DETAILED DESCRIPTION

[0045] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the embodiments of the present application. It is known to those skilled in the art that with the development of technology and the emergence of new scenarios, the technical solutions provided in the embodiments of the present application are also applicable to similar technical problems.

[0046] Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present application. The terms used in the embodiments of the present application are only used to explain the specific embodiments of the present application, and are not intended to limit the present application.

[0047] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0048] refer to Figure 1 , Figure 1 A cross-sectional view of a functional glass for a building provided in an embodiment of the present application, wherein the functional glass includes:

[0049] A first glass plate 11 and a second glass plate 12 are arranged opposite to each other, and a receiving cavity 13 is provided between the first glass plate 11 and the second glass plate 12; the first glass plate 11 is used to be arranged facing indoors of a building; and the second glass plate 12 is used to be arranged facing outdoors of the building;

[0050] Thermoelectric assembly 14, the thermoelectric assembly 14 has a first side and a second side opposite to each other, the first side is fixed on a surface of the first glass plate 11 facing the second glass plate 12;

[0051] The thermoelectric component 14 can form a temperature difference between the first side and the second side based on an input working current.

[0052] In the functional glass provided in the embodiment of the present application, a thermoelectric component 14 is arranged in the accommodating cavity 13 formed by the first glass plate 11 and the second glass plate 12. The thermoelectric component 14 can form a temperature difference between the first side and the second side based on the input working current. Based on the temperature difference, the functional glass can control the indoor temperature facing the first glass plate 11, thereby realizing active regulation of the indoor temperature of the building.

[0053] like Figure 1 As shown, the first glass plate 11 and the second glass plate 12 can be bonded and fixed at the edges thereof by means of fixing members 15 .

[0054] In the embodiment of the present application, the functional glass realizes regulation of the temperature difference between the first side and the second side thereof based on the Peltier effect of the thermoelectric component.

[0055] Specifically, the thermoelectric component 14 includes a PN semiconductor thermoelectric element. The PN semiconductor thermoelectric element has a Peltier effect. When current passes through the PN semiconductor thermoelectric element composed of two different semiconductors, heat absorption and heat release phenomena will occur on both sides of the PN semiconductor thermoelectric element. Specifically, when current flows from a P-type semiconductor to an N-type semiconductor, electrons recombine between the PN junction regions, releasing energy, while also dissipating heat, causing the N-type semiconductor to become cold. On the contrary, when current flows from an N-type semiconductor to a P-type semiconductor, electrons will also recombine between the PN junction regions, but at this time, since the energy direction is opposite, heat will be absorbed, causing the P-type semiconductor region to become hot.

[0056] Based on the above description, it can be known that in the functional glass provided in the embodiment of the present application, by controlling the direction of the working current flowing through the thermoelectric component 14, the relative temperature of the thermoelectric component 14 on the first side and the second side can be regulated, so that the functional glass has an indoor heating mode and an indoor cooling mode.

[0057] If in the indoor heating mode, the thermoelectric component 14 is connected to the first working current, and the temperature of the first side is greater than the temperature of the second side; if in the indoor cooling mode, the thermoelectric component 14 is connected to the second working current, and the temperature of the first side is lower than the temperature of the second side; wherein the first working current and the second working current are transmitted in opposite directions in the thermoelectric component 14.

[0058] The functional glass provided in the embodiment of the present application can select whether the functional glass is in indoor heating mode or indoor cooling mode by controlling the direction of the working current in the thermoelectric component 14, so as to adjust the indoor temperature through the functional glass based on usage needs.

[0059] In the indoor cooling mode, the temperature of the first side is lower than the temperature of the second side. Since the first side of the thermoelectric assembly 14 is directly fixed on the surface of the first glass plate 11, the low temperature of the first side can directly reduce the indoor temperature by heat conduction. At this time, the high temperature of the second side can be dissipated to the external environment through the second glass plate 12.

[0060] As modern buildings have higher requirements for energy saving and comfort, the shortcomings of traditional air-conditioning systems in terms of high energy consumption and maintenance complexity are becoming increasingly prominent. The functional glass provided in the embodiment of the present application is provided with a thermoelectric component 14. In the indoor cooling mode, efficient and flexible indoor cooling can be achieved through thermoelectric cooling technology, which has broad application prospects in the field of energy saving.

[0061] In the indoor heating mode, the temperature of the first side is greater than the temperature of the second side. Since the first side of the thermoelectric component 14 is directly fixed on the surface of the first glass plate 11, the low temperature of the first side can directly heat conduction to increase the indoor temperature. At this time, the low temperature of the second side can exchange temperature with the external environment through the second glass plate 12.

[0062] The functional glass provided in the embodiment of the present application can actively adjust the indoor temperature based on the use requirements. When the indoor temperature is low, it is in the indoor heating mode to actively heat the indoor temperature, and when the indoor temperature is high, it is in the indoor cooling mode to actively cool the indoor temperature.

[0063] The functional glass may be a flat glass plate or a three-dimensional curved plate of a special shape. The plate graphic structure of the functional glass may be designed according to the structure of the building. The embodiment of the present application does not limit the plate structure of the functional glass.

[0064] In one implementation of the embodiment of the present application, it can be as follows Figure 2 As shown, the thickness of the thermoelectric component 14 is set to be smaller than the thickness of the accommodating cavity 13 .

[0065] refer to Figure 2 , Figure 2 A cross-sectional view of another functional glass for buildings provided in an embodiment of the present application, based on the above-mentioned implementation mode, a heat-conducting component 16 is provided between the thermoelectric component 14 and the second glass plate 12; the heat-conducting component 16 is used to improve the heat conduction efficiency between the second side of the thermoelectric component 14 and the second glass plate 12, thereby improving the heat exchange efficiency between the second side of the thermoelectric component 14 and the external environment.

[0066] When the functional glass is in indoor cooling mode, the first side of the thermoelectric component 14 is the low-temperature side, and the second side is the high-temperature side. Based on the heat-conducting component 16, the heat on the second side can be quickly transferred to the second glass plate 12 and dissipated to the external environment through the second glass plate 12 to ensure the cooling effect and the efficient operation of the cooling function.

[0067] When the functional glass is in indoor heating mode, the first side of the thermoelectric component 14 is the high temperature side, and the second side is the low temperature side. Based on the heat conducting component 16, the second glass plate 12 can quickly conduct the external environment heat to the second side of the thermoelectric component 14 to ensure the heating effect and the efficient operation of the heating function.

[0068] In one implementation of the embodiment of the present application, the heat-conducting component 16 can be a light-transmitting heat-conducting adhesive layer, which can achieve a good heat-conducting effect while avoiding blocking the incident light to ensure the light-transmitting performance of the functional glass. The heat-conducting adhesive layer can be a heat-conducting silicone grease coated on the upper surface of the thermoelectric component 14, or a heat-conducting silicone grease sheet attached to the upper surface of the thermoelectric component 14.

[0069] refer to Figure 3-Figure 5 , Figure 3 A three-dimensional perspective view of a functional glass provided in an embodiment of the present application. Figure 4 for Figure 3 A top view of the functional glass shown, Figure 5 for Figure 3 In order to clearly illustrate the layout of the heat conducting component 16, Figure 4 The second glass plate 12 is not shown in the figure. Based on the above embodiment, Figure 3-Figure 5 In the functional glass shown, the heat-conducting component 16 is a water-cooling tube disposed on the second side of the thermoelectric component 14 .

[0070] Optionally, in order to improve the thermal contact effect, the water cooling tube is fixed to the surface of the thermoelectric component 14 by bonding with thermal conductive silicone grease.

[0071] Figure 3-Figure 5 In the functional glass shown, in cooling mode, since the second side is the high temperature side, the circulating cooling water in the water cooling tube can quickly take away the heat on the second side, thereby increasing the heat dissipation rate on the second side. In heating mode, the second side is the low temperature side, and the heat can be spontaneously transferred to the external environment through the second glass plate 12 based on heat conduction, and the circulating water in the cooling tube can be turned off.

[0072] refer to Figure 6 and Figure 7 , Figure 6 A cross-sectional view of another functional glass for a building provided in an embodiment of the present application, Figure 7 for Figure 6 In order to clearly illustrate the layout of the heat conducting component 16, Figure 7 The second glass plate 12 is not shown in the figure. Based on the above embodiment, Figure 6 and Figure 7 In the functional glass shown, the heat conducting component 16 is a heat dissipation fin disposed on the second side of the thermoelectric component 14. In order to increase the heat exchange speed, a fan 17 is further disposed between the first glass plate 11 and the second glass plate 12.

[0073] Optionally, in order to improve the thermal contact effect, the heat sink fins are fixed to the surface of the thermoelectric component 14 by bonding with thermal conductive silicone grease.

[0074] Figure 6 and Figure 7In the functional glass shown, in the cooling mode, since the second side is the high temperature side, the heat on the second side of the thermoelectric assembly 14 can be quickly transferred to the heat dissipation fins, the heat dissipation area is increased by the heat dissipation fins, and the heat is quickly dissipated to the outside by the fan 17. In order to dissipate the heat quickly, in this method, an exhaust hole connected to the indoor environment can be provided on the second glass plate 12 or the fixing member 15.

[0075] In one implementation of the present application, the thermoelectric assembly 14 may be a light-transmitting thermoelectric film, which can actively control the indoor temperature through the thermoelectric assembly 14 and also provide the thermoelectric assembly 14 with a good light-transmitting effect to prevent the thermoelectric assembly 14 from blocking light. The light-transmitting thermoelectric film may be cuprous oxide glass.

[0076] As mentioned above, the thermoelectric assembly 14 may also include a PN semiconductor thermoelectric element. Since the light transmittance of the thermoelectric pair of semiconductor materials is poor, in order to ensure the light transmittance of the functional glass, in one embodiment of the present application, the functional glass may be provided with a plurality of light-transmitting areas and light-impermeable areas arranged alternately; the thermoelectric assembly 14 is located in the light-impermeable area. If the functional glass has a heat-conducting assembly 16, the heat-conducting assembly 16 is located on the second side surface of the thermoelectric assembly 14, and will not block the light-transmitting area.

[0077] refer to Figure 8 , Figure 8 A schematic diagram of the layout of a thermoelectric component in a functional glass provided in an embodiment of the present application, Figure 8 FIG. 1 is a top view of the layout of the thermoelectric components 14 on the first glass plate 11. In order to clearly illustrate the layout of the thermoelectric components 14 on the surface of the first glass plate 11, Figure 8 The second glass plate 12 is not shown. Based on the above embodiment, Figure 8 In the functional glass shown, the thermoelectric assembly 14 includes: a plurality of thermoelectric modules 141 arranged on the surface of the first glass plate 11; the plurality of thermoelectric modules 141 are arranged at intervals along a first direction Y, and a first light-transmitting gap 142 is provided between adjacent thermoelectric modules 141; the first direction Y is parallel to the plane where the first glass plate 11 is located.

[0078] Figure 8 In the functional glass shown, the thermoelectric component 14 includes a plurality of thermoelectric modules 141 spaced apart in a first direction Y, so that the functional glass has a plurality of light-transmitting areas and light-impermeable areas spaced apart, and each light-impermeable area corresponds to a thermoelectric module 141. The first gap 142 between adjacent thermoelectric modules 141 can be used as a light-transmitting area, so that the functional glass has the light-transmitting effect of a blind.

[0079] exist Figure 8In the illustrated embodiment, if the functional glass has a heat conducting component 16 , the heat conducting component 16 is located on the second side surface of the thermoelectric module 141 , and the heat conducting component 16 does not overlap with the first gap 142 , thus not blocking the light-transmitting area.

[0080] Optionally, the thermoelectric module 141 includes a plurality of P-type semiconductor blocks and N-type semiconductor blocks alternately arranged along the second direction X, and adjacent P-type semiconductor blocks and N-type semiconductor blocks form PN semiconductor thermoelectric elements 143; the PN semiconductor thermoelectric elements 143 in the same thermoelectric module 141 are sequentially connected in series; wherein the second direction X is parallel to the plane where the first glass plate 11 is located, and is perpendicular to the first direction Y. The thermoelectric module 141 is provided to include a plurality of PN semiconductor thermoelectric elements 143 sequentially connected in series, which can improve the cooling and heating effects of the thermoelectric assembly 14.

[0081] refer to Fig. 9 , Fig. 9 A cross-sectional view of another functional glass provided in an embodiment of the present application, Figure 8 Based on the method shown, Fig. 9 In the functional glass shown, the first gap 142 is filled with a light-transmitting material 18, and the light-transmitting material 18 also covers at least a portion of the thermoelectric module 141 on the second side, so that the outdoor light irradiating the thermoelectric module 141 can pass through the first gap 142 based on the light-guiding effect of the light-transmitting material 18, so that the light passing through the first gap 142 can irradiate the room. In this way, the shielding of the incident light by the opaque thermoelectric module 141 can be reduced.

[0082] Based on the above implementation method, Fig. 9 As shown, the surface of the light-transmitting material 18 facing away from the first glass plate 11 may include a convex structure. Based on the light-collecting effect of the convex structure, the outdoor light irradiating the thermoelectric module 141 can pass through the first gap 142 and irradiate into the room.

[0083] Optionally, the light-transmitting material 18 may be arranged to contact the second glass plate 12. At this time, in order to reduce the total reflection of the incident light at the interface between the light-transmitting material 18 and the second glass plate 12, the refractive index of the light-transmitting material 18 is arranged to be greater than the refractive index of the second glass plate 12.

[0084] When the refractive index of the light-transmitting material 18 is greater than the refractive index of the second glass plate 12, the second glass plate 12 is a light-sparse medium and the light-transmitting material 18 is a light-dense medium. When external ambient light is incident from the second glass plate 12 toward the light-transmitting material 18, the light is incident from the light-sparse medium to the light-dense medium, which can prevent the light from being totally reflected at the interface between the light-transmitting material 18 and the second glass plate 12, thereby increasing the proportion of external ambient light incident into the room to increase the brightness of the indoor ambient light.

[0085] In the embodiment of the present application, the height of the accommodating cavity 13 is set to be greater than the thickness of the thermoelectric module 141. At this time, the light-transmitting material 18 may not be in contact with the second glass plate 12; Fig. 9 As shown, the light-transmitting material 18 may be disposed in contact with the second glass plate 12 .

[0086] In other embodiments, the height of the accommodating cavity 13 is also set to be equal to the thickness of the thermoelectric module 141 . At this time, if the light-transmitting material 18 is provided, the thickness of the light-transmitting material 18 may be equal to or less than the thickness of the thermoelectric module 141 .

[0087] If the thickness of the light-transmitting material 18 is equal to or less than the thickness of the thermoelectric module 141 , although the light irradiating the thermoelectric module 141 cannot pass through the first gap 142 , the light-transmitting material 18 can still adjust the propagation path of the light irradiating the first gap 142 to adjust the irradiation range of the external ambient light to the room.

[0088] In the embodiment of the present application, if the thermoelectric assembly 14 includes a plurality of thermoelectric modules 141 arranged at intervals, a light-transmitting material 18 may be filled in the first gap 142, and the light-transmitting material 18 is at least used to adjust the propagation path of the light irradiating the first gap 142, so as to adjust the irradiation range of the external ambient light to the room. Furthermore, the light-transmitting material 18 may be arranged to cover at least part of the thermoelectric module 141 on the second side, so that the outdoor light irradiating the thermoelectric module 141 can pass through the first gap 142 based on the light-guiding effect of the light-transmitting material 18.

[0089] When the light-transmitting material 18 is disposed in the first gap 142, fluorescent powder may also be mixed in the light-transmitting material 18. In this way, the functional glass can absorb ambient light through the fluorescent powder during the day and release fluorescent light at night to enhance the night appearance effect.

[0090] refer to Fig.10 , Fig.10 This is an equivalent circuit diagram of a thermoelectric module provided in an embodiment of the present application. Based on the above implementation, Fig.10 In the illustrated embodiment, the thermoelectric module 141 includes a plurality of PN semiconductor thermoelectric elements 143 connected in series. The PN semiconductor thermoelectric elements 143 include a P-type semiconductor and an N-type semiconductor.

[0091] like Fig.10As shown, in the same PN semiconductor thermoelectric element 143, on the second side of the thermoelectric component 14, the P-type semiconductor and the N-type semiconductor are connected through the first conductive layer 144; in two adjacent PN semiconductor thermoelectric elements 143, on the first side of the thermoelectric component 14, the N-type semiconductor of one PN semiconductor thermoelectric element 143 is connected to the P-type semiconductor of the other PN semiconductor thermoelectric element 143 through the second conductive layer 145; the two ends of a plurality of PN semiconductor thermoelectric elements 143 connected in series are connected to a working voltage V, and by controlling the polarity of the voltage connected to the two ends, the flow direction of the current in the adjacent P-type semiconductors and N-type semiconductors can be controlled, thereby controlling the temperature of the first side to be greater than the temperature of the second side, or controlling the temperature of the first side to be less than the temperature of the second side.

[0092] In order to ensure the light transmission effect of the functional glass, the first conductive layer 144 and the second conductive layer 145 are both transparent conductive layers to prevent the conductive layers from blocking light. The first conductive layer 144 and the second conductive layer 145 can be made of indium tin oxide (ITO) or silver nanowires.

[0093] In the functional glass provided in the embodiment of the present application, the accommodating cavity 13 may be a sealed cavity. In this case, in order to improve the heat insulation and sound insulation effect of the functional glass, the accommodating cavity 13 may be filled with an inert gas, such as argon, etc. In other embodiments, in order to facilitate the temperature interaction between the gas in the accommodating cavity 13 and the external environment gas, the accommodating cavity 13 may also be provided with an exhaust hole connected to the external environment.

[0094] In the embodiment of the present application, if filled with a light-transmitting material 18, the light-transmitting material 18 can partially fill the accommodating cavity 13 and leave a gas space in the accommodating cavity, or the light-transmitting material 18 can completely fill the accommodating cavity 13 where the thermoelectric component 14 is arranged.

[0095] Optionally, in order to improve the weather resistance of the functional glass, a protective layer may be provided on the functional outer side, and the protective layer may cover the outer surface of the glass plate or the side wall of the functional glass to ensure the safe and reliable operation of the functional glass and increase its service life.

[0096] Based on the above embodiments, another embodiment of the present application further provides a preparation method for preparing the functional glass provided by any one of the above embodiments. The preparation method can be as follows: Fig.11 shown.

[0097] refer to Fig.11 , Fig.11 A schematic diagram of a method for preparing functional glass provided in an embodiment of the present application, combined with Fig.11 As shown in the above-mentioned embodiment drawings, the preparation method comprises:
