Description

散熱鰭片與底座的組合結構 Combined structure of heat sink fin and base

本發明係提供一種散熱鰭片與底座的組合結構設計，其係在各散熱鰭片底端預設呈相互交錯的彎折部及翼鉤部，以配合澆注或擠壓方式而使散熱鰭片可快速穩固的結合於散熱底座溝槽。 The invention provides a combined structural design of a heat dissipating fin and a base, which are preset at the bottom ends of the heat dissipating fins with mutually staggered bent portions and wing hook portions to match the pouring or pressing manner to the heat dissipating fins. Quickly and firmly bonded to the heat sink groove.

習知散熱器，主要係包括底座與複數個散熱鰭片所組成，或亦可在底座嵌入結合一個以上的熱導管，針對底座與散熱鰭片的結合，除了傳統的焊接結合技術以外，亦有如美國第5014776號發明專利案，係將散熱鰭片預先插植於底座溝槽，再通過沖壓方式使各散熱鰭片被夾持結合於底座溝槽，以達到散熱鰭片與底座的結合目的。 The conventional heat sink mainly consists of a base and a plurality of heat radiating fins, or may be embedded with more than one heat pipe in the base. For the combination of the base and the heat sink fins, in addition to the traditional welding and bonding technology, In the invention patent No. 5014776, the heat dissipation fins are pre-planted in the groove of the base, and then the heat dissipation fins are clamped and bonded to the groove of the base by punching to achieve the purpose of combining the heat dissipation fins with the base.

上述先前專利技術，主要是於散熱鰭片底端預先形成一水滴形、錐形或圓形的較大凸部，而底座溝槽的開口是呈上大下小，因此散熱鰭片只能從底座溝槽的側面方向插入，再進行沖壓夾持，以完成結合，此項設計，由於無法採用垂直方向直接插入底座溝槽，因此於組裝施實時將會相當的複雜不便。 The above prior patent technology mainly pre-forms a large convex portion of a teardrop shape, a cone shape or a circular shape at the bottom end of the heat dissipation fin, and the opening of the base groove is upper and lower, so the heat dissipation fin can only be The side of the groove of the base is inserted in the direction of the groove, and then punched and clamped to complete the joint. This design, since it cannot be directly inserted into the groove of the base in the vertical direction, it is quite complicated and inconvenient to assemble in real time.

或如美國第6758262號發明專利案，雖係採用垂直方向將散熱鰭片直接插入底座溝槽，但只能利用底座溝槽兩側的擠壓變形而達到夾持目的，夾持作用力都集中在溝槽開口兩側的變形位置，僅具有兩個點狀的夾持力，因此，夾持效果不佳，無法發揮穩定結合的作用，各散熱鰭片很容 易發生參差不齊的不等高現象，且會發生搖動甚至脫落情形。此外，亦有人預先將散熱鰭片的底端形成一反折部，或是形成一L形彎折部，再插入底座溝槽，以供沖壓結合，但還是無法解決各散熱鰭片於結合後可能發生側傾偏斜的情形。 Or, as in the US Patent No. 6,752,262, although the heat sink fins are directly inserted into the base groove in the vertical direction, the crushing deformation on both sides of the base groove can be used to achieve the clamping purpose, and the clamping force is concentrated. In the deformation position on both sides of the groove opening, there are only two point-like clamping forces, so the clamping effect is not good, and the stable bonding effect cannot be exerted, and the heat dissipation fins are very accommodating. It is prone to uneven unequal heights, and it may cause shaking or even falling off. In addition, some people have previously formed a reflexed portion at the bottom end of the heat dissipating fin, or formed an L-shaped bent portion, and then inserted into the groove of the base for punching and bonding, but still cannot solve the problem that the heat dissipating fins are combined. A situation in which the roll skew may occur.

本發明之主要目的，乃在於提供一種散熱鰭片與底座的組合結構設計，其係至少包括一底座及複數個散熱鰭片，該散熱底座係開設可供複數個散熱鰭片對應插植的溝槽，其特別在各散熱鰭片底端沖壓形成相互交錯的複數個彎折部，使散熱鰭片的底端可匹配插入散熱底座的溝槽，利用相互交錯方向的彎折部，可於溝槽內形成穩定站立，故不會發生側傾偏斜，再通過澆注或擠壓方式，將散熱鰭片的底端埋設結合或緊迫夾持於溝槽內，利用底端相互交錯的彎折部可包裹埋置或夾持卡止於散熱底座溝槽，以達到穩固定位結合，確保散熱鰭片與底座的組合非常平整穩定，不會發生參差不齊的不等高現象，更不會發生搖動或脫落情形。 The main purpose of the present invention is to provide a combined structure design of a heat dissipating fin and a base, which includes at least a base and a plurality of heat dissipating fins, and the heat dissipating base is provided with a groove for inserting a plurality of fins corresponding to the fins. The groove is formed by punching a plurality of bent portions at the bottom end of each of the heat dissipation fins so that the bottom end of the heat dissipation fin can be matched with the groove of the heat dissipation base, and the bent portion of the mutually staggered direction can be used for the groove The stable standing in the groove is formed, so that the roll deflection does not occur, and the bottom end of the heat dissipation fin is buried or tightly clamped in the groove by pouring or pressing, and the bent portions which are staggered at the bottom end are used. It can be wrapped or clamped to the groove of the heat dissipation base to achieve stable and fixed position combination, ensuring that the combination of the heat dissipation fin and the base is very smooth and stable, and there is no uneven phenomenon of unevenness, and no shaking occurs. Or shedding.

本發明之次要目的，乃在於提供一種散熱鰭片與底座的組合結構設計，其係可在交錯分佈的彎折部之間，再增設相互交錯方向的複數個翼鉤部，各翼鉤部係呈斜向倒鉤狀，因此於通過澆注或擠壓後，可在散熱底座溝槽內形成逆向鉤持的包裹埋置或夾持卡止，以確保其結合更為穩固。 A second object of the present invention is to provide a combined structure design of a heat dissipating fin and a base, which can add a plurality of wing hook portions in a staggered direction between the staggered bent portions, and each wing hook portion The utility model has an oblique barb shape, so that after casting or squeezing, a reverse-hook package embedding or clamping can be formed in the groove of the heat dissipation base to ensure that the bonding is more stable.
