【0011】
【発明の実施の形態】
以下、図面を参照して、本発明のピン形フィンを備えたヒートシンクの製造方法について説明する。
【0012】
図1は、本発明における第1実施形態の方法を実施するための装置の概略を示したものであり、この装置は、適当な駆動装置(図示略)に接続され、かつ用意された基板材料(1)が巻き取られているアンコイラー(2)と、アンコイラー(2)と同調して回転し、アンコイラー(2)から巻き戻され板状に復元した基板材料(1)を巻き取るリコイラー(図示略)と、アンコイラー(2)からリコイラーヘの基板材料(1)の搬送経路中に設置されたアークスタッドウェルダー(3)とを備えている。
【0013】
アンコイラー(2)に巻き取られている基板材料(1)は、アルミニウム展伸材であり、例えば厚さ1.5mm、幅30mmの板状に成形されたものである。
【0014】
アークスタッドウェルダー(3)の詳細な示は省略したが、アークスタッドウェルダー(3)は交流溶接用電源(4)、変圧器(5)、複数の載置形溶植ヘッド(6)等を備えたものである。
【0015】
図2に示したように載置形溶植ヘッド(6)は、基板材料(1)に溶接されるピン形フィン(7)をつかむチャック(6a)を備えており、内部にチャック(6a)に連通したフィン通路が形成されており、チャック(6a)に上方からピン形フィン(7)が随時送られ、送られてきたピン形フィン(7)がチャック(6a)に掴まれて基板材料(1)上にスタッド溶接されるようになされている。
【0016】
基板材料(1)上に溶接されるピン形フィン(7)は、例えば、直径1mm、高さ5mmの断面円形状でかつ先端部にテーパ状部を介して突部(7a)を有し、溶接時に適度なアークが発生するようになされている。
【0017】
上記の装置を用い、アンコイラー(2)から巻き戻されている基板材料(1)上に、ピン形フィン(7)が、例えば、前後左右に3mmの間隔をおいてアークスタッド溶接され、ピン形フィン(7)が基板材料(1)に植え付けられる。ピン形フィン(7)がスタッド溶接された基板材料(1)は、リコイラーに巻き取られる。リコイラーに巻き取られた基板材料(1)は、後に適当な切断装置により所定の大きさに切断され、ピン形フィンを備えたヒートシンクが完成する。なお、基板材料(1)とピン形フィン(7)のスタッド溶接に要する時間は0.004秒程度ときわめて短く、基板材料(1)の巻き戻しに影響を与えることはない。
【0018】
上記の方法においては、アーク溶接によりピン形フィン(7)が基板材料(1)に溶接されているが、抵抗溶接および衝撃溶接により溶接してもよい。
【0019】
つぎに、図3および図4を参照して、本発明における第2実施形態の方法を説明する。図3は、本発明における第2実施形態の方法を実施するための装置の概略を示したものであり、この装置は、図1に示した装置におけるスタッドウェルダー(3)に代えてアンコイラー(2)からリコイラーヘの基板材料(1)の搬送経路中に上流側から順に設置された上下一対の加熱装置(13)と、打ち抜き機(14)と、フィンはめ込み装置(15)とを備えている。
【0020】
加熱装置(13)、打ち抜き機(14)およびはめ込み装置(15)の詳細な図示は省略したが、加熱装置(13)は、交流電源(16)と、基板材料(11)の上下に位置し、かつそれぞれ交流電源(16)に接続されたコイルが巻かれている2個の発熱体(17)とを備えたものであり、打ち抜き機(11)は、基板材料(11)に、幅方向に並んだ孔(10)を1列ごとに形成するものであり、ピン形フィンはめ込み装置(15)は、ピン形フィン(12)をつかむ複数のチャック(18)を備え、上下に移動して形成された孔(10)1列ごとにピン形フィン(12)をはめ込むものである。
【0021】
そして、アンコイラー(2)にコイル状に巻き取られた基板材料(11)を間欠的に巻き戻して加熱装置(13)に送り、加熱した後、打ち抜き機(14)により基板材料(11)に打ち抜き加工を施してピン形フィン(12)を焼きばめることができる径の多数の孔(10)を形成する。そして、基板材料(11)が加熱されることにより膨張し、各孔(10)が拡径した状態において、あらかじめ押し出し加工等により製造されたピン形フィン(12)の下端部をはめ込み装置(15)により各孔(10)に嵌め入れる。この後、基板材料(11)を適当な冷却装置(図示略)により冷却し、各孔(10)を縮径して基板材料(11)にピン形フィン(12)を固定する。このようにして基板材料(11)の各孔(10)にピン形フィン(12)を焼きばめるのである。
【0022】
ピン形フィン(12)が焼きばめられた基板材料(11)は、リコイラーに巻き取られる。リコイラーに巻き取られた基板材料(11)は、その後適当な切断装置により所定の大きさに切断され、図4に示したように、基板(19)および基板(19)上に立設された多数のピン形フィン(12)を備えているヒートシンクが完成する。
【0023】
なお、ピン形フィン(12)は、断面円形状の基部から断面略台形状の歯が8つ放射状に突出した断面星形状をなしており、対向する歯の頂面を結んだ直線の常温における長さは、孔(10)の常温における直径よりわずかに大きく、かつ基板材料(11)を加熱し、これが膨張した状態における拡径時の孔(10)の径よりわずかに小さくなされている。
【0024】
上記のように、断面星形状のピン形フィン(12)を用いると、ピン形フィン(12)の表面積を大きくすることができ、放熱性に優れたヒートシンクを製造できる。
【0025】
また、上記第2の実施形態においては基板材料(11)にピン形フィン(12)を焼きばめているが、これとは逆に、適当な冷却装置により冷却された冷風をピン形フィンに吹き付けてピン形フィンを冷却縮径し、縮径したピン形フィンを基板材料の孔に嵌め入れた後にピン形フィンを加熱してピン形フィンを膨張拡径させ、孔にピン形フィンを固定するようにしてもよい。基板材料の孔は、常温におけるピン形フィンの径より小さく、冷却して縮径した状態におけるピン形フィンの径より大きい径の孔である。
なお、ピン形フィン(7)(12)は、アルミニウム等の熱伝導率に優れた材料を用いて製造すればよい。
【0026】
【発明の効果】
本発明のピン形フィンを備えたヒートシンクの製造方法によれば、コイル状に巻き取られた基板材料を用意し、基板材料を巻き出すとともに巻き出された基板材料上にピン形フィンをスタッド溶接するので、切削や鍛造によりヒートシンクを製造する場合に比し、製造コストが安くなるとともに、複雑な形状のピン形フィンを備えたヒートシンクを容易に製造することができる
【0027】
また、コイル状に巻き取られた基板材料を用意し、基板材料を巻き出すとともに巻き出された基板材料に多数の孔を形成し、各孔にピン形フィンの一端部を焼きばめても上記と同様の効果を得ることができる。
【0028】
さらに、コイル状に巻き取られた基板材料を用意し、基板材料を巻き出すとともに巻き出された基板材料に多数の孔を形成し、各孔に冷却縮径したピン形フィンの一端部を嵌め入れた後ピン形フィンを加熱拡径して孔にピン形フィンを固定しても上記と同様の効果を得ることができる。

Although the detailed disclosure of the arc stud welder (3) is omitted, the arc stud welder (3) power supply AC welding (4), the transformer (5), comprising a plurality of mounting-standing溶植head (6) or the like It is a thing.
[0015]
As shown in FIG. 2, the mounting type fusion head (6) is provided with a chuck (6a) that holds a pin-shaped fin (7) welded to the substrate material (1). A communicating fin passage is formed, and the pin-shaped fin (7) is sent to the chuck (6a) from above as needed, and the fed pin-shaped fin (7) is gripped by the chuck (6a) to form the substrate material ( 1) Stud welded on top.

Using the above device, pin-shaped fins (7) are arc-stud welded, for example, 3 mm from front to back and left and right on the substrate material (1) unwound from the uncoiler (2), and then pin-shaped. Fins (7) are implanted in the substrate material (1). The substrate material (1) on which the pin-shaped fin (7) is stud-welded is wound up by a recoiler. The substrate material (1) taken up by the recoiler is later cut into a predetermined size by an appropriate cutting device to complete a heat sink having pin-shaped fins. The time required for stud welding of the substrate material (1) and the pin-shaped fin (7) is as short as about 0.004 seconds and does not affect the unwinding of the substrate material (1).
[0018]
In the above method, the pin-shaped fin (7) is welded to the substrate material (1) by arc welding, but may be welded by resistance welding and impact welding.

Then, the substrate material (11) wound in a coil shape on the uncoiler (2) is intermittently rewound, sent to the heating device (13), heated, and then punched into the substrate material (11) by the punching machine (14). A number of holes (10) of a diameter that can be stamped to shrink the pin-shaped fins (12) are formed. Then, in the state where the substrate material (11) is heated to expand and the diameter of each hole (10) is expanded, the lower end portion of the pin-shaped fin (12) manufactured in advance by an extrusion process or the like is inserted (15 ) Fit into each hole (10). Thereafter, the substrate material (11) is cooled by a suitable cooling device (not shown), each hole (10) decreases in diameter to secure the pin-shaped fins (12) to the substrate material (11). In this way, pin-shaped fins (12) are shrink-fitted into each hole (10) of the substrate material (11).
[0022]
The substrate material (11) onto which the pin-shaped fins (12) have been shrink-fitted is taken up by a recoiler.
