[0046] The core of this application is to disclose an air intake component to improve the waterproof performance of the air intake component.

[0047] Another key aspect of this application is the disclosure of an electrical device that includes the aforementioned air intake components.

[0048] 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.

[0049] In related technologies, louvers are typically used as the air intake structure for ventilation and heat dissipation in electrical equipment. However, as the power level of electrical equipment increases, the power of fans gradually increases to meet the heat dissipation requirements of high-power devices, resulting in larger fan speeds and air volumes. The air intake area of ​​louvers is relatively small and cannot meet the air volume requirements. Furthermore, in outdoor applications, rainwater can easily enter the electrical equipment, posing a safety hazard. Therefore, this application discloses the following air intake component and electrical equipment.

[0050] Combination Figure 1 , Figure 4 and Figure 5 The air intake assembly disclosed in this application includes an air duct assembly 100 and a guide plate 200. The air duct assembly 100 is provided with an air intake duct 101, which has an air inlet 101a and an air outlet 101b. Vertically, the air inlet 101a is located below the air outlet 101b. When the air intake assembly is assembled on the cabinet 400 of the power equipment, the air outlet 101b communicates with the inner cavity of the cabinet 400. External airflow flows from the air inlet 101a to the air outlet 101b and then enters the inner cavity of the cabinet 400. There is at least one guide plate 200, which is disposed in the air intake duct 101. It is used to guide the airflow and also serves to block rain. Air inlet 101a is usually arranged facing the ground. The direction perpendicular to air inlet 101a is defined as the air intake direction. The air intake direction is usually parallel to the vertical direction or has a small angle. The following description takes the air intake direction being parallel to the vertical direction as an example. The guide plate 200 is arranged at an angle relative to the vertical direction. This angle is greater than 0° and not greater than 90°. This allows the airflow entering the air intake duct 101 from air inlet 101a to be adjusted to a certain extent under the action of the guide plate 200, and the airflow path is extended. At the same time, the guide plate 200 can block rainwater in the airflow, thereby effectively preventing rainwater from directly entering the cabinet 400 from air inlet 101a, and improving the waterproof rating of cabinet 400.

[0051] Combination Figure 6 , Figure 6The solid arrows in the diagram illustrate a scenario where rainwater is present in the external environment, and when the fans inside the cabinet 400 draw air for heat dissipation through the air intake components, some rainwater is drawn into the air intake duct 101 along with the airflow. Figure 6 The dashed arrows in the diagram illustrate a path in which rainwater is blocked by the deflector 200 within the air intake duct 101 and flows outward for discharge. The air intake assembly disclosed in this application, by providing the deflector 200 within the air intake duct 101, can effectively block and intercept most of the rainwater carried in the airflow, thereby improving the waterproofing effect.

[0052] Compared with related technologies, the air intake component disclosed in this application embodiment allows the airflow to flow along a curve in the air intake duct 101 through the setting of the guide plate 200, which can play a role in blocking rain and has good waterproof performance. In addition, the air intake component disclosed in this application embodiment also has the advantages of simple and compact structure, small size and large air intake volume.

[0053] Combination Figure 7 In some embodiments, the air inlet duct 101 includes a vertically connected air inlet section 101c and an air outlet section 101d. Vertically, the lower end of the air inlet section 101c is provided with an air inlet 101a, and the upper end of the air inlet section 101c is connected to the first end of the air outlet section 101d. The second end of the air outlet section 101d is provided with a horizontally discharging air outlet 101b. When air enters the cabinet 400 through the air inlet duct 101, the airflow flows from the air inlet section 101c to the air outlet section 101d, thus achieving a technical solution of vertical air intake at the bottom and horizontal air outlet at the top of the air inlet assembly. This allows for adjustment of the airflow direction within the air inlet duct 101, improving the rainproof effect. A guide plate 200 is disposed within the air inlet section 101c, and a second protective plate 320 is disposed within at least one of the air inlet section 101c and the air outlet section 101d.

[0054] The air duct assembly 100 includes a first enclosing plate 110 and a second enclosing plate 120, which are connected to form an air inlet duct 101. Figure 1 and Figure 10 In the first enclosure 110 and the second enclosure 120, the first enclosure 110 is used to be disposed between the second enclosure 120 and the cabinet 400, and the outer wall of the second enclosure 120 is used to shield the rainwater from the outside and directly intercept most of the rainwater outside the air intake duct 101.

[0055] In some embodiments, in the vertical direction, at least one first end of the guide plate 200 is higher than the second end of the guide plate 200, that is, combined with Figure 6The guide plate 200 is arranged at an angle relative to the vertical direction, so as to guide the rainwater blocked by the guide plate 200 through the angled arrangement of the guide plate 200, so that the rainwater can flow along the surface of the guide plate 200 from its first end to its second end, which facilitates subsequent discharge treatment.

[0056] Specifically, in some embodiments disclosed in this application, the second end of the guide plate 200 is positioned above the air inlet 101a and directly opposite it in the vertical direction. When the rainwater carried in the airflow is blocked by the guide plate 200, the rainwater can flow along the surface of the guide plate 200 from its first end to its second end. Finally, under the action of gravity, it can drip directly from the second end of the guide plate 200 to the air inlet 101a and flow out of the air inlet duct 101. The structure is simple and the waterproof effect is reliable.

[0057] In other embodiments disclosed in this application, a water collection trough 111 is provided at the bottom of the first enclosure plate 110. The water collection trough 111 has a drain outlet. Vertically, at least one first end of a guide plate 200 is higher than its second end, and the first end of the guide plate 200 is positioned above and directly opposite the air inlet 101a. The second end of the guide plate 200 is positioned above and directly opposite the water collection trough 111. Simultaneously, in the vertical plane, the water collection trough 111 and the air inlet 101a are staggered. When rainwater carried in the airflow is blocked by the guide plate 200, under the action of gravity, it can flow along the surface of the guide plate 200 from the first end to the second end, and drip from the second end of the guide plate 200 into the water collection trough 111. Finally, it is directly discharged or centrally treated through the drain outlet for convenient management of electrical equipment. For example, Figure 5 The diagram illustrates a technical solution in which the first end of each guide plate 200 is arranged opposite to the air inlet 101a along the vertical direction, and the second end of a portion of the guide plates 200 is arranged opposite to the water collection tank 111, while the second end of another portion of the guide plates 200 is arranged opposite to the air inlet 101a, so as to drain water simultaneously through the water collection tank 111 and the air inlet 101a.

[0058] Those skilled in the art will understand that, in combination Figure 6 Rainwater flowing along the outer wall of the second enclosure plate 120 to the air inlet 101a is more likely to flow towards the first enclosure plate 110 when subjected to wind force. Therefore, the guide plate 200 in the above embodiment is arranged closer to the first enclosure plate 110 and can guide the airflow towards the side where the second enclosure plate 120 is located, thereby improving the rainwater blocking effect.

[0059] In some embodiments, combined with Figure 8 The guide plates 200 are arranged horizontally. In the vertical direction, multiple guide plates 200 are arranged at intervals and are staggered and fixed on both sides of the air inlet duct 101 so as to divide the air inlet duct 101 into an S-shaped maze structure, thereby achieving a multi-level waterproof effect. The specific number of guide plates 200 is not limited in this embodiment.

[0060] To prevent foreign objects, insects, etc. from entering the rack 400, combined with Figure 2 and Figure 3 The air intake assembly also includes a protective assembly 300, which includes a first protective plate 310. The first protective plate 310 is located at the air inlet 101a and is arranged at an angle relative to the vertical direction. A filter mesh is formed on the first protective plate 310 to filter the airflow entering the air intake duct 101 from the air inlet 101a, thereby achieving safety protection for the interior of the cabinet 400. The first protective plate 310 can be a wire mesh, dustproof mesh, etc., with a simple structure, easy maintenance, and low cost. The above-mentioned drainage solution using a water collection tank 111, with the water collection tank 111 staggered from the air inlet 101a, effectively reduces the accumulation of dust and debris on the surface of the first protective plate 310, preventing it from mixing with rainwater and causing blockage of the air inlet 101a. This ensures the heat dissipation effect of the cabinet 400 and the normal operation of the components inside the cabinet 400.

[0061] In some embodiments, combined with Figure 2 and Figure 3 The first end of the first protective plate 310 is connected to the mounting bracket 130, which in turn is connected to the first enclosing plate 110. The second end of the first protective plate 310 is connected to the second enclosing plate 120. Specifically, the connection can be made directly by abutting against the first plate or through a connector. The mounting bracket 130 facilitates the positioning and installation of the first protective plate 310 with the irregularly shaped first enclosing plate 110. The mounting bracket 130 and the first enclosing plate 110 can be connected using screws, bolts, spring plungers, or other connectors, allowing for flexible arrangement.

[0062] The first protective plate 310 can be installed inside or outside the air inlet duct 101. Installing the first protective plate 310 outside the air inlet duct 101 facilitates assembly, while installing the first protective plate 310 inside the air inlet duct 101 reduces the adhesion of dust and other impurities to the surface, thereby reducing the maintenance frequency.

[0063] The first protective plate 310 can be arranged at an angle or parallel to the horizontal direction. An angled arrangement of the first protective plate 310 helps prevent dust accumulation, avoiding increased ventilation resistance and decreased filtration efficiency caused by excessive dust accumulation. It also facilitates the maintenance and cleaning of the first protective plate 310. Furthermore, the angled arrangement of the first protective plate 310 can improve the ventilation performance of the air inlet duct 101, reducing airflow resistance as it passes over the wire mesh plate, making it easier for air to pass through and thus improving heat dissipation efficiency. Combined with... Figure 7 The first protective plate 310 is arranged in parallel with the horizontal direction, which is simple in structure and easy to assemble.

[0064] In some embodiments, the second end of the first protective plate 310 is closer to the second enclosure plate 120 than the first end of the first protective plate 310. Vertically, the first end of the first protective plate 310 may be lower than the second end of the first protective plate 310. This inclined arrangement of the first protective plate 310 prevents rainwater from directly contacting the second end of the first protective plate 310 and flowing along its surface when rainwater flows down the outer wall of the second enclosure plate 120. This significantly reduces the risk of water entering the cabinet 400 and effectively reduces the probability of adhesion and blockage on the surface of the first protective plate 310. For example, in combination with… Figure 5 The angle α between the first protective plate 310 and the vertical direction can be set to 85° or other angles, and the distance between the second end of the first protective plate 310 and the air inlet 101a can be set to 30mm or other lengths.

[0065] Since the first protective plate 310 requires frequent maintenance, it can be detachably installed at the air inlet 101a, allowing it to be directly installed and removed from outside the cabinet 400, thus improving maintenance efficiency and reducing maintenance costs. Specifically, the detachable connection methods between the first protective plate 310 and the air duct assembly 100 include, but are not limited to, screw connection, snap-fit ​​connection, plug connection, and pin connection.

[0066] In some embodiments, the first protective plate 310 is detachably connected to the mounting bracket 130 via a first connector 311, and detachably connected to the second enclosure plate 120 via a second connector 312. The first connector 311 may include at least one of a spring plunger, a screw, and a bolt, and the second connector 312 may also include at least one of a spring plunger, a screw, and a bolt. Using a spring plunger for fixing allows for screwless operation during on-site maintenance, improving maintenance convenience; using screws or bolts for fixing improves the reliability of the connection between the first protective plate 310 and the mounting bracket 130. Different connection methods can be used for different scenarios. For example, the first protective plate 310 may simultaneously have plunger holes for installing spring plungers and connection holes for installing bolts or screws. During the transportation of the air intake assembly, the first protective plate 310 can be fixed with screws or bolts through the connection holes to ensure reliable transportation of the air intake assembly. When the air intake assembly is actually installed and used in the cabinet 400, fixing with only spring plungers is sufficient to meet the usage requirements, and it is convenient to disassemble and assemble, and easy to maintain. This application does not limit the number or position of the first connector 311 and the second connector 312.

[0067] Combination Figure 5 The diagram illustrates a technical solution where a first protective plate 310 is arranged at an angle relative to the vertical direction, and a first connecting member 311 includes a spring plunger, and a second connecting member 312 includes a bolt. The bolt is threaded into a second enclosing plate 120. A slotted through hole is provided on the first protective plate 310 for the bolt to pass through as a connection hole. When the first protective plate 310 needs to be cleaned or replaced, the spring plunger is first pulled out to separate the first protective plate 310 from the mounting bracket 130. Then, the first end of the first protective plate 310 is moved toward the air inlet 101a, while the second end of the first protective plate 310 is moved away from the air inlet 101a through the slotted through hole, that is, the first protective plate 310 is moved around... Figure 5 Rotate counterclockwise and move the first end of the first protective plate 310 out of the air inlet duct 101. Finally, the first protective plate 310 can be removed from the bolt and taken out of the air inlet duct 101 as a whole for maintenance. The operation is simple and the maintenance is convenient. After the maintenance is completed, the first protective plate 310 can be reinstalled on the air duct assembly 100 by reversing the above steps. This will not be described again here.

[0068] In some embodiments, mounting rails can be provided on the air duct assembly 100, or on the first enclosure plate 110 and the second enclosure plate 120. The two sides of the first protective plate 310 are slidably mounted on the two mounting rails respectively. Figure 9 , Figure 9The arrows in the diagram indicate the direction in which the first protective plate 310 can be pulled out. The first protective plate 310 can be disassembled and assembled by pulling it out along the extension direction of the mounting rail without removing the screws, making the maintenance process efficient and convenient.

[0069] To further improve the protective effect of the air intake assembly, the protective assembly 300 may also include a second protective plate 320. The second protective plate 320 is disposed within the air intake duct 101 and has filter mesh openings for filtering foreign objects in the air, thereby enhancing protection. Specifically, in the vertical direction, the second protective plate 320 is higher than the guide plate 200, that is, the second protective plate 320 is further away from the air inlet 101a than the guide plate 200, to avoid interference with the guide plate 200. At the same time, after the guide plate 200 blocks rainwater, the amount of rainwater carried in the airflow is greatly reduced, thus effectively reducing the frequency of maintenance caused by the second protective plate 320 being stuck and blocked. The number of second protective plates 320 is at least one. When the air intake assembly includes multiple second protective plates 320, each second protective plate 320 is arranged sequentially at different positions within the air intake duct 101 along the extension direction of the air intake duct 101 to form multiple filtrations of the airflow, ensuring the protective effect. The second protective plate 320 and the first protective plate 310 may adopt the same or different structures, and this application embodiment does not limit this. For example, both the first protective plate 310 and the second protective plate 320 include a wire mesh plate, and the size of the filter mesh holes on the second protective plate 320 is smaller than the size of the filter mesh holes on the first protective plate 310 to improve the filtration effect; in addition, the second protective plate 320 may also include dustproof cotton, and the dustproof effect is achieved through the dustproof cotton. Furthermore, the arrangement of the guide plate 200 reduces the flow of rainwater at the second protective plate 320, reduces the adhesion and clogging of the dustproof cotton, and ensures the protective effect of the dustproof cotton. The second protective plate 320 and the first protective plate 310 can be connected and fixed to the air duct assembly 100 in the same or different ways, and this application embodiment does not limit this. Figure 2 It shows a technical solution in which the second protective plate 320 is fixed to the first enclosure plate 110 by screws through the mounting bracket 130.

[0070] The guide vane 200 can be fixed inside the air inlet duct 101 in various ways. For example, the guide vane 200 can be fixed to the second protective plate 320, directly connected to the duct assembly 100, or connected to the duct assembly 100 via the mounting bracket 130, as long as it does not affect the disassembly and maintenance of the first protective plate 310. The arrangement is flexible. For example, combined with... Figure 5 It illustrates a technical solution for connecting the deflector 200 and the second protective plate 320; combined with Figure 8 It shows a technical solution in which multiple guide plates 200 are respectively connected to the second enclosure plate 120 and the mounting bracket 130.

[0071] The air intake component disclosed in this application, after being assembled onto the cabinet 400, protrudes only about 12cm from the main frame of the cabinet 400, effectively preventing external rainwater from directly entering the cabinet 400, and achieving a waterproof rating of IPX5, ensuring the normal and stable operation of the power equipment in heavy rain environments. Compared with traditional louvers, the air intake area of ​​the air intake component disclosed in this application can be increased by 66.37% or even more for the same size, improving the heat dissipation effect of the power equipment. In addition, the air intake component disclosed in this application also has the advantages of fewer parts, compact structure, small space occupation, convenient production and assembly, and light overall weight.

[0072] Combination Figure 10 and Figure 11 The power equipment disclosed in this application includes a cabinet 400 and the aforementioned air intake component. The air intake component is located outside the cabinet 400 and connected to the cabinet 400. The air intake duct 101 communicates with the inner cavity of the cabinet 400, preventing the air intake component from affecting the internal components of the cabinet 400 during maintenance and enabling uninterrupted maintenance of the air intake component without shutting down or interrupting power. Since it includes the aforementioned air intake component, it also possesses the aforementioned structure and beneficial effects. Other structures can refer to existing technologies and will not be elaborated here. For example, this power equipment can specifically be an energy storage converter, a photovoltaic distribution cabinet, etc. At least one of the first enclosure plate 110 and the second enclosure plate 120 of the air intake component is connected to the cabinet 400, typically using screws or similar methods for easy disassembly and maintenance. Figure 1 and Figure 11 It shows a technical solution in which a connection hole 121 is opened on the second enclosure plate 120, and the connector is screwed to the cabinet 400 through the connection hole 121.

[0073] The terms "first" and "second," etc., used in the specification and claims of this application are used to distinguish different objects, not to describe a specific order, and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.
