各一方のヒートシンク部材７と他方のヒートシンク部材９とについて、フィン５の高さｈ１を任意の所定高さｈ２のフィン切断位置Ａで切断し、図１（ｂ−１）（ｂ−２）に示す高さ寸法ｈ２の一方のヒートシンク部材７と、他方のヒートシンク部材９にする。
次に、図１（ｃ−２）に示すように、他方のヒートシンク部材９を水平方向で１８０度回転する。
そして、図１（ｄ）で示すように、図１（ｃ−１）で示す一方のヒートシンク部材７に図１（ｃ−２）で示す他方のヒートシンク部材９を、一方のヒートシンク部材７の各フィン５の先端５ａが他方のヒートシンク部材９の溝１１（図１（ｅ）の拡大図参照）に、他方のヒートシンク部材９の各フィン５の先端５ａが一方のヒートシンク部材７の溝１１に嵌るように、一方のヒートシンク部材７と他方のヒートシンク部材を互いに嵌合する。
その後、図１（ｅ）に拡大して示すように一方のヒートシンク部材７の左端にある一方の溝壁（垂直壁）１１ａをカシメ治具１３でカシメ固定する。同様に、他方のヒートシンク部材９の右端にある一方の溝壁（垂直壁）１１ａをカシメ治具１３でカシメ固定する。 Next, a method of manufacturing the heat sink 1 having a height H2 shown in FIG. 4 will be described with reference to FIG.
As shown in FIGS. 1 (a-1) and 1 (a-2), one heat sink member 7 and the other heat sink member 9 are heat sink members of the same type, and the height H1 shown in FIG. 3 (a-2). It is used for manufacturing the heat sink 1.
For each one heat sink member 7 and the other heat sink member 9, the height h1 of the fin 5 is cut at the fin cutting position A of an arbitrary predetermined height h2, and FIGS. 1 (b-1) and 1 (b-2) show. One heat sink member 7 having the height dimension h2 shown and the other heat sink member 9 are used.
Next, as shown in FIG. 1 (c-2), the other heat sink member 9 is rotated 180 degrees in the horizontal direction.
Then, as shown in FIG. 1 (d), the other heat sink member 9 shown in FIG. 1 (c-2) is attached to one heat sink member 7 shown in FIG. 1 (c-1), and each of the heat sink members 7 is attached. The tip 5a of the fin 5 fits into the groove 11 of the other heat sink member 9 (see the enlarged view of FIG. 1E), and the tip 5a of each fin 5 of the other heat sink member 9 fits into the groove 11 of one heat sink member 7. As described above, one heat sink member 7 and the other heat sink member are fitted to each other.
After that, as shown in an enlarged manner in FIG. 1 (e), one groove wall (vertical wall) 11a at the left end of one heat sink member 7 is caulked and fixed with a caulking jig 13. Similarly, one groove wall (vertical wall) 11a at the right end of the other heat sink member 9 is caulked and fixed with the caulking jig 13.

次に、カシメ治具１３によるカシメ固定について詳しく説明する。
図２（ａ）に示すように、一方のシンク部材７の左端に位置する溝１１に他方のシンク部材９のフィン５の先端５ａを嵌合した状態で、図２（ｂ）に示すように、カシメ治具１３の先端部１３ａを、ベース３の左側にから一方の溝壁（垂直壁）１１ａに打ち込む。これにより、一方の溝壁１１ａがカシメ治具１３の先端部１３ａの形状に沿って凹むと共にフィン５側に食い込む凸部１４が形成されると共に、溝１１に嵌合している他方部材のフィン５の先端５ａが他方の溝壁１１ｂ側に突出する凸部１５が他方の溝壁１１ｂに食い込む。
その後、図２（ｃ）に示すように、カシメ治具１３を一方の溝壁１１ａから離して、カシメ固定が完了する。
上述した図２（ａ）〜（ｃ）のカシメ固定を、一方のシンク部材７で２箇所（図４参照）、他方のシンク部材９でも同様に２箇所おこなう。 Next, the caulking fixing by the caulking jig 13 will be described in detail.
As shown in FIG. 2A, with the tip 5a of the fin 5 of the other sink member 9 fitted in the groove 11 located at the left end of one sink member 7, as shown in FIG. 2B. , The tip portion 13a of the caulking jig 13 is driven into one groove wall (vertical wall) 11a from the left side of the base 3. As a result, one groove wall 11a is recessed along the shape of the tip portion 13a of the caulking jig 13, and a convex portion 14 that bites into the fin 5 side is formed, and the fin of the other member fitted in the groove 11 is formed. The convex portion 15 at which the tip 5a of 5 projects toward the other groove wall 11b bites into the other groove wall 11b.
After that, as shown in FIG. 2C, the caulking jig 13 is separated from one groove wall 11a, and the caulking fixing is completed.
The caulking of FIGS. 2 (a) to 2 (c) described above is performed at two locations on one sink member 7 (see FIG. 4) and at two locations on the other sink member 9.

第１実施の形態に係るヒートシンクの製造方法の作用効果について説明する。
上述した実施の形態によれば、図３（ａ−１）に示す一方及び他方のヒートシンク部材７、９をそのまま用いて、図３（ａ−２）に示す高さＨ１のヒートシンク１を製造することもできるし、図３（ｂ−１）に示すように、フィン５を切断して高さを変えることで、図３（ｂ−２）に示すように、Ｈ１よりも低い高さＨ２のヒートシンク１を製造できるから、ヒートシンク部材７、９の種類が少なくても様々な高さ寸法のヒートシンクを製造できる。
図３（ａ−１）及び（ｂ−１）に示すように、一方のヒートシンク部材７と他方のヒートシンク部材９は同種のものであり、フィン５を所定高さｈ２で切断したものを用いて、図３（ａ−２）に示す高さＨ１のヒートシンク１と、図３（ｂ−２）に示す異なる高さ寸法Ｈ２のシートシンク１を製造できるから、一方のヒートシンク部材７と他方のヒートシンク部材９はアルミ押出形材である場合、押出金型１つで異なる高さのヒートシンク１に対応でき、高さＨの異なる種類のヒートシンク１を製造する場合のコストを抑えられる。
図１（ｄ）（ｅ）に示すように、一方のヒートシンク部材７のフィン５、５間の溝１１に他方のヒートシンク部材９のフィン５が嵌まり込んでいるから、ヒートシンク１の製造時において、両ヒートシンク部材７、９を組み合わせる際に位置決めがし易い。 The operation and effect of the heat sink manufacturing method according to the first embodiment will be described.
According to the above-described embodiment, the heat sink 1 having a height H1 shown in FIG. 3 (a-2) is manufactured by using the one and the other heat sink members 7 and 9 shown in FIG. 3 (a-1) as they are. It is also possible, as shown in FIG. 3 (b-1), by cutting the fin 5 and changing the height, as shown in FIG. 3 (b-2), the height H2 is lower than H1. Since the heat sink 1 can be manufactured, heat sinks having various height dimensions can be manufactured even if there are only a few types of heat sink members 7 and 9.
As shown in FIGS. 3 (a-1) and 3 (b-1), one heat sink member 7 and the other heat sink member 9 are of the same type, and fins 5 are cut at a predetermined height h2. Since the heat sink 1 having a height H1 shown in FIG. 3 (a-2) and the seat sink 1 having a different height dimension H2 shown in FIG. 3 (b-2) can be manufactured, one heat sink member 7 and the other heat sink can be manufactured. When the member 9 is an extruded aluminum profile, one extrusion mold can handle heat sinks 1 having different heights, and the cost of manufacturing heat sinks 1 of different types having different heights H can be suppressed.
As shown in FIGS. 1 (d) and 1 (e), since the fin 5 of the other heat sink member 9 is fitted in the groove 11 between the fins 5 and 5 of one heat sink member 7, at the time of manufacturing the heat sink 1. , It is easy to position when combining both heat sink members 7 and 9.

以下に本発明の他の実施の形態を説明するが、以下に説明する実施の形態において、上述した第１実施の形態と同一の作用効果を奏する部分には同一の符号を付することによりその部分の詳細な説明を省略し、以下の説明では第１実施の形態と主に異なる点を説明する。
図５及び図６を参照して、本発明の第２実施の形態にかかるヒートシンクの製造方法を説明する。
第２実施の形態にかかるヒートシンクの製造方法は、様々な巾寸法（フィン５の列設方向Ｘの寸法）Ｘ１（図４参照）のヒートシンクを製造する方法である。
図５（ａ−１）及び（ａ−２）に示すように、同種の一方及び他方のヒートシンク部材７、９を用いて、図５（ｂ−１）に示すように、一方のヒートシンク部材７ではその巾方向の左端側（図５（ｂ−１）において左端側）で、一つの溝１１を含む端部部分１９を巾方向の切断位置Ｂで切断する。また、図５（ｂ−２）に示すように、他方のシンク部材９では、その巾方向の右端側（図５（ｂ−２）において右端側）で、一方のヒートシンク部材７と同様に、巾方向の切断位置Ｂで切断するが、他方のヒートシンク部材９では、一方の溝壁（垂直壁）１１ａを右端に残す位置で切断する。
次に、図５（ｃ−１）に示すように、他方のシンク部材９を上下に１８０度回転して、ベース３を上にフィン５を下にする。
その後、図５（ｄ）に示すように、一方のヒートシンク部材７の各フィン５の先端５ａが他方のヒートシンク部材９の溝１１（図５（ｂ−２）の拡大図参照））に、他方のヒートシンク部材９の各フィン５の先端５ａが一方のヒートシンク部材７の溝１１（図５（ｂ−１）の拡大図参照））に嵌るように、一方のヒートシンク部材７と他方のヒートシンク部材を互いに嵌合する。
その後、図１（ｅ）に拡大して示すように、他方のヒートシンク部材９の左端にある一方の溝壁（垂直壁）１１ａをカシメ治具１３でカシメ固定する。同様に、他方のヒートシンク部材９の右端にある一方の溝壁（垂直壁）１１ａをカシメ治具１３でカシメ固定する。 Other embodiments of the present invention will be described below, but in the embodiments described below, the portions exhibiting the same effects as those of the above-described first embodiment are designated by the same reference numerals.

Is cut at the cutting position B in the width direction. Therefore, when one heat sink member 7 and the other heat sink member 9 are extruded aluminum profiles, one extrusion mold can handle heat sinks 1 having different widths. It is possible to reduce the cost of manufacturing heat sinks 1 having different dimensions in the width direction (the direction in which the fins are arranged) X.
As shown in FIGS. 5 (d) and 5 (e), since the fin 5 of the other heat sink member 9 is fitted in the groove 11 between the fins 5 and 5 of one heat sink member 7, at the time of manufacturing the heat sink 1. , It is easy to position when combining both heat sink members 7 and 9.
As shown in FIG. 5 (b-2), the base 3 has one groove wall (vertical wall) 11a for caulking and fixing between the fins 5 and 5, and one groove wall (vertical wall) 11a. Since the heat sink 1 is cut at the end position, one groove wall (vertical wall) 11a as a caulking portion is located at the end no matter where in the width direction (fin row arrangement direction) X of the heat sink 1 is cut. Therefore, the caulking work is easy.
