Example 1

As shown in fig. 1, the present embodiment discloses a fairing, which is installed on a wind turbine generator system, and is used for protecting a hub of the wind turbine generator and simultaneously evenly shunting airflow according to the streamline shape of the fairing.

The fairing of the present embodiment, like a conventional wind turbine fairing, comprises a shroud having a straight portion 1 and a tapered portion 10. In order to improve the heat dissipation effect of the fairing, as shown in fig. 1, the straight portion 1 of the fairing body of the embodiment is provided with an air outlet 9, the tapered portion 10 of the fairing body is provided with an air inlet 3, and the interior of the fairing body is provided with an air inducing component 2, wherein the air inducing component 2 and the air inlet 3 are positioned on the same horizontal plane and used for inducing air coming from the air inlet 3 to the air outlet 9. Like traditional wind generating set, the conical part 10 of the cover body is in windward state when using, and under the effect of wind force, the outside air of radome fairing enters the internal portion of cover from air intake 9, is guided to air outlet 9 by induced air subassembly 2 with the air that gets into, and is discharged outside the cover body by air outlet 9 again.

In order to take away hot air in the cover body, a distance is formed between the air inlet end of the air inducing component 2 and the air inlet 3, and the hot air in the cover body can be taken away in the process that external air enters from the air inlet 3 and is discharged through the air inducing component 2 and the air outlet 9. If the distance is too large, the air entering from the outside cannot be well gathered to the air inducing assembly 2; if the distance is too small, the hot air in the housing is not well taken into the air inducing assembly 2. In this embodiment, the distance is set to 1/5 of the length of the cover, which ensures that both the air coming from the outside and the hot air in the cover can enter the induced draft assembly 2.

The air inlet 3 and the air outlet 9 in the embodiment are positioned at the upper half part of the cover body, and hot air floats upwards, so that the hot air is easier to discharge.

In addition, the tapered portion 10 is provided with an air inlet rain shield 5, and the straight portion 1 is provided with an air outlet rain shield 8. The air inlet rain shield 5 extends towards one side of the tip end of the conical part 10 and is used for shielding the air inlet 3 from the upper part; in addition, the opening of the air inlet rain shield 5 faces the windward end of the conical part 10, so that air enters the air inlet rain shield 5 from the opening thereof and enters the cover body from the air inlet 3, and rainwater flows downwards along the inclined plane of the conical part 10 and flows to the ground after turning over the air inlet rain shield 5, thereby preventing rainwater from entering the cover body from the air inlet 3.

As shown in fig. 2, the outlet rain shield 8 is used for shielding the outlet 9 from above, and the opening direction of the outlet rain shield 8 is opposite to the opening direction of the inlet rain shield 5, that is, the opening direction of the outlet rain shield 8 is in the downwind direction, which is more beneficial to the discharge of air. In addition, an air outlet channel 7 is formed between the air outlet rain shield 8 and the outer surface of the straight portion 1, and the air outlet channel 7 is communicated with the induced draft cover 22 through the air outlet 9. The air entering the cover body passes through the induced air assembly 2, the air outlet 9 and the air outlet channel 7 in sequence and then is discharged out of the cover body.

This air outlet rain shade 8 can prevent that the rainwater from entering into air outlet 9 from the top, and sets up air outlet 9 on straight portion 1, and the rainwater on straight portion 1 can follow the cover body both sides downward flow and can not follow straight portion 1 horizontal flow, has reduced the rainwater and has entered into the probability of covering the internal from air outlet 9.

As shown in fig. 3, the induced draft assembly 2 includes an induced draft cover 22 connected to a wind collecting cover 21, the wind collecting cover 21 communicates with the induced draft cover 22, and the induced draft cover 22 communicates with the air outlet 9. The wind gathering cover 21 is trumpet-shaped, so that air can be gathered conveniently. The position and size of the wind inducing assembly 2 are set according to circumstances as long as the installation of parts such as a hub of the wind power generator is not affected.

When the air-cooling hood is used, the conical part 10 of the hood body is in a windward state, external air is blown into the hood body from the air inlet 3, the air is collected by the wind-gathering hood 21 when flowing along the hood body, then the air is discharged out of the hood body along the wind-gathering hood 21, the wind-guiding hood 22 and the air outlet channel 7, hot air in the hood body is brought into the wind-gathering hood 21 and is discharged out of the hood body along with the wind-gathering hood 21, and therefore the temperature in the hood body is reduced.

Example 2

In this embodiment, on the basis of embodiment 1, the filter screen 4 is disposed on the air inlet 3, and the filter screen 4 can prevent external foreign matters from entering the cover body from the air inlet 3. Of course, a filter screen may also be disposed on the air outlet 9.

Example 3

As shown in fig. 2, the outer surface of the straight portion 1 is provided with a weather shield 6; the rain baffle 6 is positioned in the air outlet channel 7 and is close to one side of the opening of the air outlet rain shield 8. The rain shield 6 can prevent rainwater from flowing horizontally along the outer surface of the cover body and entering the cover body from the air outlet 9.

Specifically, a gap is formed between the upper end of the rain shield 6 and the inner surface of the rain shield 8 at the air outlet, and the upper end of the rain shield 6 is inclined towards the side far away from the air outlet 9, so that air can smoothly flow out of the air outlet channel 7.

It should be noted that all of the features disclosed in this specification, or all of the steps in any method or process so disclosed, may be combined in any combination, except for mutually exclusive features and/or steps.

In addition, the above embodiments are exemplary, and those skilled in the art can devise various solutions in light of the disclosure, which are also within the scope of the disclosure and the protection scope of the present invention. It should be understood by those skilled in the art that the present specification and its drawings are illustrative and not restrictive on the claims. The scope of the invention is defined by the claims and their equivalents.
