Background

Wind power generation technology is continuously developed, megawatt wind power is more and more, and the power of a core component converter in a wind turbine generator is also more and more. The high-capacity converter generates a large amount of heat energy in operation, so that the temperature of the converter is continuously increased. If the temperature of the converter cannot be timely dissipated, the converter fails due to overheat and cannot work normally, so that the wind generating set stops working, and economic loss is brought to a wind farm, and therefore, the converter needs to be dissipated.

However, because the space behind the converter in the tower barrel is smaller, heat emitted by the converter can be gathered on the upper part behind the converter, and because of the blocking effect of the two layers of platforms, the heat emitted by the converter cannot be well emitted, so that the local temperature is higher, and the heat-radiating effect of the converter is influenced, and therefore, a novel wind turbine generator tower barrel heat-radiating device needs to be designed.
