Description

Technical Field

[0001] This utility model provides an air outlet structure, and particularly relates to a front air intake and side air outlet structure for a vertical air sail. Background Technology

[0002] While traditional air sail devices can play a role in ventilation and airflow guidance, they have several drawbacks. Firstly, existing devices often employ straight-through or simply bent duct structures, resulting in significant energy loss and high wind resistance during airflow deflection, hindering efficient kinetic energy conversion. Secondly, their inlet and outlet designs are often inadequate; the depth and shape of the inlet channel are not optimized, leading to low wind energy capture efficiency; the fixed size and shape of the outlet make it difficult to generate high-speed airflow, failing to meet the stringent requirements for airflow speed and direction in specific scenarios. Furthermore, their overall layout often occupies a large amount of horizontal space, limiting their application scenarios. Utility Model Content

[0003] To address the aforementioned problems, this application provides a vertical air sail with a front air intake and side air outlet structure, which solves the issues of high wind resistance, low kinetic energy conversion rate, difficult airflow speed control, and large space occupation of existing air sails.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a front air intake and side air exhaust structure for a vertical air sail, including a vertically arranged air sail plate. The air sail plate has a rectangular plate structure, and its front and rear sides are respectively provided with an air intake channel and an air exhaust channel, which are connected to each other. The air sail plate also has a flow guiding structure inside, which is an inclined flow guiding plate used to guide the airflow from the air intake channel to the air exhaust channel.

[0005] Preferably, the air intake channel is a rectangular groove formed on the front of the air tarp, the length direction of the groove is consistent with the length direction of the air tarp, and the opening edge of the groove is flush with the front edge of the air tarp; the inner wall surface of the air intake channel is a smooth plane, and its depth is set along the thickness direction of the air tarp, with a depth of 15mm.

[0006] Preferably, the air outlet channel is located on the side of the air sail and has a cuboid shape. The length of the cuboid is consistent with the height of the air sail, the width is 30mm, and the height is 1200mm. The outlet end edge of the air outlet channel has a rounded chamfer with a chamfer radius of 5mm to reduce the resistance when the air flows out.

[0007] Preferably, the inclination angle of the air guide structure is 45°, one end of the air guide plate is connected to the bottom of the inner wall of the air inlet channel, and the other end extends to the top of the air outlet channel. The surface of the air guide plate is a smooth arc surface.

[0008] Preferably, the air sail is made of aluminum alloy and its surface is anodized; the air sail has a thickness of 3.0 mm, a length of 1800 mm, and a width of 300 mm.

[0009] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0010] This vertical air sail directly captures airflow through a rectangular groove (air intake channel) on its front. After entering along the smooth inner wall, the airflow is precisely guided and steered by an internal 45° inclined arc-shaped guide plate, accelerating its output from the rectangular side air outlet channel. The 15mm depth of the air intake channel optimizes wind energy capture efficiency, while the 30mm narrow slit structure of the side air outlet and its 1200mm height create a high-speed airflow. The 5mm rounded chamfer at the outlet significantly reduces turbulence resistance. Combined with the smooth surface of the aluminum alloy anodized plate, it achieves low-loss airflow steering, ultimately completing the directional airflow process of "front air intake - high-speed side air exhaust" with minimal energy loss. Its advantages are: reducing the wind resistance dead angle of traditional sails through structural integration, using guide plates to force airflow steering to improve kinetic energy conversion rate, narrow side air outlets to enhance jet velocity, and vertical layout to save horizontal space. It is suitable for scenarios such as building ventilation or wind power enhancement.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] It should be noted that the terms "vertical," "horizontal," "up," "down," "left," "right," and similar expressions used in this article are for illustrative purposes only and do not represent the only possible implementation.

[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein in the description of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention; the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0020] like Figure 1 and Figure 2 As shown, the vertical air sail's front air intake and side air outlet structure includes a vertically placed rectangular plate-shaped air sail 1, with interconnected air intake channels 2 and air outlet channels 3 on its front and rear sides, respectively. Inside the air sail 1, an inclined guide plate is also provided as a flow guiding structure 4. This guide plate is inclined at 45°, with one end connected to the bottom of the inner wall of the air intake channel 2 and the other end extending above the inlet of the air outlet channel 3. Its surface is a smooth arc surface, which can guide the airflow smoothly from the air intake channel 2 to the air outlet channel 3, realizing effective air circulation. The air sail 1 is made of aluminum alloy with an anodized surface, with a thickness of 3.0 mm, a length of 1800 mm, and a width of 300 mm.

[0021] In this embodiment, the air inlet channel 2 is a rectangular groove on the front of the air slab 1, with its length direction aligned with the length direction of the air slab 1. The opening edge is flush with the front edge of the air slab 1, the inner wall surface is smooth, and the depth is set along the thickness direction of the air slab 1, with a depth of 15mm. The air outlet channel 3 is located on the side of the air slab 1, and has a cuboid structure. The length direction of the cuboid is aligned with the height direction of the air slab 1, with a width of 30mm and a height of 1200mm. The edge of the outlet end is rounded with a chamfer radius of 5mm.

[0022] The combined components achieve a highly efficient airflow guiding effect. The rectangular groove design of the air inlet channel 2 allows it to face the wind head-on, capturing a large amount of airflow; its 15mm depth and smooth inner wall ensure that the airflow can smoothly enter the air sail 1, reducing resistance and energy loss during airflow entry. The guide structure 4 has a 45° tilt angle, and its smooth arc surface can precisely guide the airflow direction, allowing the airflow to flow smoothly from the air inlet channel 2 to the air outlet channel 3, improving the kinetic energy conversion rate of the airflow. The cuboid structure and 5mm rounded chamfer design of the air outlet channel 3 enable the airflow to form a high-speed airflow when discharged, while reducing airflow resistance and enhancing jet velocity.

[0023] The air sail 1 is made of aluminum alloy and anodized, giving it excellent corrosion resistance and high strength. Its smooth surface also facilitates airflow. The entire device, through its integrated structural design, reduces the wind resistance dead zones of traditional sails, optimizes wind energy capture efficiency, and enhances the directional guidance of airflow. It achieves the process of "front air intake - high-speed side air exhaust" with minimal energy loss, and its vertical layout saves horizontal space, making it suitable for various scenarios such as building ventilation or wind power enhancement.

[0024] like Figure 2 and Figure 3 As shown, the air inlet channel 2 is located on the front of the air panel 1, and is a rectangular groove. Its length direction is consistent with the length direction of the air panel 1, the opening edge is flush with the front edge, the inner wall is smooth, and the depth is 15mm along the thickness direction of the air panel 1. The air outlet channel 3 is located on the side of the air panel 1, and is a cuboid structure. Its length direction is consistent with the height direction of the air panel 1, the width is 30mm and the height is 1200mm. Its outlet end edge is designed with a rounded chamfer with a chamfer radius of 5mm to reduce airflow resistance.

[0025] In this embodiment, the device needs to work in conjunction with existing air handling systems or other related equipment to achieve more efficient and comprehensive functions. For example, before air enters the air inlet duct 2, it may need to be pre-treated by an existing air filtration device to filter out impurities and particulate matter, ensuring that the air entering the device is clean, thereby improving the overall system's operating efficiency and service life. The air filtration device can use common high-efficiency air filters, and its filter material can be selected from high-efficiency filter materials such as polypropylene and glass fiber, which can effectively filter out small particles in the air.

[0026] At the outlet of air outlet duct 3, to better guide the high-speed airflow to the target area, existing air deflector technology can be used to further optimize the airflow direction and distribution. The air deflector typically employs a streamlined design, and its material can be the same aluminum alloy as the air sail 1 to ensure overall structural consistency and durability. Simultaneously, to achieve precise control of airflow speed and direction, existing intelligent control systems can be integrated, using sensors to monitor airflow parameters and controllers to adjust the angle of the deflector or the operating status of other related equipment.

[0027] In terms of materials, the air slab 1 in this device is made of aluminum alloy, which has advantages such as light weight, high strength, and corrosion resistance, making it very suitable for ventilation devices that need to be exposed to air for extended periods. After anodizing, a dense oxide film forms on the surface of the aluminum alloy, further improving its corrosion resistance and wear resistance, while also providing a certain decorative effect. In addition, the inner wall surfaces of the air inlet channel 2 and the air outlet channel 3 are designed with smooth flat or curved surfaces, which can be made of precision-machined aluminum alloy to ensure smooth airflow within the channels and reduce energy loss.

[0028] In use, the airflow enters vertically from the rectangular air inlet channel 2 on the front of the air sail 1, is efficiently guided along a smooth flat groove 15mm deep, and is forced to turn 90° by the internal 45° inclined arc-shaped guide plate 4. The airflow is then guided to precisely converge into the side air outlet channel 3 along the height direction of the air sail 1. It is accelerated to form a high-speed jet within the 30mm wide × 1200mm high cuboid channel, and finally smoothly exited through a 5mm rounded chamfer at the outlet end, achieving low-turbulence directional flow of "vertical air inlet on the front and high-speed horizontal air outlet on the side". Its advantages are: the design of the air inlet channel depth and edge flush maximizes the capture of wind kinetic energy, the arc surface and precise tilt of the guide plate eliminate airflow separation loss, the narrow air outlet channel combined with the chamfered structure increases the jet speed and suppresses energy loss, and the overall structure achieves a vertically compact layout through spatial integration, completing efficient directional wind energy conversion within a limited thickness (3.0mm). It is suitable for active ventilation and wind power enhancement applications in high-density spaces.

[0029] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be determined by the claims.
