Abstract

A heat dissipating apparatus has a micro-structure layer. Two highly heat conductive members are provided, each having structured patterns. A highly heat conductive material is coated on the structured patterns by injection molding for forming a micro-structure layer. The two highly heat conductive members are assembled to form a heat dissipating apparatus having a micro-structure layer. The heat dissipating apparatus includes a main body composed of the highly heat conductive members. The main body forms an accommodating cavity, and inner surfaces of the accommodating cavity form the micro-structure layer. A working fluid is filled into the accommodating cavity for transferring heat from a heat absorbing surface to a heat dissipating surface.
