Description of the Invention: [Technical Field] The present invention provides a heat sink core tube holder and a method of manufacturing the same, the manufacturing process including extrusion molding and multiple-pass milling processing, which is a quantitative aluminum ingot The billet is formed into a hollow tube body with a closed end surface by extrusion molding, and then subjected to a plurality of punching processes for the outer wall of the hollow tube, and is punched to form a plurality of clip grooves which are vertically adjacent to each other at a high density. A plurality of heat sinks are provided to form a high density mating insert. 〇[Prior Art] A heat sink having a plurality of radiating fins is composed of a plurality of fins and a core tube joint, and a plurality of fins are attached to the core stem in an integrally formed manner. The outer wall surface enables the plurality of heat sinks to be formed in the radiation direction. However, since the heat sink is integrally formed, the overall manufacturing is complicated and inconvenient, and the cost is particularly expensive, and the thickness of the heat sink body cannot be thinned, and the heat sink is thick. Heavy, not only increase the weight, but also because the number of heat sinks is sparse, so the overall heat dissipation effect is not good. Ο The above-mentioned conventional radiation type heat sink is to abut the end surface of the core tube to the heat source (CPU or LED element) to achieve the heat dissipation effect, or may combine more than one heat pipe to improve the heat dissipation power, and the core The shape of the socket can be implemented as a circular, square or any other shape of the tube. In the above-mentioned conventional heat sink, the radiation fins of the radiation direction are also welded to each other by the welding method, and the heat sinks are attached to the outer wall surface of the core tube holder one by one, but the effect of the welding combination is obviously not good, which is time-consuming and labor-intensive. And it must be processed by electroplating for welding, so it is not environmentally friendly, 201043357 and will reduce the heat transfer effect; or some people use the solid slashed material to make the type of 'production process, which takes time and labor, and produces More waste, so the cost is high' is not economic. In addition, the 'student also has the use of a squeeze-type drawing method to draw the material into a large-sized hollow tube with a plurality of interlacing grooves on the outer wall = cut into a plurality of core sockets that are pierced. Xin insert,,. δ complex heat sink, but this conventional method still has the following shortcomings. (1) The method is based on extrusion drawing, so the number of outer slots of the core socket is relatively sparse, matching There are relatively few heat sinks, and the number of heat sinks is not dense enough. The dispersion::::: The number of grooves on the outer wall is increased, so it is easy to cause the bursting damage of the extrusion die, so it cannot be implemented. (2) Both ends of the tube seat are hollow, which is continuous: and: ΐΐ, must also be at the selected-open end to force the two to use the closing piece to abut the heat source seat body is not: body = stand 'but due to closure The heat transfer of the sheet and the core tube, the heat dissipation == therefore is extremely non-inventive] The main object of the invention is that the method of making the π and the If is to provide a punching of the core of the radiator core Second, the extrusion molding of the pressing die and the punching of the intermediate with the end-closed surface The ingot of the ingot is first extruded into the outer wall for the plurality of passes: the body of the body is punched and the outer wall of the body is punched to form a plurality of clip grooves having a high density and vertically adjacent distribution of 201043357. The core socket of the heat sink is configured to provide a heat sink with a high-density clip groove, which can quickly form a heat sink with a high-density heat sink. The second object of the present invention is The invention provides a radiator core socket and a manufacturing method thereof. Since the extrusion molding and the punching processing method are adopted, there is no waste of waste, and it is easy to be punched to form a high-density clip groove, which can densely increase heat dissipation. The setting of the sheet helps to improve the heat dissipation efficiency, and the cracking damage of the Ilu material does not occur, and the one end of the hollow tube body can be integrally formed with the closed surface by extrusion molding, so Capillary phenomena occur, so there is no obstacle to the transfer of heat. Another object of the present invention is to provide a radiator core socket and a manufacturing method thereof, wherein the processing operation for the outer wall of the hollow tube includes: rough punching, fine punching, fine punching, etc. In a plurality of processes, the outer wall of the hollow pipe body is passed through different punching tools, and after a rough punching, more than one fine punching and fine punching process is performed, and a plurality of Q grooves having a high density distribution can be punched. The trough, which is more simplistic and very fast to manufacture, is ideal for mass production and cost reduction. [Embodiment] The structural features and other functions and objects of the present invention will be described in detail below with reference to the accompanying drawings. As shown in the first figure, the present invention is a "radiator core socket and a manufacturing method thereof", which are mainly in sequence. By extrusion molding of the extrusion die and punching of the punching die, a predetermined amount of the aluminum ingot blank 1 (as shown in the third or fourth drawing) is formed by extrusion molding to form a closed surface 11 at one end. 5 201043357 hollow pipe body 1 ο, and # j Λ i type (such as the fifth figure and the hollow pipe body 10 is integrally connected to the empty pipe body U) C or the eighth to tenth figure), and then For the middle; == money multi-pass milling, so that the outer wall of the tube (such as the first figure between the drawing and the vertical adjacent distribution of the plurality of interlacing η thirteenth or fourteenth to the first The sixteenth embodiment is divided into: a heat-carrying (four) core socket 1〇0 and using the high density: the second 詈^2: 2 by " 'matching each heat sink 200 to form a tightly pressed embedded mr seven map or Figure 18), consisting of a heat sink 300 with a high-density political sheet (such as Figure 19 or Figure 20). According to the above-mentioned (4) manufacturing materials, the implementation steps are as follows: (1) Prepare the pre-quantified raw material 1; (2) · Use the above-mentioned quantitative blanking material 丨 'first squeeze through the extrusion die Press forming, thereby forming a hollow tubular body 10 (3) having a closed end surface 11 and performing a plurality of punching operations on the outer wall of the tubular body 1 (), so that the outer wall of the tubular body is punched Cutting a plurality of clip grooves 12 having a high density and vertically adjacently distributed to form a core tube holder 1 . As shown in the second figure, the present invention is directed to the blanking process of the outer wall of the hollow tube body 1 , The processing operation may include: a plurality of processes such as rough punching, fine punching, and fine punching, so that the outer wall of the hollow tubular body passes through different punching tools, and the rough punching is pre-exposed on the outer wall of the hollow tubular body 10. Cutting a predetermined number of tanks that have been modeled, the fine punching process is to further punch the rough-formed tank into a groove of a predetermined size, and finally correct the groove to a predetermined size by a fine punching process. The clamping groove 12, after a rough punch, passes more than one fine punch and one. 201043357 times The above-mentioned fine punching and the like, and the punching of the plurality of clip grooves 12 having a high density distribution, the overall manufacture is more simplified and very fast, so it is very suitable for mass production in a consistent operation, and can effectively reduce the cost. In the above-described extrusion molding process of the present invention, a plurality of columnar bodies 13 can be preformed on the inner wall of the hollow tubular body 10 (as in the fifth to seventh or eighth to tenth embodiments) And after the punching process, the plurality of columnar bodies 13 are drilled to form a plurality of keyholes 14 respectively (as shown in the eleventh or fourteenth embodiment) In order to provide the lock fixing position of the attached component, it can be seen that, in the implementation of the present invention, more than one keyhole can be opened on the closed surface 11 of the hollow tubular body 10 according to different requirements.
