Specifically reflected in: Suspended matter (flying catkins, flying dust, coal ash, etc.) will be adsorbed at the air suction port of the radiator. After long-term operation, more and more suspended matter will be adsorbed at the air suction port, which will reduce the cooling air intake of the radiator. , resulting in the failure to achieve the required cooling effect and affecting the normal operation of the generator set

Abstract

The invention discloses a heat dissipation system design method and heat dissipation system of a wind power generating set in a harsh environment. By constructing the external air duct of the heat dissipation system, the air suction volume of the external air duct is determined, the wind speed of the air inlet of the external air duct is determined, and the external air duct is determined. The five steps of the area of ​​the air inlet and the opening of the air inlet have added an external air duct to the heat dissipation system of the original wind turbine, and by controlling the area of ​​the air inlet, the wind speed of the air inlet is 3-4 m / s, so that the outside air can be sucked in. There is little or no suspended matter in the air duct, and each radiator of the original heat dissipation system sucks cold air from the external air duct, so the air suction port of each radiator will not be blocked, which ensures the air intake and heat dissipation effect of the cold air, so that the generator set can Adapt to the needs of harsh environments.

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...
