Abstract
Description
Die Erfindung betrifft ein Kraftfahrzeug mit einer motorunabhängigen, elek trisch betriebenen Heizvorrichtung für ein der Motorkühlung und/oder der Fahrzeug-Beheizung dienendes Wärmeträgermittel.The invention relates to a motor vehicle with a motor-independent, elec trisch operated heater for one of the engine cooling and / or Heat transfer medium used for vehicle heating.
Zum technischen Um feld wird beispielshalber auf die DE 195 23 905 A1 und die DE 44 33 814 A1 verwiesen.To the technical order As an example, Feld is referred to DE 195 23 905 A1 and DE 44 33 814 A1 referred.
Bekannt sind motorunabhängige Fahrzeug-Heizgeräte, in denen Kraftstoff, mit welchem auch der Kraftfahrzeug-Antriebsmotor versorgt wird, verbrannt wird. Ein derartiges Heizgerät ist beispielsweise in der erstgenannten Schrift gezeigt. In der zweitgenannten Schrift ist eine elektrische Heizvorrichtung bzw. Zusatzheizung für das der Motorkühlung und/oder Fahrzeug-Beheizung dienende Wärmeträgermittel gezeigt, welches aus einer Vielzahl von PTC- Elementen besteht. Erforderlich werden kann eine derartige elektrische Heizvorrichtung, die insbesondere aus Zusatzheizung ausgelegt sein kann, bei Einsatz der neueren wirkungsgradoptimierten Brennkraftmaschinen als Fahrzeug-Antriebsmotor, da diese Brennkraftmaschinen kaum mehr Ver lustwärme erzeugen und somit anschließend an einen Kaltstart eine relativ lange Zeitdauer benötigen, um ihre Betriebstemperatur zu erreichen. Als Folge hiervon fällt auch nur eine geringe Abwärme, die zur Fahrzeug- Beheizung genutzt werden kann, an. Eine zusätzliche elektrische Heizvor richtung, deren Energie von einem von der Brennkraftmaschine angetriebe nen Generator erzeugt wird, schafft hier wirkungsvoll Abhilfe. Zum einen wird die Brennkraftmaschine in ihrer Warmlaufphase höher belastet und er reicht somit bereits dadurch schneller ihre Betriebstemperatur, zum anderen wird das Wärmeträgermittel durch die elektrische Heizvorrichtung schneller erwärmt, so daß relativ kurzzeitig nach einem Kaltstart der Fahrzeug- Brennkraftmaschine letztere auch hierdurch schneller ihre Betriebstempera tur erreicht und zusätzlich bereits Wärme zur Beheizung des Fahrzeug- Innenraumes zur Verfügung steht.Engine-independent vehicle heaters are known in which fuel, with which the motor vehicle drive motor is supplied burned becomes. Such a heater is for example in the first-mentioned document shown. In the second document there is an electric heater or additional heating for the engine cooling and / or vehicle heating serving heat transfer medium shown, which consists of a variety of PTC Elements. Such an electrical may be required Heating device, which can be designed in particular from additional heating, when using the newer efficiency-optimized internal combustion engines than Vehicle drive motor, since these internal combustion engines hardly Ver generate lust heat and thus a relative after a cold start take a long time to reach their operating temperature. As As a result, only a small amount of waste heat falls, which Heating can be used. An additional electric heater direction, the energy of which is driven by the internal combustion engine Generating a generator is an effective remedy here. On the one hand the internal combustion engine is subjected to higher loads in its warm-up phase and he this means that their operating temperature is sufficient more quickly, on the other hand the heat transfer medium becomes faster through the electric heating device warmed up, so that the vehicle Internal combustion engine the latter also faster their operating temperature reached and in addition already heat for heating the vehicle Interior is available.
Während die eingangs genannten, mit Kraftstoff betriebenen Heizvorrich tungen äußerst aufwendig sind, besitzt eine elektrisch betriebene Heizvor richtung, die auf der Basis von PTC-Elementen arbeitet, einen relativ niedri gen Wirkungsgrad.During the fuel heating device mentioned at the beginning are extremely expensive, has an electrically operated Heizvor direction, which works on the basis of PTC elements, a relatively low efficiency.
Eine demgegenüber verbesserte Heizvorrichtung aufzuzeigen, ist daher Aufgabe der vorliegenden Erfindung.It is therefore necessary to show an improved heating device Object of the present invention.
Die Lösung dieser Aufgabe ist dadurch gekennzeichnet, daß die Heizvor richtung auf Mikrowellen-Basis arbeitet. Vorteilhafte Aus- und Weiterbildun gen sind Inhalt der Unteransprüche.The solution to this problem is characterized in that the Heizvor direction works on a microwave basis. Advantageous training and further education conditions are the content of the subclaims.
Es wird somit vorgeschlagen, das Wärmeträgermittel, welches wie üblich der Kühlung des Fahrzeug-Antriebsmotors und/oder der Beheizung des Fahrzeug-Innenraumes dienen kann, unter Zuhilfenahme des Mikrowellenprinzi pes zu erwärmen bzw. zu erhitzen. Normalerweise wird es sich bei diesem Wärmeträgermittel um die Kühlflüssigkeit der Fahrzeug-Brennkraftmaschine handeln, welche desweiteren über einen Fahrzeug-Heizungswärmetauscher, in welchem eine Wärmeübertragung auf einen in dem Fahrzeug-Innenraum zugeführten Luftstrom erfolgt, geführt wird oder geführt werden kann. Die vorliegende Erfindung ist jedoch auch auf elektromotorisch angetriebene Fahrzeuge anwendbar, die üblicherweise ebenfalls einen Wärmeträgerkreis lauf besitzen.It is therefore proposed that the heat transfer medium, which as usual Cooling the vehicle drive motor and / or the heating of the vehicle interior can serve with the help of the microwave prince pes to warm or heat. Usually this will be Heat transfer medium around the coolant of the vehicle internal combustion engine act, which furthermore via a vehicle heating heat exchanger, in which heat transfer to one in the vehicle interior supplied air flow takes place, is guided or can be guided. The However, the present invention is also driven by an electric motor Vehicles applicable, which usually also have a heat transfer circuit own run.
Ein besonderer Vorteil einer auf Mikrowellen-Basis arbeitenden Heizvorrich tung ist deren relativ hoher Wirkungsgrad, nachdem hier praktisch keinerlei Übertragungsverluste auftreten. Dem Wärmeträgermittel kann somit die elektrische Energie quasi direkt zugeführt werden, hohe Verluste in ohm schen Widerständen wie bei den PTC-Elementen treten nicht auf. Darüber hinaus ist der Aufbau einer auf Mikrowellen-Basis arbeitenden Heizvorrich tung relativ einfach, d. h. eine derartige Heizvorrichtung kann auf einfache Weise in das Kraftfahrzeug integriert werden, ohne hohe Sicherheitsanfor derungen erfüllen zu müssen.A particular advantage of a heating device working on a microwave basis tion is their relatively high efficiency, after practically none Transmission losses occur. The heat transfer medium can thus electrical energy can be supplied almost directly, high losses in ohms There are no resistances like the PTC elements. About that is also the construction of a heating device working on a microwave basis relatively easy, d. H. such a heater can be simple Ways can be integrated into the motor vehicle without high safety requirements changes.
Im übrigen sei kurz auf die DE 41 05 734 A1 als weiteren bekannten Stand der Technik hingewiesen, worin eine Mikrowellen-Beheizung zum schnellen Erwärmen eines Brennkraftmaschinen-Abgaskatalysators vorgeschlagen ist.For the rest, briefly refer to DE 41 05 734 A1 as another known state the technology pointed out, in which a microwave heating for fast Heating an internal combustion engine catalytic converter is proposed.
Da die elektrisch betriebene auf Mikrowellen-Basis arbeitende Heizvorrich tung selbstverständlich elektrische Energie benötigt, die in einem Kraftfahr zeug üblicherweise nicht unbeschränkt zur Verfügung gestellt werden kann, kann es empfehlenswert sein, diese Heizvorrichtung erst nach einem Start des Fahrzeug-Antriebsmotor in Gang zu setzen. Für den eigentlichen Start vorgang des Antriebsmotors/der Brennkraftmaschine steht dann in einer üb lichen Fahrzeug-Batterie ausreichend Energie zur Verfügung. Aufgrund des hohen Wirkungsgrades einer auf Mikrowellen-Basis arbeitenden Heizvor richtung ist jedoch auch keine Vorheizung erforderlich, vielmehr erfolgt auch bei einer Inbetriebnahme erst nach einem Start des Fahrzeug-An triebsmotors bereits relativ kurzfristig eine deutlich spürbare Erwärmung des Fahrzeug-Innenraumes.Since the electrically operated heating device working on a microwave basis of course, electrical energy is required in a motor vehicle usually cannot be made available without restriction, it may be advisable to start this heater only after a start of the vehicle drive motor. For the actual start The process of the drive motor / the internal combustion engine is then in a routine sufficient vehicle battery available. Because of the high efficiency of a microwave-based heating preheater direction, however, no preheating is required, rather it is done when commissioning, only after starting the vehicle drive motor a clearly noticeable warming in the short term of the vehicle interior.
Bevorzugt ist ein Heizbehälter mit einer Mikrowellen-Quelle vorgesehen, der entweder an den Wärmeträgerkreislauf für die Motorkühlung und/oder Fahr zeug-Beheizung angeschlossen ist oder in diesen Wärmeträgerkreislauf einbindbar ist. Dabei kann nach dem Prinzip eines Durchlauferhitzers gear beitet werden, d. h. der Heizbehälter wird im Falle einer Heizanforderung kontinuierlich mit Wärmeträgermittel durchströmt, wobei selbstverständlich die Mikrowellen-Quelle in Betrieb ist. Es ist aber auch möglich, den Heizbe hälter im Falle einer Heizanforderung diskontinuierlich mit Wärmemittel zu durchströmen. Dies bedeutet, daß stets eine gewisse Menge von Wärmeträ germittel im Heizbehälter ruht und in diesem bei betriebener Mikrowellen- Quelle erwärmt wird. Dieses erwärmte Wärmeträgermittel wird daran an schließend in den Wärmeträgerkreislauf eingeführt, gleichzeitig wird eine entsprechende Teilmenge kalten Wärmeträgermittels aus dem Wärmeträ gerkreislauf entnommen. Selbstverständlich ist hierfür ein geeignetes Schaltventil erforderlich, welches im übrigen ebenso wie die Mikrowellen- Quelle sowie eine gegebenenfalls erforderlichen Umwälzpumpe für das Wärmeträgermittel von einer elektronischen Steuereinheit angesteuert wer den kann. Daneben sind selbstverständlich eine Vielzahl weiterer Ergän zungen oder Abwandlungen möglich, ohne den Inhalt der Patentansprüche zu verlassen.A heating container with a microwave source is preferably provided, which either to the heat transfer circuit for engine cooling and / or driving Stove heating is connected or in this heat transfer circuit can be integrated. According to the principle of a water heater, gear be prepared, d. H. the heating tank will be in case of a heating request flows continuously with heat transfer medium, of course the microwave source is in operation. But it is also possible to use the heating in the event of a heating request discontinuously with heating medium flow through. This means that there is always a certain amount of heat transfer medium rests in the heating container and in this when the microwave Source is heated. This heated heat transfer medium is attached to it finally introduced into the heat transfer circuit, at the same time a corresponding subset of cold heat transfer medium from the heat transfer circuit removed. Of course, this is a suitable one Switching valve required, which, like the microwave Source and a possibly required circulation pump for the Heat transfer medium controlled by an electronic control unit that can. In addition, there are of course a variety of other additions tongues or modifications possible without the content of the claims to leave.
