Description of the new type: [Technical field to which the new type belongs] This creation relates to a heat sink with thinner fins, especially a thinner fin that can be made to increase the density of the fins. '' With a large heat dissipation area, the heat dissipation efficiency is effectively improved, and the width of each groove and groove of the base does not need to be correspondingly narrowed, which makes the groove processing easy, and it is made into a reduced heat dissipation device. [Previous technology] It is appealed that with the rapid development of the computer industry, the execution speed of heat sources such as chips and central processing units (cPU) is getting faster and faster, and the heat generation of the relative heat sources is getting higher and higher. The generated high temperature is discharged to the outside _, so that the heat source can operate normally at the permitted temperature. Generally, a radiator with a large area is attached to the overflow surface of the heat source, which is assisted by the multiple fins of the two heat sinks. Cooling. As shown in the first figure, most conventional heat sinks 9 include a flat base 9 1 and a plurality of knots 9 2 'The base 9 1 and the deaf cymbals 9 2 are made of copper or inscription The base 9 1 has a plurality of parallel grooves 9 1 1, and the fins 9 2 are sheet-like bodies, and the lower edges of the fins 9 2 are arranged. Into the grooves 9 1 1 of the base 9 1, * The fins 9 2 are fixed to the base 9 1 by appropriate methods such as clamping and welding, and the fins 9 2 are arranged at intervals. On the base 91, the distance between each fin 92 and the fin 92 is d. In order to enable the heat sink 9 to have a large heat dissipation area and thereby improve heat dissipation efficiency, the fins 92 can generally be made to a thin thickness (as shown in the second figure), and each fin 92 and the fins A larger number of fins 9 2 can be set under the principle of maintaining the same distance d M283222, thereby increasing the density of the fins 9 2 and making the heat sink 9 have a larger heat dissipation area, thereby effectively improving the heat dissipation efficiency. . However, the fins 9 2 are made thinner, and the widths of the grooves 9 and 1 1 of the base 9 1 must be correspondingly narrowed. However, the narrower grooves 9 1 1 are not easy to add and will increase. The difficulty of production makes the production cost increase. 'Therefore, from the above, it can be seen that the above-mentioned conventional heat-dissipating device has obvious inconveniences and defects in practical use ~ and can be improved. The reason for this is that the author felt that the above-mentioned shortcomings could be improved. However, he devoted himself to research and cooperated with the application of theories to finally propose a rationally designed and effective improvement of the above-mentioned original works. _ [New content] The main purpose of this creation is to provide a heat sink with thinner fins. The fins can be made thinner so that the density of the fins is increased and the heat sink is larger. The area of heat dissipation, so that the heat dissipation efficiency is effectively improved. This creation is to partially bend the fins to form a rebend, so that the local edges of the fins are thicker, so that the grooves of the base can be made corresponding. The wider width makes groove processing easier, reduces the difficulty of making the groove, and reduces the production cost. ~ In order to achieve the above purpose, the present invention provides a heat dissipation device with thinner fins, including: a base provided with a plurality of grooves arranged at intervals; and a plurality of fins whose partial edges are bent to form a reflection The folds are stacked on the surface of the fins so that the local edges of the fins are thicker than the fins. The fins are received and fixed to the corresponding bases with the local edges and the folds In the trench. M283222 In order to better understand the characteristics and technical contents of this creation, please refer to the following detailed description and drawings about this creation, but the drawings are for reference and explanation only, and are not intended to limit this creation. [Embodiment] Please refer to the third, fourth and fifth drawings. The present invention provides a heat sink with thinner fins. The heat sink includes a base 1 and a plurality of fins 2, wherein The base 1 is made of a metal material with good thermal conductivity such as copper # or aluminum. In this embodiment, the base 1 includes a central Φ section 11 and two corresponding ones extending from the central section 1 1 respectively. Side wing segments 1 2. The base 1 is provided with a plurality of grooves 1 3 '. The grooves 1 3 are arranged at equal intervals on the central section 11 and the wing section 12, and the top edge of each groove 13 And the two ends are open 5 for easy assembly * The fins 2. • The fins 2 are sheet-like bodies, the fins Z are made of metal materials with good thermal conductivity such as reference signs or inscriptions, and the fins 2 are made of thinner thickness. The partial edge of the fin 2 is bent to form a refolded portion 2 _ 1, which is provided at the local edge where the fin 2 and the base 1 are joined, that is, the refolded portion 21 is provided at The lower edge of the fin 2, the refolded part 2 1 series: placed on the surface of the fin 2 in reverse folding, so that the local edge of the fin 2 forms a thicker thickness than the fin 2-the folded part 21 is stacked on the fin 2 On the surface, the thickness of this part is twice the thickness of the fins 2, and the grooves 13 of the base 1 can be made to have a correspondingly wide width. When the creation is to be combined, the base 1 needs to be completely softened by heat treatment, and the temperature required for the heat treatment operation is between 1 000 ° c and 1100 ° c, so that the partial edges and reflexed portions of the fins 2 2 1 can easily accommodate 7 M283222 in the corresponding grooves 1 and 3, and then apply an average force from the two corresponding sides of the base 1 to deform each groove 1 3 to clamp the fins 2 The local edge and the reflexed part 21 make the fins 2 fixed on the base 1; the above-mentioned composition is used to form the heat sink with thinner fins of this creation. -The above-mentioned external force is applied from the two corresponding sides of the base 1 to make the grooves 1 3 • The fins 2 are deformed and clamped, and the fins 2 are fixed on the base 1 for the purpose of this creation only The preferred embodiment is not limited to this fixing method, and the fins 2 can be fixed on the base 1 by welding or other methods. The fins 2 of this creation can be made thinner, so that each A larger number can be set between the fins 2 and the fins 2 under the principle of maintaining the same distance d (as shown in the fifth figure), so that the density of the fins 2 is increased, so that the heat sinks have greater heat dissipation. Product 5 is thus effective for heat dissipation-improvement. In addition, in this creation, the fin 2 is partially bent to form a refolded portion 21, and the refolded portion 21 is stacked on the surface of the lower edge of the fin 2, so that the lower edge of the fin 2 is formed into a thicker thickness. In this way, the grooves 13 of the base 1 can be made to have a relatively wide width, so that the fins 2 can be made to a relatively thin thickness. The widths of the grooves 1 and 3 of the base 1 do not need to be changed correspondingly. Narrow, the grooves 1 3 ′ of the base 1 can still be made into a wider width, so that the processing of the grooves 13 is easy, the difficulty of manufacturing the grooves 13 can be reduced, and the manufacturing cost is reduced. In summary, this creation is a rare new creative product, which is extremely industrially usable, novel, and progressive, and fully meets the requirements of the new patent application 'application under the Patent Law'. Grant the patent in this case to protect the rights of creators. 8 M283222 The above is only a preferred and feasible embodiment of this creation, and it does not limit the scope of the patent for this creation. Therefore, any equivalent structural changes made by using this creation manual and the contents of the drawings are included in the same way. Within the scope of this creation, together with Chen Ming. [Brief description of the drawings] The first figure is a sectional view of a part of a conventional heat sink.
