Abstract

A sintered heat pipe in accordance with preferred embodiments of the present invention includes a metal casing and a sintered capillary wick arranged in the inner surface of the casing. The wick, which is formed by sintering metal powders, is a multi-layer structure in the radial direction of the casing and each layer is divided into many sections in the axial direction of the casing. The sintering process includes steps of filling metal powders of various sizes into the casing, using a mandrel to control the thickness of each layer and finally sintering the metal powders. Thus, a three-dimensional wick structure is formed in the heat pipe, which has improved performance in providing high capillary force and low resistance to working fluid contained in the casing.
