Description of the invention (1) [Technical field to which the invention belongs] The purpose of the present invention is to provide a method for combining a heat pipe and a radiating fin, in particular It refers to a bonding method for reducing the bonding gap between a heat pipe and a heat dissipation fin. [Previous technology] Computer has become an indispensable tool in many industries. With the continuous increase in demand, the computer industry has developed rapidly and greatly. The performance of computers depends largely on the central processing unit, its speed and stability. It directly affects the performance of the whole machine. The higher the central processor's integration and the faster the operating fan speed, the greater the heat generated by it. If the heat is not released in time, the heat will increase and its temperature will increase. It greatly affects the stability of its operation. Therefore, it is necessary to dissipate the heat generated by the CPU in a timely manner. The industry usually installs a radiator on its surface to assist heat dissipation. As shown in the first figure, it is disclosed in U.S. Patent No. 5,4 丨 2,5,35 ~~ A heat pipe radiator 100 commonly used in the industry, the radiator 100 has a flat base 120, a The heat pipes 140 are vertically fixed on the base 120, and a plurality of heat sinks are arranged. The sheets 160 are arranged in parallel at a certain interval and pass vertically on the heat pipes 140. In order to combine the heat pipe 140 with the heat dissipation fins 160, it adopts the method of hydraulic or mechanical expansion, that is, the heat dissipation fins 160 are set on the heat pipe 140 before molding, and a mandrel or internal liquid is used to pressurize it. The expansion pipe body increases the diameter of the heat pipe, and the interference between the heat pipe and the heat dissipation fins is achieved. However, since the heat pipe 140 and the heat radiating fin 160 are in mechanical contact, due to the existence of the gap, they cannot be uniformly adhered. Therefore, the heat transfer effect between the heat pipe i 4 〇 and the heat radiating fin 160 is poor, and the high conduction of the heat pipe 丨 60 The characteristics are not fully exerted, the overall performance of the radiator 100 is affected, and this method cannot be used

Description of the invention (2) Assembled heat sink with molded heat pipe. In order to use a heat pipe to assemble the heat sink, and to enable the heat pipe and the heat sink fins to be evenly and seamlessly bonded, some people use a thermally conductive adhesive to bond them. stable. Therefore, nowadays, the industry often uses a soldering method to fuse the heat pipe and the heat dissipation fins. First, the heat dissipation wrong fins are provided with perforations with folded edges. One method is to first arrange a plurality of heat dissipation fins in abutment order. Then, a channel is formed by perforation, and a solder paste is coated in the channel, and then a heat pipe is passed through the channel. The heat pipe and the heat dissipation fins are welded together with the solder paste, but the solder paste is coated on the inner wall of the long tubular channel. It is not easy, and the solder paste is easy to get in the process of wearing the heat pipe. The solder paste cannot be completely and evenly filled in the gap between the heat pipe and the heat dissipation fin. Another method is to first put the heat dissipation fins on the heat pipe one by one. When each heat dissipation fin is installed on the heat pipe, solder paste is applied at the edge of the hem, and then another heat dissipation fin is put on. Since the paste is performed at a distance from the installation of the heat dissipation fin, the assembly process is cumbersome and efficient. It is quite low, and the method is likely to cause the solder paste to be squeezed out and cause the utilization rate to be reduced, thereby affecting the combination effect of the heat pipe and the heat dissipation fin. Therefore, it is necessary to provide a method for uniformly and tightly combining the heat pipe and the radiating fins, which can meet the requirements of rapid and convenient production and assembly, and also make the heat sink have good heat conduction performance. [Content] The object of the present invention is to provide a method for combining a heat pipe and a heat dissipation fin, and in particular, a method for reducing a bonding gap between the heat pipe and the heat dissipation fin. The method for combining a heat pipe and a radiating fin according to the present invention is firstly

Description of the invention (3) An opening is provided on the sheet; then the heat pipe is rotated and the heat sink fin is translated toward the heat pipe; when the opening of the heat sink fin contacts After the heat pipe, the rotation of the heat pipe is maintained to cause friction between the heat pipe and the radiating fins; the heat generated by the friction causes the friction surface to be plastically melted; pressure is applied to weld the openings of the heat pipe and the radiating fins together. The method for combining a heat pipe and a heat radiating fin of the present invention adopts friction welding of the heat radiating fin to the heat pipe. Since the heat pipe and the heat radiating fin are integrated by metal welding, there is no gap between the two, which solves the conventional heat pipe and heat radiation The problem of thermal resistance occurs between the fins, and the radiator made by the method provided by the present invention is also suitable for rapid mass production. [Embodiment] The method for combining a heat pipe and a heat dissipation fin of the present invention is applied to quickly and tightly connect the heat dissipation fin to the heat pipe.

Description of the invention (4) The gas becomes gas, which is transferred to the condensing end through the tube to release heat and condense to a liquid, which flows back through the capillary structure 26 of the tube wall. To the evaporation end, this cycle is achieved to achieve the purpose of rapid heat dissipation. As shown in the fourth figure, the heat dissipation fin 10 includes a rectangular plate body, and the lower edge of the plate body is folded into a folded edge 12. A semicircular opening α 1 4 is formed in the middle of one side edge of the plate body to weld the heat pipe 20. Referring to the second figure together, it can be seen that the heat dissipation fins 10 are arranged in pairs, and two heat dissipation fins 10 of each pair are symmetrical about left and right to be installed on both sides of the heat pipe 20. The material of the heat dissipation fins 10 and the material of the heat pipes 20 may be the same metal or different metals. The fifth and sixth figures are schematic diagrams of the process of installing the heat dissipation fin 10 on the heat pipe 20. The heat pipe 20 is fixed to a mandrel (not shown), and the heat pipe 20 is caused to rotate around its own centerline (that is, the centerline of the mandrel). The front fins 10 are folded against the fold 12, and the plurality of fins 10 are arranged one behind the other in order to form a fin group (as shown in the second figure, the fin group is also a pair of left and right symmetrical heat sinks. Fin group). The two symmetrical heat dissipation fin groups are held by a specific device, and are translated toward each other toward the rotating heat pipe 10. When the semicircular opening 14 of the heat dissipation fin 10 contacts the upper heat pipe 10, the heat pipe 20 continues to maintain its original movement, friction occurs between the heat pipe 20 and the semicircular opening 14 of the heat dissipation fin 10, and A large amount of heat is generated between the friction surfaces, so that the friction surfaces are plastically melted. At the same time, inward pressure is applied to the left and right heat dissipation fin groups, so that the heat pipe 20 and the heat sink fin 10 semicircular openings 14 are welded together. Since the heat pipe 20 and the heat dissipation fin 10 are integrated by metal welding, there is no gap between the two, thereby solving the problem of thermal resistance between the conventional heat pipe type heat pipe and the heat dissipation fin, and provided by the present invention. The radiator made by the method is also suitable for rapid mass production.
