DETAILED DESCRIPTION

[0031] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments.

Therefore, they should not be construed as limitations on this utility model.

[0035] Furthermore, the terms "first," "second," and "third" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0036] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0037] As described in the background section, the air duct, as a ventilation device for heat exchange, is used in small, silent prefabricated power plants to reduce radiant heat inside the unit through ventilation and heat dissipation. These devices are typically installed inside the silent prefabricated power plant to form an effective heat dissipation airflow, thereby ensuring that excess heat can be dissipated in a timely manner during unit operation, preventing performance degradation or malfunctions caused by overheating.

[0038] However, existing wind tunnel designs have some problems in practical applications. Due to the static pressure difference generated during the air exchange process inside and outside the wind tunnel, the airflow will generate large turbulence and eddies when passing through the wind tunnel, resulting in significant noise.

[0039] Based on the above, this utility model provides a wind duct, an air supply device, and a heat dissipation system. An air duct is set inside the outer shell of the wind duct. By setting a baffle in the air duct, the flow direction of the airflow from the air inlet to the air outlet is changed, thereby changing the direction of noise propagation generated by the airflow in the wind duct and the noise generated by the resistance reduction, so that the wind duct achieves the effect of low pressure and quietness.

[0040] The following is an exemplary description of the wind turbine 10 provided in the embodiment of this utility model:

[0041] Please see Figure 1 , Figure 2 The air duct 10 includes a housing 11 and a wind deflector 13. The housing 11 is provided with an air duct 12 and an air inlet 111 and an air outlet 112 connected to the air duct 12. The wind deflector 13 is connected to the housing 11 and located inside the air duct 12, and is used to change the flow direction of airflow from the air inlet 111 to the air outlet 112.

[0042] Depend on Figure 1 , Figure 2 As can be seen, the outer shell 11 is the main frame of the entire air duct 10, and the air duct 12 is provided inside. The air duct 12 is the channel through which the gas flows inside the air duct 10. The air inlet 111 is the inlet for the gas to enter the air duct 12, and the air outlet 112 is the outlet for the gas to flow out of the air duct 12. The wind baffle 13 is connected to the outer shell 11 and is located inside the air duct 12. The main function of the wind baffle 13 is to change the flow direction of the airflow from the air inlet 111 to the air outlet 112.

[0043] If installed in the power plant unit room, an exhaust fan is installed at the air outlet 112. Heat in the unit room enters the air duct 12 through the air inlet 111. The airflow encounters the baffle 13 in the air duct 12. Due to the presence of the baffle 13, the direction of the airflow is changed. After the direction of heat flow is changed by the baffle 13, the airflow is discharged to the outside through the air outlet 112 via the air duct 12, achieving a heat dissipation effect. Furthermore, because the airflow is blocked by the baffle 13, the direction of the airflow is changed. When the airflow changes direction, eddies and turbulence are generated. These eddies and turbulence can disperse and weaken the kinetic energy of the airflow, reducing the possibility of high-speed airflow directly impacting the wall of the outer casing 11 or other components, thereby reducing the noise generated by the airflow impact. Since the baffle 13 changes the direction of the airflow, it also affects the propagation path of the sound waves. When the sound waves encounter the baffle 13, they will be reflected and refracted, causing the direction of sound wave propagation to change. Different reflection and refraction paths will cause the sound waves to form interference phenomena in space. Some sound waves may cancel each other out, thereby reducing the overall noise level and enabling the air duct 10 to achieve a low-pressure quiet effect.

[0044] In one possible implementation, please refer to Figure 3 , Figure 4 The wind deflector 13 includes a first wind deflector 131 and a second wind deflector 132; the first wind deflector 131 and the second wind deflector 132 divide the air duct 12 into an air inlet chamber 121, a transition chamber 122 and an air outlet chamber 123.

[0045] Combination Figure 3 , Figure 4As shown in the figure, the first baffle plate 131 divides the outer shell 11 of the air duct 10 into upper and lower parts. The lower part is the exhaust chamber 123 of the air duct 12, and the upper part is further divided into left and right parts by the second baffle plate 132. The left part is the air inlet chamber 121 of the air duct 12, and the right part is the exhaust chamber 123 of the air duct 12.

[0046] The airflow in the air duct 12 of the air duct 10 is as follows: the airflow enters the air inlet chamber 121 through the air inlet 111. The airflow is blocked by the outer shell 11, the first baffle plate 131 and the second baffle plate 132 in the air inlet chamber 121. The airflow enters the transition chamber 122 from one side of the air inlet chamber 121. The airflow is blocked by the outer shell 11 and the first baffle plate 131 in the transition chamber 122. The airflow enters the exhaust chamber 123 from the opening of the transition chamber 122. Finally, the airflow is discharged from the air duct 10 through the air outlet 112 from the exhaust chamber 123.

[0047] In one possible implementation, see Figure 5 , Figure 6 The outer casing 11 includes a back plate 113, a top plate 114, a bottom plate 115, a first side plate 116, a second side plate 117, a front plate 118, and a fan mounting plate 119.

[0048] The connection between the back panel 113, top panel 114, front panel 118, first side panel 116, second side panel 117, first wind deflector 131 and second wind deflector 132 forms the air intake chamber 121 and the transition chamber 122.

[0049] Optionally, refer to Figure 7 The first baffle plate 131 can be an L-shaped baffle, including a wide plate 1311 and a narrow plate 1312. The first baffle plate 131 is used to isolate the exhaust chamber 123 from the air inlet chamber 121 and the transition chamber 122. The second baffle plate 132 is set at an angle to the first baffle plate 131 and is connected to the wide plate 1311. It is used to isolate the air inlet chamber 121 from the transition chamber 122. The width of the second baffle plate 132 is smaller than the width of the wide plate 1311.

[0050] The first baffle plate 131 is an L-shaped baffle, composed of a wide plate 1311 and a narrow plate 1312. The first baffle plate 131, together with the back plate 113, the top plate 114, the front plate 118, the first side plate 116, and the second side plate 117, forms an air inlet chamber 121 and a transition chamber 122. The first baffle plate 131 can be parallel to the top plate 114. The second baffle plate 132 is connected to the wide plate 1311 and the top plate 114 of the first baffle plate 131 by means of its upper and lower parts respectively. The width of the second baffle plate 132 is smaller than the width of the wide plate 1311, so there is a distance between the second baffle plate 132 and the front plate 118, forming an opening that allows airflow to enter the transition chamber 122 from the air inlet chamber 121. Since the first baffle plate 131 is an L-shaped baffle, after the first baffle plate 131 is connected to the outer shell 11, there will still be an opening for airflow to enter the exhaust chamber 123 from the transition chamber 122.

[0051] Optionally, the angle between the second baffle 132 and the first baffle 131 is 90 degrees. That is, the second baffle 132 is perpendicular to the first baffle 131 and the top plate 114. The 90-degree angle design makes the connection between the second baffle 132 and the first baffle 131 more stable, and also supports the top plate 114, enhancing the stability of the overall structure. It also helps to evenly distribute airflow in the air inlet chamber 121 and the transition chamber 122, improving the uniformity and efficiency of airflow.

[0052] Optionally, the length and width of the second wind deflector 132 are the same as the length and width of the opening of the first wind deflector 131, and one end of the second wind deflector 132 only contacts the wide plate 1311. It can be understood that the shape of the second wind deflector 132 is the same as the shape of the opening of the first wind deflector 131, and the second wind deflector 132 and the opening of the first wind deflector 131 can form a rectangle.

[0053] The wind hopper 10 can be understood from another perspective. A wind deflector is horizontally placed inside the outer shell 11 of the wind hopper 10, dividing the outer shell 11 into upper and lower parts. One corner of the wind deflector is then cut off, for example, one-quarter of the wind deflector, to serve as the second wind deflector 132. The remaining three-quarters serve as the first wind deflector 131. The second wind deflector 132 is then vertically placed and connected to the first wind deflector 131 and the top plate 114 of the outer shell 11 to form the structure of the wind hopper 10.

[0054] Optionally, the air inlet 111 is disposed on the back plate 113 and located in the air inlet chamber 121. The air inlet 111 includes multiple through holes, and the through holes are distributed in a mesh pattern in the air inlet 111.

[0055] The size of the air inlet 111 can be the same as the size of the side of the air inlet chamber 121 near the back panel 113, so that a larger airflow can enter from the air inlet 111. The size of the air inlet 111 can also be the same as the size of the side of the air inlet chamber 121 near the back panel 113.

[0056] The air inlet 111 can be a single, continuous opening or a network of smaller openings arranged in a mesh pattern. This mesh pattern reduces turbulence during airflow, allowing for a smoother entry into the duct 12. Each opening provides a small inlet, reducing the impact force of the incoming airflow. The mesh design also acts as a filter, preventing larger particles and debris from entering the duct 12 and protecting the internal structure from contamination.

[0057] Optionally, the air outlet 112 is disposed on the fan mounting plate 119 and located in the exhaust chamber 123, and the air outlet 112 is a circular hole.

[0058] like Figure 6 As shown, a circular air outlet 112 is provided on the fan mounting plate 119 of the exhaust chamber 123. The fan mounting plate 119 is used to install the fan. The shape of the air outlet 112 can also be square, rectangular, etc., as long as it matches the shape of the fan.

[0059] Furthermore, this embodiment of the invention also provides an air supply device, including a fan and the air duct 10 as described above.

[0060] When the air supply device is working, the fan can draw air from the air outlet 112, so that the airflow in the room is discharged from the air duct 10.

[0061] Furthermore, this utility model embodiment also provides a heat dissipation system, including multiple air supply devices as described above.

[0062] Installing a heat dissipation system in various indoor spaces can effectively expel indoor air without generating significant noise.

[0063] In summary, the wind duct, air supply device, and heat dissipation system provided by this utility model embodiment have an air duct set inside the wind duct shell. By placing a wind deflector in the air duct, the airflow can be guided to flow in a predetermined direction. When the airflow encounters the wind deflector, it will be forced to change its flow direction. When the airflow changes direction, it will generate eddies and turbulence. These eddies and turbulence can disperse and weaken the kinetic energy of the airflow, reducing the possibility of high-speed airflow directly impacting the shell wall or other components, thereby reducing the noise generated by airflow impact. Since the wind deflector changes the direction of airflow, it will also affect the propagation path of sound waves. When the sound waves encounter the wind deflector, they will be reflected and refracted, causing the direction of sound wave propagation to change. Different reflection and refraction paths will cause the sound waves to form interference phenomena in space. Some sound waves may cancel each other out, thereby reducing the overall noise level and enabling the wind duct to achieve a low-pressure and quiet effect.

[0064] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.

[0065] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
