Abstract: A method and an apparatus for sintering metallic web heat pipe. The pipe body of a heat pipe is held by a fastening unit. A metallic web is then inserted into the pipe body. A core rod is also inserted to the metallic web, such that the metallic web closely contacts the pipe body. The heat pipe is then sintered in an oven. Since the melting point of the metallic web is lower than that of the pipe body and the core rod, the metallic web is combined with the pipe body during the sintering process. The fastening unit then moves the heat pipe to a blocking unit. After the core rod penetrates a hole formed on the blocking unit, a holding unit is used to clamp the core rod, thereby pulling the core rod off from the heat pipe. In this manner, a heat pipe having a metallic web combined thereto is manufactured.

The radially and axially arranged stripes are orthogonally stacked, thereby forming mutually communicable working fluid channels in the flattened portion of the heat pipe.

Abstract: A method and an apparatus for examining heat pipe temperature using an infrared thermography. The heat pipe is covered with a thin film. The heat transfer temperature of the heat pipe is examined and measured using an infrared thermography or an infrared imager. Since the presence of the thin film can provide a more stable and larger radiation emissivity of the heat pipe surface, a more accurate heat transfer temperature of the heat pipe can thus be obtained from the infrared thermography.

Abstract: A shrinkage-free sealing structure is formed at an open end of a heat pipe by pressing one side of the open end towards the other side of the open end until the side walls of the open ends contact each other. Furthermore, the recess is pressed to have a curve which is the same as the curve of the outer circular wall of the heat pipe so that a double-layered recess is formed with a cross-sectional length larger than a semicircumference of the outer circular wall of the heat pipe.

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.

The heat pipe includes a pipe member, a lid, a base and a wick structure. The hollow tubular pipe member includes two opposing open ends. The lid is closely covered on one open end. The base includes an interlocking member fitly engaged to the other open end of the pipe member and a flange extending radially and outwardly from the interlocking member. Moreover, the thickness of the flange is not larger than the thickness of pipe member at the open end receiving the interlocking member.

In the welding process, the flange is enforced to be liquefied first and is liquefied more than the pipe member at the open end. As such, it can ensure that the pipe member is prevented from being damaged during the welding process.
