Abstract
A fan with electromagnetic radiation shielding structure includes a fan impeller and a shaft seat. The fan impeller includes a metal hub, a plurality of blades circumferentially spaced on an outer surface of the metal hub, and a magnetic element provided on an inner surface of the metal hub. The shaft seat is provided at a central area with an upward projected shaft barrel, which is rotatably connected to the fan impeller and has a stator externally fitted therearound. A metal carrier is provided on the shaft seat and has a peripheral edge extended upward to form a sidewall and define an open-topped receiving space for receiving the stator therein. The metal hub and the metal carrier together define a shielding space, such that the stator is located in the shielding space and isolated from outer environment to avoid leakage of electromagnetic radiation produced by the stator.
