Description

Transparent thermal insulation board

Technical field

The invention relates to a light-transmitting and heat-insulating technology for building solar energy using heat-insulating and heat-transmitting partitions. Background technique

Buildings and other transparent partitions that require light transmission and thermal insulation often require consideration of both light transmission and thermal insulation in practical applications: such as building windows and glass greenhouse partitions.

Doors and windows are an indispensable part of the building. 60% to 80% of the energy consumption of the doors and windows is caused by heat conduction through the glass parts. Therefore, the energy saving of doors and windows mainly refers to the energy saving of glass. The forms of heat gain and heat loss of residential doors and windows include: solar heat gain, heat conduction, and air penetration. The world's door and window energy-saving technologies are experiencing a change from passive energy saving to active energy saving: that is, the direction from avoiding the incidence of sunlight to actively using solar energy. Developed countries take the lead in adopting window energy rating evaluation systems to evaluate various window energy ratings in heating and cooling seasons, such as the ER system in Canada and the NFRC system in the United States. In this rating system, the solar heat gain coefficient shows Large importance, while the weight of the window heat transfer coefficient is relatively small, and the influence of the permeability coefficient is relatively small to be almost negligible. Therefore, considering the solar heat transfer coefficient, window heat transfer coefficient, and air leakage coefficient, the cost and The simultaneous decrease in heating energy consumption is the key to energy saving in doors and windows.

Ideal energy-saving doors and windows should have good light transmission and excellent heat insulation properties. The effective methods of improving the solar heat gain coefficient of doors and windows for heating and energy saving are: increasing the window frame area ratio, light transmittance, and controlling the number of glass layers. There are many effective ways to improve the thermal insulation of doors and windows. According to test data, 50% to 70% of the energy consumption of external doors and windows is caused by conduction heat transfer in glass parts. In hollow and double-layer double-glass windows and doors, heat conduction The methods are divided into radiation, heat conduction and convection. Radiation heat transfer (including visible light and infrared light) accounts for about 60%. Its coefficient value depends on the temperature difference between the inner surfaces of the two sheets of glass and the emissivity of the interlayer gas. The current technology mainly uses the coating method Reduce radiant heat transfer. For example, double-layer insulating glass with coated glass is filled with dry air or inert gas to protect the coating layer. At the same time, a layer spacing of 6-9 mm is set to enhance heat insulation. However, due to actual production and processing, It is difficult to avoid gas leakage during use, so the coating layer is not protected, and the actual reliability is not high. The service life of coated insulating glass is generally less than 10 years. In addition, the transmittance of coated glass is generally 70 % Or less has a great impact on the heating energy saving performance of improving the solar heat gain coefficient.

-1-Confirm this The second is that heat conduction and heat transfer account for about ₃₇ %, which is mainly completed by glass and the air inside it. Because air is a poor conductor of heat, increasing the thickness of the gas spacer layer has a significant effect on reducing heat conduction and heat transfer. Its value depends on the glass gas. The thickness of the spacer layer, too large the thickness of the gas spacer layer will lead to a large increase in convective heat transfer. Generally, the suitable thickness of the gas spacer layer is 6-9 mm. In addition, the presence of active molecules such as water molecules in the air also affects The important factors of conductive and convective heat transfer have produced a method such as using ordinary double or triple hollow insulating glass and filling it with dry air or inert gas. The more partitions, the better the thermal insulation performance, usually glass. The use thickness is 3-10 mm. Therefore, each additional interlayer will increase the thickness of a transparent plate and frame, which will inevitably cause a significant increase in consumables and weight. As a result, the building door and window structure is required to improve the thermal insulation performance. The mezzanine setting will increase the building's own weight. In addition to the inconvenience of installation and use, it will also bring building doors. The increase in window-related accessories and building costs, even if ultra-white glass with a transmittance of 90% is used, the light transmission performance of each additional interlayer decreases at least about 10%. It is also not good for heating and energy saving performance that improves the solar heat gain coefficient. Therefore, the number of interlayers is generally increased to three at most, and rarely exceeds three.

After the insulation of hollow glass, a method of honeycomb structure was developed to suppress convection and increase the thickness of the gas spacer layer. The hydraulic diameter of the honeycomb structure is generally 5-10 mm, and the thickness is generally more than 25 mm. Although its thermal insulation effect is good However, the light transmittance is low, the visual comfort is poor, and the complicated manufacturing cost is high, so the development is slow. In addition, a vacuum pumping method is also used to reduce conduction heat transfer. Generally, vacuum glass is 15-18% more energy efficient than insulating glass, but the manufacturing process is complicated and the cost is high. For example, CN93228540 has announced a "universal vacuum insulation glass", which uses double-layer glass and vacuum, and a set of transparent PVC hard plastic grids is set between the interlayers, and the periphery is bonded with epoxy adhesive with higher bonding strength. The glass strip is convenient for sealing and holding during vacuuming, and prevents air convection and leakage in the interlayer. Using this method, the grid will significantly reduce the light transmittance, especially in high-rise buildings. It also significantly increases the ground structure. The influence of the total weight on the foundation cannot be ignored. Thirdly, due to the different expansion coefficients of PVC and epoxy glue, and the epoxy glue has no elasticity after curing, after a period of cold and heat alternating stress cycles, it will inevitably be more The relaxation of the closed structure occurs quickly, leading to the failure of the vacuum degree, so the life and reliability of the insulation are low. In addition, due to the large negative pressure in the vacuum glass, it is usually not suitable for occasions such as high-rise buildings with high wind pressure. use.

Convective heat transfer accounts for approximately 3%, and its value depends on the thickness and temperature of the glass gas spacer.

Generally, heat insulation means that doors and windows prevent indoor and outdoor heat transfer in winter. Insulation is the opposite. It means that doors and windows prevent heat transfer from indoor to indoor heat in summer. It mainly depends on the ability to block sunlight. To achieve both thermal insulation and thermal insulation performance through technology combination The direction of the two-way performance of temperature and heat insulation is developed, and at the same time, the cost is low, and the cost performance of high heat insulation and heat insulation is measured. In terms of double-layer / insulating glass, it is a technological breakthrough and development direction to realize the energy conservation of conductive heat transfer and convective heat transfer technology in addition to radiation, and the use of solar energy to achieve building heating and energy conservation. Summary of the invention

The second aspect of the present invention is to provide a heat-insulating and transparent plate for building energy conservation, which includes a hollow heat-insulating and transparent plate, and a plurality of horizontally parallel and highly transparent polymer plates are arranged in a transparent plate sandwich of the heat-insulating and transparent plate. The lipid soft film wing constitutes a convective heat transfer blocker that does not substantially affect the light transmission. Therefore, it is possible to increase the distance between the transparent plate sandwiches without increasing the size of the convection distance that normally occurs, and increase the distance of lateral static air heat transfer. The heat loss coefficient makes it reach the heat loss coefficient of the existing coated insulating glass, and improves the solar heat gain coefficient, and achieves excellent reliability and excellent cost performance ratio.

The present invention is achieved through the following technical solutions. The present invention adopts a heat-insulating and transparent plate, which includes a transparent plate and an edge frame. A double-layer transparent plate composed of two transparent plates can be provided with a sealing tape or a space between the edges. Strips and sealants make the interlayer airtight with the outside world. The interlayer is filled with a suitable gas such as dry air or inert gas that suppresses up and down convection or can reduce the heat transfer coefficient. It is characterized in that the interlayer also includes a plurality of horizontal parallel The provided transparent fins and transparent fins are fixed on both sides of the inner frame of the interlayer, and the transparent fin refers to a highly transparent polyester polymer plastic film having a thickness of less than 0.15 mm, and when the interlayer distance is between When the optimum value is 16-60 mm, the optimum value range corresponding to the transparent fin spacing is 4-17 mm. Highly transparent polyester polymer plastic film is: highly transparent polyurethane (PU) soft film or highly transparent polycarbonate (PC) soft film or highly transparent polyester (PET) soft film Chemical film with a rate of at least 80%, UV-resistant, and long-term continuous service life. Under the condition that the high-transparent polyester polymer plastic film satisfies 80% light transmittance, the surface layer may be provided with a functional film, such as a broadband antireflection coating or a broadband anti-electromagnetic wave absorption film. The transparent fins are a plurality of parallel transparent fins formed by a continuous strip folded up and down and fixed on both sides of the inner frame of the sandwich in order. The soft film of the transparent wing is an elastic soft film or inelastic. Soft film, one end of the non-elastic soft film is fixedly connected to the side frame, and the other end is fixedly connected to the side frame through an elastic connecting member. The plurality of transparent fins arranged in parallel along the longitudinal direction may be arranged at equal intervals, or arranged at unequal intervals between the upper and lower ends and the middle portion. The width of the transparent fins should be set so that the distance between the transparent fins on both sides is not more than 5.2 mm. The interlayer distance refers to a suitable distance for thermal insulation between two transparent plates. The value is 8-200 mm. The optimal value for the interlayer distance is 16-60 mm. Under the condition that the total light transmittance is not less than 60%, the thermal insulation performance price ratio is better than the distance between the best sections. 5-40。 The ratio of the width (B) of the transparent fins to the spacing (δ) between them is between 1.5 and 40. One or more strips of the same material, performance, and thickness as the transparent fins can be connected to the horizontal plane of the transparent fins. The height of the downward hanging is 15% -50% of the transparent fin spacing. . The transparent plate may be composed of two single-layer or one single-layer and one double-layer hollow transparent plate units, and the transparent fins are arranged in two single-layers or one single-layer and one double-layer hollow transparent plate. Between units. The parallel arrangement of the transparent fins can be the parallel arrangement of its plane and the horizontal plane, or it can be changed between the plane and the horizontal plane according to different requirements such as thermal insulation or thermal insulation and the increase and decrease of geographic latitude.

Parallel setting of 0 ° to 75 °.

The advantages of the present invention are: The setting of a highly transparent polyester soft film convective heat transfer blocker can effectively prevent the vertical convection or reflow heat transfer of the longitudinal gas in the interlayer, and increase the size setting range of the air insulation layer spacing. Under the condition that the light transmission performance of the light-transmitting and heat-insulating plate is basically unchanged, the interlayer distance is increased, and the corresponding air insulation effect is also enhanced; the lateral static air heat transfer distance and damping are increased, and the insulation is significantly reduced. The thermal loss coefficient of the thermal insulation transparent plate makes it reach the level of the existing coated insulating glass, while maintaining the same solar heat gain coefficient as the vacuum glass, and has more stable thermal insulation reliability and excellent performance than the two Cost-price ratio.

A comparison of several specific application effects of the present invention is as follows: As the transmission loss of the multilayer light-transmitting plate structure is reduced, for the application of heat-insulating, transparent plates, according to one of its applications, such as: transparent materials are required for high light transmission In occasions such as window use, the thermal insulation and transparent plate than the honeycomb structure can greatly increase the light transmittance under the same thermal and thermal loss performance, and can maintain the same highest overall light transmittance as vacuum glass, visual comfort ratio The honeycomb structure and coated insulating glass are greatly improved, and the service life and thermal insulation reliability are greatly improved compared with vacuum insulation and coated hollow insulating transparent plate structure; and the number of transparent insulating layers is reduced to make the plate The weight is reduced, and the manufacturing and related costs are reduced. In addition, the complexity of its production and processing and the cost of use are also significantly lower than those of the vacuum insulation and honeycomb heat insulation transparent plates.

According to its second application: Chinese standard GB8484 for single-frame double-layer glass co-extruded steel-plastic casement window at 20 ° C. After comparative measurement, the following results are obtained: Single-frame double-layer glass co-extruded steel-plastic casement window Same type of wing-type casement window layer interval glass thickness 50% Evacuation layer interval wing interval glass thickness unit mm 6 3 plus closed Yu Tong 40 12. 5 3 Heat Loss factor

Plate 1 is made of ultra-white flat glass with a transmittance of 90% and a thickness of 4mm and 3mm, respectively, and a high-transparency acrylic sheet. The side frame 2 is composed of a hollow glass-aluminum spacer with a fixed stop or a support frame. Two pieces A composite sealant strip 4 or an aluminum spacer and a sealant 4 can be placed between the edges of the double-layer transparent plate that constitutes the sandwich, so that the sandwich is air-tight from the outside, and the sandwich is filled with anti-convection or can reduce the heat transfer coefficient. A suitable gas such as dry air or an inert gas (such as argon), a plurality of transparent fins arranged horizontally and horizontally in the interlayer adopt a continuous, highly transparent polyurethane (PU) soft film strip, strip It is an elastic soft film, which is folded up and down in the order of left and right and fixed on both sides of the inner frame of the sandwich as shown in Figure 1. The transparent wings are arranged at equal intervals, and the plane is set parallel to the horizontal plane. The transparent wings The thickness range of 0. 01- 0.15 implicitly taken as 0. 05mm thickness, light transmittance of 90%. According to experience, the width of the transparent fins should be set to be no more than 5.2 mm from the double transparent plates on both sides. Here, the distance between the transparent fins and the double transparent plates on both sides should be no more than 2.6 mm.

The interlayer distance refers to a suitable distance for thermal insulation between two transparent plates, and its value is 8- 200 mm. According to experience, the optimal value range is 16-60 mm. The optimal value refers to the distance between the best price and the best performance of the thermal insulation performance under the condition that the total light transmittance is not less than 60%. The thermal loss coefficient in the best section representing the thermal insulation performance is significantly better than the optimal value of the thermal loss coefficient of transparent insulating glass (glass uncoated) in the same size range of 2.5 (W / M ² K). In order to obtain a more comfortable visual effect, the ratio of the width (B) of the transparent fins and the arrangement pitch (δ) thereof should be between 1.5 and 40.

When the value of the transparent plate interval is 34-54mra, the corresponding transparent blade distance (δ) is 6-14 mm within its optimal range of 4-17 mm, and the transparent blade width (B) is 30-50 drawings. The ratio of the width of the fins to the distance between the fins is equal to 3.5-5. The best value of the overall light transmittance of the heat-insulating transparent plate is measured above 79%. It is similar to vacuum glass and slightly lower than the transparent hollow of the same setting. The optimal value of the overall light transmittance of the glass is 81%; the optimal value of the thermal loss coefficient can be lower than 1.8 (W / M), which is far better than the optimal value of the thermal loss coefficient of the transparent insulating glass in the same size range 2. 5 (W / M ² K).

In order to ensure the long-term high-transparent use effect, the high-transparent polymer plastic film refers to a light transmittance of at least 80%, anti-ultraviolet aging, and can maintain a high light transmittance under sunlight for a long-term continuous service life of more than 5 years. Chemical film.

As shown in FIG. 3, the second embodiment of the thermal insulation transparent plate of the present invention is composed of two transparent plates 1, a side frame 2, a flap 3, a sealant and an aluminum spacer 4, a partition 5 and the like. Insulating glass curtain wall, where: The side frame 2 is composed of an aluminum alloy frame, and a hollow glass aluminum partition with a fixed stop is arranged on the inner side of the side frame. Two transparent glasses are fixed and sealed. Two transparent plates 1 use float glass with a transmittance of 87% and a thickness of 10mm. The interlayer distance is 60 ΙΙ. The strip is a continuous high transparent polycarbonate (PC) non-elastic soft film. One end of the strip is fixedly connected to the side frame, and the other end is fixedly connected to the side frame through an elastic connecting member, and is fixed in parallel on both sides of the mezzanine window frame. A support strip frame may be provided in the middle of the strip to support the width. For the large glass surface and the middle part of the strip, the transparent fins are arranged at unequal intervals between the upper and lower ends and the middle part. Among them, the fins at the upper and lower ends are spaced apart from each other, and the fins at the middle part are spaced apart from each other. So the middle part The vision is more comfortable. The soft film strip wing 3 has the same material on the horizontal surface of the highly transparent front and rear separation strips 5 with a thickness of 0.15mm and a light transmittance of 90%. One side is folded with the midline of the wing plane through hot-melt bonding to form a downwardly-suspended separation strip connection structure as shown in Figure 3. The height of the downward hang is 15% -50% of the distance between the transparent fins. As a result, a damping or obstacle to the gas flow in the front-rear direction is provided to the upper part of each partitioning mezzanine. Such downwardly hanging partitioning strips may be one or more, depending on the spacing of the mezzanine; B) is 50mm, and the ratio of the width of the upper and lower ends of the fin and its middle portion to the arrangement pitch are 3. 125 and 4. 16. This can reduce the number of layers of the lower fins that pass through when part of the direct light enters, which is beneficial to maintaining the overall light transmission performance of the transparent plate.

The fins can be set in parallel with an angle of 0 ° -75 ° between the plane and the horizontal plane according to different requirements such as thermal insulation or thermal insulation, as well as the increase and decrease of geographic latitude. They are fixed in parallel on both sides of the mezzanine window frame. In summer, when the high temperature season is long, for low latitudes, choose a fin setting of 0 ° -5 ° and a light transmittance of 80%. It is beneficial for the incident light to pass through this transparent fin and be refracted into part of the diffused light into the room. Glare direct light; Another example is when the winter sunshine is weak; The low temperature season is long. For middle and high latitudes, such as Harbin, China, a highly transparent fin setting of about 45 ° can be used. Its advantages are: It is beneficial for the incident light to be as direct as possible. After passing through the interval of the highly transparent fins or after being partially refracted and transmitted by the highly transparent fins, it enters the room and obtains more indoor direct sunlight intensity while maintaining heat.

As shown in FIG. 4, the third embodiment of the heat-insulating transparent plate of the present invention is composed of two transparent plates 1, a side frame 2, a flap 3, a sealant and an aluminum spacer 4, and a composite sealant 6. The frame sandwich double glass heat-insulating translucent door, wherein the inside edge of the aluminum partition is provided with a baffle for fixing the wing strip, and the transparent plate 1 may be a single-layer glass and a double-layer hollow transparent plate unit such as a hollow. The glass is made of flat glass with a transmittance of 87% and a thickness of 8mm. The transparent fins are arranged between a single layer and a double-layered hollow transparent plate unit. The composite glass sealant 6 is used for hollow space in the hollow glass. And sealing, the side frame 2 is made of plastic, and aluminum spacers are placed between the single-layer glass and the insulating glass, which are respectively sealed between the butyl rubber and the glass, and fixed and sealed by the polysulfide rubber and the side frame 2; the wings 3 can be used 05mm ， The width of the light-transmitting wing ("PET") non-elastic soft film with a light transmittance of 90% and a certain degree of haze B) is 23m _m with wings and double sides The distance between layers of transparent plates is each 0.5 mm; the interval between sandwiches is 24 bands, the fin arrangement pitch (δ) is 8. 25mm, the ratio of the width of the fins to the arrangement pitch is 2. 78, and the plane of the fins and the horizontal plane are 45 The included angle is fixed in parallel to the aluminum partition fixing rails on both sides of the mezzanine door frame in the same manner as in the second embodiment. The advantage is that the 45 ° wing is used. Insulation can not only open the office environment to each other, but also block the visual interference to create a suitable working environment. In addition, the high-transparency polyester polymer plastic film can meet the requirements of 80% light transmittance, and the surface layer can be functional. For example, on the surface of polyester (PET) non-elastic soft film, a broadband anti-reflection coating with a nano-silica crosslinked network type or a broadband anti-electromagnetic wave absorption film provided by chemical surface modification treatment can be added to reduce Light pollution when used as external doors or windows or reduce the interference of outdoor electromagnetic waves on indoor working equipment.

To reduce the heat loss coefficient of thermal insulation and transparent plates such as doors and windows in the northern hemisphere and improve its solar heat gain system Several examples of heating and energy-saving applications illustrate the working principle of the heat-insulating and transparent plate of the present invention as follows: Except for 7.4% light reflection, the window surface of the outdoor noon sunlight in winter, enters the double-layer transparent plate sandwich, and the sunlight passes through the approximately parallel fins. After passing through the interlayer and entering the room through the inner transparent plate, as the height angle of the sun changes continuously, the sunlight is still refracted into the room after being refracted by the fins in some periods, so that the overall light transmittance can reach about 0.7. The indoor heat is conducted through the inner transparent plate to heat the air in the interlayer. The horizontal convection of the air and other air is blocked by the horizontally set fins, and the lateral heat conduction velocity of the air and other gases (with or without the barrier strip) is much smaller than the existence The speed of heat transfer during up and down convection, taking the fin-type transparent heat insulation hollow insulation plate layer interval of 40 _mm and the fin spacing of 12.5 mm as an example: its heat loss coefficient (W / M ² K) is higher than that of the sandwich without convection The double-layer transparent hollow insulation board with the largest interval, such as 6 and 9mm, can be reduced by about 30%.
