Abstract

A horizontal cooler module includes a heat sink formed of a stack of radiation fins, a base block tightly fitted into the bottom side of the heat sink, and heat pipes each having a first extension arm respectively tightly inserted through the radiation fins and a second extension arm respectively fitted into the bottom open grooves of the base block with a respective flat wall portion of the second extension arm exposed to the outside of the base block and kept in flush with the bottom wall of the base block for direct contact with an external electronic chip to transfer heat energy from the electronic chip to the heat sink for quick dissipation.

Claims

1. A cooler module, comprising a heat sink formed of a stack of radiation fins, a base block attached to said heat sink, and a plurality of heat pipes filled up with a working fluid and tightly inserted through the radiation fins of said heat sink and closely attached to said base block, wherein:

said base block is a metal block, having a top wall fitting one side of said heat sink, and a plurality of bottom open grooves formed on a bottom wall thereof;

said heat pipes each have a first extension arm respectively fastened to each of the radiation fins of said heat sink and a second extension arm respectively and tightly fitted into said bottom open grooves of said base block, said second extension arm having a flat wall portion exposed to the outside of said base block and kept in flush with a bottom wall of said base block for direct contact with a heat source to transfer heat energy from the heat source to said heat sink for dissipation.

2. The horizontal cooler module as claimed in claim 1, wherein said base block is made out of copper or aluminum.

3. The horizontal cooler module as claimed in claim 1, wherein said base block comprises a plurality of clamping ribs respectively extending along two opposite sides of each of said bottom open grooves.

4. The horizontal cooler module as claimed in claim 3, wherein said clamping ribs of said base block each have a longitudinal cut, said longitudinal cut having a V-shaped cross section.
