介してネジ23で結合する。2. Description of the Related Art There are various types of such heat sinks. For example, the type shown in FIG. 19 has a large number of metal fins 19 made of aluminum or the like between metal plates 17 and 21 made of aluminum or the like facing each other. The protruding wall portions 24 are formed in parallel with each other, and the protruding wall portions 24 are formed on one of the metal plates 17 at appropriate intervals, and one end of the fin 19 is inserted into the groove 18 formed by the protruding wall portion 24. The fins 19 are fixed to the metal plate 17 by crimping the portions 24 on both sides of the fins 19, and the other ends of the fins 19 are inserted into the groove 20 formed in another metal plate 21. Then, the metal plates 17 and 21 facing each other are coupled by screws 23 via the side plates 22.

【発明が解決しようとする課題】フィン19の両側で突壁
部24をカシメることで金属プレート17にフィン19を固定
するため、図20に示すようにこのカシメ部分では両者の
接触面積が少なく、金属プレート17とフィン19との熱伝
導率が低い。Since the fins 19 are fixed to the metal plate 17 by crimping the projecting wall portions 24 on both sides of the fins 19, the contact area between the fins 19 is small in this crimping portion as shown in FIG. The heat conductivity between the metal plate 17 and the fins 19 is low.
【０００４】なお、フィン19の一側の突壁部24のみをフ
ィン19の側に押圧してフィン19を金属プレート17に固定
することも可能であるが、かかる構成を採用しフィン19
の一側の突壁部24のみを押圧すると他側の突壁部24が変
形するおそれがあり、確実に固定できない。It is also possible to press only the projecting wall portion 24 on one side of the fin 19 toward the fin 19 side to fix the fin 19 to the metal plate 17, but such a structure is adopted.
If only the protruding wall portion 24 on one side is pressed, the protruding wall portion 24 on the other side may be deformed and cannot be reliably fixed.

緊結も困難となる。Further, in this case, the other side of the fin 19 where the protruding wall portion 24 is not pressed is supported by the groove 18 which is recessed in the metal plate 17, but this portion and the protruding wall on the side pressed. Since the height of the clamping position is different from that of the part 24,
The contact area between 19 and metal plate 17 is also small,
Tightness also becomes difficult.

ンクを提供することにある。The object of the present invention is to eliminate the disadvantages of the prior art and to increase the contact area between the fin and the substrate to increase the thermal conductivity even when only one side of the fin is fixed to the substrate by crimping. Another object of the present invention is to provide a heat sink that can be increased in height, can be easily fixed by crimping, and can reliably prevent the fin from coming off after fixing.
