Abstract
A heat pipe having a woven-wired wick according to the present invention is for improving a capillary force and permeability and simplifying the manufacturing process thereof. The heat pipe uses a wick in order to increase permeability. The heat pipe comprises a pipe body; and a wick having a larger diameter than that of the pipe body before being inserted into the pipe body and a smaller diameter than that of the pipe body after being inserted into the pipe body. The wick includes a plurality of groups of wires which are spirally woven to form a cylindrical wick and each wire is made of a material having an elasticity. In addition, the heat pipe is manufactured by the following steps: forming a cylindrical wick by weaving a plurality of wires spirally so that a diameter of the wick is larger than an inner diameter of a pipe body; and inserting the wick into the pipe body, wherein the diameter of the wick is smaller than the diameter of the pipe body and the wick is closely in contact with an inner wall of the pipe body without any process due to elasticity of the wire when the wick is inserted into the pipe body.
