[0009] Embodiments of an insulating structure and an insulating structure manufacturing apparatus according to the present disclosure will be described below with reference to the drawings. The present invention is not limited to the embodiments. Furthermore, components in the embodiments described below include those that can be easily replaced by those skilled in the art or those that are substantially the same.

[0010] Fig. 1 is a sectional view showing an example of an insulating structure according to the present embodiment. As shown in Fig. 1, an insulating structure 100 includes a laminate 10. The laminate 10 has a structure in which a plurality of plate bodies 20 are layered.

[0011] Each of the plate bodies 20 includes a substrate 21 and a reinforcing member 22. The plate body 20 has a configuration in which a pair of the substrates 21 and a reinforcing member 22 overlap with each other such that the reinforcing member 22 is sandwiched between the substrates 21. The substrate 21 and the reinforcing member 22 are each formed of a composite material. Examples of the composite material include carbon fiber reinforced plastic (CFRP, CFRTP), glass fiber reinforced plastic (GFRP, GFRTP), aramid fiber reinforced plastic (AFRP, AFRTP), and cellulose nanofiber reinforced plastic (CNFP, CNFTP).

[0012] The substrate 21 has a flat plate shape. The substrate 21 has a rectangular shape, for example. The substrate 21 has a planar portion 21a. In the following description, a direction along the planar portion 21a is referred to as a plane direction.

[0013] The reinforcing element 22 has a plate shape and a plurality of protruding portions 23 that protrude toward the substrate 21. The reinforcing element 22 is supported by the substrate 21 such that an end portion 23a of the protruding portion 23 is in contact with the substrate 21. In a Fig. 1, the reinforcing element 22 has a corrugated structure comprising a plurality of corrugated sections that are continuous in one direction. In the example shown in Fig. 1, a portion corresponding to bulges of the plurality of corrugated portions is the end portion 23a of the projecting portion 23.

[0014] In the laminate 10, the plurality of plate bodies 20 are layered via a spacer 30. The plurality of plate bodies 20 are arranged so that the planar portions 21a of the substrate 21 face each other. The spacer 30 has a configuration in which a plurality of spherical bodies 31 are connected to each other by a connecting member 32. The plurality of plate bodies 20 are in a state where the planar portion 21a of the substrate 21 is in point contact with the spherical body 31. For this reason, a contact area between the plate body 20 and the spacer 30 can be reduced, and heat transfer between the plate body 20 and the spacer 30 can be suppressed. For this reason, an insulating effect is improved.

[0015] An entirety of the laminate 10 is housed in a laminate housing portion 40. The laminate housing portion 40 is formed in a pocket shape using a material such as aluminum or a composite material. The laminate housing portion 40 is sealed in a state where the laminate 10 is housed so that an inside thereof is in a vacuum state. For this reason, in the laminate 10, a space K1 between the substrate 21 and the reinforcing member 22 of a plate body 20 and a space K2 between the substrates 21 facing each other in a laminating direction are in the vacuum state. The spaces K1 and K2 in the vacuum state function as an insulating layer. The facing reinforcing members 22 may be arranged so that the corrugated portions are perpendicular to each other.In the present disclosure, the vacuum state may be a state of a space filled with a gas having a pressure lower than normal atmospheric pressure. As the vacuum state, for example, it is preferable to set a pressure equal to or lower than that of a medium vacuum region (approximately 0.1 Pa or more and lower than 100 Pa). In the present disclosure, for example, instead of the vacuum state, a gas-filled state in which an inside is filled with a gas having lower thermal conductivity than that of air may be used. Here, examples of the gas having lower thermal conductivity than that of air include an argon gas, a krypton gas, or the like.

[0016] The laminate receiving portion 40 can accommodate an adsorbent G that adsorbs a gas generated by the substrate 21 and the reinforcing member 22. Examples of such an adsorbent include materials such as activated carbon, zeolite, and calcium oxide, and alloys of zirconium, titanium, barium, and magnesium. Furthermore, the spacer 30 can contain the adsorbent G. In a case where the adsorbent G is used, the spaces K1 and K2 are formed to be in a vacuum state.

[0017] The insulating structure 100 is manufactured by laminating the plurality of plate bodies 20 via the spacer 30 to form the laminate 10, accommodating the laminate 10 in the laminate accommodating portion 40, and placing the inside of the laminate accommodating portion 40 under vacuum. In this case, it is not necessary to perform fusion or the like on the spacer 30 with respect to each plate body 20, and a position of the spacer 30 is fixed in a state of being sandwiched between the plate bodies 20 by vacuum pressure. For this reason, a manufacturing process of the insulating structure 100 can be simplified. Moreover, when the insulating structure is subjected to a load due to an external force, the spherical body 31 of the spacer 30 can move freely depending on the load. Therefore, stress concentration can be avoided.

[0018] As described above, the insulating structure 100 according to the present embodiment includes the flat plate-shaped substrate 21 and the reinforcing member 22 having a plate shape, has the plurality of protruding portions 23 protruding toward the substrate 21, and is supported by the substrate 21 such that the end portion 23a of the protruding portion 23 is in contact with the substrate 21, wherein the substrate 21 and the reinforcing member 22 are formed of a composite material.

[0019] According to this configuration, since the substrate 21 and the reinforcing member 22 are formed of a composite material, the weight of the insulating structure 100 can be reduced. Furthermore, since the reinforcing member 22 is supported by the substrate 21 such that the end portion 23a of the protruding portion 23 is in contact with the substrate 21, strength can be ensured.

[0020] In the insulating structure 100 according to the present embodiment, the reinforcing member 22 has a corrugated structure. With this configuration, the strength of the insulating structure 100 can be ensured.

[0021] In the insulating structure 100 according to the present embodiment, the plate body 20 is provided in which the pair of substrates 21 and the reinforcing member 22 overlap with each other so that the reinforcing member 22 is sandwiched between the pair of substrates 21. With this configuration, the reinforcing member 22 is sandwiched between the pair of substrates 21, so that the strength can be ensured.

[0022] In the insulation structure 100 according to the present embodiment, the laminate 10 in which the plurality of plate bodies 20 are laminated is provided. With this configuration, the plurality of lightweight plate bodies 20 are laminated, so that the strength can be increased while ensuring weight reduction.

[0023] In the insulating structure 100 according to the present embodiment, the spacer 30 is arranged between the plurality of plate bodies 20 in the laminate 10 in the lamination direction. With this configuration, a space can be secured between the plurality of plate bodies 20. Therefore, heat transfer in the lamination direction of the laminate 10 can be suppressed.

[0024] In the insulating structure 100 according to the present embodiment, the spacer 30 includes the spherical body 31, and the plurality of plate bodies 20 are in a state where the substrates 21 are in point contact with the spherical body 31. With this configuration, the contact area between the plate body 20 and the spacer 30 can be reduced, and heat transfer between the plate body 20 and the spacer 30 can be suppressed. For this reason, an insulating effect is improved.

[0025] In the insulating structure 100 according to the present embodiment, the entirety of the laminate 10 is accommodated in the laminate accommodating portion 40, and the laminate accommodating portion 40 is sealed so that the inside thereof is in a vacuum state. According to this configuration, a vacuum portion can be formed in the space within the laminate 10. Therefore, insulating properties can be further improved.

[0026] In the insulating structure 100 according to the present embodiment, the laminate accommodating portion 40 has a pocket shape. According to this configuration, a step of accommodating the laminate 10 and a step of placing the inside in a vacuum state can be easily performed.

[0027] In the insulating structure 100 according to the present embodiment, the laminate accommodating portion 40 can accommodate the adsorbent G that adsorbs a gas. According to this configuration, the gas generated by the substrate 21 and the reinforcing member 22 can be properly adsorbed.

[0028] Fig. Fig. 2 is a view showing another example of the insulating structure according to the present embodiment. In a Fig. 2, a spacer 30A has a columnar shape. Other configurations are the same as those of the insulating structure 100 shown in Fig. 1. As shown in Fig. 2, the spacer 30A may have a configuration in which a spherical body is not provided.

[0029] Fig. 3 is a view showing another example of the insulating structure according to the present embodiment. Fig. The insulating structure 100B shown in Fig. 3 has a configuration in which a spacer 30B has the plurality of spherical bodies 31 and the spherical bodies 31 are not connected to each other. As shown in Fig. 3, the plurality of spherical bodies 31 may be configured so that they are not connected to each other.

[0030] Fig. 4 is a view showing another example of the insulating structure according to the present embodiment. Fig. The insulating structure 100C shown in FIG. 4 has a configuration in which multiple layers of spacers 30 are provided between the plate bodies 20. For example, a partition plate 33 formed of a composite material is disposed between the layers of the spacer 30. A configuration of the partition plate 33 may be the same as that of the substrate 21, for example.

[0031] Fig. 5 is a view showing another example of the insulating structure according to the present embodiment. Fig. The insulating structure 100D shown in Fig. 5 has a plate body 20D in which a plurality of the reinforcing elements 22 are layered such that the extension directions of the corrugated portions of the corrugated structure intersect. As shown in Fig. 5, a configuration is used in which the corrugated portions of the corrugated structure are arranged at the reinforcing member 22 so as to intersect each other, and the reinforcing members 22 are in direct contact with each other. Accordingly, a path length can be made long, and insulating properties can be improved. Moreover, insulating properties and strength can be further improved by laminating three or more reinforcing members. The lamination can be performed not only perpendicularly but also at an angle of 60°. Furthermore, the plate body 20D may be accommodated in the laminate accommodating portion 40, and the inside of the laminate accommodating portion 40 may be placed under vacuum.

[0032] Fig. 6 is a view showing another example of the insulating structure according to the present embodiment. Fig. The insulating structure 100E shown in FIG. 6 is configured such that a sealing portion 41 seals between the adjacent substrates 21 with the spacer 30 interposed therebetween. The sealing portion 41 seals between the substrates 21, sandwiching the space K2 formed between the plate bodies 20 in the lamination direction, such that the space K2 is in a vacuum state. A material such as a resin material or the same composite material as the substrate 21 can be used as the sealing portion 41.

[0033] The insulating structure 100E is manufactured by laminating the plate bodies 20 to form the laminate 10, then placing a periphery of the laminate 10 under vacuum, and adhering the sealing portion 41 to an end edge of the substrate 21. Since an outer side of the space K2 in the vacuum state is covered with the plate body 20, the space K2 can be protected in this way. Furthermore, compared to a configuration in which the entirety of the laminate 10 is surrounded by the pocket-shaped laminate accommodating portion 40, the vacuum state is less likely to be destroyed due to contact.

[0034] Fig. Fig. 7 is a view showing another example of the insulating structure according to the present embodiment. Fig. The insulating structure 100F shown in FIG. 7 includes a structure including the laminate 10 in which the plurality of plate bodies 20 are laminated, and a structure in which the laminate 10 is not accommodated in the laminate accommodation portion 40. In this way, by using the laminate 10 as the insulating structure 100F, it is possible to achieve weight reduction and cost reduction while ensuring strength of the insulating structure 100F.

[0035] Fig. 8 and Fig. 9 are views showing other examples of the insulating structure according to the present embodiment. Fig. 8 shown insulating structure 100G and one in Fig. The insulating structure 100H shown in Figure 9 has a configuration in which an insulating material 50 is arranged between the plurality of plate bodies 20. The insulating material 50 is a material for reducing heat transfer and is a material that exhibits insulating performance through chemical properties and a physical structure. The insulating material 50 contains a material with low thermal conductivity and no or little heat transfer due to convection and radiation. Examples of such an insulating material 50 include polystyrene foam, urethane foam, and aerogel. Fig. The spacer 30 is arranged in the insulating structure 100G shown in Fig. 8. In the case of Fig. In the insulating structure 100H shown in Figure 9, the spacer 30 is not arranged. Thus, insulating properties can be ensured without the vacuum state by disposing the insulating material 50 between the plurality of plate bodies 20.

[0036] Fig. 10 is a view showing another example of the insulating structure according to the present embodiment. In a Fig. In the insulating structure 100I shown in FIG. 10, a structure of a reinforcing member 22I is different from the corrugated structure. The reinforcing member 22I has a configuration in which protruding portions 23I protruding in opposite directions are formed in a plate-shaped body. The reinforcing member 22I is supported in a state where an end portion 23Ia of the protruding portion 23I is in contact with the substrate 21. As described above, the structure of the reinforcing member 22I is not limited to the corrugated structure, and the reinforcing member 22I can take various shapes as long as the shape includes a protruding portion.

[0037] Fig. 11 is a view showing another example of the insulating structure according to the present embodiment. Fig. The insulating structure 100J shown in FIG. 11 includes, as a laminate receiving portion 40J, plate-shaped portions 42 arranged on both sides of the laminate 10 in the lamination direction, and a first frame-shaped portion 43 that provides the space K2, which is a gap between the plate bodies 20 to be laminated, and that seals between the plate-shaped portions 42 so that the gap is in the vacuum state. The plate-shaped portion 42 is formed of, for example, a metal material such as aluminum. The first frame-shaped portion 43 includes an insertion portion 43a inserted between the plate bodies 20. The plate bodies 20 are laminated with the insertion portion 43a inserted therebetween. The first frame-shaped portion 43 has a penetrating portion 43b penetrating an inside and an outside of the space K2.The penetrating portion 43b is provided so that the space K2 can be vacuumed through the penetrating portion 43b. After vacuuming, the penetrating portion 43b can be closed by a closing portion (not shown).

[0038] The insulating structure 100J can ensure strength through the above configuration. Furthermore, in the event of an external impact, the insulating structure 100J can be easily repaired by simply replacing the plate-shaped portion 42 as needed and performing the vacuum setting again.

[0039] Fig. Fig. 12 is a view showing another example of the insulating structure according to the present embodiment. In a Fig. In the insulating structure 100K shown in FIG. 12, a sealing portion 41K is configured to seal the space K2 for each of the substrates 21 facing each other between the plate bodies 20 to be laminated. The sealing portion 41K is formed, for example, from a resin material or a composite material. The sealing portion 41K can be sealed, for example, by fusing or welding. In this configuration, the sealing portion 41K formed from a composite material different from those of the substrate 21 and the reinforcing member 22 is provided so that the sealing portion 41K can be easily fused.

[0040] Fig. 13 is a view showing another example of the insulating structure according to the present embodiment. In a Fig. In the insulating structure 100L shown in FIG. 13, a configuration is used in which spherical portions 21b are provided at corner portions of the rectangular substrate 21. Since the corner portions of the substrate 21 have a rounded shape in this way, for example, when the substrate 21 is accommodated in the laminate accommodating portion 40, it is possible to prevent the laminate accommodating portion 40 from being damaged.

[0041] Fig. 14 is a view showing another example of the insulating structure according to the present embodiment. Fig. The insulating structure 100M shown in Figure 14 has a configuration in which another insulating material 50 is bonded to the plate body 20. For example, an insulating layer 51 made of polystyrene foam or urethane foam, a vacuum insulating layer 52, or the like can be used as the insulating material 50. With this configuration, the insulating structure 100M can be narrowed.

[0042] Fig. 15 is a view showing another example of the insulating structure according to the present embodiment. In a Fig. In the insulating structure 100N shown in FIG. 15, a protective layer 60 is provided between the laminate receiving portion 40 and the laminate 10. By providing the protective layer 60, it is possible to prevent the laminate receiving portion 40 from being damaged when the entire insulating structure 100N is deformed, such as when the entire insulating structure 100N is bent or the like. Furthermore, by using a material having high insulating properties as the protective layer 60, insulating properties can be improved.

[0043] Fig. 16 is a view showing another example of the insulating structure according to the present embodiment. Fig. The insulating structure 100O shown in FIG. 16 includes a joined body 70 in which the laminates 10 are joined to each other in the in-plane direction. The laminate 10 has a fusion portion 44, in which the facing substrates 21 are fused to each other, as the sealing portion at an end edge portion of the facing substrates 21 of the plate bodies 20 to be laminated. The fusion portion 44 is provided in a state where an end portion thereof protrudes to an outside in the in-plane direction with respect to the substrate 21. The joined body 70 is joined in the in-plane direction so that the fusion portions 44 overlap each other. The fusion portions 44 are formed so as to be crossed in the lamination direction at the time of joining the joined body 70.With this configuration, it is possible to suppress heat introduced from a bonded portion in each of the laminates 10.

[0044] Fig. 17 is a view showing an example of an insulating structure manufacturing apparatus according to the present embodiment. As shown in Fig. As shown in Fig. 17, an insulating structure manufacturing apparatus 200 includes a holding section 110 and an end-edge fusing section 120. The holding section 110 holds two plate bodies 20 so that the substrates 21 face each other. The end-edge fusing section 120 includes heating sections 121 and 122 and a driving section 123 that drives the heating sections 121 and 122. The heating sections 121 and 122 apply heat to the substrates 21 facing each other to fuse the substrates 21. The heating section 121 includes a step section 121a that bends one substrate 21 toward one side of the other substrate 21. The driving section 123 moves the heating sections 121 and 122 to clamp the substrates 21 facing each other via the heating sections 121 and 122.

[0045] When manufacturing the insulating structure 100O, first, the two plate bodies 20 are held by the holding section 110. In this state, after the heating sections 121 and 122 are brought into a heated state, the driving section 123 drives the heating sections 121 and 122 to clamp the substrates 21 facing each other of the two plate bodies 20. In this way, the insulating structure 100O is manufactured, which has the fusing section 44 in which one substrate 21 of the substrates 21 facing each other is fused in a curved state to the other substrate 21 side. In the insulating structure 100O, the fusion portion 44 is formed in a state where one of the substrates 21 facing each other is curved toward the other substrate 21 side.Therefore, when the insulating structures 100O are connected to each other in the plane direction, a configuration in which the fusion portions 44 are crossed in the lamination direction can be easily formed.

[0046] Furthermore, the insulating structure manufacturing apparatus 200 includes the holding section 110 that holds two plate bodies 20 in which the reinforcing member 22 is provided so as to be sandwiched between the pair of flat plate-shaped substrates 21 so that the substrates 21 face each other, the reinforcing member 22 being formed of a composite material, having a plate shape including a plurality of protruding portions 23 protruding toward the substrate 21, and being supported by the substrate 21 so that the end portion 23a of the protruding portion 23 is in contact with the substrate 21, the substrate 21 being formed of a composite material, and the end edge fusing section 120 that fuses end edges of the substrates 21 facing each other of the two plate bodies 20 held by the holding section 110 in the plane direction.Therefore, the insulating structure 100O having the fusion portion 44 can be efficiently manufactured.

[0047] Fig. 18 is a view showing another example of the insulating structure according to the present embodiment. Fig. The insulating structure 100P shown in Figure 18 includes a bonded body 70P in which the laminates 10 are bonded together in the plane direction. The bonded body 70P has a fusion portion 45, in which the facing substrates 21 are fused together, as the sealing portion at an end edge portion of the facing substrates 21 of the plate bodies 20 to be laminated. Fig. In the configuration shown in FIG. 18, an end portion of the fusion portion 45 is provided on an inner side in the plane direction with respect to the substrate 21. In the joined body 70P, a plurality of the laminates 10 are joined in the plane direction via a joining member 80 that seals the end portion of the fusion portion 45. Examples of the joining member 80 include rubber or the like. In this way, the joined body 70P is formed in a state where a portion where the fusion portion 45 is formed is sealed by the joining member 80. Therefore, heat introduced from the joined portion can be suppressed in each of the laminates 10.

[0048] Fig. 19 is a view showing another example of the insulating structure manufacturing apparatus according to the present embodiment. As shown in Fig. As shown in Figure 19, an insulating structure manufacturing apparatus 200P includes a holding section 210 and an end-edge fusing section 220. The holding section 210 holds two plate bodies 20 so that the substrates 21 face each other. The end-edge fusing section 220 includes a heating section 221 and a driving section 223 that drives the heating section 221. The heating section 221 applies heat to the substrates 21 facing each other to fuse the substrates 21. The heating section 221 includes a step section 221a that clamps the facing substrates 21. The driving section 223 moves the heating section 221 to clamp the substrates 21 facing each other via the step section 221a of the heating section 221.

[0049] Fig. 20 and Fig. 21 are views showing other examples of the insulating structure according to the present embodiment. In a case where the insulating structure is formed by using the Fig. 17 and the insulating structure manufacturing device 200 shown in Fig. 19, for example, three sides or four sides of the rectangular laminate 10 may be sealed in the atmosphere, and then a remaining portion may be sealed in a vacuum chamber. In this case, as shown in Fig. 21, a slit-shaped penetrating portion 35a is formed in a part of a frame-shaped portion 35 in which the frame-shaped portion 35 is bonded to the substrate 21 along an outer peripheral portion of the substrate 21 by fusing, welding, or using a hot-melt adhesive. From this state, after an inside of the vacuum chamber is placed under vacuum, the penetrating portion 35a is closed by a closing portion 35b. Accordingly, the vacuum state can be easily formed.

[0050] Fig. 22 is a view showing another example of the insulating structure according to the present embodiment. Fig.The insulating structure 100Q shown in FIG. 22 includes a joined body 70Q in which the laminates 10 are joined to each other in the plane direction. In the joined body 70Q, the plurality of laminates 10 are joined in the plane direction via a joining member 80Q that seals the end portion of the fusion portion 45. The joining member 80Q is disposed, for example, within a portion sandwiched by the substrates 21. In this way, the joined body 70Q is formed in a state where a portion where the fusion portion 45 is formed is sealed by the joining member 80Q. Therefore, heat introduced from the joined portion can be suppressed in each of the laminates 10.

[0051] An insulating structure according to a first aspect includes a flat plate-shaped substrate 21 and a reinforcing member 22, 22I having a plate shape, a plurality of protruding portions 23, 23I protruding toward the substrate 21, and supported by the substrate 21 such that an end portion of the protruding portion 23, 23I contacts the substrate 21, wherein the substrate 21 and the reinforcing member 22, 22I are formed of a composite material. With this configuration, since the substrate 21 and the reinforcing member 22 are formed of a composite material, the weight of the insulating structure 100 can be reduced. Furthermore, since the reinforcing member 22 is supported by the substrate 21 such that the end portion 23a of the protruding portion 23 contacts the substrate 21, strength can be ensured.

[0052] An insulating structure according to a second aspect is the insulating structure according to the first aspect, wherein the reinforcing member 22, 22I has a corrugated structure. With this configuration, the strength of the insulating structure can be ensured.
