DESCRIPTION OF THE INVENTION: TECHNICAL FIELD The present invention relates to a heat pipe sealing and pressing method, and more particularly to a method which can surely increase the sealing adhesion strength and reduce structural damage caused by processing. Γ 【Prior Art】 Two-press, conventional heat pipe sealing and pressing method, or slamming type, or direct compression, resulting in stress concentration and ductility reduction of the pipe body sealing part, in the continuation During the bending and flattening process, the seal is prone to cracks or deep structural damage, which greatly reduces the life of the heat pipe. As shown in the first, second and third figures, it is an example of the general heat pipe 1, 2, and 3 sealing methods, and the pressing method is performed by the male and female molds of the smooth surface (not shown) Show), in order to seal the nozzle, the metal nozzles 1 1 , 2 1 , 3 1 are excessively stretched, and the joint force is weak. When the internal pressure of the heat conduction φ tubes 1, 2, 3 is slightly higher, it is easy. The present invention is mainly aimed at improving the disadvantages of the above-mentioned conventional applications, increasing the sealing strength of the sealing, improving the pressure distribution of the heat pipe at the sealing and pressing working surface, and avoiding excessive processing. The structure of the heat pipe sealing portion is degraded and structural damage such as stress concentration is caused, and the sealing strength and the structural damage caused by the processing can be surely increased. 1288816, in order to achieve the above purpose, the present invention is a heat pipe sealing presser side, which is provided with a mold having a first and a second mold, and the first and second mold surfaces are further embossed to form There are a plurality of convex surfaces and depressions; the opening of the guide is placed between the first and second molds, so that the first and second molds are simultaneously pressed against the opening of the heat conduit by the convex and concave portions thereof. A plurality of seals are applied so that the openings are sealed by a plurality of joints of the first and second molds, and the metal of the heat pipe is stretched toward the plurality of convex surfaces and the concave portions to make heat A house flower sealing portion is formed at the opening of the duct. [Embodiment] The following is a schematic view of a mold according to the present invention, a partially enlarged schematic view of a fifth embodiment of the present invention, and a schematic view of the sealing of the present invention after the sealing of the present invention. As shown in the figure, a heat pipe sealing and pressing method of the present invention comprises the following steps: 4 ^^ a. providing - a mold having a first and second molds (left and right molds or male and female molds, f 2) 4' The first and second molds 41 and 42 are respectively formed with a plurality of convex surfaces 4 3 and recessed portions 4 4 by embossing treatment (as shown in the fourth, fifth and sixth figures, the first and second molds 4) The embossing treatment of the surface of the crucible 42 may be performed by the first mold 41 or the second second mold 42 (as shown in the seventh figure), or the first and second molds 4 1 and 4 2 have embossing treatment, wherein the The first and second modes are embossed by the embossing process, and the angle is between (4) q degrees, but 45 degrees is the best, and the design ratio of the majority of the convex surface 43 and the depression, and the depth of the depression, It is related to the quality of the person; the working condition of the hand mouth, metal material 1288816 b. The opening of the heat pipe 5 is placed between the first and second molds 4 4, 4 2, so that the first and second molds 4 1, 42 is sealed by simultaneously pressing the majority of the convex surface 4 3 and the recessed portion 4 4 at the opening of the heat pipe 5, so that the opening is at a plurality of points by the first and second modes 41, 4 2 Pressing force The mouth is tightly closed to form an embossed sealing portion 5 1 and the extruded metal is extended into the plurality of convex surfaces 43 and the recessed portions 4 4 , and the present invention can be used as the final sealing process of the heat pipe 5 . In order to achieve the airtightness of the opening, or as an intermediate process of the heat pipe 5, after the opening is closed, the welding and welding processes are performed to ensure that the sealing structure can conform to the subsequent deformation process such as bending and flattening. Strength requirement. If so, a new thermal conduction device sealing and pressing method is constructed by the above structure; the sealing pressing strength can be increased, the pressure distribution of the heat pipe 5 at the sealing pressing processing surface can be improved, and the excessive processing can be avoided. The structure of the heat pipe 5 is reduced in ductility and stress concentration, which can increase the sealing strength and reduce the structural damage caused by processing. The result of the press-sealing is shown in Figure 8. Please refer to the ninth. And the tenth figure is a schematic view of the square embossing pattern of the present invention and a schematic diagram of the triangular embossing pattern of the present invention. As shown in the figure: the first and second molds 4 1 and 4 2 are embossed on the surface. The embossed pattern may have a square shape, a rectangular shape, a rhombus shape or a triangular shape, so that the opening portion 5 of the metal pipe body 5 is formed with a square or triangular shape after the press-sealing. See the "11th image" The invention completes the result of the cutting and pressing sealing at one time. As shown in the figure: the embossing die design of the mold 4 a has a strong pressing ability, and can provide the function of cutting and pressing the sealing once, and a long strip The heat pipe is cut into several heat pipes of the same quality. 1288816 5. Please refer to the "Twelfth Diagram" for the result of the cutting and pressing seal of the present invention. The result is not intended. The press-and-clamp design provides a cutting function to cut the heat pipe 5 into a desired shape and simultaneously seal the press-fit slit to achieve the assembly size. Please refer to the "Thirteenth Diagram" for the embossing and perforation of the present invention. As shown in the figure: the embossing die design of the mold 4c has a strong 'solid pressing ability, and can be provided with a plurality of perforations on the heat pipe 5 during the pressing process of the heat pipe 5. 2 as a fixed positioning use. In summary, the heat pipe sealing and pressing method of the present invention can effectively improve various disadvantages of the conventional use, can increase the sealing strength of the sealing, improve the heat pipe sealing, pressurize the pressure distribution on the processing surface, and avoid heat caused by excessive processing. Structural damage such as reduced ductility and stress concentration of the sealing portion of the conduit can surely increase the sealing adhesion strength and reduce structural damage caused by processing, thereby making the invention more progressive, more practical, and more suitable for the user.
