Description

Technical Field

[0001] The utility model relates to the technical field of double - layer ventilated curtain walls, and specifically relates to a double - layer convective ventilated curtain wall with a heat dissipation structure. Background Technique

[0002] The double - layer ventilated curtain wall is different from the traditional single - layer curtain wall. It consists of an inner curtain wall and an outer curtain wall. A relatively enclosed space is formed between the inner curtain wall and the outer curtain wall.

[0003] For example, the publication number is: CN219138087U (named a building curtain wall with ventilation and heat dissipation functions), which includes a curtain wall panel. An installation groove is opened on the front side of the curtain wall panel, and a plurality of ventilation holes communicating with the installation groove are opened on the rear side of the curtain wall panel. A plurality of rotating shafts are rotatably installed at the notch of the installation groove. A driving mechanism for driving the rotating shafts to rotate is provided on the curtain wall panel. An activity plate is fixedly sleeved on the rotating shafts. A ventilation fan, a controller and a temperature sensor are arranged in the installation groove. The ventilation fan and the temperature sensor are respectively electrically connected to the controller. When the temperature at the rear side of the curtain wall panel is too high, the temperature sensor sends a signal to the controller, causing the controller to turn on the ventilation fan. At the same time, the driving mechanism drives the rotating shafts to rotate. The rotation of the rotating shafts drives the activity plate to rotate, so that the activity plate is in an inclined state. At this time, air flows between the front and rear sides of the curtain wall panel, and the ventilation fan accelerates the heat dissipation at the rear side of the curtain wall panel. When the temperature at the rear side of the curtain wall panel drops to the normal state, the temperature sensor sends a signal to the controller, the controller turns off the ventilation fan, and at the same time, the driving mechanism drives the rotating shafts to rotate back, driving the activity plate to rotate, so that the activity plate is in a vertical state. A plurality of activity plates jointly close the notch of the installation groove, preventing air from flowing between the front and rear sides of the curtain wall panel, enabling the curtain wall to keep the indoor environment warm. The utility model can ventilate and dissipate heat indoors when the indoor temperature is too high, and keep the indoor environment warm when the indoor temperature is normal.

[0004] The above - mentioned building curtain wall monitors the indoor temperature through the set temperature sensor and conducts synchronous automated ventilation and air - change work. However, the automated work of the ventilated curtain wall has high energy consumption, resulting in a high use cost of the ventilated curtain wall. Therefore, we provide a double - layer convective ventilated curtain wall with a heat dissipation structure. Content of the Utility Model

[0005] The purpose of the utility model is to provide a double - layer convective ventilated curtain wall with a heat dissipation structure, so as to solve the problem that the existing building curtain wall monitors the indoor temperature through the set temperature sensor and conducts synchronous automated ventilation and air - change work, but the automated work of the ventilated curtain wall has high energy consumption, resulting in a high use cost of the ventilated curtain wall as mentioned in the above background technique.

[0006] To achieve the above object, the present utility model provides the following technical solutions: A double-layer convection ventilation curtain wall with a heat dissipation structure, including a floor slab, two curtain wall outer frames are arranged between two floor slabs, an inner wall panel and an outer wall panel are arranged between the two curtain wall outer frames, and the inner wall panel and the outer wall panel are an integral structure with the two curtain wall outer frames;

An exhaust duct is arranged on one side of the air extraction pump, and the exhaust duct is communicated with the inside of one of the diversion channels. One end of the exhaust duct is provided with a plugging cover plate;

[0009] An air inlet port, which is arranged at one end position of the other diversion channel. The air inlet port is an integral structure with one curtain wall outer frame, and a dust filter net is arranged inside the air inlet port. The frame of the dust filter net is fixedly connected to the inner wall of the air inlet port by screws;

[0010] An impeller, which is arranged at one side position of the air inlet port. The impeller and the air inlet port are on the same horizontal line, and a wind power generator is arranged on one side of the impeller. The linkage shaft of the wind power generator is welded to the central position of the impeller;

[0011] A closed frame, which is arranged at the other end position of the other diversion channel, and a filling circular groove is arranged inside the closed frame. A flip plate is movably arranged inside the filling circular groove through a hinge.

[0012] Preferably, two hollow inner cavities are arranged inside the exhaust duct, and two inner connecting insertion rods are welded on the inner wall of the plugging cover plate. The two inner connecting insertion rods are respectively inserted and movably connected with the two hollow inner cavities.

[0013] Preferably, a connecting spring is arranged inside the hollow inner cavity, and both ends of the connecting spring are adhesively fixed to the inner connecting insertion rod and the hollow inner cavity respectively by nail-free glue.

[0017] Compared with the prior art, the beneficial effects of the present utility model are:

[0018] 1. After the indoor air of the present utility model is extracted, negative pressure is generated indoors. At the same time, the flip plate inside the closed frame is opened, so that the air inlet port can circulate air. Since a large amount of indoor air is extracted, outdoor air rushes into the room through the air inlet port under the action of negative pressure, achieving the purpose of convective ventilation and air exchange. When the indoor air rushes into the room, it drives the impeller to rotate, enabling the wind turbine to generate electricity. Since each time the air extraction pump is turned on, it consumes electric energy, and the electric energy generated by wind power compensates for the electric energy consumption indoors, thereby reducing the energy consumption of heat dissipation and air exchange of the double-layer ventilation curtain wall, overcoming the problem that the existing building curtain wall monitors the indoor temperature through the set temperature sensor and conducts synchronous automatic ventilation and air exchange work, but the energy consumption of the automatic work of the ventilation curtain wall is relatively large, resulting in a relatively high use cost of the ventilation curtain wall.

[0019] 2. The indoor air is extracted through the air extraction ducts connected to the air inlet end and the air outlet end of the air extraction pump and discharged through the exhaust duct. When the exhaust duct discharges the indoor air, it overcomes the traction force of the connecting spring and flushes open the blocking cover plate. After the exhaust is completed, the connecting spring pulls the blocking cover plate to fit and seal the exhaust duct, preventing the discharged air from flowing back.

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0027] It further includes:

[0028] A diversion channel 10, which is arranged inside the two curtain wall outer frames 2 and the two floor slabs 1, and an air extraction pump 11 is arranged inside one diversion channel 10. A discharge air pipe 6 is arranged on one side of the air extraction pump 11, and the discharge air pipe 6 is communicated with the inside of one diversion channel 10. One end of the discharge air pipe 6 is provided with a sealing cover plate 7;

[0029] An air inlet port 8, which is arranged at one end position of the other diversion channel 10. The air inlet port 8 and one curtain wall outer frame 2 are of an integral structure, and a dust filter net 9 is arranged inside the air inlet port 8. The frame of the dust filter net 9 is fixedly connected with the inner wall of the air inlet port 8 by screws;

[0030] An impeller 13, which is arranged at one side position of the air inlet port 8. The impeller 13 and the air inlet port 8 are on the same horizontal line, and a wind power generator 14 is arranged on one side of the impeller 13. The linkage shaft of the wind power generator 14 is welded to the central position of the impeller 13;

[0031] A closed frame 15, which is arranged at the other end position of the other diversion channel 10, and a filling circular groove 19 is arranged inside the closed frame 15. A flip plate 20 is movably arranged inside the filling circular groove 19 through a hinge.

[0032] When in use, after the indoor air is extracted, negative pressure is generated indoors. At the same time, the flip plate inside the closed frame is opened, so that the air inlet port can circulate air. Since a large amount of indoor air is extracted, outdoor air rushes into the room through the air inlet port under the action of negative pressure, achieving the purpose of convective ventilation and air exchange. When the indoor air rushes into the room, it drives the impeller to rotate, enabling the wind power generator to generate electricity. Since each time the air extraction pump is turned on, it consumes electric energy, and the electric energy generated by wind power compensates for the electric energy consumption indoors, thereby reducing the energy consumption of the double-layer ventilation curtain wall for heat dissipation and air exchange.

[0033] Please refer to Figure 3 , two hollow inner cavities 16 are arranged inside the discharge air pipe 6. Two inner connecting insertion rods 17 are welded on the inner wall of the sealing cover plate 7. The two inner connecting insertion rods 17 are respectively inserted and movably connected with the two hollow inner cavities 16. The two hollow inner cavities 16 arranged inside the discharge air pipe 6 play a role in guiding the movement of the inner connecting insertion rods 17 and the connecting springs 18.

[0034] Please refer toFigure 3 , a connecting spring 18 is arranged inside the hollow inner cavity 16. The two ends of the connecting spring 18 are adhesively and fixedly connected to the inner connecting rod 17 and the hollow inner cavity 16 respectively through nail-free glue. The connecting spring 18 arranged inside the hollow inner cavity 16 functions to elastically connect the inner connecting rod 17.

[0035] Please refer to Figure 2 , air extraction ducts 12 are respectively arranged at the air inlet end and the air outlet end of the air extraction pump 11. The two air extraction ducts 12 respectively extend into the inside of the diversion channel 10 and the exhaust duct 6. The air extraction ducts 12 respectively arranged at the air inlet end and the air outlet end of the air extraction pump 11 function to assist in air extraction and exhaust.

[0036] Please refer to Figure 4 , a magnet block 21 is embedded on the inner wall of the filling circular groove 19. The flip cover plate 20 is adsorbed and fixedly connected to the closed frame 15 through the magnet block 21. The magnet block 21 embedded on the inner wall of the filling circular groove 19 functions to adsorb the flip cover plate 20.

[0037] Please refer to Figure 1 , curtain wall glass windows 5 are arranged inside both the inner wall panel 3 and the outer wall panel 4. The curtain wall glass windows 5 are mechanically sealed with the inner wall panel 3 and the outer wall panel 4. The curtain wall glass windows 5 arranged inside both the inner wall panel 3 and the outer wall panel 4 function to assist in ventilation and let the curtain wall transmit light.

[0038] Working principle: When heat dissipation is required indoors, the air extraction pump 11 is turned on. The air in the room is extracted through the air extraction ducts 12 connected to the air inlet end and the air outlet end of the air extraction pump 11 and discharged through the exhaust duct 6. When the exhaust duct 6 discharges the indoor air, the plugging cover plate 7 is flushed open against the traction force of the connecting spring 18. After the indoor air is extracted, negative pressure is generated indoors. At the same time, the flip cover plate 20 inside the closed frame 15 is opened, so that the air inlet port 8 can circulate air. Since a large amount of air in the room is extracted, outdoor air rushes into the room through the air inlet port 8 under the action of negative pressure, achieving the purpose of convective ventilation and air exchange. When the indoor air rushes into the room, it drives the impeller 13 to rotate, enabling the wind power generator 14 to generate electricity. Since each time the air extraction pump 11 is turned on, it consumes electric energy, the electric energy generated by wind power compensates for the electric energy consumption indoors, thereby reducing the energy consumption of the double-layer ventilation curtain wall for heat dissipation and air exchange. After the exhaust is completed, the connecting spring 18 pulls the plugging cover plate 7 to fit and seal the exhaust duct 6 to prevent the discharged air from flowing back, completing the use of the double-layer convective ventilation curtain wall with a heat dissipation structure.
