Description

/ 1 / V. Creation Description (1) [Technical Field to which the New Type belongs] This creation is about ~ a kind of dispersive, stable structure and high heat dissipation efficiency σσ, especially a heat dissipation area with large size [previous technology] 隹 love fin Chip radiator. ，-With the continuous increase in the speed and speed of the electronic component running parts per unit volume, the electronic element infusion and die-casting radiator ς J increased by 2. Of course & ’Tradition is simple. Due to the limited heat dissipation requirements of this type of traditional heat sink, the temperature exchanged with the surrounding air is equal to force two, and its heat dissipation surface can actively and fully dissipate heat in a timely manner. The use of wind does not matter. It is true that the industry has improved the traditional radiators, and sought to increase the thermal area. As a result, a combined heat sink composed of a plurality of metal :: fins, such as the heat sink group shown in the first figure, forms a long folded edge 104 at each end of each of the two political heat sinks 102. When the heat sink is standing, the long folded edge 104 is formed on the heat sink base 106 by a thermal adhesive or welding method to form a stacked heat sink group, thereby increasing the overall heat dissipation area and making the heat sink have Higher heat dissipation capacity. However, using heat conductive glue or welding to attach the heat sinks 102 to the heat sink base one by one makes assembly extremely inconvenient and time-consuming; in addition, the heat sinks one by one are attached one by one. When it is placed on the heat sink base 106, the assembly effect is poor, which affects the heat transfer efficiency of the base and the heat sink, and the assembly cost is high, which is obviously not suitable for mass production. For this reason, some people in the industry have improved this kind of heat sink group and formed a heat sink assembly structure as shown in Figure 2. This structure has several heat sinks.

There are several opposite-shaped junctions on the fold 204. D < Dovetail notch 206 and Dowel joint 208, dovetail notch by adjacent heat sink 202? The combination of the burial burial hole Z U b and the tenon part 208 enables the fins 202 to be continuously tenoned in series. The nails are connected to form a heat sink body 210, and the heat sink body 210 is attached to the heat sink base 212. Although the heat sink assembly structure solves the shortcomings of the heat sink group shown in the first figure, the structure utilizes the mutual matching structure of the tenon gap 206 and the tenon joint 208 to connect the plurality of heat sinks 202 into one. In this way, during actual assembly and installation, the dowel joint notch 206 and the dowel joint 208 are easy to fall off; in addition, the folds 204 of the political heat plates 2 0 2 are set to be inclined outward, Therefore, it is inconvenient to make the heat sink set on the base 2 12, and it is more likely to cause the tenon gap 2 06 and the tenon portion 2 08 to fall off. Therefore, this structure needs to be improved. Therefore, how to provide a fin-stacked heat sink that not only has a large heat-dissipating area and is easy to assemble, but also that the combination between adjacent heat-dissipating fins is not easy to fall off, is a problem that the creative wants to solve. [Content] The purpose of this creation is to provide and provide a stacked fin heat sink that not only has a large heat dissipation area, is easy to assemble, but also has a stable structure. The stacked fin heat sink in this creation is composed of a base and a plurality of heat dissipation fins set on the base. Each cooling fin has a body. One end of the body forms a fold, and the other end is provided with two separate buckle ears. Cards are respectively provided on the hem and the outside of the buckle, and cards are provided at the interface with the body. There are fins at the other ends of the body, and the fins each protrude outwardly with a buckle. A notch is formed on the body corresponding to the buckle. Rear
