に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a heat sink in which fins are caulked and bonded to grooves provided on a substrate, and more specifically, a substrate in which fin mounting grooves having protruding wall portions for fin caulking are arranged is extruded into a molded material. The present invention relates to a method of manufacturing a heat radiator, in which a round bar serving as a heat radiating fin fitted into the groove is caulked and connected by pressing the projecting wall portion.
従来この種の放熱器において、基板にフインを
極めて狭い間隔で例えば２mm前後のフイン間隔で
0.3mm前後と薄い厚さのフインを植込む方法とし
てはフインを基板に設けた溝に嵌入し、山形先端
部とフインに対応する長溝を有する間隔板をもつ
て該基板の凸部を押しつぶしてフインをかしめる
方法が知られている（特公昭36−9565号公報）。 Conventionally, in this type of heatsink, fins are placed on the board at extremely narrow intervals, for example, with a fin spacing of around 2 mm.
A method for implanting fins with a thin thickness of around 0.3 mm is to fit the fins into grooves provided on the substrate, and to crush the convex portions of the substrate using a spacing plate having a chevron-shaped tip and a long groove corresponding to the fins. A method of caulking the fins is known (Special Publication No. 36-9565).
この方法の場合、基板の表面にメタルソー（金
属鋸）による溝入れの工程が必要であり、又フイ
ンのかしめ工程も特定の治具を必要とする等の問
題がある。 This method requires a process of making grooves on the surface of the substrate using a metal saw, and also requires a specific jig for the process of caulking the fins.
本発明はこのような問題に対処してなされたも

る。 The present invention has been made to address these problems, and by using an extruded molded material with grooves as the substrate, the grooving process using a metal saw is not necessary. By forming the projecting wall portion in advance and using a round bar pin as a heat dissipation fin, the caulking work is simplified and the caulking strength is also improved.

基板にかしめ結合することを特徴としている。 That is, the present invention uses as a substrate an extruded material having a cross-sectional shape arranged on the surface of a heat dissipation fin mounting groove having protruding wall parts for fin caulking on the left and right sides, separated by a groove part formed between the outer sides of the protruding wall parts. The present invention is characterized in that a round bar pin as a heat dissipating fin is set up in the heat dissipating fin mounting groove of the board, and the left and right protruding walls are crushed in the direction of the groove to caulk and connect the round bar pin to the board.

て大きいという利点もある。 According to the present invention, the round bar pin set in the groove can be fixed by wrapping the left and right heat dissipation fins that are crushed in the direction of the groove with the caulking projecting wall, thereby ensuring close contact between the round bar pin and the board. It also has the advantage of being extremely strong.
以下に本発明を図面に示す実施例によつて説明
する。 The present invention will be explained below with reference to embodiments shown in the drawings.

いかやゝ大き目とされている。 As shown in FIGS. 1 and 2, the substrate 1 is made of an extruded aluminum or aluminum alloy material, and has a heat dissipation fin mounting groove 3 on the surface thereof, which has protruding walls 2 and 2' for caulking the left and right heat dissipation fins, respectively. It has a structure in which the protruding wall parts 2 and 2' are sequentially arranged with a groove part 5 formed between them being separated. The total height of the left and right protruding walls 2, 2' is approximately equal to or slightly larger than the inner width of the groove 3.
その際左右の放熱フインかしめ用突壁部２，

斜したテーパー状としてある。 At that time, the left and right heat dissipation fin caulking projecting wall parts 2,
2' is tapered slightly in the direction of the groove 3, as shown, in order to facilitate and ensure caulking of the radiation fins.

定されている。 The heat dissipation fin used in the present invention is a round bar pin 4 as shown in FIGS. 3 and 4.
The outer diameter is set to be equal to or slightly smaller than the distance between the tapered tips of the left and right protruding walls 2, 2'.
そこで丸棒ピン４は第３図に示すように左右の

As shown in the figure, when the left and right protruding walls 2, 2' are crushed in the direction of the groove 3, the round bar pin 4 is held so as to be wrapped from the left and right by the protruding walls 2, 2', and is held in the same groove 3. The left and right protruding walls 2, 2' are closely connected between the round bar pin 4 set up inside, and the round bar pin 4 is fixed in such a way that the left and right protruding walls 2, 2' surround each other separately and independently. It's going to be a success.
