[0030] In one of the embodiments, according to Figures 1-3 As shown, an efficient radiator includes a heat dissipation member 100 and a fan 200 provided on the heat dissipation member 100; the fan 200 includes a housing 210 and a plurality of blade assemblies 220; the blade assembly 220 includes a plurality of blades 221; a plurality of flow guiding arrays are provided on each blade 221, a rotation cavity 211 is provided inside the housing 210, the blade assembly 220 is rotatably provided in the rotation cavity 211, the heat dissipation member 100 includes a heat conducting core 110 and a plurality of heat dissipation fins 120 provided on the heat conducting core 110; the plurality of heat dissipation fins 120 are uniformly arranged circumferentially around the heat conducting core 110, and a gap 130 is provided between two heat dissipation fins 120, and the gap 130 gradually increases outward from the heat conducting core 110.

[0031] Specifically, by providing the heat dissipation member 100, the heat of the heat source is transferred to the heat dissipation fins 120 through the heat conducting core 110 for heat dissipation. By providing the fan 200 on the heat dissipation member 100, the heat on the heat dissipation fins 120 can be quickly taken away by blowing. At the same time, the flow guiding arrays provided on the blades 221 can change the streamline when the air flows through the blades 221, reduce turbulence and eddy current, improve the smoothness of the air flow, strengthen the blowing force of the fan 200, and increase the heat dissipation efficiency.

A first mounting hole 216 penetrating the rotating frame 213 is provided on each mounting surface 215, and a second mounting hole 142 penetrating is provided on each mounting part 141.

A limit pin 300 passes through the corresponding mounting surface 215 and the mounting portion 141 to detachably connect the heat dissipation member 100 and the rotating frame 213, which belongs to a detachable connection and can be disassembled for cleaning after long-term use.
