【0001】
【考案の属する技術分野】
この考案は放熱フィンの構造に係り、特に各放熱片は、ギャップを保持し且つ垂直度を固定するために、同様な長さの間隔片を有する放熱フィンの構造に関する。
【0002】
【従来の技術】
図6に示すのは従来の放熱フィンである。従来の放熱フィンは台座6を有し、前記台座6には等距離に並列し片状に呈する多数の放熱片61が設けられており、且つ前記各放熱片61を等距離に固定するように、二つのロッド62が前記各放熱片61を横方向に貫通しており、放熱ファン(図示せず)を固定するために、前記各放熱片61の頂縁にはフレーム63が設けられている。上記構成の放熱フィンを放熱必要な部材(例えば、パソコンのCPUまたは熱伝導リード)に組み付けて、前記放熱ファンによりエアを前記各放熱片61の間で流動させ、各放熱片61まで伝導されてきた熱を放熱する。
【0003】
これには次のような欠点があった。
(イ)エアの流通のために、前記放熱フィンの各放熱片61の間には一定のギャップを保持することが必要なので、前記ロッド62を利用して前記各放熱片61の間のギャップを固定するが、前記各放熱片61は一個一個に溶接または粘着などの方法により前記ロッド62に固定する必要なため、製造に手間がかなり掛かり、製造コストが無駄に増加した。
(ロ)前記各放熱片61は一個一個に溶接または粘着などの方法により前記ロッド62に固定したため、各放熱片61の間のギャップの長さはズレる可能性があるので、熱対流の効果に悪影響を与えた。そして、前記放熱片61と前記ロッド62の接触面積が小さいため、安定性が低く且つ変形し易いので、各放熱片61が変形して互いに寄ったことがよくあり、放熱効果が低下した。
【0004】
【考案が解決しようとする課題】
よって本考案の目的は、エアが順調に流動し、放熱片が歪まず、熱を快速に放熱して温度を有効に低減させることができる放熱フィンの構造を提供することである。
【0005】
【課題を解決するための手段】
上記欠点を解決するためになされた本考案の請求項1は、多数の並列している片状の放熱片と、連接部材と、を含み、前記各放熱片の間には同様な長さのギャップを有し、前記各放熱片は前記連接部材に嵌めて固定する放熱フィンの構造において、前記各放熱片の中央にはそれぞれ貫通孔を有し、前記貫通孔の各周縁には別々に外側へ伸びた間隔片を有し、前記間隔片の外側へ伸びた長さは、前記各放熱片の間のギャップの長さと一致し、前記各放熱片が前記連接部材に順に嵌めて固定するために、前記連接部材は前記放熱片の貫通孔に合う形状を有し、且つ前記各放熱片の間のギャップは、前記各放熱片の間隔片により固定したことを特徴とする放熱フィンの構造であることを要旨としている。
【0006】
本考案の請求項2では、前記放熱片の貫通孔はプレスで成形された四角形の孔であり、且つ四角形の孔の四辺には別々に同様な長さの間隔片が形成しており、前記各放熱片を嵌めて固定するために、前記連接部材は四方形体であることを特徴とする請求項1に記載の放熱フィンの構造であることを要旨としている。
【0007】
本考案の請求項3では、前記連接部材の内部には、両端が貫通した状態を持つ放熱空間を有することを特徴とする請求項1に記載の放熱フィンの構造であることを要旨としている。
本考案の請求項4では、前記連接部材の放熱空間の内部には、前記放熱片の方向と垂直に多数の金属シートが設けられていることを特徴とする請求項3に記載の放熱フィンの構造であることを要旨としている。

【考案の実施の形態】
図1から図3に示すのは、本考案の一実施例による放熱フィンの構造であり、その放熱フィンは、多数の並列している片状の放熱片1と、連接部材2と、を含み、前記各放熱片1の間には同様な長さのギャップ11を有し、前記各放熱片1は前記連接部材2に嵌めて固定されている。
また、前記各放熱片1の中央にはそれぞれ貫通孔12を有し、前記貫通孔12の各周縁には別々に外側へ伸びた間隔片13を有し、前記間隔片13の外側へ伸びた長さは、前記各放熱片1の間のギャップ11の長さと一致し、本実施例では、前記貫通孔12はプレスで成形された四角形の孔であり、且つ四角形の孔の四辺には別々に同様な長さの間隔片13が形成している。
【0010】
前記各放熱片1の貫通孔12に嵌めて固定するために、本実施例では、前記連接部材2は、四方形体であり前記放熱片1の貫通孔12に合う形状を有し、且つ前記各放熱片1の間のギャップ11は前記間隔片13により固定し、前記連接部材2の内部には、両端が貫通した状態を持つ放熱空間21を有し、前記放熱空間21の内部には、前記放熱片1の方向と垂直した多数の金属シート22が設けられている。

【0012】
該当放熱片1は間隔片13により連接部材2に嵌めて固定し、且つ各放熱片1の外側へ伸びた間隔片13の長さが同様であるため、前記各放熱片1の間のギャップ11が等距離に保持し固定することができ、エアが順調に流動することができるので、熱対流の効果を向上することができる。該当間隔片13は、更に放熱片の垂直度を固定し、放熱片1が歪まないので、放熱効果を向上することができる。
【0013】
該当放熱フィンの各放熱片1の頂端では第一放熱ファン3が設けられており、前記連接部材2の内部には放熱空間21を有し、前記放熱空間21の内部には金属シート22を有し、且つ前記放熱空間21の一端では第二放熱ファン4が設けられているため、各放熱片1まで伝導されてきた熱は前記第一放熱ファン3により放熱させてから、第二放熱ファン4により前記連接部材2の内部にある放熱空間21のなかのエアを流動させ、残った熱を放熱するため、二重の放熱効果が得られる。

[Technical field to which the invention belongs]

[0002]
[Prior art]
FIG. 6 shows a conventional radiation fin. The conventional heat dissipating fin has a pedestal 6, and the pedestal 6 is provided with a large number of heat dissipating pieces 61 which are arranged in parallel at equal distances and present in a strip shape, and the heat dissipating pieces 61 are fixed at equal distances. , Two rods 62 penetrate the heat radiating pieces 61 in the lateral direction, and a frame 63 is provided at the top edge of each heat radiating piece 61 to fix a heat radiating fan (not shown). . The radiating fins having the above-described structure are assembled to a member (for example, a CPU of a personal computer or a heat conducting lead) that needs to radiate heat, and the radiating fan causes air to flow between the radiating pieces 61, and is conducted to the radiating pieces 61. Dissipates heat.
[0003]
This had the following disadvantages.
(A) Since a certain gap is required to be maintained between the heat radiating pieces 61 of the heat radiating fins for the flow of air, the gap between the heat radiating pieces 61 is reduced by using the rod 62. However, the heat radiation pieces 61 need to be fixed to the rod 62 one by one by welding or adhesion, so that it takes much time and effort to manufacture, and the manufacturing cost increases wastefully.
(B) Since the heat radiation pieces 61 are fixed to the rod 62 one by one by welding or adhesion, the length of the gap between the heat radiation pieces 61 may be shifted. Had an adverse effect. Since the contact area between the heat radiation piece 61 and the rod 62 is small, the stability is low and the rod is easily deformed. Therefore, the heat radiation pieces 61 are often deformed and come close to each other, and the heat radiation effect is reduced.
[0004]
