Creation Instructions (1) [Technical Field of New Type] This creation is about a heat sink, especially a heat sink for heat-dissipating electronic components. [Previous Technology] With the continuous development of the electronic information industry, the operating speed of electronic components (especially central processing units) is constantly increasing. The heat generated by it will also increase. If it is not discharged in time, the temperature will continue to increase, which will affect the operating performance of the electronic components, including stability. To ensure that the electronic components can operate at normal operating temperatures, they are usually installed on the surface of the electronic components to dissipate heat. Device to remove heat. Aluminum extrusion heat sinks, which are widely used, undergo a series of processing procedures such as aluminum extrusion, cutting, trenching, hair removal, sanding, polishing, and anodizing to obtain the final structural form. Not only does this type of radiator produce more waste during the trenching process, but due to the limitations of the mold strength and related technologies, the ratio of the fin height to the groove width between adjacent fins is at most about 1 3: 1 When extrusion molding exceeds this limit, fracture, uneven thickness and deformation are prone to occur, so the heat dissipation area of the heat sink cannot be greatly improved, and its heat dissipation performance is gradually unable to meet the heat dissipation requirements of today's central processing units. As shown in the first figure, it is another more commonly used heat sink. The manufacturing process is obviously different from aluminum extrusion heat sinks. The heat sink is formed by continuous bending of a metal foil and the fixing seat 2 is attached. Made. The heat sink can overcome the problems that the aluminum extruded heat sink has a lot of consumables and cannot greatly increase the heat dissipation area. However, since the heat sink 1 series metal sheet is continuously bent, it is easy to shrink or open at the ends of the heat sink. Unstable phenomenon, which is troublesome for joining with the fixing base 2 and may affect the tightness of the joining. In addition, the heat sink 1

Creation instructions (2) A plurality of heat transfer surfaces 3 are formed to fit the fixed base 2. There is a certain distance between the heat transfer surfaces 3, and there is no heat dissipation on the surface of the fixed base 2 corresponding to these intervals. The sheet 1 is attached, and the area where the heat sink 1 contacts the fixed base 2 is only half of the area of the upper surface of the fixed base 2, which greatly reduces the heat transferred in a certain period of time and seriously affects the heat dissipation efficiency. [Content] The purpose of this creation is to provide a stacked fin heat sink with a stable structure and good heat dissipation. This creative stacked fin-type radiator includes a base and a plurality of snap-on stacked fins attached to the base. Each fin has a body, and the body is bent and extended with respect to two edges to form a hem, and the two ends of the hem continue to extend laterally to form a lap portion beyond the side edge of the fin body, and the front edges of the lap portions are opposite to each other. The bent part extends to form an extension part, which protrudes forward to form a buckle part, and the side edge of the buckle part forms a buckle ear, and the buckle part of the phase fin can be overlapped on the overlap part and the buckle The ear crosses the side edge of the fin and deforms under the action of the external force to be locked with the Korean piece body. At this time, the folds of each fin form a plane, which is in close contact with the surface of the base. Compared with the previous technology, this creation has the following advantages: The stacked fin heat sink of this creation is made of single-fin fins snapped on top of each other, and its structure is stable, and it will not loose or fall off when combined with the base. By increasing the height of the fins and reducing the fin pitch, the overall heat dissipation area can be appropriately increased, and the first folds of the fins form a plane to be combined with the base, and the contact area is increased, which is beneficial to the heat from Conduction from the base to the fins.

Creative Instructions (3) 4 $ See the second picture, this creative stacked fin-type heat sink can be in contact with a heating electronic element (not shown) to dissipate heat. The heat sink is composed of a base 10 and fins 20 of a plurality of snap-on stacks mounted on the base 10. Each of the shrink pieces 20 has a body 22, and the body 22 has two opposite edges. The folds 24 were perpendicularly extended in the same direction, and the side edges of the two ends of the folds 24 continued to extend laterally to form an overlap portion 30 beyond the side edge of the fin 20 body 22, and each fin 20 was overlapped. The leading edge of the portion 30 continues to bend obliquely towards each other to form an extension portion 2 6 'The leading edge of the extension portion 2 6 protrudes forward to form a buckling portion 2 8 because the extension portion 2 6 is a front edge of the 30 overlapping portion It is bent and extended obliquely. There is a certain gap between the buckle portion 28 and the overlap portion 30. The buckle portion 28 has a bottom plate 282 parallel to the overlap portion 30 and perpendicular to the inner edge of the bottom plate 282. The lap portion 30 is punched to form a buckle 284, and the lap portion 30 allows the buckle portion 28 of the adjacent fin 20 to be overlapped with the bottom plate 2 8 2 and the buckle portion 2 of the adjacent scale 20. 8 buckle ears 2 8 4 can pass over the side edges of the body 22 of the fin 20. When the above-mentioned plural fins 20 are stacked on each other, the buckle portion 2 8 of each fin 20 overlaps the overlap portion 30 of the adjacent fin 20 and the buckle 2 8 4 passes over it. After the side edges of the main body 22 can be bent and deformed to the inside of the fins 20 under the external force, they can be locked with the side edges of the main body 22 of the fins 20, so that the fins 20 cannot be easily separated from each other. At this time, the fins 20 and the folded edges 24 are combined to form a plane that can be closely adhered to the surface of the base 10. Understandably, the folds 24 and the overlapping portions 30 on the opposite sides of the fins 20 may be formed on both sides of the body 22 in opposite directions, respectively. It can also be understood that each of the above-mentioned fin 20 extensions 26 can be any other
