Referring to fig. 1, fig. 1 shows a schematic diagram of a wind turbine generator system according to an embodiment of the present application, and a wind turbine generator 100 according to an embodiment of the present application includes a tower 110 and a cooling fan 120. The cooling fan 120 is installed in the tower 110, and the tower 110 is provided with a corresponding cooling hole 112, the cooling fan 120 dissipates heat of the high-power device in the tower 110, and the generated hot air flow (hot air) is output out of the tower 110 through the cooling hole 112, so as to maintain the normal operation of the high-power device in the tower 110 and prevent high-temperature faults.

In the conventional art, a vertical louver is generally provided on the heat dissipation port 112 to shield rain and fog and flying insects, and the heat dissipation is achieved by opening the blades of the louver by hot air flow, however, the vertical louver has several drawbacks: when the heat dissipation port 112 of the tower 110 faces the main wind direction of the external wind, the external wind applies wind pressure to the blades of the louver, so that the louver cannot be opened and the internal hot air cannot be discharged; the blades of the shutter can be closed and opened back and forth under the action of external wind, unidirectional conduction cannot be achieved, and rain and fog easily flows back into the tower 110; the vanes of the blind cannot be completely sealed, and flying insects and small animals can enter the tower 110 through the gaps.

At least a portion of the check valve 150 is disposed in the output end 142, and is configured to unidirectional conduct the output end 142 from inside to outside under the pressure (wind pressure) of the airflow output from the heat dissipation port 112.

By arranging the bent guide pipe 140, the input end 141 and the output end 142 of the guide pipe 140 are not on the same axis, so that the influence of external wind on heat dissipation is reduced or avoided; when the cooling fan 120 is started, under the action of the pressure (wind pressure) of the air flow output by the cooling port 112, the one-way valve 150 is automatically opened to enable the output end 142 to be unidirectionally conducted from inside to outside, and the hot air flows through the output end 142 to be output to the outside, when the cooling fan 120 stops working, the one-way valve 150 is not affected by wind pressure to automatically close the output end 142, so that rain and fog can be prevented from flowing backward, flying insects and small animals can be prevented from entering the tower 110. Therefore, the heat dissipation and guide device 130 avoids the situation that the blades of the traditional shutter cannot be opened under the action of wind pressure exerted by external wind, is slightly influenced by the external wind, and can be conducted in a unidirectional manner to well isolate rain and fog, flying insects and small animals.

In this embodiment, the included angle θ between the central axis L1 of the input section 145 and the central axis L2 of the output end 142 is 90 °, so that the input section 145 is disposed perpendicular to the output section 147. It is understood that in other embodiments, the angle θ between the central axis L1 of the input section 145 and the central axis L2 of the output end 142 may be 80 °, 70 °, 60 °, 50 °, 45 ° or less.
