Manufacturing method of thin heat pipe

Abstract

A manufacturing method of thin heat pipe includes steps of: providing a hollow tubular body and a mesh capillary structure; placing the mesh capillary structure into the tubular body; providing a tool and placing the tool into the mesh capillary structure; sintering the tubular body to make the mesh capillary structure sintered on an inner wall face of the tubular body and then taking out the tool; vacuuming the tubular body and filling a working fluid into the tubular body; sealing the tubular body; and pressing and flattening the tubular body into a flat form by means of mechanical processing. According to the manufacturing method of thin heat pipe, the mesh capillary structure can fully tightly attach to the inner wall face of the tubular body to keep the completeness of the tubular body and the completeness of the vapor-liquid circulation passageways in the heat pipe.
