There is US Pat. No. 3,179,549 as a conventional vacuum insulation material. This conventional vacuum heat insulating material will be explained with reference to FIGS. 8 and 9.

Since the glass fibers of the above-mentioned prior art are simply laminated randomly inside the container, the glass fibers are in a soft state. If the inside of the container is evacuated while the glass fibers are housed in the container, the glass fibers will be compressed due to the deformation of the container, resulting in a thin vacuum insulation material. Therefore, there is a possibility that the insulation performance of conventional vacuum insulation materials may deteriorate.

The above purpose is to randomly stack and arrange glass fibers in a direction perpendicular to the heat transfer direction in a container made of a thin metal plate having a flat part, and arrange some of the glass fibers in the heat transfer direction. This is achieved by compressing the glass fibers and sealing the inside of the container in a vacuum state.

When the inside of the container is evacuated, the container deforms in the direction of the glass fibers, but since the glass fibers placed inside the container are compressed to a high density, the glass fibers are not compressed by the deformation of the container. As a result, the vacuum insulation material does not become thinner, so that the insulation performance can be improved.

く、プレスおよび溶接等の加工性も良好である。 In the figure, the vacuum insulation material 11 is made by laminating thin glass fibers 15 randomly in a direction perpendicular to the heat transfer direction in a flat container 14 made up of two thin metal plates 12 and 13. , the inside of the container 14 is sealed in a vacuum state. One of the thin metal plates 12 and 13 is formed by drawing and has a flange portion 12a on its periphery, and a drawing hole 12c in a portion of the bottom portion 12b. This thin metal plate 1
The second material is an alloy of iron, nickel, and chromium, an alloy of iron and nickel, or an alloy of iron and chromium. The other thin metal plate 13 is flat and thinner than the metal plate 12. Both metal plates 12 and 13 are made of the same material to facilitate welding of the two. Also, both metal plates 1
By using the alloy material for the metal plates 12 and 13, the thermal conductivity is reduced to a fraction of that of iron, which makes it possible to reduce heat conduction loss through the contact area between the two metal plates 12 and 13. After processing such as baking, the amount of gas generated from the surface and inside becomes very small.
Deterioration of the degree of vacuum can be reduced, and it has excellent corrosion resistance and strength. Even when made into a thin plate, there are no defects such as holes, and workability such as pressing and welding is also good.

を維持することができる。 The glass fiber 15 used does not contain additives such as hardening agents and adhesives. If additives are used, gas will be generated from the additives and the degree of vacuum will deteriorate. The glass fibers 15 are cut into predetermined lengths, dropped into a vacuum-covered duct, sucked in, and stacked randomly.
It can be done easily. By randomly laminating the glass fibers 15, they come into point contact with each other, increasing the contact thermal resistance and improving the heat insulation performance. The randomly laminated glass fibers 15 are compressed by applying pressure from above and below, and then a needle 16 having a hook portion 16a as shown in FIG.
5, a part of the outside of the glass fiber 15 is hooked on the hook part 16a, becomes the fiber 15a for penetration, is arranged in the heat transfer direction, and is randomly laminated with the fiber 15a. Due to the frictional force with the glass fibers, even if the pressure from above and below is removed, the compressed state is maintained, forming a mat shape as shown in FIG. These fibers 15a can be sufficiently maintained in a compressed state if several dozen fibers are sewn per 1 cm2, so if glass fibers 15 , 15a with an outer diameter of about 10 microns are used, the fibers 15a account for a fraction of the total area. The area ratio is extremely small at 3×10 -3 %. Therefore, even if the fibers 15a extend in the same direction as the heat transfer direction, the amount of heat transfer is negligible when viewed from the whole. If the needles 16 are inserted into both sides of the glass fibers 15, the compressed state can be maintained with a small number of fibers 15a.

によつて防止できる。 Next, a method for manufacturing such a vacuum heat insulating material 11 will be explained. A vacuum pipe 17 is hermetically welded to the throttle hole 12c of the throttle metal plate 12. In this case, high-temperature welding such as brazing is used to withstand high-temperature baking treatment in the post-process. Both the drawn metal plate 12 and the flat metal plate 13 are cleaned by degreasing, pickling, etc., and then heated to a high temperature (approximately 400°C) to remove molecules such as impurities adhering to the surface. Apply baking treatment. Further, the mat-shaped glass fiber 15 is also subjected to the same baking treatment. By this baking process, the amount of gas generated within the container 14 can be suppressed. Next, the bottom part 12 of the aperture outer plate 12
After placing the getter 10 in b as shown in Fig. 2,
A mat-shaped glass fiber 15 is arranged, a lid is placed on a flat metal plate 13, and a flange portion 1 of the drawn metal plate 12 is placed.
2a and the outer periphery of the flat metal plate 13 are hermetically welded to form the state shown in FIG. This welding uses resistance welding, electron beam welding, etc. These welding methods are suitable for welding thin-walled materials and can withstand high temperatures during baking, which will be described later. The members thus assembled are further placed in a furnace, and a vacuum is pulled from the vacuum pipe 17 to perform vacuum baking. This makes it possible to exhaust gases caused by impurities and the like that were attached or mixed during assembly. When the target degree of vacuum is reached, a portion of the vacuum pipe 17 is pressurized and cut. When the inside of the container 14 is evacuated, 1
A high pressure of (Kg/cm 2 ) is applied, compressing and deforming the glass fiber 15, but because the glass fiber 15 has a high density, it does not deform as much as before even if the degree of vacuum is increased. , as shown in FIG. 6, the thickness is only slightly reduced. Therefore, the degree of vacuum can be increased and the insulation performance can be greatly improved, and the container 14 will not be cracked. In this case, since the flat metal plate 13 is thinner than the drawn metal plate 12 and is flat, it has flexibility and is easily deformed. This prevents the aperture metal plate 12 from deforming, so if the aperture metal plate 12 is used as a reference when combining, the combination can be performed with high precision. By making the flat metal plate 12 thinner, heat conduction from the drawn metal plate 12 is reduced, and its loss is reduced.
Furthermore, since the glass fibers 15 have a high density, the typical heat transfer dimension of the void portion becomes small, the molecular free path becomes short, and the heat transfer coefficient can be significantly reduced. As a result, the necessary heat insulation performance can be obtained without increasing the degree of vacuum so much that the evacuation time can be shortened. Furthermore, since the glass fiber 15 has a high density, the glass fiber 15
The number of times of contact increases, and the contact thermal resistance increases significantly. This significantly reduces the thermal conductivity of the glass fibers 15. Moreover, the aperture metal plate 12
The radiant heat between the flat metal plate 13 and the glass fiber 15
This can be prevented by

According to the present invention, since the glass fibers are compressed to a high density, the glass fibers are not compressed even if the inside of the container is evacuated and the container is deformed in the direction of the glass fibers. Therefore, since the vacuum insulation material does not become thinner, it is possible to improve the insulation performance.
