Abstract: A method is disclosed to produce a heat pipe with a sintered powder wick formed inside the heat pipe. The method employs tape-casting technology to firstly produce thin sheets of powder and then these sheets are sintered to form the wick. In the tape casting procedure, a slurry of the powders necessary to construct said wick is cast onto a moving surface to form a slurry layer and then the slurry layer is dried to form a green tape. The green tape is rolled onto a mandrel and then is inserted into a hollow casing and sintered to cause the powders in the green tape to diffusion-bond together. Thus, the sintered powder wick is constructed.

Abstract: A method is disclosed to produce a wick structure for a heat pipe. The wick structure is a sintered powder wick and is produced by sintering process. A group of powders is firstly provided. The group of powders is then classified into many sub-groups in terms of powder size. At least one sub-group of the powders is selected to form the wick structure via the sintering process. Thus, the powders used to construct the wick structure are confined to powders having a relatively narrower range of powder size in relative to the group of powders as originally provided. This has greatly reduced the complexity involved in the sintering process, and as a result, the required sintering temperature and the required time for the sintering process are easier to be determined.

Abstract: A screen mesh wick (14) and a method of making the same are disclosed. The wick is made separately and is adaptive for inserting into a heat pipe as a wick structure. The wick includes a plurality of elongated wires (141, 142) woven together and a plurality of protruding portions (145) formed on the wires. The protruding portions may be small metal powders attached to outer surfaces of the wires. The method includes the steps of weaving a plurality of wires to form a mesh (14?) firstly and then forming a plurality of protruding portions on the mesh, for example, by spreading the metal powders onto the mesh while the mesh is subject to heating. With these protruding portions formed on the wires, the effective pore size defined between the wires is reduced and therefore the wick is capable of providing a larger capillary pressure.
