Specific embodiment
Below in conjunction with Figure of description and specific embodiment, invention is further described in detail.
Fig. 1 is to Fig. 2 shows a kind of embodiment of the invention, the Wind turbines high-efficiency cooling tower cylinder of the present embodiment, including
Cylinder 1,1 lower part of cylinder are equipped with the column foot layer 4 for installing air-cooled electric component 3, and 1 side wall of cylinder is equipped with for air inlet
Tower door 2 is equipped in cylinder 1 for by 3 air inlet of air-cooled electric component in the air delivery at tower door 2 to column foot layer 4
Air-supply assembly 5.
Air-supply assembly 5 is arranged in the Wind turbines high-efficiency cooling tower cylinder of the present embodiment in cylinder 1, and structure is simple, is transformed into
This is low；The Cryogenic air at tower door 2 is quickly delivered to 5 air inlet of air-cooled electric component using air-supply assembly 5, thus
Greatly reduce temperature rise of the cooling air in cylinder 1, so that the inlet air temperature of air-cooled electric component 5 is nearly close to cylinder 1
External environment temperature, since the inlet air temperature of air-cooled electric component 5 is greatly diminished, (by taking current transformer as an example, actual measurement is close
10 DEG C), so that the ventilating and cooling amount of air-cooled electric component 5 can be improved, guarantee that unit operates normally for a long time.
As further preferred technical solution, in the present embodiment, air-supply assembly 5 includes breeze fan 51, is set to air-supply
