风力发电机组变流器散热改造研究

Research on heat dissipation transformation of wind turbine converter

风电机组用变流器时热损大,水冷型变流器冷却设备置于塔筒外,利用水将运行产生热携带到换热器中,将热量散发到塔筒外。本文就是防止机变流器高温进行散热改造。通过试验方案将空气进行良好的流通,起到通风散热的目的。

The heat loss of converter for wind turbine is large.The cooling equipment of water-cooled converter is placed outside the tower,and the heat generated by operation is carried to the heat exchanger by using water,and the heat is distributed outside the tower.This paper is to prevent the machine converter high temperature heat transfer transformation.Through the test scheme,the air is well circulated to achieve the purpose of ventilation and heat dissipation.
