軟らかいため。Hereinafter, one embodiment of the present invention will be described based on FIGS. 1 to 4. Fig. 1 is a vertical sectional view of the main part showing the state of the heat pipe material before expansion; Figs. 2 and 8 are longitudinal sectional views and front views of the main part showing the state of the heat pipe material after expansion; The figure is a longitudinal sectional view showing the heat pipe after it is formed. First, insert a bottom hole (5a) along the axial direction in the hollow row A/ (6).
are formed substantially concentrically in the circumferential direction, and row A/ (
Insert the beat pipe material (6) having a smaller diameter than the diameter of the bottom hole (δa) into the bottom hole (5a) of s).Then, expand the heat pipe material (6).Heat pipe material (6)
) inside one end side by pressing the tube expansion tool (7).
Push the pipe material (6) toward the other end while expanding it. By the way, for example, the roll (6) is made of iron, and the pipe material (6) is made of copper. Therefore, copper is softer than iron.

穴（５ａ）に強固に密着して結合され１両者間の結合力

なり１両者間の熱抵抗を著しく低減することができる。When the heat pipe material (6) is expanded, the outer surface of the heat pipe material (6) is crushed and tightly connected to the bottom hole (5a) of the roll (5), thereby increasing the bonding force between the two. As the size increases, the adhesion is also very good, and the thermal resistance between the two can be significantly reduced.
なぜならば、底付穴（５ａ）にヒートパイプを挿着する
ことが一般的に考えられるが。This is because it is generally considered that a heat pipe is inserted into the bottom hole (5a).

る例えば７０ン、アンモニア。For fixation and adhesion between the heat pipe and the bottom hole, an adhesive is interposed between the two, but in this case, the required adhesion strength can be met, but the adhesion between the two cannot be completely maintained. It cannot be made into a one-piece structure, the adhesive has air bubbles, and it is extremely difficult to fill the adhesive completely without any gaps between the two, resulting in high thermal resistance and reduced cooling capacity. This will cause a problem that will result in restrictions. However, it is no exaggeration to say that according to the manufacturing method of the present invention, it is possible to completely bring the two parts into close contact with each other, so that thermal resistance can be eliminated. When the pipe expansion work as described above is completed, the result will be as shown in Fig. 2, and in this state, the open end side of the bottom hole (5a) of the heat pipe tube material (6) is sealed with the sealing piece (8). For example, 70 liters of ammonia, which also has evaporative properties inside.
水等の作動液体を所定量封入すると、第４図に示す如く
ヒートパイプ（９）を構成することができる。By filling a predetermined amount of a working liquid such as water, a heat pipe (9) can be constructed as shown in FIG.
このヒートパイプ（９）はその結合部での熱抵抗が無い

優れたものとなる。その結果、ロール（５）の冷却特性
の向上を図ることができる。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.
又、上記実施例ではヒートパイプ管材の拡管は押出拡管

拡管工具を使用しないでヒートパイプ管材内に油圧・水
圧等の圧力をかけて拡管させるようにしてもよく、上記
実施例と同様の効果を奏する。It is also possible to expand the heat pipe by applying pressure such as hydraulic pressure or water pressure inside the heat pipe tube material without using a tube expansion tool, and the same effect as in the above embodiment can be obtained.
