And the two are connected to form a porous capillary guide F, as shown in Fig. 2F, and the total is taken out from the body U. Please refer to Figure II. Finally, the total field in the pipe body 12 is injected into the working body 12 to complete a working flow, that is, the pipe, the air, as shown in Fig. 3, and the open end of the pipe body 12 is sealed. Metal powder, a surface _ , , , , copper metal powder, a nickel metal powder, a silver ❿ 。. Gold, nickel or silver gold cores and other similar metals. In a specific embodiment, a plurality of fine scores have a layer on the inner wall of the tube having the flat end face. By having the flat wall around the upper axis - initial? Pore capillary drainage includes the following steps. First, the method of manufacturing the heat pipe made of the H body is smaller than one of the diameters of the pipe body, and the powder is placed in the pipe body, and the metal powder is sized. Then, the rod is inserted into the tube from the open end of the tube body and the initial porosity of the tube is surrounded by a sintering process to cause the metal powder to be separated from the closed end of the tube tube. The laminar phase is welded to form a cover comprising the metal body and taken out, using a thin tube-shaped capillary drainage layer. The center rod is filled with a working fluid from the inside of the tube. At last! 1295365 The inside of the tube is evacuated and the open end of the tube is sealed to complete the heat pipe with a flat end face. In a specific embodiment, the manufacturing method of the pipe made by the pipe body having the flat end face is formed by using a boring machining process on the inner wall of the pipe body to form a plurality of small nicks to form A porous capillary drainage layer. A working fluid is injected into the body of a thin tube. Finally, the inside of the tube is evacuated and the open end of the tube is sealed. In a specific embodiment, a method of manufacturing a heat pipe made of a pipe body having the flat end face is as follows. First, a plurality of metal particles are sintered on the inner wall of the pipe body, and a metal mesh body is disposed on the inner wall to form a porous capillary flow guiding layer. Similarly, a working stream is injected into the tube using a capillary tube, and the tube is evacuated. Finally, the open end is sealed, that is, the heat pipe having the flat end surface is completed. In a specific embodiment, a method of manufacturing a heat pipe made of a pipe body having the flat end face is as follows. First, a corrugated metal cloth (MZtal wir'e cloth) is laid on the inner wall of the pipe body. A flat metal mesh layer is disposed on the inner wall to form a porous capillary flow guiding layer. A working tube is injected into the tube body by a thin tube, and the inside of the tube is evacuated to seal the open end. The corrugated folded metal cloth may have a triangular shape, a rectangular shape, a ladder shape or a wave shape. In a specific embodiment, the flat end face is a lithographic shape or a groove shape. The official system is made of a copper metal, a nickel metal, a silver metal or the like. In one embodiment, the electronic component to be bonded to the heat pipe may be a Light Emitting Diode (LED), a Laser Diode, or an integrated circuit. (1C). In the application of the flat end face of the stamped pipe body in the application, it may cause the pipe body to rupture because the deformation amount 1295365 is too large. By heating the pipe body and increasing the deformation capacity of the material by hot pressing, the pipe body can be prevented from being cracked.
