Kühlgebläse, das keine elektromagnetischen Störungen erzeugt |
摘要 |
A non-electromagnetic interference generating cooling fan includes a case, an impeller pivotally fitted within the case and formed with a cylindrical recess, a magnetic conductive sleeve fixedly arranged within the cylindrical recess thereby enclosing a bottom and vertical surface of the cylindrical recess, an annular ring-like rotor made of permanent magnet fixedly fitted within the sleeve, a stator fitted within the rotor, and a multi-layer printed circuit board fixedly mounted on a top of the stator and within the case, whereby the rotor and stator are enclosed within a magnetic conductive device so as to prevent the magnetic lines of force from getting out of the fan thereby keeping a computer from electromagnetic interference. |
