[0003] Although existing vacuum-insulated cavity type energy-saving insulation panels can use vacuum for insulation, when they are used in different environments after leaving the factory, the vacuum level inside the vacuum cavity is easily affected by the external atmospheric pressure, which may lead to deformation of the sidewalls of the vacuum cavity and affect normal use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a vacuum-insulated cavity type energy-saving heat insulation panel, comprising a panel frame, splicing components, and a vacuum adjustment component. The splicing components are provided on both sides of the outer side of the panel frame. Two fixed base plates are fixed inside the panel frame, and a vacuum cavity is provided between the fixed base plates. A pressure sensor is installed on the upper side inside the vacuum cavity. A vacuum adjustment component is installed on the lower side inside the vacuum cavity. The vacuum adjustment component includes an air bladder layer, a fixed connecting pipe, and a micro air pump.

[0017] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0018] like Figure 1 , Figure 2 and Figure 5 As shown, a vacuum-insulated cavity type energy-saving heat insulation panel includes a frame 1, splicing components 2, and a vacuum adjustment component 9. The splicing components 2 are provided on both outer sides of the frame 1. Each splicing component 2 includes a mating groove 201 and a first positioning hole 202. The upper and lower right sides of the frame 1 are provided with mating grooves 201, and the frame 1 at the mating grooves 201 has a first positioning hole 202. The splicing component 2 also includes a slot 203 and a sealing strip 204. The slot 203 is located in the middle of the right side of the frame 1, and the inner wall of the slot 203 is embedded with a sealing strip 204. The splicing component 2 also includes a mating plate 205 and a second positioning hole 206. The upper and lower left sides of the frame 1 are fixed with mating plates 205, and the dimensions of the mating plates 205 match the mating grooves 201. The connecting plate 205 has a second positioning hole 206 in the middle. The splicing component 2 also includes a retaining strip 207. The retaining strip 207 is integrally fixed in the middle of the left side of the plate frame 1, and the retaining strip 207 is engaged with the retaining groove 203. The two plate frames 1 can be spliced ​​in pairs. The left connecting plate 205 of one plate frame 1 can be inserted into the right connecting groove 201 of the other plate frame 1. At the same time, the left retaining strip 207 of one plate frame 1 can be inserted into the right retaining groove 203 of the other plate frame 1. Then, the corresponding length of the positioning pin is embedded in the second positioning hole 206 and the first positioning hole 202 to realize the splicing assembly. At the same time, due to the limiting effect of the connecting plate 205 and the retaining strip 207, the two plate frames 1 are not easy to move up and down or left and right, and the connection is relatively stable.

[0019] like Figures 2-3As shown, two fixed substrates 3 are fixed inside the frame 1, and a vacuum cavity 4 is provided between the fixed substrates 3. A pressure sensor 8 is installed on the upper side of the vacuum cavity 4. A composite phase change material layer 5 is provided on the outer surface of the outer fixed substrate 3, and an outer protective plate 6 is installed on the outer side of the composite phase change material layer 5. The outer protective plate 6 has embedded reinforcing ribs 7, and the reinforcing ribs 7 have a "well" shaped structure. The two fixed substrates 3 are fixedly connected to the frame 1, and graphene-modified silicone rubber is provided at the connection gap between the fixed substrates 3 and the frame 1. When microcracks occur, the graphene sheets automatically migrate to fill the gaps. At the same time, the viscoelastic damping of the silicone rubber dissipates high-frequency vibration energy. The vacuum cavity 4 between the two fixed substrates 3 can play a role in heat insulation. Meanwhile, the outer composite phase change material layer 5 is an expanded graphite composite phase change layer, which can achieve efficient heat energy storage and release through the thermophysical properties of the material, thereby further reducing temperature fluctuations. The outermost outer protective plate 6 has high hardness and can play a certain protective role.

[0020] like Figures 3-4 As shown, a vacuum regulating component 9 is installed on the lower side of the interior of the vacuum chamber 4. The vacuum regulating component 9 includes an airbag layer 901, a fixed connecting pipe 902, and a micro air pump 903. The lower side of the airbag layer 901 is bonded and fixed to the lower wall of the vacuum chamber 4. The valve side of the airbag layer 901 is connected to the fixed connecting pipe 902, and the micro air pump 903 is installed on one side of the fixed connecting pipe 902. The micro air pump 903 is embedded in the lower side of the outer protective plate 6, and the micro air pump 903 is interconnected with the airbag layer 901 through the fixed connecting pipe 902. The pressure sensor 8, as an important component of the vacuum system, can detect the internal pressure of the vacuum chamber 4. When the internal pressure of the vacuum chamber 4 changes due to external atmospheric pressure or other external factors, it can adjust the expansion degree of the air bladder layer 901 to reduce the impact of changes in vacuum degree. For example, when the change in vacuum degree of the vacuum chamber 4 causes the fixed substrate 3 to be dented and deformed, the micro air pump 903 can inflate the air bladder layer 901 through the fixed connecting pipe 902, thereby adjusting the internal pressure of the vacuum chamber 4 and restoring the chamber structure.

[0021] In summary, as Figures 1-5As shown, when using this vacuum-insulated cavity type energy-saving heat insulation panel, the two panel frames 1 can be spliced ​​together in pairs. During splicing, the left side mating plate 205 of one panel frame 1 can be inserted into the right side mating groove 201 of the other panel frame 1, and the left side locking strip 207 of one panel frame 1 can be inserted into the right side locking groove 203 of the other panel frame 1. Then, the corresponding length of the positioning pin is embedded in the second positioning hole 206 and the first positioning hole 202 to realize the splicing assembly. The two fixed base plates 3 are fixedly connected to the panel frames 1, and graphene modified silicone rubber is provided at the connection gap between the fixed base plates 3 and the panel frames 1. When micro-cracks occur, the graphene sheets automatically migrate to fill the gaps, and the viscoelastic damping of the silicone rubber dissipates the high-frequency vibration energy. During use, the vacuum cavity 4 between the two fixed substrates 3 can serve as a heat insulation layer. Meanwhile, the outer composite phase change material layer 5 is an expanded graphite composite phase change layer, which can achieve efficient heat storage and release through the thermophysical properties of the material, thereby further reducing temperature fluctuations. The outermost outer protective plate 6 has high hardness and can provide a certain degree of protection. The pressure sensor 8 can detect the internal pressure of the vacuum cavity 4. When the internal pressure of the vacuum cavity 4 changes due to external atmospheric pressure or other external factors, it can adjust the expansion degree of the airbag layer 901 to reduce the impact of vacuum degree changes. For example, when the vacuum degree of the vacuum cavity 4 changes and causes the fixed substrate 3 to be concave and deformed, the micro air pump 903 can inflate the airbag layer 901 through the fixed connecting pipe 902, thereby adjusting the internal pressure of the vacuum cavity 4 and restoring the cavity structure. This completes the use process of the vacuum insulation cavity type energy-saving heat insulation board.
