There is one shown in Japanese Patent No.-122087. this is,
The selected heat pipes are placed concentrically at appropriate intervals in a mold for a secondary conductive layer ring made to correspond to the row-to-shell, and then cast in a conductive material such as aluminum that will become the secondary conductive layer ring. .

な）冷却能力に制限を受ける不具合を生じる。Hereinafter, one embodiment of the present invention will be described based on FIGS. 1 to 4. Fig. 1 is a longitudinal sectional view of the main part showing the state of the heat pipe material before expansion, and Figs. 2 and 8 are longitudinal sectional views, front views, and front views of the main part showing the state of the heat pipe material after expansion. FIG. 4 is a longitudinal sectional view showing the heat pipe after it is formed. First, a through hole (5a) overflowing in the axial direction is formed in the hollow roll (5).
) are formed approximately concentrically in the circumferential direction, and a roll (5
) A heat pipe tube material (6) having a diameter smaller than that of the through hole (5a) is inserted into the through hole (5a). Then, the heat pipe tube material (6) is expanded. Heat pipe tube material (6)
One end circle of the heat pipe material (6) is pushed inside while expanding the tube expansion tool (7) to the other end side of the heat pipe tube material (6) using a pressing force. By the way, for example, the roll (5) is made of iron, and the heat pipe material (6) is made of copper. Therefore, since copper is soft like iron, when the heat pipe material (6) is expanded,
The outer surface of the heat pipe tube material (6) is crushed and tightly bonded to the through hole (5a) of the roll (5),
The bonding force between the two becomes large and the adhesion becomes very good, so that the thermal resistance between the two can be significantly reduced. This is because, although it is generally thought that a heat pipe is inserted into the through hole (1a), an adhesive is interposed between the heat pipe and the through hole in order to fix the heat pipe and the through hole and ensure good adhesion. In this case, the required conditions for adhesion can be met, but in terms of adhesion, it is not possible to form a completely integrated structure between the two, and the adhesive has air bubbles and there are no gaps between the two. It is very difficult to completely fill the tank, resulting in a large thermal resistance and a problem that limits the cooling capacity.

ることができる。However, according to the manufacturing method of the present invention, it is possible to completely bring them into close contact, so it is no exaggeration to say that the thermal resistance can be eliminated.When the pipe expansion work is completed, as shown in Fig. 2, it is no exaggeration to say that the thermal resistance can be eliminated. In this state, both ends of the heat pipe tube material (6) are sealed with the sealing pieces (8), and a predetermined amount of an evaporative working liquid such as fluorocarbon, ammonia, water, etc. is sealed inside. The heat pipe (9) can be configured as shown in FIG. Since this heat pipe (9) has no thermal resistance at its joint, its thermal efficiency is improved and its cooling characteristics are extremely excellent. As a result, the cooling characteristics of the roll (5) can be improved.

を奏する。In addition, in the above embodiments, the expansion of the Heatvibe tubing is performed by extrusion, but it is also possible to expand the Heatvibe tubing by drawing, or by applying hydraulic pressure inside the Heatvibe tubing without using a tube expansion tool. Alternatively, the pipe may be expanded by applying pressure such as water pressure, and the same effect as in the above embodiment can be obtained.
