Rotary structure of a heat dissipating fan

Abstract

The invention discloses a rotary structure of a heat dissipating fan capable of maintaining the operation of an axle of the heat dissipating fan along a single axial line by means of a base of the heat dissipating fan and two fixing members disposed at two contact ends of the axle of the heat dissipating fan, so that the axle will not be deviated or collided to produce abnormal noises when the heat dissipating fan is operated.

1 . A rotary structure of a heat dissipating fan, comprising: 
 a heat dissipating fan, comprising a main body and a plurality of vanes radially extended from said main body, and said main body including an axle having a contact end separately disposed on both sides of said main body; and    a base, having a rotary space for accommodating said heat dissipating fan, and said rotary space installing a driving mechanism for driving said heat dissipating fan to rotate, and said base comprising two fixing members disposed at two contact ends corresponding to said axle for maintaining the rotation of said axle along a single axial line.    
   
   
       2 . The rotary structure of a heat dissipating fan of  claim 1 , wherein said fixing member comprises two fixing frames coupled with said base and a bearing disposed on said fixing frame and coupled to said contact end.  
   
   
       3 . The rotary structure of a heat dissipating fan of  claim 2 , wherein said fixing frame is integrally coupled to said base.  
   
   
       4 . The rotary structure of a heat dissipating fan of  claim 3 , wherein said base comprises a disposing member and a lid, and said fixing frame is respectively and integrally coupled with said disposing member and said lid.  
   
   
       5 . The rotary structure of a heat dissipating fan of  claim 2 , wherein said base comprises a fixing section for coupling to said fixing frame.  
   
   
       6 . The rotary structure of a heat dissipating fan of  claim 2 , wherein said contact end has an external diameter smaller than the external diameter of said axle, and said bearing includes a rotary groove having an external diameter equal to the external diameter of said contact end.  
   
   
       7 . The rotary structure of a heat dissipating fan of  claim 6 , wherein said contact end is tapered from the external diameter of said axle.  
   
   
       8 . The rotary structure of a heat dissipating fan of  claim 1 , wherein said contact end has an external diameter smaller than the external diameter of said axle.  
   
   
       9 . The rotary structure of a heat dissipating fan of  claim 8 , wherein said contact end is tapered from the external diameter of said axle.  
   
   
       10 . The rotary structure of a heat dissipating fan of  claim 1 , wherein said contact end is sunk from an end of said axle, and said bearing includes a braking section extended towards said contact end.  
   
   
       11 . The rotary structure of a heat dissipating fan of  claim 10 , wherein said braking section and said contact end have an identical shape.
