Patent ID: 7578338

Claim:
A heat dissipating apparatus having a micro-structure, comprising: a highly heat conductive member comprised of a highly heat conductive material, and having an accommodating cavity formed therein, wherein an inner wall of the accommodating cavity comprises a structured pattern, said highly heat conductive member further comprising a heat absorbing surface defined on an outer surface thereof, for being in contact with a heat source and absorbing heat generated by the heat source, and a heat dissipating surface defined on another outer surface thereof and opposite to the heat absorbing surface, for dissipating the heat to an outside environment; a micro-structure layer formed on the structured pattern, wherein the micro-structure layer is made of the highly heat conductive material; and a working fluid that fills the accommodating cavity, wherein at least a portion of the working fluid at a position close to the heat absorbing surface will absorb the heat from the heat absorbing surface causing the portion of the working fluid to vaporize, and wherein the vaporized working fluid coveys the absorbed heat to a position close to the heat dissipating surface, causing the absorbed heat to be released to the heat dissipating surface, thereby causing the vaporized working fluid to condense, with the condensed portion of the working fluid moving back to the position close to the heat absorbing surface due to gravity and capillary force.
