Abstract

In the heat exchange system according to the invention, the power semiconductors necessary to control the driving motor are cooled with liquid, the cooling connections thereof being connected, via a closed pipe system, to a pump and to a heating installation which is located in the vehicle interior and which gives off heat. The whole system is filled with an insulating liquid which is circulated by the pump, heat being removed from the power semiconductors and supplied to the heating installation.

Description

Wärmeaustauschsystem für die Heizung eines Straßen- Heat exchange system for heating a street

fahrzeuges mit Elektroantrieb Die Erfindung betrifft einWärmeaustauschsystem für die Heizung eines Straßenfahrzeuges mit Elektroantrieb,wobei zur Steuerung des Fahrmotors Leistungshalbleiter eingesetzt werden,die sich beim Fahrbetrieb stark erwärmen. Electric Drive Vehicle The invention relates to a heat exchange system for heating a road vehicle with an electric drive, whereby to control the Drive motor's power semiconductors are used, which are strong when driving heat.

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 Indoor heating to 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 Fahreug ständig über Fahrdrähte oder Stronachienen zugeführt wird.Derartige Fahrzeuge sind aber nicht überall betreibbar, sondern nur auf besonders dafür eingerichteten Straßen (0-Bus) oder Schienenstreckow (Bahn).This results in a very good efficiency, but must The energy required for heating is also available in sufficient quantities The prerequisite is only given if the electric current is constantly flowing to the vehicle is supplied via contact wires or Stronachienen. Such vehicles are cannot be operated everywhere, but only on roads specially designed for this purpose (0 bus) or Eisenbahnstreckow (train).

Für leitungsunabhängige Fahrzeuge mit Elektroantrieb iruß die für Heizung benötigte Energie in Form zusätzlicher Batteriekapazität im Fahrzeug selbst installiert werden.For line-independent vehicles with electric drive, the for Heating required energy in the form of additional battery capacity in the vehicle itself to be installed.

Dadurch werden zusätzliche Kosten und ein erhöhtes Fahrzeuggewicht verursacht,wodurch auch eine größere Motorleistung erforderlich werden kann.This creates additional costs and an increased vehicle weight caused, whereby a larger engine power can be required.

Die Aufgabe der Erfindung besteht darin,ein Wärmeaustauschsystem für die Heizung eines Straßenfahrzeuges mit Eletroantrieb vorzustellen,das insbesondere bei batterie-betriebenen Fahrzeugen einsetzbar ist,ohne daß eine Erhöhung der Batteriekapazität notwendig ist.The object of the invention is to provide a heat exchange system for to introduce the heating of a road vehicle with electric drive, in particular can be used in battery-operated vehicles without increasing the battery capacity necessary is.

Diese Aufgabe wird mit Merkmalen gelöst,wie sie im Patentanspruch 1 angeben sind.This object is achieved with features as described in the patent claim 1 must be specified.

Damit wird in vorteilhafter Weise erreicht, daß die an den sich schnell erhitzenden Leistungshalbleitern, die zur Steuerung des Fahrmotors eingesetzt sind,entstehende Wärme zu Heizzwecken genutzt werden kann,wobei gleichzeitig die besagten Leistungshalbleiter gekühlt werden.This is achieved in an advantageous manner that the quickly heating power semiconductors that are used to control the traction motor Heat can be used for heating purposes, at the same time said power semiconductors be cooled.

Weiterbildungen der Erfindung:.ergeben sich aus den Unteransprüchen.Developments of the invention: emerge from the subclaims.

Ein Ausführungsbeispiel der Erfindung wird nachstehend anhand einer Zeichnung näher erläutert.An embodiment of the invention is described below with reference to a Drawing explained in more detail.

Es zeigt: Fig la Seitenansicht des Kühlkörpers mit elektrischen Anschlüssen und Schlauchstutzen. It shows: Fig la side view of the heat sink with electrical connections and hose connector.

Fig 1b Draufsicht- Dioden-Thyristor block mit Kühlkörpern und Verschraubung Fig 2 Das gesamte Wärmeaustauschsystem im Prinzip Fig 3 Prinzipschaltung der wärmeabgebenden Leistungshalbleiter Da durch den Thyristor Th und die Diode D1 ein hoher Strom fließt und dabei ein entsprechender Spannungsabfall entsteht,tritt an den beiden Halbleitern Th und D1 eine Verlustwärme auf.Das gleiche gilt auch fUr die Freilaufdiode D2 (siehe hierzu Prinzipschaltung Fig 3) Die durch Verlustleistung erwärmte Flüssigkeit wird durch denKUbkr über Schläuche in die Heizung des Fahrraumes gepumpt (siehe hierzu Fig 2) - Leerseite - Fig 1b plan view diode thyristor block with heat sinks and screw connection Fig 2 The entire heat exchange system in principle Fig 3 Schematic circuit of the heat emitting Power semiconductors Since a high current flows through the thyristor Th and the diode D1 and a corresponding voltage drop occurs in the two semiconductors Th and D1 generate a loss of heat. The same applies to the freewheeling diode D2 (see basic circuit diagram Fig 3) The liquid heated by power dissipation is pumped through the KUbkr via hoses into the heating of the driving area (see Fig 2) - blank page -
