本発明は放熱器の製造法、詳しくは基板に設け
た溝にフインを嵌合し、これを該基板にかしめ結
合する方法の改良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, and more particularly to an improvement in a method for fitting fins into grooves provided in a substrate and caulking the fins to the substrate.
従来この種の放熱器としては基板にフインを極

号）。 Conventionally, this type of heatsink has fins placed on the board at extremely narrow intervals, e.g. 0.3mm, with fin spacing of around 2mm.
A method is known in which a thin fin with a thickness of about mm is inserted into a groove provided in a substrate, and a spacer plate having a chevron-shaped tip and a long groove corresponding to the fin is used to crush the convex portion of the substrate and swage the fin. (Tokuko Showa 36-9565
issue).
又溝付の基板を押出型材で作り、それらの溝に
フインを立て両者をかしめ結合する方法も考えら
れている。 A method has also been considered in which a grooved substrate is made of extruded material, fins are placed in the grooves, and the two are caulked together.

取付間隔を前者の方法のように極めて狭い間隔に
設定できないという欠点をもつている。 The former method has the advantage of providing a heatsink with high heat dissipation efficiency by installing the fins at extremely narrow intervals, but on the other hand, the contact area between the fins and the caulking part of the board is restricted due to the thickness of the board, making it difficult to reduce the length of the fins. The problem is that it cannot be harvested in large quantities. The latter method has the advantage of not having to cut the grooves with a metal saw because the grooved substrate is extruded and the fins can be caulked into the grooves, but the former method has the advantage of not having to cut the grooves with a metal saw. It has the disadvantage that it cannot be set to extremely narrow intervals such as .

り所期の目的を収めたものである。 The present invention provides a novel method for manufacturing a heat sink that combines the advantages of these methods. The substrate is an extruded material having a cross-sectional shape with many protrusions formed on one or both sides, and the top surface of these protrusions is The desired purpose is achieved by cutting grooves for fin fitting, fitting plate-shaped fins into these grooves, pressing the above-mentioned protrusions from both sides of the fins, and caulking the fins to the substrate. It is.
本発明によれば押出型材は突条を隆起形成した

る。 According to the present invention, since the extruded material is in the shape of a substrate with raised protrusions, these protrusions can be formed at extremely narrow intervals, and the fins to be later attached to the grooves cut here. The mounting interval (pitch) can also be set small. In addition, since the groove is cut into the raised ridge, the depth of the groove can be made sufficiently large according to the thickness of the ridge without being restricted by the thickness of the board, and the length of the fin to be attached is also sufficient. It is possible to make it larger.
又フインと基板とのかしめ部は爪状に隆起した
突条の両側よりフインを挾んで押しつぶすように
してかしめられているので、フインと基板とのか
しめ部における密着面積が大きいのみならず密着
度も高く信頼性のあるかしめ結合が得られる。 In addition, the caulking part between the fin and the board is caulked by pinching and crushing the fin from both sides of the claw-like protrusions, so that not only is the area of contact between the fin and the board large, but also the degree of adhesion is high. A highly reliable caulking connection can be obtained.
