The method of production. [Prior Art] [0002] According to the general circular tubular heat pipe, the tube body is also extruded into a flat shape instead of the flat heat pipe. However, in the conventional extrusion process, since the mold is necessarily a flat surface, the flat surface of the mold gradually changes to a surface contact when the pressure is applied to the heat pipe having a circular arc shape, but The initial point contact is prone to the problem of stress concentration, and thus a concave portion that is recessed inwardly is formed on the surface of the heat pipe to be pressed, so that the concave portion formed on the surface of the heat pipe is to be infiltrated into a flat shape, and the concave portion formed on the surface thereof will affect other The heating element or the heat sink element cannot be in full contact. [0003] In addition, in the past, the heat pipe is provided with a groove on the surface of the heat conducting seat in combination with the heat conducting seat, and then the round tubular heat pipe is buried in the groove by extrusion, and the heat pipe is pressed. The tube body is deformed to be combined with the groove forming effect, but the above method also has the above problem, that is, the heat pipe forms the recess on the pressed surface, and the surface Usually it has to be flush with the heated surface of the heat transfer seat, so the above problems and defects are also generated. In view of the above, the present inventors have made an effort to improve and solve the above-mentioned shortcomings, and have devoted themselves to research and cooperation with the theory, and finally proposed a present invention which is reasonable in design and effective in improving the above-mentioned defects. SUMMARY OF THE INVENTION [0005] The main purpose of the present invention is to provide a manufacturer of extruded heat pipes 099127492 Form No. 101 0101 Page 3 / 19 pages 0992048306-0 201208849 method, which is generated after the heat pipe is heated The vapor phase change can support the inside of the heat pipe body by the vaporized working fluid during extrusion to prevent the formation of the concave portion, and can make the heat pipe cooperate with the surface of the extrusion die to form a corresponding surface shape. [0006] In order to achieve the above object, the present invention provides a method for manufacturing an extruded heat pipe, the steps of which include: [0007] a) preparing a heat pipe internally sealed with a working fluid; [0008] b) making the heat pipe internal The working fluid generates a vapor phase change; [0009] c) pressing the heat pipe to form a desired surface shape on the heat pipe; [0010] thereby, the working fluid inside the heat pipe can be utilized to generate When the vapor phase changes, the pressure inside the heat pipe is increased, thereby preventing the concave surface from being generated on the pressed surface to achieve the above purpose. [Embodiment] [0011] In order to enable the reviewing committee to further understand the features and technical contents of the present invention, please refer to the following detailed description of the present invention and the accompanying drawings. It is intended to limit the invention. [0012] Please refer to the first figure, which is a flow chart of the steps of the present invention. The invention provides a method for manufacturing an extruded heat pipe, which can extrude a circular tubular heat pipe into a flat shape or embed the heat pipe into a heat conducting base; mainly using a working fluid inside the heat pipe to generate steam When the phase changes, the pressure inside the heat pipe is increased, thereby preventing the concave surface from being generated on the pressed surface, and the heat pipe can be matched with the surface of the extrusion die to form a corresponding surface shape. 099127492 Form No. A0101 Page 4 / 19 pages 0992048306-0 201208849 [0013] In the first embodiment of the present invention, the round tubular heat pipe 1 is extruded into a flat shape; please refer to the steps of the first figure S1, and in conjunction with the second figure: First, 'preparation—the heat pipe 1 in which the working fluid 10 is sealed internally; and since the present embodiment is an example in which the circular tubular heat pipe 1 is extruded into a flat shape, the heat pipe 1 should be a circle. Tubular. [0014] In the above, please refer to step S2' of the first figure and cooperate with the third figure: then 'make the vapor change of the working fluid 10 inside the heat pipe 1; that is, the original heat medium 1 is liquid phase The working fluid 10 is heated to make it a vapor phase working fluid 10. Wherein, the working fluid 10 inside the heat pipe 1 can be made to change the phase A, including but the town is limited; and the heat pipe 1, or the mold 2 to be used for pressing the heat pipe 后续, is heated and heated. To 80~200 t. ' j: |伊j{ [0015] Finally 'please refer to step S3 of the first figure, and cooperate with the fourth figure: cover the sea, ', and e 1 to form a heat on the heat pipe The shape of the surface is required, and the means for pressing the heat pipe 1 can prepare a mold 2 including the upper mold 2 and the lower mold 21, and since the heat pipe 1 is circularly drawn in this embodiment The housing is flat, so the sowing surfaces of the upper and lower molds are all one plane. After the heat pipe 1 is squeezed, since the working fluid inside the heat pipe 1 is filled with the vapor phase, the heat pipe 1 is internally formed. The pressure can prevent the concave portion from being generated when being pressed, so that the pressing surface of the mold 2 can be matched to form a corresponding surface shape; in this embodiment, the pressing surfaces of the upper and lower molds 20 and 21 are a plane, so the heat W after extrusion can form a flat center at the upper and lower sides to form a flat heat "that is, as shown in the fifth and sixth figures." [0016] In addition, the present invention can also The heat pipe is squeezed and buried on the heat conduction base 099127492 Form No. 1010101 Page 5 of 19 0992048306-0 20120884 9 , as in the second embodiment of the present invention; please refer to step si of the first figure, and cooperate with the seventh figure: first, prepare a heat pipe 1 and prepare a heat conduction for combining with the heat pipe 1 The heat-conducting base 3 has a heat receiving surface 30, and a heat-receiving surface is formed on the heat-receiving surface 30, and a heat-conducting medium is coated on the inner wall of the groove 31. The heat transfer medium is a heat conductive paste (not shown). [0017] Referring again, referring to step S2 of the first figure, and matching with the eighth figure: Next, the working fluid 10 inside the heat pipe 1 is also generated. The phase change causes the working fluid 10, which is originally in the liquid phase in the heat pipe 1, to be heated to make it a vapor phase working fluid 10'. The heated person can still be the heat pipe 1, or the mold 4 provided in this embodiment. And even the heat conducting base 3, and heated to 80~200 ° C. [0018] Finally, please refer to step S3 of the first figure, and with the ninth figure: the heat pipe 1 is squeezed to The heat pipe 1 is extruded into the recess 31, and a heat conducting base is formed on the heat pipe 1. The heating surface 30 of the heating surface 30 is flush with the pressing surface 12 to form a desired surface shape; wherein, the mold 4 used also includes an upper mold 40 and a lower mold 41, and the lower mold 41 is provided. There is a positioning groove 410 for positioning the heat conducting base 3 to facilitate the extrusion process. Moreover, when the heat pipe 1 is squeezed in this embodiment, the working fluid 10' inside the heat pipe 1 is also integrated into the vapor phase. The state is filled with the inside of the heat pipe 1, so that the pressing surface 12 of the heat pipe 1 after extrusion does not generate a recess, which is suitable for use in the manufacture of the heat pipe radiator (i.e., as shown in Fig. 10). According to the above configuration, the method for producing the extruded heat pipe of the present invention can be obtained. 099127492 Form No. A0101 Page 6 / 19 pages 0992048306-0 201208849 [0021] Therefore, by the manufacturing method of the extruded heat pipe of the present invention, it is possible to solve the problem of the concave portion caused by the conventional heat S being squeezed. Therefore, the surface of the heat pipe can be extruded into a desired surface shape, which can be more flattened, in particular, in order to provide a flat surface, thereby enabling the heat pipe to be contacted by the flat surface when directly attached to the original phase. In addition, the heat transfer effect is increased to exert the heat transfer efficiency of the heat pipe. [0022]
