Description of the new model: [Technical field to which the new model belongs] The new model relates to a type of heat sink, especially a combined heat sink that can be installed to efficiently dissipate heat. [Previous technology] The central processing unit (CPU) in the host computer is also responsible for computing a large number of electronic signals. In order to effectively process astronomical and numerous data, the computing speed of the central processing unit can be said to be very amazing. In view of this, The highly-operating central processing unit generates great heat energy, and this energy must be taken away from the central processing unit immediately, otherwise the light will cause the operating efficiency to decrease, and the serious one will cause the central processing unit to stop operating and cannot be recovered. Therefore, in order to effectively remove the heat generated by the CPU, many devices and structures have been developed and used in practice. The most widely used # is the installation of many heat sinks on the top of the CPU, which are quickly absorbed through the heat sink. The characteristics of heat energy and conduction into the cooling air flow really solve the high temperature problem of the central processing unit. Referring to the two conventional heat sinks 1 and 1 shown in FIG. 1, for convenience of description, the structure of the heat sink 1 is described below as an example. The heat sink has a bottom plate 11, four side plates 12 (the two side plates 12 at the lower left in the figure are formed as a whole), four top convex plates 13, and four hook plates 14. Each of the side plates U extends outward from the peripheral edge of the bottom plate n, and defines a plurality of fastening spaces 15 between the bottom plate π and the side plate 12 in common with the bottom plate u. Each of the top convex plates 13 protrudes further outward from the side of each side plate 12 far from the bottom plate n. Each of the hook plates 14 is located at a position opposite to the side plate 12 from the outer peripheral edge of the bottom plate u, and M276256 extends toward the fastening space 15. With reference to FIG. 2, this kind of conventional knowledge is scattered, that is, the scattered piece (through the contour shown in multiple cutting procedures), it is necessary to cut a part of the material along the solid line shown in the figure. U, the side plate 12, the top convex plate 13, and the hook plate 14 are cut along the dotted line and then bent. Bend each side plate to form a vertical relationship between the two plates. In addition, in order to keep the shape flat and not bulged when two or two scattered w are docked up and down, the reserved space 16 is punched out from the outer wall surface of the top convex plate 13 inward. Referring to FIG. 3, when the two heat sinks ... 'are butted up and down, the heat dissipation is located at a relatively lower level; ^ "The top convex plate 13, which points to the fastening space of the heat sink relatively above, and presses the two heat sinks lightly ... , So that the top edge of the lower convex plate W is put into the fastening space 15 after being stressed, and cooperates with the reserved space 16 of the upper heat plate 1 to provide a buffer, so that the upper and lower sides of the scattered piece 1 ′ are flat and It is not convex, and the upper heat sink 14 holds the heat sink 丨 from the bottom and moves relative to each other. The sheet convex plate 13 restricts the heat sink fins such heat sinks Η, forming a gap between two, Provide a place for heat exchange with cold to promote the efficiency of heat energy removal. But the US and China Η hot film 系 is cut with the mother film as the substrate; the material of only a small part of the entire mother film material, but The cut materials accumulated over a long period of time and in large quantities are quite amazing. There is no needless expenditure in terms of capital. Therefore, most manufacturers choose to recycle, but they must pay additional personnel and recycling costs. Therefore, if the original heat sink design base Developed on the basis of M276256 Using the structural features of the heat sink itself, that is to achieve the purpose of multi-layer buckling to discharge heat, and to avoid waste caused by material cutting, should be the current trend. [New Content] Therefore, the purpose of this new model, That is to provide a combined heat sink that can be stacked and assembled without cutting off the material of the heat sink itself. Therefore, the new type of combined heat sink includes a bottom wall and two sides: the opposite sides of the bottom wall are in the same direction The extended side wall and a plurality of joint units. Each joint unit has a recess formed from each of the side walls, and a crotch portion protruding from the bottom wall opposite to the direction in which the side wall extends. Combined cymbals can be stacked two or two. , So that the plug-in part of one of the combined heat sinks is inserted into the projection of the other combined heat sink, and then the purpose of connecting by @ 定 is achieved. [Embodiment] Regarding this new one, the other technical content, characteristics and The effect will be clearly shown in the following detailed description of a preferred embodiment with reference to the drawings. F Before the present invention is described in detail, it should be noted that in the following, The similar elements in the inner valley are indicated by the same numbers. Referring to FIG. 4 and FIG. 5, the preferred embodiment of the novel combined heat sink 2 is made of copper metal, and is capable of moving at a high speed. e is on the top of a central processing unit 3 (shown in Figure 8), which is used to dissipate the heat energy generated by the central lukou and virgin 3 to reduce its operating temperature. The following is the heat sink 2, The type, type a, and government heat fins 2 are used as an example to explain the structure, but the combination 2 is actually the same structure. The combined heat sink 2 includes a M276256 long rectangular bottom wall 21, two side walls 22, 24, and four bonding units. 23. Among them, each of the side walls 22 and 24 extends perpendicularly from the two long side edges of the bottom wall 21 in the same direction as the bottom wall 21. All joint units 23 are adjacent to the side walls 22 and 24 in pairs, and Each engaging unit 23 has an inserting groove 231, a lower abutting section 232, and a connecting portion 233. The cover groove 23 1 is formed by recessing from the outer wall surface of each side wall 22 or 24 toward the other side wall 24 or 22. The lower abutment section 232 is formed at a position of the side wall 22 or 24 relative to the inlay groove 231, and protrudes obliquely from the side wall 22 or 24 toward the other side wall 24 or 22. The abutment section 232 in this embodiment is Formed by stamping the side walls 22, 24, the δ stamping element is pressed to fold out the lower abutment section 232, so that the lower abutment section 232 is obliquely deformed toward the other side wall 22 or 24 thereof. In addition, when the lower abutment section 232 is folded out from the side wall 22 or 24, a retaining opening 236 is defined. The plug-in portion 233 protrudes from the bottom wall 21 toward the opposite side walls 22, 24. Each of the plug-in portions 233 includes an extension section 234 and an upper abutment section 235. The plug-in section 233 is stamped on the bottom wall 21, and the upper abutment section 235 and the extension section 234 are also in the plug-in section 233. Defined by stamping. The upper abutting section 235 extends obliquely after being folded from the extension section 234 in the direction of the other side wall 22 or 24. Referring to FIG. 5 and FIG. 6 at the same time, in this embodiment, two combined heat sinks 2 and 2 ′ are used as examples to describe a case where a plurality of combined heat sinks 2 and 2 are stacked, but the combined type used in actual use The number of heat sinks is not a feature of the novel model, nor is it limited by this embodiment. The plug-in part 233 of the combined heat sink 2 located on the left side of FIG. 5 faces M276256 toward the combined heat-sink M 2 ', so that the plug-in part 233 can extend into the corresponding recess 231' because the horse is far up and down The abutting sections 235 and 232 are bent and protruded in the direction of the other side wall 22 or 24, so the lower abutting section 232 is to hold the upper abutting section 235 from below the upper abutting section, and the two are based on the appearance Reciprocal cooperation has formed a restrictive relationship. Furthermore, since the lower abutment section 232 'is folded out from the side wall 22 or 24, the | soil 2 forms a clamping opening 236', so when the plug-in portion 233 projects into the recess 231, the upper and lower abutments The contact sections 235 and 232 are pressed against each other. The upper contact section 235 restricts the top edge of the upper contact section into the clamping port 236, and the sliding displacement of the input 235 is taken out. Referring to FIG. 4 and FIG. 7 at the same time, in addition to forming the insert groove 231 and the plug-in portion 233 through multiple stampings on the heat sink 2, the present invention forms a lower abutment section 232 on the sides J 22 and 24, respectively, and The extended section 234 and the upper abutment section 235 on the plug portion 233, that is, the components on the heat sink 2 are not formed by cutting the heat sink 2 'or welding supplementary material afterwards, and the heat sink M 2 itself is fully applied. The available materials, without a half increase or decrease, can be called the maximum use efficiency, to avoid cutting the material in order to form a specific structure, which will cause a wave of raw material costs, and manufacturers will not have to worry about recycling the cutting materials, which also simplifies the work. aging. In addition, the new type uses the upper and lower abutment sections 235 and 232 to stack and abut against each other, which has the effect of local limit. The top edge of the upper abutment & 235 is embedded into the card opening 236, which greatly limits the upper abutment. The displacement or sliding of the contact section 235 directly restricts the upper contact section 235 from being locked only by the lower contact section 232, unless an external force sufficient to overcome the pull-out of the lower contact section 232 and the stop 236 is provided. Only M276256 can separate the combined heat sinks 2 and 2. It must be noted that this embodiment is based on the example that each of the combined heat sinks 2 has two side walls 22, 24 and four bonding units 23, which is flexible and not limited to this embodiment. Definer, in other words, pick. The number of single 7L 23 is based on the premise of achieving balance, which should still fall within the scope of this new variant. As shown in FIG. 8, when a plurality of combined heat sinks 2 are used to install the central container 3, all the combined heat sinks 2 are arranged in such a manner that the side wall μ is closely attached to the top surface of the central processing H 3. Another air channel is formed between the two combined heat sinks 2. The side wall 24 directly contacts the central processing unit 3 and takes the energy away from the central processing unit 3, and is finally carried away by the circulating airflow of the air duct. After comparing with the conventional technology, it can be known that one of the multiple combined heat sinks 2 is stacked on one side of the & side J 22 or 24 and is closely attached to the top surface of the CPU 3, and the number of the combined heat sinks 2 can be changed with With the flexible adjustment of the size of the central processing H 3, SUb 'When the number of stacked heat sinks 2 is increased, the number of air ducts that can be formed is larger, so compared to the conventional technology, the new type of combined heat sink 2 Provides more significant heat transfer efficiency. On the other hand, the arrangement of the combined heat sink 2 is not limited to central processing. Those who require the heat sink to provide auxiliary heat dissipation effects in the same sample, such as a condenser tube or condenser, can also choose to use the new combined heat sinks 2, 2. And, as mentioned above, the side walls 22 or 24 of the combined heat sinks 2, 2 can be flexibly adjusted according to different setting positions, which has a high versatility value. The new combined heat sinks 2, 2 'can be slightly changed in the first embodiment for the design origin. That is, each of the embedded grooves 231, 231 is changed to be within the side walls 22, 24. 10 M276256 The wall surface is changed to be recessed away from the other side walls 24, 22, and cooperates with the recessed directions of the embedded grooves 231, 231 '. The abutting sections 235, 232, and 232 also protrude away from the other side walls 24 and 22, and the top edge of the upper abutting section 235 is inserted into the clamping opening 236, so that this embodiment can also use up and down abutments. This method can achieve the effect of restraint. To sum up, the new type of combined heat sinks 2 and 2 use stamping to replace the traditional molding method of cutting partial materials in the molding process, and rely on the upper and lower abutment sections 235, 232, and 232 to press each other against the limit position. In conjunction with the card openings 236 and 236, it is limited to the arbitrary displacement of pure 235, making full use of the structure of the combined heat sinks 2 and 2 'without the need to cut materials to cause waste, which can be stacked in layers for most combined heat sinks. Films 2, 2 really do something new.
