Abstract

A cooling module is disclosed which comprises a plate, a flat heat pipe, a directional motor, and a fin structure, wherein at least a part of the heat pipe is embedded into the plate while being flush with plate, and the heat pipe is disposed close to a heat generating object and a coupling portion of the fin structure.

Claims

1. A cooling module comprising:

a collector for receiving heat from a heat generating object, a fan motor capable of causing a directional air flow, and blades and a fin structure which are disposed on a plate,

an air guide disposed surrounding at least said fan motor and said blades on said plate, and

a cover applied to said air guide so as to form a duct,

a heat pipe and a groove for receiving said heat pipe provided on and in the lower surface of said plate, while making a detour around a position used for mounting said motor fan, said heat pipe and said groove ranging from said collector to said duct, and

a cover made of good heat conduction applied to the upper side of said fin structure.
