Technical field
The present invention relates to wind power generating set, specifically a kind of offshore wind turbine cooling system.
Background technique
Along with the progressively increase of wind power generating set single-machine capacity, the operation power of the main heat-dissipating part-generator in cabin also can be promoted accordingly, and generator can distribute amount of heat in running, and this directly causes the heat in cabin greatly to increase.If these heats can not be discharged in time, wind power generating set efficiency is reduced greatly, even finally paralysis.Therefore, how can effectively reduce the heat in wind generating set engine room, reach good cooling effect, become one of key issue that the wind power generating set MANUFACTURER more and more payes attention to.
At present, most of wind power generating set normally adopt the air-air type of cooling to reduce the heat in cabin, namely utilize air directly with the interior parts of wind generating set engine room, to carry out heat exchange, reach cooling effect.This type of cooling is according to the difference of engine room inside parts heat dissipating capacity, is divided into again the cooling and forced air cooling of natural ventilation.Natural ventilation is cooling refers to that the parts that are cooled do not arrange any cooling equipment, is directly exposed in air, by the air natural circulation, the heat that parts distribute is taken away, and this is mainly used in the engine room inside parts that heat dissipating capacity is less.Forced air cooling is by the large generator of heat dissipating capacity, air-cooler being installed, and by air-cooler, generator air and ambient air outside is carried out to heat exchange.
The above-mentioned type of cooling mainly is suitable as the heat reduced in the wind generating set engine room of land, can't be used as offshore wind turbine.This is because the offshore wind turbine long-time running, in the maritime climate environment of high temperature, high humidity, contains high humidity and salinity in air, mechanical parts and electrical equipment are had to high corrosivity.Therefore, the engine room inside of offshore wind turbine and the extraneous sealing state that is in high degree of isolation.The conventional way that reduces offshore wind turbine engine room inside heat is, for the large generator of heat dissipating capacity, the air-cooler of installing on transform generator, the cooling tube of air-cooler is replaced with to erosion-resisting titanium pipe, by the percolation passage of titanium pipe as marine air, because the cost of titanium pipe is higher, this has directly increased the holistic cost of unit, and the afloat long-time running of unit, airborne salt grades Impurity deposition at the titanium tube-surface, has had a strong impact on cooling effect and titanium pipe working life; For other less parts of heat dissipating capacity, by engine room inside, installing an air-conditioner and carry out heat exchange, realize coolingly, because the cost of air-conditioning is also higher, this has further increased again the holistic cost of unit.Form all parts high cost of whole unit, bring unfavorable factor for the competition of finished product unit in market.
In sum, research and develop a kind of offshore wind turbine cooling system that can effectively control cost and have the good heat exchange performance, become the task of top priority of wind power generating set MANUFACTURER.
