があつた。Conventional technology Semiconductor elements and integrated circuits such as transistors and thyristors have conventionally been used in electronics-related products such as stereo amplifiers and OA equipment.
Since ICs and the like generate heat, they were attached to a heat sink made of aluminum (including aluminum alloy), as shown in FIGS. 3 and 4, for example.
In this conventional heat sink, a large number of tongue-like fins 12 are formed on both sides of the vertical wall portion of the heat dissipation base 11 by cutting the fin-standing surfaces of a plate-like material. The tongue-like fin 12 was formed with a sharply pointed tip 12a. Therefore, when incorporating such a heatsink into an electronics-related product such as a stereo amplifier, there is a risk that a worker may cut his/her hand due to the sharp tip 12a of the tongue-like fin 12, which is extremely dangerous. There was a problem. In addition, since the sharp tip 12a of the tongue-like fin 12 is thin, the tip of the fin 12a may be touched by the operator's hand.
There is a problem in that the fins 12 tend to break into small pieces and fall off, and such pieces of the fin 12 cause problems such as shorts in equipment such as stereo amplifiers.

We have proposed a radiator in which a flat inclined surface portion 24 is formed by cutting off both the upper and lower corners of each end surface portion 23 diagonally (see Japanese Utility Model Application Publication No. 12692/1983). ). however,
In the future proposal, after the process of carving and raising the tongue-like fins 22, it is necessary to perform a process of removing the sharp tips 22a and corners, which increases the number of processes and makes manufacturing the radiator troublesome. It was hot. Furthermore, although the end face 23 and the inclined face 24 of each tongue-like fin 22 are certainly flat, these edges are sharp, which poses a risk of cutting the operator's hand, which is extremely dangerous. There was a problem.

A shaped aluminum heat dissipation base 2 is formed by cutting the finned surfaces of the material on both sides of the vertical wall portion 1a, and the outer half is separated into four by horizontal slits 4. Each fin division 6 is formed by a large number of mutually parallel tongue-shaped fins, and each fin division 6 is provided with a winding edge 3 with a pointed tip 2a directed inward. These winding edges 3 are formed at the same time when the tongue-like fins 2 are carved up by cutting. This is carried out, for example, by using a cutting tool having a guide surface that curls the tip of the tongue-like fin 2 that has been cut and raised. Reference numeral 5 denotes a horizontal wall portion integrally provided at the lower edge of the vertical wall portion 1a of the heat dissipation base 1, to which a heat generating element such as a transistor is attached.

に防止しうるという効果を奏する。Effects of the invention As described above, the heatsink according to this invention has a plurality of tongue-shaped slits 4 having an arcuate horizontal cross section and horizontal slits 4 on at least one side of the aluminum heatsink base 1 to which a heat generating element such as a transistor is attached. The fins 2 are formed by carving and raising the fins 2 in parallel, and a sharp tip 2a that is formed simultaneously with the carving and raising of the fins 2 is attached to the tip of the fin division part 6 divided by the slit 4 of each tongue-like fin 2. Since the winding edge portion 3 is provided with the tongue-like fin 2 facing toward
It is possible to reliably prevent the user from cutting his/her hand with the tip 2a of the blade, and therefore, the safety is extremely high. Further, the winding edge portion 3 can be formed at the same time as the tongue-like fin 2 having an arcuate horizontal cross section is cut and raised, and the tongue-like fin 2 is divided into several fin division portions 6 by the slits 4. Therefore, the length of the edge to be rolled up in the vertical direction is short, and the winding operation is easy, and therefore the manufacture of the heat sink is very simple. Furthermore, since the thin, pointed tip 2a of each tongue-shaped fin 2 is rolled up inward, there is a possibility that a thin piece of the tongue-shaped fin 2 may fall off if the operator's hand hits this tip 2a. Therefore, it is possible to effectively prevent troubles from occurring in electronics-related products such as stereo amplifiers due to such thin-walled fragments.
