## Abstract

A wick structure of a heat pipe is constituted of woven meshes and fibers. The wick structure is constituted of two stacked layers of woven meshes and a plurality of fibers. The two woven meshes are adhered to the inner wall face of the heat pipe body, and each fiber is sandwiched between the two woven meshes and located on an axial stripe-like region within the heat pipe body. With a pulling rod, the woven meshes and the fibers can be driven to penetrate through the heat pipe body, so that the wick structure can be smoothly disposed into the heat pipe body.

## Claims

### Claim 1

A heat pipe body assembly having a wick structure, comprising:
a heat pipe body having an inner wall face; and
a wick structure constituted of two stacked layers of woven meshes and a plurality of fibers, the two woven meshes adhered to the inner wall face of the heat pipe body, the fibers sandwiched between the two woven meshes and located on an axial stripe-like region within the heat pipe body.

### Claim 2

A method for disposing the wick structure of the heat pipe, comprising the steps of:
a) providing two elongated stripe-like continuous woven meshes, a plurality of fibers and a heat pipe body for accommodating the two woven meshes and the fibers;
b) stacking up the two woven meshes so as to bundle and dispose the fibers between the two woven meshes;
c) curling one end of the two woven meshes along the width direction thereof, connecting said end of the two woven meshes together by means of a pulling rod;
d) penetrating the pulling rod into the opening of one end of the heat pipe body, penetrating out of the other end so as to curl the two woven meshes within the heat pipe body, and the fibers being sandwiched between the two woven meshes and located on an axial stripe-like region within the heat pipe body; and
e) cutting both ends of the heat pipe body, thereby to finish disposing the wick structure of the heat pipe.

### Claim 3 (depends on 2)

The method according to claim 2, wherein each of the two woven meshes is wrapped on a feeding wheel in the step a), thereby to proceed the continuous processing.

### Claim 4 (depends on 2)

The method according to claim 2, wherein the fibers are wrapped on a feeding wheel in the step a), thereby to proceed the continuous processing.

### Claim 5 (depends on 2)

The method according to claim 2, wherein the two woven meshes are curled via a curling mold in the step c).

### Claim 6 (depends on 2)

The method according to claim 2, wherein the two woven meshes are gradually curled to a curled form smaller than that within the heat pipe body in the step c).

### Claim 7 (depends on 6)

The method according to claim 6, wherein the two woven meshes are made into a curled form via a plurality of curling molds.
