Abstract

A heat dissipation structure for heat dissipation device includes a heat dissipation device main body that internally defines a chamber, and the chamber is internally provided with at least a whisker layer and a working fluid. The whisker layer is provided on an inner wall surface of the chamber. By providing the whisker layer in the chamber, it is able to provide largely upgraded capillary effect in the chamber to thereby increase the vapor/liquid cycling efficiency of the working fluid in the heat dissipation device, enabling the latter to have upgraded heat transfer performance.
