Energy saving window based on solar energy

Abstract

The solar energy-based energy-saving window curtain provided in the specification is provided with a heat dissipation device between the window curtain device and the window, and the heat dissipation device is powered by a solar energy device; when the window curtain device completely covers the target window, a sealed connection is formed between the window curtain device and the target window, and a cooling device in the heat dissipation device can cool the sealed air between the window curtain device and the window, so as to reduce the temperature of the sealed air. When the temperature sensor senses that the temperature of the sealed air is increased, the control device controls the cooling device to start to reduce the temperature of the sealed air, so that the heat outside the window cannot be conducted to the inside of the window curtain device through the sealed air, thereby improving the energy-saving and emission-reducing effect; at the same time, the power of the heat dissipation device comes from renewable solar energy, which can further reduce carbon emissions.

Description

Technical Field

[0001] This manual relates to the field of building energy conservation, and in particular to an energy-saving window curtain based on solar energy. Background Technology

[0002] In building structures, transparent parts (such as windows) are a crucial component, representing the most active and sensitive areas for heat exchange and conduction. Energy loss through these transparent parts primarily occurs through heat conduction, convection, and radiation. Heat exchange through windows is 5-6 times greater than that through walls. Statistics show that energy consumption through transparent parts accounts for over 50% of a building's total energy consumption. Therefore, research into energy-saving measures for transparent building components is receiving increasing attention. While existing sealed window curtains can eliminate gaps between the curtain and the wall, preventing heat from entering the room through these gaps, they cannot completely prevent heat from entering the room through windows and curtains via heat exchange and conduction, thus impacting the building's energy consumption.

[0003] Therefore, there is a need for a solar-powered energy-saving window curtain that can eliminate the gap between the window curtain and the wall, and at the same time prevent heat from entering the room through the window and window curtain by heat exchange and heat conduction without increasing carbon emissions, thereby improving energy conservation and emission reduction. Summary of the Invention

[0004] This manual provides a solar-powered energy-saving window curtain that eliminates the gap between the window curtain and the wall, while preventing heat from entering the room through the window and window curtain via heat exchange and heat conduction without increasing carbon emissions, thereby improving energy conservation and emission reduction.

[0005] This specification provides a solar-powered energy-saving window curtain for installation on a target window. It includes a window curtain assembly and a heat dissipation device. The window curtain assembly is installed on one side of the window, connected to a fixed surface around the target window, and is movable to change the area covered by the window. When the window curtain assembly completely obscures the target window, a sealed connection is formed between the assembly and the fixed surface, and a sealed cavity is formed between the assembly and the window. The heat dissipation device is installed on the window curtain assembly, located between the window and the assembly, and includes a housing, a cooling device, and a solar energy device. The housing is installed on the window curtain assembly. The cooling device is installed on the housing and, during operation, cools the sealed air between the window and the assembly to reduce its temperature. The solar energy device is installed on the window curtain assembly and electrically connected to the cooling device, converting solar energy into electrical energy to power the cooling device.

[0006] In some embodiments, the heat dissipation device further includes a control device mounted on the housing, which is communicatively connected to the cooling device during operation to control the start and stop of the cooling device.

[0007] In some embodiments, the heat dissipation device further includes at least one position sensor installed on the window curtain device, which communicates with the control device during operation to detect the position of the window curtain device and send the position data to the control device to determine whether the window curtain device completely blocks the target window. When the window curtain device completely blocks the target window, the control device controls the cooling device to start.

[0008] In some embodiments, the heat dissipation device further includes at least one temperature sensor mounted on the housing, which is communicatively connected to the control device during operation to monitor the temperature data of the sealed air and send the temperature data to the control device. When the window curtain device completely blocks the target window and the temperature of the sealed air is higher than a set temperature threshold, the control device controls the cooling device to start.

[0009] In some embodiments, when the curtain device completely obscures the target window and the current time is within a preset time range, the control device controls the cooling device to start.

[0010] In some embodiments, the cooling device includes a thermoelectric cooler and a fan. The thermoelectric cooler is mounted on the housing and electrically connected to the solar energy device. It includes a cooling end and a heating end. During operation, it transfers heat from the cooling end to the heating end, thereby lowering the temperature of the cooling end. The fan is mounted on the housing and, during operation, delivers the low-temperature air from the cooling end into the sealed cavity between the window and the curtain wall device to cool the sealed air.

[0011] In some embodiments, the air inlet of the fan faces the cooling end, and the air outlet of the fan faces the enclosed air.

[0012] In some embodiments, the fan includes an air inlet facing indoors or outdoors; a first air outlet facing the cooling end and the sealed cavity to cool the sealed cavity; a second air outlet facing the heating end and the sealed cavity to heat the sealed cavity; and a damper assembly configured to control the opening and closing of the first air outlet and the second air outlet.

[0013] In some embodiments, the damper assembly includes a damper and a drive motor, the damper being movably disposed at the first air outlet and the second air outlet; the drive motor is configured to control the damper to move between a first position and a second position, wherein when the damper is in the first position, the damper blocks the first air outlet and opens the second air outlet; and when the damper is in the second position, the damper blocks the second air outlet and opens the first air outlet.

[0014] In some embodiments, the damper includes: a first damper movably disposed at the first air outlet; and a second damper movably disposed at the second air outlet. The drive motor includes: a first drive motor configured to control the opening and closing of the first damper; and a second drive motor configured to control the opening and closing of the second damper.

[0015] In some embodiments, the cooling end is provided with heat-conducting fins.

[0016] In some embodiments, the heat dissipation device further includes a power supply device mounted on the housing and electrically connected to the cooling device and the solar energy device, respectively, to absorb electrical energy from the solar energy device and supply power to the cooling device.

[0017] In some embodiments, the heat dissipation device further includes a thermal power generation device, which is mounted on the housing and electrically connected to the power supply device, and is configured to absorb heat from the heating end and convert the heat into electrical energy to charge the power supply device.

[0018] In some embodiments, the thermal power generation device includes a thermal storage device and a thermoelectric generator. The thermal storage device is connected to the heating end and absorbs and stores the heat from the heating end during operation. The first end of the thermoelectric generator is connected to the thermal storage device, and the second end is electrically connected to the power supply device. When the heat stored in the thermal storage device reaches a preset value, the thermal storage device releases heat to the first end, causing the temperature of the first end to rise. The thermoelectric generator generates electrical energy based on the temperature difference between the first end and the second end to charge the power supply device.

[0019] In some embodiments, the heat storage device includes a heat storage unit comprising a phase change material, wherein during operation, the phase change material absorbs heat from the heating end, thereby undergoing a phase change and storing the heat.

[0020] In some embodiments, the window curtain device includes a fixed frame, a movable frame, and the curtain. The fixed frame is connected to a fixed surface around the target window during use. The movable frame is disposed opposite to the fixed frame and can be opened and closed relative to the fixed frame. The curtain is located between the fixed frame and the movable frame and can move between a first position and a second position to change the area covered on the target window. When the curtain is in the second position, it completely covers the target window. When the curtain is in the second position, the movable frame closes with the fixed frame and clamps the curtain, thereby forming a sealed connection between the curtain and the fixed surface of the target window.

[0021] In some embodiments, the solar energy device includes a solar panel made of a flexible material and attached to the outdoor-facing surface of the curtain.

[0022] In some embodiments, the heat dissipation device includes a housing, a fan disposed within the housing, the housing including a fresh air inlet configured to communicate with the outside; a fresh air outlet configured to communicate with the inside; a vent configured to communicate with the sealed cavity; and a fresh air damper configured to open and close the fresh air outlet; the fan inlet is connected to the fresh air inlet, and the fan outlet is connected to both the fresh air outlet and the vent.

[0023] In some embodiments, the fresh air damper is disposed between the fresh air outlet and the vent. The fresh air damper is configured to move between a fresh air open position and a fresh air closed position. When the fresh air damper is in the fresh air open position, the fresh air damper opens the fresh air outlet and closes the vent. When the fresh air damper is in the fresh air closed position, the fresh air damper closes the fresh air outlet and opens the vent.

[0024] In some embodiments, an air filtration module is provided at the fresh air inlet and / or the fresh air outlet.

[0025] In some embodiments, the air filtration module includes one or more of the following: a photocatalyst layer, an activated carbon layer, and a sponge layer, which are stacked together.

[0026] As can be seen from the above technical solutions, the solar-powered energy-saving window curtain provided in this specification has a heat dissipation device installed between the window curtain device and the window, and uses a solar energy device to power the heat dissipation device. When the window curtain device completely covers the target window, a sealed connection is formed between the window curtain device and the target window. The cooling device in the heat dissipation device can cool the sealed air between the window curtain device and the window to reduce the temperature of the sealed air. When the temperature sensor detects an increase in the temperature of the sealed air, the control device activates the cooling device to lower the temperature of the sealed air. Although outdoor heat still heats the air inside the sealed cavity through the windows, the cooling device keeps the air in the sealed cavity at the same or similar temperature as the indoor temperature. Therefore, the heat from the outdoor air is pre-cooled by the sealed air before it reaches the sealed cavity, preventing the indoor temperature from rising. This reduces energy consumption in the transparent parts of the building and improves energy conservation and emission reduction. Furthermore, because a solar energy device converts solar energy into electricity to power the cooling device, the power source for the heat dissipation device is renewable solar energy. Compared to heat dissipation devices driven by ordinary electricity, this reduces carbon emissions and further enhances energy conservation and emission reduction.

[0030] The following description provides specific application scenarios and requirements for this specification, intended to enable those skilled in the art to make and use the contents of this specification. Various partial modifications to the disclosed embodiments will be apparent to those skilled in the art, and the general principles defined herein can be applied to other embodiments and applications without departing from the spirit and scope of this specification. Therefore, this specification is not limited to the embodiments shown, but rather to the widest scope consistent with the claims.

[0031] The terminology used herein is for the purpose of describing particular exemplary embodiments only and is not restrictive. For example, unless the context clearly indicates otherwise, the singular forms “a,” “an,” and “the” used herein may also include the plural forms. When used in this specification, the terms “comprising,” “including,” and / or “containing” mean that the associated integers, steps, operations, elements, and / or components are present, but do not exclude the presence of one or more other features, integers, steps, operations, elements, components, and / or groups, or that other features, integers, steps, operations, elements, components, and / or groups may be added to the system / method.

[0032] Considering the following description, these and other features of this specification, as well as the operation and function of the related components of the structure, and the economy of assembly and manufacture of the parts, can be significantly improved. All of these form part of this specification with reference to the accompanying drawings. However, it should be clearly understood that the drawings are for illustrative and descriptive purposes only and are not intended to limit the scope of this specification. It should also be understood that the drawings are not drawn to scale.

[0033] This manual provides a solar-powered energy-saving window curtain 001. Figure 1 A side view of a solar-powered energy-saving window curtain 001 provided according to an embodiment of this specification is shown. For ease of description, we can define the Z direction as top, the opposite direction of the Z direction as bottom, the Y direction as front, the opposite direction of the Y direction as back, the X direction as left, and the opposite direction of the X direction as right.

[0034] The solar-powered energy-saving window curtain 001 can be attached to a target window 003 on a building or other man-made structure to block the light channel formed by the target window 003. For example, the solar-powered energy-saving window curtain 001 can be installed on a fixed surface around the target window. The building can be any type of building, such as an office building, residential building, self-built house, multi-story building, etc. In some embodiments, the other man-made structure can be a vehicle, such as a car, public transportation vehicle, such as a train, bus, etc., or even an airplane. The target window 003 can be an opening or light channel on the building or other man-made structure to allow light or air to enter a space (such as an interior or vehicle interior). In some embodiments, a glass window 002 can be installed on the target window 003. The window 002 can divide the space into indoor and outdoor parts. When the window 002 is closed, the indoor and outdoor parts are separated by the window 002, and air cannot circulate. For ease of description, we define the Y direction as the indoor side and the opposite direction of the Y direction as the outdoor side. The target window 003 can be an opening or light channel of any shape, such as a rectangle, a circle, a rounded rectangle, a semicircle, etc. For ease of description, we will use a rectangle as an example. The target window 003 may include a fixed surface 004 and a window opening surrounded by the fixed surface 004. The window opening is the channel through which light passes. The fixed surface 004 may include four mounting surfaces surrounding the target window 003, which together constitute the target window 003.

[0035] like Figure 1As shown, the solar-powered energy-saving window curtain 001 may include a window curtain device 1000 and a heat dissipation device 2000. The window curtain device 1000 can be installed on one side of a window 002 during use. In some embodiments, the window curtain device 1000 can be installed on the side of the window 002 facing inwards. In some embodiments, the window curtain device 1000 can be installed on the side of the window 002 facing outwards. For ease of illustration, the following description will use the example of the window curtain device 1000 being installed on the side of the window 002 facing inwards. During installation, the window curtain device 1000 can be connected to a fixed surface 004 around the target window 003. During use, the window curtain device 1000 can be moved to change the area covered on the target window 003. When the window curtain device 1000 completely blocks the target window 003, the window curtain device 1000 can form a sealed connection with the fixed surface 004, eliminating the gap between the window curtain device 1000 and the target window 003. This prevents air from circulating between the two sides of the window curtain device 1000 inside the target window 003, either through the gap between the window curtain device 1000 and the target window 003 or through the window curtain device 1000 itself. This isolates the air circulation between the two sides of the window curtain device 1000 inside the target window 003, reducing heat transfer caused by air circulation, improving energy efficiency, and blocking mosquitoes, dust, and other impurities.

[0036] The heat dissipation device 2000 can be installed on the window curtain device 1000 and located between the window 002 and the window curtain device 1000. As mentioned above, when the window curtain device 1000 completely blocks the target window 003, the window curtain device 1000 can form a sealed connection with the fixed surface 004. At this time, a sealed cavity is formed between the window 002 and the window curtain device 1000. In order to prevent heat from the outside from being transferred to the room through the window 002, the sealed air in the sealed cavity, and the window curtain device 1000 via heat conduction, the heat dissipation device 2000 can cool the sealed air in the sealed cavity to reduce the temperature of the sealed air and prevent heat from the window 002 from being transferred to the window curtain device 1000 and the room through the sealed air.

[0037] Figure 2 A schematic diagram of an oblique structure of a window curtain device 1000 provided according to an embodiment of this specification is shown; Figure 3 An exploded structural diagram of a window curtain device 1000 provided according to an embodiment of this specification is shown. Figures 2 to 3 As shown, the window curtain device 1000 may include a fixed frame 200, a movable frame 400, and a curtain 600. In some embodiments, the window curtain device 1000 may also include a connecting mechanism 800. In some embodiments, the window curtain device 1000 may also include a transmission mechanism 900.

[0038] A window curtain device 1000 can be installed on a target window 003 (for example, the window curtain device 1000 can be installed on a fixed surface around the target window) to partially or completely block the target window 003. When the window curtain device 1000 is in a first position, the window curtain device 1000 is fully open, allowing light to pass through the target window 003; when the window curtain device 1000 is in a second position, the window curtain device 1000 is fully closed, completely blocking the target window 003. The position of the window curtain device 1000 can be moved between the first position and the second position to change the coverage area or blocking area of ​​the target window 003. For ease of description, we define the direction formed by the first position and the second position as the target direction. That is, the target direction can be the direction from the first position to the second position or the direction from the second position to the first position. In some embodiments, the target direction can be the direction of the Z-axis, i.e., the up-down direction. In some embodiments, the target direction can be the direction of the X-axis, i.e., the left-right direction. For ease of demonstration, we will describe the target direction as the direction of the Z-axis, that is, the first position and the second position can be above and below the target window 003, respectively.

[0039] like Figures 2 to 3 As shown, the fixed frame 200 can be fixedly connected to the fixed surface 004 around the window opening during use. The outer edge of the fixed frame 200 can match the shape and size of the target window 003. For example, if the target window 003 is rectangular, the fixed frame 200 can also be rectangular. In some embodiments, the fixed frame 200 and the fixed surface 004 can be sealed with a sealing material, such as rubber, sealant, foam, etc.

[0040] In some embodiments, the fixed frame 200 may further include a first magnetic body 280, such as a first magnetic strip. The first magnetic body 280 may be a magnetic device capable of generating an attractive force. In this specification, the first magnetic body 280 may be disposed on the Y-direction-oriented side (i.e., the front side) of the fixed frame 200.

[0041] like Figures 2 to 3As shown, the movable frame 400 can be positioned opposite the fixed frame 200 during operation and is movably connected to the fixed frame 200 to open and close parallel to the fixed frame 200. The movable frame 400 can be movably connected to the fixed frame 200 in any manner, allowing the movable frame 400 to translate relative to the fixed frame 200, thereby changing the distance between the movable frame 400 and the fixed frame 200, and causing the movable frame 400 to move closer to or away from the fixed frame 200. When the movable frame 400 approaches and contacts the fixed frame 200, a seal can be formed between the movable frame 400 and the fixed frame 200. When the movable frame 400 moves away from the fixed frame 200 and opens, a gap may exist between the movable frame 400 and the fixed frame 200.

[0042] In some embodiments, the movable frame 400 may further include a second magnet 480. The second magnet 480 may be a magnetic device capable of generating an attractive force with the first magnet 280. The second magnet 480 may be disposed opposite to the first magnet 280. When the curtain wall device 1000 is in the second position, the movable frame 400 approaches the fixed frame 200 under the attractive force of the first magnet 280 and the second magnet 480, and closes relative to the fixed frame 200. In this specification, the second magnet 480 may be disposed on the side of the movable frame 400 opposite to the Y-direction (i.e., the reverse side).

[0043] like Figures 2 to 3 As shown, the curtain wall device 1000 may further include a connecting mechanism 800. The connecting mechanism 800 can be connected to the fixed frame 200 and the movable frame 400. The movable frame 400 can be indirectly connected to the fixed frame 200 through the connecting mechanism 800, and the movable frame 400 and the fixed frame 200 achieve the aforementioned movable connection under the action of the connecting mechanism 800.

[0044] In some embodiments, the connecting mechanism can be a four-bar linkage, in which case the connecting mechanism 800 may include at least two connecting rods 820 distributed at different positions. The two ends of each connecting rod 820 are hinged to the fixed frame 200 and the movable frame 400 respectively, thereby forming a four-bar linkage, allowing the movable frame 400 to open and close parallel to the fixed frame 200. Figures 2 to 3 As shown, three connecting rods 820 are illustrated. Those skilled in the art will understand that two or more connecting rods 820 are within the scope of this specification. In some embodiments, the connecting mechanism 800 may also be a linkage slider mechanism, a slider guide mechanism, etc.

[0045] like Figures 2 to 3As shown, the curtain 600 can be located between the fixed frame 200 and the movable frame 400, and can move between the first position and the second position to change the area covered on the target window 003. When the curtain 600 is in the second position, it completely blocks the target window 003. When the curtain 600 is in the second position, the movable frame 400 approaches the fixed frame 200 and closes relative to the fixed frame 200 to clamp the curtain 600, thereby forming a sealed connection between the curtain 600 and the fixed surface 004 of the target window 003. This prevents air from circulating between the two sides of the curtain 600 inside the target window 003 through the gap between the curtain 600 and the target window 003, and also prevents sunlight from passing through the window curtain device 1000 through the gap between the curtain 600 and the target window 003, thus reducing heat transfer caused by air circulation, improving energy efficiency, and blocking mosquitoes, dust, and other impurities.

[0046] The curtain 600 can be made of any light-blocking material, and can be opaque, transparent, or semi-transparent light-guiding material. The light blocking can block part or all of the light rays to prevent them from passing through the curtain 600. The light blocking can be a preset proportion of light wavelengths being blocked, such as reflecting ultraviolet rays, infrared rays, and some visible light. In this application, the curtain 600 is exemplified as a transparent light-guiding curtain. In some embodiments, the light-guiding curtain can be completely transparent or made of a partially reflective and partially permeable medium. For example, the light-guiding curtain can reflect a preset proportion of light wavelengths, such as reflecting ultraviolet rays, infrared rays, and some visible light. In some embodiments, the light-guiding curtain can include at least one transparent base film and at least one partially reflective film. The partially reflective film can be attached to the transparent base film to reflect a portion of the light wavelengths. The light-guiding curtain can allow a preset proportion of visible light to pass through, such as allowing 0-0.1%, 1%, 2%, 5%, 7%, 8%, 10% of visible light to pass through, etc. For example, the partially reflective film can be a metal coating of a predetermined thickness, such as an aluminum coating. The material and thickness of the partially reflective film can be changed according to usage requirements to alter the light transmittance of the light guide curtain. A transparent base film can enhance the view-through effect of the light guide curtain. In this way, users can see the scenery outside the window without obstruction through the light guide curtain, and can also utilize the light guide curtain to reflect a preset proportion of light, preventing the indoor temperature from being excessively heated by the light, thus achieving energy-saving effects.

[0047] In some embodiments, the light guide curtain may include multiple layers of partially reflective films. For example, the first layer of partially reflective film may be a transparent polyester layer to block ultraviolet rays, the second layer of partially reflective film may be a polyester metallic coating to reflect solar heat, and the third layer of partially reflective film may be a polyester film layer to allow visible light to pass through.

[0048] In some embodiments, the curtain 600 may be made of an airtight material, such as a non-porous material. When the curtain 600 is in the second position, the movable frame 400 closes relative to the fixed frame 200 to clamp the curtain 600, thereby forming a sealed connection between the curtain 600 and the fixed surface 004 of the target window 003. This prevents air from circulating between the two sides of the curtain 600 inside the target window 003, either through the gap between the curtain 600 and the target window 003 or through the curtain 600 itself, thus isolating airflow between the two sides of the curtain 600 inside the target window 003. Simultaneously, light cannot pass through the gap between the curtain 600 and the target window 003 through the window curtain device 1000, reducing heat transfer caused by airflow, improving energy efficiency, and blocking insects, dust, and other impurities.

[0049] In some embodiments, the window curtain device 1000 further includes a transmission mechanism 900. The transmission mechanism 900 can be directly or indirectly mounted on the fixed surface 004. The transmission mechanism 900 can be connected to the curtain 600, and during operation, under the action of an external force, drives the curtain 600 to move between the first position and the second position, changing the area of ​​the curtain 600 obstructing the target window 003. The external force can be manual or electric, such as a drive motor.

[0050] In some embodiments, the curtain wall device 1000 can also be any form of sealable curtain wall structure, such as a magnetic strip seal curtain wall, a Velcro seal curtain wall, a bayonet seal curtain wall, a lockable push-pull seal curtain wall, a sealable curtain wall with a manual sealing structure, etc. Those skilled in the art should understand that any form of curtain wall device 1000 that can achieve a sealed connection between the curtain wall device 1000 and the fixed surface 004 of the target window 003 is within the scope of protection of this specification.

[0051] Figure 4 A front view of a heat dissipation device 2000 provided according to an embodiment of this specification is shown. Figure 4 The heat dissipation device 2000 shown is viewed from the outdoor side towards the indoor side. For example... Figure 4 As shown, the heat dissipation device 2000 may include a housing 2100, a cooling device 2200, and a solar energy device 2800. In some embodiments, the heat dissipation device 2000 may further include a power supply device 2300. In some embodiments, the heat dissipation device 2000 may further include a control device 2400. In some embodiments, the heat dissipation device 2000 may further include at least one position sensor 2500. In some embodiments, the heat dissipation device 2000 may further include at least one temperature sensor 2600. In some embodiments, the heat dissipation device 2000 may further include a thermal power generation device 2900.

[0052] The housing 2100 can be the mounting base for the heat dissipation device 2000. The housing 2100 can be mounted on the curtain wall device 1000 and fixedly connected to it. In some embodiments, the housing 2100 can be mounted on the fixed frame 200 of the curtain wall device 1000. In some embodiments, the housing 2100 can be mounted on the outer casing (top box of the curtain wall device 1000) where the transmission mechanism 900 of the curtain wall device 1000 is located. In some embodiments, the outer casing where the transmission mechanism 900 of the curtain wall device 1000 is located can be used as the housing 2100. That is, the heat dissipation device 2000 and the curtain wall device 1000 can share the same housing 2100. In some embodiments, the housing 2100 can be mounted at any position on the curtain wall device 1000, such as the upper side, lower side, left side, right side, etc. For ease of description, in... Figure 1 and Figure 4 In the diagram shown, the housing 2100 is located on the upper side of the curtain wall device 1000. Those skilled in the art will understand that other locations where the housing 21000 is installed on the curtain wall device 1000 are also within the scope of this specification. In some embodiments, the housing 2100 can be detachably and fixedly installed with the curtain wall device 1000, for example, by threaded connection, bayonet connection, etc. In some embodiments, the housing 2100 can be fixedly connected to the curtain wall device 1000, for example, by welding, riveting, bonding, etc. In some embodiments, the housing 2100 can be integrally formed with the curtain wall device 1000. In some embodiments, the housing 2100 can include a single unit. In some embodiments, the housing 2100 can include multiple independent sub-housings. The multiple independent sub-housings can be installed at any location on the curtain wall device 1000. For example, the number of independent sub-housings can be two, installed on the upper and lower sides of the curtain wall device 1000 respectively. Alternatively, the number of independent sub-housings can be four, installed on the upper, lower, left, and right sides of the curtain wall device 1000 respectively. For ease of description, we will use the example of housing 2100 comprising two independent sub-housings, which are respectively installed on the upper and lower sides of the curtain wall device 1000. The upper sub-housing can be connected to the housing (top box of the curtain wall device 1000) where the transmission mechanism 900 is located. The lower sub-housing can be connected to the bottom frame of the fixed frame 200.

[0053] The cooling device 2200 can be installed on the housing 2100. In some embodiments, the cooling device 2200 can be installed on the exterior of the housing 2100, for example, on one side of the housing 2100, such as the upper, lower, left, or right side. In some embodiments, the cooling device 2200 can be installed inside the housing 2100. For ease of illustration, we will describe the cooling device 2200 as installed on the upper housing. Those skilled in the art should understand that the cooling device 2200 can also be installed in other locations on the housing 2100 within the scope of this specification. When the cooling device 2200 is in operation, it can cool the sealed air between the window 002 and the curtain wall device 1000 to reduce the temperature of the sealed air. The cooling device 2200 can be directly or indirectly electrically connected to the solar energy device 2800 (e.g., indirectly connected via the power supply device 2300) to obtain electrical energy from the solar energy device 2800 to provide the necessary energy for the operation of the cooling device 2200. Figure 4 As shown, the cooling device 2200 may include a semiconductor cooler 2210 and a fan 2220.

[0054] The semiconductor cooler 2210 can be mounted on the housing 2100. In some embodiments, the semiconductor cooler 2210 can be mounted on the outside of the housing 2100, for example, on one side of the housing 2100, such as the upper side, lower side, left side, right side, etc. In some embodiments, the semiconductor cooler 2210 can be mounted inside the housing 2100. When operating, the semiconductor cooler 2210 can be directly or indirectly electrically connected to the solar energy device 2800 (e.g., indirectly connected via a power supply device 2300) to obtain electrical energy from the solar energy device 2800. The semiconductor cooler 2210 is a cooling device composed of semiconductors. The semiconductor cooler 2210 includes a cooling end 2211 and a heating end 2212. Its working principle is as follows: after the power is turned on, electrons start from the negative electrode (-), first passing through the P-type semiconductor (cooling end 2211), where they absorb heat. Upon reaching the N-type semiconductor (heating end 2212), they release heat. Each time an electron passes through an NP module, heat is transferred from the cooling end 2211 at one end to the heating end 2212 at the other, causing the temperature of the cooling end 2211 to drop and creating a temperature difference. The cooling end 2211 and the heating end 2212 are each composed of two ceramic plates.

[0055] The fan 2220 can be mounted on the housing 2100. Specifically, the air inlet of the fan 2220 can face the cooling end 2211. The air outlet of the fan 2220 can face the sealed air. When the fan 2220 is working, it can send the low-temperature air from the cooling end 2211 into the sealed cavity between the window 002 and the window curtain device 1000 to cool the sealed air.

[0056] like Figure 5 As shown, the air inlet of fan 2220 can also face indoors or outdoors, and the air outlet of fan 2220 faces the sealed air and the cooling end 2211. When fan 2220 is working, it can also send the low-temperature air from cooling end 2211 into the sealed cavity between window 002 and window curtain device 1000 to cool the sealed air.

[0057] The above structure can be used in hotter weather to reduce the transfer of heat from outdoor hot air into the room. Additionally, in colder weather, to reduce heat loss from indoors through window 002 and curtain 600, the window curtain device 1000 can be structurally designed as follows: like Figure 5 , Figure 6 As shown, the fan 2220 includes an air inlet 2221, a first air outlet 2222, a second air outlet 2223, and a damper assembly. The first air outlet 2222 faces the cooling end 2211 and the sealed cavity to deliver low-temperature air from the cooling end 2211 into the sealed cavity between the window 002 and the curtain device 1000, cooling the sealed air and preventing heat transfer from the outside to the inside during hot weather. Conversely, the second air outlet 2223 faces the heating end 2212 and the sealed cavity to deliver high-temperature air from the heating end 2212 into the sealed cavity between the window 002 and the curtain device 1000, heating the sealed air and reducing heat loss from the inside to the outside through the window and curtain 600 during cold weather. Furthermore, since a damper assembly is provided at the air outlet of the fan 2220, and the damper assembly can control the opening and closing of the first air outlet 2222 and the second air outlet 2223, the cooling or heating function of the window curtain device 1000 can be selected according to different needs, making the window curtain device 1000 more versatile.

[0058] In one possible implementation of the damper assembly, the damper assembly may include a damper and a drive motor. The damper is movably disposed at the first air outlet 2222 and the second air outlet 2223. The drive motor is configured to control the damper to move between a first position and a second position. When the damper is in the first position, the damper blocks the first air outlet 2222, allowing the second air outlet 2223 to open. When the damper is in the second position, the damper blocks the second air outlet 2223, allowing the first air outlet 2222 to open. Thus, the switching between cooling and heating functions of the window curtain device 1000 can be achieved using only one damper, resulting in a simple structure and small footprint.

[0059] For example, the damper assembly can also use two dampers to control the opening and closing of the first air outlet 2222 and the second air outlet 2223 respectively. Figure 5 , Figure 6 As shown, the damper assembly includes a first damper 2224, a second damper 2225, a first drive motor, and a second drive motor (not shown in the figure). The first damper 2224 is movably disposed at the first air outlet 2222, and the first drive motor is used to drive the first damper 2224 to open and close. Figure 5 As shown, when the first damper 2224 is opened, the first air outlet 2222 faces the cooling end 2211 and the sealed cavity, so as to send the low-temperature air from the cooling end 2211 into the sealed cavity to cool the sealed air. The second damper 2225 is movably disposed at the second air outlet 2223, and the second drive motor is used to control the opening and closing of the second damper 2225. Figure 6 As shown, when the second damper 2225 is opened, the second air outlet 2223 faces the heating end 2212 and the sealed cavity, so as to send the high-temperature hot air from the heating end 2212 into the sealed cavity to heat the sealed air. Therefore, by using two dampers and two drive motors to independently control the opening and closing of the first damper 2224 and the second damper 2225, even if one damper or one drive motor fails, it will not affect the normal operation of the other damper or the other drive motor.

[0060] It should be noted that the movement of the aforementioned damper can be either linear or rotational. When the damper adopts a linear movement scheme, a sliding groove can be provided on the inner wall of the air outlet of the fan 2220, allowing the damper to slide within the groove, and enabling the drive motor to control the damper to slide linearly between a first position and a second position. The drive motor can be a linear motor or a rotary motor combined with a linear transmission mechanism. The linear transmission mechanism can convert the rotational motion of the motor output shaft into linear motion; for example, it can be a rack and pinion mechanism, a lead screw and nut mechanism, etc., which are not limited here.

[0061] When the damper adopts a rotating design, it can be rotatably connected to the air outlet of fan 2220 via a rotating shaft, allowing the drive motor to control the damper to rotate and switch between a first position and a second position. The drive motor can be a rotary motor, or a rotary motor combined with a reduction mechanism. The reduction mechanism reduces the rotational speed of the motor output shaft to prevent damage to the damper in case of excessive speed. The reduction mechanism can specifically employ gear transmission, belt transmission, or chain transmission, etc., and is not limited here.

[0062] like Figure 7As shown, in order to increase the contact area between the air outlet of the fan 2220 and the cooling end 2211, heat-conducting fins 2213 can be provided on the cooling end 2211 of the semiconductor cooler 2210, so that the heat-conducting fins 2213 are heat-transferringly connected to the cooling end 2211. Therefore, when the air outlet of the fan 2220 blows towards the cooling end 2211, it can fully contact the heat-conducting fins 2213 that are being cooled by the cooling end 2211, thereby accelerating the cooling of the air outlet of the fan 2220 and avoiding energy waste, resulting in better cooling performance.

[0063] It should be noted that the aforementioned fan 2220 can be an axial flow fan, a centrifugal fan, a cross flow fan, etc., and is not limited here.

[0064] The number of semiconductor coolers 2210 and fans 2220 can be adjusted according to actual usage requirements and space constraints. This manual does not impose any limitations on this.

[0065] The cooling device 2200 can also be other types of equipment, such as a refrigeration unit, a condenser, etc.

[0066] In addition, the window curtain can also integrate the function of a fresh air system, specifically, such as Figure 10 As shown, the semiconductor cooler 2210 and fan 2220 of the cooling device are installed inside the housing 2100. A fresh air inlet (not shown), a fresh air outlet 2102, a vent 2103, and a fresh air damper 2104 can be provided on the housing 2100. The fresh air inlet is connected to the outside; the fresh air outlet 2102 is connected to the inside; the vent 2103 is connected to the sealed cavity; and the fresh air damper 2104 is used to open and close the fresh air outlet 2102. The air inlet 2221 of the fan 2220 is connected to the fresh air inlet. The air outlets of the fan 2220 (first air outlet 2222 and second air outlet 2223) are connected to the fresh air outlet 2102 and the vent 2103. Therefore, when the fresh air function needs to be turned on, the fresh air damper 2104 can be controlled to open the fresh air outlet 2102, so that the air outlet of the fan 2220 is connected to the room. Thus, after the fan 2220 is turned on, fresh air from the outside can be introduced into the room to improve the indoor air quality.

[0067] When using the fresh air function, if the outdoor temperature is too high or too low to be directly introduced into the room, the opening and closing of the first damper 2224 and the second damper 2225 can be controlled to select whether the cold or hot end of the semiconductor cooler 2210 is used to cool or heat the fresh air, so that the fresh air reaches a suitable temperature before entering the room. If the outdoor temperature is suitable, outdoor fresh air can be directly introduced into the room. The power to the semiconductor cooler 2210 can be turned off, preventing it from working and allowing outdoor fresh air to be directly introduced into the room, thereby saving energy. In this case, if... Figure 12As shown, the first damper 2224 and the second damper 2225 can also be opened simultaneously to increase the air volume.

[0068] The fresh air damper 2104 can be positioned between the fresh air outlet 2102 and the vent 2103, and can move between a fresh air open position and a fresh air closed position. When the fresh air damper 2104 is in the fresh air open position, as... Figure 10 As shown, the fresh air damper 2104 opens the fresh air outlet 2102 and closes the vent 2103. Therefore, when using the fresh air function, it prevents fresh air from entering the sealed cavity, allowing fresh air to enter the room directly from the fresh air outlet 2102, thus shortening the fresh air introduction path and improving the efficiency of delivering fresh air into the room. When the fresh air damper 2104 is in the fresh air closed position, as... Figure 11 As shown, the fresh air damper 2104 closes the fresh air outlet 2102 and opens the vent 2103. This prevents the air from the fan 2220 from entering the room when the fresh air function is not in use, thereby improving the heat insulation efficiency of the window curtain.

[0069] It should be noted that the aforementioned fresh air damper 2104 can be manually controlled or automatically controlled by a motor or other drive components; no limitation is made here.

[0070] In order to filter fresh air, such as Figure 12 As shown, an air filtration module 2105 can also be installed along the fresh air intake path. Specifically, the air filtration module 2105 can be installed at the fresh air inlet or the fresh air outlet, or it can be installed at both the fresh air inlet and the fresh air outlet. This allows outdoor fresh air to be filtered before being introduced indoors, preventing impurities from the outdoor air from entering the room.

[0071] Specifically, the air filtration module may include one or more of the following: a filter mesh layer, a photocatalyst layer, an activated carbon layer, and a filter sponge layer, all stacked together. The filter mesh layer can filter larger impurities in the air, such as leaves. The photocatalyst layer can decompose some organic compounds, some inorganic compounds, bacteria, and viruses in the air. The activated carbon layer can adsorb suspended particles, formaldehyde, and other harmful substances in the air. The filter sponge layer can adsorb excess moisture in the air.

[0072] The solar energy device 2800 can be directly and / or indirectly (e.g., via housing 2100) mounted on the window curtain device 1000, and directly or indirectly (e.g., via power supply device 2300) electrically connected to the cooling device 2200. When operating, the solar energy device 2800 absorbs external solar energy and converts it into electrical energy to generate a required voltage and output current to power the cooling device 2200. After the solar energy device 2800 stabilizes the voltage to a set range through a solar charging management module, it powers the cooling device 2200 through a charging circuit. The solar energy device 2800 may include the solar charging management module and the charging circuit. Figure 8 As shown, the solar energy device 2800 may further include multiple solar panels 2801. These solar panels can be installed at any position between the window 002 and the window curtain device 1000, facing the outside, to absorb outdoor solar energy and convert it into electrical energy. For example, the solar panels can be installed on a fixed frame 200, for example, around the perimeter of the fixed frame 200. In some embodiments, the solar panels can also be installed on the indoor-facing side of the window curtain device 1000 to absorb indoor light energy and convert it into electrical energy. For example, the solar panels can be installed on a movable frame 400, for example, around the perimeter of the movable frame 400. Furthermore, as... Figure 8 As shown, the solar panel 2801 can also be installed on the outer surface of the housing 2100.

[0073] The solar panel 2801 may be a thin-film solar panel. In some embodiments, the solar panel 2801 may be a crystalline silicon solar panel. The installation location and number of the solar panels 2801 may be adjusted according to actual usage requirements, and this specification does not limit this.

[0074] Solar panel 2801 can also be made of flexible materials. For example, resin-encapsulated amorphous silicon can be laid flat on a substrate made of flexible material to form a flexible solar panel 2801. The flexible solar panel 2801 can be bent and folded. Figure 9 As shown, a flexible solar panel 2801 can be attached to the curtain 600 and move together with the curtain 600 between the first position and the second position. When the flexible solar panel 2801 is attached to the outdoor-facing surface of the curtain 600 and the curtain 600 is in the second position, the flexible solar panel 2801 can absorb outdoor solar energy and convert it into electrical energy to power the cooling device 2200.

[0075] In summary, the solar energy device 2800 can make full use of renewable solar energy to power the cooling device 2200. While providing the power required for the operation of the heat dissipation device 2000, it does not increase carbon emissions, saves energy consumption, and improves energy-saving effect.

[0076] In some embodiments, the heat dissipation device 2000 may further include a power supply device 2300. The power supply device 2300 may be mounted on the housing 2100. The power supply device 2300 may be electrically connected to both the cooling device 2200 and the solar energy device 2800 to store electrical energy provided by the solar energy device 2800 and to provide electrical energy to the cooling device 2200. The cooling device 2200 may obtain the electrical energy required for operation from the power supply device 2300. For example, the power supply device 2300 may be electrically connected to the thermoelectric cooler 2210 to supply power to the thermoelectric cooler 2210. In some embodiments, the power supply device 2300 may be directly electrically connected to the cooling device 2200. In some embodiments, the power supply device 2300 may be indirectly electrically connected to the cooling device 2200, for example, through a control device 2400, i.e., the power supply device 2300 is electrically connected to the control device 2400, and the control device 2400 is electrically connected to the cooling device.

[0077] In some embodiments, the power supply device 2300 may be a renewable power supply device, such as a rechargeable battery, such as a storage battery, dry cell battery, lithium battery, etc., such as a low-voltage DC rechargeable lithium battery.

[0078] In some embodiments, the power supply device 2300 may also be electrically connected directly or indirectly (via the control device 2400) to the position sensor 2500 to provide power to the position sensor 2500. In some embodiments, the power supply device 2300 may also be electrically connected directly or indirectly (via the control device 2400) to the temperature sensor 2600 to provide power to the temperature sensor 2600. In some embodiments, the power supply device 2300 may also be electrically connected directly or indirectly (via the control device 2400) to the drive mechanism of the transmission mechanism 900 to provide power to the drive mechanism. The number of power supply devices 2300 may be one or more. The power supply devices 2300 may be installed at any position on the housing 2100. Specifically, the number and position of the power supply devices 2300 may be adjusted and arranged according to the number and position of the devices (cooling device 2200, control device 2400, position sensor 2500, temperature sensor 2600, and drive mechanism) electrically connected to the power supply devices 2300. This specification does not limit this arrangement.

[0079] The control device 2400 can be mounted on the housing 2100 and is communicatively connected to the cooling device 2200 during operation to control the start and stop of the cooling device 2200. Specifically, the control device 2400 can be communicatively connected to the thermoelectric cooler 2210 to control the start and stop of the thermoelectric cooler 2210. The control device 2400 can also be electrically connected to the power supply device 2300 to obtain electrical energy from the power supply device 2300. The control device 2400 may include hardware devices with data information processing capabilities and the necessary programs to drive the hardware devices. In some embodiments, the control device 2400 may be a processor.

[0080] The control device 2400 can control the start and stop of the cooling device 2200 based on one or more methods. In some embodiments, the control device 2400 can control the start and stop of the cooling device 2200 based on a timing mode. For example, the control device 2400 can preset the start time and stop time of the cooling device 2200. The start time can be a time range, and the stop time can also be a time range. When the control device 2400 detects that the current time has reached the start time, it controls the cooling device 2200 to start; when the control device 2400 detects that the current time has reached the stop time, it controls the cooling device 2200 to stop. The start time and stop time can be automatically adjusted or manually adjusted during use based on environmental factors such as season, address, climate, orientation, and the glass parameters of window 002.

[0081] In some embodiments, the control device 2400 can control the start and stop of the cooling device 2200 based on a temperature control mode. For example, the control device 2400 can preset a temperature threshold for starting the cooling device 2200. When the control device 2400 detects that the current temperature is higher than the temperature threshold, it controls the cooling device 2200 to start; when the control device 2400 detects that the current temperature is lower than the temperature threshold, it controls the cooling device 2200 to stop. The temperature threshold can be automatically adjusted or manually adjusted during use based on environmental factors such as season, address, climate, orientation, and glass parameters of window 002. The control device 2400 can detect the current temperature through a temperature sensor 2600. The temperature sensor 2600 will be described in detail later.

[0082] In some embodiments, the control device 2400 can simultaneously control the start and stop of the cooling device 2200 based on the timing mode and the temperature control mode.

[0083] As previously described, when the curtain 600 reaches the second position and completely covers the target window 003, the fixed frame 200 and the movable frame 400 clamp the curtain 600, forming a sealed connection between the curtain 600 and the target window 003, eliminating any gaps between them. At this time, a sealed cavity is formed between the curtain device 1000 and the window 002. The purpose of the cooling device 2200 is to cool the sealed air within this cavity; it needs to be activated only after the curtain device 1000 is in the second position and a sealed cavity has been formed between it and the window 002. Therefore, the control device 2400 can detect the position of the curtain device 1000 to determine whether it fully covers the target window 003. The cooling device 2200 is only activated when the curtain device 1000 fully covers the target window 003. Specifically, the control device 2400 can detect whether the window curtain device 1000 fully covers the target window 003 via the position sensor 2500. The position sensor 2500 will be described in detail later.

[0084] In some embodiments, the control device 2400 may also be connected to the drive mechanism in the curtain wall device 1000 to control the driving force of the drive mechanism.

[0085] In some embodiments, the heat dissipation device 2000 may further include at least one position sensor 2500. The number of position sensors 2500 can be adjusted according to actual usage requirements. At least one position sensor 2500 may be mounted on the curtain device 1000. When the at least one position sensor 2500 is operating, it can communicate with the control device 2400 to detect the position of the curtain device 1000 and send the position data to the control device 2400 to determine whether the curtain device 1000 completely blocks the target window 003. When the control device 2400 determines that the curtain device 1000 completely blocks the target window 003, the control device 2400 controls the cooling device 2200 to start. In some embodiments, the position sensor 2500 may be mounted on the lower side of the curtain device 1000, for example, at the second position, to detect whether the curtain 600 is in the second position. The position sensor 2500 can be any sensor capable of measuring position, such as a distance sensor, for example, an infrared distance sensor, a radar distance sensor, an ultrasonic distance sensor, etc. For example, sensing sensors, such as infrared sensors, radar sensors, ultrasonic sensors, etc. Taking position sensor 2500 as an example, which is an infrared sensor, the infrared sensor can be installed at the bottom of the fixed frame 200 and emit infrared light towards the indoor side of the curtain wall device 1000. When the curtain wall device 1000 is in the second position and completely blocks the target window 003, the position data monitored by the infrared sensor will change. The control device 2400 can determine whether the curtain wall device 1000 completely blocks the target window 003 based on the change in the position data of the infrared sensor.

[0086] In some embodiments, the position sensor 2500 can be installed at any position on the curtain device 1000 to detect whether the curtain 600 is in the second position. The position sensor 2500 can be a magnetic body and a magnetic induction sensor, such as a Hall sensor. The Hall sensor can sense the magnetic body and output sensing data (i.e., the position data). When the distance between the magnetic body and the Hall sensor is greater than a preset distance value, the Hall sensor cannot sense the magnetic body and outputs first position data. When the distance between the magnetic body and the Hall sensor is less than the preset distance value, the Hall sensor senses the magnetic body and outputs second position data. As mentioned above, when the curtain 600 reaches the second position, the movable frame 400 approaches the fixed frame 200 and clamps the curtain 600 with the fixed frame 200. The magnetic body and the Hall sensor can be installed at any position on the fixed frame 200 and the movable frame 400, respectively, and the magnetic body and the Hall sensor are arranged opposite to each other. When the curtain 600 reaches the second position, the Hall sensor can sense the oppositely arranged magnetic body and output the second position data. Based on the second position data, the control device 2400 determines that the curtain device 1000 fully occludes the target window 003.

[0087] In some embodiments, such as in the timing mode described above, when the control device 2400 determines that the curtain device 1000 completely blocks the target window 003 through the position data of at least one position sensor 2500, and determines that the current time is within a preset time range (the time range corresponding to the start time), the control device 2400 can control the cooling device 2200 to start.

[0088] In some embodiments, the heat dissipation device 2000 may further include at least one temperature sensor 2600. The number of temperature sensors 2600 can be adjusted according to actual usage requirements. At least one temperature sensor 2600 can be mounted on the housing 2100. Specifically, at least one temperature sensor 2600 can be mounted at any location on the housing 2100. In some embodiments, the temperature sensor 2600 can be mounted between the window curtain device 1000 and the window 002 to measure the temperature of the sealed air between the window 002 and the window curtain device 1000. When operating, the temperature sensor 2600 can communicate with the control device 2400 to monitor the temperature data of the sealed air and send the temperature data to the control device 2400. In some embodiments, the temperature sensor 2600 can be mounted on the window curtain device 1000 and facing indoors to measure the indoor temperature and send the indoor temperature data to the control device 2400. In some embodiments, the temperature sensor 2600 can be mounted both between the window curtain device 1000 and the window 002 and on the window curtain device 1000, facing indoors. For ease of description, we will install the temperature sensor 2600 between the window curtain device 1000 and the window 002, and use the measurement of the temperature of the sealed air between the window 002 and the window curtain device 1000 as an example for illustration.

[0089] In some embodiments, such as in the temperature control mode described above, when the control device 2400 determines that the curtain device 1000 completely blocks the target window 003 through the position data of at least one position sensor 2500, and determines through the temperature data monitored by at least one temperature sensor 2600 that the temperature of the sealed air is higher than a set temperature threshold, the control device 2400 can control the cooling device 2200 to start.

[0090] It should be noted that in some embodiments, the start and stop of the cooling device 2200 can be controlled manually.

[0091] In some embodiments, the heat dissipation device 2000 may further include a thermal power generation device 2900. The thermal power generation device 2900 may be mounted on the housing 2100. The thermal power generation device 2900 may be electrically connected to the power supply device 2300 and configured to absorb heat from the heating end 2212 and convert the heat into electrical energy to charge the power supply device 2300. The thermal power generation device 2900 may include a thermal storage device 2920 and a thermoelectric generator 2940.

[0092] The heat storage device 2920 can be connected to the heating end 2212, absorbing and storing the heat from the heating end 2212 during operation. When the stored heat reaches a preset value, the heat storage device releases heat outwards. The heat storage device 2920 may include a heat collection unit and a heat storage unit. The two ends of the heat collection unit can be connected to the heating end 2212 and the heat storage unit respectively, to absorb heat from the heating end 2212 and conduct the heat to the heat storage unit. The heat collection unit can evenly conduct the heat to the heat storage unit. In some embodiments, the heat collection unit can be a high-temperature, high-efficiency conductive material. In some embodiments, the heat collection unit can be a heat spreader material.

[0093] The heat storage unit can absorb and store the heat transferred by the heat collection unit. In some embodiments, the heat storage unit can be a device composed of phase change material. In some embodiments, the heat storage unit is filled with phase change material. When the heat from the heating end 2212 is transferred to the phase change material through the heat collection unit, the phase change material absorbs heat and undergoes a phase change, storing the heat. The phase change material container is wrapped with an insulating material to prevent heat loss. In some embodiments, the phase change material is surrounded by insulating material. When the temperature outside the heat storage unit reaches a set temperature for releasing heat, the phase change material in the heat storage unit releases latent heat of phase change. The preset value can be the set temperature for releasing heat. In some embodiments, a suitable temperature for releasing heat from the phase change material can be selected based on geographical location, building orientation, and glass parameters, allowing it to absorb heat during the day and release heat at night when the temperature drops to the set temperature. For example, the phase change material filled in the heat storage unit can be selected according to the local temperature. For example, in Beijing summers, the temperature is about 22 degrees Celsius or higher after 10 am and drops to below 22 degrees Celsius by 6 pm. Therefore, the release temperature of the phase change material can be set to 22 degrees Celsius, so that it will absorb heat after 10 am and release heat after 6 pm.

[0094] In some embodiments, the phase change material inside the thermal storage unit is one or more of paraffin, fatty acids, and inorganic salts with water of crystallization. In some embodiments, the phase change material inside the thermal storage unit is a material with a melting point range of 10-90°C.

[0095] In some embodiments, the thermoelectric generator 2940 can be a thermoelectric power generation device made of semiconductor material. According to the Seebeck effect, a voltage difference arises between two different conductors or semiconductors due to their temperature differences. Therefore, when the two ends of the thermoelectric generator 2940 are simultaneously exposed to different temperatures, a current loop is formed inside the thermoelectric generator 2940, and the greater the temperature difference, the stronger the current generated. Thus, by generating a temperature difference across the two ends of the thermoelectric generator 2940, the mutual conversion of thermal energy and electrical energy can be achieved. The thermoelectric generator 2940 may include a first end and a second end. The first end can be connected to a thermal storage device 2920, and the second end is electrically connected to a power supply device 2300. When the heat stored in the thermal storage device 2920 reaches the preset value, the thermal storage device 2920 releases heat to the first end, causing the temperature of the first end to rise; the thermoelectric generator 2940 generates electrical energy under the temperature difference between the first end and the second end to charge the power supply device 2300.

[0096] In some embodiments, the materials of the first and second ends of the thermoelectric power generation device 2940 can be nanoporous thermoelectric materials. The thermoelectric materials are thermoelectric chips connected in series and arrayed in the power generation section. The thermoelectric chips simultaneously contact a cold source and a heat source to generate a temperature difference, thereby initiating power generation. The electricity is then conducted through wires to charge the power supply device 2300. In some embodiments, multiple thermoelectric power generation devices 2940 can be provided to improve charging efficiency.

[0097] In summary, in the thermal power generation device 2900, when the temperature of the sealed air exceeds the temperature threshold, the semiconductor cooler 2210 is activated, cooling the sealed air through the cooling end 2211 and generating heat at the heating end 2212. The heat from the heating end 2212 is transferred to and stored in the thermal storage device 2920. When the heat stored in the thermal storage device 2920 reaches a preset value, it releases heat and generates electricity through the thermoelectric generator 2940 to charge the power supply device 2300. For example, when the temperature is high during the day, the cooling device 2200 is activated, and heat is stored in the thermal storage device 2920; when the temperature drops at night, the cooling device 2200 stops, the heat stored in the thermal storage device 2920 reaches the preset value, and the thermal storage device 2920 releases heat, creating a temperature difference across the thermoelectric generator 2940 to charge the power supply device 2300. The thermal power generation device 2900 can make full use of the heat generated by the cooling device 2200 during operation and reuse the heat to charge the power supply device 2300, so as to make full use of energy, reduce energy consumption, and improve energy saving effect.

[0098] In summary, the power supply device 2300 is charged alternately by the solar energy device 2800 and the thermal power generation device 2900. When there is solar energy, the solar energy device 2800 is used to charge the power supply device 2300. When there is no solar energy (such as at night) or when solar energy is insufficient, the thermal power generation device 2900 uses the heat generated by the cooling device 2200 to charge the power supply device 2300, so as to achieve a continuous supply of electricity.

[0099] In summary, the solar-powered energy-saving window curtain 001 provided in this specification includes a heat dissipation device 2000 installed between the window curtain device 1000 and the window 002, powered by a solar energy device 2800 and a thermal power generation device 2900. When the window curtain device 1000 completely covers the target window 003, the cooling device 2200 in the heat dissipation device 2000 can cool the sealed air between the window curtain device 1000 and the window 002, thereby reducing the temperature of the sealed air. When the temperature sensor 2600 senses an increase in the temperature of the sealed air, the control device 2400 controls the cooling device 2200 to start and reduce the temperature of the sealed air, preventing heat from the outside of the window 002 from being conducted to the inside of the window curtain device 1000 through the sealed air, thus preventing heat conduction and heat exchange between the window 002 and the window curtain device 1000. Simultaneously, by utilizing renewable energy for power supply, carbon emissions are further reduced, improving energy conservation and emission reduction effects. Meanwhile, the solar-powered energy-saving window curtain 001 provided in this specification can absorb and store the heat generated when the cooling device 2200 is working through the thermal power generation device 2900, and charge the power supply device 2300 based on the heat, so as to recover and reuse the heat generated when the cooling device 2200 is working, thereby making full use of energy, reducing carbon emissions, and improving energy-saving effect.
