Description

散热鳍片与底座的组合结构
技术领域
本实用新型系提供一种散热鳍片与底座的组合结构设计，其系在各散热鳍片底端预设呈相互交错的弯折部及翼钩部，以配合浇注或挤压方式而使散热鳍片可快速稳固的结合于散热底座沟槽。 
背景技术
习知散热器，主要系包括底座与复数个散热鳍片所组成，或亦可在底座嵌入结合一个以上的热导管，针对底座与散热鳍片的结合，除了传统的焊接结合技术以外，亦有如美国第5014776号实用新型专利案，系将散热鳍片预先插植于底座沟槽，再通过冲压方式使各散热鳍片被夹持结合于底座沟槽，以达到散热鳍片与底座的结合目的。 
上述先前专利技术，主要是于散热鳍片底端预先形成一水滴形、锥形或圆形的较大凸部，而底座沟槽的开口是呈上大下小，因此散热鳍片只能从底座沟槽的侧面方向插入，再进行冲压夹持，以完成结合，此项设计，由于无法采用垂直方向直接插入底座沟槽，因此于组装施实时将会相当的复杂不便。 
或如美国第6758262号实用新型专利案，虽系采用垂直方向将散热鳍片直接插入底座沟槽，但只能利用底座沟槽两侧的挤压变形而达到夹持目的，夹持作用力都集中在沟槽开口两侧的变形位置，仅具有两个点状的夹持力，因此，夹持效果不佳，无法发挥稳定结合的作用，各散热鳍片很容易发生参差不齐的不等高现象，且会发生摇动甚至脱落情形。此外，亦有人预先将散热鳍片的底端形成一反折部，或是形成一L形弯折部，再插入底座沟槽，以供冲压结合，但还是无法解决各散热鳍片于结合后可能发生侧倾偏斜的情形。 
实用新型内容
本实用新型之主要目的，乃在于提供一种散热鳍片与底座的组合结构设计，其系至少包括一底座及复数个散热鳍片，该散热底座系开设可供复数个散热鳍片对应插植的沟槽，其特别在各散热鳍片底端冲压形成相互交错的复数个弯折部，使散热鳍片的底端可匹配插入散热底座的沟槽，利用相互交错方向的弯折部，可于沟槽内形成稳定站立，故不会发生侧倾偏斜，再通过浇注或挤压方式，将散热鳍片的底端埋设结合或紧迫夹持于沟槽内，利用底端相互交错的弯折部可包裹埋置或夹持卡止于散热底座沟槽，以达到稳固定位结合，确保散热鳍片与底座的组合非常平整稳定，不会发生参差不齐的不等高现象，更不会发生摇动或脱落情形。 
本实用新型之次要目的，乃在于提供一种散热鳍片与底座的组合结构设计，其系可在交错分布的弯折部之间，再增设相互交错方向的复数个翼钩部，各翼钩部系呈斜向倒钩状，因此于通过浇注或挤压后，可在散热底座沟槽内形成逆向钩持的包裹埋置或夹持卡止，以确保其结合更为稳固。 
为实现上述目的，本发明采用如下之技术方案： 
一种散热鳍片与底座的组合结构，其系至少包括一底座及复数个散热鳍片，该散热底座并开设可供复数个散热鳍片对应插植的沟槽，而其特征在于：所述各散热鳍片系于底端冲压形成相互交错方向的复数个弯折部，利用交错分布的弯折部对应插入沟槽形成稳定站立，而通过浇注或挤压方式，将各散热鳍片的底端埋设结合或紧迫夹持于沟槽内。
作为一种优选方案，各散热鳍片的弯折部系沿散热鳍片的底端伸出而分别交错设置于散热鳍片的两侧。 
作为一种优选方案，该散热鳍片的弯折部，系实施为一呈L形的弯折部，并具有一伸出段。 
作为一种优选方案，该伸出段的底面均位于同一平面上。 
作为一种优选方案，该散热鳍片系在交错分布的弯折部之间，设有相互交错方向的复数个翼钩部。 
作为一种优选方案，各翼钩部系呈斜向倒钩状。 
作为一种优选方案，该散热鳍片系在同一高度上开设复数个冲压开口，使各翼钩部系沿着冲压开口的底端形成斜向往上伸出的翼钩形状。 
作为一种优选方案，系将液态铝金属充填于散热底座的沟槽，而于固化后形成包埋结合。 
作为一种优选方案，该底座沟槽的两侧壁系下压变形而紧迫夹持于散热鳍片底端。 
作为一种优选方案，该底座系紧配结合一个以上的热导管。

具体实施方式
下面结合附图与具体实施方式对本实用新型作进一步描述。 
如图1所示，本实用新型所为一种散热鳍片与底座的组合结构设计，其系至少包括一底座1及复数个散热鳍片2，该散热底座1并开设可供复数个散热鳍片2对应插植的沟槽11，所述各散热鳍片2系于底端冲压形成相互交错方向的复数个弯折部21（如图2至图4所示），并利用交错的弯折部21，可对应插入沟槽11而形成稳定站立（如图5），进而通过浇注或挤压方式，将所述各散热鳍片2的底端埋设结合（如图6）或紧迫夹持（如图7）于沟槽11内，以达到稳固的定位结合，确保散热鳍片2与散热底座1的组合非常平整稳定，使散热鳍片2不会发生侧倾偏斜或参差不等高的现象，更不会摇动或脱落。 
如上述各散热鳍片2的弯折部21，其系可沿散热鳍片2的底端伸出而分别交错设置于散热鳍片2的两侧，上述散热鳍片2的弯折部21，系可实施为如图所示的L形的弯折部21（但并不以L形为限），并可具有一伸出段211，使各伸出段211的底面均位于同一平面上；由于散热鳍片2底端两侧均同时具有相互交错方向的复数个弯折部21，因此各散热鳍片2插入底座1的沟槽11时，各散热鳍片2即可利用两侧交错的复数个弯折部21而稳定站立于沟槽11内。 
如上述图1至图7的实施例显示，其系可在交错分布的弯折部21之间，再增设相互交错方向的复数个翼钩部22，而各翼钩部22系呈斜向倒钩状。因此于通过浇注或挤压后，可进一步在散热底座沟槽11内形成逆向的包裹埋置或夹持卡止，以确保其结合更为稳固。 
上述的散热鳍片2，其系在同一高度上开设复数个冲压开口221，并使各翼钩部22系沿着冲压开口221的底端形成斜向往上伸出的翼钩形状，而于通过浇注或挤压后，在散热底座沟槽11内形成逆向的包裹埋置或夹持卡止。 
依上述本实用新型所使用的浇注方式，其系适合使用液态铝金属，并配合相对的成型模具，将液态铝金属倒入成型模具中，使其可充填于散热底座1的沟槽11，于固化后即可将散热鳍片2底端的弯折部21及翼钩部22均包埋结合（如图6）。 
而本实用新型所使用的挤压方式，其系使用冲压设备的冲压冲头，对准散热鳍片2的插植部位进行冲压，使沟槽11两侧壁产生下压变形，进而可紧迫夹持于散热鳍片2底端的弯折部21及翼钩部22（如图7）。 
如图8至图13所示，本实用新型所设的底座1，进一步亦可结合一个以上的热导管3而形成紧配嵌合，用以组成一附有热导管3的散热器，其主要系在本实用新型底座1的另一端面开设一个以上可适配嵌入热导管3的嵌槽，并于紧配嵌合后，使热导管3外露于底座1底面，且具有平整露出的贴底面31。 
上述实施例中，所述一个以上的热导管3，其系可呈平行并列的形态而紧配嵌合于本实用新型的底座1（如图8），或所述一个以上的热导管3，亦可呈S形或其它选定形状的并列形态而紧配嵌合于本实用新型的底座1（如图10至图13）；又，所述一个以上的热导管3，其并列时亦可实施为具有相离间隙（如图8、图10或图12所示），或是不具有相离间隙的无缝接合构造（如图9、图11或图13所示），其中的第十一图实施例，主要是指在与发热组件（如CPU等）的贴触部位，使一个以上的热导管3形成无缝接合构造。 
以上所述，仅是本实用新型结构较佳实施例而已，并非对本实用新型的技术范围作任何限制，故凡是依据本实用新型的技术实质对以上实施例所作的任何细微修改、等同变化与修饰，均仍属于本实用新型技术方案的范围内。
