Description

Technical Field

[0001] This utility model specifically relates to an integrated flexible insulation panel and its insulation box. Background Technology

[0002] In numerous fields such as cold chain transportation, building insulation, and home appliance manufacturing, the quality of insulation and heat insulation technologies plays a crucial role in energy efficiency, product performance, and cost control. Vacuum insulation panels, as a high-tech and environmentally friendly insulation material, have received considerable attention in recent years. Composed of a core filling material and a vacuum-protected surface layer, they effectively prevent heat transfer caused by air convection, significantly reducing thermal conductivity. They do not generate environmental pollution during manufacturing, use, or post-use disposal, and are therefore widely used in systems such as refrigeration, freezing, and heat preservation.

[0003] Because insulation panels are not rigid in practical applications, their dimensional accuracy is not high. Currently, insulation panels on the market are usually designed as three-dimensional structures, requiring vacuuming before transportation. This process is cumbersome, and the production efficiency of three-dimensional insulation panels is low, affecting the efficiency of the insulation box. Furthermore, the barrier membrane of vacuum insulation panels is easily punctured or worn. Once the barrier membrane is damaged, outside air and moisture will quickly enter the core material, severely disrupting the internal vacuum environment of the vacuum insulation panel and causing a sharp decline in its insulation performance. During daily use, handling, and transportation of the insulation box, vacuum insulation panels inevitably suffer from external forces such as collisions and friction, which pose a significant threat to the integrity of their barrier membrane.

[0004] Therefore, it is necessary to invent an integrated flexible insulation panel and its insulation box to solve the above problems. Utility Model Content

[0005] (a) Purpose of the utility model

[0006] To address the technical problems existing in the background art, this utility model proposes an integrated flexible insulation board and its insulation box.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] An integrated flexible insulation panel includes a top cover insulation panel and a box body insulation panel, which together form a box structure.

[0010] The insulation panel of the enclosure includes a barrier film and a core panel. The barrier film is rectangular in shape. Multiple core panels are provided and placed inside the barrier film and wrapped around it. The core panels are assembled with the barrier film.

[0011] Preferably, the barrier film has multiple adjacent mounting areas inside, wherein the core board is installed in the mounting area, and each core board is installed independently.

[0012] Preferably, multiple core plates are placed inside the barrier film and are foldable as a whole, and the core plates and other mounting positions in the mounting area are all set to vacuum.

[0013] Preferably, the barrier film and the core board are folded into a box structure, and adjacent installation areas are fixed by an external adhesive structure.

[0014] An insulated box includes the aforementioned integrated flexible insulation panel, and also includes a top cover assembly and a box body assembly, wherein the top cover assembly is installed on the top of the box body assembly;

[0015] The top cover assembly includes a top cover and a fixing plate. The bottom of the top cover is provided with a mounting groove. The fixing plate is installed at the opening of the mounting groove, and the top cover insulation plate is fixed in the mounting groove.

[0016] The enclosure assembly includes an outer enclosure and an inner enclosure. The inner enclosure is installed inside the outer enclosure, and a fixing groove is provided between the two. The enclosure insulation board is installed in the fixing groove.

[0017] Preferably, the fixing plate has multiple fixing protrusions on both sides, and the inner wall of the mounting groove has fixing grooves on both sides that match the fixing protrusions.

[0018] Preferably, the outer casing has a positioning slot at the top opening, and the inner casing has a limiting plate extending outward from the top, which is fitted into the positioning slot.

[0019] Preferably, the top cover is installed on the top of the outer casing and the inner casing, and the mounting groove at its bottom is matched and positioned at the opening of the inner casing.

[0020] Compared with the prior art, the beneficial effects of the above-mentioned technical solution of this utility model are:

[0021] 1. This utility model uses the mounting groove at the bottom of the top cover to match the opening of the inner box. The outer box and the inner box are sealed and connected by the limiting plate. With the vacuum structure of the insulation board, the heat exchange channel is blocked from key positions such as the box joint and the top opening, so as to avoid the loss of cold or hot air due to poor sealing.

[0022] 2. The core plate of this utility model is independently installed and distributed in a cross shape, which not only ensures the support strength of the flexible material, but also forms an overall stress structure through the wrapping of the barrier film; the inner box design inside the outer box forms a composite structure of double box and middle insulation layer, which enhances the impact resistance and deformation resistance of the box and extends its service life.

[0023] 3. The modular design of this utility model reduces the complexity of production and assembly. Compared with traditional rigid insulation materials, flexible materials and vacuum structures have advantages in material cost and transportation cost, and are highly reusable, making them more economical for long-term use.

[0032] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0033] This utility model provides, for example Figure 1-5 The integrated flexible insulation panel shown includes a top cover insulation panel 1 and a box body insulation panel 2, which together form a box structure.

[0034] Reference Figure 3The insulation panel 2 of the box includes a barrier film 21 and a core panel 22. The barrier film 21 is rectangular in shape. Multiple core panels 22 are provided and placed inside the barrier film 21 to wrap it. The core panels 22 are assembled with the barrier film 21.

[0035] In this embodiment, a flexible barrier membrane 21 with high barrier properties is selected, and the core plate 22 is made of a lightweight insulation material with low thermal conductivity. The top cover insulation plate 1 has a similar structure to the box insulation plate 2, and its size is adapted to the top cover assembly 3 and the box assembly 4.

[0036] Specifically, the barrier membrane 21 has nine adjacent installation areas inside, of which five installation areas are equipped with core plates 22, and each core plate 22 is installed independently.

[0037] Specifically, multiple core plates 22 are placed in the middle of the barrier film 21 and arranged in a cross shape within the installation area. The core plates 22 and other installation positions in the installation area are all set to vacuum.

[0038] Specifically, the barrier film 21 and the core plate 22 are folded into a box structure, and adjacent installation areas are fixed by an external adhesive structure.

[0039] In this embodiment, the rectangular barrier film 21 is divided into 9 adjacent installation areas, arranged in a 3×3 matrix. Five of these installation areas are positioned in a cross shape: one in the center, and one each on the top, bottom, left, and right. However, in actual production and assembly, the installation of the core board 22 is not limited to the cross-shaped arrangement in this embodiment, and the total number of core boards 22 is not limited to the adjacent areas. Figure 4 As shown;

[0040] Specifically, the core plate 22 is installed independently in the cross-shaped installation area to ensure that the core plate 22 is in close contact with the inner wall of the barrier film 21;

[0041] Specifically, all installation areas are evacuated before being installed into the insulation box to create a vacuum environment inside and reduce heat conduction.

[0042] Specifically, the barrier film 21 and the core plate 22 are folded together along the boundary of the installation area to form a box structure. Adjacent installation areas are fixed by an external adhesive structure to ensure the stability of the shape after folding.

[0043] In this embodiment, the flexible material of the barrier film 21 allows for overall folding, which facilitates transportation and storage. After folding, it is fixed by an adhesive structure, taking into account both flexibility and structural stability.

[0044] Reference Figure 1-2 An insulated box includes a top cover assembly 3 and a box body assembly 4, wherein the top cover assembly 3 is installed on the top of the box body assembly 4;

[0045] Specifically, the top cover assembly 3 includes a top cover 31 and a fixing plate 32. The bottom of the top cover 31 is provided with an installation groove 33. The fixing plate 32 is installed at the opening of the installation groove 33, and the top cover insulation plate 1 is fixed in the installation groove 33.

[0046] Specifically, the enclosure assembly 4 includes an outer enclosure 41 and an inner enclosure 42. The inner enclosure 42 is installed inside the outer enclosure 41, and a fixing groove 43 is provided between the two. The enclosure insulation board 2 is installed in the fixing groove 43.

[0047] In this embodiment, the top cover insulation plate 1 is placed in the mounting groove 33 at the bottom of the top cover 31; the fixing plate 32 is aligned with the groove opening of the mounting groove 33, so that the fixing protrusions 34 on both sides of the fixing plate are engaged in the fixing grooves 35 on the inner wall of the mounting groove, thus completing the assembly of the top cover assembly. The fixing plate 32 is used to press the top cover insulation plate 1 to prevent displacement.

[0048] Specifically, the fixing plate 32 has multiple fixing protrusions 34 on both sides, and the inner wall of the mounting groove 33 has fixing grooves 35 that match the fixing protrusions 34 on both sides.

[0049] Specifically, the top opening of the outer casing 41 is provided with a positioning slot 44, and the top of the inner casing 42 extends outward with a limiting plate 45, which is matched and installed in the positioning slot 44.

[0050] Specifically, the top cover 31 is installed on the top of the outer casing 41 and the inner casing 42, and its bottom mounting groove 33 is matched and positioned at the opening of the inner casing 42.

[0051] In this embodiment, the inner box 42 is placed inside the outer box 41, so that the limiting plate 45 at the top of the inner box is embedded in the positioning slot 44 at the top opening of the outer box, ensuring that the inner and outer boxes are relatively fixed and forming a middle fixing slot 43.

[0052] Specifically, the prefabricated box insulation board 2 is placed into the fixing groove 43 to ensure that the insulation board fits against the inner and outer walls of the box, thereby improving the insulation effect.

[0053] Specifically, the top cover assembly 3 is placed on top of the outer box 41 and the inner box 42, so that the edge of the mounting groove 33 at the bottom of the top cover is matched and positioned at the opening of the inner box 42, thus completing the overall assembly of the insulation box.

[0054] In this embodiment, the matching and positioning of the mounting groove 33 with the opening of the inner box ensures that the top cover 31 is tightly closed, reducing the entry of external hot or cold air, so that the insulated box can keep the inside hot or cold, and its practicality is strong.

[0055] It is worth mentioning that the installation of the barrier film 21 and the core plate 22 in this embodiment conforms to the internal tank structure of the insulation box and is not limited to one installation method in this embodiment. Furthermore, the number of core plates 22 is not limited to the number in this embodiment, as long as it can match the internal insulation installation requirements of the insulation box.

[0056] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
