Multiple slot for windings 201 in, therefore the position of condenser 1 is higher than the position of each cooling tube 2, the input end of condenser 1, outlet
End, can be connected to the top of first annular pipe 3 and the second ring pipe 4, and the cooling working medium of steam state can be natural in cooling tube 2
Ground is backed up in condenser 1, and liquid cooled working medium can flow downwardly into naturally in cooling tube 2 in condenser 1.
Optionally, in winding assembly provided by the embodiments of the present application, first annular pipe 3 and the second ring pipe 4 are set respectively
Set the both ends axial in iron core 200.
The shape of first annular pipe 3 and the second ring pipe 4 is adapted with the shape of 200 end of iron core, avoids occupying excessive
Space, ensure that the compactedness of winding assembly structure.
Based on the same inventive concept, the embodiment of the present application also provides a kind of generators, including the embodiment of the present application to provide
Winding assembly.
Based on the same inventive concept, the embodiment of the present application also provides a kind of wind power generating sets, including the application to implement
The generator that example provides.
Using embodiments herein, following technical effect at least may be implemented:
In cooling device provided by the embodiments of the present application, cooling tube setting can be bonded in slot for winding with winding, and
The size for not obviously increasing iron core itself ensure that the compactedness of electric machine structure.
In addition, become steam state after the heat of the cooling working medium absorption winding of liquid in cooling tube and flow back into condenser, it is cold
After condenser absorbs the heat of the cooling working medium of steam state, the cooling working medium that the cooling working medium of steam state is converted to liquid again flows into cooling
In pipe.Above process circulation carries out, and the heat of motor is taken away, and realizes the heat dissipation to motor.It is dissipated compared to air-cooled and liquid cooling
Hot mode, cooling device provided by the embodiments of the present application are radiated using the evaporation cooling of cooling working medium, improve motor
Safety and the feature of environmental protection.
Moreover, because cooling tube is arranged except winding, it is two independent components with winding, the shape of cooling tube is endless
It is limited entirely by winding shape, the bending section of mutation can be avoided the occurrence of when designing the shape of cooling tube, on the one hand can be guaranteed
The smoothness that cooling working medium flows in cooling tube guarantees the uniform flow for cooling down working medium in cooling tube everywhere, on the other hand may be used
Vortex is formed in cooling tube to avoid cooling working medium, and then avoids the occurrence of local head loss, guarantees the peace of the heat dissipation of motor
Full reliability.
