Description of the Invention · Technical Field of the Invention The present invention relates to a method for forming a heat pipe and a heat sink fin, and more particularly to a combination of a side pressure pressing force and a pressing force. The heat pipe and the heat-dissipating fin 5 sheet forming method are used to improve the tight bonding and the yield, and the heat-dissipating device having the south bonding property and the heat transfer efficiency is prepared. [Prior Art] Φ It is known that heat sinks currently used in electronic components, especially heat sinks that require better heat dissipation efficiency, are distributed through a heat pipe and heat sink fins to quickly transfer electronic components. The generated heat energy is used for large-area heat dissipation. The design and manufacturing method of the heat pipe and the heat sink fin t will directly reflect the heat transfer efficiency and the heat dissipation rate, so there is a good combination tightness and production method, which will enhance the composition. Heat sink cooling performance. For example, in the invention patent of the "I5 combination method of heat pipe and heat sink" in the domestic patent publication No. 449514, the focus of the patent application is to apply a layer of solder on the joint surface of the heat pipe φ and the heat sink; After the heat pipe is joined to the heat sink, it is heated in a vacuum heating furnace to melt the solder during the heating process to cause capillary phenomenon to penetrate into the joint surface of the heat pipe and the heat sink to achieve a tight bond. In addition, in the patent case No. 1 2 3633 of the National Patent Publication No. 1 2 3633, the invention of the "heat pipe and heat-dissipation film / 20-shaped method", the focus of this patent case is on the part where the heat pipe is to be joined with the heat-dissipating slit, plating a metal heat conductive medium layer; b) bonding the heat sink fin to the portion of the heat pipe plated with the heat conductive medium layer; and c) heating the heat conductive medium layer to dissolve between the heat pipe and the heat sink fin, and then Line cooling. 5 1270339 m * In addition, in the invention patent case of "The combination method and combination structure of the heat sink fin and the heat conductor of the micro heat sink" in the patent publication No. 5 1 8927, the focus of the patent application is on the micro heat dissipation. The periphery of the heat pipe of the device is coated with a curing glue; before the curing glue is cured, the two sets of the two clamping pieces are respectively inserted into the gap between the two heat-dissipating pieces, and at the same time, the direction of the heat pipe is close to the pinch. The flange of the heat dissipation film is tightly joined to the periphery of the heat pipe. Each of the above patents utilizes a heat-fusible heat-transfer medium or a curing glue disposed between the heat-conducting tube and the heat-dissipating fin, and the heat-conducting tube and the heat-dissipating scale are combined with heating or pressurization, and the heat-conducting medium cannot be hooked. It is covered with 10 pieces of heat-conducting tube and heat-dissipating scale, or even knee joint, which is easy to form gap effect and heat transfer efficiency. Furthermore, there is a chemical substance in the heat-conducting medium and the curing glue, which is easy to cause danger to the human body and the environment. Patent Publication No. 1241156, "Method for Combining Heat Pipes and Buoyant Fins", the focus of this patent application is to set up on the (4) 15 f sheet - to open the heat pipe and make the heat pipe rotate and make The heat sink fins are directed to the heat guide. When the opening of the heat sink fin contacts the heat pipe, the rotation of the heat pipe is maintained to cause friction between the heat guide and the heat sink. The heat generated by the friction causes the surface of the friction and the heat to be Plastic refining state; pressure is applied to open the openings (4) of the heat pipe and the fins. However, although this method does not have the above-mentioned chemical substances harmful to the human body and the environment, but the plastic melting caused by the friction of the different metals still has the problem of uniformity of the plastic refining part, and it is easy to form the effect of the gap and the heat transfer efficiency. In addition, the industry's actual combination of heat pipes and heat sink fins ί ; = wear ι combination, as shown in the first and second figures, mainly the thermal conductivity s - heat conduction plate 12 - surface 'and obtained Most of the heat dissipating fins 13 are provided on the end surface of the hole 1 3 339 339, that is, the heat dissipating fins 3 are sleeved on the heat pipe 1 1 by means of the through holes i 4 to match the stamping parts and the automatic implements ( The drawing is not shown in the figure, and the punching process is used one by one, so that the heat dissipating fins 13 are tightly combined with the outer diameter of the heat pipe. However, the above-mentioned pressing and pressing manufacturing method, in addition to one-by-one pressing and pressing 5, is time-consuming. What's more, each fin 14 is subjected to the punching vibration of the implement and its through-hole manufacturing tolerance during the pressing process, which will affect the alignment and tightness of the heat sink 丄3 and the heat pipe 11. Each of the uncombined gaps 15 is generated at different positions, resulting in poor manufacturing efficiency, heat transfer efficiency, and poor heat dissipation. 10 [Summary] 15 The purpose is to solve the above-mentioned traditional defects and avoid the existence of missing. The present invention re-forms the heat pipe and the heat-dissipating film to form a heat-dissipating (four) surface through-hole and its ring-shaped wall design.
