Abstract

This invention discloses a building glass curtain wall with dehumidification and heat preservation functions, including a frame, inner glass, outer glass, and a sandwich space between the inner and outer glass. A sealing ring is fitted around the outer edge of the sandwich space. The sealing ring contains two independent channels: a first channel and a second channel. The first channel is divided into an exhaust channel and an intake channel by a longitudinal partition, which are connected to a dehumidification circulation device via exhaust and intake interfaces, respectively. The second channel is connected to a micro-pump via an air nozzle. A heating element is fixed inside the sealing ring, and a power module is mounted on the frame. The dehumidification circulation device switches between dehumidification circulation and regeneration exhaust states via two three-way solenoid valves, achieving circulating dehumidification of the sandwich gas and online regeneration of the desiccant. This invention solves the technical problem of limited curtain wall life caused by the inability to regenerate online after desiccant adsorption saturation through the coordinated function of the channels within the sealing ring.

Description

Technical Field

[0001] This invention relates to the field of building glass curtain wall technology, and in particular to a building glass curtain wall with dehumidification and heat preservation functions. Background Technology

[0002] Insulating glass curtain walls are widely used in modern building facades due to their excellent thermal and sound insulation properties. An insulated glass unit consists of two layers of glass, an inner and an outer layer, and a space between them. The outer edge of the space is sealed with a gasket. To ensure long-term dryness inside the space, current technology typically fills the gasket or spacer with solid desiccants such as molecular sieves to absorb water vapor that slowly seeps through the seal. However, with increasing service life, the gasket faces issues such as material aging and temperature fatigue, leading to a gradual decline in sealing performance and making it easier for external moisture to penetrate. To address this degradation in sealing performance, existing solutions include inflatable cavities within the gasket. Inflating these cavities causes the gasket to expand, increasing the contact pressure between the gasket and the glass surface. Both desiccant adsorption and gas-filled sealing enhancement are used in existing insulated glass curtain walls, but they are usually implemented as independent functional modules.

[0003] However, in existing technologies, the desiccant adsorption and sealing enhancement functions are independent and lack synergy, leading to a fundamental technical problem: the desiccant's adsorption capacity is limited, and once saturated, it signifies the end of the functional lifespan of the insulated glass. Existing gas-filled sealing structures can only increase sealing pressure to delay moisture infiltration, but cannot actively remove existing moisture within the interlayer or regenerate the saturated desiccant. Although some solutions propose regenerating saturated desiccant through heating, the desorbed water vapor during regeneration must be discharged through the ventilation duct connecting the interlayer, posing a risk of reverse moisture infiltration and hindering reliable desiccant regeneration. Therefore, insulated glass curtain walls lack effective means to maintain dryness within the interlayer after desiccant saturation, and their lifespan is limited by the desiccant's adsorption capacity. Summary of the Invention

[0004] The purpose of this invention is to provide a building glass curtain wall with dehumidification and heat preservation functions, so as to solve the problems of limited desiccant adsorption capacity, product life end after saturation and lack of effective regeneration methods in existing insulated glass curtain walls.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A building glass curtain wall with dehumidification and heat preservation functions includes a frame, inner glass, outer glass, and a sandwich space disposed between the inner glass and the outer glass. The outer edge of the sandwich space is fitted with a sealing ring, which is fixedly connected to the frame. The sealing ring has a first channel and a second channel that are independent of each other and do not communicate with each other. A partition wall is integrally formed between the first channel and the second channel. The first channel and the second channel are both arranged in a ring extending circumferentially along the sealing ring.

[0007] A longitudinal partition is fixedly installed inside the first channel, which divides the first channel along its length into an independent exhaust channel and an intake channel.

[0008] The frame is fixedly provided with an exhaust port, an air inlet, and an air nozzle. The exhaust port is connected to the exhaust flow channel, the air inlet is connected to the air inlet flow channel, and the air nozzle is connected to the second channel.

[0009] A heating element is fixedly mounted on the side of the sealing ring facing the interlayer space. A power module is mounted on the frame. The heating element is electrically connected to the power module. The power module can be connected to an external power source and provide working power to the electrical components of the curtain wall.

[0010] Based on the above technical solution, the present invention can be further improved as follows.

[0011] Furthermore, a dehumidification circulation device and a micro air pump are fixedly mounted on the frame. The two fluid ports of the dehumidification circulation device are respectively sealed and connected to the exhaust port and the air inlet port. The output end of the micro air pump is sealed and connected to the air nozzle.

[0012] Furthermore, an exhaust pipe, an intake pipe, and an air delivery pipe are embedded and fixed inside the lower end of the frame; one end of the exhaust pipe passes through the side wall of the sealing ring and is connected to the exhaust flow channel, and the other end of the exhaust pipe is connected to the exhaust interface; one end of the intake pipe passes through the side wall of the sealing ring and is connected to the intake flow channel, and the other end of the intake pipe is connected to the intake interface; one end of the air delivery pipe is connected to the inner cavity of the second channel, and the other end of the air delivery pipe is connected to the air nozzle.

[0013] Furthermore, the inner wall of the exhaust channel is provided with a plurality of exhaust holes communicating with the interlayer space, and the inner wall of the intake channel is provided with a plurality of intake holes communicating with the interlayer space; the exhaust holes and the intake holes are both arranged on the wall surface of the sealing ring facing the interlayer space, and are located outside the coverage area of ​​the heating element.

[0014] Furthermore, a number of the exhaust holes are arranged at intervals along the circumference of the sealing ring in the area at the bottom of the corresponding interlayer space, and a number of the air inlets are arranged at intervals along the circumference of the sealing ring in the area at the top of the corresponding interlayer space.

[0015] Furthermore, the sealing ring has a trapezoidal cross-section structure, and the upper and lower edges of the sealing ring facing the inner glass are integrally formed with a first upper sealing lip and a first lower sealing lip, respectively. The upper and lower edges of the sealing ring facing the outer glass are integrally formed with a second upper sealing lip and a second lower sealing lip, respectively. The second channel can undergo radial expansion deformation in the inflated state to push each sealing lip to move and fit towards the corresponding inner and outer glass surfaces.

[0016] Furthermore, the heating element includes an elastic metal plate and a heating layer. The elastic metal plate is fixedly attached to the side wall of the sealing ring facing the interlayer space, and the heating layer is fixedly attached to the surface of the elastic metal plate. The heating layer adopts a resistive heating structure, and the electrodes of the heating layer are electrically connected to the power module through wires.

[0017] Furthermore, the dehumidification circulation device includes a housing, a circulation pump, and a drying tank. Both the circulation pump and the drying tank are fixedly installed inside the housing. The circulation pump's inlet is equipped with a first three-way solenoid valve. The common end of the first three-way solenoid valve is connected to the circulation pump's inlet. The first selector end of the first three-way solenoid valve is connected to the exhaust port via a first pipe. The second selector end of the first three-way solenoid valve is connected to a regeneration inlet pipe, the end of which is connected to the outside atmosphere. The circulation pump's outlet is connected to the drying tank's inlet. The drying tank's outlet is equipped with a second three-way solenoid valve. The common end of the second three-way solenoid valve is connected to the drying tank's outlet. The first selector end of the second three-way solenoid valve is connected to the inlet port via a second pipe. The second selector end of the second three-way solenoid valve is connected to a regeneration exhaust pipe, the end of which is connected to the outside atmosphere.

[0018] Furthermore, the drying tank is surrounded by heating pipes, which are matched with a heating module, and the heating module is electrically connected to the power module; the drying tank is filled with renewable solid desiccant.

[0019] Furthermore, the sealing ring has a sensor mounting groove on the inner wall facing the interlayer space. A temperature and humidity sensor is embedded and fixed in the sensor mounting groove. The detection probe of the temperature and humidity sensor extends into the interlayer space and is positioned near the inner surface of the outer glass.

[0020] Furthermore, the frame is equipped with a controller, which is electrically connected to the temperature and humidity sensor, the miniature air pump, the circulation pump, the first three-way solenoid valve, the second three-way solenoid valve, the heating module, and the power module; the power module provides operating power to the temperature and humidity sensor, the miniature air pump, the circulation pump, the first three-way solenoid valve, and the second three-way solenoid valve.

[0021] Furthermore, the controller is equipped with dew point calculation logic. The controller receives the temperature T and relative humidity RH of the interlayer space collected by the temperature and humidity sensor, and calculates the dew point temperature Td according to the following formula: in, , ;

[0022] The controller has a first preset temperature difference and a second preset temperature difference. When the detected T−Td≤the first preset temperature difference, the controller controls the power module to supply power to the heating layer and controls the circulation pump to start running. When the detected T−Td≥the second preset temperature difference, the controller controls the heating layer to be powered off and the circulation pump to stop running.

[0023] Furthermore, the controller has a built-in working time statistics unit and a regeneration trigger threshold. The controller accumulates and records the effective working time of the dehumidification circulation device. When the accumulated working time reaches the regeneration trigger threshold, the controller controls the first three-way solenoid valve to switch to the common terminal and the second selection terminal to conduct, and the second three-way solenoid valve to switch to the common terminal and the second selection terminal to conduct. At the same time, the controller controls the power module to power the heating module, so that the heating module heats the solid desiccant inside the drying tank.

[0024] Furthermore, the controller has a third preset temperature and is connected to an outdoor ambient temperature detection signal. When the outdoor ambient temperature is lower than the third preset temperature, the controller controls the micro air pump to start, filling the second channel with gas, causing the second channel to undergo radial expansion deformation.

[0025] Compared with the prior art, the embodiments of the present invention have at least the following beneficial effects:

[0026] This invention provides a physical basis for the active circulation of gas within the interlayer by setting independent first and second channels inside the sealing ring, and dividing the first channel into an exhaust channel and an intake channel by a longitudinal partition. This enables the directional extraction of moisture from the interlayer and the directional return of dry gas, changing the traditional "sealing is static sealing" technical mode of insulated glass. Furthermore, the dehumidification circulation device, controlled by two three-way solenoid valves, allows the system to switch between dehumidification circulation and regeneration exhaust states. This achieves both active circulation and dehumidification of the gas inside the interlayer and online heating and regeneration of the desiccant. During regeneration, the interlayer is isolated from the external gas path, effectively preventing the reverse flow of external moisture. The risk of condensation is eliminated, meaning the lifespan of the insulated glass curtain wall is no longer limited by the adsorption capacity of the desiccant. Simultaneously, the heating element on the sealing ring can radiate heat to the interlayer when needed, working in synergy with the active dehumidification function. Furthermore, this invention uses a temperature and humidity sensor embedded inside the sealing ring to monitor the interlayer temperature T and relative humidity RH in real time. The controller calculates the dew point temperature Td based on this and compares the difference in real time, enabling proactive prediction and precise intervention of the risk of condensation in the interlayer. The controller also automatically triggers the regeneration program by statistically analyzing the cumulative working time of the dehumidification cycle, achieving a shift from "passive failure" to "active regeneration," thus realizing the long-term and intelligent dehumidification and insulation function of the insulated glass curtain wall.

[0030] The present invention will now be described in further detail with reference to the accompanying drawings.

[0031] Please refer to the following: Figures 1 to 10 In an optional embodiment of this application, a building glass curtain wall with dehumidification and heat preservation functions is provided, including a frame 1, inner glass 2, outer glass 3, and a sandwich space 4 disposed between the inner glass 2 and the outer glass 3. A sealing ring 5 is fitted to the outer edge of the sandwich space 4, and the sealing ring 5 is fixedly connected to the frame 1. The sealing ring 5 has an independent first channel 51 and a second channel 52 inside, wherein a partition wall 53 is integrally formed between the first channel 51 and the second channel 52. Both the first channel 51 and the second channel 52 extend circumferentially along the sealing ring 5. The first channel 51... The frame 1 has an internal longitudinal partition 54, which divides the first channel 51 along its length into an independent exhaust channel 51a and an intake channel 51b. A heating element 14 is fixedly connected to the side of the sealing ring 5 facing the interlayer space 4. An exhaust port 6, an intake port 7, and a nozzle 8 are integrated on the inner side wall of the frame 1. The exhaust port 6 is connected to the exhaust channel 51a, the intake port 7 is connected to the intake channel 51b, and the nozzle 8 is connected to the second channel 52. A power module 16 is also installed on the inner side wall of the frame 1. The power module 16 is used to connect to an external power source and provide working power.

[0032] Specifically, the frame 1 serves as the supporting skeleton of the entire curtain wall unit. It is made of aluminum alloy or steel profiles and has a rectangular frame shape. It has sufficient structural strength and rigidity to bear the weight of the inner glass 2 and the outer glass 3 as well as wind loads. The inner glass 2 faces the indoor side, and the outer glass 3 faces the outdoor side. A predetermined distance is maintained between the two to form a mezzanine space 4. The thickness of the mezzanine space 4 is usually 6mm to 20mm. The mezzanine space 4 is filled with dry air or inert gas (such as argon or krypton) to improve the thermal insulation performance of the curtain wall.

[0033] The sealing ring 5 is located at the outer edge of the interlayer space 4, extending circumferentially along the frame 1 in a rectangular closed ring shape. The sealing ring 5 is made of thermally conductive silicone or EPDM rubber, possessing good elasticity and aging resistance, and is fixedly connected to the frame 1 through vulcanization or bonding. It is understood that the elastic properties of the sealing ring 5 enable it to form a reliable elastic sealing boundary between the inner glass 2 and the outer glass 3, while allowing controllable elastic deformation under inflated conditions.

[0034] Please refer to the following: Figure 3 and Figure 4 Inside the sealing ring 5, there are two independent channels, a first channel 51 and a second channel 52. These channels are airtightly separated by an integrally formed partition wall 53, preventing cross-contamination of the gases within them. Both channels extend circumferentially around the sealing ring 5, forming a closed annular flow channel around the interlayer space 4. It should be noted that the first channel 51 and the second channel 52 are arranged radially inwards and outwards in the cross-section of the sealing ring 5. The first channel 51 is located radially outwards (closer to the interlayer space 4), and the second channel 52 is located radially inwards (closer to the frame 1). They occupy different positions in the width direction of the sealing ring 5 and do not overlap. This radial inward-outward arrangement minimizes the gas exchange path between the first channel 51 and the interlayer space 4, and also allows the second channel 52 to more effectively transmit thrust to the sealing lip of the sealing ring 5 during inflation.

[0035] Please refer to the following: Figure 3 , Figure 4 , Figure 5 and Figure 6The first channel 51 is internally equipped with a longitudinal partition 54, which is integrally extruded with the sealing ring 5. The longitudinal partition 54 extends along the length (i.e., circumferential direction) of the first channel 51, dividing the internal space of the first channel 51 into two independent sub-channels: an exhaust channel 51a and an intake channel 51b. The exhaust channel 51a and the intake channel 51b are airtightly isolated from each other, each performing a single-direction fluid transport function. The exhaust channel 51a is used to exhaust moisture from the interlayer space 4, while the intake channel 51b is used to introduce dried gas into the interlayer space 4. It can be understood that by dividing the first channel 51 into the exhaust channel 51a and the intake channel 51b through the longitudinal partition 54, the gas in the interlayer space 4 can form a directional flow. Moisture in the interlayer space 4 is extracted from the exhaust channel 51a, and dried gas is introduced from the intake channel 51b. The two are completely separated spatially, avoiding the mixing of intake and exhaust airflows in the same channel, thereby improving the efficiency of the dehumidification cycle.

[0036] Please refer to the following: Figure 7 , Figure 8 and Figure 9 The inner wall of the frame 1 is integrated with an exhaust port 6, an air inlet port 7, and an air nozzle 8. The exhaust port 6 is connected to the exhaust flow channel 51a through a pipe inside the frame 1, the air inlet port 7 is connected to the air inlet flow channel 51b through a pipe inside the frame 1, and the air nozzle 8 is connected to the second channel 52 through a pipe inside the frame 1. The exhaust port 6, air inlet port 7, and air nozzle 8 are integrated into the inner wall of the frame 1, which facilitates the quick docking and installation of the dehumidification circulation device 9 and the micro air pump 10, so as to achieve quick insertion and removal of the pipes and reliable sealing.

[0037] Please see Figure 3 and Figure 4 A heating element 14 is fixedly connected to the side of the sealing ring 5 facing the interlayer space 4. The heating element 14 is in the form of a thin sheet or strip, extends circumferentially along the sealing ring 5, and covers at least a portion of the inner wall of the sealing ring 5. The heating element 14 is electrically connected to the power module 16, which provides it with operating power. It is understood that the heating element 14 is positioned on the side of the sealing ring 5 facing the interlayer space 4 so that the heat it generates can be directly radiated into the interior of the interlayer space 4, thereby rapidly increasing the glass surface temperature and effectively preventing condensation. It should be noted that the heating element 14 is disposed on the wall surface of the sealing ring 5 facing the interlayer space 4, and the exhaust port 55 and the air inlet port 56 are located outside the coverage area of ​​the heating element 14. That is, the exhaust port 55 and the air inlet port 56 are arranged side by side with the heating element 14 on the wall surface of the sealing ring 5 and do not overlap with each other, so that the gas in the interlayer space 4 can freely enter and exit the exhaust channel 51a and the air inlet channel 51b through the exhaust port 55 and the air inlet port 56 without being obstructed by the heating element 14.

[0038] Please see Figure 1 The frame 1 is also equipped with a power module 16. The power module 16 is used to convert external power (such as AC220V mains power or low-voltage DC power) into the working voltage required by various electrical components of the curtain wall, and to provide stable working power to components such as the heating element 14, controller 17, micro air pump 10, circulation pump 92, temperature and humidity sensor 15, first three-way solenoid valve 94, second three-way solenoid valve 97, and heating module 911. Exemplarily, the power module 16 may include an AC-DC conversion circuit, a voltage regulation circuit, and an overcurrent protection circuit, and its output terminal is connected to the power supply terminal of each electrical component through wires. In a specific application scenario, the power module 16 converts AC220V mains power into two voltage outputs: DC24V and DC5V. The DC24V is used to drive the micro air pump 10 and circulation pump 92, and the DC5V is used to power the controller 17 and temperature and humidity sensor 15.

[0039] With the above configuration, the hollow glass curtain wall provided in this embodiment constructs a first channel 51 and a second channel 52 that are independent of each other and have clear functional divisions within the sealing ring 5. In the first channel 51, an exhaust channel 51a and an intake channel 51b are formed by a longitudinal partition 54, realizing the physical basis for directional flow and circulating dehumidification of gas in the interlayer space 4. This enables the active dehumidification of gas in the interlayer space 4 and online regeneration of desiccant in conjunction with the dehumidification circulation device 9.

[0040] Please refer to the following: Figure 1 and Figure 7 In an optional embodiment of this application, a dehumidification circulation device 9 and a micro air pump 10 are assembled inside the frame 1. The two fluid ports of the dehumidification circulation device 9 are respectively sealed and connected to the exhaust port 6 and the air inlet port 7. The output end of the micro air pump 10 is sealed and connected to the air nozzle 8.

[0041] Specifically, the dehumidification circulation device 9 is fixedly installed on the inner wall of the frame 1 (i.e., the side facing the room) or in the reserved installation space at the bottom of the frame 1, its position facilitating daily maintenance and pipeline connection. The dehumidification circulation device 9 has two fluid ports, which are used to connect the exhaust port 6 and the air inlet port 7 respectively, forming a docking connection with the exhaust flow channel 51a and the air inlet flow channel 51b inside the sealing ring 5. The micro air pump 10 is also fixedly installed on the inner wall of the frame 1, and its output end is connected to the air nozzle 8 through an air pipe for sealing and charging the second channel 52 to achieve enhanced sealing. It can be understood that the dehumidification circulation device 9, together with the exhaust flow channel 51a and the air inlet flow channel 51b, forms a closed gas circulation loop, allowing the moisture in the interlayer space 4 to be extracted, dehumidified, and then returned to the interlayer space 4, thereby achieving continuous circulation and drying of the gas inside the interlayer. Meanwhile, the micro air pump 10, as an independent inflation actuator, is controlled by the controller 17 based on the outdoor temperature signal. It can actively adjust the air pressure in the second channel 52 according to changes in ambient temperature, thereby achieving adaptive adjustment of sealing performance.

[0042] Please refer to the following: Figure 7 , Figure 8 and Figure 9 In an optional embodiment of this application, an exhaust pipe 11, an intake pipe 12, and an air supply pipe 13 are embedded and fixed inside the lower end of the frame 1; wherein one end of the exhaust pipe 11 passes through the side wall of the sealing ring 5 and is connected to the exhaust flow channel 51a, and the other end of the exhaust pipe 11 is sealed and connected to the exhaust interface 6; one end of the intake pipe 12 passes through the side wall of the sealing ring 5 and is connected to the intake flow channel 51b, and the other end of the intake pipe 12 is sealed and connected to the intake interface 7; one end of the air supply pipe 13 is connected to the inner cavity of the second channel 52, and the other end of the air supply pipe 13 is sealed and connected to the air nozzle 8.

[0043] Specifically, the lower end of the frame 1 has a pre-set mounting hole or mounting groove extending longitudinally, in which the exhaust pipe 11, the intake pipe 12, and the air supply pipe 13 are respectively embedded and fixed. One end of the exhaust pipe 11 passes through the bottom side wall of the sealing ring 5 and extends into the exhaust channel 51a, making the exhaust pipe 11 connected to the internal space of the exhaust channel 51a; the other end of the exhaust pipe 11 is connected to the inner port of the exhaust interface 6, and is connected to the external dehumidification circulation device 9 through the exhaust interface 6. One end of the intake pipe 12 passes through the bottom side wall of the sealing ring 5 and extends into the intake channel 51b, making the intake pipe 12 connected to the internal space of the intake channel 51b; the other end of the intake pipe 12 is connected to the inner port of the intake interface 7, and is connected to the external dehumidification circulation device 9 through the intake interface 7. One end of the air supply pipe 13 passes through the bottom side wall of the sealing ring 5 and extends into the interior of the second channel 52, so that the air supply pipe 13 is connected to the interior space of the second channel 52; the other end of the air supply pipe 13 is connected to the inner port of the air nozzle 8, and is connected to the external micro air pump 10 through the air nozzle 8.

[0044] For example, the exhaust pipe 11, intake pipe 12, and air supply pipe 13 are all copper or stainless steel pipes, and their outer walls are airtightly sealed to the mounting holes of the frame 1 using sealant or O-rings. It is understood that by independently configuring the exhaust pipe 11, intake pipe 12, and air supply pipe 13, the exhaust channel 51a, intake channel 51b, and second channel 52 each have independent pipeline connection paths, avoiding cross-contamination of the three different functional gases inside the frame 1 and ensuring the independence and reliability of their respective functions.

[0045] Please refer to the following: Figure 2 , Figure 3 and Figure 4 In an optional embodiment of this application, the inner wall of the exhaust channel 51a is provided with a plurality of exhaust holes 55 communicating with the interlayer space 4, and the plurality of exhaust holes 55 are equidistantly arranged along the sealing ring 5 in the area corresponding to the bottom of the interlayer space 4; the inner wall of the inlet channel 51b is provided with a plurality of inlet holes 56 communicating with the interlayer space 4, and the plurality of inlet holes 56 are equidistantly arranged along the sealing ring 5 in the area corresponding to the top of the interlayer space 4; the circumferential directions of the exhaust holes 55 and the inlet holes 56 are both located outside the coverage area of ​​the heating element 14.

[0046] Specifically, the inner wall of the exhaust channel 51a (i.e., the wall facing the interlayer space 4) is provided with multiple exhaust holes 55. Each exhaust hole 55 penetrates the inner wall of the sealing ring 5, connecting the exhaust channel 51a to the interlayer space 4. The multiple exhaust holes 55 are arranged at equal intervals along the circumference of the sealing ring 5, and are all located in the bottom region of the interlayer space 4. The inner wall of the inlet channel 51b is provided with multiple inlet holes 56. Each inlet hole 56 penetrates the inner wall of the sealing ring 5, connecting the inlet channel 51b to the interlayer space 4. The multiple inlet holes 56 are arranged at equal intervals along the circumference of the sealing ring 5, and are all located in the top region of the interlayer space 4. The exhaust holes 55 and inlet holes 56 are arranged side by side with the heating element 14 on the inner wall of the sealing ring 5, without overlapping each other. Understandably, the exhaust vent 55 is located at the bottom of the interlayer space 4, and the air inlet vent 56 is located at the top of the interlayer space 4, forming a directional airflow organization of "bottom extraction and top delivery". Since the relative density of moisture in the interlayer space 4 is relatively high, it tends to accumulate in the bottom area. Positioning the exhaust vent 55 at the bottom allows for the priority extraction of the most humid gas, improving dehumidification efficiency. After being delivered from the top, the dry gas diffuses downwards through the entire interlayer space, allowing for more thorough mixing with the gas within the interlayer and displacing the moisture. This layout fully utilizes the principle of natural gas stratification, optimizing the dehumidification circulation effect. The exhaust vent 55 and air inlet vent 56 are located outside the coverage area of ​​the heating element 14, ensuring that the vents are not blocked and that gas can freely enter and exit.

[0047] Please refer to the following: Figure 5 and Figure 6 In an optional embodiment of this application, the sealing ring 5 has a trapezoidal cross-section, wherein the upper and lower edges of the sealing ring 5 facing the inner glass 2 are integrally formed with a first upper sealing lip 57a and a first lower sealing lip 57b, respectively, and the upper and lower edges of the sealing ring 5 facing the outer glass 3 are integrally formed with a second upper sealing lip 58a and a second lower sealing lip 58b, respectively; the second channel 52 expands radially outward in the inflated state and pushes the first upper sealing lip 57a, the first lower sealing lip 57b, the second upper sealing lip 58a, and the second lower sealing lip 58b toward the corresponding glass surface.

[0048] Specifically, the sealing ring 5 has a trapezoidal cross-section, meaning its radially outer width (towards the interlayer space 4) is smaller than its radially inner width (towards the frame 1), forming a wedge-shaped cross-sectional profile. On the surface of the sealing ring 5 facing the inner glass 2, a first upper sealing lip 57a and a first lower sealing lip 57b are integrally formed at their upper and lower edges, respectively. On the surface of the sealing ring 5 facing the outer glass 3, a second upper sealing lip 58a and a second lower sealing lip 58b are integrally formed at their upper and lower edges, respectively. The second channel 52 is located radially inner to the sealing ring 5, and its cross-sectional shape is circular or elliptical. When gas is injected into the second channel 52 via the micro air pump 10, the air pressure inside the second channel 52 increases, and its cross-sectional dimensions expand radially outward. The expansion force causes the sealing ring 5 to undergo elastic deformation radially outward (i.e., towards the inner glass 2 and outer glass 3), causing the first upper sealing lip 57a, the first lower sealing lip 57b, the second upper sealing lip 58a, and the second lower sealing lip 58b to tightly adhere to the surfaces of the inner glass 2 and the outer glass 3, respectively. It can be understood that the trapezoidal cross-section of the sealing ring 5 and the multi-lip structure design allow each sealing lip to undergo directional displacement towards the glass surface when the second channel 52 is inflated, thereby forming multiple sealing interfaces between the glass and the sealing ring, effectively improving the reliability of the seal. It should be noted that this multi-lip distribution means that independent sealing lips are provided on the upper and lower edges of the sealing ring 5 towards each piece of glass, allowing the sealing ring 5 to form sealing contact simultaneously in both the thickness and width directions of the glass when inflated, improving the redundancy of the seal and its resistance to aging.

[0049] Please refer to the following: Figure 3 , Figure 4 and Figure 6In an optional embodiment of this application, the heating element 14 includes an elastic metal plate 141 and a heating layer 142, wherein the elastic metal plate 141 is fixedly attached to the middle position of the side wall of the sealing ring 5 facing the interlayer space 4, and the heating layer 142 is attached and fixed to the outer surface of the elastic metal plate 141. The heating layer 142 adopts a resistive heating structure, and the electrodes of the heating layer 142 are electrically connected to the power module 16 through wires.

[0050] Specifically, the heating element 14 is composed of an elastic metal plate 141 and a heating layer 142. The elastic metal plate 141 is made of a thin metal plate with good elasticity and thermal conductivity, such as a beryllium bronze plate or a stainless steel plate. The elastic metal plate 141 is fixedly attached to the inner wall of the sealing ring 5 facing the interlayer space 4 by vulcanization bonding or mechanical pressing, extending along the circumference of the sealing ring 5 and covering the inner wall area of ​​the sealing ring 5. Because the elastic metal plate 141 is elastic, it can produce corresponding elastic bending with the deformation of the sealing ring 5, and always maintains a close fit with the inner wall of the sealing ring 5. The heating layer 142 is attached and fixed to the outer surface of the elastic metal plate 141 facing the interlayer space 4, and adopts a resistance heating structure. Exemplarily, the heating layer 142 can be a graphene electrothermal film, a carbon crystal electrothermal film, or a metal resistance wire heating layer. Electrodes are respectively provided at both ends of the heating layer 142, and the electrodes are electrically connected to the output terminal of the power module 16 through wires. When the power module 16 supplies power to the heating layer 142, the heating layer 142 generates Joule heat. This heat is transferred through the elastic metal plate 141 and radiated into the interior of the interlayer space 4. Understandably, due to the high thermal conductivity of the elastic metal plate 141, it can rapidly and evenly conduct the heat generated by the heating layer 142 to its covered area, forming a planar heat source that radiates heat into the interlayer space 4, thereby quickly raising the temperature inside the interlayer space 4 and effectively preventing condensation on the glass surface. It should be noted that the elastic metal plate 141 is attached to the inner wall of the sealing ring 5 and deforms synchronously with the sealing ring 5, avoiding the risk of the rigid heating element detaching or being damaged when the sealing ring deforms, thus improving the long-term reliability of the heating element.

[0051] Please see Figure 10In an optional embodiment of this application, the dehumidification circulation device 9 includes a housing 91, a circulation pump 92, and a drying tank 93, wherein the circulation pump 92 and the drying tank 93 are both fixedly installed inside the housing 91; the air inlet end of the circulation pump 92 is equipped with a first three-way solenoid valve 94, wherein the common end of the first three-way solenoid valve 94 is connected to the air inlet end of the circulation pump 92, the first selection end of the first three-way solenoid valve 94 is sealed and connected to the exhaust port 6 through a first pipe 95, and the second selection end of the first three-way solenoid valve 94 is connected to a regeneration air inlet pipe 96. 6. The air outlet of the circulating pump 92 is sealed and connected to the air inlet of the drying tank 93. The air outlet of the drying tank 93 is equipped with a second three-way solenoid valve 97. The common end of the second three-way solenoid valve 97 is connected to the air outlet of the drying tank 93. The first selection end of the second three-way solenoid valve 97 is sealed and connected to the air inlet 7 through the second pipeline 98. The second selection end of the second three-way solenoid valve 97 is connected to the regeneration exhaust pipe 99. The end of the regeneration exhaust pipe 99 penetrates the housing 91 and extends outward to connect to the outside atmosphere.

[0052] Specifically, the dehumidification circulation device 9 includes a housing 91, a circulation pump 92, and a drying tank 93. The housing 91 is a closed shell structure, fixedly installed on the inner wall of the frame 1. The housing 91 has an internal chamber for accommodating the circulation pump 92 and the drying tank 93. The housing 91 has through holes for pipes to pass through. Both the circulation pump 92 and the drying tank 93 are fixedly installed inside the housing 91. The circulation pump 92 drives the gas to flow in the circulation loop, and the drying tank 93 adsorbs moisture from the flowing gas.

[0053] The air inlet of the circulation pump 92 is equipped with a first three-way solenoid valve 94. The first three-way solenoid valve 94 is a two-position three-way solenoid valve with one common end and two selectable ends. The common end of the first three-way solenoid valve 94 is sealed and connected to the air inlet of the circulation pump 92 through a pipeline. The first selectable end of the first three-way solenoid valve 94 is sealed and connected to the exhaust port 6 through the first pipeline 95, thereby realizing the connection with the exhaust flow channel 51a inside the sealing ring 5. The second selectable end of the first three-way solenoid valve 94 is connected to a regeneration air inlet pipe 96. The regeneration air inlet pipe 96 passes through the housing 91 and extends outward. Its end is connected to the outside atmosphere. An air filter can be installed at the end of the regeneration air inlet pipe 96 to prevent external dust from entering the pipe.

[0054] The outlet of the circulating pump 92 is sealed to the inlet of the drying tank 93 via a pipeline. The drying tank 93 is a sealed container filled with a regenerable solid desiccant (such as molecular sieves, silica gel, etc.) to adsorb moisture in the gas flowing through it. The outlet of the drying tank 93 is equipped with a second three-way solenoid valve 97, which is also a two-position three-way solenoid valve. Its common end is sealed to the outlet of the drying tank 93 via a pipeline. The first selection end of the second three-way solenoid valve 97 is sealed to the inlet interface 7 via a second pipeline 98, thereby achieving communication with the inlet air passage 51b inside the sealing ring 5. The second selection end of the second three-way solenoid valve 97 is connected to a regeneration exhaust pipe 99, which passes through the housing 91 and extends outward, with its end connected to the outside atmosphere.

[0055] Understandably, through the coordinated switching of the first three-way solenoid valve 94 and the second three-way solenoid valve 97, the dehumidification circulation device 9 can switch between two working states: In the dehumidification circulation state, the common end of the first three-way solenoid valve 94 is connected to the first pipeline 95, and the common end of the second three-way solenoid valve 97 is connected to the second pipeline 98. The circulation pump 92 drives the gas in the interlayer space 4 along the path: "interlayer space 4 → exhaust port 55 → exhaust channel 51a → exhaust port 6 → first pipeline 95 → first three-way solenoid valve 94 → circulation pump 92 → drying tank 93 → second pipeline 98". The gas circulates through the path of "three-way solenoid valve 97 → second pipeline 98 → air inlet 7 → air inlet channel 51b → air inlet 56 → interlayer space 4". When the gas flows through the drying tank 93, the moisture in it is adsorbed, thus achieving dehumidification. In the regeneration exhaust state, the common end of the first three-way solenoid valve 94 is connected to the regeneration air inlet pipe 96, and the common end of the second three-way solenoid valve 97 is connected to the regeneration exhaust pipe 99. Outside air enters the circulation pump 92 through the regeneration air inlet pipe 96, is sent into the drying tank 93, and is discharged to the outside atmosphere through the regeneration exhaust pipe 99 after carrying the water vapor desorbed by the desiccant.

[0056] It should be noted that when switching between dehumidification circulation mode and regeneration exhaust mode, the interlayer space 4 remains isolated from the outside atmosphere due to the synchronous operation of the two three-way solenoid valves. In dehumidification circulation mode, both the regeneration intake pipe 96 and the regeneration exhaust pipe 99 are closed by the three-way solenoid valves, preventing outside air from entering. In regeneration exhaust mode, the first pipe 95 and the second pipe 98 are closed by the first three-way solenoid valve 94 and the second three-way solenoid valve 97, respectively, preventing gas leakage from the interlayer space 4. This isolation mechanism with synchronous switching of dual valves ensures that outside moisture does not seep back into the interlayer space 4 during the regeneration process.

[0057] Please see Figure 10In an optional embodiment of this application, a heating pipe 910 is arranged around the outer periphery of the drying tank 93. The heating pipe 910 is connected to a heating module 911, wherein the heating module 911 is electrically connected to the power module 16 via a wire. The heating pipe 910 is used to heat the drying tank 93, wherein the drying tank 93 is filled with a renewable solid desiccant.

[0058] Specifically, heating pipes 910 are arranged around the outer peripheral wall of the drying tank 93. These heating pipes 910 are spiral or serpentine around the outer surface of the drying tank 93 to uniformly heat the drying tank 93. The heating pipes 910 can be resistance heating tubes, heating wires, or PTC heating elements, and are connected to the heating module 911, which controls their heating power and heating time. The heating module 911 is electrically connected to the power module 16 via wires, and is powered by the power module 16. The interior of the drying tank 93 is filled with a renewable solid desiccant, such as 3A molecular sieve, 4A molecular sieve, activated alumina, or silica gel. When heated to a certain temperature, these desiccants can desorb and release the adsorbed moisture, restoring their adsorption capacity. Understandably, when the desiccant in the drying tank 93 becomes saturated due to long-term use, the drying tank 93 is heated through the heating pipe 910, causing the adsorbed moisture in the desiccant to desorb. Simultaneously, by switching between the first three-way solenoid valve 94 and the second three-way solenoid valve 97, outside air is introduced to carry away and discharge the desorbed moisture, thus completing the online regeneration of the desiccant. This peripheral heating structure avoids direct contact between the heating element and the desiccant, making desiccant replacement and maintenance more convenient. It also ensures more uniform heating, avoiding the risk of localized overheating leading to desiccant failure.

[0059] Please refer to the following: Figure 3 , Figure 4 and Figure 6 In an optional embodiment of this application, the sealing ring 5 has a sensor mounting groove on the inner wall facing the interlayer space 4. A temperature and humidity sensor 15 is embedded and fixed in the sensor mounting groove. The detection probe 151 of the temperature and humidity sensor 15 extends into the interlayer space 4, and the detection probe 151 is arranged near the inner surface of the outer glass 3.

[0060] Specifically, a sensor mounting groove is formed on the inner wall of the sealing ring 5 facing the interlayer space 4. The opening of the sensor mounting groove faces the interlayer space 4, and its shape is adapted to the shape of the temperature and humidity sensor 15. The temperature and humidity sensor 15 is embedded and fixed in the sensor mounting groove, and an airtight seal is achieved between it and the groove wall by sealant or sealing ring to prevent gas leakage from the interlayer space 4. The detection probe 151 of the temperature and humidity sensor 15 extends from the groove opening and into the interior of the interlayer space 4. The detection probe 151 is positioned close to the inner surface of the outer glass 3, that is, the distance between the detection probe 151 and the inner surface of the outer glass 3 is less than the distance between it and the inner surface of the inner glass 2. It can be understood that the inner surface of the outer glass 3 is the area with the lowest temperature in the interlayer space 4, and it is also the location where condensation first occurs. By positioning the detection probe 151 of the temperature and humidity sensor 15 close to the inner surface of the outer glass 3, the air state parameters (temperature and relative humidity) closest to the condensation risk point can be detected, thereby improving the accuracy and timeliness of condensation risk assessment.

[0061] Please refer to the following: Figure 1 and Figure 7 In an optional embodiment of this application, a controller 17 is provided on the outer wall of the frame 1. The controller 17 is electrically connected to the temperature and humidity sensor 15, the micro air pump 10, the circulation pump 92, the first three-way solenoid valve 94, the second three-way solenoid valve 97, the heating module 911, and the power module 16. The power module 16 is used to supply power to the temperature and humidity sensor 15, the micro air pump 10, the circulation pump 92, the first three-way solenoid valve 94, and the second three-way solenoid valve 97. The controller 17 has a built-in dew point calculation program and a preset temperature difference threshold. The controller 17 calculates the dew point temperature Td based on the temperature T and relative humidity RH inside the interlayer space 4 detected by the temperature and humidity sensor 15. When T - Td ≤ the first preset temperature difference threshold, the controller 17 controls the power module 16 to supply power to the heating layer 142 and controls the circulation pump 92 to start the dehumidification cycle until T - Td ≥ the second preset temperature difference threshold.

[0062] Specifically, a controller 17 is fixedly mounted on the outer wall of the frame 1. This controller 17 is a programmable logic controller (PLC) or microcomputer controller, comprising a microprocessor, a signal acquisition module, a drive module, and a storage module. The controller 17 is electrically connected to the temperature and humidity sensor 15, the miniature air pump 10, the circulation pump 92, the first three-way solenoid valve 94, the second three-way solenoid valve 97, the heating module 911, and the power module 16 via wires. The power module 16 provides operating power to the temperature and humidity sensor 15, the miniature air pump 10, the circulation pump 92, the first three-way solenoid valve 94, and the second three-way solenoid valve 97.

[0063] The controller 17 internally stores a dew point temperature calculation program. The controller 17 obtains the temperature T and relative humidity RH inside the interlayer space 4 in real time through the temperature and humidity sensor 15, and calculates the dew point temperature Td according to the following formula: in, , .

[0064] The controller 17 also stores a first preset temperature difference threshold and a second preset temperature difference threshold. For example, the first preset temperature difference threshold can be 3℃, and the second preset temperature difference threshold can be 8℃. The controller 17 calculates the temperature difference ΔT = T - Td in real time. When ΔT ≤ the first preset temperature difference threshold, the controller 17 determines that there is a risk of condensation in the interlayer space 4, and then issues a control command: controlling the power module 16 to supply power to the heating layer 142 (powering the heating element 14 to radiate heat to the interlayer space 4 to increase the glass surface temperature), and simultaneously controlling the circulation pump 92 to start and putting the first three-way solenoid valve 94 and the second three-way solenoid valve 97 into dehumidification circulation mode (the common terminal is connected to the first selection terminal), thus initiating the dehumidification cycle. As the dehumidification cycle proceeds, the relative humidity in the interlayer space 4 gradually decreases, the dew point temperature Td decreases accordingly, and the temperature difference ΔT gradually increases. When ΔT ≥ the second preset temperature difference threshold, the controller 17 determines that the condensation risk has been eliminated. It then controls the power module 16 to stop supplying power to the heating layer 142 and stops the circulation pump 92. Simultaneously, it keeps the first three-way solenoid valve 94 and the second three-way solenoid valve 97 in standby position for dehumidification circulation. It can be understood that by real-time monitoring of the temperature and humidity within the interlayer space 4 and calculating the dew point temperature, the controller 17 can accurately determine whether the interlayer space 4 is in a condensation risk state. When the risk occurs, it promptly initiates heating and dehumidification measures, and automatically stops operation after the risk is eliminated. This ensures the anti-condensation effect while avoiding unnecessary energy consumption. It should be noted that the heating control of the heating layer 142 and the dehumidification circulation control of the circulation pump 92 are started synchronously because when the condensation risk occurs, simply relying on dehumidification circulation to reduce humidity takes time, while heating can instantly raise the glass surface temperature, providing rapid protection before the dehumidification circulation is fully effective. The synergistic effect of both can more effectively prevent condensation formation.

[0065] Please see Figure 1 In an optional embodiment of this application, the controller 17 has a built-in working time statistics program and a regeneration trigger threshold. The controller 17 can accumulate and count the effective working time of the dehumidification circulation device 9. When the accumulated working time reaches the preset regeneration trigger threshold, the controller 17 controls the first three-way solenoid valve 94 and the second three-way solenoid valve 97 to switch to the regeneration pipeline conduction state simultaneously, and controls the heating module 911 to be powered on and put into operation.

[0066] Specifically, the controller 17 also stores a working time statistics program and a regeneration trigger threshold. The working time statistics program is used to accumulate the effective working time of the dehumidification circulation device 9, that is, the cumulative running time of the circulation pump 92 in the dehumidification circulation state (with both the first three-way solenoid valve 94 and the second three-way solenoid valve 97 in the state of being connected to the common terminal and the first select terminal). When the cumulative working time reaches the preset regeneration trigger threshold (e.g., 200 hours), the controller 17 determines that the solid desiccant in the drying tank 93 is close to the adsorption saturation state and needs to be regenerated.

[0067] The controller 17 then issues a regeneration control command: controlling the first three-way solenoid valve 94 to switch its common terminal to the state where it is connected to the second selector terminal (i.e., the first pipeline 95 is closed and the regeneration air inlet pipe 96 is open), and simultaneously controlling the second three-way solenoid valve 97 to switch its common terminal to the state where it is connected to the second selector terminal (i.e., the second pipeline 98 is closed and the regeneration exhaust pipe 99 is open), so that the two three-way solenoid valves are synchronously switched to the state where the regeneration pipeline is open. At the same time, the controller 17 controls the power module 16 to supply power to the heating module 911, and the heating module 911 heats the drying tank 93 through the heating pipe 910, so that the temperature of the solid desiccant in the drying tank 93 rises to the regeneration temperature, and the adsorbed moisture is desorbed by heat. The circulation pump 92 starts at the same time, drawing in outside air from the regeneration air inlet pipe 96. This air flows through the inside of the drying tank 93, carrying the water vapor released by the desorbed desiccant and expelling it to the outside atmosphere from the regeneration exhaust pipe 99.

[0068] After the regeneration process continues for a preset time (e.g., 30 minutes), the controller 17 stops the power supply to the heating module 911 and the operation of the circulation pump 92, switches the first three-way solenoid valve 94 and the second three-way solenoid valve 97 back to the dehumidification circulation state, and resets the accumulated working time to zero, restarting the timing. It can be understood that by accumulating the effective working time and automatically triggering the regeneration program based on this, fully automated management of desiccant regeneration is achieved without manual intervention, ensuring that the solid desiccant in the drying tank 93 is always maintained within the effective adsorption capacity range. It should be noted that during the regeneration process, because the first three-way solenoid valve 94 closes the first pipeline 95 and the second three-way solenoid valve 97 closes the second pipeline 98, the gas in the interlayer space 4 is completely isolated from the regeneration exhaust gas path. External air and hot air carrying moisture will not enter the interlayer space 4, effectively preventing the reverse infiltration of external moisture.

[0069] While specific embodiments of the present invention have been described above, those skilled in the art should understand that these are merely illustrative examples, and the scope of protection of the present invention is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, but all such changes and modifications fall within the scope of protection of the present invention.
