Abstract
Description
Die Erfindung betrifft eine elektrische Maschine mit einem Stator, der einen Kühlkreislauf mit einem flüssigen Kühlmittel aufweist.The invention relates to an electric machine with a stator having a cooling circuit with a liquid coolant.
Derartige elektrische Maschinen sind bekannt. Die Verlustwärme des Rotors der elektrischen Maschine wird dabei üblicherweise mittels eines Lüfters an den Kühlkreislauf abgegeben.Such electrical machines are known. The heat loss of the rotor of the electric machine is usually delivered by means of a fan to the cooling circuit.
Der Erfindung liegt die Aufgabe zugrunde, eine elektrische Maschine der oben genannten Art vorzuschlagen, die eine besonders effektive Wärmeabfuhr der Wärme des Rotors aufweist.The invention has for its object to propose an electric machine of the type mentioned above, which has a particularly effective heat dissipation of the heat of the rotor.
Die Aufgabe wird mit den Merkmalen nach Anspruch 1 gelöst.The object is achieved with the features of claim 1.
Dabei ist ein Rotor vorgesehen, der einen Thermosiphon mit einem Verdampfer und mit mindestens einem Kondensator aufweist. Der Kondensator ist zur Wärmeabfuhr der Rotorwärme an den Kühlkreislauf angeschlossen. Hiermit lässt sich eine besonders gute Wärmeabfuhr erreichen.In this case, a rotor is provided, which has a thermosiphon with an evaporator and with at least one capacitor. The condenser is connected to the cooling circuit for heat dissipation of the rotor heat. This allows a particularly good heat dissipation can be achieved.
Eine vorteilhafte Weiterbildung der elektrischen Maschine besteht, wenn gemäß Anspruch 2 der Kondensator mit Kühlrippen ausgeführt ist, die von einem Gehäuse mit einem Zulauf und einem Ablauf für das Kühlmittel umgeben sind.An advantageous development of the electric machine is when according to claim 2, the capacitor is designed with cooling fins, which are surrounded by a housing with an inlet and a drain for the coolant.
Über den Zulauf und Ablauf wird durch das Gehäuse flüssiges Kühlmittel hindurchgeleitet und von den Kühlrippen entsprechend der Differenztemperatur zum Kühlmittel Wärme abgeführt.About the inlet and outlet liquid coolant is passed through the housing and dissipated by the cooling fins according to the differential temperature to the coolant heat.
Außerdem ist es vorteilhaft, wenn gemäß Anspruch 3 die Kühlrippen des Kondensators fest mit der Welle des Rotors verbunden sind und eine dynamische Dichtung zwischen dem Kondensator und dem Gehäuse vorgesehen ist.Moreover, it is advantageous if according to
Weiterhin ist eine vorteilhafte Weiterbildung der elektrischen Maschine gegeben, wenn gemäß Anspruch 4 das Gehäuse mit zwei Gehäuseschalen ausgeführt ist, die über eine O-Ring-Dichtung miteinander verbunden sind.Furthermore, an advantageous development of the electric machine is given if according to
Die Kühlrippen können vorteilhaft fest mit dem Gehäuse verbunden werden, wenn gemäß Anspruch 5 der Kondensator mit den Kühlrippen feststeht und zur Welle des Rotors ein Spalt vorgesehen ist, der als Flüssigmetalllager ausgeführt ist.The cooling fins can advantageously be fixedly connected to the housing if according to claim 5, the capacitor is fixed to the cooling fins and the shaft of the rotor, a gap is provided, which is designed as a liquid metal bearing.
Eine besonders gute Wärmeabfuhr lässt sich erreichen, wenn gemäß Anspruch 6 die Welle des Rotors einen bis an die Enden der Welle reichenden Verdampfer aufweist, wobei an den beiden Enden der Welle jeweils ein Kondensator vorgesehen ist und die Kondensatoren jeweils an den Kühlkreislauf angeschlossen sind.A particularly good heat dissipation can be achieved if according to
