Hot air circulation structure of low-temperature wind power generator set and use method thereof

Abstract

The invention relates to a hot air circulation structure of a low-temperature wind power generator set and a use method thereof. The hot air circulation structure comprises a gear box radiator installed on a gear box and a generator radiator and a hot air circulation fan which are installed on a generator, wherein the input end and the output end of the gear box radiator are respectively connected with a first air inlet and a first air outlet arranged on a cabin cover, through an air path pipeline, to form an independent radiating unit, and the input end and the output end of the generator radiator are respectively connected with a second air inlet and a second air outlet arranged on the cabin cover, through an air path pipeline, to form an independent radiating unit; and a keel in the cabin cover serves as a hollow air return pipeline, the bottom end of the air return pipeline is connected with the input end of the hot air circulation fan arranged on the bottom inside the cabin cover through the air path pipeline, and the output end of the hot air circulation fan supplies heat to components on the bottom inside the cabin cover through the air path pipeline. The hot air circulation structure ensures that the temperature inside the cabin cover is uniform, and various kinds of equipment in the cabin can work reliably at proper temperature.

Description

technical field [0001] The invention relates to a device for maintaining a low-temperature wind power generating set working at a suitable temperature, in particular to a hot air circulation structure of a low-temperature wind power generating set and a use method thereof. Background technique [0002] At present, the thermal insulation measures of the known low-temperature wind turbines are mainly to paste a certain thickness of thermal insulation material on the inner wall of the nacelle cover, place an electric heater on the top or side wall or the lower part of the nacelle cover, and install the gear box and the generator respectively. Gear box radiator and generator radiator. The gearbox radiator and generator radiator suck air into the nacelle cover, and then discharge it directly to the atmosphere outside the nacelle cover to ensure that the temperature of the gearbox and generator is not overheated. In addition, a damper is installed at the exhaust outlet of the gen...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the problems of non-uniform heating in the existing nacelle cover and failure of components located at the bottom of the nacelle cover because they are not heated, the purpose of the present invention is to provide a hot air circulation structure of a low-temperature wind power generating set and its application method
