[0049] As Figures 1 to 11 shown, Figure 4 and 7 in Figure A represents the thickness direction of the flexible housing 10, Figure 8In the B direction, it represents the length direction of the flexible housing 10, and in the C direction, it represents the width direction of the flexible housing 10. In the first aspect of the present utility model, a heat insulation board 100 is proposed, which includes a flexible housing 10 and a plurality of core materials 20. The flexible housing 10 has a plate-shaped structure. A plurality of installation cavities 11 are defined inside the flexible housing 10. The installation cavities 11 are not communicated with each other, and the projections of the installation cavities 11 in the thickness direction of the flexible housing 10 do not overlap. Along the thickness direction of the flexible housing 10, at least one first groove 13 is formed by partial depression on one side of the flexible housing 10. Each installation cavity 11 is filled with a core material 20. Among them, some of the first grooves 13 are located between two adjacent installation cavities 11, and along the extending direction of the first groove 13, at least one end of the first groove 13 is located at the edge of the flexible housing 10, and the heat insulation board 100 can be bent at the first groove 13.

[0050] It can be understood that the flexible housing 10 can be formed by combining two coated films. That is, a flexible coated film is provided with a plurality of pits through a vacuum packaging machine 101 mold. The pits are part of the installation cavities 11. Then, the vacuum packaging machine 101 arranges another flexible coated film opposite to it and heat-seals and connects them to enclose the pits into the installation cavities 11 in a closed state. The plurality of installation cavities 11 are independent of each other. A partial depression between two adjacent installation cavities 11 forms a first groove 13 segment. When the number of installation cavities 11 is more than four, the number of first groove 13 segments is also more than two. The first groove 13 is formed by connecting each first groove 13 segment, and the space between two adjacent first groove 13 segments is also in a depressed state. The flexible housing 10 can also be composed of an integrally formed thermoplastic outer shell, and the integrally formed flexible housing 10 is formed by injection molding or blow molding process, and a plurality of independent installation cavities 11 are defined inside it. The core material 20 is filled in the installation cavities 11 for heat insulation. The coplanar arrangement of the installation cavities 11 means that a plurality of installation cavities 11 are located on the same plane, that is, one end of the plurality of installation cavities 11 in the thickness direction of the flexible housing 10 can be located on the same plane, so that the overall heat insulation board 100 is substantially in a flat plate-shaped structure, which is convenient for installing the heat insulation board 100 on the wall surface of the cavity of the refrigeration equipment.

[0051] Specifically, the extending direction of the first groove 13 is determined by the distribution of the installation cavities 11 on the flexible housing 10. When a plurality of installation cavities 11 are arranged in sequence along one direction, the flexible housing 10 is in the shape of a long strip plate. A part of the first groove 13 is formed between two adjacent installation cavities 11, and both ends of the first groove 13 extend to two opposite edges of the flexible housing 10 respectively, so that the thickness at the first groove 13 is relatively thin, enabling the heat insulation board 100 to be bent at the first groove 13. The bending direction can be the direction in which the installation cavities 11 on both sides of the first groove 13 approach each other, or the direction in which the installation cavities 11 on both sides of the first groove 13 move away from each other. The installation cavities 11 can also be arranged in a rectangular array. At this time, the first groove 13 is formed between two adjacent columns of installation cavities 11, and the first groove 13 is also formed between two adjacent rows of installation cavities 11. The first groove 13 located between two adjacent columns of installation cavities 11 intersects and communicates with the first groove 13 located between two adjacent rows of installation cavities 11. The first groove 13 is also provided with multiple rows and multiple columns and is arranged in a grid pattern. When in use, the user can bend the heat insulation board 100 at any row or any column of the first groove 13 according to actual needs, so that the heat insulation board 100 is adapted to the actual use environment. And each installation cavity 11 is independently arranged. When the installation cavity 11 is a vacuum cavity, when one installation cavity 11 is damaged, it does not affect the use of other installation cavities 11, and the reliability is better.

[0052] In addition, when the flexible housing 10 is composed of a film laminate, the film laminate mainly includes a heat insulation layer, a gas barrier layer, and a heat seal layer arranged in a stacked manner. Among them, the material of the heat seal layer is selected from any one or a combination of two of modified polyamide, polyetherimide, polyimide, polyphenylene sulfide, polyether ether ketone, polyamideimide, polyarylene sulfone, polyethersulfone, and polysulfone; the material of the gas barrier layer is selected from any one of aluminum foil, copper foil, and silver foil. The material of the heat insulation layer is selected from any one or a combination of two of polyimide, polyether ether ketone, polyphenylene sulfide, polytetrafluoroethylene, liquid crystal polymer, polyamide, polyetherimide, polyamideimide, polyarylene sulfone, polyethersulfone, and polysulfone. The edges of two relatively arranged film laminates can be heat-sealed and connected to seal the internal installation cavity 11. The core material 20 can be selected as a particulate core material 20, a foam core material 20, a fiber core material 20, and a composite core material 20 according to actual needs.

[0053] The heat insulation board 100 proposed in the first aspect of the present invention has a plate-shaped structure. A plurality of installation cavities 11 are formed inside the flexible housing 10. The plurality of installation cavities 11 are arranged coplanarly. The installation cavities 11 are filled with a core material 20 for heat insulation. A first groove 13 facilitating bending is also provided on the flexible housing 10. The first groove 13 passes through a part between two adjacent installation cavities 11, and at least one end of the first groove 13 is located at the edge of the flexible housing 10, enabling the user to bend the heat insulation board 100 at the first groove 13 according to actual needs to adapt to the use environment of the heat insulation board 100.

[0054] In some embodiments of the present utility model, the flexible housing 10 includes a first film layer 12 and a second film layer 14 which are oppositely arranged. The edge of the first film layer 12 is connected to the second film layer 14, and the part of the first film layer 12 located between two adjacent core materials 20 is connected to the second film layer 14. A plurality of installation cavities 11 are defined between the first film layer 12 and the second film layer 14. Along the thickness direction of the flexible housing 10, at least one first groove 13 is formed by partial depression on one side of the first film layer 12.

[0055] It can be understood that the shapes of the first film layer 12 and the second film layer 14 are selected according to the shape required for the heat insulation board 100. For example, when the heat insulation board 100 is a rectangular plate, the first film layer 12 and the second film layer 14 are also rectangular; when the heat insulation board 100 is circular, the first film layer 12 and the second film layer 14 are also circular. During production, the lower partition plate 32 of the vacuum packaging machine 101 can be designed into a waffle-like structure with a plurality of groove grids 31. Place the first film layer 12 on the lower partition plate 32, then place the core material 20 on the first film layer 12, and align the position of the core material 20 with the groove grids 31. Then place the second film layer 14 on the side of the core material 20 facing away from the first film layer 12. Control the upper partition plate 30 of the vacuum packaging machine 101 to lower and press the first film layer 12 and the second film layer 14. Press and heat-seal the edges of the first film layer 12 and the second film layer 14, and leave a section at the edge as an opening for vacuum pumping. Finally, pump the air between the first film layer 12 and the second film layer 14 to make the first film layer 12 fit with the second film layer 14, and the installation cavities 11 are in a vacuum state and independent of each other. Finally, heat-seal the remaining opening to complete the production. In addition, the unfolded area of the first film layer 12 can be equal to the unfolded area of the second film layer 14, so that the first film layer 12 and the second film layer 14 can be processed simultaneously, saving cost and time. Or the unfolded area of the first film layer 12 is larger than the unfolded area of the second film layer 14, so that when the first film layer 12 forms a plurality of pits constituting the installation cavities 11 under the pressing of the vacuum packaging machine 101, the edge of the first film layer 12 can be aligned with the edge of the second film layer 14, improving the aesthetics and processability during heat-sealing, and improving the heat-sealing efficiency.

[0056] In some embodiments of the present utility model, the surface area of the first film layer 12 is larger than the surface area of the second film layer 14, and the edge of the first film layer 12 is connected to the edge of the second film layer 14.

[0057] It can be understood that the surface area of the first film 12 is the unfolded area of the first film 12, and the surface area of the second film 14 is the unfolded area of the second film 14. The unfolded area of the first film 12 is larger than that of the second film 14. When the first film 12 is pressed by the vacuum packaging machine 101 to form a plurality of pits constituting the installation cavity 11, the area enclosed by the outer contour of the first film 12 will shrink. To make the edge of the first film 12 align with the edge of the second film 14, the unfolded area of the first film 12 before packaging can be set to be larger than that of the second film 14 before packaging, so that the outer contour of the first film 12 aligns with the outer contour of the second film 14 after being pressed by the vacuum packaging machine 101, thereby improving the aesthetics of the heat insulation plate 100 and the processability during heat sealing, and improving the heat sealing efficiency.

[0058] In some embodiments of the present invention, a partial number of the first grooves 13 extend along the length direction of the flexible housing 10;

[0059] And / or, a partial number of the first grooves 13 extend along the width direction of the flexible housing 10.

[0060] It can be understood that at least a partial number of the first grooves 13 can extend along the length direction of the flexible housing 10, that is, the first grooves 13 are in a straight groove structure. At this time, multiple columns of the first grooves 13 can be arranged along the width direction of the flexible housing 10, and the first grooves 13 are arranged in parallel at intervals, so that the user can bend the heat insulation plate 100 at different first grooves 13 according to actual needs to adapt to the use environment of the heat insulation plate 100. At least a partial number of the first grooves 13 can extend along the width direction of the flexible housing 10, that is, the first grooves 13 are in a straight groove structure. At this time, multiple rows of the first grooves 13 can be arranged along the length direction of the flexible housing 10, and the first grooves 13 are arranged in parallel at intervals, so that the user can bend the heat insulation plate 100 at different first grooves 13 according to actual needs to adapt to the use environment of the heat insulation plate 100. It is also possible to arrange both the first grooves 13 extending along the length direction of the flexible housing 10 and the first grooves 13 extending along the width direction of the flexible housing 10, so that all the first grooves 13 form a grid structure, so that there are more bending points on the heat insulation plate 100 to adapt to the use requirements in more situations.

[0061] In some embodiments of the present invention, along the thickness direction of the flexible housing 10, at least one second groove 15 is locally recessed on the side of the flexible housing 10 facing away from the first grooves 13. A part of the second groove 15 is located between two adjacent installation cavities 11, and both ends of the second groove 15 are located at the edge of the flexible housing 10 along the extension direction of the second groove 15, and the heat insulation plate 100 can be bent at the second groove 15.

[0062] It can be understood that the first groove 13 can be provided on one side of the flexible housing 10, or the first groove 13 and the second groove 15 can be provided on both sides respectively. The first groove 13 is formed by pressing the first film 12 with a vacuum packaging machine 101, and the second groove 15 is formed by pressing the second film 14 with the vacuum packaging machine 101. That is, the second film 14 is pressed to form a plurality of second grooves 15 through the portions between the plurality of groove cells 31 on the upper partition plate 30 of the vacuum packaging machine 101. The core material 20 is filled into the installation cavity 11, and then the vacuum packaging machine 101 arranges the first film 12 and the second film 14 opposite to each other and heat-seals them to close the installation cavity 11 into a closed installation cavity 11. The plurality of installation cavities 11 are independent of each other, and the portions between adjacent two installation cavities 11 are recessed to form a second groove 15 section. When the number of installation cavities 11 is more than four, the number of second groove 15 sections is also more than two. The second groove 15 is formed by connecting the second groove 15 sections, and the portions between adjacent two second groove 15 sections are also recessed.

[0063] Specifically, the extending direction of the second groove 15 is determined by the distribution of the installation cavities 11 on the flexible housing 10. When the plurality of installation cavities 11 are arranged in sequence in one direction, the flexible housing 10 is in the shape of a long strip plate, and a part of the second groove 15 is formed between adjacent two installation cavities 11. The two ends of the second groove 15 respectively extend to two opposite edges of the flexible housing 10, so that the thickness at the second groove 15 is relatively thin, so that the heat insulation board 100 can be bent at the first groove 13, and the bending direction can be the direction in which the installation cavities 11 on both sides of the second groove 15 approach each other, or the direction in which the installation cavities 11 on both sides of the second groove 15 move away from each other. The installation cavities 11 can also be arranged in a rectangular array. At this time, the second groove 15 is formed between adjacent two columns of installation cavities 11, and the second groove 15 is formed between adjacent two rows of installation cavities 11. The second groove 15 located between adjacent two columns of installation cavities 11 intersects and communicates with the second groove 15 located between adjacent two rows of installation cavities 11. The second groove 15 is also provided with multiple rows and multiple columns and is arranged in a grid shape. When the user uses it, the heat insulation board 100 can be bent at any row or any column of the second groove 15 according to actual needs, so that the heat insulation board 100 is adapted to the actual use environment.

[0064] In some embodiments of the present invention, along the thickness direction of the flexible housing 10, the projection of the first groove 13 and the projection of the second groove 15 at least partially coincide.

[0065] It can be understood that in the length direction and width direction of the flexible housing 10, the positions of the first grooves 13 correspond to the positions of the second grooves 15. Specifically, the sizes and position distributions of the groove grids 31 on the upper partition 30 of the vacuum packaging machine 101 can be designed to be the same as those of the groove grids 31 on the lower partition 32. When the upper partition 30 is pressed against the lower partition 32, the positions and sizes of the groove grids 31 of the two correspond to each other. As a result, the positions and shapes of the first grooves 13 and the second grooves 15 formed after pressing are consistent. The thickness of the heat insulation board 100 at the grooves can be thinner, and the strength is sufficient, which is convenient for the user to bend at the first grooves 13, that is, the second grooves 15, during use. In addition, the width of the first grooves 13 can be different from the width of the second grooves 15 to adapt to more usage scenarios. At this time, the projections of the first grooves 13 and the second grooves 15 partially overlap.

[0066] In some embodiments of the present invention, the flexible housing 10 includes a first film layer 12 and a second film layer 14 disposed opposite to each other. The edge of the first film layer 12 is connected to the second film layer 14, and the portion of the first film layer 12 located between two adjacent core materials 20 is connected to the second film layer 14. A plurality of installation cavities 11 are defined between the first film layer 12 and the second film layer 14. Along the thickness direction of the flexible housing 10, at least one first groove 13 is formed by partial depression on the first side of the first film layer 12, and at least one second groove 15 is formed by partial depression on the second side of the first film layer 12.

[0067] It can be understood that the shapes of the first film layer 12 and the second film layer 14 are selected according to the shape required for the heat insulation board 100. For example, when the heat insulation board 100 is a rectangular plate, the first film layer 12 and the second film layer 14 are also rectangular. When the heat insulation board 100 is circular, the first film layer 12 and the second film layer 14 are also circular. During production, the upper partition 30 and the lower partition 32 of the vacuum packaging machine 101 can be designed into a waffle-like structure with a plurality of groove grids 31. The first film layer 12 is placed on the lower partition 32, and then the core material 20 is placed on the first film layer 12 with the position of the core material 20 corresponding to the groove grids 31. Then, the second film layer 14 is placed on the side of the core material 20 away from the first film layer 12. The upper partition 30 of the vacuum packaging machine 101 is controlled to be lowered to press the first film layer 12 and the second film layer 14 together, so that the edges of the first film layer 12 and the second film layer 14 are pressed and heat-sealed at the edges, and a section is left at the edge as an opening for vacuum pumping. Finally, the space between the first film layer 12 and the second film layer 14 is evacuated to make the first film layer 12 and the second film layer 14 fit together, and the installation cavities 11 are in a vacuum state and independent of each other. Finally, the remaining opening is heat-sealed to complete the production. In addition, the unfolded area of the first film layer 12 can be equal to the unfolded area of the second film layer 14, so that the first film layer 12 and the second film layer 14 can be processed simultaneously, saving cost and time.
