Description
Technical field
This utility model relates to a kind of wind-driven generator, especially relates to a kind of low noise environmental protection type directly-driven wind
Electromotor.
Background technology
At present, domestic wind-driven generator produce product, be mainly used in low altitude area hinterland, home and abroad and
The large-scale wind field of coastal area.The scale that is mainly characterized by of its wind field is big, away from resident living area, the most right
Less demanding in terms of environmental protection, noise of wind power generating set.On the one hand, due on American-European international market,
Sizable wind-powered electricity generation potential customers are scattered private farmer, on the other hand along with domestic big wind energy turbine set money
Source is the most exhausted, and wind-power market can slowly move towards the development trend of the small-scale wind field closer to cities and towns, these
Wind field is owing to closer to intensive residential block, needing low noise environmental protection type wind power generating set to replace existing product
Product.
The dominant noise source of existing wind-driven generator product from two aspects, one, mechanical blowing rubs noise: its
Including the fricative noise of bearing of wind power generator, rotor rotate time with windage time produce noise and
Forced ventilation cooling system high-power blower noise these three aspect.The first two aspect is rubbed at whole mechanical blowing and is made an uproar
In source of sound, put share is little, and is difficult to eliminate, therefore reduce noise it is crucial that eliminate forced ventilation system
System noise.Two, electromagnetic noise: it produces mainly due to the higher harmonic components in motor internal electromagnetic field
Caused.Higher harmonic components is mainly derived from the slot ripples that motor slot effect produces.
Utility model content
The purpose of this utility model is to provide a kind of low noise environmental protection type direct wind-driven generator, and it has makes an uproar
Sound is low, perfect heat-dissipating and cost-effective feature, upper with solve that prior art wind electromotor exists
State problem.
For reaching this purpose, this utility model by the following technical solutions:
A kind of low noise environmental protection type direct wind-driven generator, it includes rotor assembly and is arranged at described rotor set
Stator module outside part, wherein, described stator module includes out frame and several stator coils, institute
State stator coil and all use hollow flat type copper wire coiling, in described stator coil, be all passed through change suppression heat conduction medium,
And each stator coil is all connected with collecting pipe, described collecting pipe and a hollow heat sink are connected.
Especially, described rotor assembly includes that rotor magnetic pole, described rotor magnetic pole are in tilted layout, itself and motor
There is angle α in axis, cuts down slot ripples component to greatest extent, thus reduce electromagnetic noise.
Especially, described hollow heat sink is fixed on the outer ring of described out frame, is directly exposed to air
In, described collecting pipe is connected through described out frame with hollow heat sink.
Especially, described angle α=4.4 °.
Especially, described hollow heat sink uses any one of aluminium sheet or copper coin.
The beneficial effects of the utility model are, the most described low noise environmental protection type directly-driven wind is sent out
Motor has the advantage that
1) fall below less than 80 decibels through overtesting this new construction motor noise from 120 decibels, meet
User's requirement to motor noise；
2) stator temperature rise is from 78K, falls below 65K, can improve greatly stator winding insulation service life, also be
Material-saving potentiation from now on provides bigger space；
3) save the input costs such as blower fan, reduce unit weight, be more conducive to install.

Detailed description of the invention
Further illustrate the technical solution of the utility model below in conjunction with the accompanying drawings and by detailed description of the invention.
Refer to shown in Fig. 1 to Fig. 3, in the present embodiment, a kind of low noise environmental protection type direct wind-driven generator
Including rotor assembly 1 and the stator module 2 outside being arranged at described rotor assembly 1, described stator module 2 wraps
Including out frame 3 and several stator coils 4, described stator coil 4 all uses hollow flat type copper wire coiling, and
Each stator coil 4 all welds connection, described collecting pipe 5 and hollow heat-dissipating aluminium plate 6 phase with collecting pipe 5
Connection, described hollow heat-dissipating aluminium plate 6 is fixed on the outer ring of described out frame 3, is directly exposed to air
In, described collecting pipe 5 is connected through described out frame 3 with hollow heat-dissipating aluminium plate 6.Described stator line
The connected network of circle 4, collecting pipe 5 and hollow heat-dissipating aluminium plate 6 composition is passed through change suppression heat conduction medium, this matchmaker
Jie is a kind of gaseous state type material, its characteristic be can by the microcirculation of self keep everywhere homogeneous temperature, one
Cause.Therefore, after heater and radiating element pass through pipeline connection and be packed into this heat conduction medium, can send out
The heat of hot body is transmitted to radiating element and radiating and cooling efficiently.
When motor runs, the heat that stator winding 2 produces passes to the hollow outside support by heat conduction medium and dispels the heat
On aluminium sheet 6 and be dispersed in air, it is achieved the noiselessness high efficiency motor type of cooling.
