Description

散熱單元及其散熱模組Cooling unit and cooling module
本發明是有關於一種散熱單元及其散熱模組,尤指一種可大幅強化散熱鰭片之結構強度並減少生產成本之散熱單元及其散熱模組。The invention relates to a heat dissipation unit and a heat dissipation module thereof, in particular to a heat dissipation unit and a heat dissipation module which can greatly strengthen the structural strength of the heat dissipation fins and reduce the production cost.
按,由於科技時代的進步,電子元件之運作效能越來越高,以至於對散熱器的功能要求也隨之增加,習知之散熱器為了能增加散熱功效,都已大幅採用堆疊式的散熱鰭片組,而不斷於散熱鰭片上研發改良,因此高效能之散熱器已經是今天產業界最重要的研發重點之一。 以電腦主機為例,其內部中央處理單元(CPU)所產生之熱量佔大部分,此外,中央處理單元當熱量逐漸升高會造成執行效能降低,且當熱量累積高於其容許限度時,將會迫使電腦當機,嚴重者更可能會造成毀損現象;並且,為解決電磁波輻射之問題,通常係以機箱殼體來封閉該電腦主機,以致如何將中央處理單元及其它發熱零組件(或稱元件)之熱能快速導出,成為一重要課題。 請參閱第1圖係為習知散熱單元之立體圖,於傳統之散熱鰭片設計中,其散熱鰭片組1主要係經由複數散熱鰭片11扣接組成,該散熱鰭片11係由薄金屬板沖壓而成,且頂緣近兩端處彎折延伸一折邊111,並於該折邊111上設有一扣端1112及一扣部1111,當該散熱鰭片11與另一散熱鰭片11作堆疊組合時,藉由位於前端之散熱鰭片11所設之折邊111與位於後端之散熱鰭片11之平面112接觸並抵頂於平面112上,令位於前端散熱鰭片11之扣端1112勾扣於後端散熱鰭片11之扣部1111使散熱鰭片11與另一散熱鰭片11結合,但由於複數散熱鰭片11於彼此堆疊扣合時並無實際支撐力量,且因其散熱鰭片11係由薄金屬板沖壓切割而成,其散熱鰭片11會因過薄而產生強度不足經常易因擠壓的力道受力不均而造成散熱鰭片11之結構強度受到破壞產生彎折、扭曲或其他之變形現象。 以上所述,習知具有下列之缺點: 1.無法承受較大的擠壓; 2.造成變形問題。 是以,要如何解決上述習用之問題與缺失,即為本案之發明人與從事此行業之相關廠商所亟欲研究改善之方向所在者。According to the advancement of the technology age, the operating efficiency of electronic components is getting higher and higher, so that the functional requirements of the heat sink are also increasing. The conventional heat sinks have greatly adopted stacked cooling fins in order to increase the heat dissipation efficiency. Chip group, and continue to develop and improve on the cooling fins, so high-efficiency heat sinks have become one of the most important research and development priorities in the industry today. Take the host computer as an example. The internal central processing unit (CPU) generates most of the heat. In addition, when the central processing unit gradually increases in heat, it will reduce the performance of the execution, and when the heat accumulation is higher than its allowable limit, it will It will force the computer to crash, and in severe cases, it may cause damage; moreover, in order to solve the problem of electromagnetic wave radiation, the computer host is usually closed with a chassis shell, so how to centrally process the unit and other heat-generating components (or called The rapid extraction of thermal energy from components) has become an important issue. Please refer to FIG. 1 for a perspective view of a conventional heat dissipation unit. In a conventional heat sink fin design, the heat sink fin group 1 is mainly composed of a plurality of heat sink fins 11 which are made of thin metal. The plate is stamped, and a folded edge 111 is bent and extended near the two ends of the top edge, and a buckled end 1112 and a buckled portion 1111 are provided on the folded edge 111. When the heat dissipation fin 11 and another heat dissipation fin When 11 is used as a stack combination, the fold 111 provided on the front-side heat-dissipating fin 11 is in contact with the flat surface 112 of the heat-dissipating fin 11 on the back-end and abuts on the plane 112, so that the The buckling end 1112 is hooked on the buckling part 1111 of the rear heat dissipation fin 11 to combine the heat dissipation fin 11 with another heat dissipation fin 11, but since the plurality of heat dissipation fins 11 are stacked and fastened to each other, there is no actual support force, and Because the heat dissipation fins 11 are stamped and cut from a thin metal plate, the heat dissipation fins 11 are too thin and have insufficient strength. Often, the structural strength of the heat dissipation fins 11 is easily affected by the uneven force of the pressing force. Destruction causes bending, distortion or other deformation. As mentioned above, the conventional method has the following disadvantages: 1. It cannot withstand large compression; 2. It causes deformation problems. Therefore, how to solve the above-mentioned problems and shortcomings of the custom, that is, where the inventor of this case and the relevant manufacturers engaged in this industry are eager to study and improve.
