Abstract
The present disclosure relates to a cooling system, an electric motor and a wind-power electric generator set. The cooling system is applied to an electric motor; the electric motor includes a stator support and a rotor support, the stator support is dynamically sealingly connected to the rotor support to form ventilation chambers respectively arranged at two ends of the electric motor in an axial direction, first ventilation holes are formed at two ends of the stator support in the axial direction respectively, and the cooling system includes: a flow-confluence chamber, arranged in a circumferential direction of the stator support; an accommodating chamber, arranged in the circumferential direction of the stator support; a heat exchanger, arranged in the accommodating chamber or in the flow-confluence chamber; a circulating fan, arranged in the circumferential direction of the stator support and located at a side of the stator support in the axial direction.
