Description

Technical Field

[0001] The present invention relates to the technical field of aluminum alloy windows, and particularly relates to a broken bridge energy-saving aluminum alloy window. Background Art

[0002] The broken bridge aluminum profile is applied to the building wall and has a heat insulation effect. It relies on the heat insulation strip in the middle to reduce the direct heat conduction between the inner and outer profiles, achieving an energy-saving effect.

[0003] The aluminum alloy window on the building wall blocks the air flow between the indoor and outdoor. However, there is a ventilation requirement indoors. Whether it is summer or winter, it is necessary to open the window for ventilation at different times every day. Especially, the sealing performance of the existing aluminum alloy doors and windows is getting stronger, and indoor ventilation is particularly important. The most common way of ventilation is to open the window and achieve the ventilation effect through natural air flow, and then close the window after meeting the ventilation duration; in existing buildings, there are also fans independently arranged by opening holes in the wall for ventilation. The existing ventilation methods are all direct air flow exchanges between the indoor and outdoor, resulting in direct energy exchange and wasting energy. For example, in summer, when the air conditioner is turned on indoors to cool down, the low-temperature air is directly discharged outdoors, and the high-temperature air directly enters the room; in winter, when the floor heating or air conditioner is turned on indoors to heat up, the high-temperature air is directly configured outdoors, and the low-temperature air directly enters the room, all of which result in energy waste, and the air flow changes greatly and the temperature changes greatly during ventilation and air change, greatly reducing the comfortable feeling indoors, and the operation of regularly opening and closing the window is relatively troublesome and easy to forget.

[0004] The problem of energy waste caused by the existing aluminum alloy window during ventilation needs to be solved. Summary of the Invention

[0005] The technical problem to be solved by the present invention is, aiming at the above-mentioned existing technical deficiencies, to provide a broken bridge energy-saving aluminum alloy window, which solves the problem of energy waste caused by the existing aluminum alloy window during ventilation.

[0006] The technical solution adopted by the present invention is: to provide a broken bridge energy-saving aluminum alloy window, including an outer profile and an inner profile arranged at intervals relatively. The outer profile and the inner profile are connected by a heat insulation strip, and both the inside of the outer profile and the inside of the inner profile have a frame structure; it is characterized in that the side wall of the inner profile close to the indoor has an inner exhaust port and an inner air inlet, the side wall of the outer profile close to the outdoor has an outer exhaust port and an outer air inlet, and the two frame structures are communicated by a first conduit. Among them, the inner exhaust port, the frame structure inside the inner profile, the first conduit, the frame structure inside the outer profile, and the outer exhaust port are communicated in sequence to form an exhaust channel; further including:

[0007] An intake channel is provided inside the two housing structures, with one end communicating with the inner intake port and the other end communicating with the outer intake port. At least part of the intake channel is located inside the exhaust channel, and heat exchange occurs between the intake channel and the exhaust channel.

[0008] There are at least two driving modules. At least one of the driving modules is arranged inside the intake channel and is used to introduce outdoor air into the room through the intake channel. At least one of the driving modules is arranged inside the exhaust channel and is used to discharge indoor air to the outside through the exhaust channel.

[0009] To further optimize this technical solution, the intake channel includes two heat-conducting boxes, which are respectively arranged inside the two housing structures. The space between the heat-conducting box and the inner wall of the housing structure is the exhaust channel. One side of the heat-conducting box has ventilation holes, and the other side has installation windows. The two ventilation holes are connected through a second conduit. The installation window of the heat-conducting box arranged inside the inner profile communicates with the inner intake port, and the installation window of the heat-conducting box arranged inside the outer profile communicates with the outer intake port.

[0010] To further optimize this technical solution, the cross-section of the intake channel is "n"-shaped.

[0011] To further optimize this technical solution, it further includes:

[0012] There are several positioning pads. The positioning pads are arranged on both opposite sides of the heat-conducting box, and the positioning pads abut against the inner wall of the housing structure.

[0013] To further optimize this technical solution, a silica gel ring is provided around the driving module in a ring shape, and the silica gel ring is sleeved inside the intake channel or the exhaust channel.

[0014] To further optimize this technical solution, it further includes:

[0015] A sunshade is arranged on the outside of the outer profile, and there is a space between the sunshade and the outer side wall of the outer profile, which is used to shade the outer side wall of the outer profile.

[0016] To further optimize this technical solution, it further includes:

[0017] A heat insulation board has one end arranged on the outer profile and the other end arranged on the sunshade. The sunshade is detachably arranged on the outside of the outer profile through the heat insulation board.

[0018] The beneficial effects of the present invention are as follows:

[0019] 1. The indoor and outdoor are connected through two channels, namely the intake channel and the exhaust channel. The driving module drives the gas to flow, and heat exchange occurs between the intake channel and the exhaust channel. When the indoor gas is discharged outdoors and the outdoor gas enters the indoor, heat exchange takes place between the indoor gas and the outdoor gas through heat exchange, preheating or reducing the temperature of the outdoor air in advance, which can reduce energy waste and the change range of indoor temperature during ventilation.

[0020] 2. The driving module drives the gas to flow, and the instantaneous flow intensity of the gas in the whole room is greatly reduced, reducing the direct blowing of strong wind when the window is opened, making it more comfortable overall.

[0021] 3. When the indoor gas is discharged outdoors through the exhaust channel, in addition to heat exchange with the intake channel, it also exchanges heat with the outer profile, utilizing the energy of the exhaust gas to reduce the temperature difference between the outer profile and the inner profile and reduce the energy waste caused by radiation transfer.

[0022] 4. The intake channel is inside the exhaust channel, reducing the direct contact and heat transfer between the outdoor gas and the inner profile. After fully exchanging heat with the exhaust gas, it enters the indoor, making more effective and full use of the energy of the exhaust gas and reducing energy waste.

Detailed implementation manners

[0036] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners.

[0037] For the sake of simplicity of the drawings, only the parts related to the invention are schematically shown in each figure, and they do not represent their actual structures as products. In addition, for the sake of simplicity and easy understanding of the drawings, in some figures, for components with the same structure or function, only one of them is schematically shown, or only one of them is marked. In this article, "one" not only means "only this one", but also can mean "more than one" situation, and "several" includes "two" and "more than two".

[0038] In this article, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0039] In addition, in the description of the present application, the terms "first", "second", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0040] Such as Figures 1 - 12As shown in the figure, a broken bridge energy-saving aluminum alloy window includes an outer profile 101 and an inner profile 102 which are arranged at intervals relatively. The outer profile 101 and the inner profile 102 are connected by a heat insulation strip 103. Both the inside of the outer profile 101 and the inside of the inner profile 102 have a frame structure 104. The side wall of the inner profile 102 close to the indoor has an inner exhaust port 1021 and an inner air inlet 1022. The side wall of the outer profile 101 close to the outdoor has an outer exhaust port 1011 and an outer air inlet 1012. The two frame structures 104 are connected by a first conduit 2. Among them, the inner exhaust port 1021, the frame structure 104 inside the inner profile 102, the first conduit 2, the frame structure 104 inside the outer profile 101 and the outer exhaust port 1011 are connected in sequence to form an exhaust passage 3. It further includes: an intake passage 4, which is arranged inside the two frame structures 104, and one end is connected to the inner air inlet 1022, and the other end is connected to the outer air inlet 1012. The intake passage 4 is at least partially located in the exhaust passage 3, and the intake passage 4 exchanges heat with the exhaust passage 3; a driving module 5, which has at least two. At least one driving module 5 is arranged in the intake passage 4 and is used to introduce the outdoor air into the room through the intake passage 4. At least one driving module 5 is arranged in the exhaust passage 3 and is used to discharge the indoor air to the outdoor through the exhaust passage 3.

[0041] During use, at least part of the intake passage 4 is located in the exhaust passage 3. When the outdoor gas enters the room through the intake passage 4, it exchanges heat with the indoor gas discharged to the outdoor through the exhaust passage 3, so that the new gas entering the room and the discharged gas reach a relative balance in temperature. Taking summer as an example (the same is true in winter), the indoor temperature is relatively low when the air conditioner is turned on, the outdoor temperature is relatively high, and at this time the temperature of the outer profile 101 relative to the inner profile 102 is also high. The heat insulation strip 103 can prevent direct heat conduction between the outer profile 101 and the inner profile 102. When ventilation is required, under the action of the driving module 5, the low-temperature gas in the room is discharged to the outdoor through the exhaust passage 3, and the high-temperature gas outdoors enters the room through the intake passage 4. The intake passage 4 is partially or entirely located in the exhaust passage 3 (that is, the exhaust passage 3 and the intake passage 4 are nested structures inside and outside). The intake passage 4 can be made of a material with good heat conduction performance for heat exchange. The low-temperature gas in the exhaust passage 3 is heated, and the high-temperature gas in the intake passage 4 is cooled. Finally, the temperature of the gas entering the room through the intake passage 4 is close to the indoor temperature, and when the temperature continues to drop, less energy is consumed.

[0042] If the inside of the frame structure 104 is the exhaust passage 3, then the gas in contact with the inner wall of the inner profile 102 is the gas just discharged from the room, and the temperature difference is small, which will not cause a large increase in the temperature of the inner profile 102. Then there is no need for the indoor gas to quickly cool the inner profile 102, and less indoor temperature is wasted. The gas entering the intake passage 4 from the outdoor can fully exchange heat with the gas discharged from the room and then enter the room.

[0043] In the frame structure 104 inside the outer profile 101, when the exhaust passage 3 is in contact with the inner wall of the frame structure 104, the gas discharged from the room can cool the outer profile 101, reducing the temperature difference between the outer profile 101 and the inner profile 102, reducing radiative heat transfer, making full use of the discharged gas without additional consumption.

[0044] The driving module 5, as the power source for gas flow, can adopt devices such as fans and air pumps, and the installation form is selected according to the air flow direction. For example, a fan can be set on the side of the intake passage 4 close to the outdoors, and the fan blows air from the outdoors into the intake passage 4, and another fan can be set on the side of the exhaust passage 3 close to the indoors, and the fan blows air from the indoors into the exhaust passage 3. When the inner profile 102 and the outer profile 101 are relatively small, the adapted fans are relatively small and have limited power, and multiple fans can be arranged at intervals along the air flow direction.

[0045] A filtering device can be set at the port of the intake passage 4 to filter the air. Check valves can be set both in the intake passage 4 and in the exhaust passage 3 to prevent gas backflow and heat conduction when ventilation stops. Plug caps can be set on the side wall of the inner profile 102 close to the indoors and on the side wall of the outer profile 101 close to the outdoors to block the intake passage 4 and the exhaust passage 3, further preventing gas flow when ventilation stops.

[0046] There can be a certain distance between the inner exhaust port 1021 and the inner intake port 1022, and between the outer exhaust port 1011 and the outer intake port 1011, to prevent the discharged gas and the incoming gas from directly mixing. A partition or different guides can also be set in the middle to prevent the gas from directly mixing.

[0047] This application takes the profile structure on one side of the window as an example, and the profiles on the four sides of the quadrilateral window can all be adopted. The ends of the inner profile 102 and the outer profile 101 should be in a sealed state. For the sake of clearly showing the internal state, the drawings are not sealed. The profiles on the four sides of the window can be in a connected state or in an independent sealed state, and ultimately independent gas channels will be formed.

[0048] Furthermore, the intake passage 4 includes two heat conduction boxes 401, which are respectively arranged inside the two frame structures 104. The interval between the heat conduction box 401 and the inner wall of the frame structure 104 is the exhaust passage 3. One side of the heat conduction box 401 has a ventilation hole 4011, and the other side has an installation window 4012. The two ventilation holes 4011 are connected through a second conduit 402. The installation window 4012 of the heat conduction box 401 arranged inside the inner profile 102 is connected to the inner intake port 1022, and the installation window 4012 of the heat conduction box 401 arranged inside the outer profile 101 is connected to the outer intake port 1012.

[0049] In use, two heat-conducting boxes 401 are connected through a second conduit 402 to form an intake passage 4. The two heat-conducting boxes 401 are respectively located within two frame structures 104 (the two frame structures 104 are the frame structures 104 within the inner profile 102 and the frame structures 104 within the outer profile 101). The second conduit 402 is located between the inner profile 102 and the outer profile 101. Inner intake ports 1022 and outer intake ports 1012 are opened at corresponding positions on the side walls of the inner profile 102 and the outer profile 101. At the same time, holes corresponding to the positions of the first conduit 2 and the second conduit 402 are opened on the opposite side walls, facilitating the installation of the heat-conducting box 401 inside the frame structure 104. The installation windows 4012 and ventilation holes 4011 of the heat-conducting box 401 are located on two opposite side walls and are distributed on both sides along the length direction of the heat-conducting box 401, providing a relatively long path for gas flow and facilitating sufficient heat exchange. The two heat-conducting boxes 401 have opposite structures and are relatively installed inside the inner profile 102 and the outer profile 101. The heat-conducting boxes 401 have the same model, with low production costs and convenient installation. Of course, when the cross-sectional areas of the frame structures 104 of the inner profile 102 and the outer profile 101 are different, considering the heat conduction requirements, the two heat-conducting boxes 401 can also be of different sizes.

[0050] Both the first conduit 2 and the second conduit 402 are made of heat-insulating materials. The first conduit 2 can be sleeved outside the second conduit 402 (i.e., the entire intake passage 4 is located within the exhaust passage 3), or they can be arranged side by side (i.e., most of the intake passage 4 is located within the exhaust passage 3).

[0051] Furthermore, the cross-section of the intake passage 4 is "n"-shaped.

[0052] In use; taking the horizontal profiles on the window form as an example, the horizontal cross-section of the intake passage 4 is "n"-shaped. The two heat-conducting boxes 401 and the second conduit 402 form the intake passage 4, and the gas flows in a single direction with a relatively long path. The intake passage 4 can also use a zigzag path to extend the gas flow path and increase the area of heat conduction and exchange. The side walls of the heat-conducting box 401 can be zigzag to increase the area.

[0053] Furthermore, it further includes: positioning pads 6, with several of them. Positioning pads 6 are provided on both opposite sides of the heat-conducting box 401, and the positioning pads 6 abut against the inner walls of the frame structure 104.

[0054] In use, the heat-conducting box is isolated from the inner wall of the frame structure 104 through the positioning pads 6, reducing direct-contact heat conduction, making more use of gas exchange energy. And the positioning pads can be made of rubber material, which can play a role in facilitating installation positioning and noise reduction. The heat-conducting box 401 is inserted into the frame structure 104, and the installation windows 4012 and ventilation holes 4011 are moved to the corresponding positions.

[0055] Further, a silica gel ring 501 is provided annularly around the driving module 5, and the silica gel ring 501 is sleeved in the intake passage 4 or the exhaust passage 3.

[0056] During use, the silica gel ring 501 is sleeved around the driving module 5, which can play a role in shock absorption and noise reduction.

[0057] Further, it also includes: a sunshade 7, which is arranged on the outer side of the outer profile 101 and has a gap with the outer side wall of the outer profile 101 for shading the outer side wall of the outer profile 101.

[0058] During use, the sunshade 7 is arranged outdoors and covers the outer side wall of the outer profile 101. The sunshade 7 can reduce the direct sunlight on the outer profile 101 and reduce the gas flow around the outer profile 101, avoiding the overheating of the outer profile 101 caused by intense sunlight in summer. At the same time, in winter, it can reduce the impact of cold air flow on the outer profile 101, resulting in too low temperature. Since the influence of cold air flow is greater, the energy supplemented by sunlight irradiation is not considered. The sunshade 7 can be inclined, with the upper end connected to the upper side of the outer profile 101 and the lower side inclined outward to form a gap with the outer profile 101. The sunshade 7 can also adopt a bent structure to form an inverted "L" shape and be fixed on the outer side of the outer profile 101, providing shade and having a gap with the outer profile 101. The sunshade 7 can be made of a material with good sunlight reflection performance. The stability of the fixed connection with the outer profile 101 can be enhanced by adding additional bolts, etc. The sunshade 7 can also be used to block the outer air inlet 1012 and the outer exhaust port 1011 on the outer profile 101 for rain protection.

[0059] Further, it also includes: a heat insulation plate 701, with one end arranged on the outer profile 101 and the other end arranged on the sunshade 7. The sunshade 7 is detachably arranged on the outer side of the outer profile 101 through the heat insulation plate 701.

[0060] During use, the sunshade 7 is connected to the outer profile 101 through the heat insulation plate 701, and there is a gap between the sunshade 7 and the outer side wall of the outer profile 101, which can greatly reduce heat conduction. One end of the heat insulation plate 701 can be inserted and sleeved on the outer profile 101, and the other end can adopt an existing insertion and matching structure to form a detachable installation structure with the sunshade 7. The outer side wall of the outer profile 101 can be provided with a groove insertion structure to facilitate the insertion connection with the end of the heat insulation plate 701 and reduce the production difficulty of the heat insulation plate 701.

Additionally, under the teachings of the present invention, these features and embodiments can be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present invention.
