风力发电机组变流器IGBT模块散热方式研究

Study on heat dissipation mode of IGBT module for wind turbine generator converter

对现阶段用于风力发电机组变流器IGBT模块散热的空气冷却、液体冷却、热管散热和微通道散热技术进行了介绍,重点讨论了这四种散热方式的发展现状以及比较了各自的优缺点,最后对液冷装置进一步的研究方向进行了展望。所得到的结论是:高效冷却介质和结构优化后的水冷板结合的液冷方式是未来最具潜力的研究方向。

Several kinds of air cooling, liquid cooling, heat pipe heat dissipation and micro-channel heat dissipation technologies were introduced used for the current wind turbine converter IGBT module, the development statuses of these four heat dissipation methods were mainly discussed, advantages and shortcomings of those methods were compared. Finally, the further research directions of liquid cooling devices were prospected. The conclusion is that the liquid cooling method combining high-efficiency cooling medium and water-cooled plate with optimized structure is the most potential direction in the future.
