In, identical label represents identical component all the time.
Fig. 1 is the signal for showing the cooling system for wind power generating set according to one embodiment of the present utility model
Figure.Fig. 2 is the top view for the deflector for showing the cooling system in Fig. 1.
As shown in figure 1, wind power generating set may include wheel hub 110, the kuppe 120 for being arranged on the outside of wheel hub 110, installation
The parts such as blade 130, engine room cover 140, pylon (not shown) on wheel hub 110.Kuppe 120 is the outer cover of wheel hub 110,
Pneumatic effect, protection wheel hub 110 are played in wind power generating set and for operation maintenance personnel disengaging wheel hub 110.The inside of wheel hub 110
For hollow-core construction, for installing variable blade control system, such as pitch control cabinet, pitch motor.The front end of wheel hub 110 can be formed with
Wheel hub entrance 110a, the entrance of wheel hub 110 is entered as operation maintenance personnel or commissioning staff.
Air inlet may include according to the cooling system for wind power generating set of one embodiment of the present utility model
120a, air outlet and deflector 150.Air inlet 120a may be formed at the front end of the kuppe 120 of wind power generating set.Deflector
150 are installed on kuppe 120 at air inlet 120a inner side preset distance.
The front end of kuppe 120 of the prior art is typically provided with water conservancy diversion cover opening, and the water conservancy diversion cover opening is generally by baffle plate
Block.In this case, the existing water conservancy diversion cover opening can be used as air inlet 120a, without in addition on kuppe 120
Open up air inlet.
Air outlet may be formed in kuppe 120 and/or engine room cover 140, but not limited to this.In order to avoid in kuppe
120 and/or engine room cover 140 on open up air outlet so as to reduce the manufacturing cost of wind power generating set, air outlet can be water conservancy diversion
Existing gap on cover and/or in engine room cover with ft connection.For example, in the present embodiment, air outlet may include the first air-out
Mouth 120b and/or the second air outlet 120c.First air outlet 120b may be formed between the root of kuppe 120 and blade 130,
Specifically, because blade 130 is through the blade mounting hole (not shown) of kuppe 120 and on wheel hub 110, therefore blade
Space is formed between 130 and blade mounting hole, the space can be used as the first air outlet 120b.Second air outlet 120c may be formed at
Kuppe 120 and the junction of engine room cover 140, specifically, because kuppe 120 is with the rotation of wheel hub 110 and relative to machine
Hatch cover 140 rotates, therefore kuppe 120 and the junction of engine room cover 140 are also formed with space, and the space can be used as the second air-out
Mouth 120c.
Deflector 150 can be connected to kuppe 120 by connector 151.Deflector 150 can be located at air inlet 120a and wheel
Between hub entrance 110a, and preset distance is separated along the axial direction of wheel hub 110 and wheel hub entrance 110a.Deflector 150 can block
Wheel hub entrance 110a front side, to prevent extraneous air or rainwater etc. to be fed directly in wheel hub 110, while wind is prevented to be blown into wheel
Hub 110.In the case where existing kuppe has water conservancy diversion cover opening and blocks the baffle plate of the water conservancy diversion cover opening, original can be removed
The installation screw of existing baffle plate can be used directly in some baffle plates, deflector 150, is pacified by three or more connectors 151
It is attached on kuppe 120, without transforming kuppe 120.
In the present embodiment, referring to Figures 1 and 2, deflector 150 can be arc surface shape and structure, and its lateral surface is convex
Face and medial surface are concave surface.Deflector 150 can block wheel hub entrance 110a front side, and the tangent line at the edge of deflector 150
Can be substantially tangent with wheel hub entrance 110a edge.Due to deflector 150 be in towards air inlet 120a protrude circular arc planar, because
, when air flow to deflector 150 from air inlet 120a, the direction of air is changed for this, and then air is along deflector 150
Outer surface continue to flow, finally by between the root of blade 130 and kuppe 120 the first air outlet 120b arrange
Go out.
In addition, deflector 150 and connector 151 are alternatively arranged as operation maintenance personnel or commissioning staff enters the auxiliary of wheel hub 110
Part, and in order to prevent operation maintenance personnel or commissioning staff from being scratched by deflector 150, the outward flange of deflector 150 may be provided with anti-
Guard ring (not shown).
Although deflector 150 is shown in Fig. 1 and Fig. 2 in circular arc planar and is connected to water conservancy diversion by three connectors 151
Cover 120, but the quantity not limited to this of the shape of deflector 150, link position and connector 151, for example, deflector 150 is also
Can trapezoidal, taper or other suitable shapes, as long as deflector 150 can change the direction of air and in wheel hub entrance
Low-pressure area (being described in detail below) is formed around 110a, deflector 150 can also be connected to wheel hub by connector 151
110, or deflector 150 can also be connected to both kuppe 120 and wheel hub 110, and deflector by connector 151
150 can be attached using any amount of connector 151 as needed.
For the ease of understanding the cooling system for wind power generating set according to embodiment of the present utility model, below will
Reference picture 3 and Fig. 4 describe the operation principle of the cooling system in detail, and the direction of arrow in Fig. 3 and Fig. 4 is the flowing of air
Direction.
As shown in figure 3, air enters inside kuppe 120 from the air inlet 120a of the front end of kuppe 120, due to arc surface
The presence of the deflector 150 of shape, in air flow to the surface of deflector 150 after, can be spread to surrounding.Sky after the change of direction
Outer surface of the gas along deflector 150 is flowed through around wheel hub entrance 110a, continues to flow backward then along the outer surface of wheel hub 110
It is dynamic.Finally, root or kuppe 120 and the junction discharge kuppe 120 of engine room cover 140 through blade 130.
Due to the presence of deflector 150, when air-flow is blown on the arc surface of deflector 150, flow velocity increase, exerted according to uncle
Sharp equation, gas or liquid flowing its higher pressure of speed per hour degree are smaller, and therefore, air-flow can form low around wheel hub entrance 110a
Nip (the part A region in Fig. 3).Comparatively speaking, the pressure of the air in wheel hub 110 is higher, and air can flow from high-pressure area
To area of low pressure, therefore the high temperature air in wheel hub 110 can be flowed at wheel hub entrance 110a, so as to from kuppe 120
The air that air inlet 120a is blown into flows out together, and then the high temperature air in wheel hub 110 can be discharged into wheel hub 110.When from air intake
The air and the high temperature air of discharge continues to cabin side after the first air outlet 120b is flowed through out of wheel hub 110 that mouth 120a enters
To during flowing, can also be flowed out by the second air outlet 120c.As air by air inlet 120a constantly flows into kuppe 120 simultaneously
Flowed out by the first air outlet 120b and the second air outlet 120c, it is sustainable and effectively take away the high-temperature gas in wheel hub 110,
And then reduce the temperature in wheel hub 110 with pitch control cabinet.
According to exemplary embodiment of the present utility model, because deflector 150 is circular arc face structure, it is possible to taking turns
Hub entrance 110a surrounding (in 360 degree) forms low-pressure area, aspirates and takes away the high-temperature gas in wheel hub 110, it is possible to real
Now more preferable radiating effect；Meanwhile the cooling system will not be influenceed by wind generating set yaw and wind direction, even if wind direction is not
It is face kuppe front end, can also realizes above-mentioned radiating effect.
In addition, as shown in figure 4, for the wind power generating set with external gear electric variable propeller system, pitch drive motor
190 are generally arranged at the outside of wheel hub 110, therefore while being radiated to wheel hub 110, can also be to pitch drive motor
190 carry out complementary radiating.
