Abstract

The invention discloses a design method for a heat dissipation system of a wind turbine generator set under a severe environment and the heat dissipation system. An outer air duct is added to a heat dissipation system of an original wind turbine generator set through the five steps of constructing the outer air duct of the heat dissipation system, determining the air volume of the outer air duct, determining the air speed of an air inlet of the outer air duct, determining the area of the air inlet of the outer air duct and forming the air inlet. The air speed of the air inlet is made to be 3 m/s-4 m/s by controlling the area of the air inlet, so that little or no suspended matter is sucked into the outer air duct. Radiators of the original heat dissipation system suck cold air through the outer air duct, and therefore exhaust inlets of the radiators cannot be blocked, the cold air intake volume and the heat dissipation effect are guaranteed, and the wind turbine generator set can meet use requirements under the severe environment.

Description

technical field [0001] The invention relates to the field of wind power generation, in particular to a design method and the heat dissipation system of a wind power generating set heat dissipation system in harsh environments. Background technique [0002] The "Thirteenth Five-Year Plan" in various fields of new energy is being compiled, and wind power will gradually change its current status as an "alternative energy" widely regarded as an "alternative energy source" and rise to become the main body of the country's energy structure adjustment in the future. According to the planning idea, during the "Thirteenth Five-Year Plan" period, the newly installed capacity of domestic wind power will reach 100 million kilowatts, with an average annual increase of 20 million kilowatts. The central and eastern resource areas with medium and low wind speeds will add 30 million kilowatts, and offshore wind power will add 10 million kilowatts. [0003] Regions rich in wind energy resour...
