Abstract
Description
Technical Field
[0001] This invention relates to the field of building energy conservation technology under green technology, and more specifically, to an insulated window sash for closing openings. Background Technology
[0002] Existing buildings are all equipped with windows, which increase indoor lighting and improve living comfort. However, in summer, sunlight indirectly raises the atmospheric temperature by continuously heating the ground. Windows, in contact with the atmosphere, exchange heat, transferring heat from the outside to the inside, thus increasing the indoor temperature. Secondly, infrared radiation from sunlight is a major source of heat radiation, and existing windows cannot block it. Sunlight penetrates the glass and shines into the room, further increasing the indoor temperature due to the heat contained in the infrared rays, resulting in a heat accumulation effect. This heat accumulation leads to decreased efficiency of indoor air conditioning, increased energy consumption, and is detrimental to environmental protection and energy conservation, failing to meet green technology requirements.
[0003] To address these issues, various types of insulated windows have emerged, such as double-glazed windows and Low-E coated windows. Both types feature double-glazed windows with inert gas filling the space between the glass and the outside air to reduce heat exchange efficiency and improve insulation. Low-E coated windows also have a silver or aluminum film coating on the glass, blocking 80% to 90% of infrared rays from sunlight, significantly reducing infrared radiation entering the room. However, the insulation performance of double-glazed windows is still not ideal because the inert gas filling them is itself a thermally conductive medium, with a heat transfer coefficient typically between 2.8 and 3.0 W / m²·K. Although the heat transfer coefficient of Low-E coated heat-insulating windows is 1.4-1.8W / m²·K, which is a significant improvement over the heat insulation capacity of insulated double-glazed windows, the metal coating on its surface not only blocks infrared rays from entering the room, but also prevents indoor electrical signals from being transmitted to the outside, resulting in poor indoor communication signals.
[0004] Therefore, there is a need for a new type of environmentally friendly heat-insulating window to simultaneously solve the problems of indoor heat insulation and poor indoor communication signals. Summary of the Invention
[0005] In view of this, and in order to solve the problems mentioned above, the present invention provides a heat-insulating window sash, the specific technical solution of which is as follows:
[0006] A heat-insulating window sash includes a primary heat-insulating mechanism, a secondary heat-insulating mechanism, and a window frame, wherein the primary heat-insulating mechanism and the secondary heat-insulating mechanism are installed on the window frame;
[0007] The primary insulation mechanism includes heat-dissipating glass and heat-insulating glass. The heat-dissipating glass, heat-insulating glass, and window frame enclose an insulation space, which is used to install the secondary insulation mechanism.
[0008] The secondary insulation mechanism includes a guide assembly, multiple rotating assemblies, multiple heat-reflecting assemblies, and multiple guide rods. The guide assembly includes two guide frames, namely guide frame one and guide frame two. Guide frame one and guide frame two are vertically spaced within the insulation space. Both ends of guide frame one and guide frame two are fixedly connected to the window frame. Multiple rotating assemblies are movably mounted on guide frame one and guide frame two at intervals.
[0009] The heat-reflecting assembly includes a receiving component, a reflecting component, and a first fixing component. The two ends of the first fixing component are rotatably connected to two rotating components respectively. A strip groove is formed in the middle of the first fixing component along the length direction. The reflecting component is fixedly installed in the strip groove and is folded.
[0010] The receiving component is located below the first fixing component, and two fixing parts protrude upward near both ends of the carrier component. The fixing parts are movably connected to the first fixing component. A light-absorbing layer is installed at the bottom of the receiving component. Multiple ventilation ducts are opened inside the receiving component along the length direction. Multiple heat-reflecting components and rotating components are evenly spaced on two guide frames.
[0011] The primary insulation mechanism also includes a fan, which is installed at the bottom of the window frame and the fan's blowing end is biased towards the heat dissipation glass;
[0012] The heat dissipation glass has an air inlet and an air outlet, located at the top and bottom ends of the heat dissipation glass, with the air inlet close to the fan.
[0013] In some embodiments, the guide frame 1 is frame-shaped, and the side of the guide frame 1 facing the heat dissipation glass is an open side, forming a first sliding groove along the length direction; a first moving groove is formed on the side wall of the guide frame 1 facing the guide frame 2 along the length direction, and the first sliding groove and the first moving groove are connected; a first guide groove is formed on the two opposite inner side walls of the first sliding groove along the length direction; the first guide groove and the first moving groove are offset from each other on the guide frame 1.
[0014] The second guide frame is frame-shaped, with the side of the guide frame facing the heat dissipation glass being the open side, forming a second sliding groove along its length; the side of the guide frame facing the first guide frame has a second moving groove along its length, and the second sliding groove and the second moving groove are connected; a second guide groove is formed on each of the two opposite inner sidewalls of the second sliding groove along its length; the second guide groove and the second moving groove are offset from each other on the guide frame; the first moving groove and the second moving groove are arranged opposite each other;
[0015] Multiple rotating components are respectively movably disposed in the first sliding groove and the second sliding groove.
[0016] In some embodiments, the guide assembly further includes two drive devices, which are respectively disposed at the bottom of guide frame one and guide frame two, and the drive ends of the two drive devices extend into the first sliding groove and the second sliding groove, respectively.
[0017] In some embodiments, the rotating assembly includes a carrier component, a rack, and an expansion component. The carrier component is movably disposed in a first sliding groove. Sliding portions are protruding from two opposite sides of the carrier component. The sliding portions are slidably adapted to the guide groove. A telescopic groove is provided on the top of the carrier component, and a snap-fit groove is provided on the bottom of the carrier component. The snap-fit groove and the telescopic groove are vertically aligned in the height direction. The cross-section of the telescopic groove is convex, that is, the inner diameter of the opening of the telescopic groove is smaller than the inner diameter of the bottom of the telescopic groove. A rotating groove is also provided on the side of the carrier component where the sliding portion protrudes. The cross-section of the rotating groove is circular. The rotating groove and the sliding portion are offset and disposed on the same side of the carrier component.
[0018] The carrier component has a movable groove opened in the horizontal direction, and the movable groove is perpendicularly connected to the rotating groove. The rack is installed in the movable groove.
[0019] The expansion component is installed at the end of the movable groove and is fixedly connected to one end of the rack. When the expansion component is heated and expands, it can drive the rack to move.
[0020] A guide rod is installed between every two adjacent carrier components. The two ends of the guide rod are a connecting end and a movable end, respectively. The cross-section of the movable end of the guide rod is "T" shaped. The movable end of the guide rod is in movable fit with the expansion groove of one carrier component, and the connecting end of the guide rod is in snap-fit connection with the snap-fit groove of another carrier component.
[0021] In some embodiments, a first balance plate protrudes from the inner wall of the top of the first sliding groove, and a second balance plate protrudes from the inner wall of the top of the second sliding groove, with the first balance plate and the second balance plate being flush in the horizontal direction.
[0022] In some embodiments, a carrier component in the first sliding groove is fixedly disposed on the first balance plate, and a carrier component in the second sliding groove is fixedly disposed on the second balance plate.
[0023] In some embodiments, the first fixing member is a square frame with an opening on the upper side, and two cylindrical rollers, roller one and roller two, are respectively protruding from both ends. A gear is provided at the end of roller one and another gear is provided at the end of roller two. The positions and structures of roller one and roller two are symmetrical with respect to the first fixing member. The gears on roller one and roller two mesh with the racks in the corresponding carrier members.
[0024] In some embodiments, the first roller shaft passes through the first moving groove and is movably connected to the carrier component in the first sliding groove, and the second roller shaft passes through the second moving groove and is movably connected to the carrier component in the second sliding groove.
[0025] In some embodiments, the ventilation duct extends through both ends of the receiver, and the radial cross-section of the ventilation duct is frustum-shaped.

[0027] The beneficial effects of this solution are as follows: the heat-insulating space formed by the heat-dissipating glass and the heat-insulating glass initially blocks high-temperature airflow from entering the room. The guiding component, rotating component, and heat-reflecting component work together to block sunlight. Sunlight shines on the reflector, which reflects the sunlight to the receiver, preventing direct sunlight from entering the room. The ventilation duct on the receiver lowers its own temperature, and the fan blows the heat away, thus achieving the heat insulation effect. Compared to existing technologies, this application uses the combination of heat-reflecting and rotating components to ensure that the reflection angle of the heat-reflecting component always corresponds to the angle of sunlight, thus achieving heat insulation while maintaining uninterrupted communication signals.

[0047] Example
[0048] like Figure 1 and Figure 2 As shown, an insulated window sash includes a primary insulation mechanism 1, a secondary insulation mechanism 2, and a window frame 3, wherein the primary insulation mechanism 1 and the secondary insulation mechanism 2 are installed on the window frame 3.
[0049] like Figures 1 to 3 As shown, the primary heat insulation mechanism 1 includes a heat dissipation glass 11, a heat insulation glass 12, and a fan 13, wherein... Figure 2 The heat dissipation glass 11 is not shown in the image; instead, it is displayed separately as shown in the image. Figure 3 During installation, the heat dissipation glass 11 and the heat insulation glass 12 are respectively along... Figure 2 The window frame 3 shown is surrounded by a series of heat-dissipating glass 11, heat-insulating glass 12, and window frame 3, forming an insulation space 4. The heat-dissipating glass 11 is in contact with the outdoor air, while the heat-insulating glass 12 is away from the outdoor air (i.e., facing inwards). The distance between the heat-dissipating glass 11 and the heat-insulating glass 12 is 8cm to 12cm. The insulation space 4 is used to install the secondary insulation mechanism 2. The fan 13 is installed in the insulation space 4, and the fan 13 is located at the bottom of the window frame 3. The air outlet 112 of the fan 13 is biased towards one side of the heat-dissipating glass 11, and the airflow direction of the fan 13 is tilted towards the heat-dissipating glass 11.
[0050] like Figures 1-3 As shown, the heat dissipation glass 11 has an air inlet 111 and an air outlet 112. The air inlet 111 is located at the lower part of the heat dissipation glass 11 (at the bottom of the window frame 3), close to the fan 13, and the air outlet 112 is located at the upper part of the heat dissipation glass 11.
[0051] The airflow direction of the fan 13 is from bottom to top, that is, the fan 13 blows air from the air inlet 111 toward the air outlet 112. The airflow will form a heat-insulating film to prevent the heat of the air in the heat-insulating space 4 from exchanging heat with the heat-insulating glass 12. The airflow blown by the fan 13 drives the hot air inside the heat-insulating space 4 to be blown out of the air outlet 112 to the outdoor air, so as to prevent the hot air from exchanging heat with the heat-insulating glass 12 and causing the indoor temperature to rise.
[0052] like Figure 1 and Figure 4 As shown, the secondary heat insulation mechanism 2 includes a guide assembly 21, multiple rotating assemblies 22, multiple heat-reflecting assemblies 23, and multiple guide rods 24; the multiple rotating assemblies 22, heat-reflecting assemblies 23, and guide rods 24 are respectively disposed on the guide assembly 21.
[0053] like Figure 4 As shown, the guide assembly 21 includes two guide frames and two drive devices (not shown in the figure). The two guide frames are guide frame one 100 and guide frame two 200, which are vertically spaced on both sides of the heat insulation space 4. The upper and lower ends of guide frame one 100 are fixedly connected to the window frame 3, and the upper and lower ends of guide frame two 200 are fixedly connected to the window frame 3. The guide frame one 100 and guide frame two 200 have the same structure.
[0054] See appendix Figure 4 The guide frame 100 is frame-shaped, with the side of the guide frame 100 facing the heat dissipation glass 11 being an open side, forming a first sliding groove 101 along its length; a first moving groove 102 is formed on the side wall of the guide frame 100 facing the guide frame 200 along its length, and the first sliding groove 101 and the first moving groove 102 are connected; a first guide groove 103 is formed on the two opposite inner side walls of the first sliding groove 101 along its length; the first guide groove 103 and the first moving groove 102 are offset from each other on the guide frame 100; a first balance plate 104 is protruding from the inner side wall at the top of the first sliding groove 101.
[0055] See appendix Figure 4The second guide frame 200 is frame-shaped, with an open side facing the heat dissipation glass 11, forming a second sliding groove 201 along its length. A second moving groove 202 is formed along the length of one side wall of the second guide frame 200 facing the first guide frame 100, and the second sliding groove 201 and the second moving groove 202 are connected. Second guide grooves 203 are formed along the length of two opposite inner side walls of the second sliding groove 201. The second guide grooves 203 and the second moving grooves 202 are offset from each other on the second guide frame 200. A second balancing plate 204 protrudes from the inner wall at the top of the second sliding groove 201, and the first balancing plate 104 and the second balancing plate 204 are flush in the horizontal direction. The first moving groove 102 and the second moving groove 202 are set facing each other.
[0056] One drive unit is located at the end of guide frame 100 away from the first balance plate 104, and the other drive unit is located at the end of guide frame 200 away from the second balance plate 204. The drive parts of the two drive units extend into the first sliding groove 101 and the second sliding groove 201, respectively. That is, the two drive units are located at the bottom of guide frame 100 and guide frame 200, respectively.
[0057] like Figure 4 As shown, multiple rotating components 22 are respectively and movably installed in the first sliding groove 101 and the second sliding groove 201 at intervals along the length direction.
[0058] like Figure 5 and Figure 7 As shown, the rotating assembly 22 includes a carrier component 221, a rack 222, and an expansion component 223. Multiple carrier components 221 are respectively movably disposed in the first sliding groove 101 and the second sliding groove 201 (e.g., ...). Figure 4 As shown), sliding portions 2211 protrude from two opposite sides of the carrier component 221 (see attached diagram). Figure 7 (as indicated by the annotation), the sliding portion 2211 of each carrier component 221 is adapted to the first guide groove 103 and the second guide groove 203. The sliding portion 2211 cooperates with the first guide groove 103 or the second guide groove 203 to allow the carrier component 221 to move along the first sliding groove 101 or the second sliding groove 201. The carrier component 221 installed in the first guide groove 103 and the carrier component 221 installed in the second guide groove 203 are horizontally opposite each other. See Appendix Figure 4 .
[0059] like Figures 9 to 11 As shown, the top of the carrier component 221 is provided with a telescopic groove 2212 (see attached diagram). Figure 11 (The label indicates that the bottom of the carrier component 221 is provided with a snap-fit groove 2213 (see attached)). Figure 9 and attached Figure 11(as indicated by the markings), the snap-fit groove 2213 and the telescopic groove 2212 are aligned vertically in the height direction; the cross-section of the telescopic groove 2212 is convex, that is, the inner diameter of the opening of the telescopic groove 2212 is smaller than the inner diameter of the bottom of the telescopic groove 2212.
[0060] A rotating groove 2214 is provided on one side of the carrier component 221 (see Appendix). Figure 9 The rotating groove 2214 has a circular cross-section, and the rotating groove 2214 and the sliding part 2211 are spaced apart on the same side of the carrier 221 (see Appendix). Figure 9 ). Figure 8 yes Figure 5 A cross-sectional view of the rotating assembly 22 along the AA direction is shown in the attached diagram. Figure 8 The carrier component 221 has a horizontally oriented movable groove 2215 inside, which is perpendicularly connected to the rotating groove 2214. The rack 222 is installed in the movable groove 2215. The expansion component 223 is installed at the end of the movable groove 2215 and is fixedly connected to one end of the rack 222. When the expansion component 223 is heated and expands, it can drive the rack 222 to move.
[0061] See appendix for further details. Figure 8 The expansion element 223 is a bimetallic strip. When heated, the bimetallic strip bends due to their different coefficients of expansion, thereby driving the rack 222 to move. After the expansion element 223 deforms due to heat, it overcomes the friction between the gear 2331 (the setting method is described below) and the rack 222 to drive the rack 222 to move, which in turn drives the gear 2331 to rotate.
[0062] The reflector 232 has a length of 1m, a width of 0.1m, a thickness of 0.03m, and a weight of 204g. The first fixing member 233 has a length of 1.04m, a width of 0.14m, a thickness of 0.04m, and a weight of 417g. The gear 2332 has an outer diameter of 3.5cm. The bimetallic strips are made of brass and Invar alloy, respectively. Due to the large difference in their coefficients of thermal expansion, the bimetallic strips are bent to drive the rack to move, thereby driving the sun visor to rotate. The brass strips have a length of 0.13m, the Invar alloy strips have a length of 0.13m, and the bimetallic strips have a thickness of 1mm.
[0063] When the temperature is 20℃, the displacement of rack 222 is 0mm.
[0064] When the temperature is 30℃, the displacement distance of rack 222 is 3.04mm;
[0065] When the temperature is 40℃, the displacement distance of rack 222 is 6.08mm;
[0066] When the temperature is 50 °C, the displacement distance of the rack 222 is 9.12 mm;
[0067] When the temperature is 60 °C, the displacement distance of the rack 222 is 12.16 mm;
[0068] When the temperature is 70 °C, the displacement distance of the rack 222 is 15.21 mm;
[0069] When the temperature is 80 °C, the displacement distance of the rack 222 is 18.25 mm.
[0070] Secondly, a small motor can also be arranged in the carrier member 221. The driving end of the small motor is connected to the rack 222, and the expansion member 223 faces the switch of the small motor; after the expansion member 223 expands due to heat, it presses against the switch of the small motor, causing the small motor to be powered on to drive the movement of the rack 222.
[0071] As Figure 10 and 11 shown, a guide rod 24 is arranged between every two carrier members 221. The two ends of the guide rod 24 are respectively a connection end and a movable end. The cross-section of the movable end of the guide rod 24 is in a "T" shape, and the movable end of the guide rod 24 is movably matched with the telescopic groove 2212 of a carrier member 221. Refer to the appendix Figure 11 The narrow part of the opening of the "convex" - shaped telescopic groove 2212 blocks the movable end from moving out of the telescopic groove 2212. Refer to the appendix Figure 11 The connection end of the guide rod 24 is snap - connected to the snap - fit groove 2213 of another carrier member 221. Among them, the fixing method of the guide rod 24 and the carrier member 221 can be thread - fitting, and the fixing method of the guide rod 24 and the snap - fit groove 2213 can be various.
[0072] As Figure 4 show, the multiple carrier members 221 in the first sliding groove 101 are successively connected in series through multiple guide rods 24, and the multiple carrier members 221 in the second sliding groove 201 are successively connected in series through multiple guide rods 24.
[0073] Figure 4 As Figure 9 shown, the multiple carrier members 221 in the first sliding groove 101 and the multiple carrier members 221 in the second sliding groove 201 are horizontally corresponding one by one and vertically corresponding one by one. One carrier member 221 in the first sliding groove 101 is fixedly arranged on the first balance plate 104, and one carrier member 221 in the second sliding groove 201 is fixedly arranged on the second balance plate 204. The first balance plate 104 and the second balance plate 204 play a role in supporting the carrier memberThey are respectively directly opposite the first sliding groove 101 and the second sliding groove 201.
[0074] See appendix Figure 8 The rack 222 can move relative to the movable groove 2215 in two ways: one side of the rack 222 can be movably engaged with the inner top wall of the movable groove 2215, and the expansion member 223 can drive the rack 222 to move along the movable groove 2215 after being heated and deformed. Alternatively, a sliding hole can be provided through the rack 222, and a connecting rod can be passed through the sliding hole to connect the rack 222. The two ends of the connecting rod are provided on the two opposite inner side walls of the movable groove 2215, avoiding direct contact between the rack 222 and the inner top wall of the movable groove 2215, thereby reducing the friction force experienced by the expansion member 223 when pushing the rack 222 and improving the service life of the expansion member 223.
[0075] like Figure 5-6 As shown, the heat-reflecting assembly 23 includes a receiving component 231, a reflecting component 232, four bearings 700, a first fixing component 233, and two gears 2331. The first fixing component 233 is a square frame with an opening on the upper side, and cylindrical roller shaft 500 and roller shaft 600 protrude from both ends respectively (see Appendix). Figure 6 (as indicated by the label), a gear 2331 is provided at the end of roller 500, and another gear 2331 is provided at the end of roller 600. The positions and structures of roller 500 and roller 600 are symmetrical with respect to the first fixing member 233. A strip groove 2332 is formed along the length direction in the middle of the first fixing member 233. The reflector 232 is fixedly installed in the strip groove 2332, for example, on its bottom surface. Two bearings 700 are respectively sleeved on the side walls of roller 500 and roller 600. See Appendix Figure 4 Roller shaft 500 passes through the first moving groove 102 and is movably connected to the carrier component 221 in the first sliding groove 101. Roller shaft 600 passes through the second moving groove 202 and is movably connected to the carrier component 221 in the second sliding groove 201. See also Figure 7 The specific connection method is as follows: a bearing 700 on roller shaft 500 and roller shaft 600 is interference-fitted with the side wall of the rotating groove 2214. See details for further information. Figures 6 to 8 As shown, the gears 2331 on roller shaft 500 and roller shaft 600 respectively mesh with the racks 222 in the corresponding carrier component 221. When the expansion component 223 expands due to heat and pushes the rack 222 along the movable groove 2215, the rack 222 will drive the gears 2331 to rotate, and the gears 2331 will drive the first fixed component 233 to rotate as a whole.
[0076] like Figure 6As shown, the receiving component 231 is cuboid in shape and is located below the first fixing component 233. Two fixing portions 2311 are integrally protruding upwards from both ends of the receiving component 231 near the carrier component 221. Two rollers (500, 600) pass through their respective fixing portions 2311. Roller 500 and roller 600 are respectively press-fitted with their respective fixing portions 2311 via a bearing 700 (see attached diagram for details). Figure 5 Roller shaft 500 and roller shaft 600 are respectively movably connected to their respective carrier components 221 via bearings 700 (see appendix for details). Figure 5 The receiver 231 has a light-absorbing layer at its bottom; multiple ventilation ducts 2312 are formed along the length of the receiver 231, and the ventilation ducts 2312 pass through both ends of the receiver 231 (see Appendix). Figure 6 ).
[0077] See appendix Figure 4 Multiple heat-reflecting components 23 are arranged at intervals along the guide frame 100 and guide frame 200, and each heat-reflecting component 23 corresponds to a set of carrier components 221.
[0078] The reflector 232 is made of polycarbonate, which has the advantages of being lightweight and having high reflectivity. By adjusting it to an angle that matches the direction of sunlight incidence, it can effectively reflect sunlight onto the light-absorbing layer of the adjacent receiver 231 above it, thereby preventing sunlight from entering the room and increasing the temperature of the receiver 231. (See details...) Figure 12 As shown, Figure 12 This is a schematic diagram of the sun-reflecting component 23 according to an embodiment of the present invention. Two adjacent sets of sun-reflecting components 23 are selected for explanation. The arrows represent light incident and reflection. The cross-section of the reflector 232 is folded, and the folding angle of the reflector 232 is 120° to 145°. The height of the first fixing component 233 is 2cm, and the width of the first fixing component 233 is 5cm. The thickness of the receiver 231 is 3cm, and the width of the receiver 231 is 5cm. The height of the fixing part 2311 of the receiver 231 is 3cm. That is, the distance between the receiver 231 and the first fixing component 233 is close to 3cm, ensuring sufficient space for the first fixing component 233 to avoid obstruction when rotating. The length of the guide rod 24 is 4cm, and the distance between the two sets of rotating components 22 is 3cm.
[0079] In the following text, the solar altitude angle is defined as the angle between the sun and the horizon. The larger the solar altitude angle, the more direct the sunlight and the higher the thermal radiation.
[0080] In the following definition, the angle of incidence of the sun refers to the angle between sunlight and the window; the higher the temperature, the smaller the angle of incidence of the sun.
[0081] When the first fixing member 233 rotates to the maximum rotation angle of 60° (i.e., attached) Figure 12The rotation angle of the first fixing member 233 (and the spacing between the first fixing member 233 and the receiver 231) is 0.7 cm, which effectively prevents the first fixing member 233 from colliding with the receiver 231 located above and below it. The width of both the first fixing member 233 and the receiver 231 is 5 cm. When the solar altitude angle is 80°, the solar thermal radiation reaches its maximum (corresponding to noon in summer). At this time, the solar incident angle is 10°, and the reflector 232 in the first fixing member 233 can effectively reflect sunlight onto the receiver 231. When the solar altitude angle is 30° to 60°, the solar thermal radiation decreases (corresponding to shortly after sunrise or when the sun is about to set). The solar incident angle is 60° to 30°. Sunlight can pass through the gaps between the heat insulation components and enter the room, but because the solar thermal radiation is low at this time, it has little impact on the indoor temperature. The reflector 232 reflects sunlight onto the receiver 231. Therefore, the receiver 231 will be exposed to sunlight from the outside and sunlight reflected by the reflector 232. The temperature of the receiver 231 will reach 65℃~75℃. The ventilation duct 2312 can promote the heat dissipation and temperature drop of the receiver 231.
[0082] The reflector 232 and receiver 231 work together to better transport the high-temperature gas out of the heat-insulating space 4. The principle is that, for example... Figure 1 and Figure 12 As shown, the reflector 232 reflects sunlight onto the receiver 231 to block some of the infrared rays from entering the room. A small portion of sunlight (including some scattered light) can still enter the room through the gaps between the first fixing member 233 and the reflector 232, as well as the gaps between the multiple heat-reflecting components 23, ensuring a certain amount of natural light. The radial cross-section of the ventilation duct 2312 in the receiver 231 is frustum-shaped. Airflow from the large opening of the ventilation duct 2312 will flow towards the small opening. This is because the air at the large opening of the ventilation duct 2312 expands due to heat, resulting in a larger surface area, while the air at the small opening expands due to heat, resulting in a smaller surface area. Heated air continuously flows into the small opening and exits from it. Thus, airflow continuously passes through the ventilation duct 2312, quickly transferring heat to the insulated space 4. The high-temperature airflow is then blown out by the fan 13, thereby reducing the temperature of the insulated space 4.
[0083] like Figure 4 and Figure 11 As shown, when efficient insulation of outdoor temperature is not required, multiple carrier components 221 can be folded together, see Appendix. Figure 4 Since the two uppermost carrier components 221 are respectively supported on the first balance plate 104 and the second balance plate 204, see also the attached document. Figure 11The lower carrier component 221 is suspended by the guide rod 24. The lower part of the guide rod 24 and the bottom of the telescopic groove 2212 have a return space. Therefore, the drive device can drive multiple carrier components 221 from the bottom to retract towards the uppermost carrier component 221 to allow as much light as possible to pass through and increase the amount of light. The vertical position of multiple carrier components 221 relative to the guide frame 100 and the guide frame 200 can also be adjusted according to the angle of sunlight incidence to fully reflect light.
[0084] During midday in summer, the temperature of the expansion member 223 after continuous heating ranges from 40°C to 78°C. When the temperature of the expansion member 223 reaches 78°C, it expands to its maximum volume. The first fixing member 233 rotates to its maximum angle under the drive of the rack 222. The reflector 232 forms an angle of 50° to 60° with the horizontal plane, reflecting some sunlight onto the receiver 231 to increase its temperature. This causes the airflow around the receiver 231 to expand and rise due to the high temperature. The airflow blown by the fan 13 forms a downward airflow gradient inside the heat dissipation glass 11, which, together with the upward hot airflow around the receiver 231, forms a spiral airflow that overlaps in the same direction, accelerating the movement of the hot airflow toward the air outlet 112 of the heat dissipation glass 11. After passing through the rotating assembly 22, the mixed airflow will be discharged from the air outlet 112. As the air pressure in the heat insulation space 4 decreases after the mixed airflow is discharged from the air outlet 112, air will be drawn in from the air inlet 111.
[0085] As the sun's altitude angle increases from morning onwards, the incident angle of sunlight hitting the heat-reflecting component 23 decreases accordingly. The incident angle of sunlight gradually approaches the vertical heat dissipation glass 11, thus heating the heat dissipation glass 11. During the heating process, the expansion member 223 expands due to heat, pushing the rack 222. The rack 222 drives the gear 2331 to rotate, which in turn drives the first fixing member 233 to rotate. The reflector 232 in the first fixing member 233 also rotates, causing the reflector 232 to automatically deflect with the rotation of the sun, so as to fully reflect the sunlight onto the receiver 231. The ventilation duct 2312 of the receiver 231 releases heat into the heat insulation space 4, causing the gas in the heat insulation space 4 to expand rapidly due to heat. The fan 13 located at the top of the heat insulation space 4 blows the hot air towards the bottom of the heat insulation space 4, so that the hot air flows to the outside through the air outlet 112 on the heat dissipation glass 11, thereby achieving the heat insulation effect. Compared to the poor signal reception of traditional insulated glass 12, this application utilizes the cooperation between the heat-reflecting component 23 and the rotating component 22 to block sunlight, thus eliminating the need to spray a magnetic metal layer onto the glass surface to block infrared rays from sunlight. Therefore, the influence of the insulated window sash on the electrical signal is minimal. Secondly, due to the cooperation between the fan 13 and the receiver 231, the high-temperature airflow within the insulated space cannot exchange heat with the insulated glass 12 in a timely manner. The heat transfer coefficient of this insulated window sash is 2.2–2.5 W / (m²·K), effectively blocking sunlight from the outside and preventing indoor temperature from rising.
[0086] Water-blocking components can be installed at the air inlet 111 and the air outlet 112 respectively. The water-blocking components include an upper water-blocking plate and a lower water-blocking plate. The lower water-blocking plate can rotate relative to the upper water-blocking plate. When the lower water-blocking plate rotates toward the upper water-blocking plate, it can block the air inlet 111 or the air outlet 112. The water-blocking components can effectively prevent raindrops from entering the heat insulation space 4 through the air inlet 111 and the air outlet 112 during rainy days.
