-temperature circuit between a flooding of the associated heat exchanger and a heat to the environment dissipating radiator switchable.
