Heat dissipation device for wind power generator

Abstract

The invention discloses a heat dissipation device for a wind power generator. An air guide box body is arranged outside the wind power generator, a heat dissipation box body communicated with the air guide box body is arranged at the tail end of the air guide box body, the air guide box body is provided with ventilation holes, a heat dissipation fan is arranged on the inner wall of the tail end of the heat dissipation box body, and a cover body is arranged outside the heat dissipation fan. An air outlet facing the wind power generator is formed in the cover body. A refrigeration box is further arranged in the heat dissipation box body, refrigeration equipment used for generating cold air is arranged in the refrigeration box, the refrigeration box is provided with an air inlet pipe and an air outlet pipe, the air inlet pipe extends into the air outlet, and the air outlet pipe extends to the wind power generator. The air inlet pipe forms a first air outlet channel, a second air outlet channel is formed between the outer surface of the air inlet pipe and the inner wall of the air outlet, a driving assembly and an air baffle are arranged on the cover body, and the driving assembly is connected with the air baffle and used for driving the air baffle to open or close the first air outlet channel and the second air outlet channel. By adopting the heat dissipation device for the wind power generator, the wind power generator can be quickly cooled in an energy-saving manner.

Description

technical field [0001] The invention belongs to the field of electric equipment, in particular to a cooling device for wind power generators. Background technique [0002] Wind power generation refers to the conversion of wind kinetic energy into electrical energy. Wind energy is a clean and pollution-free renewable energy source. The use of wind power generation is very environmentally friendly, and the wind energy reserves are huge, so it is increasingly valued by countries around the world. For water shortages, Coastal islands, grassland pastoral areas, mountainous and plateau areas that lack fuel and have inconvenient transportation are very suitable and promising to use wind power according to local conditions. [0003] Existing wind power generation equipment mainly includes a tower, a nacelle installed on the top of the tower, a wind generator installed in the nacelle, a speed-regulating gearbox, a hub and other important equipment, as well as wind turbine blades conn...
