PURPOSE: An aerogenerator is provided to cool a nacelle section with natural convection circulation of air according to the differences in atmospheric pressures between an air inlet and outlet unit. CONSTITUTION: An aerogenerator comprises a nacelle cover(130) and a nacelle cooling unit. The nacelle cover generates power through a rotary motion of a blade(103) rotated by wind and includes a nacelle generating electric power. A tower(101) includes a plurality of cables connected to the nacelle and supports the axial weight of the nacelle cover by connecting the nacelle cover in an upper end. The nacelle cooling unit comprises an air inlet unit(141) located in a lower part of the tower and an air outlet unit located in one side of the nacelle cover. The nacelle cooling unit cools a nacelle section with natural convection circulation of air according to the differences in atmospheric pressures between the air inlet and outlet unit. |
