摘　　要：海上风电发展前景广阔,开发大容量海上风电机组所面临的主要问题包括如何有效地冷却发电机、齿轮箱及变频器等核心部件。通过分析某MW级海上风电机组冷却系统的散热器空间布置形式、散热通道结构设计以及散热器所配风扇性能,利用CFD软件对散热通道内流场进行了三维数值模拟,结果表明,散热器的布置形式直接影响散热通道的系统阻力,进而影响散热器所配风扇与系统的特性匹配。With broad prospect for the development of offshore wind power, how the key components of generator, gearbox and inverter could be cool effectively is a main problem in the design of high ca- pacity offshore wind turbine. An analysis of the cooler layout, cooling passage structure design and cooling fan performance of some megawatt offshore wind turbine cooling system is described, and 3D numerical simulation of cooling passage flow field is carried out by CFD software, the result is that cool- er layout influences the drag of cooling passage directly, further influences the match of cooling fan and cooling system.
