Radiator fan module

Abstract

A radiator fan module has a fan assembly, cooling fin and heat conductor. The fan assembly has a shell seat and fan blade, an air outlet is set at one side of the shell seat, the cooling fin is set correspondingly to the outlet, and the cooling end of the conductor is mated with the fin. The outlet forms an inward extended wall, an outward extended wall and an extended inner space set between the outlet and fan blade. The outlet has a width-reducing pattern. A notched space is formed externally between the inward extended wall and shell seat. An inward extended heat conductor is formed by the extension of the inner end of the cooling fin and is located within the range of the extended inner space, and provided with a blade corresponding side that is located correspondingly to a peripheral position of the blade.

1 . A radiator fan module, comprising: a fan assembly, a cooling fin and a heat conductor; the fan assembly comprises of a shell seat and fan blade pivoted into the shell seat; an air inlet is set onto at least one surface of the shell seat, and an air outlet at one side; the cooling fin is set correspondingly to the air outlet; the cooling end of the heat conductor is mated with the cooling fin, while the heated end of the heat conductor is extended outwards, of which:
 the air outlet is protruded to form an inward extended wall, an outward extended wall and an extended inner space set between the air outlet and fan blade;   the air outlet has a width-reducing pattern, such that the inward extended wall is located nearby the corresponding center of the fan blade;   a notched space is formed externally between the inward extended wall and shell seat;   an inward extended heat conductor is formed by the extension of the inner end of the cooling fin; the inward extended heat conductor is located within the range of the extended inner space, and provided with a fan blade corresponding side that is located correspondingly to a peripheral position of the fan blade.   
     
     
         2 . The structure defined in  claim 1 , wherein said cooling fin is made of multiple heat-conducting fins arranged vertically or horizontally. 
     
     
         3 . The structure defined in  claim 1 , wherein said heat conductor is either a heat pipe or hot plate. 
     
     
         4 . The structure defined in  claim 1 , wherein the cooling end of said heat conductor can be mated with either side of the cooling fin. 
     
     
         5 . The structure defined in  claim 1 , wherein the fan blade corresponding side of the inward extended heat conductor is available with either of curved, stepped or corrugated surface. 
     
     
         6 . The structure defined in  claim 1 , wherein said heat conductor is a flat heat pipe; an opening is set onto the outward extended wall of the air outlet for exposing one side of the cooling fin; the cooling end of the heat conductor with a pattern of flat heat pipe is set into a vertical surface for abutting onto the exposing side of the cooling fin, whilst the heated end of the heat conductor is set into a horizontal surface by turning around 90°. 
     
     
         7 . The structure defined in  claim 1 , wherein an inward bulging margin is set at the mating point of the inward extended wall and the shell seat. 
     
     
         8 . The structure defined in  claim 1 , wherein one side of the cooling fin includes a vertical wall flange; a notched portion is set at one side of the air outlet for exposing of the vertical wall flange of the cooling fin; and a heat-conducting block is set on the external surface of the vertical wall flange; the heat-conducting block contains a mating surface and an insertion slot; the mating surface is incorporated onto external surface of the vertical wall flange of the cooling fin, and the insertion slot is used for inserting the cooling end of the heat conductor.
