Description

Technical Field

[0001] This application relates to the field of airflow regulation equipment technology, and in particular to an airflow regulation device, an airflow control system, an air conditioning system, and a vehicle. Background Technology

[0002] In related technologies, the collector is installed at the air inlet of a multi-blade centrifugal fan. During operation, the collector guides the airflow into the impeller. Due to the operating characteristics of the multi-blade centrifugal fan, the airflow needs to rotate 90° from axial to radial flow after entering the impeller. This change in airflow direction typically requires a certain height. Because this flow distance is insufficient at the impeller air inlet, the change in flow direction is not achieved effectively, resulting in low inflow and outflow velocities at the impeller air inlet. This leads to low fluid energy in this region, causing flow separation and generating significant aerodynamic noise. Utility Model Content

[0059] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0060] According to the first aspect of this application, please refer to Figures 1 to 3 , Figure 1 This is a three-dimensional structural schematic diagram of an airflow regulating device provided in an embodiment of this application. Figure 2 yes Figure 1 A side view of the provided airflow regulating device. Figure 3 yes Figure 1 The provided airflow regulating device 100 includes: a first ring body 1 with a first opening 11 on its outer surface for gas to flow out; a support component 2 with a first end connected to the outer surface of the first ring body 1 and a second end adapted to be connected to a component to be fixed (not shown in the figure), the second end being disposed away from the first ring body 1; a second opening 21 on the surface of the first ring body 1 and / or the support component 2 for gas to flow in; the first opening 11 and the second opening 21 are connected inside the airflow regulating device and are disposed on opposite sides.

[0061] In this embodiment, a first opening 11 is provided on the outer surface of the first ring body 1, connecting one end of the support component 2 to the outer surface of the first ring body 1. A second opening 21 is provided on the surface of the first ring body 1 and / or the support component 2, with the first opening 11 and the second opening 21 being arranged on opposite sides. Gas flows in through the second opening 21, allowing the gas flowing along the axial direction of the first ring body 1 to enter the first ring body 1 through the second opening 21 and then exit through the first opening 11. However, in this embodiment, the airflow reaches the first ring body 1 and flows throughout the entire first ring body 1. If the first opening 11 and the second opening 21 are located on the same surface, the airflow entering the first ring body 1 will be difficult to exit due to the pressure of the external airflow. Therefore, to ensure that the airflow can smoothly enter and exit the first ring body 1, the first opening 11 and the second opening 21 are arranged on opposite sides in this embodiment, which helps to avoid the situation where the airflow is difficult to exit after entering the first ring body 1 when the first opening 11 and the second opening 21 are located on the same surface. Furthermore, the non-uniform arrangement causes the airflow direction exiting through the first opening 11 to differ from the airflow direction entering through the second opening 21, thus altering the airflow direction and achieving the purpose of regulating the airflow. For example, as... Figure 1 As shown, a second opening 21 is disposed on a support component 2 and faces another support component 2, while a first opening 11 is disposed on the outer circumferential surface of the first ring body 1. Airflow flows in through the second opening 21 and out through the first opening 11, changing the airflow direction from circumferential to radial. Simultaneously, the airflow changes its velocity during the flow process, thus achieving the purpose of regulating the airflow. The arrangement of the first ring body 1 and the support component 2 in this application allows the airflow regulating device 100 provided to be applicable to the air inlets of various devices with air inlets. Before the airflow enters the device, the airflow regulating device 100 pre-treats the airflow, improving the flow separation phenomenon caused by the sudden change in flow direction after entering the device, reducing noise caused by flow separation, and expanding the applicability of the airflow regulating device 100 provided in this application.

[0062] In some embodiments of this application, a cavity (not shown in the figure) is provided inside the ring wall of the first ring body 1; a first opening 11 is provided on the outer surface of the first ring body 1 and communicates with the cavity; a second opening 21 communicates with the cavity.

[0063] In this embodiment, a cavity is provided within the annular wall of the first annular body 1, and both the first opening 11 and the second opening 21 communicate with this cavity. This allows gas flowing along the axial direction of the first annular body 1 to enter the cavity through the second opening 21 and exit through the first opening 11 communicating with the cavity. Because the second opening 21 is located on the surface of the first annular body 1 or the support component 2, the flow direction of the gas is changed after exiting through the aforementioned path, thus achieving the purpose of regulating the airflow.

[0064] In some embodiments of this application, an air passage (not shown in the figure) is provided inside the support component 2. One end of the air passage is connected to the cavity, and the other end penetrates through a surface of the support component 2 to form a second opening 21.

[0065] Please continue reading. Figures 1 to 3 In some embodiments of this application, there are multiple support components 2; the multiple support components 2 are spaced apart along the outer peripheral surface of the first ring body 1.

[0066] In this embodiment, the airflow regulating device has multiple support components 2, allowing the airflow direction to be adjusted using these components, increasing the flow rate of the gas being regulated simultaneously, and thus regulating the flow direction of more gases. Furthermore, the multiple support components 2 are spaced apart, enabling the airflow direction to be adjusted in multiple locations outside the outer surface of the first ring body 1, further increasing the flow rate of the gas being regulated simultaneously, and to a certain extent, uniformizing the gas flow velocity in areas outside the outer surface of the first ring body 1.

[0067] Please continue reading. Figures 1 to 3 In some embodiments of this application, multiple support components 2 are arranged at equal intervals along the outer peripheral surface of the first ring body 1. This approach can uniformly distribute the gas flow velocity across the area outside the outer peripheral surface of the first ring body 1, ensuring that the pressure on the outer peripheral surface of the first ring body 1 is essentially the same, reducing the possibility of damage to the first ring body 1 due to varying pressures at different locations, and improving the reliability of the airflow regulating device 100 provided in this application.

[0068] Please continue reading. Figures 1 to 3 In some embodiments of this application, multiple support components 2 are arranged radially around the first ring body 1.

[0069] In some embodiments of this application, the first annular body 1 has multiple cavities within its annular wall, and each cavity is connected to a support component 2. This allows each support component 2 to have a cavity in communication with it, enabling gas entering the airway to flow out through the first opening 11 of the cavity, thus changing the gas flow direction.

[0070] In some embodiments of this application, the cavity is arranged circumferentially along the first annular body 1, and the cavity is connected end to end.

[0071] This design makes the cavity annular, allowing gas entering the cavity through the air passages of multiple support components 2 to flow within the annular cavity, facilitating the gas to flow out through the first opening 11 and thus changing the gas flow direction.

[0072] Please continue reading. Figures 1 to 3 In some embodiments of this application, the outer peripheral surface of the first annular body 1 is curved. This reduces the resistance of the outer peripheral surface of the first annular body 1 to gas flow and reduces the impact of the outer peripheral surface of the first annular body 1 on the gas flow velocity, thereby ensuring the gas flow rate.

[0073] Please continue reading. Figures 1 to 3 In some embodiments of this application, the first annulus 1 is a circular annulus. This makes the area enclosed by the circular annulus a uniform inflow area, that is, the gas velocity in this area is uniform and the airflow state is good, which can effectively avoid the generation of eddies and turbulence, thereby reducing the vibration of the device.

[0074] Please continue reading. Figures 1 to 3 In some embodiments of this application, the support component 2 includes a connecting plate 22 and an air intake plate 23. The connecting plate 22 is connected between the outer peripheral surface of the first ring body 1 and the air intake plate 23. The air passage includes a first sub-air passage (not shown in the figure) located in the connecting plate 22 and a second sub-air passage (not shown in the figure) located in the air intake plate 23. The second opening 21 is disposed on the air intake plate 23 and communicates with the second sub-air passage.

[0075] In this embodiment, by including a connecting plate 22 and an air inlet plate 23 connected to each other in the support component 2, the connection between the connecting plate 22 and the air inlet plate 23 can be adjusted according to the gas flow direction, etc., to adapt to more airflow adjustment scenarios.

[0076] Please continue reading. Figures 1 to 3 In some embodiments of this application, the connecting plate 22 and the air intake plate 23 are connected in an L-shape.

[0077] In some embodiments of this application, the connecting plate 22 is set at an angle to the axis of the first ring body 1. In this way, the connecting plate 22 can be used to guide the gas to flow in a direction opposite to the tilt direction of the connecting plate 22.

[0078] In some embodiments of this application, in the axial direction of the first ring body 1, the side of the first ring body 1 closer to the component to be fixed is the outflow side, and the air inlet plate 23 extends toward the connecting plate 22 in the direction closer to the outflow side.

[0079] This design facilitates the entry of gas guided by the connecting plate 22 into the gas passage, thereby allowing for the adjustment of the gas flow direction.

[0080] Please continue reading. Figures 1 to 3In some embodiments of this application, the lower surface of the connecting plate 22 and the lower surface of the air inlet plate 23 are coplanar in the axial direction of the first ring body 1. This avoids the connecting plate 22 or the air inlet plate 23 from protruding and obstructing the flow of gas, affecting the gas velocity, and helps to make the gas velocity outside the outer periphery of the first ring body 1 uniform, thereby reducing the possibility of noise caused by uneven gas velocity.

[0081] In some embodiments of this application, the cross-sectional shape of the support component 2 is airfoil-shaped along the axial direction of the first ring body 1, and the second opening 21 is disposed at the pointed end of the airfoil. This helps to ensure a uniform flow velocity of the gas passing through the support component 2, reducing the possibility of noise generation. Furthermore, the airfoil-shaped support component 2 can also reduce gas loss as it flows through it. In embodiments of this application, when the cross-section of the support component 2 is airfoil-shaped, the pointed end of the airfoil is close to the component to be fixed.

[0082] Please see Figure 4 , Figure 4 This is a three-dimensional structural schematic diagram of another airflow regulating device provided in the embodiments of this application. In some embodiments of this application, in the axial direction of the first ring body 1, the side of the first ring body 1 closer to the component to be fixed is the outflow side. The airflow regulating device 100 also includes a second ring body 12, which is connected to the first ring body 1 and located on the outflow side.

[0083] In some embodiments of this application, the outer diameter of the second ring 12 gradually increases in the axial direction of the first ring 1.

[0084] In this embodiment of the application, by providing a second annular body 12 with a gradually increasing outer diameter on the outflow side of the first annular body 1, the gas flowing out through the first opening 11 can flow along the outer peripheral surface of the second annular body 12, so that the gas flow can be guided by the outer peripheral surface of the second annular body 12.

[0085] Please continue reading. Figure 4 In some embodiments of this application, the second ring body 12 is coaxially arranged with the first ring body 1.

[0086] In this embodiment, the gas flows axially. If the first annular body 1 and the second annular body 12 are not coaxially arranged, when the gas flows from the outer peripheral surface of the first annular body 1 to the outer peripheral surface of the second annular body 12, the gas cannot flow smoothly to the outer peripheral surface of the second annular body 12 and needs to change its flow direction to adapt to the position change of the outer peripheral surface. This will lead to local flow turbulence, forming eddies and turbulent regions. These eddies and turbulence will consume the kinetic energy of the gas, reduce the overall gas velocity, and increase energy loss. Therefore, this application arranges the first annular body 1 and the second annular body 12 coaxially, which helps to ensure the gas velocity and reduce the energy loss of the gas when it flows through the outer peripheral surfaces of the first annular body 1 and the second annular body 12.

[0087] In some embodiments of this application, the second ring 12 is a hollow frustum. The beneficial effects are similar to or the same as those of the first ring 1 being a cylinder, and will not be described further here.

[0088] In some embodiments of this application, at the connection between the first ring body 1 and the second ring body 12, the inner diameter of the first ring body 1 is the same as the inner diameter of the second ring body 12, and / or, the outer diameter of the first ring body 1 is the same as the outer diameter of the second ring body 12. This makes the connection between the first ring body 1 and the second ring body 12 smooth and unobstructed, reducing obstruction to the gas and ensuring the gas flow rate.

[0089] In some embodiments of this application, the thickness of the ring wall of the second ring 12 gradually decreases in the direction opposite to the first ring 1 along the axial direction of the first ring 1. This reduces the resistance to gas flow through the second ring 12, thus lowering gas energy loss. Simultaneously, the gradually decreasing ring wall thickness of the second ring 12 ensures a smooth flow between its outer and inner surfaces, further reducing resistance to gas flow and minimizing gas energy loss.

[0090] Please see Figures 1 to 3 In some embodiments of this application, a plurality of first openings 11 are provided on the outer peripheral surface of the first ring body 1, and the plurality of first openings 11 are spaced apart.

[0091] In this embodiment, by spaced-apart multiple first openings 11 communicating with the cavity, it helps to uniformly distribute the gas flow velocity outside the outer circumferential surface of the first annular body 1, reducing the possibility of noise caused by uneven gas flow velocity. Simultaneously, uneven gas flow velocity outside the outer circumferential surface of the first annular body 1 can also lead to different pressures on different parts of the outer circumferential surface of the first annular body 1, increasing the possibility of damage to the first annular body 1. Therefore, the spaced-apart arrangement of multiple first openings 11 in this application also improves the reliability of the airflow regulating device 100 provided in this application.

[0092] Please continue reading. Figures 1 to 3 In some embodiments of this application, a plurality of first openings 11 are arranged in an array.

[0093] This approach ensures that the gas flow rate is basically the same in the area outside the outer circumference of the first annulus 1, which helps to improve the reliability of the airflow regulating device 100 provided in this application and reduce the possibility of noise generation.

[0094] In some embodiments of this application, the support assembly 2 is provided with an air passage connecting the cavity and the second opening 21. Along the axial direction of the first annular body 1, the height of the connection between the air passage and the cavity is equal to the height of the cavity. This maximizes the size of the air passage outlet, helping to reduce noise generated by high-speed airflow. Simultaneously, the lower flow velocity also reduces vibrations caused by airflow impact and eddies, further reducing noise.

[0095] Please continue reading. Figures 1 to 3 In some embodiments of this application, the height of the first ring body 1 is greater than the height of the support component 2 in the axial direction of the first ring body 1, and the upper surface of the first ring body 1 is coplanar with the upper surface of the support component 2.

[0096] Through the above technical solution, a first opening 11 is provided on the outer surface of the first ring body 1, connecting one end of the support component 2 to the outer surface of the first ring body 1. A second opening 21 is provided on the surface of the first ring body 1 and / or the support component 2, with the first and second openings being opposite in orientation. Gas flows into the first ring body 1 through the second opening 21, allowing the gas flowing along the axial direction of the first ring body 1 to enter the first ring body 1 through the second opening 21 and then exit through the first opening 11. This changes the direction of the airflow, achieving the purpose of regulating the airflow.

[0097] According to a second aspect of this application, an airflow control system is provided; please refer to... Figure 5 , Figure 5 This is a schematic diagram of the airflow regulation system provided in the embodiment of this application. The airflow control system includes the airflow regulation device 100 and the gas storage tank 3 as described above. The gas storage tank 3 is configured to store gas.

[0098] Please continue reading. Figure 5 In some embodiments of this application, the above-mentioned airflow control system further includes a control valve 4, which is connected between the gas storage tank 3 and the airflow regulating device 100 and is configured to regulate the gas flow rate entering the airflow regulating device 100.

[0099] Please continue reading. Figure 5 In some embodiments of this application, the airflow control system further includes a controller 5, which is connected to the control valve 4 and configured to control the opening degree of the control valve 4.

[0100] According to a third aspect of this application, an air conditioning system 200 is provided; please refer to [link to relevant documentation]. Figure 6 , Figure 6 This is a three-dimensional structural diagram of an air conditioning system provided in an embodiment of this application. The air conditioning system 200 includes the airflow control system described above, and also includes a collector 6. An airflow regulating device 100 is disposed at the airflow inlet of the collector 6.

[0101] The basic function of the collector 6 is to collect fluid. Taking airflow as an example, the collector 6 can gather the surrounding airflow and guide it to flow in a predetermined direction. Because the surrounding airflows have different directions, some airflows undergo significant changes in direction when entering the collector 6. For example, the flow direction changes from perpendicular to the inlet of the collector 6 to parallel to it. This significant change in airflow direction results in lower inflow and outflow velocities and lower fluid energy at the point of change (i.e., at the inlet of the collector 6), leading to flow separation. Severe flow separation can generate noise. When the airflow regulating device 100 provided in this application is connected to the collector 6, it can pre-change the airflow direction to be parallel to the inlet, improving the flow separation phenomenon at the inlet of the collector 6 and reducing the possibility of noise generation. Furthermore, the airflow entering the collector 6 does not need to undergo a significant change in direction, resulting in a higher airflow velocity, which also improves flow separation.

[0102] The airflow regulating device 100 provided in this application is disposed at the inlet of the collector 6. After the airflow enters the collector 6 in a direction parallel to the axis of the first ring body 1, it will change to a direction perpendicular to the axis of the first ring body 1. This change will result in lower fluid energy at the inlet of the collector 6, causing flow separation and generating aerodynamic noise. However, in this embodiment, by setting the airflow regulating device 100 provided in this application at the inlet of the collector 6, the gas is introduced into the first ring body 1 by the support component 2, and the gas flows out through the first opening 11. The flow direction of the gas is changed from flowing in a direction parallel to the axis of the first ring body 1 to flowing radially along the first ring body 1. Furthermore, because the support component 2 guides the airflow to flow along the outer peripheral surface of the first ring body, the change in gas flow direction is achieved. This allows the airflow to complete the change in flow direction before entering the collector 6. Therefore, the airflow regulating device 100 provided in this application can reduce the possibility of noise generation after the airflow enters the collector 6. Meanwhile, the airflow flowing out from the first opening 11 on the first ring body 1 will have high energy, and after entering the flow channel of the impeller of the collector 6, the flow velocity will be faster, which can improve the flow separation.

[0103] Furthermore, the impeller of the collector 6 draws in air by rotating, which induces a pre-swirling flow in the incoming airflow. The connecting plate 22 of the support assembly 2 of the airflow regulating device 100 provided in this application is set at an angle to the axis of the first ring body 1, allowing the inclined surface of the connecting plate 22 to guide the airflow, counteracting the influence of the impeller on the incoming airflow, thereby improving aerodynamic performance and reducing noise.

[0104] It should be noted that, in the above embodiment, the use of the inclined connecting plate 22 to guide the airflow to counteract the influence of the impeller on the incoming flow requires that the direction of the guided airflow is opposite to the direction of the impeller rotation. For example, when the impeller rotates counterclockwise, the incoming flow will have a pre-flow in the counterclockwise direction. In order to counteract this pre-flow, it is necessary to use the connecting plate 22 to guide the airflow to flow clockwise.

[0105] In some embodiments of this application, the height of the first ring 1 is greater than the height of the support assembly 2 along the axial direction of the first ring 1, and the upper surface of the first ring 1 is coplanar with the upper surface of the support assembly 2. Thus, when the airflow regulating device 100 is placed at the inlet of the collector 6, the distance between the airflow regulating device 100 and the impeller (not shown in the figure) of the collector 6 can be reduced, facilitating the entry of the airflow regulated by the airflow regulating device 100 provided in this application into the collector 6. Furthermore, because the airflow regulating device 100 provided in this application improves the flow separation of the airflow entering the impeller of the collector 6, the flow efficiency of the air conditioning system including the collector 6 is improved, helping to reduce the aerodynamic noise inside the air conditioning system.

[0106] In some embodiments of this application, the air conditioning system 200 further includes a filter (not shown in the figure), disposed on the side of the airflow regulating device 100 away from the collector 6, and configured to filter the gas entering the airflow regulating device 100. Thus, the airflow regulating device 100 provided in this application can be used to support the filter. Furthermore, since filters are prone to deformation after a certain period of use, providing the airflow regulating device 100 between the collector 6 and the filter can also prevent deformed filters from falling into the collector 6.
