The dotted circle in the middle indicates that the welded portions 1224, 142 are not present if the first opening 122 and the second opening 142 are threaded. But pay attention to the joint mouth. In the above specific embodiment, the ray 14 may include - the second and the second 1822. ! ^ Cover 148 groove 146 is formed with a --sintered metal layer turned on the cover mI to connect ί 弟 二 sintered metal layer. This groove 146 1822 is shown as three E. In addition, the description of the formation of the "cavity pattern", the injection molding process, the casting process, or the mechanical force: the machine hole 11 200840986 ... and the second hole capillary guide layer 28 will be described in detail. The inner wall of the cavity 24 of the crucible tube 2 has a plurality of fine H 282. The -* mandrel C2 is from the third opening 282 of the tubular body 22 of the heat pipe 2, such as the ^!-t finished scale f % Θ, and is substantially close to the plurality of small scores. Further, the first metal powder is etched between the center rod C2 and the semi-finished heat pipe 26, as shown in Fig. 4c. A sintering process is then performed to cause the young metal powder 284 to be fused to the plurality of fine scores 2 to form a porous capillary flow layer 28. Finally, the center rod C2 is taken out from the semi-finished tube 26. And after sealing the third opening 224, the thermal conduction is formed as shown in FIG. Incidentally, the center rod C2 does not have to have only one outer diameter, that is, the middle rod C2 may have different outer diameters. Referring to Figure 4E, Figure 4E shows a cross-sectional view of the heat pipe 2 according to a specific embodiment before completion. In comparison with the third embodiment, the heat pipe 2, the cavity 24, a plurality of small scores 282, and the inner tube of the heat pipe 2' have the same inner diameter. Therefore, a center rod having only a single outer row cannot simultaneously satisfy the plurality of fine scores 282, and a space is left between the center rod and the heat pipe 2, one of the semi-finished heat pipes 26, to accommodate The requirements for the addition of metal powder at the end. In this case, a central rod C2' needs to have a different control so that a part of the central rod C2' can abut the plurality of small scores 282, and between the central rod C2 and the heat pipe 2, There is a space to accommodate the second metal powder 284' added later, and in a subsequent sintering process, the second metal powder 284 is fused to the plurality of fine scores 282 to form a porous capillary guide The flow layer 28, as shown in Fig. 4F. And after sealing the semi-finished heat pipe 26, the heat pipe 2'' is formed as shown in Fig. 4g. It is worth mentioning that in the above specific embodiment, the cavity 24, 24 may include a recess 246 and an upper cover 248. The upper cover 248 includes a second 12 200840986 opening 242 of the cavity 24. The recess 246 is formed on the upper cover 248 with a second plurality of ridges - a plurality of small scores 2822. The upper cover 248 is engaged to form the cavity 2 small score 2824. The groove 246 and the score 2822 and the second plurality of thin, 24'' and the first plurality of fine scores 282 are as shown in Fig. 4H. Another 2824 forms the plurality of small powder metallurgy processes, a stamping process, and the groove 246 itself can be made by a mechanical processing process. The molding process, a casting process or a reference to Figure 5, Figure 5 is a schematic cross-sectional view of the root canal 3.

Only in the heat pipe 3, the mechanical processing process is used on the inner wall of the thermal guide hair = flow layer 3S = 2: r34, and the plurality of straight strips are manufactured in the same way: The other parts of the inner wall of the hot tube of the trace are subjected to a plurality of small indentations of a shape: a gentle capillary diversion layer. However, attention should be paid to the connection between the two sets of small nicks. $ Seen in a combined cavity, for example, a combination of 1_ and - top cover. Please refer to Figure 6 'Figure 6 series! The schematic diagram of the tube 4 according to a fourth preferred embodiment is shown. The heat pipe 4 is manufactured in a manner substantially 盥誃^^ the heat pipe 1_ of the specific embodiment, which will not be described herein. Only the manner in which the porous capillary guide layer 48 is formed will be described. A plurality of metal particles 482 are first sintered on the inner wall of the tube 42 of the heat pipe 4 and on the inner wall of the cavity 44 of the heat pipe 4. A metal mesh 484 is further disposed on the metal particles 482 to form the porous capillary flow guiding layer 48. Incidentally, the plurality of gold particles 482 can be burned to the inner wall of the tube 42 and the inner wall of the chamber 44, respectively. Referring to Figure 7, Figure 7 is a schematic cross-sectional view of a heat pipe 5 according to a fifth preferred embodiment. The manner in which the heat pipe 5 is made is substantially the same as the total porous capillary of the first embodiment of the present invention, and will not be described herein. The 582 of the heat pipe 5 is described in the way of the pipe. First lay a wave of continuous folded metal cloth on the wall. The inner wall of the re-inspection-system 52 and the cavity 54 of the heat pipe 5 are formed to form the i-hole layer 584 on the corrugated continuous metal cloth 582. The wave of the corrugated continuous metal cloth 582 is an angular shape, a rectangular shape, a ladder shape or a wave shape. Directed = f ' Figure 8A is a schematic cross-sectional view of a body 62 according to a sixth preferred embodiment. The first tubular body 62 has an open second closed end 624. This seal is difficult to 624, flat. The first tube body is for subsequent necking process. Moreover, since the wall of the first tubular body 62 is tightened in the necking system, the wall of the first tubular body 62 will be aggravated after necking. Therefore, in general application, the first tubular body 62 The wall thickness of the closed end 624 is much thicker than the wall of the neck prior to necking so that an overall uniform wall thickness is obtained after necking. However, this should not be limited to this. The first tubular body 62 is then necked to form a cavity 626 and a second tubular body 628' as shown in Fig. 8B. The cavity 626 includes the closed end 624, and the second body 628 includes the opening 622. One of the cavities 626 has a cross-sectional area that is larger than a cross-sectional area of the second tubular body. The cross-sectional area of the cavity 626 refers to the cross-sectional area of the closed end. Additionally, the cavity 626 and the inner wall of the second body 628 include a porous capillary flow guiding layer 64. The cavity 626 and the second tube 628 are evacuated, and a working fluid L2 is injected into the cavity 626 and the second tube 628. Finally, the opening 622 is sealed. The order in which the working fluid L2 is injected and the pumping is exchanged. After sealing the opening 622, the heat pipe 6 is completed as shown in Fig. 8C. According to the sixth preferred embodiment, only the thin neck type is subjected to hot working in a temperature range of 4 to 600 degrees, or is higher than the recrystallization temperature of the first tube 62 by about 200 degrees. Thermal processing is carried out within the scope. In addition, the porous capillary flow guiding layer 64 forms the porous capillary guide on the inner wall of the first tubular body 62 before the necking.
