New Description: [New Technology Field] This paper is about a heat sink with a snap-fit structure and its combined structure, especially a snap-fit improvement that makes the snap stronger and elastically changeable. The structure of the heat sink and its combined structure. [Prior Art]
於目前電子裝置中，對於許多發熱源（例如晶 片、中央處理器、發光二極體燈源等）皆會組設有所 謂之散熱裝置，且散熱裝置具有多種形式，例如散 熱鰭片、熱管、散熱風扇等。 目前有一種散熱裝置是以複數片散熱片所相連 接合排列而成，因此，每一散熱片之間的卡扣結構 則成為組合後之散熱片是否能夠穩固之重要因素。 請參閱圖1，其係為習知散熱片組合結構之立體 圖，由圖式可知，傳統散熱片組合結構9係藉由卡 扣結構91將複數片散熱片90彼此相連接合排列， 而每一卡扣結構91包括一折片911及一凸緣912, 且凸緣912具有一卡合孔913，當組合時，前一散熱 片90之卡合孔913係嵌合於後一散熱片90之凸緣 912。 然而，此種卡扣結構9 1之凸緣9 1 2與卡合孔9 1 3 係彼此卡死，換言之，整體散熱片組合結構9並無 法彈性變化，例如因吸熱散熱而熱漲冷縮時，上述 傳統之散熱片組合結構9則無法因應此種使用上之 彈性變化，仍非十分理想。 3 M392534In the current electronic device, a plurality of heat sources (such as a wafer, a central processing unit, a light source, and the like) are provided with a so-called heat sink, and the heat sink has various forms, such as heat sink fins and heat pipes. Cooling fan, etc. At present, there is a heat dissipating device which is formed by a plurality of fins connected and connected. Therefore, the snap structure between each fins is an important factor for whether or not the combined fins can be stabilized. Please refer to FIG. 1 , which is a perspective view of a conventional heat sink assembly structure. As shown in the drawings, the conventional heat sink assembly 9 is configured by the snap structure 91 to connect a plurality of heat sinks 90 to each other, and each card is arranged. The buckle structure 91 includes a flap 911 and a flange 912, and the flange 912 has an engaging hole 913. When assembled, the engaging hole 913 of the front heat sink 90 is fitted to the convex portion of the rear heat sink 90. Edge 912. However, the flange 9 1 2 of the buckle structure 9 1 and the engaging hole 9 1 3 are stuck to each other. In other words, the integral fin assembly 9 cannot be elastically changed, for example, due to heat absorption and heat dissipation. The conventional heat sink assembly structure 9 described above cannot be adapted to the elasticity of the use, and is still not very satisfactory. 3 M392534

Thereby, the engagement between the heat sinks can be more firm, and the card holes have a specific shape, such as a circular arc shape, so when the plurality of heat sinks are buckled, the heat sinks can have a relatively large rotation angle. The change between the heat sinks is caused by, for example, heat expansion and contraction. In addition, when a plurality of heat sinks having the above structure are fastened to each other, the flaps of the previous heat sink are embedded in the card holes of the latter heat sink and are spaced apart from the rear tabs of the heat sink, a previous piece The hook is correspondingly connected to the spring piece of the rear heat sink, thereby forming a heat sink combined structure. In the case of the above-mentioned heat sink combination structure, in the case of the expansion and contraction caused by heat absorption and heat dissipation, the heat sink is combined with the design of the gap between the front heat sink and the latter one. Each of the fins has an effect of varying the elasticity of the pitch, and the number of the fins can thus be increased or decreased as needed to form a patch combination structure.
