Description

Technical Field

[0001] The invention relates to the technical field of thermal insulation film blankets, in particular to a light-sensitive reflective aluminum thermal insulation film blanket. Background Art

[0002] Reflective aluminum thermal insulation blanket is a highly efficient thermal insulation material with a variety of excellent properties and application scenarios. Reflective aluminum thermal insulation blanket is suitable for various building envelope systems and heat and cold insulation scenarios, such as metal building envelope systems, thermal insulation, civil building envelope systems and other structures requiring heat and cold insulation.

[0003] A search revealed patent publication number CN219028767U, for example, which discloses a reflective bubble aluminum thermal insulation blanket for exterior wall insulation. The blanket comprises a main body composed of a forward aluminum foil scratch-resistant reinforcement layer, a supercritical reflective layer, a first nano-multi-layer anti-corrosion coating, a single nano-bubble layer, a tension mesh, a reverse high-reflectivity aluminum foil layer, and a second nano-multi-layer anti-corrosion coating. During use, this utility model continuously reflects radiant heat from the building surface by the aluminum thermal insulation blanket, limiting heat flow to the cooler areas on either side of the bubble layer between the aluminum thermal insulation blanket and the color-coated steel plate, effectively preventing heat from being conducted downward into the building. The forward and reverse aluminum foils, combined with scratch-resistant and anti-corrosion technology, reflect the vast majority of radiant heat, significantly reducing heat transfer. The nano-bubble layer, when pressed together, isolates the air from the building, reducing heat conduction. The adhesive-free composite tension mesh increases the tensile and tear resistance of the reflective aluminum thermal insulation blanket.

[0004] The above patents have obvious beneficial effects, but still have the following deficiencies in actual operation:

[0005] Traditional reflective aluminum thermal insulation blankets (such as the above-mentioned comparative documents) rely on the aluminum foil layer to reflect thermal radiation, but their reflectivity is fixed and cannot be dynamically adjusted according to light intensity. For example, when the temperature difference between day and night is large or the seasons change, the fixed reflectivity will lead to insufficient insulation during the day or excessive heat dissipation at night. The requirements for thermal insulation and heat preservation in different climate zones (such as high sunshine areas and cold areas) vary significantly, which reduces the applicability of thermal insulation blankets. Therefore, the field urgently needs to make improvements to light-sensitive reflective aluminum thermal insulation blankets to solve the defects of the existing technology. Summary of the Invention

DETAILED DESCRIPTION

[0043] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0044] See also Figures 1-12 A light-sensitive reflective aluminum thermal insulation blanket comprises a thermal insulation blanket body 1, which comprises, from the outside to the inside, a wear-resistant layer 2, a hydrophobic layer 3, a photosensitive response layer 4, a dynamic reflective layer 5, a thermal insulation layer 6, a reinforcement layer 7 and an adhesive layer 8; the photosensitive response layer 4 comprises a micro-photoelectric sensor and a main controller, which is connected to an interactive device via a signal transmission module; the dynamic reflective layer 5 is composed of an electrodeformable aluminum foil or a photothermal response aluminum foil, and the surface microstructure is adjusted by the main controller to change the reflectivity; and the blanket also comprises an energy storage unit for thermal energy storage, which is used to generate thermal energy for the thermal insulation blanket body 1 and realize the storage and directional release of thermal energy through the main controller.

[0045] Specifically, the wear-resistant layer 2 is a composite of silicon carbide nanoparticles (30 wt%) and a polyurethane matrix, and a coating with a thickness of 80 μm is formed by a spraying process. The surface is rolled with a diamond embossed texture (depth 0.2 mm). The hydrophobic layer 3 is deposited on the inner side of the wear-resistant layer 2 by CVD deposition of a PTFE film (thickness 15 μm), with a contact angle of 155°. The hydrophobic layer 3 realizes a self-cleaning function; the photosensitive response layer 4 is formed by magnetron sputtering vanadium dioxide nanoparticles (particle size 50 nm) on a transparent PET substrate. The phase transition temperature is 25℃, and the reflectivity increases from 50% to 80% when the light intensity is greater than 500Lux. The heat insulation layer 6 is an extruded polyethylene bubble layer (bubble diameter 1mm). The dynamic reflective layer 5 uses electrodeformable aluminum foil (thickness 0.1mm) or photothermal responsive aluminum foil. The electrodeformable aluminum foil is laser etched to form wrinkles with a depth of 100nm. When a voltage of 3V is applied, the wrinkles unfold and the reflectivity increases by 85%. When the main controller determines that the light is strong, it turns to the electrodeformable aluminum foil. The electrodes of the aluminum foil send current signals, and the deformation degree of the aluminum foil is adjusted by changing the current size. When the current increases, the aluminum foil deforms, the surface becomes rougher, and the reflection amount increases, thereby enhancing the reflection ability of solar radiation heat. When the light intensity weakens, the main controller reduces the current, the aluminum foil gradually returns to its original state, and the reflection amount decreases; or a photothermal response aluminum foil is used, and gallium indium tin alloy nanoparticles (particle size 30nm) are sputtered on the surface of the photothermal response aluminum foil. When the light intensity is greater than 800Lux, the particles expand, the surface roughness Ra increases from 0.1μm to 0.5μm, and the reflectivity increases from 60% to 80%. After the photothermal response aluminum foil absorbs solar radiation heat, the temperature of the photothermal response nanomaterial coating on the surface increases, and the microstructure changes, resulting in a change in the reflection amount. When the light is strong, the aluminum foil absorbs more heat and the reflection amount increases; when the light weakens, the temperature of the aluminum foil decreases, and the reflection amount decreases accordingly; the reinforcement layer 7 is a hot-pressed composite glass fiber mesh (warp and weft density 10×10 / cm 2 ) and galvanized steel strip (thickness 0.5mm), tensile strength 400N / 5cm; adhesive layer 8 is coated with light-curing acrylic glue (thickness 0.1mm), UV irradiation 20s to cure it, peel strength 6N / mm 2The main controller receives the signal from the micro-photoelectric sensor. When the light intensity is greater than 1000Lux, a voltage of 3V is applied to the electrodeformable aluminum foil, the surface wrinkles unfold, and the reflectivity is increased to 85%. The micro-photoelectric sensor and the main controller in the photosensitive response layer 4 realize intelligent perception and automatic adjustment of the ambient light. The main controller is connected to the interactive device through the 5G communication module. The user can view the working status, ambient light information, and temperature data of the thermal insulation film blanket in real time, and can remotely control the working mode of the thermal insulation film blanket as needed, thereby improving the applicability of the thermal insulation film blanket body 1. At the same time, through the energy storage unit that can generate heat energy for the thermal insulation film blanket body 1, the stored heat energy can be released through the main controller at night or in colder time periods to maintain the indoor temperature, thereby improving the use effect of the overall thermal insulation film blanket body 1 after installation and improving the overall user experience.

[0046] As a technical optimization solution of the present invention, the energy storage unit includes a refrigerant medium storage box 9 for storing refrigerant and a heat medium storage box 10 for storing heat medium and having a heat preservation effect. A plurality of elastic medium delivery pipes 11 are preset in the thermal insulation film blanket body 1. A connection port 12 is provided at the end position of the thermal insulation film blanket body 1. A quick plug connector 13 for connection is provided at the end of the medium delivery pipe 11. A first delivery pipe 14 is fixedly installed at both ends of the connected several medium delivery pipes 11. A shunt pipe 17 is provided between the ends of the several first delivery pipes 14. The refrigerant medium storage box 9 and the heat medium storage box 10 are provided with a plurality of elastic medium delivery pipes 11. A fifth delivery pipe 22 is provided on one side of the medium storage tank 10, and several sixth delivery pipes 32 are provided between the fifth delivery pipe 22 and the cold medium storage tank 9 or the hot medium storage tank 10. The sides of the fifth delivery pipe 22 and the sixth delivery pipe 32 are provided with solenoid valve bodies for controlling opening and closing. A delivery pump body 15 is provided between the diversion pipe 17 and the fifth delivery pipe 22, and a filter unit for filtering the fluid medium is provided between the delivery pump body 15 and the diversion pipe 17. Discharge pipes 37 are provided on the sides of the cold medium storage tank 9 and the hot medium storage tank 10, and a fluid infusion pipe 38 is also provided on one side of the cold medium storage tank 9.

[0047] Specifically, the refrigerant is water, and the refrigerant is stored in the refrigerant storage tank 9. When the light is strong, the refrigerant is transported to the shunt pipe 17 through the delivery pump body 15, and is transported to several first delivery pipes 14 through the shunt pipe 17. The first delivery pipe 14 is transported to several medium delivery pipes 11. When the medium delivery pipe 11 transports the refrigerant, the refrigerant replaces the heat on the insulation film blanket 1, causing the refrigerant temperature to rise, and the refrigerant is converted into a heat medium. It is then transported again through the first delivery pipe 14, the fifth delivery pipe 22, the sixth delivery pipe 32 at the other end, and the solenoid valve body intelligently controlled by the main controller to the heat medium storage tank 10 for heat preservation storage. During the refrigerant transportation process, a large amount of heat energy will be absorbed, thereby improving the thermal insulation effect of the insulation film blanket 1. At night or when the temperature is low, the delivery pump body 15 is turned on to remove the heat from the heat medium storage tank 10. The heat medium is transported in the reverse direction again, wherein the speed and flow rate of the medium transported in the medium transport pipe 11 can be controlled according to the power of the thermal insulation film blanket 1 that can absorb heat energy, thereby achieving the effect of increasing the temperature. By intelligently adjusting the thermal insulation and heat preservation performance, the energy consumption of the building or equipment in the process of air conditioning, cooling and heating is reduced. In summer, it effectively blocks solar radiation heat and reduces the frequency and load of indoor air conditioning. In winter, it uses the stored heat for insulation and reduces the operating time of the heating equipment, thereby achieving the purpose of energy saving and environmental protection, and meeting the requirements of sustainable development. Among them, when the refrigerant or heat medium is transported, it will be filtered through the filter unit to prevent the medium from containing a large amount of impurities, which will cause blockage of the medium transport pipe 11. The discharge pipe 37 is used to discharge the medium in the refrigerant medium storage box 9 or the heat medium storage box 10, and the refill pipe 38 is used to add new refrigerant.

[0048] As a technical optimization solution of the present invention, the filtering unit includes a second delivery pipe 18 fixedly installed on one side of the shunt pipe 17 and a third delivery pipe 19 connected to the delivery pump body 15 at one end. A fourth delivery pipe 20 is provided between the third delivery pipe 19 and the second delivery pipe 18. Several first filter pipes 16 communicating with the interior of the third delivery pipe 19 are provided on the side of the third delivery pipe 19. A second filter pipe 21 communicating with the fourth delivery pipe 20 is provided on the side of one end of the first filter pipe 16 away from the third delivery pipe 19. A filter device for filtering and being replaceable is provided in the second filter pipe 21. A liquid baffle 39 is fixedly installed in the shunt pipe 17. The liquid baffle 39 is adapted to the infusion direction of the second delivery pipe 18. The filtering device includes a first filter element 25, a second filter element 26 and a third filter element 27 installed in the first filter pipe 16. The first filter pipe 16 is provided with an installation step 24 adapted to the filtering device. A removable sealing head 23 is provided at one end of the first filter pipe 16 away from the third delivery pipe 19. A positioning boss 28 is provided on one side of the removable sealing head 23 that presses against the filtering device. The second filter pipe 21 and the first filter pipe 16 are provided with valves 29 for opening and closing at opposite ends. A sealing ring 30 is embedded between the side of the removable sealing head 23 and the end of the first filter pipe 16.

[0049] Specifically, the first filter element 25, the second filter element 26 and the third filter element 27 respectively include but are not limited to PP cotton, activated carbon and ultrafiltration membrane combination filter elements, and the installation order can be determined according to the actual situation. The PP cotton (polypropylene melt-blown filter element) is a three-dimensional network structure formed by polypropylene fiber through a melt-blown process. Its pore size range is 1-5 μm, which can intercept particles >5 μm. It has acid and alkali resistance and corrosion resistance, and no secondary pollution. The activated carbon filter element is granular activated carbon (GAC) or compressed activated carbon (CTO). Granular activated carbon is coconut shell or coal charcoal crushed into 0.2-0.5 mm particles. Compressed activated carbon (CTO) is formed by high-temperature compression of carbon powder and binder. It has higher density and stronger adsorption capacity. It passes through micropores (1-2 nm) and mesopores (2-50nm) to adsorb residual chlorine and organic matter (VOCs); the ultrafiltration membrane (hollow fiber ultrafiltration membrane) is composed of polysulfone (PSF), which has high temperature resistance (≤80℃), acid and alkali resistance and strong anti-pollution properties. Polyacrylonitrile (PAN) has good hydrophilicity and is suitable for high turbidity water sources. The pore size of the ultrafiltration membrane surface is 0.01-0.1μm, which can intercept bacteria (0.2-5μm) and viruses (0.02-0.3μm). Through the first filter element 25, the second filter element 26 and the third filter element 27, the trace elements contained in the refrigerant or the heat medium are reduced, and the scale generated in the medium conveying pipeline 11, the refrigerant medium storage box 9 or the heat medium storage box 10 is reduced, thereby extending the service life of the entire device. When the medium passes through the conveying pump body 1 During the conveying process, the medium flows from the first filter pipe 16 to the second filter pipe 21 or from the second filter pipe 21 to the first filter pipe 16, and both of them pass through the first filter element 25, the second filter element 26 and the third filter element 27. In addition, there are multiple first filter pipes 16 and second filter pipes 21, which can fully filter the flow medium and prevent the blockage of the first filter pipe 16 or the second filter pipe 21, which may cause the entire device to be unusable. When the flow medium flows from the second conveying pipe 18 to the diversion pipe 17, the flow medium hits the liquid baffle 39, and the flow medium falls to the bottom of the diversion pipe 17 and is evenly conveyed to multiple first conveying pipes 14, thereby increasing the amount of flow medium in each medium conveying pipe 11 and improving the flow of the medium. The temperature of the entire refrigerant is well controlled during heating. At the same time, due to the obstruction of the liquid baffle 39, the impact force (such as water hammer effect) caused by the conveying of the flowing medium on the medium conveying pipe 11 is reduced, thereby improving the service life of the entire device. When installing the first filter element 25, the second filter element 26 and the third filter element 27, the first filter element 25, the second filter element 26 and the third filter element 27 are clamped at the installation step 24 position in the first filter pipe 16, and the sealing ring 30 is embedded in one end of the first filter pipe 16. The detachable sealing head 23 is sealed and installed at one end of the first filter pipe 16 by bolts and the mounting flange. The positioning boss 28 on the detachable sealing head 23 is in close contact with the first filter element 25, the second filter element 26 and the third filter element 27.The first filter element 25, the second filter element 26 and the third filter element 27 are positioned and fixed to facilitate installation or later replacement of the first filter element 25, the second filter element 26 and the third filter element 27. When the first filter element 25, the second filter element 26 and the third filter element 27 in a first filter pipe 16 need to be replaced later, the two valves 29 on the first filter pipe 16 and the second filter pipe 21 are closed at the same time, and the first filter element 25, the second filter element 26 and the third filter element 27 in one first filter pipe 16 can be replaced. The first filter element 25, the second filter element 26 and the third filter element 27 in several first filter pipes 16 can be replaced in sequence. When replacing the first, second, and third filter elements 25, 26, and 27, there is no need to stop the flow of the cold or hot medium, making it easy to replace the first, second, and third filter elements 25, 26, and 27 without delaying the flow of the fluid. It is worth noting that if the first, second, and third filter elements 25, 26, and 27 are respectively composed of a combination filter element of PP cotton, activated carbon, and an ultrafiltration membrane, the flow medium temperature is ≤50°C, ensuring the filtration effect of the first, second, and third filter elements 25, 26, and 27. If the temperature in the installation area is too high, the high-temperature resistant filter material must be replaced.

[0050] As a technical optimization solution of the present invention, several layers of partition plates 31 are provided in the heat medium storage box 10, and several sixth conveying pipes 32 are adapted to the positions of the partition plates 31. A drive motor 33 is fixedly installed on the upper part of the heat medium storage box 10, and a rotating main shaft 34 that passes through the several partition plates 31 is fixedly installed on the output end of the drive motor 33. Several stirring rods 35 adapted to the partition plates 31 are fixedly installed on the side of the rotating main shaft 34. The stirring rods 35 are fixedly installed between the rotating main shaft 34 and the rotating frame 36, and the side of the rotating frame 36 is against the inner wall of the heat medium storage box 10 and the side of the partition plate 31.

[0051] Specifically, the heat medium storage box 10 and several partitions 31 are all made of thermal insulation material. The space between each two partitions 31 stores a flow medium of a certain period of time or at different temperatures. Through several sixth delivery pipes 32 and the electromagnetic valve bodies on the side thereof, the input and output of the flow medium in each space can be controlled to reduce the heat loss rate of the overall heat medium. When the heat medium is input, the drive motor 33 is turned on, and the output end of the drive motor 33 drives the rotating main shaft 34 to rotate. The rotating main shaft 34 drives the stirring rod 35 to rotate, stirring the heat medium in the heat medium storage box 10, ensuring the stability of the heat medium temperature in each cavity and improving the accuracy of subsequent control of the indoor temperature. The rotating frame 36 improves the connection strength of the stirring rod 35. The side of the rotating frame 36 is against the inner wall of the cavity storing the heat medium, scraping the inner wall of the cavity to facilitate the later cleaning of the heat medium storage box 10.

[0052] Among them, it is worth mentioning that the above-mentioned reflective aluminum insulation film blanket is mainly suitable for installation on the exterior walls of large buildings or on the outside of substrates that need to be insulated at night, such as large-scale installation in environments with large temperature differences between day and night. The number and size of its various transmission pipelines and the flow rate of refrigerants and heat media are determined according to actual sunshine conditions and insulation requirements. All of the above-mentioned electrical products can be purchased on the market. They are mature technologies and have been fully disclosed, so they are not repeated in the specification. All of the above-mentioned electrical products are equipped with power connection lines, and they are electrically connected to the external main controller and 220V phase voltage (or 380V line voltage) through the power lines, and the main controller can be a conventional known device such as a computer that plays a control role.
