Heat ventilation device

Abstract

A fan device mounted on the top opening of a cylindrical cooler. Fan comprises a ring plate member, a seat, a plurality of blades, and a plurality of ribs interconnected between the ring plate member and the seat. Blades are rotationally mounted on seat. The bottom of fan is abutted on the inner bottom surface of cooler. Wind generated by the activation of blades is directed toward cooler. As such, the heat transferred from a heat source may be effectively radiated to the outside.

What is claimed is:  
     
         1 . A heat ventilation device comprising: 
 a hollow cylindrical cooler including a plurality of fins parallel longitudinally disposed on the outer surface, a plurality of passages each formed between two of the adjacent fins for providing a heat ventilation path from the inside to the outside, and a bar projected on the underside being in contact with a heat source for absorbing heat therefrom; and    a fan mounted in the cooler with the bottom abutted on the bottom surface of the cooler, the fan including a ring plate member, a seat, a plurality of blades rotationally mounted on the seat, and a plurality of ribs interconnected between the ring plate member and the seat,    whereby wind generated by the blades is directed toward the cooler and the fins, thereby radiating heat transferred from the heat source to the outside through the passages and the fins.    
     
     
         2 . The device of  claim 1 , further comprising a plurality of pairs of parallel inserts at the underside of the ring plate member wherein the pair of the inserts are inserted into two of the passages for engaging the ring plate member with the cooler and a threaded hole at the ring plate member between the pair of the inserts for permitting a fastener to drive through the threaded hole to secure to the passage for securing the fan to the cooler.  
     
     
         3 . The device of  claim 2 , further comprising a connecting member coupled between the pair of the inserts and urged against the inner rear sides of two of the fins.  
     
     
         4 . The device of  claim 1 , further comprising a plurality of elongate arcuate ventilation openings equally spaced apart on the ring plate member.  
     
     
         5 . The device of  claim 1 , further comprising a hole on the ring plate member for allowing a power cord to pass through.
