【新型所屬之技術領域】 本創作係有關於一種錐形基座之環形散熱器結構，尤 指一種可發揮較大散熱能力之散熱器結構。 【先前技術】 ^ 按’電腦產業逢勃發展，產品設計趨向輕薄短小，而 微處理器、晶片等電子元件之發熱量卻愈來愈高，使得散 熱成為維持產品系統正常運作的重要課題，而系統的散熱 方法’通常會以散熱片附於電子發熱元件表面，配合風扇 將熱排除於系統外，以防止元件過熱而燒毁及延長元件使 用壽命。一般所用的散熱器種類有平行式（如圓一）及圓環 式（如圖二），而其散熱片本身的製造方法有鋁擠型、壓鑄 型及堆疊型三種。 惟’平行式散熱器，三種製法都有使用，鋁擠或壓鑄 型散熱片之製造，因受限於機械加工能力，厚度無法做得 很薄’因此當數片散熱片组合起來的密度（單位體積之總 散熱面積）較低，而堆疊型可做得很較薄，其密度較高， 也就是其單位體積之總散熱面積較大，因此有較大的散熱 能力。 再者，圓環式目前只有使用鋁擠或壓鑄來製造散熱 片’而無採用摺疊型來製造。 由上可知，上述的散熱器結構，在散熱效率上可加以 改善。[Technical field to which the new type belongs] The present invention relates to a ring-shaped heat sink structure with a conical base, especially a heat sink structure that can exert a large heat dissipation capacity. [Previous technology] ^ According to the rapid development of the computer industry, product design tends to be thin and short, while the heat generation of electronic components such as microprocessors and chips is getting higher and higher, making heat dissipation an important issue to maintain the normal operation of product systems. The system's heat dissipation method is usually to attach a heat sink to the surface of the electronic heating element, and cooperate with the fan to exclude heat from the system to prevent the component from overheating and burn out and prolong the service life of the component. Generally, there are three types of radiators: parallel type (such as circle one) and ring type (see figure 2), and the manufacturing methods of the heat sink itself include aluminum extrusion type, die casting type, and stacked type. However, 'parallel heat sinks are used in all three manufacturing methods. The manufacture of aluminum extruded or die-cast heat sinks is limited by mechanical processing capabilities, and the thickness cannot be made very thin.' Therefore, the density of several heat sinks combined (unit The total heat dissipation area of the volume is lower, while the stacked type can be made thinner and its density is higher, that is, the total heat dissipation area per unit volume is larger, so it has greater heat dissipation capacity. Furthermore, the ring type is currently only manufactured by using aluminum extrusion or die-casting to manufacture the heat sink ', and not using the folding type. From the above, it can be seen that the above heat sink structure can be improved in heat radiation efficiency.
