Cooling fan providing enhanced heat dissipating effect

Abstract

A cooling fan includes a radiator having a plurality of radiation fins, and a fan connected to a top of the radiator. The fan includes a frame and a plurality of blades mounted in the frame at an inclined position relative to the top of the radiator. Therefore, airflows produced by the blades of the fan are directly continuously blown toward side surfaces of the radiation fins of the radiator to accelerate the dissipation of heat transferred from an operating electronic element to the radiation fins.

1 . A cooling fan providing enhanced heat dissipating effect, comprising: 
 a radiator having a plurality of radiation fins; and    a fan connected to a top of said radiator and including a frame and a plurality of blades mounted in said frame; said frame having a triangular cross section, so that said blades are mounted in said frame at an inclined position relative to the top of said radiator;    whereby when said fan operates, airflows produced by said fan are kept blown toward side surfaces of said a plurality of radiation fins to more quickly carry away heat transferred to said radiation fins.    
   
   
       2 . The cooling fan as claimed in  claim 1 , wherein said fan is connected to the top of said radiator by means of fastening elements.  
   
   
       3 . The cooling fan as claimed in  claim 1 , wherein said frame of said fan is provided at outer sides of two lower ends with two slide ways, and said radiator is provided at upper ends of two outmost ones of said radiation fins with two inward projected rails corresponding to said slide ways on said frame, so that said fan is connected to the top of said radiator through engagement of said slide ways with said rails.  
   
   
       4 . A cooling fan providing enhanced heat dissipating effect, comprising: 
 a radiator having a plurality of radiation fins; and    a fan connected to a top of said radiator and including a frame and a plurality of blades mounted in said frame; and said blades being mounted in said frame at an inclined position relative to the top of said radiator;    whereby when said fan operates, airflows produced by said fan are kept blown toward side surfaces of said a plurality of radiation fins to more quickly carry away heat transferred to said radiation fins.    
   
   
       5 . The cooling fan as claimed in  claim 4 , wherein said fan is connected to the top of said radiator by means of fastening elements.
