Abstract
The invention relates to a wind guide device of a direct-drive wind power generator. The wind guide device comprises a wind guide hood I, a wind guide hood II, a wind guide hood III and a wind guide hood IV. The wind guide hood I which is gradually contracted along wind direction is arranged at the right end of the stator of the power generator. The convex wind guide hood IV and the wind guide hood II formed by a gradually contracted section and a curved section are respectively and symmetrically arranged at the left end and the right end of the stator of the power generator. The wind guide hood II which is formed by two curved sections and a supporting section and is matched with the wind guide hood II to form a curved runner is arranged on the rotor support I of the power generator. Through using the wind guide hoods to change the flowing state of wind, the invention has the advantages that the ventilation cooling system in the power generator set is simplified, the cooling efficiency of the wind power generator is improved, the reliability of the wind power generator is improved and the manufacturing cost of the wind power generator is reduced.
Description
Technical field
The present invention relates to a kind of wind-guiding device, more particularly, relate to a kind of wind guide device of direct-drive wind power generator.
Background technique
For direct wind-driven generator, heat dissipation problem is very crucial, and particularly, along with the develop rapidly of wind generating technology, the single-machine capacity of wind power generating set is increasing in recent years, and heat dissipation problem becomes the bottleneck that restriction wind power generating set power increases.
The existing generator outside (refers to generator amature for outer rotor generator; For the internal rotor generator, refer to generator unit stator) be processed with radiating fin; Cooling unit is equipped with in wind power generating set inside; Be generally cooling blower, the acting in conjunction through above-mentioned dual mode comes to dispel the heat to wind power generating set.When the power of unit increases, there is the generator of radiating fin to compare with undressed, the heat loss increase of generator that is processed with radiating fin is bigger; In order to walk the loss torrid zone; Just must like this, not only increase the blower fan manufacture cost at the inner ventilation cooling system that increases complicacy of unit; And increased the fault point of blower fan, thereby reduced the functional reliability of blower fan.
Someone once proposed the imagination of utilizing natural wind that wind power generating set is cooled off fully, still, cooled off if only simply natural wind is introduced blower fan, did not often reach expected effect.
Summary of the invention
The objective of the invention is to overcome the defective that above-mentioned technology exists, a kind of wind guide device of direct-drive wind power generator that can effectively improve whole blower fan cooling performance is provided.
The present invention realizes through following technical proposals: it comprises wind scooper I, wind scooper II, wind scooper III, wind scooper IV; Be located at the stator right-hand member of generator along the wind scooper I of wind direction convergent; Convex wind scooper IV, the wind scooper II that is made up of a converging transition and a curved section are symmetrically set in the stator support right ends of generator respectively, are constituted and are cooperated the wind scooper III that forms the curvilinerar figure runner to be located on the rotor supports I of generator with the wind scooper II by two curved sections and a supporting section.
The present invention changes the flowing state of wind through wind scooper; Natural wind is carried out secondary distribution; Actual demand according to each cooling duct distributes air quantity, has simplified the inner ventilation cooling system of unit, has improved the cooling effectiveness of wind-driven generator; Increase the reliability of wind power generator, reduced the manufacture cost of wind power generator.
Description of drawings
Fig. 1 is an overall structure schematic representation of the present invention;
Fig. 2 is a cooling air duct schematic representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing the present invention is further described.
With reference to Fig. 1, present embodiment comprises wind scooper I 4, wind scooper II 7, wind scooper III 8, wind scooper IV 35; Be located at stator 1 right-hand member of generator along the wind scooper I 4 of wind direction convergent; Convex wind scooper IV 35, the wind scooper II 7 that is made up of a converging transition and a curved section are symmetrically set in stator support 29 right ends of generator respectively, are constituted and are cooperated the wind scooper III 8 that forms the curvilinerar figure runner to be located on the rotor supports I 31 of generator with wind scooper II 7 by two curved sections and a supporting section.
The present embodiment working principle is following:
With reference to Fig. 2, natural wind gets into the cooling channel I 33 on the generator unit stator 1 under the guiding of wind scooper I 4, stator 1 outside is cooled off; Because wind scooper I 4 is a convergent along wind direction, thereby help increasing the flow velocity of the wind that gets into cooling channel I 33 (cooling channel I 33 is formed by the cavity between stator 1 and covering I 2 and the stator support 29); Natural wind cooperates under the guiding of the curvilinerar figure runner that constitutes in wind scooper II 7 and wind scooper III 8; The entering generator is inner; Form wind path III 23 and wind path IV 27; Wind path III 23 is taken away the heat of rotor iron core 16 generations through the cooling channel II 32 on the rotors 30 (cooling channel II 32 is formed by the inwall of rotor 30 and the cavity be located between the inboard covering II 17 of rotor 30), passes through the surface of wind scooper IV 35 again, enters in the atmosphere through the through hole I of being located on the stator support 29 18 at last; Wind path IV 27 is cooled off through 15 pairs of tapers supports 13 of through hole III of being located on the rotor supports I 31; The heat that produces in the wheel hub 21 is taken away; Form 28 pairs of further coolings of tapers support 13 of wind path VI through the through hole II of being located on the brake hoop 12 14 then, enter in the atmosphere through through hole I 18 again; Natural wind gets into the tapered channels that is made up of wind scooper III 8 and wheel hub 21 outer walls under the guiding of wind scooper III 8, main bearing outer ring I 9 and main bearing outer ring II 10 are cooled off.
More than be one embodiment of the present invention, a preferred example.The scope that patent application of the present invention is asked for protection has more than and is limited to said mode of execution.All technological schemes with the present embodiment equivalence all belong to protection scope of the present invention.
