Oil cooling apparatus for accelerator of wind power generator and wind power generator comprising the same

摘要

PURPOSE: An oil cooling device for a gearbox of an aerogenerator and an aerogenerator applying the same are provided to omit a management work of a dimensional tolerance between bolt holes because the bolt hole fixing an intake duct on an air inlet of a nacelle is removed. CONSTITUTION: An oil cooling device(160) for a gearbox(136) of an aerogenerator(100) comprises a radiator(164), an intake duct(162), a cooling fan(166), an oil pass(170), and a filter(180). The radiator installed inside a nacelle(130) cools the oil for a gearbox by using the external air flowing in via an air inlet unit(135) of the nacelle. The intake duct installed in the lower part of the radiator at the upper part of the air inlet guides the external air to the radiator. The cooling fan discharges the external air heated by heat exchange with the oil for the gearbox to the outside of the nacelle. The oil pass circulates the oil for the gearbox between the gearbox and the radiator. The filter is installed between the air inlet unit of the nacelle and the intake duct. The filter prevents foreign substances coming in through a gap between the intake duct and the air inlet unit of the nacelle.
