Field of the Invention The present invention relates to a high heat load heat receiving plate such as a diverter plate for a fusion device. 2. Description of the Related Art A conventional high heat load heat receiving plate such as a diverter plate will be described with reference to FIGS. Note that, of the elements shown here, those constituting the tokamak fusion apparatus other than the plasma vacuum vessel are omitted. FIG. 6 shows a poloidal cross section of a tokamak-type fusion device. A separatrix line 2 which is a contour line of a magnetic field which determines the shape of a plasma 1 is connected to a heat receiving plate outside an intersection (round point) 3. Diverter plate 4. A part of the plasma having high energy is drawn out along the separatrix line 2 and enters the diverter plate 4. In addition, in FIG.
Is a plasma container. Thus, the heat load distribution of the plasma 1 drawn along the separatrix line 2 is
As shown in FIG. 7, a Gaussian distribution is shown around the separatrix line 2. Since the heat load is extremely high on the separatrix wire, the heat receiving plate 4 is arranged at an angle to reduce the heat load per unit area. [0004] As shown in FIGS. 8 and 9, the heat receiving plate 4 is formed by joining a cooling pipe 7 to one side of a cooling substrate 6 and joining an armature 8 to the other side. Among these members, a material such as copper having excellent heat conduction is preferably used for the cooling substrate 6 and the cooling pipe 7. On the other hand, the armature 8 is used for suppressing mixing of impurities into the plasma 1. Graphite having a low atomic weight is used. When the heat receiving plate 4 is exposed to a thermal load, a large temperature difference occurs between the surface 9 of the armature 7 having a large thermal load and the inner surface 10 of the cold cooling pipe 7. Is attached. For this reason, an excessive thermal stress is generated, and a minute crack is generated in the joint surface between the members, and the armature tile 8
However, there occurs a problem such as peeling off from the cooling substrate 6. [0006] The armature 8 is damaged by sputtering by plasma particles. When the temperature exceeds a certain threshold, the amount of wear increases rapidly, and the life of the armature 8 is significantly impaired. To improve the cooling performance and suppress the temperature rise of the armature 8 is an effective countermeasure to solve the problem such as separation, but for that purpose, the flow rate of the cooling water passing through the cooling pipe 7 is increased. Must. However, increasing the flow velocity more than necessary results in an increase in pressure loss, and cannot be made faster than a certain degree. If there is a limit to increasing the flow velocity, the required thermal conductivity cannot be obtained,
Cooling performance cannot be improved. [0008] In view of the above, FIG.
The spiral partition plate 11 is provided together with the rod 12 in the cooling pipe 7 in the portion where the heat load is high as shown in FIG. In this method, the flow passage area is clearly reduced, and the cooling water is caused to flow while swirling along the partition plate 11, whereby the heat radiation effect can be enhanced. However, in order to provide the spiral partition plate 11 together with the rod 12 in the cooling pipe 7, it is necessary to overcome some technical problems. For example, it is not easy to obtain a partition plate 11 having an optimum bending angle or an optimum pitch, and it is difficult to make the cooling pipe 7 have a desired cooling performance. An object of the present invention is to provide a method of manufacturing a cooling pipe for a high heat load heat receiving plate, which can be easily manufactured and has higher cooling performance. [0011] In order to achieve the above object, a method of the present invention is to heat a predetermined section of a metal tape to maintain a predetermined temperature while twisting the heating section to form a spiral. It is molded into a shape, and then a cooling medium is sent to the molding part to quench it.
Quenching , and further repeating the above-mentioned twist forming and cooling steps to form a spiral structure having a continuous spiral shape, and then inserting the spiral structure into the cooling pipe and subjecting the cooling pipe to cold drawing to tape the spiral structure The edge is brought into close contact with the inner surface of the cooling pipe and joined. As the material of the metal tape that can withstand the dynamic pressure of the cooling water passing through the cooling pipe, stainless steel having mechanical strength and excellent corrosion resistance is preferable. However, it is difficult to twist a metal tape made of stainless steel spirally at a predetermined pitch at room temperature (or cold). In general, in the case of stainless steel, it is possible to process to a predetermined length at room temperature with a twist pitch of 3 to 4 times the tape width. However, when the twist pitch of the metal tape is three times or less the tape width as in the present invention, the metal tape having a predetermined pitch or a predetermined length must be heated and softened without twisting. Difficult to get. Further, if the entire metal tape is heated and twisted in a softened state, a stable metal tape with a constant pitch cannot be obtained due to variations in strength or hardness of the metal tape. Therefore, in the present invention, only a predetermined section to be subjected to twisting is heated, and immediately after being formed to a predetermined pitch, cooling is performed by flowing, for example, cooling water or the like to the portion where the twisting has been completed, thereby cooling the metal tape. By increasing the hardness and strength, the portion once subjected to the twist forming is prevented from undergoing the twisting again. By doing so, a helical structure twisted at a predetermined pitch can be obtained. By the way, since such a spiral structure is twisted to a length of several meters, it is necessary to continuously perform the twisting in order to increase the productivity. Therefore, the efficiency is low in natural cooling or the like, and the hardness and strength of the metal tape cannot be expected to be improved due to a slight quenching effect obtained by rapid cooling. Therefore, it is preferable to use a dedicated twisting machine. Next, the spiral structure is inserted into a cooling pipe and subjected to cold drawing to finish it to a predetermined size. Since this cold drawing process results in a predetermined outer diameter and inner diameter, it is particularly important to specify a drawing die. Therefore, since the inner diameter of the drawing die is equal to the outer diameter of the cooling pipe after drawing, the drawing die must be selected according to the final outer diameter of the cooling pipe. On the other hand, in cold drawing, the inner diameter of the cooling pipe and the width of the metal tape constituting the spiral structure are 1 to 1.
There is an interval of about 2mm. The outer diameter of the cooling pipe is reduced so that the interval becomes zero, and the metal tape is squeezed until the edge of the metal tape comes into close contact with the inner surface of the cooling pipe or is bitten. Thus, the spiral structure and the cooling pipe are firmly fixed, and can withstand the dynamic pressure of the cooling water. Although the metal tape is in close contact with the inner surface of the cooling pipe or slightly bites there, the function of the cooling pipe is not impaired. Thus, according to the manufacturing method of the present invention, the cooling water can be caused to flow while swirling along the helical structure, and the stirring action is more effectively generated, so that the thermal conductivity can be greatly improved. It is. Further, in order to appropriately maintain the cooling effect, even when the torsion angle or the torsion pitch is changed, it can be easily coped with only by changing the processing conditions in the torsion forming step.
Easy to manufacture. Embodiments of the present invention will be described below with reference to the drawings. In FIG. 1, a metal tape 21 made of, for example, stainless steel is held on a rotary plate Rt provided at one end through a guide plate Gi of a twisting machine that extends one end to twist the work. Bed Bd for twisting machine
Is provided with a heater Ht and a cooler Co supported by an arm Am extending from a carriage Cr that carries a guide board Gi along the same, so that the flame 22 and the cold water 23 are applied to the respective workpieces toward the work. I have. The metal tape 21 is formed by using the above-mentioned twisting machine.
Is performed as follows. First, a flame 22 such as acetylene gas is applied to the metal tape 21 from a heater Ht for a certain section, and the temperature of the section is raised to about 800.
Hold at ~ 1000 ° C. In this state, the turntable Rt is rotated counterclockwise while the carriage Cr is moved toward the turntable Rt. By this rotation, the metal tape 21 held at a high temperature is twisted, and the flat metal tape takes a spiral shape. Next, the formed part is cooled using cold water 23 supplied from a cooler Co provided side by side with the heater Ht. Further, the above steps are repeated to obtain a spiral structure 24 having a continuous spiral shape as shown in FIG. For example, in the embodiment, the relationship between the tape width W and the pitch P is 1: 2 in the spiral structure 24 after being formed.
By changing the number of rotations and the feed speed of the guide board Gi, it is possible to form a free shape. As described above, the spiral structure 24 having a desired twist pitch can be obtained by repeating the twist forming while maintaining the high temperature and the subsequent cooling step. Next, the spiral structure 24 is inserted into the cooling pipe 7 as shown in FIG. At this time, a gap of about 1 to 2 mm is provided in advance between the outer surface of the spiral structure 24 and the inner surface of the cooling pipe 7 to facilitate insertion. Next, the spiral structure 24 and the cooling pipe 7 are subjected to cold drawing shown in FIG. This cold drawing step is performed using a drawing die De to reduce the outer diameter of the cooling pipe 7 to finish it to a predetermined diameter. At this time, the tape edge of the spiral structure 24 comes into close contact with the inner surface of the cooling pipe 7 so that the gap between them becomes zero, and the spiral structure 24 is joined there. A state in which the outer surface of the spiral structure 24 is in close contact with the inner surface of the cooling pipe 7 is shown in FIG. In this case, a part of the metal tape may be slightly cut into the inner surface of the cooling pipe 7 to ensure the close contact. In the cooling pipe 7 of this embodiment in which the flow path is formed by using the spiral structure 24, the cooling water can be caused to flow while swirling along the spiral structure 24, and the stirring action can be further improved. Since it occurs effectively, it is possible to greatly improve the thermal conductivity. In order to properly maintain this cooling effect,
Even when the torsion angle or torsion pitch of the spiral structure 24 is changed, it can be easily coped with only by changing the processing conditions in the torsion forming step, and the manufacture is easy. Further, the spiral structure 24 and the cooling pipe 7 can be easily joined to each other by bringing the cooling pipe 7 into close contact with each other by a drawing process, which is extremely easy to manufacture. As is apparent from the above description, according to the present invention, a predetermined section of a metal tape is heated and maintained at a predetermined temperature, and the heated section is twisted to form a spiral shape.
Thereafter, quenching by quenching sends a cooling medium to the molding unit and <br/>, and the helical structure further repeated torsional formed form Contact and the cooling step, by inserting a cooling tube, a cooling tube since as applied to the cold drawing, can be manufactured to desired flow path high heat load bearing thermal plate cooling tube equipped with the easy, moreover,
It is possible to provide higher cooling performance.
