Abstract

A heat pipe containing sintered powder wick inside and a corresponding manufacturing method improves the capillarity of the heat pipe. Through sintering copper powders on the surface of a copper wick, an evenly-sintered result can be obtained. Then the wick with sintered surface is placed into a hollow copper pipe to provide sufficient capillary force to the working fluid.
