Abstract
The utility model discloses a conductor rotor and a radiating element thereof. The conductor rotor comprises a conducting ring and the radiating element. The radiating element comprises a metal disc. One surface of the metal disc is uniformly provided with a plurality of detachable radiating modules along the periphery of the metal disc. The other surface of the medal disc is connected with the conducting ring. The surface of each radiating module comprises a plurality of parabolic radiating fins which extend towards the outer periphery from the center of the metal disc. Cooling channels are formed between the radiating fins. In the embodiment of the utility model, the surfaces of the radiating modules are provided with a plurality of radiating fins, so that the radiating area is increased; the resistances of the parabolic radiating fins which extend towards the outer periphery from the center of the metal disc to air flow in the rotating process of the conducting rotor are low; meanwhile, when the conducting rotor rotates, approach flow flows along the tangential line of the metal disc and can just successfully enter the cooling channels, so that the best cooling effect on the radiating fins can be achieved under the condition of the lowest resistance.
