摘要 |
The invention relates to a cooling-arrangement of an electrical machine. The inventive arrangement for cooling of an electrical machine comprises a rotor (1) and a stator (2) of the electrical machine, while an air-gap (AG) is between the rotor (1) and the stator (2). The electrical machine (G) comprises an air-cooling-arrangement (7), which circulates air inside the electrical machine (G). The electrical machine (G) comprises an liquid-cooling-arrangement (8,9,10,11,12), which circulates cooling-liquid (12) inside the electrical machine (G). The air-cooling arrangement (7) and the liquid-cooling-arrangement (8,9,10,11,12) are connected by an air-to-liquid heat-exchanger (8), which is applied to transport heat out from the electrical machine (G) by the cooling-liquid.
