Engine room casing of wind power generator

Abstract

The invention creatively provides an engine room casing of a wind power generator. The engine room casing comprises an engine room casing body and a heat dissipation device, wherein the heat dissipation device comprises a ventilation pipe, a ventilation pipe sleeve, an outer connecting part, an inner connecting part, an air inlet barrel and an air dissipation barrel; the ventilation pipe sleeves and penetrates into the tail part of the engine room casing body; the ventilation pipe sleeve sleeves the ventilation pipe; the ventilation pipe can rotate relatively to the ventilation pipe sleeve; the outer connecting part is arranged at one end, which extends to the outer part of the engine room casing body, of the ventilation pipe; the inner connecting part is arranged at one end, which extendsinto the engine room casing body, of the ventilation pipe; the air inlet barrel and the air dissipation barrel are tightly screwed on the outer connecting part and the inner connecting part respectively through threads; a blade for collecting air flow is arranged at an air inlet of the air inlet barrel; a plurality of heat dissipation holes are formed in the surface of the outer connecting part;the inner connecting part is provided with a wide-opening type hot air outlet. According to the engine room casing of the wind power generator, provided by the invention, a very good heat dissipationeffect is realized on the basis of keeping layout and shape of each part of the engine room casing; the engine room casing is low in cost, simple in structure and strong in practicability.

Description

technical field [0001] The invention belongs to the technical field of wind power generators, and in particular relates to a nacelle cover of a wind power generator. Background technique [0002] The wind turbine needs to use the nacelle cover when it is in use, and the nacelle cover protects the generator, but the wind generator will generate a lot of heat when it is in use. If the heat cannot be dissipated in time, it will affect the normal operation of the generator, and even There are hidden dangers in production safety, which is not conducive to production. For example, the doubly-fed wind turbines that are currently in operation, because the nacelle cover contains long-term operating mechanical components such as the main shaft, gearbox, and generator, the temperature inside the cover is relatively high, posing a safety hazard. Therefore, in many high-heat areas, there is an urgent need to improve the heat dissipation inside the nacelle cover and its own heat insulati...
