CA 2683455

The invention relates to a cooling-arrangement of an electrical machine. The inventive arrangement for cooling of an electrical machine comprises a rotor (R) and a stator (S), while an air-gap (AG) is between the rotor (R) and the stator (S). The rotor (R) and the stator (S) show arrangements (I, O, AS) to allow the circulation of air for cooling-purposes of the rotor (R) and of the stator (S). The rotor (R) and the stator (S) are encapsulated by a shell (S). The shell (S) is formed to allow the flow of hot air from the rotor (R) and the stator (S) to a heat-exchanger (HX) and where the shell (S) is formed to allow the flow of cool air from the heat-exchanger (HX) back to the rotor (R) and the stator (S) for cooling-purposes. The shell (S) show a number of corners (C), while each corner is used to gather the hot air before it is guided to the heat-exchanger (HX).
