Radiating air fan

Abstract

The present invention provides an improvement for radiating air fan, mainly improvements are: Eliminated the plastic outer frame in the conventional one and replaced the radiator as utilization as the said outer frame in this improved design which unitizing the radiator and the outer frame as a configurable embodiment. Additionally, the central pillar base and the radiator are separated for the central pillar base can be inlayed into the radiator for riveted jointing without other bolted or riveted jointing elements, which can conform a fast assembling combination more efficiently. Furthermore, this design, also, can enforce the effect of heat radiating and can save the cost of assembling and time.

WHAT IS CLAIMED IS  
     
         1 . An improvement for radiating air fan, mainly complies: 
 A structure of outer frame,    a radiator,    an air fan and    a set of; wherein 
 of its characteristics as to eliminate the plastic outer frame used in the conventional radiating air fan, and directly utilizing the radiator as an outer frame for its configurationally structural design as a unitized one, where securely jointing the central pillar base and the radiator without any rived joint element.  
   
     
     
         2 . The fan according  claim 1  wherein by eliminating the plastic outer frame structure and replaced and utilizing the radiator as an outer frame for the radiator and the outer frame been deigned as a unitized configuration as a whole, of which is made of aluminum alloy.  
     
     
         3 . The fan according  claim 1  wherein the central pillar base and radiator jointed by external forces and by the positioned convex tip to correspond with the riveted joint section as well as directly been secure jointed at the riveted joint section without any element of bolted/riveted joint.  
     
     
         4 . The fan according  claim 2  wherein by eliminating the plastic outer frame structure and replaced and utilizing the radiator as an outer frame for the radiator and the outer frame been deigned as a unitized configuration as a whole, where total radiating area can widen on the radiator and, also, the height of the blade can be heighten efficiently under the same volume for accessing more convectively air flowing capacities under the same R.P.M, of the said two matters can available for heat radiating effect.  
     
     
         5 . The fan according  claim 3  wherein designed the combinational jointed elements for the air fan, central pillar base and radiator to be been as an assembling set in the conventional air fan, of its defects, more jointing elements, more time and labor consuming; for this design for utilizing the external forces to joint the said jointed procedures which can huge improve the assemble efficiently and can save the cost.
