The classification of conventional heat sinks is as follows: Fig. 1, Fig. 2,
It can be divided into the types shown in Figure 3.
First, referring to FIG. 1, a U-shaped flat plate heat sink 2 is attached to a substrate 1, and a transistor 3 is further attached to the heat sink 2. As shown in FIG. in this case,
Even if the transistor 3 is attached to the heatsink 2 on the side of the substrate 1, there is an advantage that the transistor 3 can be directly attached to the substrate 1 because it is located almost in the middle of the heatsink 2 and heat is dissipated evenly. It is mainly used as a heat sink for low-power transistors, and because it is processed into a flat plate, it can be made at low cost. Next, referring to FIG. 2, a transistor 3 is mounted through a socket 4 in order to be located approximately in the center of the finned heat sink 2. Similarly, in FIG. 3, a transistor 3 is attached via a socket 4 to approximately the center of a heat sink 2 utilizing a chimney effect. Both FIGS. 2 and 3 have high heat dissipation efficiency and are used as heat radiators for high-power transistors, but they have the drawback of high cost in terms of materials and processing.

FIG. 4 shows an embodiment of the present invention, in which the flat plate 5 is formed into a U-shape, and the opposing plates 51 and 52 of the U-shape are alternately bent inside the U-shape to form a hollow This radiator is formed into a rectangular parallelepiped-shaped cylinder 53, and has a through hole 54 provided in the lower part of the hollow rectangular parallelepiped-shaped cylinder 53. If the transistor 3 is installed almost in the center of the hollow rectangular cylinder 53, the air heated by the transistor 3 will flow through the cylinder 53 as shown by the arrow in the figure.
The surrounding air flows along the inside and circulates, dissipating heat.

As described above, it can be obtained at low cost because it is made by press processing a flat plate, and even if the transistor is mounted directly on the board, there is no need for a socket because it is located almost in the middle of the heat sink, and a heat sink with high heat dissipation efficiency due to the chimney effect can be obtained. It will be done.
