Description of the Invention: [Technical Field] The present invention relates to a heat sink having a radiation-shaped heat sink, in particular, a first convex portion which is deformably deformed in a groove of a seat body, and a heat sink A compression bond is formed to provide heat dissipation for a central processing unit (CPU), a light emitting diode (LED) luminaire, or other heat generating unit. [Prior Art] A heat sink having a plurality of radiating fins is known, for example, in Japanese Patent No. 1269146, a plurality of fins are integrally formed on a peripheral wall surface of a tubular body, and each fin is radiated. The erected, tubular seat - can be implemented as a circular, square or any other shape of the tube, but the heat sink is a one-piece heat sink. The overall manufacturing is of course difficult and inconvenient, and the cost is also biased. High, the heat sink body is relatively thick, so the weight is very heavy, and the heat dissipation effect is not ideal, it is difficult to achieve practical level. The composition of the radiator and the radiating fin of the above-mentioned heat sink is not only integrated, but also by welding to complete the bonding, but the effect of welding and bonding is obviously not good, so some people insert the fin into the tubular seat. The groove is formed by inserting and implanting; or a stamping is applied to the end surface of the groove, and the heat sink is squeezed by the pressure deformation of the end surface of the groove, and the aforementioned pressing is clamped, and if the heat sink is inserted in front, there is no In the end, or because of the bounce of the stamping vibration, it is easy to cause the root of the heat sink to not completely fall into the groove bottom of the groove, so not only can not obtain a stable positioning, but also easy to produce heat sink height is not uniform In the defective phase, the fins may also be angularly offset, causing looseness or falling off. 201038903 [Summary of the Invention] The main purpose of the present invention is to provide a solar heat-fixing blade having a radiation-shaped heat sink, which comprises a heat sink formed by a tubular body and a plurality of plane-injection directions. A plurality of axially adjacent grooves are formed on the peripheral wall surface of the tubular seat body, and a first groove is provided on one side of the groove wall of each groove, and the bottom end of the heat sink has an f-fold portion for matching the heat sink After planting the groove, the first convex portion is deformed by using the stamping die (4), and the material portion of the heat sink is forced to be pressed to form a good compression joint, since the s-shaped portion after the deformation passes through the heat sink (4) Folding part, therefore, it can ensure that each heat sink can be fully inserted into the groove bottom of the groove, and the most stable joint positioning is obtained, and each heat sink inserted in the radiation direction can be accurately pressed to the bottom. The implantation of the sheets must be the same equal height, and there will never be a case where the heat sink distribution is different. A secondary object of the present invention is to provide a heat sink design having a radiation-shaped heat sink. The tubular seat body can be further provided in the groove groove on the side of the groove groove wall except for the first convex portion. A second protrusion is also added to the other side of the wall. Therefore, when the heat sink is inserted into the groove to complete the compression bonding, the second protrusion forms abutting contact with the heat sink body, so that the heat sink can be more effectively prevented. The angular offset is not correct. A further object of the present invention is to provide a heat sink having a light-radiating heat sink, wherein the bent portion at the bottom end of the heat sink can be any bending angle equal to or greater than 90 degrees, and correspondingly implanted. Matching grooves on the tubular seat. Another object of the present invention is to provide a heat sink having a radiation-shaped heat sink, the body of which is not limited in thickness, but is implemented as a sheet-like shape of 201038903 $ heat sink, which can be disposed at the bottom end of the sheet-type heat sink. There is a fold-folded % fold to increase the strength of the bottom end, and the folded portion of the fold fold can also be implemented as any bend angle equal to, greater than or less than 90 degrees for implantation and bonding. Matching grooves on the body. A further object of the present invention is to provide a heat sink with a radiating fin which can be implemented as a circular, square or arbitrarily shaped tube body as needed, and the tubular seat The body may be a solid tubular body or a hollow tubular body or a tubular body having a u-shaped cross section. Still another object of the present invention is to provide a heat sink having a radiation-shaped heat sink which is very suitable for use in extrusion technology or by stamping and drawing techniques to form a plurality of grooves on the pipe wall. The groove and the first convex portion, or the second convex portion, can simplify the overall manufacturing, and are suitable for mass production and reduce the cost thereof. [Embodiment] The structural features and other functions and objects of the present invention are described in detail below with reference to the accompanying drawings: ❹ As shown in the first and second figures, the present invention is designed as a "radiator with a radiating fin". The instrument includes a tubular body and a plurality of fins 2, wherein: Μ the tubular seat body 1 defines a plurality of axially adjacent grooves 1 on the peripheral wall surface of the seat body and a groove wall of each groove 11 The side is provided with an upward convex portion 12; a plurality of heat sinks 2 are inserted around the tubular body 呈 in a radial direction, and a bent portion 21 is formed at the bottom end of each heat sink 2 (such as the second figure) And the bent portion 21 can be matched to the groove u ^ ' 5 201038903 implanted in the tubular seat body i. The above-mentioned tubular seat body 1 and the plurality of heat sinks 2 are used, and the heat sink 2 is matched with the implant seat. After the groove 11 of the body 1, the pressing of the stamping die 3 (as shown in the fourth figure) can be forced to deform the first convex portion 12, and the bending portion 21' of the heat film 2 is pressed to form a good shape. The downward pressing force of the first convex portion 12 can press the bending portion 21 under each I pressure deformation, so that the f-political heat film 2 can The bottom of the groove that is completely inserted into the groove u is firmly combined, and it can ensure that each of the fins 2 has the same equal height after being implanted, and the angular offset or the combination is not stable. As shown in the above embodiment, the heat sink 2 is formed by using a sheet-shaped metal sheet body to match the first protrusion portion 12 of the seat body i to form a pressing sheet type heat sink 2 because the sheet thickness is thinner. Therefore, the bent portion 21 at the bottom end of the sheet-type fin 2 can be formed in a folded-folded shape to strengthen the strength of the sheet-type fin 2 and the first-protrusion portion 12 by press-bonding. In addition, the outer ends of the fins 2 in each of the sheets may have a more passivated folded-back portion 22 to prevent the sheet-type fins 2 from being sharply cut due to the sharp front end. As shown in the fifth to seventh embodiments, the tubular seat body 1 of the present invention is further provided with the first convex portion 12 on the side of the groove wall of the groove 11 and further in the groove 11 The other side of the groove wall is also provided with a second convex portion 13 extending upward (as shown in the eighth or ninth view), so that when the diffuser sheet 2 is inserted into the groove u and passed through the underside of the mold 3 The bent portion 21 of the heat sink 2 is tightly combined with the deformed first convex and convex formation, and the second convex portion 13 can provide the sheet of the heat sink 2 as a good abutting (such as the portion of the tenth figure) Display), through this design of the abutment, it can ensure that the angular offset of each hot film 2 will not occur after the combination, so that each heat sink 2 can be kept straight and will not shake. Or fall off. According to the foregoing embodiment, the plurality of fins 2 may further have one or more sets of clasps on the upper or lower end faces, and the front and rear adjacent cleats 23 are fastened and coupled to each other. The plurality of fins 2 can be a tighter junction. The tubular seat body i of the present invention, although the embodiment is shown as a circular pipe body 'in fact, the shape or size of the tubular seat body is changed from the visual need, for example, as a rectangle or a rectangle. Elliptical, diamond or any other shape of the tube is also a feasible seat. Further, the tubular seat 〇y can be a U-shaped tubular body (as shown in FIG. 11), and a locking hole (4) can be opened on the closed surface 14 of the tubular body for heating element or electronic component lock The joint body 1 or the tubular seat body 1 may also be a solid pipe body (such as the twelfth figure). Of course, it may also be the shape of the hollow pipe body, so the actual shape of the tubular seat body is not special. The need for restrictions. As shown in the thirteenth to fifteenth drawings, the various aspects of the bent portion 21 at the bottom end of the heat sink 2 are mainly disclosed. The bending angle of the bent portion (4) can be equal to, less than or greater than 90 degrees, and each The matching groove _ groove bottom also has an angle corresponding to the fit 〇. In addition, the heat sink 2 of the present invention is also not limited to the use of a sheet metal sheet, for example, as shown in the thirteenth to fifteenth drawings, that is, a general metal sheet is used as the heat sink 2, similarly. It is also possible to insert the groove U' which is coupled to the tubular seat body 1 and form a pressing combination with the deformation of the first convex portion 12, or advance through the second convex portion 12 to obtain a good resistive support. The tubular seat body as described in the present invention may be U-shaped, solid, hollow, and the like in terms of its shape, size, or body, and is all practical and suitable for the tubular seat. In terms of manufacturing, it is very suitable to adopt the extrusion technique or the technique of punching and stretching, and form 7 201038903 into the plurality of grooves 11, the first convex portion 12 or the second convex portion 13 on the pipe wall, so The molding manufacturing of the tubular seat body 1 can be simplified, which is suitable for mass production and effective cost reduction. In summary, the present invention is directed to a planting combination of a heat sink and a tubular seat body, and the structural features thereof are significantly different from those of the conventional heat sink system, so that the heat sink can be completely inserted into the tubular seat groove. The bottom of the groove is very stable. It can ensure that each heat sink maintains the same height and there is no angle skew. It has been progressive.
