Cooler device

Abstract

A cooler device includes a base panel, which has multiple mounting grooves on the top wall and multiple locating grooves on the bottom wall, a radiation fin module formed by stacking up multiple radiation fins, each radiation fin having multiple mounting through holes and a root portion that is respectively riveted to the mounting grooves of the base panel, and multiple U-shaped heat pipes, each heat pipe having a first extension arm respectively and tightly fitted into the mounting through holes of the radiation fins and a second extension arm respectively and tightly fitted into the locating groove of the base panel and kept in flush with the bottom wall of the base panel for direct contact with a CPU or the like to transfer heat energy from the CPU or the like to the radiation fins for quick dissipation.

1 . A cooler device, comprising a base panel, a radiation fin module mounted on said base panel, and at least one heat pipe fastened to said base panel and said radiation fin module and adapted for transferring heat energy from an external semiconductor electronic device to said radiation fin module, each said heat pipe being an enclosed metal tube filled with a working fluid, wherein:
 said radiation fin module is formed of a plurality of radiation fins arranged in a stack, each said radiation fin having at least one mounting through hole cut through two opposite sides thereof for receiving said heat pipes in a tight fit manner and a bottom end terminating in a root portion;   said base panel is extruded from a metal material, comprising a plurality of mounting grooves formed on a top wall thereof and respectively forced into engagement with the root portions of said radiation fins of said radiation fin module and at least one locating groove formed on a bottom wall thereof; and   said at least one heat pipe each has a first extension arm respectively inserted through the at least one mounting through hole of each said radiation fin in a tight fit manner and a second extension arm respectively fitted into the at least one locating groove of said base panel, said second extension arm having a flat bottom wall exposed to the outside of said base panel and kept in flush with the bottom wall of said base panel.   
   
   
       2 . The cooler device as claimed in  claim 1 , wherein said base panel comprises a plurality of elongated grooves formed on the top wall thereof and respectively disposed between each two adjacent mounting grooves of said base panel. 
   
   
       3 . The cooler device as claimed in  claim 2 , wherein said elongated grooves have a V-shaped cross section. 
   
   
       4 . The cooler device as claimed in  claim 1 , wherein each said radiation fin comprises a plurality of mounting through holes for the mounting of the first extension arms of multiple heat pipes; said base panel comprises a plurality of locating grooves on the bottom wall thereof for the mounting of the second extension arms of multiple heat pipes; the distance between each two adjacent locating grooves of said base panel is shorter than the distance between each two adjacent mounting through holes of each said radiation fin. 
   
   
       5 . The cooler device as claimed in  claim 1 , wherein the second extension arm of each said heat pipe has a cross section that fits the cross section of each locating groove on the bottom wall of said base panel. 
   
   
       6 . The cooler device as claimed in  claim 1 , wherein the bottom end of each said radiation fin is folded up to form the respective root portion. 
   
   
       7 . The cooler device as claimed in  claim 1 , wherein the bottom end of each said radiation fin is folded up and crimped into an L-shaped configuration to form the respective foot portion. 
   
   
       8 . The cooler device as claimed in  claim 1 , wherein the bottom end of each said radiation fin is folded up and crimped into a triangular configuration to form the respective foot portion. 
   
   
       9 . The cooler device as claimed in  claim 1 , wherein the bottom end of each said radiation fin is folded up and crimped into an inverted T configuration to form the respective foot portion. 
   
   
       10 . The cooler device as claimed in  claim 1 , wherein the bottom end of each said radiation fin is folded up and crimped into a scroll configuration to form the respective foot portion.
