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 or by means of closed-end heat tubes, 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, which is a solid cylinder having a top side, a bottom side and a lateral periphery between the top side and the bottom side, and   a plurality of metal radiation fins mounted on the lateral periphery of said metal base member, wherein   said metal radiation fins each have an outer side, at least one hooked portion respectively extending from the outer side, an inner side, and at least one backwardly curved and crimped bottom mounting portion respectively extending from the inner 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 the lateral periphery, extending along a length of the lateral periphery in parallel with one another and spaced around the lateral periphery, said deep locating grooves respectively receiving 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 lateral periphery 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 , further comprising a metal bottom panel formed integral with the bottom side of said base member.
