另外，如圖3與圖4所示，在本實施例中，各第一韓片ιΐ6更可具有二個缺口 116a、肠，，用以與第二散_片組m接合。舉例而言，缺口 116a遠離於繼114,且其位置對應於扣環既，而缺口腕，則鄰近於麵114的-外表面ma，且其位置對應於扣環122^,。因此，第二鰭片122互相扣合以組合成第二散熱則組12()之後，第二散熱縛片組120可透過互相扣合的扣環122c，承靠於外表面ma。接著，扣、環122c、122c，可分別穿設於對應的缺口 116a、ma，中，以使第二散熱籍片組120與第一散熱鰭片組110互相接合。然後，使用者可再將^ 少部分的扣環122c，焊接接合於側壁114的外表面ma，以組式散熱模纟JL1GG。值得注意的是，在本實施例中，第一散熱鰭片組11〇的材質例如是鋁，而第二散熱鰭片組120的材質例如是鋼。因此，第一散熱鰭片組110的―第—導熱係數會小於第二散熱鰭版12G的-第二導熱係數。另外，第一散熱鰭片組110可藉由目前常見用來製作鋁製散熱鰭片組的擠出成型方式-體成型製成，以使其可具有較低的製作成本，而第二散熱鰭片組120則可藉由沖壓成型方式先製作出多個第二鰭片 122，然後再互相扣合這些第二鰭片丨22而製成，以使其可具有較高的散熱效率。基於上述，相較於先前技術中完全以擠出成型方式所製成的鋁製散熱鰭片組來說，本實施例的複合式散熱模組1〇〇可具有較佳的散熱效率。另外，相較於先前技術中完全以沖壓成型方式所製成的銅製散熱鰭片組來說，本實施例的複合式散熱模組1〇〇則可具有較低的製作成本。換句話說，本實施例的複合式散熱模組1〇〇不但會具有較低的製作成本，並且可維持一定的散熱效率。 M364818 认士it之外如圖1與圖4所不’在本實施例卜各個第—鰭片⑽ \忠可具有—個分岔腿，以使複合式散熱模組_可藉由分岔 m姻面積，進而提升散熱鱗。另外，在其他杨示的實，《嫩式散熱模組此外，熱源適於容置於容置空間U0a中，並承靠於底板m，以藉由複合式餘歡则進行絲。為了讓所屬胁魏巾具有通常知識者可㈣雜縣創制麻_轉以實施，以下將舉出更多Further, as shown in Fig. 3 and Fig. 4, in the present embodiment, each of the first Korean sheets ι 6 may further have two notches 116a and an intestine for engaging with the second sheet group m. For example, the notch 116a is spaced away from the subsequent 114 and its position corresponds to the buckle, while the notched wrist is adjacent to the outer surface ma of the face 114 and its position corresponds to the buckle 122. Therefore, after the second fins 122 are fastened to each other to be combined into the second heat dissipation group 12(), the second heat dissipation tab group 120 can bear against the outer surface ma through the mutually fastened buckles 122c. Then, the buckles, the rings 122c and 122c are respectively disposed in the corresponding notches 116a, ma, so that the second heat-dissipating chip group 120 and the first heat-dissipating fin group 110 are joined to each other. Then, the user can weld a small portion of the buckle 122c to the outer surface ma of the side wall 114 to form a heat dissipation mold JL1GG. It should be noted that, in this embodiment, the material of the first heat radiation fin group 11 is, for example, aluminum, and the material of the second heat radiation fin group 120 is, for example, steel. Therefore, the first thermal conductivity of the first heat dissipation fin group 110 is smaller than the second thermal conductivity of the second heat dissipation fin plate 12G. In addition, the first heat dissipation fin group 110 can be formed by an extrusion molding method which is commonly used to fabricate aluminum heat dissipation fin sets, so that it can have a low manufacturing cost, and the second heat dissipation fin The chip set 120 can be formed by first forming a plurality of second fins 122 by stamping, and then fastening the second fins 22 to each other so that the heat dissipation efficiency can be improved. Based on the above, the composite heat dissipation module 1 of the present embodiment can have better heat dissipation efficiency than the aluminum heat dissipation fin set which is completely formed by extrusion molding in the prior art. In addition, the composite heat dissipating module 1 of the present embodiment can have a lower manufacturing cost than the copper heat dissipating fin set which is completely formed by the press forming method in the prior art. In other words, the composite heat dissipation module 1 of the present embodiment not only has a low manufacturing cost, but also maintains a certain heat dissipation efficiency.
