Description

Technical Field

[0001] This invention relates to the field of building engineering technology, and in particular to a curtain wall unit and a curtain wall. Background Technology

[0002] Currently, with people's increasing demands for living environments and the growing urgency of energy shortages and environmental pollution, and against the backdrop of promoting low-carbon and environmentally friendly practices, energy conservation in buildings, as a major energy consumer, is gradually gaining attention, and awareness of building energy conservation and environmental protection is constantly increasing. Examples include the integration of photovoltaic glass panels and exterior wall sunshades into building facades, with sunshades being the most common application.

[0003] Typically, curtain wall sunshades are installed perpendicular to the finished curtain wall surface. However, in unitized curtain wall systems, for ease of transport, the sunshade structure and curtain wall units are often transported separately and then assembled on-site for integrated hoisting. Furthermore, if it's a photovoltaic sunshade structure, on-site wiring integration is also required. This undoubtedly increases the number of procedures, transportation, and management costs. In addition, the complexity of the construction site introduces numerous uncertainties, increasing project risk and costs, and negatively impacting indoor lighting. In existing curtain wall systems, without additional sunshade structures, sunlight directly enters the interior, leading to high indoor temperatures. This necessitates additional cooling equipment for residents, further increasing costs.

[0004] In view of the shortcomings of existing curtain wall systems, those skilled in the art have been searching for solutions. Summary of the Invention

[0051] Furthermore, while each embodiment described below possesses one or more technical features, this does not imply that users of the present invention must simultaneously implement all technical features in any embodiment, or can only separately implement some or all technical features in different embodiments. In other words, provided it is feasible, those skilled in the art can, based on the disclosure of the present invention and depending on design specifications or implementation requirements, selectively implement some or all technical features in any embodiment, or selectively implement a combination of some or all technical features in multiple embodiments, thereby increasing the flexibility in implementing the present invention.

[0052] To make the objectives and features of the present invention more apparent and understandable, the specific embodiments of the present invention will be further described below with reference to the accompanying drawings. However, the present invention can be implemented in different forms and should not be considered as being limited to the embodiments described.

[0053] Please refer to Figure 9 This is a schematic diagram of the curtain wall structure in one embodiment of the present invention. Figure 9As shown, multiple curtain wall units 100 are arranged and connected in a matrix to form a complete curtain wall, which is installed on the exterior wall of a building. It can be understood that the size specifications of the curtain wall units 100 can adopt various specifications according to the actual situation, such as 1m * 1m, 2m * 1m, etc.

[0054] As is well known, the climate in China is worse than that in other regions at the same latitude in the world. It is hotter in summer and colder in winter than other regions at the same latitude, and the climate in the hot summer and cold winter regions in China is even more extreme. Taking the eastern coastal area as an example, the weather is very hot in summer. In cities, for the curtain walls of high-rise buildings, in order to meet the requirements of light transmission and daylighting, it is often necessary to set up sunshade curtains in the office to avoid the increase of indoor temperature caused by the heat radiation of sunlight. For the curtain wall unit 100 of the present application, by setting a cooling structure in the cooling cavity of the insulating curtain wall glass, the cooling and heat insulation effects are achieved starting from the structure of the curtain wall itself. The following will elaborate on the curtain wall unit 100 designed by the present invention.

[0055] Please refer to Figure 1 and Figure 2 , Figure 1 is a schematic structural diagram of a curtain wall unit in an embodiment of the present invention; Figure 2 is a schematic cross-sectional structural diagram of a curtain wall unit in an embodiment of the present invention. As Figure 1 and Figure 2 shown, the curtain wall unit includes: a fixed framework, four insulating curtain wall glasses 40, and several cooling structures 50; wherein, each insulating curtain wall glass has a cooling cavity A provided therein, and at least one cooling structure 50 is provided in the cooling cavity A; the four insulating curtain wall glasses are arranged at intervals in a square matrix; the fixed framework is arranged at the middle position of the square matrix to fixedly connect the four insulating curtain wall glasses 40 into one body. Among them, the fixed framework includes a fixed horizontal frame body 10, an outer fixed vertical frame body 20, and an inner fixed vertical frame body 30. The middle position of the square matrix includes an X gap and a Y gap. The outer fixed vertical frame body 20 and the inner fixed vertical frame body 30 are assembled and clamped with each other and are arranged in the Y gap to clamp and fix the sides of the four insulating curtain wall glasses 40 adjacent to the Y gap; the fixed horizontal frame body 10 is arranged in the X gap and is fixedly connected to the outer fixed vertical frame body 20 and / or the inner fixed vertical frame body 30 to fix the sides of the four insulating curtain wall glasses 40 adjacent to the X gap. The four insulating curtain wall glasses 40 are arranged at intervals and distributed in a matrix. For example, the four insulating curtain wall glasses 40 are arranged in a square (such as a "field" - shaped structure), and the distance between two adjacent insulating curtain wall glasses 40 is the same. Two gaps can be set at the middle position of the matrix formed by the four insulating curtain wall glasses 40: the X gap (horizontal) and the Y gap (vertical). These two gaps are the reserved spaces for setting the corresponding fixed frameworks (the fixed horizontal frame body 10, the outer fixed vertical frame body 20, and the inner fixed vertical frame body 30).

[0056] Specifically, by adding a cooling structure 50 to the curtain unit itself, when sunlight shines on the curtain wall, the resulting heat radiation is conducted to the cooling structure 50. The cooling structure 50 isolates the solar heat radiation within the multi-specification curtain wall units 100, preventing heat radiation from being conducted into the room. Since there is no need to install additional shading devices, it is beneficial for sunlight to enter the room, ensuring indoor lighting effects. This solves the technical problems of complex construction sites and many uncertainties when installing curtain wall sunshades on the curtain wall, which to some extent increases the project risk and is more costly, and is not conducive to indoor lighting.

[0057] It is understandable that the cooling structure 50 includes, but is not limited to, coolant, heat dissipation fins, and refrigerant pipes. The coolant can be housed within a hollow cavity, combined with a metal structure as the primary heat dissipation component. The refrigerant pipes are primarily designed with future smart home systems in mind, integrating air conditioning refrigerant into the curtain wall to achieve intelligent indoor temperature control. Further details will not be elaborated upon here.

[0058] Of course, shading devices can also be installed indoors. Although shading devices also absorb the heat from sunlight, the indoor temperature can still be reduced through cooling structures, which is a double cooling measure.

[0059] Please refer to Figure 4 This is a schematic diagram of another cross-sectional structure of a curtain wall unit in one embodiment of the present invention; as shown below. Figure 4 As shown, the hollow curtain wall glass 40 has an air inlet B and an air outlet C that communicate with the cooling cavity A. Along the length of the outer fixed vertical frame 20, the cooling structure 50 is disposed on the hollow curtain wall glass 40 between the air inlet B and the air outlet C (e.g., Figure 4 As shown, in this embodiment, all the cooling structures 50 are installed on the wall of the indoor glass 42, so that gas enters the cooling cavity A from the air inlet B, flows through all the cooling structures 50, and is discharged from the air outlet C.

[0060] In this embodiment, the main problem of "summer heat" is solar radiation (composed of direct sunlight, diffused sunlight, and environmental reflection), with the heat gained from direct sunlight far exceeding that from diffused sunlight. Traditional glass curtain walls are mostly single-pane glass and lack cooling structures. Therefore, relying on the light transmission properties of glass, visible solar radiation enters the room, and although indoor shading reflects some direct sunlight, the heat absorbed and reflected by these devices forms thermal radiation that cannot penetrate the glass, resulting in excessive indoor heat.

[0061] This invention designs the curtain wall as a double-glazed structure, thus forming a cooling cavity A as the supporting space for the cooling structure 50 that lowers the indoor temperature. Furthermore, by creating air inlets B and outlets C on the insulated curtain wall glass 40 that communicate with the cooling cavity A, and placing the cooling structure 50 between the air inlets B and outlets C, a double-glazed curtain wall glass 40 with a "breathing" function is formed. When the indoor temperature rises, the gas temperature inside the cooling cavity A is lower than the indoor gas temperature. At this time, the high-temperature indoor gas enters through the air inlet B, flows through the cooling structure 50, and finally flows out through the outlet C, achieving a heat exchange and cooling effect.

[0062] Understandably, the specific locations of the air inlet B and outlet C on the insulated glass 40 can be either on the same pane of glass or on different panes. When they are on different panes, the air inlet B and outlet C are diagonally positioned, creating a diagonal airflow and increasing indoor heat loss. By employing a structure consisting of the insulated glass 40 and the cooling structure 50, and further adding the air inlet B and outlet C to the insulated glass 40, convective heat transfer can be increased, minimizing the amount of conductive heat input from the outside and effectively reducing the indoor temperature.

[0063] Please continue to refer to this. Figure 1 The hollow curtain wall glass 40 includes: an exterior glass 41 and an interior glass 42, wherein the exterior glass 41 and the interior glass 42 are spaced apart and together form a cooling cavity A (e.g., Figure 1 As shown, the outdoor glass 41 and the indoor glass 42 are parallel to each other and spaced a certain distance apart. The intermediate layer between the double-glazed windows and the double-glazed windows constitute a cooling cavity A. The cooling structure is disposed on the outdoor glass 41 or the indoor glass 42. The outdoor glass 41 or the indoor glass 42 has an air inlet B and an air outlet C. In this embodiment, the cooling structure is disposed on the indoor glass 42.

[0064] Typically, the outer curtain wall uses a single-layer or laminated glass structure with an air gap in between, ranging in thickness from 300mm to 2000mm. The inner curtain wall generally uses double-layer insulated glass 40. One of the most important performance indicators for glass curtain walls is thermal insulation. Heat transfer occurs in three ways: conduction, convection, and radiation. This application uses a structure consisting of insulated glass 40 and a cooling structure 50, which minimizes the amount of heat transferred from the outside. The cooling cavity A within the double-layer insulated glass 40 also increases convective heat transfer, effectively reducing the indoor temperature when combined with the cooling structure 50.

[0065] In this embodiment, in order to minimize the indoor temperature, the cooling structure 50 can be installed on the indoor glass 42. In addition to cooling the airflow in the cooling cavity A, the cooling structure 50 also conducts indoor heat radiation to the indoor glass 42 and directly to the cooling structure 50 for cooling.

[0066] Please refer to Figure 6 This is a schematic diagram of the cross-sectional structure of a curtain wall unit in another embodiment of the present invention. Figure 6 As shown, the indoor glass 42 is provided with the air inlet B, and the outdoor glass 41 is provided with the air outlet C.

[0067] Understandably, the positions of the air inlet B and the air outlet C, except... Figure 6 In addition to the example shown, in order to facilitate effective natural wind heat dissipation, an air inlet B can be provided on the outdoor glass 41 and an air outlet C can be provided on the indoor glass 42, so that the air inlet B and the air outlet C form an oblique airflow, thereby increasing the heat loss indoors.

[0068] Please refer to Figure 8 This is a schematic diagram of the cooling structure of a curtain wall unit in one embodiment of the present invention. Figure 8 As shown, the cooling structure 50 used in this embodiment includes: a support 51, a heat sink 52, and heat dissipation fins 53. The support 51 is disposed on the inner wall of the cooling cavity (specifically, the support 51 can be glued to the inner wall of the cooling cavity A); the heat sink 52 is disposed on the support 51; the heat dissipation fins 53 are disposed on the surface of the heat sink 52, and the heat dissipation fins 53 are bent towards the air inlet B to collide with the airflow entering the cooling cavity A from the air inlet B. Preferably, the cooling structure 50 can be made entirely of aluminum material; the heat dissipation fins 53 have an arc-shaped structure to enhance the collision with the airflow in the cooling cavity A.

[0069] In this embodiment, the cooling structure 50 can employ mechanical cooling. For example, the support 51 of the cooling structure 50 has a hollow structure, increasing the contact area with the gas without affecting the airflow velocity inside the cooling cavity A. Furthermore, the heat sink 52 is mounted on the support 51, with its heat dissipation fins 53 facing the air inlet B. Thus, after high-temperature gas enters through the air inlet B, it circulates towards the air outlet C. During this process, the high-temperature gas primarily collides with the heat sink 52 and the arc-shaped heat dissipation fins 53. The heat in the gas is absorbed by the heat sink 52 and the heat dissipation fins 53. Due to the shape of the heat dissipation fins 53, after colliding with them, the gas will bounce back along the curved surface of the fins 53 towards the air inlet B, increasing the frequency of gas colliding with the same heat dissipation fin 53 and improving the cooling effect.

[0070] Please refer to Figure 1 , Figure 2 and Figure 3 , Figure 3 yes Figure 2 A magnified view of a section at point K. (See image below.) Figure 1 As shown, the curtain wall unit further includes: a first decorative frame 71 and a second decorative frame 72, wherein the first decorative frame 71 is disposed on the fixed horizontal frame 10, and the second decorative frame 72 is disposed on the outer fixed vertical frame 20 or the inner fixed vertical frame 30.

[0071] Among them, such as Figure 3 As shown, the inner fixed vertical frame 30 includes: a first body and two hooks 31, the two hooks 31 being respectively disposed at both ends of the first body along its length; wherein, each hook 31 includes: a first hook segment 311 and a second hook segment 312 connected together, the first hook segment and the second hook segment forming a "3" shape, and a hook groove H being formed at the connection position of the first hook segment 311 and the second hook segment 312. The second decorative frame 72 includes: a second frame and two locking protrusions 721, the two locking protrusions 721 being respectively disposed at both ends of the second frame, the locking protrusions 721 engaging with the hook grooves H, so that the second decorative frame 72 is installed on the inner fixed vertical frame 30. Preferably, the second decorative frame 72 has a "U" shaped structure.

[0072] To facilitate understanding, a detailed explanation will be given using the example of the second decorative frame 72 being installed in the inner fixed vertical frame 30. For example... Figure 3 As shown, a hook 31 is provided horizontally on the inner fixed vertical frame 30. The hook 31 has a first hook segment 311 and a second hook segment 312 in the shape of the number "3". The connection position between the first hook segment 311 and the second hook segment 312 forms a hook groove H. Correspondingly, a "U"-shaped structure is provided on the second decorative frame 72. A locking protrusion 721 is provided inside the "U"-shaped structure. When the second decorative frame 72 is installed, the hook 31 is placed inside the "U"-shaped structure, and the locking protrusion 721 abuts against the corresponding hook groove H to form a locking structure, so that the second decorative frame 72 is stably fixed on the inner fixed vertical frame 30.

[0073] Please refer to Figure 1 , Figure 5 and Figure 7 , Figure 5 yes Figure 4 A magnified view of a portion of point M in the middle; Figure 7 yes Figure 6 A magnified view of a portion of point N in the diagram; Figure 4 and Figure 6 In fact, it is based on Figure 1 The diagram shows the cross-section in the same direction. To better illustrate the positions of N and M in the diagram, two separate diagrams are presented. For example... Figure 1 and Figure 5 As shown, the curtain wall unit further includes a waterproof component 60 and a screw 80. The waterproof component 60 is disposed between the first decorative frame 71 and the fixed horizontal frame 10. The screw 80 passes through the threads on the first decorative frame 71, the waterproof component 60 and the fixed horizontal frame 10 in sequence to make the first decorative frame 71 and the waterproof component 60 fixed on the fixed horizontal frame 10.

[0074] Specifically, such as Figure 5 and Figure 7 As shown, the first decorative frame 71 includes: a first frame body, a hook 711 disposed at the bottom of the first frame body, and two first slots E formed on the first frame body, each first slot E having a contact surface G4; as Figure 7 As shown, the waterproof component 60 includes: a second body and two protrusions 61 and several protrusions 62 respectively disposed on two opposite surfaces along the length of the second body; wherein, several protrusions 62 are disposed on the first surface of the second body; the two protrusions 61 are respectively disposed at both ends of the first surface of the second body; the first surface faces the first decorative frame 71, and the second surface faces the fixed horizontal frame 10; each protrusion 61 has a first inclined surface G1, a second inclined surface G2, and two third inclined surfaces G3 (in this example, the first inclined surface G1 is a first inclined surface G2, the second inclined surface G2, and the third inclined surface G3). Both the first inclined surface G1 and the second inclined surface G2 have a third inclined surface G3 on the side facing the fixed horizontal frame 10. The first inclined surface G1 intersects with the second inclined surface G2 to form a spike structure. The first inclined surface G1 intersects with the corresponding third inclined surface G3 to form an acute angle, and the second inclined surface G2 intersects with the corresponding third inclined surface G3 to form an acute angle. Both third inclined surfaces G3 are connected to the second body. Each protrusion 61 is correspondingly disposed in a first slot E. The third inclined surface G3 abuts against the snap-fit ​​surface G4 to connect the waterproof component 60 to the first decorative frame 71. Preferably, in the direction perpendicular to the length of the second body, the center of the protrusion 61 is provided with a deformation groove F, so that the protrusion 61 will squeeze the groove wall of the deformation groove F when subjected to external force, so that the protrusion 61 will deform and be disposed in the first slot E.

[0075] Specifically, in this embodiment, the cross-sectional shape of each protrusion 61 is rhomboid. When the protrusion 61 is engaged in the first slot E, its first inclined surface G1 and second inclined surface G2 abut against the bottom of the first slot E and deform. Since the first inclined surface G1 and the third inclined surface G3 form an acute angle, the side of the protrusion 61 facing the fixed horizontal frame 10 has a protruding point structure. This protruding point structure can abut against the engaging surface G4 of the first slot E, so that the protrusion 61 cannot detach from the first slot E; similarly, the process is the same for the second inclined surface G2. When the first decorative frame 71 is subjected to force, the third inclined surface G3 always abuts against the engaging surface G4 and locks the protrusion 61 in the first slot E. In addition, in order to improve the waterproof effect of the waterproof component 60, a plurality of protrusions 62 are provided on the surface of the waterproof component 60 facing the fixed horizontal frame 10. When the waterproof component 60 is subjected to the squeezing force of the first decorative frame 71 and the fixed horizontal frame 10, the structure of the protrusions 62 deforms and fills the tiny gap between the waterproof component 60 and the surface of the fixed horizontal frame 10, preventing external moisture from seeping into the interior of the fixed horizontal frame 10.

[0076] In this embodiment, the curtain wall unit 100 also needs to be fitted with decorative materials. To facilitate the fixed installation of the decorative materials (i.e., the first decorative frame 71 and the second decorative frame 72), such as... Figure 5 As shown, taking the first decorative frame 71 as an example, a mounting cavity D is provided on the side of the fixed horizontal frame 10 away from the hollow curtain wall glass 40. The mounting cavity D has an opening, and correspondingly, a first slot E and a hook 711 are provided on the first decorative frame 71. When the first decorative frame 71 is installed on the fixed horizontal frame 10, the hook 711 is disposed in the mounting cavity D and abuts against the cavity wall of the mounting cavity D at the upper end of the opening.

[0077] To facilitate understanding, the following explanation will focus on the combination of the waterproof component 60 and the first decorative frame 71. For example... Figure 7 As shown, the waterproof component 60 is first installed on the first decorative frame 71. Specifically, the protrusion 61 of the waterproof component 60 is positioned on the first slot E of the first decorative frame 71. The size of the protrusion 61 can be slightly larger than the size of the first slot E, so that after the protrusion 61 is engaged with the first slot E, the protrusion 61 and the groove wall of the first slot E are pressed against each other, so that the waterproof component 60 is stably fixedly connected to the first decorative frame 71. Next, the hook 711 of the first decorative frame 71 is placed inside the opening, so that the hook 711 is fully inserted into the mounting cavity D. The hook 711 abuts against the cavity wall of the mounting cavity D, and its position is located around the periphery of the opening. At this time, the waterproof component 60 is deformed by the compression of the first decorative frame 71 and the fixed horizontal frame 10, and a reaction force is generated, which stably connects the first decorative frame 71 to the fixed horizontal frame 10.

[0078] Understandably, the waterproof component 60 is made of silicone material, which facilitates the stable connection of the first decorative frame 71 to the fixed horizontal frame 10. Alternatively, the waterproof component 60 can be replaced with waterproof adhesive to directly bond the first decorative frame 71 and the fixed horizontal frame 10 (i.e., the waterproof component 60 serves as a medium connecting the first decorative frame 71 and the fixed horizontal frame 10; when the waterproof component 60 is waterproof adhesive, it acts as both a waterproof structure and an adhesive medium).

[0079] In this embodiment, in order to further improve the installation stability of the first decorative frame 71, a deformation groove F can be opened on the protrusion 61, and a screw 80 can be set on the first decorative frame 71. The screw 80 passes through the groove wall of the first decorative frame 71, the first slot E, and the protrusion 61 in sequence, and is threadedly connected to the fixed horizontal frame 10. During this process, the protrusion 61 is deformed by the tightening force of the screw 80, and the deformation groove F provides the deformation space for the protrusion 61.

[0080] In summary, in the curtain wall unit and curtain wall provided by this invention, by designing the curtain wall unit as a structure with a cooling structure using hollow curtain wall glass, when sunlight shines on the curtain wall using the curtain wall unit of this invention, the generated heat radiation is conducted to the cooling structure. The cooling structure isolates the solar heat radiation in the hollow curtain wall glass, preventing heat radiation from being conducted into the room and effectively reducing the indoor temperature. In addition, since there is no need to install additional sunshade devices, it is conducive to sunlight entering the room and ensuring the indoor lighting effect.

Any changes or modifications made by those skilled in the art based on the above disclosure shall fall within the protection scope of the claims.
