Description

Technical Field

[0001] This application relates to the field of electronic equipment technology, and more specifically, to an air outlet assembly and cabinet. Background Technology

[0002] In current energy storage power stations, the energy conversion losses caused by medium-voltage dry-type transformers during energy storage and release are mainly dissipated into the station environment as heat. With the continuous expansion of energy storage power station scale, especially in compact centralized layouts, the problem of heat accumulation caused by large-scale energy conversion is becoming increasingly prominent. If this heat cannot be effectively dissipated, a heat island effect will form around the power station, threatening not only the stability of the power grid but also affecting the operating efficiency of the equipment and potentially endangering environmental safety. In related technologies, to eliminate the heat island effect, the exhaust components often adopt an upward exhaust design, utilizing the principle of hot air rising naturally to dissipate the accumulated heat. However, this upward exhaust design brings challenges in waterproofing.

[0003] In conclusion, how to solve the waterproofing problem when the air outlet assembly exhausts air upwards has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] In view of this, the purpose of this application is to provide an air outlet assembly to solve the waterproofing problem when the air outlet assembly exhausts air upwards.

[0005] Another object of this application is to provide a cabinet including the above-mentioned air outlet components.

[0006] To achieve the above objectives, this application provides the following technical solution:

[0007] An air outlet assembly, comprising:

[0008] The air outlet body is provided with an air duct, which has an air inlet and an air outlet. An air duct plate extending from the air inlet to the air outlet is provided in the air duct. The air duct plate divides the air duct into multiple air outlet channels, and the air outlet channels are inclined upwards in the guiding direction corresponding to the side of the air outlet.

[0009] A blade assembly is disposed at the air inlet. The blade assembly has a first form and a second form and can switch back and forth between the first form and the second form. When the blade assembly is in the first form, the air inlet is closed, and when the blade assembly is in the second form, the air inlet is open.

[0010] In some embodiments of this application, the blade assembly includes:

[0011] A mounting bracket is provided at the air inlet, and the mounting bracket has at least one mounting window;

[0012] An air outlet blade is rotatably disposed in the installation window. The air outlet blade has a first rotatable position and a second rotatable position. When the air outlet blade is in the first rotatable position, the air outlet blade blocks the installation window. When the air outlet blade is in the second rotatable position, the air outlet blade opens the installation window.

[0013] In some embodiments of this application, each of the installation windows is provided with a plurality of air outlet blades, and the air outlet blades located in the same installation window are connected by a linkage component.

[0014] In some embodiments of this application, the linkage component includes:

[0015] The first linkage bracket is hinged to each of the air outlet blades within the same installation window;

[0016] The second linkage bracket is hinged to each of the first linkage brackets within the same mounting window.

[0017] In some embodiments of this application, a counterweight structure is provided on the air outlet blades;

[0018] When the air outlet blade is in the first swing position, the air outlet blade is attached to the window frame of the installation window under the action of the counterweight structure.

[0019] In some embodiments of this application, the counterweight structure is configured such that the air outlet blades protrude to one side of the air outlet to form a counterweight protrusion.

[0020] In some embodiments of this application, the side of the counterweight protrusion facing the air inlet forms an adapter groove, and the window frame of the mounting window is provided with an adapter protrusion;

[0021] When the air outlet blade is in the first swing position, the adapter protrusion is embedded in the adapter groove and fits against the inner wall of the adapter groove.

[0022] In some embodiments of this application, the mounting bracket and / or the air outlet blade is provided with a limiting part, which restricts the rotation of the air outlet blade from the first swing position toward the air inlet.

[0023] In some embodiments of this application, the swing axis of the air outlet blade is offset from the center of gravity of the air outlet blade, so that the air outlet blade has a tendency to swing towards the first swing position under its own weight, and can swing from the first swing position to the second swing position under the pushing action of the airflow blowing towards the air inlet.

[0024] In some embodiments of this application, the swing shaft is disposed at the top of the air outlet blade along a first direction, which is the opposite direction of gravity.

[0025] In some embodiments of this application, the blade assembly further includes an elastic element disposed between the air outlet blade and the window frame of the mounting window to provide an elastic force to the air outlet blade to maintain it in the first swing position, and to swing from the first swing position to the second swing position under the pushing action of the airflow blowing toward the air inlet.

[0026] In some embodiments of this application, the air outlet duct includes at least two interconnected air outlet branches, with adjacent air outlet branches arranged at an angle.

[0027] In some embodiments of this application, a guide vane is also provided on the side of the air duct corresponding to the air inlet;

[0028] The air guide plate is disposed in the air duct, and one end of the air guide plate is connected to the air outlet body, and the other end extends to the air outlet channel to guide the airflow into the air outlet channel.

[0029] In some embodiments of this application, the air outlet body has a mounting surface, the air inlet is disposed on the mounting surface, and a sealing element is disposed on the mounting surface.

[0030] In some embodiments of this application, the mounting surface is provided with reinforcing ribs, and the reinforcing ribs are used to limit the compression of the seal.

[0031] In some embodiments of this application, a ventilation protection component is provided at the air outlet.

[0032] To address the waterproofing issue of upward-exhausting air assemblies, this application provides an air exhaust assembly for installation on equipment such as server racks that require ventilation. The assembly includes an exhaust body and a blade assembly. The exhaust body has an air duct for airflow, with an inlet and an outlet. An air duct plate extending from the inlet to the outlet is installed within the duct, dividing it into multiple exhaust channels. The airflow direction of each exhaust channel corresponding to the outlet is inclined upwards. This duct structure, due to the air duct plate dividing the duct into multiple exhaust channels and the upward-inclined airflow direction of each exhaust channel corresponding to the outlet, provides a significant improvement. The tilted design ensures that all airflow at the outlet is discharged upwards, fulfilling the basic requirement of upward ventilation. Simultaneously, the blade assembly, positioned within the duct corresponding to the air inlet, has a first and a second configuration that can switch between them. In the first configuration, the air inlet is closed, preventing rainwater, dust, and debris from entering the duct through the outlet from flowing back into the device. In the second configuration, the air inlet is open, allowing normal airflow for exhaust. Therefore, the exhaust assembly provided in this application achieves both upward ventilation and excellent waterproofing.

[0033] This application also provides a cabinet, including a cabinet body and the aforementioned air outlet assembly, wherein the air outlet assembly is disposed in the cabinet body and the air inlet communicates with the internal space of the cabinet body.

[0068] The core of this application is to provide an air outlet component to solve the waterproofing problem when the air outlet component exhausts air upwards.

[0069] Another key aspect of this application is to provide a cabinet that includes the aforementioned air outlet components.

[0070] Hereinafter, embodiments will be described with reference to the accompanying drawings. Furthermore, the embodiments shown below do not limit the scope of the utility model as described in the claims. Additionally, the complete contents of the structures represented in the embodiments below are not limited to those necessary for the solution of the utility model as described in the claims. It should be noted that, for ease of description, only the parts relevant to the utility model are shown in the drawings. Unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0071] In energy storage power stations, if the heat generated during energy storage and release by medium-voltage dry-type box-type transformers cannot be effectively dissipated, it can lead to an internal heat island effect, jeopardizing grid stability and equipment efficiency. To meet heat dissipation requirements, the cabinets of medium-voltage dry-type box-type transformers often adopt an upward exhaust design, utilizing the rising of hot air to alleviate the internal heat island effect, but this increases the technical challenges of waterproofing. As the scale of power stations expands, this contradiction becomes particularly prominent in densely packed layouts.

[0072] Based on this, one embodiment of this application provides an air outlet component that is applied to the main body of equipment with ventilation requirements, such as cabinets (e.g., medium-voltage dry-type transformer substations), to solve the waterproofing problem when the air outlet component exhausts air upwards.

[0073] Specifically, refer to Figure 1 and Figure 2 , Figure 1 and Figure 2 The diagram shows an isometric view of the air outlet assembly in the directions of the air inlet 131 and the air outlet 132. The air outlet assembly provided in this application includes an air outlet body 100 and a blade assembly 200.

[0074] Among them, reference Figure 4 and Figure 5 , Figure 4 and Figure 5 The diagram shows structural schematics of the blade assembly 200 in its first and second configurations. An air duct 130 is provided on the air outlet body 100 for airflow. The air duct 130 has an air inlet 131 and an air outlet 132. An air duct plate 250 extending from the air inlet 131 to the air outlet 132 is provided within the air duct 130. The air duct plate 250 divides the air duct 130 into multiple air outlet channels, and the airflow direction of the air outlet channels corresponding to the side of the air outlet 132 is inclined upwards. (See reference...) Figure 5 The airflow direction arrow is shown; the blade assembly 200 is disposed on the air outlet body 100 and arranged in the air duct 130 at the position corresponding to the air inlet 131. The blade assembly 200 has a first form and a second form, and can switch back and forth between the first form and the second form; specifically, when the blade assembly 200 is in the first form, the blade assembly 200 blocks the air inlet 131 of the air duct 130, and the air inlet 131 is closed at this time; when the blade assembly 200 is in the second form, the air inlet 131 is open, and the airflow can pass through the air duct 130 normally to achieve exhaust.

[0075] When this air outlet assembly is applied to equipment with ventilation requirements, such as cabinets (e.g., medium-voltage dry-type transformer substations), the air duct plate 250 divides the air duct 130 into multiple air outlet channels. Furthermore, the airflow direction of each air outlet channel corresponding to the air outlet 132 is designed to be upward-sloping. This ensures that the airflow at the entire air outlet 132 is discharged in an upward-sloping manner, meeting the basic requirement of upward ventilation. Simultaneously, because the blade assembly 200 is arranged within the air duct 130 corresponding to the air inlet 131, and... The blade assembly 200 has a first form and a second form, and can switch back and forth between the two forms. When the blade assembly 200 is in the first form, the air inlet 131 is closed. At this time, rainwater, dust, debris, etc. that may enter the air duct 130 from the air outlet 132 will be intercepted by the blade assembly 200 and will not enter the main body of the equipment through the air inlet 131. When the blade assembly 200 is in the second form, the air inlet 131 is open, and the airflow can pass through the air duct 130 normally to achieve exhaust. Therefore, the air outlet assembly provided in this application can achieve good waterproof performance while satisfying upward exhaust.

[0076] Taking an air outlet assembly installed on the side or top of a server rack as an example, the air duct 130 of the air outlet assembly is connected to the internal space of the server rack. High-temperature airflow inside the rack can be exhausted outwards through the air duct 130 under the action of a fan. The air outlet assembly guides the airflow direction. Furthermore, by setting the blade assembly 200, the air duct 130 can only be opened and allow airflow when the blade assembly 200 is in its second configuration. Rainwater, dust, debris, etc., that might enter the air duct 130 through the air outlet 132 will be intercepted by the blade assembly 200 and will not enter the server rack in the opposite direction through the air inlet 131. This air outlet assembly not only meets the requirement of upward exhaust but also has excellent waterproof performance.

[0077] In a specific embodiment provided in this application, reference is made to Figure 7 , Figure 7 The diagram shows a schematic of a blade assembly 200 in a first configuration. Specifically, the blade assembly 200 may include a mounting bracket 211 and an outlet blade 220. The mounting bracket 211 can be installed on the outlet body 100 at a position corresponding to the air inlet 131 using methods such as screwing, snap-fitting, or plugging. The mounting bracket 211 has an installation window, and the number of installation windows is at least one, meaning it can be a single window or a combination of windows. Figure 3 The multiple (shown) Figure 3 The diagram shows four installation windows, which can be designed according to the dimensions of the entire air inlet 131 and the installation windows. The opening structure of each installation window together constitutes the air inlet 131. The air outlet blades 220 are rotatably mounted on the installation windows. For example, one side of the air outlet blades 220 is hinged to the installation window via a pivot shaft. The pivot shaft can be a press-fit rod pin or other shaft structure.

[0078] In addition, the air outlet blade 220 has a first swing position and a second swing position. When the air outlet blade 220 is in the first swing position, the air outlet blades 220 on each installation window block their respective installation windows to close the air inlet 131, or in other words, separate the air inlet 131 and the air outlet 132 of the air duct 130. When the air outlet blade 220 is in the second swing position, the air outlet blades 220 on each installation window open their respective installation windows, at which time the air inlet 131 opens, or in other words, the air inlet 131 and the air outlet 132 of the air duct 130 are connected.

[0079] It should be noted that the mounting bracket 211 can be, but is not limited to, a frame structure connected by multiple connecting rods and bolts. For example, it can also be a frame structure welded from multiple rods. Furthermore, the number of exhaust blades 220 installed in each mounting window is not limited, as long as it is sufficient to seal the mounting window.

[0080] It should also be noted that the method by which the blade assembly 200 switches between the first and second forms is not limited to... Figure 4 and Figure 7 The swinging method shown can also be rotation, rolling shutter, or translation. For example, if the space where the air inlet 131 is located is relatively open, and the air duct plate 250 has sufficient clearance on the side corresponding to the air inlet 131, the blade assembly 200 can be designed as a plate-like structure using a central symmetry line as the rotation axis, and the air inlet 131 can be opened and closed by rotation. Alternatively, the blade assembly 200 can also be designed as a rolling shutter structure, and the air inlet 131 can be opened and closed by a rolling mechanism. Furthermore, the blade assembly can also be designed as a drive mechanism that drives the blades to translate, thereby opening and closing the air inlet 131. In practical applications, the configuration can be selected according to actual needs.

[0081] In a further embodiment, when the blade assembly 200 is designed with a structure including a mounting bracket 211 and an outlet blade 220, refer to Figure 6 and Figure 7 ,in, Figure 6 The diagram shows the structure of the air outlet assembly after removing the outlet blades 220. The blade assembly 200 can adopt a modular design. The mounting bracket 211 can be installed on the air outlet body 100 through the component bracket 210. The component bracket 210 can divide the air inlet 131 into multiple areas (each area corresponds to a mounting window). Each area can install a set of blade assemblies 200, achieving a rectangular array distribution of the blade assemblies 200. The modular design of the blade assembly 200 facilitates adjusting the number of blade assemblies 200 and assembling them according to the actual size of the air duct 130.

[0082] In a further implementation plan, refer to Figure 7 The air outlet assembly may also include a linkage component 230. Each installation window is equipped with multiple air outlet blades 220, and the air outlet blades 220 located in the same installation window are connected by the linkage component 230. By designing the linkage component 230, the air outlet blades 220 in the same installation window can be opened and closed in a coordinated manner, and each air outlet blade 220 moves synchronously. This can effectively reduce the deflection of different air outlet blades 220 at different angles, thereby reducing airflow turbulence and noise.

[0083] For example, continue to refer to Figure 7The aforementioned linkage component 230 may specifically include a first linkage bracket 231 and a second linkage bracket 232. The first linkage bracket 231 is hinged to each of the air outlet blades 220 within the same installation window, and the second linkage bracket 232 is hinged to each of the first linkage brackets 231 within the same installation window. Both the first linkage bracket 231 and the second linkage bracket 232 can be rod-shaped structures, and the matrix array of air outlet blades 220 facilitates the arrangement of the rod-shaped linkage component 230.

[0084] To ensure reliable sealing of the installation window by the air outlet blades 220, a counterweight structure can be provided on the air outlet blades 220. For example, the counterweight structure can be, but is not limited to, positioned on the side facing away from the air inlet 131. This counterweight structure ensures that when the air outlet blades 220 are in the first swing position, they can reliably rest against the frame of the installation window under their own weight, thus guaranteeing the sealing effect. Specifically, through the counterweight structure, during actual use, because the center of gravity of the air outlet blades 220 shifts away from the air inlet 131, the line connecting the hinge position of the air outlet blades 220 and the center of gravity of the air outlet blades 220 forms an angle θ with the vertical direction. At this point, the air outlet blades 220 tend to rest against the frame of the installation window under the influence of gravity.

[0085] For example, Figure 8 The diagram illustrates a technical solution where the air outlet blade 220 protrudes towards the side where the air outlet 132 is located to form a counterweight protrusion 222, which can be configured as the counterweight structure described above. Alternatively, a counterweight block can be provided on the side of the air outlet blade 220 facing away from the air inlet 131 to serve as a counterweight structure.

[0086] In a further implementation plan, refer to Figure 8 The counterweight protrusion 222 forms an adapter groove 223 on the side facing the air inlet 131. An adapter protrusion (not shown in the figure) is provided on the window frame of the installation window. When the air outlet blade 220 is in its first position, the adapter protrusion is embedded in the adapter groove 223 formed by the counterweight protrusion 222 and fits against the inner wall of the adapter groove 223. The surface contact between the adapter protrusion and the adapter groove 223 ensures a reliable sealing effect of the air outlet blade 220 on the installation window, thereby improving waterproof performance.

[0087] Reference Figure 4This paper illustrates a technical solution in which a limiting part 140 is provided on the air outlet body 100 and / or the air outlet blade 220. When the air outlet blade 220 is subjected to wind force from the direction of the air inlet 131, the limiting part 140 does not limit the movement of the air outlet blade 220. At that time, the air outlet blade 220 can be held in the first swing position under the action of its own weight and / or the action of the elastic element. When the air outlet blade 220 is subjected to wind force from the direction of the air outlet 132, the air outlet blade 220 abuts against the limiting part 140 and is limited, so as to be held in the first swing position by the limiting part 140 and prevent the air outlet blade 220 from moving towards the direction of the air inlet 131. The limiting part 140 ensures that the exhaust blade 220 can only move in one direction, thus allowing airflow in the air duct 130 only from the air inlet 131 to the air outlet 132. This prevents external airflow from entering the cabinet through the air duct 130, greatly reducing the likelihood of impurities in the outside air affecting the components inside the cabinet. For example, the limiting part 140 can be a limiting block structure installed on the exhaust body 100 and arranged on the side of the exhaust blade 220 near the air inlet 131.

[0088] In some specific implementation plans, refer to Figure 4 and Figure 5 As shown, the switching of the blade assembly 200 from the first configuration to the second configuration can be achieved by the airflow flowing within the duct 130. Furthermore, the blade assembly 200 can be configured to maintain a tendency to move in the first configuration under its own weight and / or the action of an elastic element.

[0089] For example, the blade assembly 200 is configured to have a tendency to maintain a first shape under its own weight: the pivot axis of the outlet blade 220 is offset from the center of gravity of the outlet blade 220, so that the outlet blade 220 has a tendency to pivot towards a first pivot position under its own weight, and can pivot from the first pivot position to a second pivot position under the push of the airflow blowing towards the air inlet 131. The pivot axis may, but is not limited to, be located at the top of the outlet blade 220 along a first direction, which is the opposite direction of gravity. See [reference needed] for details. Figure 8 The top end of the air outlet blade 220 along the first direction is provided with a hinge hole 221 that is hinged to the mounting window corresponding to the mounting bracket 211. The other end hangs down naturally to block the mounting window. The hinge hole 221 can be a structure with an axial groove on the side wall to facilitate the disassembly and assembly of the air outlet blade 220 from the grooved structure.

[0090] Specifically, when the blade assembly 200 is in the first state, if the pressure difference between the air inlet 131 and the air outlet 132 is less than a preset value, the blade assembly 200 can maintain its first state under its own weight, thus separating the air inlet 131 and the air outlet 132 of the air duct 130. When the blade assembly 200 is in the first state, if the pressure difference between the air inlet 131 and the air outlet 132 is greater than or equal to a preset value, the blade assembly 200 can switch from the first state to the second state under the impetus of air pressure or wind. When the wind force decreases until it disappears, the blade assembly 200 returns to the first state from the second state under its own gravity.

[0091] For example, Figure 4 and Figure 5 The diagram illustrates a technical solution where the blade assembly 200 adopts a self-hanging structure. When not subjected to wind force exceeding a preset value, the blade assembly 200 can maintain its first position by its own gravity, thus sealing the air duct 130 and meeting the IP55 protection level, ensuring long-term reliable operation of the equipment. When the wind force is sufficient to push the blade assembly 200, the blade assembly 200 is pushed and moved, connecting the air inlet 131 and the air outlet 132 of the air duct 130 for exhaust.

[0092] In another example, the blade assembly 200 is configured to have a tendency to maintain a first shape under the action of an elastic member: the blade assembly 200 also includes an elastic member disposed between the air outlet blade 220 and the window frame of the mounting window for providing an elastic force to the air outlet blade 220 to maintain it in a first swing position, and is able to swing from the first swing position to a second swing position under the action of the airflow blowing toward the air inlet 131.

[0093] Specifically, the elastic component can be a torsion spring installed between the swing shaft and the window frame of the installation window, or a spring, tension rope, or other elastic component connected between the air outlet blade 220 and the window frame of the installation window.

[0094] Taking the elastic element as a tension element as an example, when the blade assembly 200 is in the first state, if the pressure difference between the air inlet 131 and the air outlet 132 is less than a preset value, the blade assembly 200 can remain in the first state under the tension of the elastic element (not shown in the figure). When the blade assembly 200 is in the first state, if the pressure difference between the air inlet 131 and the air outlet 132 is greater than or equal to the preset value, the blade assembly 200 can switch from the first state to the second state under the pushing action of air pressure or wind force, and the elastic element deforms at the same time. When the wind force decreases until it disappears, the blade assembly 200 resets from the second state to the first state under the tension of the elastic element.

[0095] As another example, the blade assembly 200 can be maintained in the first position by the weight of the blade assembly 200 and the elastic force of the elastic element. In this case, the blade assembly 200 is configured to have a tendency to maintain the first position under the dual action of its own weight and the elastic element.

[0096] Taking the blade assembly 200 as an example when it is currently in the second state, if the airflow thrust in the air duct 130 is insufficient to overcome its own weight and / or the force of the elastic element, the blade assembly 200 will switch from the second state to the first state and remain in the first state.

[0097] By designing the air outlet assembly in this structural form, it can automatically switch between the first and second modes without requiring an additional drive mechanism. Of course, in practical applications, it can also be designed with a drive mechanism to operate, depending on actual needs; no specific limitations are made here.

[0098] In a further implementation scheme, the air outlet blades 220 on the blade assembly 200 can be made of lightweight materials such as aluminum alloy, which are lightweight, simple in structure, and easy to install and maintain. At the same time, when the fan in the cabinet starts and blows air into the air outlet assembly, the air outlet blades 220 are easily blown from the first swing position to the second swing position. When the fan stops, the air outlet blades 220 can fall down by gravity, while sealing the air duct 130 to prevent dust, rainwater, etc. from entering the cabinet. This design enables the blade assembly 200 to open and close by itself.

[0099] In some specific embodiments provided in this application, reference is made to Figure 4 and Figure 5 The air outlet duct includes at least two interconnected air outlet branches 251, with adjacent air outlet branches 251 arranged at an angle to make the overall air outlet duct curved, thus improving waterproof performance. Specifically, in actual use, the air outlet components are arranged in the direction shown in the figure, that is, each air outlet duct in the direction from the air outlet 132 to the air inlet 131 presents multiple upward-trending stepped structures, thereby effectively intercepting rainwater entering the air duct 130 from the air outlet 132, reducing the probability of rainwater entering the main body of equipment such as cabinets.

[0100] To allow the airflow entering through the air inlet 131 to flow along the various air outlet channels, a guide vane 240 can be installed at the air inlet 131, and the guide vane 240 is located within the air duct 130. One end of the guide vane 240 is connected to the air outlet body 100, and the other end extends to the air outlet channel to guide the airflow into the air outlet channel, allowing the airflow to finally be discharged upwards along the air outlet channel. Both the air duct plate 250 and the guide vane 240 can be fixed to the air outlet body 100 using screws, rivets, or other connecting parts for easy disassembly and maintenance.

[0101] To prevent water leakage at the connection between the air outlet unit 100 and the server rack, please refer to... Figure 3 The air outlet body 100 has a mounting surface 110, an air inlet 131 is disposed on the mounting surface 110, and a sealing element 300 is disposed on the mounting surface 110. During installation, the sealing element 300 is pressed tightly between the mounting surface 110 and the cabinet, serving a waterproof function and meeting the IP55 protection rating, thereby ensuring the long-term reliable operation of the equipment. The sealing element 300 can be adhered to the air outlet body 100 using adhesive, and a sealing groove can also be provided on the air outlet body 100 for the sealing element 300 to be embedded in.

[0102] Furthermore, to prevent the seal 300 from being over-compressed and causing seal failure, reinforcing ribs are provided on the mounting surface 110. The reinforcing ribs can enhance the structural strength of the air outlet body 100 and limit the compression of the seal 300. For example, the height of the reinforcing ribs can be half the initial thickness of the seal 300, and the reinforcing ribs can be installed on the mounting surface 110 by welding, riveting, screwing, or other methods.

[0103] To prevent external debris from entering the server rack, refer to Figure 2 A ventilation protection component 400 is installed at the air outlet 132 on the air outlet surface 120 of the air outlet body 100.

[0104] For example, the ventilation protection component 400 can be designed as a protective mesh panel, which can better prevent insects and other foreign objects from entering the air duct 130. The ventilation protection component 400 can be installed on the outside of the air outlet body 100 by means of screwing, snapping, or plugging, so as to facilitate disassembly and cleaning.

[0105] On the other hand, this application embodiment also provides a cabinet, which includes a cabinet body and the aforementioned air outlet assembly. The air outlet assembly is disposed in the cabinet body, for example, the air outlet assembly is used to be disposed on the side of the cabinet or on the side air outlet bend at the top of the cabinet, and the air inlet 131 is connected to the internal space of the cabinet body. The cabinet exhausts air and dissipates heat through the air outlet assembly. Specifically, mounting holes 111 are provided on the air outlet body 100, and the air outlet body 100 can be fixed to the cabinet by means of screwing, riveting, etc.
