Cooler device

Abstract

A cooler device includes a metal base member and a plurality of metal radiation fins. The metal base member has parallel locating grooves; the metal radiation fins are fastened to one another in a stack by respective hooked portions thereof, the metal radiation fins each having backwardly curved and crimped bottom mounting portions respectively fitted into the locating grooves of the metal base and fixedly secured thereto by means of compacting the locating grooves of the metal base member without electroplating or using solder paste or bonding means.

1 . A cooler device comprising a metal base member, and a plurality of metal radiation fins mounted on said metal base member, wherein
 said metal radiation fins each have a top side, at least one hooked portion respectively extending from the top side, a bottom side, and at least one backwardly curved and crimped bottom mounting portion respectively extending from the bottom side, the at least one hooked portion of one of said metal radiation fins being fastened to the at least one hooked portion of another one of said metal radiation fins;   said metal base member has a plurality of deep locating grooves formed on a surface thereof that receive the backwardly curved and crimped bottom mounting portions of said radiation fins; and   said metal base member is compressed to fixedly secure the backwardly curved and crimped bottom mounting portions of said radiation fins to said metal base member.   
   
   
       2 . The cooler device as claimed in  claim 1 , wherein said base member has a plurality of shadow grooves formed on the top wall thereof in parallel to said deep locating grooves and respectively spaced between each two adjacent deep locating grooves. 
   
   
       3 . The cooler device as claimed in  claim 1 , wherein the backwardly curved and crimped bottom mounting portions of said metal radiation fins show a U-shaped profile. 
   
   
       4 . The cooler device as claimed in  claim 1 , wherein the backwardly curved and crimped bottom mounting portions of said metal radiation fins show an L-shaped profile. 
   
   
       5 . The cooler device as claimed in  claim 1 , wherein the backwardly curved and crimped bottom mounting portions of said metal radiation fins show a triangular profile. 
   
   
       6 . The cooler device as claimed in  claim 1 , wherein the backwardly curved and crimped bottom mounting portions of said metal radiation fins show an inverted T-shaped profile. 
   
   
       7 . The cooler device as claimed in  claim 1 , wherein the backwardly curved and crimped bottom mounting portions of said metal radiation fins show a scroll-shaped profile. 
   
   
       8 . The cooler device as claimed in  claim 1 , wherein said metal base member is a flat solid rectangular metal panel.
