Abstract

A wick structure is attached on an internal sidewall of a heat pipe. The wick structure includes a plurality of orthogonal woven fibers. The fibers extending along a longitudinal direction of the heat pipe are thinner; therefore the wick structure is capably of providing enhanced capillary action and good attachment to the heat pipe.

Claims (4)

1. A wick structure attached on an internal sidewall of a heat pipe, comprising:

a plurality of longitudinal fibers extending along an axial direction of the heat pipe; and

a plurality of transversal fibers thicker than the longitudinal fibers, orthogonally woven with the longitudinal fibers to form a one-layer wick so that the thicker transversal fibers provide more support to the longitudinal fibers to enhance the attachment of the wick to the heat pipe.

2. The wick structure of claim 1 , wherein the fibers are made of copper.
