Description

Die Erfindung betrifft ein Wärmeaustauschsystem für die Heizung eines Straßenfahrzeuges mit Elektroantrieb, wobei zur Steuerung des Fahrmotors Leistungshalbleiter eingesetzt werden, die beim Fahrbetrieb Wärme abgeben.The invention relates to a heat exchange system for the Heating a road vehicle with an electric drive, wherein Power semiconductors are used to control the drive motor that give off heat when driving.

Es ist bekannt, bei elektrisch angetriebenen Fahrzeugen zum Zweck der Heizung von Innenräumen den elektrischen Strom direkt in Wärme umzuwandeln.It is known in electrically powered vehicles for the purpose of heating indoor electrical Convert electricity directly into heat.

Dabei ergibt sich zwar ein sehr guter Wirkungsgrad, jedoch muß die zur Heizung benötigte Energie auch in ausreichender Menge zur Verfügung stehen. Diese Voraussetzung ist aber nur gegeben, wenn der elektrische Strom dem Fahrzeug ständig über Fahrdrähte oder Stromschienen zugeführt wird. Derartige Fahrzeuge sind aber nicht überall betreibbar, sondern nur auf besonders dafür eingerichteten Straßen (O-Bus) oder Schienenstrecken (Bahn).This results in very good efficiency, however the energy required for heating must also be sufficient Amount are available. This requirement is only given when the electric current to the vehicle constantly is fed via contact wires or busbars. Such However, vehicles cannot be operated everywhere, only on specially equipped roads (trolleybus) or Railroad tracks (train).

Für leitungsunabhängige Fahrzeuge mit Elektroantrieb muß die für Heizung benötigte Energie in Form zusätzlicher Batteriekapazität im Fahrzeug selbst installiert werden. Dadurch werden zusätzliche Kosten und ein erhöhtes Fahrzeug­ gewicht verursacht, wodurch auch eine größere Motorleistung erforderlich werden kann. For line-independent vehicles with an electric drive the energy required for heating in the form of additional Battery capacity can be installed in the vehicle itself. This will result in additional costs and an increased vehicle causes weight, which also means greater engine power may be required.  

Aus der DE-AS 24 51 221 ist eine Luftheizung für ein Elektrofahrzeug bekannt. Diese Luftheizung besteht im wesentlichen aus einem Luftkanal, wobei die Akku­ mulatoren, eine Fremdwärmequelle und ein Gebläse, so angeordnet sind, daß ein Innenraum erwärmt werden kann. Dabei werden von der Wärmequelle aus zunächst die Akkumulatoren sowie die Regeleinrichtung und der Elektromotor erwärmt, wenn das Fahrzeug seinen Be­ trieb aufnimmt.From DE-AS 24 51 221 is an air heater for one Electric vehicle known. This air heating exists essentially from an air duct, the battery mulators, a source of external heat and a blower, are arranged so that an interior can be heated can. It starts from the heat source the accumulators as well as the control device and the Electric motor warms up when the vehicle is loading drifting takes up.

Im Betrieb wird dann zunächst ausschließlich die Wärmeabgabe der Akkumulatoren ausgenutzt. Da diese Wärmeabgabe nicht immer ausreicht, besteht die Mög­ lichkeit, auch die Regeleinrichtung und den Elektro­ motor in den Luftstrom mit einzubeziehen. Hierzu sind besondere Umschalteinrichtungen notwendig. Die Akkumulatoren können zusätzlich mit einem ört­ lichen Flüssigkeitskreislauf ausgestattet sein, der jedoch keinen unmittelbaren Einfluß auf den zu hei­ zenden Innenraum hat, sondern nur über den Luftkanal mit diesem in Verbindung steht.In operation, only the Heat emission from the batteries used. This one Heat is not always sufficient, there is a possibility the control device and the electrical system motor in the air flow. For this special switching devices are necessary. The accumulators can also with a local be equipped liquid circuit, the however no direct influence on the too hot inner space, but only through the air duct connected with this.

Die Aufgabe der Erfindung besteht darin, ein Wärme­ austauschsystem für die Heizung eines Straßenfahr­ zeuges mit Elektroantrieb vorzustellen, das insbeson­ dere bei batteriebetriebenen Fahrzeugen einsetzbar ist, wobei mit einem einfachen Wärmeaustauschsystem eine ausreichende Wirkung erzielt wird, ohne daß zu­ sätzliche Wärmequellen erforderlich sind und Umschalt­ einrichtungen notwendig sind, und wobei keine Erhöhung der Batteriekapazität zum Betreiben von Wärmekapazität erforderlich ist. The object of the invention is a heat exchange system for heating a road vehicle To present stuff with an electric drive, in particular can also be used in battery-powered vehicles is, with a simple heat exchange system a sufficient effect is achieved without Additional heat sources are required and switching facilities are necessary, and no increase the battery capacity to operate heat capacity is required.  

Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Patentanspruchs 1 gelöst.This object is achieved by the features of claim 1.

Damit wird in vorteilhafter Weise erreicht, daß die an den sich schnell erhitzenden Leistungshalbleitern, die zur Steuerung des Fahrmotors eingesetzt sind, entstehen­ de Wärme zu Heizzwecken genutzt werden kann, wobei gleich­ zeitig die besagten Leistungshalbleiter gekühlt werden. Weiterbildungen der Erfindung ergeben sich aus den Unter­ ansprüchen.This is advantageously achieved in that the the rapidly heating power semiconductors that are used to control the traction motor de heat can be used for heating purposes, being the same the said power semiconductors are cooled in good time. Further developments of the invention result from the sub claims.

Ein Ausführungsbeispiel der Erfindung wird nachstehend anhand einer Zeichnung näher erläutert. Es zeigtAn embodiment of the invention is shown below explained in more detail using a drawing. It shows

Fig. 3 Prinzipschaltung der wärmeabge­ benden Leistungshalbleiter. Fig. 3 basic circuit of the heat-giving power semiconductors.

Da durch den Thyristor Th und die Diode D1 ein hoher Strom fließt und dabei ein entsprechender Spannungsab­ fall entsteht, tritt an den beiden Halbleitern Th und D1 eine Verlustwärme auf. Das gleiche gilt auch für die Freilaufdiode D2 (siehe hierzu Prinzipschaltung Fig. 3). Die durch Verlustleistung erwärmte Flüssigkeit wird durch den Kühler über Schläuche in die Heizung des Fahrraumes gepumpt (siehe hierzu Fig. 2).Since a high current flows through the thyristor Th and the diode D 1 and a corresponding voltage drop occurs, a loss of heat occurs at the two semiconductors Th and D 1 . The same also applies to the freewheeling diode D 2 (see the basic circuit in Fig. 3). The liquid heated by power loss is pumped through the cooler through hoses into the heating of the driver's compartment (see Fig. 2).
