不発明は加熱源よりの急激な熱入射を安全且つ確実に受

そのような配置が困難で゛あった。Conventionally, a device as shown in FIGS. 1 and 2 has been used as a heat receiving device that receives this type of high-energy beam heat. In these Figures 1, 1 is a heat receiving plate;
2 is a cooling pipe, 6 is an incident heat ray or beam, and the second
In the figure, 6 is an incident heat ray or beam, 4 is a fin cooling pipe, and 5 is a header. In the apparatus shown in FIG. 1, the heat receiving plate 1 is arranged in a V-shape or as a single plate, and is used by reducing the thermal load on the surface of the heat receiving plate by reducing the incident angle of the heat rays. However, since this device heats only the surface of the heat receiving plate 1, the temperature difference between the front and back of the heat receiving plate 1 that receives heat and the areas that do not receive heat becomes large. There was a drawback that a large thermal stress exceeding the stress was generated and the heat receiving plate 1 was easily destroyed. The axis shows the incident heat flux, and the horizontal axis shows its distribution.As shown in Figure 4, when the incident heat flux is not uniform, the slope of the heat receiving surface is made thicker in areas where the incident heat flux is high, and the heat flux It is desirable to reduce the inclination in the lower part of the heat receiving plate from the viewpoint of uniforming the thermal load on the heat receiving plate and downsizing the apparatus, but such an arrangement is difficult in the apparatus shown in FIG.

。On the other hand, in the device shown in FIG. 2, the fin cooling pipes 4 are arranged in parallel between the headers 5 to form a heat receiving plate, with the cooling pipe section facing the heat source and the fins 4a facing the cooling pipe when viewed from the heat source. It is located at the back. In this example, since the fins 4a of the finned cooling pipe 4 also receive heat, the fins located in front of the heat rays have the advantage that the γF'lA degree difference between the front and back of the cooling pipe 40 is small, and there is a It has the advantage of not generating thermal stress due to temperature differences on angular force surfaces. However, in a device that hangs from the inside, in the fin cooling tube located at the rear of the heat source (the center tube in Figure 6), the fin part will be in the shadow of the fin of the front tube, resulting in a large temperature difference between the front and back sides. The axial thermal expansion of the finned cooling tube during heat input is restricted by the header 5, resulting in large thermal stress, and the accumulation of small plastic deformations during long-term use causes the finned cooling tube to deteriorate. The disadvantage was that the pinch of the arrangement changed, and as a result, gaps were created between the fins, through which the incident heat rays and beams leaked.

The cooling pipe 10 is provided with a plurality of cooling pipes such that the cooling pipe 10b faces the heat source and the fins are arranged on the back side of the cooling pipe when viewed from the heat source.
are arranged so as to overlap each other to constitute a heat receiving IMr. In Fig. 5, B is the width dimension of the heat receiver 1111,
Each of the finned cooling pipes 5 is guided to a cooling water header 7, and the heat receiving surface is cooled by flowing a refrigerant through the cooling water header 7. In the heat receiving section having such a structure, as shown in FIG. By setting a large value, the temperature gradient that occurs between the heat receiving surface of the rear fin cooling pipe 10 and its back surface can be made as small as in the front fin cooling pipe, and the thermal stress can also be reduced. The lifespan of the product can be extended.

力を従来のものより非常に小さくすることができる。Furthermore, if the heat receiving section is divided into two parts as shown in Fig. 5, by bending the cooling pipes 10 of each finima 1, the optimum distribution of incident heat flux corresponding to the inclined angle of each part of the heat receiving section can be achieved. Since it is easy to set the value to , this has the advantage of reducing the thermal stress in the axial direction of the fin cooling tube 10, and is also effective in making the heat receiving device a /J type. When a tube receives heat, the difference in humidity between the front and back is small, so it expands mainly in the axial direction of the tube. Therefore, as shown in Fig. 5, if the cooling pipe in the part between the heat receiving part 8 and the cooling header 7 is bent into a U-shape and the displacement due to thermal expansion is absorbed by the spring effect of this part, the heat generated in the axial direction of the pipe can be reduced. The stress can be made much smaller than in the conventional case.

に拘束ずろため、同冷却管の受熱部の裏側に第6図に示
す如き支持連結金具6を取イ」ける。In order to mechanically restrain the gap between the fin cooling tubes arranged in parallel, a support connecting fitting 6 as shown in FIG. 6 is provided on the back side of the heat receiving section of the cooling tubes.

って熱膨張が拘束され熱応力が増大することはな見・。This metal fitting restricts only the distance between adjacent fins, but does not restrict displacement in the 11+ direction at all, nor does it directly restrict displacement between both adjacent fins and the distant blue. At this time, since the support metal fitting 6 has no restraining force at all against the deformation of the tube in the axial direction, removing the support metal fitting 6 does not restrict thermal expansion and increase thermal stress. .

に満足しており、高熱流束の入射に対し熱衝撃が小さく
すき間の生じない受熱装置を作ることができる。The deformation of the force surface −\ in the unilateral direction other than the axial direction is minute, and by appropriately setting and shifting the play between the support metal 6 and the cooling pipe, the deformation caused by the thermal rifle of − times is not restrained, but the slight heat Pinch changes or cracks in the tube arrangement (occurring as a result of deformation stacking) can be prevented. The heat-receiving section in which the finned cooling pipes are connected by the support connecting fittings described above simultaneously satisfies the two contradictory requirements of ensuring the overlap of adjacent fins without restricting thermal deformation of the cooling pipes alone. Therefore, it is possible to create a heat receiving device with small thermal shock and no gaps when a high heat flux is incident.
