First, supply with by the external power of the external power source from not shown, drive inner air blast 44 (air blast motor 44c) and external blower 43.Thus, as shown in Figure 4, in framework (body framework 11 and unit framework 41) inside, the suction unit 44a below inner air blast 44 aspirates inner air upward, sends inner air from the exhaust portion 44b of inner air blast 44 peripheral parts to horizontal direction outside simultaneously.
Now, as shown in Figure 5, inner air in the circulation of air space 22b of rotor 20 inner face side is by the suction from suction unit 44a, the mainly rotor ventilation hole 26 through rotor 20 upsides (the first half) position along arrow C 1 direction, mobile (rising) is to the air gap part of rotor 20 peripheral parts (the interior perimembranous of stator 30).Because rotor 20 rotates by the rotating shaft 21 being connected with blade 4 (with reference to Fig. 1), therefore the inner air in rotor ventilation hole 26 changes along with the rotation of rotor 20 through position.In the present embodiment, because rotor ventilation hole 26 is upper along circumferentially extending at roughly all-round (except the rib 23) of rotor 20, therefore irrelevant with the anglec of rotation of rotor 20, inner air can pass through rotor ventilation hole 26 all the time.
And, owing to being arranged with multiple rotor ventilations hole 26 in the axial roughly total length of rotor 20, therefore inner air can be at axially (directions X) thus both ends and central portion there is uneven peripheral part (air gap part) entirety that flows into rotor 20.In this air gap part, inner air contacts with the peripheral part (surface of permanent magnet 22a) of rotor 20, the interior perimembranous (the tooth portion between winding 32 and winding 32) of stator 30, carries out cooling to above-mentioned each portion.Thus, in the interior perimembranous (air gap part) of peripheral part and the stator 30 of rotor 20, the pyrotoxin of generator 1 is that near the periphery position (tooth portion between groove 31b, permanent magnet 22a) of winding 32 and winding 32 is by effectively cooling.In addition, also flow into slightly inner air from the air gap part of axial (directions X) end of rotor 20 and stator 30.
Next, by the suction from suction unit 44a, inner air moves along air gap part arrow C 2 directions upward, and the stator ventilation hole 36 of process stator 30.As shown in Figure 4, because stator 30 is fixed by supporting clapboard 13, therefore inner air mainly passes through the stator ventilation hole 36 of stator 30 the first half upward.And as shown in Figure 6, in stator ventilation hole 36 inside, the winding 32 that (directions X) extends vertically exposes from stator core 31 (stator core portion 33).Therefore, inner air, when through stator ventilation hole 36, utilizes inner air through between winding 32, and in winding 32 outer surfaces roughly all-round, carries out cooling.Thus, cooling pyrotoxin is that winding 32 exposes the part in stator ventilation hole 36 inside effectively.
(arrow C 2 directions) flow out to the outer peripheral face of stator 30 (stator core 31) through the inner air of stator ventilation hole 36 upward.Owing to being arranged with the circumferentially stator ventilation hole 36 of extension of multiple edges in the axial roughly total length of stator 30, therefore inner air flows out from the roughly entirety (except the part of connecting elements 34) of the outer peripheral face of stator 30 the first half.Therefore, the outer peripheral face of stator 30 is also by effectively cooling.
And as shown in Figure 4, the inner air that has absorbed the heat of rotor 20 and stator 30 flows to the top of stator 30, flow into the air-breathing path of the trapezoidal quadrangular pyramid shape being surrounded by the 1st tilt clapboard the 45, the 2nd tilt clapboard 46 and horizontal baffle 47.Owing to disposing a lot of cooling water pipes 42 in this space, therefore inner air is through the peripheral part of above-mentioned cooling water pipe 42, and along arrow C 3 directions (with reference to Fig. 4 and Fig. 5), suction unit 44a upward moves.Now, because the air-breathing path of trapezoidal quadrangular pyramid shape is configured to the size (size of peristome 47a) that approaches suction unit 44a, therefore in the air-breathing path of this trapezoidal quadrangular pyramid shape, inner air can not hinder mobilely because of viscous flow, and inner air flows into suction unit 44a swimmingly.
In each cooling water pipe 42, utilize and supply with and driven external blower 43 by external power, the extraneous air of low temperature (temperature is lower than inner air) flows to the other end along arrow D direction from one end.When inner air moves through each cooling water pipe 42, between the inner air after the extraneous air of the low temperature in cooling water pipe 42 and heat absorption, heat exchange occurs, inner air is cooled.Thus, during inner air flows into suction unit 44a, the heat that inner air absorbs from rotor 20 and stator 30 is emitted to outside.
The inner air flowing into after suction unit 44a is sent to horizontal direction outside along arrow C 4 directions from exhaust portion 44b by inner air blast 44.Thus, inner air is sent to exhaust pathway.The inner air of sending from exhaust portion 44b declines and flows in body framework 11 along arrow C 5 directions between the 1st tilt clapboard 45 and the inwall of unit framework 41.Now, because inner air passes through between a lot of cooling water pipes 42 again, therefore inner air is cooled again.
Aspirated by suction unit 44a in by the follow-up pushing of the air-flow from exhaust portion 44b through the inner air flowing between cooling water pipe 42 in body framework 11, thereby in the circulation of air space 22b of inflow rotor 20 inner sides (moving along arrow C 6 directions).Thus, the inner peripheral surface of rotor 20 (rotor core 22) is cooling by inner air.Thereafter, be used to the suction of the 44a of Self inhaling portion, inner air flows into rotor ventilation hole 26 (arrow C 1 direction) again.So, form the circular flow of inner air to connect the mode of arrow C 1～C6.Thus, comprise that pyrotoxin is that the interior perimembranous of the stator 30 of winding 32, the peripheral part of stator 30, interior perimembranous and the peripheral part of rotor 20 are cooled by the circular flow of inner air.
In the present embodiment, as mentioned above, by the rotor ventilation hole 26 that is through to outer peripheral face from the inner peripheral surface of rotor 20 being arranged to the rotor 20 of generator 1, the stator ventilation hole 36 that is through to outer peripheral face from the inner peripheral surface of stator 30 is arranged to the stator 30 of generator 1 simultaneously on the position corresponding to rotor ventilation hole 26, not only can be via the stator ventilation hole 36 of the rotor ventilation hole 26 of rotor 20 and stator 30 the peripheral part air supply to stator 30, can also be to the interior perimembranous air supply of stator 30.Thus, can effectively carry out cooling to the stator 30 with pyrotoxin.And, owing to can also supplying air to via the stator ventilation hole 36 of the rotor ventilation hole 26 of rotor 20 and stator 30 peripheral part and the interior perimembranous of rotor 20, therefore can also effectively carry out cooling to rotor 20.
And, in the present embodiment, as mentioned above, in axial (directions X) upper multiple rotor ventilations hole 26 that arranges spaced apart of rotor 20, multiple stator ventilation holes 36 are set on the position corresponding to multiple rotor ventilations hole 26 simultaneously.By formation like this, by multiple rotor ventilations hole 26 and multiple stator ventilation hole 36 flow into separately inner air, can axially (directions X) on a large scale in carry out cooling to rotor 20 and stator 30.
And in the present embodiment, as mentioned above, rotor ventilation hole 26 is set to the circumferential extension along rotor 20, stator ventilation hole 36 is set on the position corresponding to rotor ventilation hole 26 along circumferentially extending.Thus, can carry out cooling to rotor 20 and stator 30 on a large scale circumferential.Especially can be upper with the circle-shaped rotor ventilation hole 26 that arranges by roughly all-round (except the position of rib 23) at the rotors 20 of 21 rotations around the shaft, and independently make all the time inner air inflow rotor ventilation hole 26 with the position of rotation of rotor 20.Thus, can more effectively carry out cooling to rotor 20 and stator 30.
And, in the present embodiment, as mentioned above, the rotor core 22 of rotor 20 is made up of multiple ring-type rotor core portion 24 spaced apart along rotor shaft direction (directions X) and configuration, forms rotor ventilation hole 26 by the space between multiple rotor core portion 24.Thus, can be easily in rotor 20 roughly all-round, form rotor ventilation hole 26, its interior perimembranous from rotor 20 (inner peripheral surface of cylindric rotor core 22) is through to the peripheral part of rotor 20.
And, in the present embodiment, as mentioned above, multiple ring-type stator core portion 33 spaced apart by the rotor shaft direction along rotor 20 (directions X) and configuration forms stator 30 (stator core 31), forms stator ventilation hole 36 by the space between multiple stator core portion 33.Thus, can be easily in the roughly all-round upper formation of stator 30 (stator core 31) corresponding to the stator ventilation hole 36 in rotor ventilation hole 26.
And, in the present embodiment, as mentioned above, between multiple rotor core portion 24, dispose rotor partition 25, between multiple stator core portion 33, dispose stator partition 35.Thus, if make rotor partition 25 identical with the thickness of stator partition 35, can easily make the position in the rotor ventilation hole 26 being formed by the space between multiple rotor core portion 24 and the position consistency of the stator ventilation hole 36 that formed by the space between multiple stator core portion 33.Therefore, owing to forming ventilation hole by rotor ventilation hole 26 and stator ventilation hole 36, run through rotor 20 and stator 30 along radial direction with linearity, therefore can make inner air easily pass through.Its result, can make the circulation of inner air increase, and more effectively carries out cooling.
And in the present embodiment, as mentioned above, circulation of air space 22b is made up of the space being surrounded by the inner peripheral surface of cylindrical rotor 20.By formation like this, can easily form vertically the circulation of air space 22b that (directions X) runs through rotor 20 inside.And 22b runs through rotor 20 vertically by circulation of air space, can make the inner air inflow amount (throughput) that flows to rotor 20 interior perimembranous increase.Its result, can more effectively carry out cooling to the interior perimembranous of rotor 20.
And, in the present embodiment, as mentioned above, be provided with the framework (body framework 11 and unit framework 41) and the cooling unit 40 that contain stator 30 and rotor 20.And, between the rotor ventilation hole 26 of rotor 20 and the stator ventilation hole 36 of stator 30 and cooling unit 40, being provided with inner air blast 44, its formation makes the circular flow of the inner air circulation of framework (body framework 11 and unit framework 41).Thus, by make inner air circulation between rotor ventilation hole 26 and stator ventilation hole 36 and cooling unit 40, can the heat absorbing from rotor 20 and stator 30 be emitted to cooling unit 40 via rotor ventilation hole 26 and stator ventilation hole 36.
And in the present embodiment, as mentioned above, inner air blast 44 is configured to by external power to be supplied with and is driven, and forms forcibly circular flow.At this, for wind generator system, compared with other generation mode, the impact of weather etc. is larger, and the rotating speed deviation of rotating shaft 21 is larger.Therefore, for example, by with the axial flow fan of rotating shaft one rotation during for inner air blast, the air quantity producing while existing the rotating speed of rotating shaft lower tails off, and coolingly becomes inadequate situation.In the present embodiment, supply with to drive inner air blast 44 by external power, thereby can not be subject to the impacts such as the rotating speed of rotating shaft 21, can carry out all the time stable cooling.
