Problems solved by technology

In addition, the air entering the tower has been heated by the heating equipment and cables inside the tower. When it reaches the top of the tower, the temperature of the air has risen. At this time, the heat-generating components inside the nacelle are cooled by the air after the temperature has risen. , the cooling effect is reduced

Embodiment 1

[0025] figure 1 It is a schematic diagram of the cooling system of the wind power generating set in Embodiment 1 of the present invention. The small arrows in the figure indicate the air flow path.

[0026] refer to figure 1 , the cooling system of the wind power generating set according to the embodiment of the present invention includes an air inlet part 1 , an air outlet part 2 and a fan. Wherein, the air inlet part 1 is arranged on the propeller side of the nacelle 3 (that is, the side close to the pitch system in the nacelle), the air outlet part 2 is arranged on the side wall of the tower 4, and the fan is arranged at the air outlet part 2 .

[0027] The air intake part 1 can be arranged on a component located on the side of the blade, such as the side of the wind deflector 6 . Preferably, the air inlet 1 can be arranged on the hub 5 . Specifically, the hub 5 is a hollow body, and the hub 5 is provided with an oar side maintenance hole and a tower side maintenance ho...

Embodiment 2

[0039] figure 2 It is a schematic diagram of the cooling system of the wind power generating set in the second embodiment of the present invention. The small arrows in the figure indicate the air flow path.

[0040] The main difference between the embodiment of the present invention and the first embodiment is that two axial flow fans 15 are used instead of the centrifugal fan 12 of the first embodiment to provide power for the air flow of the cooling system.

[0041] Specifically, an axial fan 15 is provided at the air outlet 2 , the air inlet of the axial fan 15 communicates with the air outlet 2 , and a protection device is provided at the air outlet of the axial fan 15 .

[0042] The protection device is preferably an insect-proof net cover 13, which is used to prevent birds from entering the wind power generating set through the air outlet of the fan.

[0043] In addition, another axial flow fan 15 is provided at the tower top platform provided on the top of the tower ...

Embodiment 3

[0045] image 3 It is a schematic diagram of the cooling system of the wind power generating set according to the third embodiment of the present invention. The small arrows in the figure indicate the air flow path.

[0046] The main difference between the embodiment of the present invention and the first embodiment is that a centrifugal fan 12 and an axial flow fan 15 are used in series to provide power for the air flow of the cooling system. Specifically, an axial flow fan 15 is arranged at the top platform of the tower, and a centrifugal fan 12 is arranged at the air outlet 2, through which the power of high-altitude air entering and flowing to the bottom of the tower can be enhanced.

[0047] The working principle of the cooling system of the wind power generating set according to the embodiment of the present invention will be introduced in detail below.

[0048] The temperature sensor 14 monitors the air temperature in the inner wall of the generator 7 and the inner wa...

Abstract

The invention provides a cooling system of a wind generator set and the wind generator set. The cooling system comprises an air inlet part, an air outlet part and a fan. The air inlet part is arranged at the impeller side of an engine room. The air outlet part is arranged on the side wall of a tower frame. The fan is arranged in the position of the air outlet part. According to the cooling system of the wind generator set, ventilation and heat dissipation are conducted on the wind generator set by means of high-altitude air with the temperature lower than that of the ground, and the temperature of the high-altitude air is lower than that of the ground air, so that the temperature difference between the outside environment air and heating assemblies inside the wind generator set is increased, high-temperature assemblies at the machine head of the wind generator seat are cooled directly, and the heat dissipation efficiency of the wind generator set is improved.

Description

technical field [0001] The invention relates to a cooling technology, in particular to a cooling system of a wind power generator set and the wind power generator set. Background technique [0002] A wind turbine is a power generation device that relies on capturing wind energy and converting kinetic energy into electrical energy. In modern large-scale wind turbines, as the power generated by a single machine increases, the heat generated by the heat-generating components inside the wind turbine is increasing. In particular, wind turbines installed in long-term high-temperature environments are prone to failure during operation. [0003] The heat-generating component of the wind power generating set is mainly the generator located on the top of the wind power generating set. In the high temperature environment in summer, due to the high ambient temperature and the long-term full power generation of the wind turbine, some components such as the generator will dissipate the ...
