Manufacturing method of heat pipe structure

摘要

A heat pipe structure and a manufacturing method of the heat pipe structure. The heat pipe structure includes a tubular body and a mesh body. The tubular body has a chamber. The chamber has a first side and a second side. A working fluid is contained in the chamber. The wall faces of the first and second sides are respectively formed with a first channel set and a second channel set. A first contact section and a second contact section are respectively formed at the junctions between the first and second channel sets and the wall faces of the first and second sides. The mesh body is disposed in the chamber and attached to the first and second contact sections. Accordingly, the thickness of the heat pipe is greatly reduced and the manufacturing cost of the heat pipe is lowered.

主权项

1. A manufacturing method of a heat pipe structure, comprising steps of:
providing a tubular body and a mesh body; forming at least one axial channel on each of a top wall face and a bottom wall face of an internal chamber of the tubular body, wherein the at least one axial channel is not formed on a right wall face and a left wall face of the internal chamber of the tubular body; placing the mesh body into the chamber, wherein the mesh body is placed in the whole internal chamber of the tubular body, but does not extend into the at least one axial channel, and wherein a right side and a left side of the mesh body are directly in contact with and attached to the right wall face and the left wall face of the internal chamber of the tubular body, respectively; pressing and flattening the tubular body; and vacuuming the tubular body, filling a working fluid into the chamber and sealing the tubular body.
