Radiator with thin fins

Abstract

A radiator with thin fins. The method includes steps of forming a plurality of thin fins and spacers by punching metal sheets of high coefficient of heat transmission into predetermined shapes, spacing said thin fins alternately with said spacers and binding them into an assembly with a plurality of rivets extended through holes separately formed near lower end at predetermined positions, and grinding a bottom of the assembly to remove unevenness thereof. The radiator manufactured in this method may include increased number of fins within a limited area to create largely increased contact surfaces with air and thereby enables quick radiation of heat produced by, for example, chips associated with the radiator. A fan may be mounted to a top of the radiator to enhance the radiating effect.

What is claimed is:  
     
         1 . A radiator with thin fins, comprising a plurality of thin fins, a plurality of spacers, and a plurality of rivets; 
 said thin fins being made of metal sheets having high coefficient of heat transmission and being formed by punching said metal sheets with dies designed for such purpose, said thin fins being flat and straight and having a plurality of first through holes formed near a lower end at predetermined positions;    said spacers being made of metal sheets having high coefficient of heat transmission and being formed by punching said metal sheets with dies designed for such purpose, said spacers being flat and straight and having a plurality of second through holes formed near a lower end at predetermined positions, said spacers being transversely extended long plate and having a height smaller than that of said thin fins and a thickness preferably larger than that of said thin fins;    said thin fins being spaced alternately with said spacers with said first through holes aligned with said second through holes; and    said rivets being extended through said aligned first and second through holes to firmly bind said thin fins and said spacers together; and    said radiator being ground to remove any unevenness at a bottom thereof;    whereby a large number of said thin fins may be included in said radiator to provide largely increased contacting surfaces with air and accordingly ensure quick radiating of heat produced by a working element, such as a chip in a computer, and whereby said radiator may be economically produced to have different dimensions simply by correspondingly increasing numbers of said thin fins and said spacers without the need of cutting more dies.    
     
     
         2 . A radiator with thin fins as claimed in  claim 3 , wherein said metal sheets for forming said thin fins and said spacers may be aluminum or copper that has high coefficient of heat transmission.  
     
     
         3 . A radiator with thin fins as claimed in  claim 3 , wherein two outmost ones of said a plurality of thin fins are provided on a top edge at predetermined positions with outward extended ears to which a radiator fan may be fastened to enable said radiator to provide enhanced radiating effect.
