[0034] With the development of technology, refrigeration equipment is becoming increasingly diversified. However, the doors of traditional refrigeration equipment usually use non-transparent vacuum insulation panels, which prevent users from directly observing the items stored inside. Sometimes users have to open and close the door frequently to check the status of the ingredients, which not only increases energy consumption but may also affect the preservation of food.

[0035] Based on this, the present application proposes a method for manufacturing a transparent vacuum insulation panel. The prepared vacuum insulation panel has a transparent visible area in the middle, which solves the defect that the existing refrigeration equipment door body cannot intuitively observe the food situation inside, allowing users to observe the internal items without opening the door while maintaining excellent thermal insulation performance.

[0036] It should be noted that the transparent vacuum insulation panels of this application can be used in a variety of insulation scenarios that require observation. The refrigeration equipment mentioned in this application can be a refrigerator, a freezer, a refrigerated display cabinet, or a refrigerated medicine cabinet. Specifically, the transparent vacuum insulation panels can be used on the door of the refrigeration equipment. For example, the transparent vacuum insulation panels of this application can be used on the door of the refrigeration equipment. Of course, in addition to being used on the door of the refrigeration equipment, they can also be used on the side walls of the cabinet of the refrigeration equipment. No specific restrictions are set here.

[0037] The following combination Figures 1 to 7 The transparent vacuum insulation panel and the manufacturing method thereof of the present application are described.

[0038] According to the transparent vacuum insulation panel of the embodiment of the present application, please refer to Figures 1 to 4 The transparent vacuum insulation panel includes a pair of oppositely arranged transparent substrates 1, a supporting unit 2, an adhesive film 3 and a barrier film 4, wherein the supporting unit 2 is arranged between the transparent substrates 1 and is used to connect the transparent substrates 1; the adhesive film 3 is arranged on the side of the transparent substrate 1 away from the supporting unit 2, and the adhesive film 3 is arranged at the edge of the transparent substrate 1; the barrier film 4 is connected to the adhesive film 3, and the barrier film 4 and the transparent substrate 1 enclose a vacuum cavity 5.

[0039] According to the embodiment of the present application, the transparent vacuum insulation panel not only has a transparent visible area for users to observe, but also has excellent thermal resistance performance.

[0040] It can be understood that the transparent substrate 1 provides a transparent observation area for the user, allowing the insulation panel to provide both insulation and internal observation. The support unit 2 is used to connect the transparent substrates 1, ensuring the relative position between the substrates is stable and preventing deformation of the transparent substrates 1 due to atmospheric pressure during the vacuuming process.

[0041] Adhesive film 3 is disposed on the edge of transparent substrate 1, facing away from support unit 2. Barrier film 4 is connected to adhesive film 3 and forms a vacuum chamber 5 with transparent substrate 1. The presence of vacuum chamber 5 significantly reduces the paths for heat conduction and convection, effectively reducing heat transfer. This gives the insulation board excellent thermal resistance, effectively preventing heat transfer and providing excellent insulation.

[0042] According to one embodiment of the present application, the barrier bag is an aluminized composite film barrier bag or an aluminum foil composite film barrier bag.

[0043] The barrier bag is formed by removing parts to form a barrier film.

[0044] According to an embodiment of the present application, the transparent substrate 1 is one of a glass substrate, an acrylic substrate, and a polycarbonate substrate.

[0045] According to one embodiment of the present application, the support unit 2 is a transparent support unit.

[0046] In one embodiment, the support unit 2 is one of a glass support unit, an acrylic support unit, and a polycarbonate support unit.

[0047] In one embodiment, the supporting unit 2 and the transparent substrate 1 are made of the same material.

[0048] According to one embodiment of the present application, the diameter of the support unit is 0.1 mm-1 mm.

[0049] According to one embodiment of the present application, the spacing between the support units is 10 mm-50 mm.

[0050] According to the manufacturing method of a transparent vacuum insulation panel proposed in the embodiment of the present application, please refer to Figures 1 to 7 , including: step 100, step 200, step 300, step 400, step 500 and step 600.

[0051] Step 100 : Dispose a ring-shaped adhesive film 3 on the edge of one side of the transparent substrate 1 .

[0052] Step 200 : Arrange a pair of transparent substrates 1 provided with adhesive films 3 opposite to each other, and arrange a support unit 2 between the transparent substrates 1 , wherein the adhesive films 3 are arranged on the outer sides of the transparent substrates 1 .

[0053] Step 300: Place the transparent substrate 1, the adhesive film 3 and the supporting unit 2 into a barrier bag as a whole to form a pre-packaged assembly.

[0054] Step 400: vacuum-pack the pre-packaged component to form a vacuum-packed component.

[0055] Step 500 : hot pressing the position where the adhesive film 3 is provided on the vacuum packaging component.

[0056] Step 600 : removing the barrier film 4 in the inner area of the adhesive film 3 to form a central transparent visible area on the end surface of the transparent substrate 1 , wherein the barrier film 4 is a part of the barrier bag structure.

[0057] According to the method for manufacturing a transparent vacuum insulation panel according to an embodiment of the present application, the prepared transparent vacuum insulation panel not only has a transparent visible area for users to observe, but also has excellent thermal resistance performance.

[0058] In step 100, a transparent substrate 1 is made of a high-transmittance material (such as glass, polycarbonate, or acrylic) that ensures smooth light transmission, allowing a user to clearly see items placed behind it. An adhesive film 3 is applied to the edges of the transparent substrate 1. The adhesive film 3 can be coated on the surface of the transparent substrate 1 and then adhered to the transparent substrate 1 through physical conditions (such as high temperature) or chemical conditions. In some possible embodiments, the adhesive film 3 can be applied to the transparent substrate 1 through a vacuum hot-melt rolling process, where the heating temperature can be 80°C to 120°C and the pressure can be 0.2 MPa to 0.5 MPa. In some possible embodiments, the adhesive film 3 is applied to the edges of the transparent substrate 1 using hot-melt adhesive or UV-curable adhesive, either by coating or pre-forming.

[0059] It is understood that the annular width of the adhesive film 3 is adjustable according to the size of the substrate. In some possible embodiments, for a transparent substrate 1 of 500 mm × 500 mm, the width of the adhesive film 3 is 8 mm. In some possible embodiments, for a transparent substrate 1 of 1000 mm × 1000 mm, the width of the adhesive film 3 is 12 mm.

[0060] In some possible embodiments, the adhesive film is a hot-melt ethylene-vinyl acetate copolymer (EVA) adhesive film, and the thickness of the adhesive film is in the range of 0.2 mm to 0.5 mm.

[0061] In step 200, two transparent substrates 1, each coated with adhesive film 3, are placed opposite each other. A support unit 2 is provided between the two transparent substrates 1 to support and connect them. The support unit 2 supports the two transparent substrates 1 and maintains the spacing between them. This prevents deformation of the transparent substrates 1 due to atmospheric pressure during the vacuuming process, which could affect the normal use of the transparent viewing area. Furthermore, the support unit 2 itself is transparent and does not obstruct the viewing area.

[0062] In some embodiments, the support units 2 are evenly arranged between the two transparent substrates 1 . Specifically, the support units 2 are evenly distributed in an array. In some possible embodiments, the spacing between the support units 2 is 20-50 mm.

[0063] In step 300, the assembled transparent substrate 1, adhesive film 3, and support unit 2 are placed in a barrier bag, ensuring that the bag completely encloses the internal structure. The barrier bag provides initial protection and isolation, laying the foundation for subsequent vacuum packaging.

[0064] In some possible embodiments, the barrier bag is a three-side sealed barrier bag with a thickness of 0.1-0.3 mm. During assembly, ensure that the barrier bag completely covers the internal structure, leaving one side open for vacuuming.

[0065] In step 400, a vacuum pump is used to evacuate the pre-packaged assembly, extracting the air from the interior. Once the desired vacuum level is achieved, the assembly is packaged and the barrier bag opening is heat-sealed. This vacuum operation removes the air from the pre-packaged assembly, creating a vacuum environment. A vacuum environment has extremely low thermal conductivity, significantly reducing heat transfer and thus improving the insulation performance of the insulation panel.

[0066] In step 500, the vacuum packaging assembly is placed in a hot press, where the area where the adhesive film 3 is located is heated and pressurized. The heating temperature and pressure are adjusted based on the material and properties of the adhesive film 3 to ensure that the adhesive film 3 is fully melted and fills the gap, ensuring that the barrier film 4 of the barrier bag is tightly attached to the transparent substrate 1.

[0067] In some possible embodiments, a hot pressing treatment at a temperature of 100° C. to 150° C. and a pressure of 0.3 to 0.8 MPa is applied to the adhesive film 3 for 30 to 60 seconds to melt the adhesive film 3 and fill the gap between the barrier film 4 and the transparent substrate 1 to ensure sealing.

[0068] In step 600, the barrier film 4 is removed from the inner area of the adhesive film 3, forming a central transparent visible area on the end surface of the transparent substrate 1. After removing the excess barrier film 4, the visible area between the transparent substrates 1 is exposed, allowing the user to clearly observe the interior of the insulation board.

[0069] It should be noted that, since the transparent vacuum insulation panel of the present application is prepared by the above-mentioned method for manufacturing the transparent vacuum insulation panel, the transparent vacuum insulation panel of the present application has all the technical effects of the above-mentioned method for manufacturing the transparent vacuum insulation panel, which will not be repeated here.

[0070] According to an embodiment of the present application, disposing a ring-shaped adhesive film 3 on an edge of one side of the transparent substrate 1 includes: step 110 and step 120 .

[0071] Step 110 : Coating the adhesive film 3 on the edge of the transparent substrate 1 .

[0072] Step 120 , placing the adhesive film and the transparent substrate 1 into a vacuum laminator, heating the adhesive film 3 and the transparent substrate 1 , vacuuming them, and rolling and pressing them to fix them.

[0073] In step 110 , the prefabricated adhesive film 3 material is precisely coated on the edge area of the transparent substrate 1 . The coating method can be automated dispensing equipment or screen printing technology to ensure that the adhesive film 3 evenly covers the target area.

[0074] In some possible embodiments, the automated dispensing equipment may be a high-precision dispensing machine equipped with a CCD visual positioning system to ensure the accuracy of the covering position of the adhesive film 3 .

[0075] In some possible embodiments, the screen printing technology may use a screen printing device with a screen mesh of 100-200 meshes.

[0076] In step 120, the adhesive film and the transparent substrate 1 are placed in a vacuum laminator, and heated vacuum rolling is performed to achieve a high-strength bond between the adhesive film 3 and the substrate through the synergistic effect of thermal energy, vacuum environment, and mechanical pressure. Thermal energy activates the fluidity of the colloid, causing the adhesive film 3 to change from a solid state to a flowable liquid or semi-solid state. The vacuum environment can expel the air between the adhesive film 3 and the transparent substrate 1. Rolling can increase the contact area between the adhesive film 3 and the substrate, promote the mutual diffusion of molecular chains, and form chemical bonds or mechanical interlocking.

[0077] According to one embodiment of the present application, the adhesive film 3 is a hot melt adhesive film 3, and the adhesive film 3 includes at least one of polyethylene (PE), polypropylene (PP), ethylene-vinyl acetate copolymer (EVA), polyolefin elastomer (POE) or ethylene-acrylic acid copolymer (EAA).

[0078] It should be noted that the thickness of the adhesive film 3 needs to be adapted to the width of the adhesive film 3 to prevent the adhesive film 3 from overflowing during hot pressing while ensuring the bonding strength.

[0079] According to one embodiment of the present application, hot pressing the position where the adhesive film 3 is provided on the vacuum packaging component includes step 510 and step 520 .

[0080] Step 510: Place the vacuum packaging assembly into a hot press, wherein the hot pressing plate of the hot press and the adhesive film 3 have the same size.

[0081] Step 520: hot pressing at a preset hot pressing temperature for a preset hot pressing time.

[0082] In step 510, the vacuum packaging assembly is placed in a hot press. The hot pressing plate of the hot press is consistent in size with the adhesive film 3 to ensure that the adhesive film 3 is not misaligned with the substrate. Specifically, positioning pins or clamps can be used to fix the assembly to avoid displacement during the hot pressing process.

[0083] In some possible embodiments, hot pressing is performed at a preset hot pressing temperature for a preset hot pressing time, and the pressure during this process can be kept constant.

[0084] In one embodiment, the preset hot pressing temperature is 140° C. to 200° C., and the preset hot pressing time is 5 seconds to 60 seconds.

[0085] The door body according to the third embodiment of the present application includes the above-mentioned transparent vacuum insulation panel.

[0086] As you can see, the transparent vacuum insulation panel, with its transparent substrate 1, provides a transparent observation area, allowing users to clearly observe the interior through the door. Furthermore, the internal vacuum chamber 5 structure, along with the synergistic effects of the support unit 2, adhesive film 3, and barrier film 4, imparts excellent thermal resistance to the door, effectively preventing heat transfer and achieving excellent insulation.

[0087] It should be noted that, since the door body of the present application is prepared by the above-mentioned method for manufacturing the transparent vacuum insulation panel, the door body of the present application has all the technical effects of the above-mentioned method for manufacturing the transparent vacuum insulation panel, which will not be repeated here.

[0088] According to the fourth embodiment of the present application, the refrigeration device includes a box body and the above-mentioned door body, the box body is provided with a cavity and an opening, the opening is connected to the cavity, and the door body cover is provided on the opening.

[0089] The refrigeration unit consists of a cabinet and the aforementioned door, a combination that complements and enhances their functions. The cabinet, the primary load-bearing structure, contains a cavity for refrigerated items, such as food. The door, installed over the cabinet opening, seals the cavity, preventing cold air from leaking and heat from entering.

[0090] The transparent vacuum insulation panels integrated into the door allow users to visually observe the contents of the cabinet without opening the door, such as checking the freshness of food, making management and operation easier. Furthermore, the excellent thermal resistance of the transparent vacuum insulation panels effectively prevents heat transfer between the cabinet and the outside, reducing cold air loss, improving the cooling efficiency of the refrigeration equipment, and reducing energy consumption.

[0091] Finally, it should be noted that the above embodiments are intended only to illustrate the present application and are not intended to limit the present application. Although the present application has been described in detail with reference to the embodiments, those skilled in the art will appreciate that various combinations, modifications, or equivalent substitutions of the technical solutions of the present application do not depart from the spirit and scope of the technical solutions of the present application and are intended to be encompassed by the claims of the present application.
