Natural air cooling and forced air cooling combined radiator structure

According to the natural air cooling and forced air cooling combined radiator structure, an air radiator is arranged on the windward side of the top of a wind turbine generator, the air radiator structure combining the natural air cooling structure and the forced air cooling structure is adopted, compared with full-natural air cooling, the cooling capacity is increased, and compared with full-forced air cooling, the energy consumption is reduced. The forced air cooling structure is provided with a plurality of fans, so that the maintenance height of the fans is reduced, the fans can be conveniently overhauled and maintained, the space occupied by the internal space of the fan unit is reduced, the electric power consumption of the air radiator is reduced, and resources are saved. 一种自然风冷与强迫风冷组合散热器结构，其空气散热器设置于风电机组顶部的迎风面，采用自然风冷结构与强迫风冷结构组合的空气散热器的结构，与全自然风冷相比增大了冷却容量，与全强迫风冷相比降低了能耗。在所述强迫风冷结构中设有若干风机的结构降低了风机维护高度，有利于检修维护风机，减少了在风机机组内部空间占用的空间大小，降低了空气散热器的电功耗，节约了资源。
