Background technique
In teeth in synchronous generator calculating, the heat dissipation design of winding is the extremely important part of design of generator, and winding dissipates
The quality of thermal effect directly influences the temperature rise of winding, influences reliability, the economy of generator.Using air cooled hair
Motor is generally equipped with a main fan in one end of generator amature, so that air is entered power generation from one end of generator by fan
Inside machine, by the stator surface of generator, rotor surface, heat that generator unit stator, rotor are generated is from the another of generator
One end is taken out of, achievees the purpose that stator winding, rotor windings heat dissipation.The generator to radiate in this way, air are only and fixed
Sub- iron core, rotor core, stator winding, rotor windings appearance face contact, air not can enter stator core, rotor core, determine
The inside of sub- winding, rotor windings, therefore contact area is small, heat dissipation effect is poor.Cooling air enters from one end of generator, separately
One end output, it is uneven to generator winding heat dissipation effect, will cause generator windings temperature highest and it is minimum between one
As differ 30K to 40K.And we to generator carry out winding temperature rise test measurement be winding average temperature rising, average temperature rising
Often winding a part can be more than the requirement of national standard when qualified, and the reliability of such generator can reduce.
Utility model content
In view of the deficiencies of the prior art, the utility model is intended to provide a kind of generator of multiple fans, has structure letter
Advantage single, small in size, easy to use；Increase stator core, rotor core, stator winding, rotor windings heat dissipation area,
The heat dissipation effect for improving generator reduces the temperature difference between stator winding, the temperature difference between rotor windings.
The utility model is achieved through the following technical solutions.
A kind of generator of multiple fans, including engine block, engine block are equipped with main fan, rotor core, determine
Sub- iron core, rotor windings, stator winding, base, rear end cap are equipped with multiple interior wind in the duct-ventilated rotor core in yoke portion
It fans, stator ventilating board identical and one-to-one with internal fan quantity, mutual corresponding stator ventilation is installed in stator core
Plate and internal fan are axially aligned, and main fan is mounted on the main shaft of engine block, and air-intake window and air outlet window are provided on base
Mouthful, air inlet hole is provided on rear end cap.
Preferably, internal fan is mounted on inside rotor core.
Compared with prior art, the utility model has the advantages that: the utility model have structure it is simple, it is small in size, use
Convenient advantage；The utility model can make cold air enter rotor core, stator core, rotor windings, stator winding it is interior
Portion, increase rotor core, stator core, rotor windings, stator winding heat dissipation area, improve rotor core, stator iron
The heart, rotor windings, stator winding heat dissipation effect.It is excessively high for stator winding, rotor windings a part temperature, it can be to excessively high portion
Position increases the air quantity of internal fan, achievees the purpose that reduce the temperature difference between stator winding, the temperature difference between rotor windings, improves
Reliability, the economy of generator.
