Description of Invention (2). The above-mentioned manufacturing method of the cylindrical heat-conducting pipe is a metal pipe with easy heat conduction, usually a copper pipe, whose bottom end is sealed with a metal material with easy heat conduction, and then a central rod is inserted from the upper open end to place it in the metal pipe. In the center position, pour metal powder from the open end to add organic adhesive, and then perform a high-temperature sintering process to form a sintered layer on the inner wall of the metal tube. The center rod is pulled out, leaving a cylindrical hole at the center of the metal tube. Poured into the metal tube, this fluid can be distributed in the sintered layer by capillary phenomenon, and then the air in the metal tube is drawn out, and the open end of the metal tube is sealed to make the metal tube into an airtight cylindrical shape. The cylindrical heat-conducting tube 100 has been proven to have a fairly good heat-conducting and heat-dissipating effect in practical applications. However, this type of heat-conducting tube 100 often causes a decrease in heat-conducting efficiency due to process deviations. The most common problem is Due to the process deviation, the thickness of the sintered layer 14 in the heat transfer tube 100 is uneven, and the cylindrical hole 16 is not parallel to the heat transfer tube 100 column or is not located at the center of the heat transfer tube 100, as shown in the second figure and the first. As shown in the three figures, the heat conducting effect of the heat conducting pipe 100 is greatly reduced, so it is quite important to provide a manufacturing method of heat conducting pipe 100 and a jig which can obtain a uniform sintered layer 14. (3) [Summary of the Invention] The main object of the present invention is to provide a manufacturing method and a jig for manufacturing a heat transfer pipe, so that the manufactured heat transfer pipe has a uniform sintered layer. Another object of the present invention is to provide a manufacturing method for manufacturing a heat pipe, so as to avoid the problem that the heat pipe performance is reduced due to process deviation.

Description of the invention (3) Health. In order to achieve the manufacturing method and the fabrication process, the sintered metal is used, and then the middle wall is contacted to place the tube inside to lift off, and the inner wall of the tube is left with a heart. After completing the tube, the effect can be easily understood through the deviation. JL — sintering a two-component central metal to obtain a lead. 4 4 For the above purpose, the tool is made by inserting a core rod into the copper tube before the central metal powder. The reduction of the performance is due to the purpose of the invention. This invention is based on the stick-shaped organic adhesive on the surface of the rod; it is inserted into the copper tube, the core is added, and the sintered layer is formed at the high-temperature junction layer. The coordinated and technically proposed copper tube can be made into a rod and the powder can be added to the process body, drawn and shaped, and the attached drawings are made, and the special positioning can be made to make the bumps on the guide. Each bump passes through the bump. In the organic adhesive, the bumps emerge from the cylindrical hole of the central rod in a good performance tube, which can avoid the heat pipe heat pipe burning. The thickness of the bumps and the copper tube internal coating agent are only provided in the steel from the center, and then in the copper copper tube. The good thermal conductivity factor-free system is explained in detail 'Dangcian point and the implementation of the work achieved (four

Description of the invention (4) It is not uniform in the copper pipe, and the drawing is made. When the powder of the present invention is added with the bump 2 4, the inner wall of the 20 can be used for high temperature falling, and after the copper core rod 22 The center of the 20 is left as the center position of the heat pipe, and the adhesive for the heat pipe is put into the middle. Use this in advance to make the central sintering process tube 20, the inner wall of the copper tube 20, the next cylinder, and the copper tube 20 internal gas. Extract a metal powder with reliable quality and efficiency. In order to obtain a surface with a better level, the center rod can be accurately located with copper powder or aluminum powder. It can be manufactured by the above description. The method can be manufactured and the rod surface can be formed in advance. The heat conduction control device has the effect of reducing the efficiency, is easy, and can directly lead to the original heat dissipation efficiency of the sintered layer distribution in the prepared heat pipe. The sixth decision method is based on the process of processing copper pipe 20 In the process, several bumps 2 4 of the same thickness are made in advance in gold, and then the surface of the core rod 22 is set so that the center rod 22 is inserted into the copper tube 20. A bump 24 having a designed height is slightly contacted with the copper tube rod 2 2. It is located at the center of the copper tube 20, and then, the bump 24 can be de-sintered from the surface of the center rod 22 to form a sintered layer 26. The middle wall is pulled out to form a uniform sintered layer 26, and the copper tube is formed on the copper tube. Holes 28, as shown in the seventh figure. The next step is to inject a fluid into the copper tube 20, and then seal the open end of the copper tube 20 after the liquid is discharged, so as to obtain a heat-dissipating tube product without discount. The positioning effect of the bumps made by adding organic adhesive sticks to the center. The bumps should stick to the center rod, and the number of bumps should be more than three, with the copper tube centered. The metal powder is usually hot metal powder. In order to determine the positionable heat pipe metal powder added with an organic adhesive in the center, it is indeed possible to avoid heat pipe deviation due to process and the method proposed by the present invention is quite compatible with other processes of heat pipe without modification. other
