Abstract
Description
Technical Field
[0001] This application relates to the field of airflow guidance and ventilation technology, and in particular to a porous diffused airflow guide hood. Background Technology
[0002] In scenarios such as building ventilation and industrial equipment airflow control, the rational guidance of airflow in corner locations has always been a challenge in the industry. Traditional airflow guiding devices are mostly single guiding structures of conventional shapes, such as flat plates and simple cylindrical types, which have poor adaptability to corner environments and are difficult to fit into the corner space layout of buildings or equipment.
[0003] These traditional devices lack precise control over the dispersion and guidance of airflow. As airflow passes through, it is prone to problems such as concentrated turbulence and uneven dispersion. They cannot make the airflow evenly cover the target area according to the characteristics of the corner space, resulting in poor ventilation effect and low heat dissipation or air supply efficiency of the equipment. Utility Model Content
[0004] To address the problem of uneven airflow distribution at the corners of traditional airflow distribution devices, this invention provides a porous airflow guide hood, comprising: Deflectors and fairings; The guide plate has a plate-like structure with multiple airflow guide holes on its surface. The distance between any two adjacent airflow guide holes gradually decreases from the center of the guide plate toward the edge. The air guide shroud has a hollow structure, with one side covered to fit over the air outlet device and the other side having an outlet hole. The air guide plate matches the airflow guide hole and is embedded in the airflow guide hole.
[0005] In one possible implementation, the diameter of the airflow guide hole is in the range of 0.5-5 mm; The opening ratio of the guide plate is in the range of 20%-70%.
[0006] In one possible implementation, the size of the airflow guide hole gradually increases from the center of the guide plate toward the edge.
[0007] In one possible implementation, the cross-section of the airflow guide hole is circular, square, or polygonal.
[0008] In one possible implementation, the fairing includes: a first fairing and a second fairing; The first and second air guides are elongated structures with hollow interiors and open tops. The top openings of the first and second air guides are adapted to the corresponding air outlet devices, and the first and second air guides are provided with the airflow guide holes. One end of the first flow guide in the longitudinal direction is connected and communicates with one end of the second flow guide in the longitudinal direction, and the longitudinal direction of the first flow guide is perpendicular to the longitudinal direction of the second flow guide.
[0009] In one possible implementation, the first air guide shroud is inclined on the side where the airflow guide hole is located, with the inclination angle in the range of 30-60 degrees. The cross-sectional diameter of the first air deflector gradually decreases from top to bottom along the height direction.
[0010] One possible implementation also includes: a flow guidance framework; The connection point between the first and second air deflectors is designed to avoid collisions. The flow guide frame is a ring-shaped triangular structure, which is disposed between the first flow guide shroud and the second flow guide shroud, and the flow guide frame is inclined and has the flow guide plate embedded in it.
[0011] In one possible implementation, a sealing gasket is provided at the connection between the flow guide frame and the first flow guide cover and the second flow guide cover, and the sealing gasket is made of an elastic sealing material.
[0012] In one possible implementation, the deflector is made of a lightweight, high-strength alloy material and its surface is treated with an anti-corrosion coating.
[0013] In one possible implementation, the outer walls of the first and second air deflectors are provided with reinforcing ribs, which are spaced apart along the length of the air deflectors.
[0014] The beneficial effects of the multi-hole diffuser airflow guide hood in this application embodiment are as follows: It optimizes the hood's aperture, layout, and internal airflow guiding structure, avoiding increased fan load due to excessive pressure drop. It also increases the density of airflow guide holes at the edges or corners of the hood to compensate for velocity attenuation caused by boundary layer separation. Thus, the unique design of the guide plate's hole spacing lays a structural foundation for subsequent precise airflow diffusion and control, providing a reasonable initial layout for airflow guidance.

[0023] like Figures 1-2As shown, the multi-hole diffused airflow guide hood of this application embodiment includes: a guide plate 200 and a guide hood 100. The guide plate 200 has a plate-shaped structure with multiple airflow guide holes on its surface. The distance between any two adjacent airflow guide holes gradually decreases from the center of the guide plate 200 toward the edge. The guide hood 100 has a hollow structure, with one side suitable for covering an air outlet device and the other side having an outlet hole. The guide plate 200 matches the airflow guide holes and is embedded in the airflow guide holes.
[0024] In this specific embodiment, by computational fluid dynamics and, where necessary, simulating airflow path, pressure distribution, and turbulence intensity, the aperture, layout, and internal guiding structure of the guide shroud 100 are optimized to avoid increased fan load due to excessive pressure drop. The density of airflow guide holes is increased at the edges or corners of the guide shroud 100 to compensate for velocity attenuation caused by boundary layer separation. Thus, the unique hole spacing design of the guide plate 200 lays the structural foundation for subsequent precise airflow dispersion and control, providing a reasonable initial layout basis for airflow guidance.
[0025] Specifically, the multi-hole diffused airflow guide shroud 100 of this application is designed for installation at corner positions. It consists of a guide plate 200 and a guide shroud 100. The guide plate 200 is a plate-shaped structure with multiple airflow guide holes. The spacing between adjacent guide holes gradually decreases from the center to the edge. The guide shroud 100 is hollow, covering the air outlet device on one side and having an outlet hole on the other side. The guide plate 200 is adapted to be embedded in the outlet hole.
[0026] It should be noted that the structure of the deflector 200 can be varied and adapted to the structure of the deflector 100.
[0027] In one specific embodiment, the diameter of the airflow guide hole is in the range of 0.5-5mm, and the opening ratio of the guide plate 200 is in the range of 20%-70%. This ensures the airflow throughput and allows the airflow to be initially dispersed or gathered at the guide plate 200 by utilizing reasonable values of diameter and opening ratio, thus adapting to different airflow intensity requirements.
[0028] In one specific embodiment, the size of the airflow guide holes gradually increases from the center of the guide plate 200 towards the edge. Combined with the change in hole spacing, this further optimizes the distribution and guidance of airflow on the guide plate 200. The gradually increasing size of the holes from the center to the edge allows for relatively concentrated airflow at the center and easier diffusion of airflow at the edges, resulting in more uniform and reasonable overall airflow distribution and improved airflow guidance accuracy.
[0029] In one specific embodiment, the cross-section of the airflow guide hole is circular, square, or polygonal. Different cross-sectional shapes can adapt to different airflow characteristics. For example, circular holes allow for smoother airflow, while square holes are easier to process and adapt for specific installation scenarios, thus enriching product application scenarios and structural design options.
[0030] In one specific embodiment, the air guide 100 includes: a first air guide 110 and a second air guide 120. The first air guide 110 and the second air guide 120 are elongated structures with hollow interiors and open tops. The top openings of the first air guide 110 and the second air guide 120 are adapted to corresponding air outlet devices. The first air guide 110 and the second air guide 120 are provided with airflow guide holes. One end of the first air guide 110 in the length direction is connected and communicates with one end of the second air guide 120 in the length direction. The length direction of the first air guide 110 is perpendicular to the length direction of the second air guide 120.
[0031] In this specific embodiment, the elongated and vertically connected design conforms to the characteristics of corner installation space, allowing the air guide shroud 100 to better fit the corner layout of the building or equipment. Simultaneously, the cooperation of two air guide shrouds 100 expands the airflow coverage and direction, adapting to the complex corner airflow requirements.
[0032] In one specific embodiment, the first guide shroud 110 is inclined on the side with the airflow guide hole, with the inclination angle ranging from 30 to 60 degrees. The cross-sectional diameter of the first guide shroud 110 gradually decreases from top to bottom along the height direction. The inclined design adapts to the corner space angle, guiding the airflow to spread in a specific inclined direction. The gradual change in cross-sectional diameter can compress or guide the airflow on the structure of the guide shroud 110 itself, allowing the airflow velocity and direction to be further adjusted when flowing inside the guide shroud 110, thus optimizing the outflow effect.
[0033] In one specific embodiment, the system further includes a flow guide frame 200. The connection point between the first flow guide shroud 110 and the second flow guide shroud 120 is designed to avoid obstruction. The flow guide frame 200 is a ring-shaped triangular structure, positioned between the first flow guide shroud 110 and the second flow guide shroud 120, and is inclined, with a flow guide plate 200 embedded within it. The flow guide frame 200 fills the connection area between the two flow guide shrouds 100. Utilizing its ring-shaped triangle and inclined orientation, it adapts to complex corner spaces. Simultaneously, with the embedded flow guide plate 200, it provides secondary guidance and integration of the airflow at the connection point of the two flow guide shrouds 100, allowing for better fusion and dispersion of airflow from different directions at the corner location, thus improving the continuity and uniformity of airflow guidance in the entire corner area.
[0034] In one specific embodiment, a sealing gasket is provided at the connection between the flow guide frame 200 and the first flow guide shroud 110 and the second flow guide shroud 120. The sealing gasket is made of an elastic sealing material. The elastic sealing gasket can enhance the connection sealing performance, prevent airflow from leaking from the connection gap, and ensure that the airflow is guided in an orderly manner through the flow guide structure. The elastic material adapts to different installation errors and thermal expansion and contraction, maintains connection stability and sealing, makes the air guiding process more efficient, reduces ineffective air leakage, and improves energy utilization and air guiding effect.
[0035] In one specific embodiment, the deflector 200 is made of a lightweight, high-strength alloy material and its surface is treated with an anti-corrosion coating.
[0036] The lightweight design ensures that the overall weight of the fairing 100 is controllable, making it easy to install and requiring less load-bearing capacity from the installation carrier; the high strength makes the fairing 200 less prone to deformation and damage, extending its service life; the anti-corrosion coating can withstand possible humid and corrosive gas environments, ensuring the long-term stable air guiding performance of the fairing 200 and reducing maintenance and replacement costs.
[0037] In one specific embodiment, the outer walls of the first deflector 110 and the second deflector 120 are provided with reinforcing ribs, which are spaced apart along the length of the deflector 100. This enhances the structural strength of the deflector 100. Under the influence of airflow impact and its own gravity, the reinforcing ribs effectively prevent deformation of the elongated deflector 100, ensuring the structural stability and continuous airflow function of the deflector 100. This is especially beneficial in long-term use or complex airflow environments, improving product reliability and durability.
[0038] The various embodiments of this application have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen to best explain the principles, practical application, or improvement of the technology in the market, or to enable others skilled in the art to understand the embodiments disclosed herein.
