Abstract: A heat pipe (10) includes a casing (12) and a sintered powder wick (14) arranged at an inner surface of the casing. The sintered powder wick is in the form of a multi-layer structure in a radial direction of the casing and at least one layer is divided into multiple sections in a longitudinal direction of the casing, and the multiple sections have powder sizes different from each other. The sections with large-sized powders are capable of reducing the flow resistance to the condensed liquid to flow back while the sections with small-sized powders are capable of providing a satisfactory capillary force for moving the condensed liquid.

Abstract: A method (50) for making a heat pipe (10) includes the following steps: a) providing a screen mesh (30) in the form of a multi-portion structure with at least one portion having an average pore size different from that of the other portions; b) rolling the screen mesh into a hollow column form; c) inserting the screen mesh into a hollow pipe body (22) of the heat pipe; d) sintering the screen mesh received therein at a predetermined temperature; and e) filling a working fluid into the pipe body and sealing the pipe body. The portion with large-sized pores is capable of reducing the flow resistance to a condensed fluid to flow back, whereas the portion with small-size pores is capable of providing a relatively large capillary pressure for drawing the condensed fluid from the condensing section to the evaporating section of the heat pipe.

Each supporting member includes a first surface, a second surface opposite to the first surface, and a longitudinal edge. A plurality of coupling elements are formed on each supporting member. Each coupling element includes a first portion on the first surface of an associated supporting member and a second portion on the second surface of the associated supporting member. The first portion and the second portion of each coupling element extend beyond the longitudinal edge of the associated supporting member and have a gap therebetween. The longitudinal edge of each supporting member extends into the gaps of the coupling elements. The longitudinal edges of the supporting members overlap each other when the coupling elements of the supporting members are engaged with each other.

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 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.

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.
