Abstract

The invention discloses an offshore wind generating set cooling system adopting a heat pipe for cooling, and relates to the technical field of offshore wind generators. The problems that according to an existing high-power wind driven generator, the temperature of a cabin is likely to rise, a permanent magnet of a fan is demagnetized, and the service life and power generation time of the generator are shortened are solved. A cooling system of a barrel cabin is integrally designed, and a heat pipe type radiator is adopted for cooling for a high-power wind generating set with the power being 10 MW or above. An independent first cooling loop is formed by a direct-drive permanent magnet generator stator, a generator cooling liquid pump, a cooling liquid storage tank, a heat pipe type radiator and a connecting pipe. The control cabinet cooling liquid pump, the control cabinet heat exchanger, the control cabinet, the cooling liquid storage tank, the heat pipe type radiator and the connecting pipe form another independent second cooling loop, and finally heat is cooled in a centralized mode through the heat pipe type radiator. The system is used for carrying out centralized cooling on the direct-driven permanent magnet generator and the control cabinet of the offshore wind generating set.

Description

technical field [0001] The invention relates to the technical field of offshore wind power generators, in particular to a cooling system for offshore wind power generators that adopts heat pipe cooling. Background technique [0002] With the decrease of fossil energy, wind energy, as a conversion form of solar energy, has been paid more and more attention by people. However, in some areas of China, due to geographical location and electrical limitations of wind power generation, and the power system near wind farms is too weak to maintain the power fluctuations caused by wind power generation, it is impossible to introduce a large amount of land wind power. In order to solve the power demand in difficult areas, offshore wind farms have begun to be researched and developed. Since the monsoon is active throughout the year in our country, offshore wind energy resources are very rich, and the annual average wind speed in offshore waters is basically maintained between 7.0 and 8...
