Description

散热鳍片及散热装置 技术领域
本发明涉及一种散热鳍片及散热装置, 尤指一种可在制造散热装置的过程 中防止溢料并且与基座紧密结合的散热鳍片。 背景技术
散热装置与电子产品的发展息息相关。 由于电子产品在运作时, 电路中的 电流会因阻抗的影响而产生不必要的热能, 如果这些热能不能有效地排除而累 积在电子产品内部的电子元件上, 电子元件便有可能因为不断升高的温度而损 坏。 因此, 散热装置的优劣影响电子产品的运作甚巨。
请参阅图 1, 图 1为现有技术的圆柱型散热鳍片 12的示意图。 一般而言, 散热装置上设置有图 1所示的圓柱型散热鳍片 12。 如图 1所示, 圓柱型散热鳍 片 12是由压铸制作过程与基座 10—体成型。由于压铸制作过程中的脱模需求, 圆柱型散热鳍片 12需要有二至三度的脱模角 α, 所以整体重量较重, 且鳍片高 度会受到限制。 此外, 在相同大小的散热装置中, 脱模角 α会使得鳍片数量较 少, 造成散热面积不足, 散热性能较差。 发明内容
本发明提供一种可在制造散热装置的过程中防止溢料并且与基座紧密结合 的散热鳍片。 该散热鳍片以成型制作过程加以成型, 可不需现有散热鳍片的脱 模角。
根据一实施例, 本发明的散热鳍片包含一散热部、 一固定部以及一防溢料 结构。 固定部的表面形成有一咬合结构。 防溢料结构连接于散热部与固定部之 间。 防溢料结构的宽度大于散热部的宽度。
所述的散热鳍片, 其中, 该咬合结构为一螺紋、一斜纹、 一网紋或一直纹。 所述的散热鳍片, 其中, 更包含一四槽结构, 形成于该固定部上。
所述的散热鳍片, 其中, 该防溢料结构的宽度大于该固定部的宽度。
所述的散热鳍片, 其中, 该防溢料结构自该固定部向外突出的长度介于 1 毫米与 10毫米之间。 所述的散热鳍片, 其中, 该防溢料结构为等厚度。
所述的散热鳍片, 其中, 每一个散热鳍片为一圓柱型散热鳍片。
根据另一实施例, 本发明的散热装置包含一基座以及多个散热鳍片。 每一 个散热鳍片包含一散热部、一固定部以及一防溢料结构。 固定部固定于基座中, 且固定部的表面形成有一咬合结构。 防溢料结构连接于散热部与固定部之间。 防溢料结构的宽度大于散热部的宽度。
所述的散热装置, 其中, 该咬合结构为一螺紋、一斜纹、 一网紋或一直纹。 所述的散热鳍片, 其中, 每一该等散热鳍片更包含一凹槽结构, 形成于该 固定部上。
所述的散热鳍片, 其中, 该防溢料结构的宽度大于该固定部的宽度。
所述的防溢料结构自该固定部向外突出的长度介于 1毫米与 10毫米之间。 所述的散热鳍片, 其中, 该防溢料结构为等厚度。
所述的散热鳍片, 其中, 每一个散热鳍片为一圆柱型散热鳍片。
所述的散热鳍片, 其中, 该基座包含一箱体, 该箱体内部具有一容置空间。 所述的散热鳍片, 其中, 该基座更包含一凸缘, 自该箱体的周围向外突出。 综上所述, 本发明可先以成型制作过程 (例如, 铝拉钉制作过程) 成型散 热鳍片, 以表面处理制作过程于散热鳍片的固定部的表面形成咬合结构, 再以 压铸制作过程将熔化金属材料成型包覆散热鳍片的固定部的基座。 本发明的散 热鳍片具有防溢料结构, 且防溢料结构可于压铸制作过程中防止熔化金属材料 溢出造成毛边。 由于本发明的散热鳍片以成型制作过程成型, 本发明的散热鳍 片可不需现有散热鳍片的脱模角。 因此, 本发明的散热鳍片的重量较轻, 且鳍 片高度亦可做得比现有散热鳍片高。 此外, 在相同大小的散热装置中, 本发明 的散热鳍片数量可装设比现有散热鳍片多,进而增加散热面积,提高散热性能。 再者, 形成于散热鳍片的固定部的表面上的咬合结构可于压铸制作过程中有效 抓住金属材料, 进而增加基座与散热鳍片的结合强度。

防溢料结构 324的宽度 W1大于散热部 320的宽度 W2且防溢料结构 324 的宽度 W1大于凹槽结构 326中的固定部 322的宽度 W3。 于此实施例中, 防溢 料结构 324 自 KJ槽结构 326中的固定部 322向外突出的长度 L可介于 1毫米与 10毫米之间, 其中防溢料结构 324为等厚度。 于另一实施例中, 防溢料结构 324 的厚度亦可呈梯度变化。
于此实施例中, 基座 30可包含一箱体 300以及一凸缘 302, 其中箱体 300 内部具有一容置空间 304 , 且凸缘 302 自箱体 300的周围向外突出。 于实际应用 中, 可利用螺丝锁固、 铆接、 焊接或其它固定方式将凸缘 302固定于固定平面 上, 进而将散热装置 3固定于固定平面上。 当本发明的散热装置 3设置于户外 时 (例如, 基地台) , 有散热需求的电子元件可容置于基座 30的箱体 300内部 的容置空间 304中, 以保护电子元件免于遭受风吹雨打而损坏。
请参阅图 6 ,图 6为图 2至图 4中的散热装置 3的制造方法的流程图。首先, 执行步骤 S 100 , 以一成型制作过程成型多个散热鳍片 32。 于此实施例中, 上述 的成型制作过程可为一铝拉钉制作过程, 以使每一个散热鳍片 32成型为一圆柱 型散热鳍片。 接着, 执行步骤 S 102 , 以一表面处理制作过程于每一个散热鳍片 32的固定部 322的表面形成咬合结构 328。 接着, 执行步骤 S 104 , 将每一个散 热鳍片 32放入一模具(未显示) 中。 接着, 执行步骤 S 106 , 将一熔化金属材料 (例如, 铝等) 注入模具中。 最后, 执行步骤 S 108 , 以一压铸制作过程将熔化 金属材料成型基座 30, 其中基座 30包覆每一个散热鳍片 32的固定部 322, 如 图 4所示。 于此实施例中, 每一个散热鳍片 32的防溢料结构 324可于压铸制作 过程中防止熔化金属材料溢出造成毛边。 当防溢料结构 324 自凹槽结构 326中 的固定部 322向外突出的长度 L介于 1毫米与 10毫米之间时, 即可于压铸制作 过程中有效防止熔化金属材料溢出造成毛边。 此外, 每一个散热鳍片 32的凹槽 结构 326与咬合结构 328可有效抓住金属材料, 以增加基座 30与散热鳍片 32 的结合强度。

相较于现有技术, 本发明可先以成型制作过程 (例如, 铝拉钉制作过程) 成型散热鳍片, 以表面处理制作过程于散热鳍片的固定部的表面形成咬合结构, 再以压铸制作过程将熔化金属材料成型包覆散热鳍片的固定部的基座。 本发明 的散热鳍片具有防溢料结构, 且防溢料结构可于压铸制作过程中防止熔化金属 材料溢出造成毛边。 由于本发明的散热鳍片以成型制作过程成型, 本发明的散 热鳍片可不需现有散热鳍片的脱模角。 因此,本发明的散热鳍片的体重量较轻, 且鳍片高度亦可做得比现有散热鳍片高。 此外, 在相同大小的散热装置中, 本 发明的散热鳍片数量可装设比现有散热鳍片多, 进而增加散热面积, 提高散热 性能。 再者, 形成于散热鳍片的固定部的表面上的咬合结构可于压铸制作过程 中有效抓住金属材料, 进而增加基座与散热鳍片的结合强度。
以上所述仅为本发明的较佳实施例, 凡依本发明申请专利范围所做的均等 变化与修饰, 皆应属本发明的涵盖范围。
