A heat dissipation system for a permanent magnet direct drive crane comprises a water-cooling permanent magnet direct drive winding drum and a heat exchange device. The heat exchange device comprises an air duct, a plurality of horn-shaped air guide covers are arranged in the air duct at intervals in the axial direction, the large-diameter ends of the air guide covers are connected with the inner wall of the air duct in a fastened mode, and the diameter of the large-diameter ends of the air guide covers is smaller than the inner diameter of the air duct. The small-diameter end of one of two adjacent wind scoopers is inserted into the large-diameter end of the adjacent wind scooper; annular heat exchange rows capable of circulating cooling media are arranged at the large-diameter end of the wind scooper, every two adjacent annular heat exchange rows are communicated in series, and a cooling pipeline of the water-cooling permanent magnet direct drive winding drum is correspondingly communicated with the annular heat exchange rows through a circulating pump. A cooling fan is arranged in the small-diameter end of the wind scooper; the cooling tower is compact in structure, good in cooling effect and ingenious and reasonable in layout, and compared with a traditional cooling tower, the size can be greatly reduced.

    一种永磁直驱起重机用散热系统,包含水冷永磁直驱卷筒和换热装置;所述换热装置包含风筒,风筒内沿轴向间隔设有多呈喇叭状的导风罩,导风罩大径端与风筒内壁紧固连接,且导风罩大径端直径小于风筒的内径;相邻两个导风罩中的其中一个导风罩的小径端头插入相邻导风罩的大径端内;导风罩的大径端设有能够流通冷却介质的环形换热排,且相邻的两个环形换热排串联连通,所述水冷永磁直驱卷筒的冷却管路通过循环泵与环形换热排对应连通;导风罩的小径端内设有散热风扇;本发明结构紧凑,散热效果好,布局巧妙合理,与传统散热塔相比能够极大的缩减体积。
