Abstract: A heat pipe has a pipe container and a fiber wick structure. The fiber wick structure is arranged on an inner wall of the pipe container, and the fiber wick structure has at least two kinds of fibers with different melting points. Furthermore, when the fiber wick structure is manufactured in a sintering process, the higher melting point of fiber provides a support force for the fiber wick structure coupled to the inner wall of the pipe container, and the lower melting point of fiber is melted in the sintering temperature of the pipe container to adhere to the higher melting point of fiber on the inner wall of the pipe container.

Abstract: A method for forming an end surface of a heat pipe and the structure thereof are disclosed. Firstly, the mold module is provided for placing the heat pipe therein. The mold module includes a mold chamber to receive the heat pipe. Then, an extruding shaft is pushed forward into the mold chamber from an end of the mold module. Next, the ends of the heat pipe are compressed via the extruding shaft to render the end surface of the heat pipe depressed from outside to inside. Thereby, the heat pipe with a non-protrudent end surface is obtained. As such, the volume occupied by the useless segment of the heat pipe is effectively reduced, or, the heat pipe having a certain length to cooperate with more heat dissipating fins.

Abstract: A composite wick structure of a heat pipe includes wick structure fabricated from a woven mesh and sintered powder. The woven mesh is attached to an internal sidewall of a tubular member, while the sintered powder is coated on at least one side of the internal sidewall. By the better capillary force provided by the sintered powder, the liquid-phase working fluid can reflow to the bottom of the heat pipe quickly to enhance the heat transmission efficiency. Further, the problems of poor capillary effect of the woven mesh and the problems caused by usage of an axial rod during the process of applying sintered powder can be resolved.

Abstract: A wick structure of a heat pipe includes a wick structure attached to an internal wall of a tubular member. The tubular member is fabricated from metal material with good conductive characteristics, and the wick member is formed of a mesh structure and a plurality of particulate members. The mesh structure is in the form of a ring attached to an internal wall of the tubular member, and the particulate members are embedded in the interstices of the mesh structure. The wick structure is attached to the internal wall of the tubular member by sintering, such that a wick structure with a villiform structure is formed. Thereby, the peeling or fracture tendency of the wick structure during the mechanical process of the heat pipe avoided. In addition, the axial rod used for the sintering process is not required, such that the cost is greatly reduced.

The heat pipe includes a pipe member, a lid, a base and a wick structure. The hollow tubular pipe member has two opposing open ends. The lid is closely covered on one open end. The base provides an interlocking member including a flange fitly embracing the pipe member to receive the other open end of the pipe member thereinside. The wick structure is attached on an inner wall of the pipe member and an inside surface of the base. Moreover, the thickness of the flange is not larger than the thickness of pipe member at the open end received in the interlocking member. When the base is fitted with the pipe member at the open end, a welding process is performed to permanently connect them together. In the welding process, the flange of the interlocking member is enforced to be liquefied first and is liquefied more than the pipe member at the open end.
