Heat pipe and wick structure thereof

Abstract

A heat pipe includes a main body, a wick structure, and a working fluid. The wick structure is formed on an inner wall of the main body and the working fluid is filled in the main body. The coil-shaped wire is attached to the inner wall of the main body so as to form a plurality of grooves. The coil-shaped wire is obtained by winding a copper wire around a supporting frame which has a predetermined shape corresponding to the main body. The supporting frame can be exactly accommodated within the heat pipe.
