Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, and more specifically, to a rain cover, a fan device, and a cabinet air conditioner having the same. Background Technology

[0002] In environments such as communication base stations and industrial control rooms, rack air conditioners are key equipment responsible for maintaining suitable temperature conditions inside the rack to ensure stable operation of the equipment. External circulation fans, as an important component of rack air conditioners, are responsible for introducing external air into the unit for heat exchange, thereby achieving the function of heat dissipation and cooling.

[0003] However, outdoor cabinet air conditioners often face the risk of rain intrusion. Rainwater intrusion may not only cause short circuits and reduced insulation performance in the internal circuit of the fan, but may also cause corrosion problems, which seriously affect the service life and performance stability of the fan, thereby affecting the normal operation of the cabinet air conditioner and the stability of the overall system.

[0004] Currently, the methods for rain protection of external circulation fans in rack-mounted air conditioners typically involve using high-water-resistance fans, applying adhesive to the motor, and adding rain covers. Among these methods, high-water-resistance motors are relatively expensive, increasing costs, and it is difficult to find a motor with a waterproof rating that fully meets the requirements. Applying adhesive to the motor can lead to poor fan heat dissipation, increasing the fan's power consumption. Moreover, in extreme weather conditions such as continuous rainfall, there is still a safety hazard of water ingress and burnout of the fan. Furthermore, the existing rain covers' shape, size, and other design factors cannot fully consider the airflow characteristics, resulting in excessive wind resistance and affecting the overall heat dissipation of the unit. Summary of the Invention

[0005] The main objective of this invention is to provide a rain cover, a fan device, and a cabinet air conditioner having the same, in order to solve the problem in the prior art that rainwater can easily enter the fan and burn out the motor inside the fan.

[0006] To achieve the above objectives, according to one aspect of the present invention, a rain cover, a fan device, and a cabinet air conditioner having the same are provided.

[0007] According to another aspect of the present invention, a rain cover is provided, comprising: a support structure for mounting on a support base;

[0008] The first rainproof structure is located on the supporting structure;

[0009] The first rainproof structure includes a plurality of first rainproof components arranged sequentially along a first direction. Each first rainproof component is arranged around a predetermined center line. Along the first direction, the outer periphery of each first rainproof component extends in a direction that gradually moves away from the predetermined center line. A preset flow gap for airflow is formed between each pair of adjacent first rainproof components.

[0010] Along the first direction, each first rainproof component includes a first edge and a second edge. In two adjacent first rainproof components along the first direction, the first edge of the first rainproof component is located inside the annular surface on which the outer peripheral surface of the second rainproof component is located.

[0011] Furthermore, the rain cover also includes: a second rainproof structure disposed inside the first rainproof structure, the second rainproof structure having a second rainproof component for covering the part to be protected from rain.

[0012] Furthermore, the second rainproof structure also includes:

[0013] The third rainproof component has one end connected to the first rainproof structure and the other end connected to the second rainproof component.

[0014] Furthermore, the third rainproof component is a cylindrical or rod-shaped structure; and / or,

[0015] The third rainproof component has a connecting flange at the end furthest from the second rainproof component. The first rainproof structure has multiple first fixing posts, so that the connection between the second rainproof structure and the first rainproof structure can be achieved by first fastening components passing through the connecting flange and each of the first fixing posts.

[0016] Furthermore, the second rainproof component is arranged around the predetermined center line, and along the first direction, the outer periphery of the second rainproof component extends in a direction that gradually moves away from the predetermined center line;

[0017] The outer circumferential surface of the second rainproof component is annular with a diameter of d3, and the outer circumferential surface of the part to be rainproofed is cylindrical with a diameter of d4, wherein d3 > d4 + 20 mm; and / or,

[0018] The rain cover is used to cover the outside of the fan, and the part to be protected from rain is the fan motor.

[0019] Furthermore, the first rainproof structure includes:

[0020] A connecting assembly is connected to multiple first rainproof components, so that the multiple first rainproof components are relatively fixed by the connecting assembly.

[0021] Furthermore, multiple first rainproof components are arranged relatively independently, and each first rainproof component is fixedly connected to the connecting assembly; or,

[0022] Multiple primary rainproof components and connecting assemblies are integrally molded.

[0023] Furthermore, the supporting structure also includes:

[0024] A support assembly, one end of which is connected to at least one of a plurality of first rainproof components, and the other end of which is used to connect to a support base.

[0025] Furthermore, the supporting components include:

[0026] Multiple support brackets are arranged around a predetermined center line; multiple second fixed columns are provided on the first rainproof structure, and the multiple second fixed columns are arranged one-to-one with the multiple support brackets, so that the support brackets are connected to the first rainproof structure by second fastening components passing through each support bracket and the corresponding second fixed column.

[0027] Furthermore, the support bracket includes two fixed plates arranged opposite each other and a connecting plate connecting the two fixed plates. One fixed plate is connected to a corresponding second fixed column through a second fastening component, and the other fixed plate is connected to the support foundation through a third fastening component.

[0028] Furthermore, in each second rainproof component, both the first edge and the second edge are circular, and the diameter of the first edge is smaller than the diameter of the second edge;

[0029] Among the two adjacent first rainproof components along the first direction, the diameter d5 of the second edge of the first first rainproof component is greater than the diameter d6 of the first edge of the second first rainproof component.

[0030] Furthermore, the difference between the diameter d1 of the second edge of the first rainproof component at the very end and the diameter d2 of the housing to be rainproofed is 50mm, wherein the housing to be rainproofed is the outer shell of the fan.

[0031] Furthermore, the outer peripheral surfaces of multiple first rainproof components together form a conical rain-guiding surface.

[0032] According to another aspect of this application, a fan device is also provided, including a fan assembly, a supporting foundation disposed on the fan assembly, and the fan device further including a rain cover as described above, the rain cover being disposed on the supporting foundation.

[0033] Furthermore, the fan assembly includes a fan and a fan housing disposed on the outside of the fan, and the supporting foundation consists of a plurality of lugs disposed on the fan housing and protruding toward the outside of the fan housing.

[0034] According to another aspect of this application, a cabinet air conditioner is also provided, including a cabinet and a fan device as described above, the fan device being disposed on the cabinet.

[0035] When rainwater falls, it slides down the multiple first rainproof components in sequence and from the second edge of the lowest first rainproof component. During the entire flow process, the rainwater will not enter the inside of the fan assembly due to the existence of the preset flow gap. Because of the size relationship between the diameter of the first edge and the diameter of the second edge, the rainwater will not enter the inside of the fan assembly.

[0036] The rain cover in this application, through the conical structure design of multiple first rainproof components, effectively intercepts rainwater falling from above. As rainwater flows past these first rainproof components, it is guided downwards along their outer surfaces, rather than directly entering the fan assembly. This structure ensures that rainwater does not directly contact the fan or circuitry of the fan assembly, significantly improving electrical safety and reliability, and avoiding risks such as short circuits, reduced insulation performance, or burnout caused by rainwater intrusion. The design of the first edge diameter of the first rainproof component being smaller than the second edge diameter, along with the pre-set flow gaps formed between the first rainproof components, allows airflow without significantly increasing wind resistance. This design ensures that the external circulation fan of the cabinet air conditioner maintains good ventilation and heat dissipation efficiency, maintaining overall operational stability even under the rain cover's protection, reducing power consumption, and improving energy efficiency. The rain cover's structure not only provides initial waterproofing (primary waterproofing) but also, through the layered protection of multiple first rainproof components, forms further waterproofing (secondary waterproofing). Even under extreme weather conditions, such as continuous rainfall, the multi-layered design of the rain cover prevents rainwater from entering from the sides, providing comprehensive protection and ensuring the long-term stable operation of the wind turbine components. The installation method of the rain cover (connected to the wind turbine components via a support structure) and the arrangement of multiple first rainproof components can adapt to wind turbine components of different diameters and environmental conditions with varying wind speeds and rainfall, increasing the rain cover's applicability and scenario adaptability. Fixing the first rainproof structure to the wind turbine components via the support structure simplifies the installation process and facilitates daily maintenance and inspection. Furthermore, the pre-designed flow gaps facilitate cleaning and maintenance, preventing dust and debris accumulation and further improving system efficiency and safety. This application's rain cover, through optimized structural design, avoids the use of expensive, high-waterproof-rating wind turbines or the potting of wind turbine motors, thereby reducing costs and improving economic efficiency while ensuring waterproof performance.

[0048] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0049] In environments such as communication base stations and industrial control rooms, rack air conditioners are key equipment responsible for maintaining suitable temperature conditions inside the rack to ensure stable operation of the equipment. External circulation fans, as an important component of rack air conditioners, are responsible for introducing external air into the unit for heat exchange, thereby achieving the function of heat dissipation and cooling.

[0050] However, outdoor cabinet air conditioners often face the risk of rain intrusion. Rainwater intrusion may not only cause short circuits and reduced insulation performance in the internal circuit of the fan, but may also cause corrosion problems, which seriously affect the service life and performance stability of the fan, thereby affecting the normal operation of the cabinet air conditioner and the stability of the overall system.

[0051] Currently, the methods for rain protection of external circulation fans in rack-mounted air conditioners typically involve using high-water-resistance fans, applying adhesive to the motor, and adding rain covers. Among these methods, high-water-resistance motors are relatively expensive, increasing costs, and it is difficult to find a motor with a waterproof rating that fully meets the requirements. Applying adhesive to the motor can lead to poor fan heat dissipation, increasing the fan's power consumption. Moreover, in extreme weather conditions such as continuous rainfall, there is still a safety hazard of water ingress and burnout of the fan. Furthermore, the existing rain covers' shape, size, and other design factors cannot fully consider the airflow characteristics, resulting in excessive wind resistance and affecting the overall heat dissipation of the unit.

[0052] Therefore, the purpose of this application is to provide a rain cover, a fan unit, and a cabinet air conditioner having the above-mentioned problems.

[0053] First, this application provides a rain cover, including a support structure 1, which is used to be installed on a support base;

[0054] First rainproof structure 2, the first rainproof structure 2 is provided on the support structure 1;

[0055] The first rainproof structure 2 includes a plurality of first rainproof components 201 arranged sequentially along a first direction. Each first rainproof component 201 is arranged around a predetermined center line. Along the first direction, the outer periphery of each first rainproof component 201 extends in a direction that gradually moves away from the predetermined center line. A preset flow gap for airflow is formed between each two adjacent first rainproof components 201.

[0056] Along the first direction, each first rainproof component 201 includes a first edge and a second edge. In two adjacent first rainproof components 201 along the first direction, the first edge of the first first rainproof component 201 is located inside the annular surface on which the outer peripheral surface of the second first rainproof component 201 is located.

[0057] First, this application provides a rain cover, such as Figure 1 , Figure 2 As shown, the rain cover of this application can be mounted on a supporting foundation, which is a structure on the fan assembly 9. The relationship between the two will be explained in subsequent embodiments. The rain cover includes a supporting structure 1 connected to the supporting foundation, and also includes a first rainproof structure 2 mounted on the supporting structure 1. The first rainproof structure 2 includes a plurality of first rainproof components 201, which are arranged sequentially along a first direction. Figure 1In the vertical direction, each first rainproof component 201 is arranged around a predetermined center line. Along the first direction, the outer periphery of each first rainproof component 201 extends gradually away from the predetermined center line. That is, each first rainproof component 201 has a conical structure. The predetermined center line is the central axis of each first rainproof component 201. Along the first direction, each first rainproof component 201 has a first edge and a second edge. The diameter of the first edge of each first rainproof component 201 is smaller than the diameter of the second edge. In any two adjacent first rainproof components 201, the first edge of the first first rainproof component 201 is located inside the annular surface on which the outer periphery of the second first rainproof component 201 is located. Furthermore, a predetermined flow gap for airflow is formed between each two adjacent first rainproof components 201.

[0058] In the application process, such as Figure 5 and Figure 6 As shown, when rainwater falls, it slides down the multiple first rainproof components 201 in sequence and from the second edge of the lowest first rainproof component 201. During the entire flow process, the rainwater will not enter the fan assembly 9 due to the existence of the preset flow gap, because each first rainproof component 201 has a conical structure, and at the same time, due to the size relationship between the diameter of the first edge and the diameter of the second edge, the rainwater will not enter the fan assembly 9.

[0059] like Figures 1 to 8As shown, the rain cover in this application, through the conical structure design of multiple first rainproof components 201, can effectively intercept rainwater falling from above. When rainwater flows through these first rainproof components 201, it is guided to flow downwards along their outer surfaces, rather than directly entering the interior of the fan assembly 9. This structure ensures that rainwater does not directly contact the fan 5 or circuit components of the fan assembly 9, significantly improving the reliability of electrical safety and avoiding risks such as short circuits, decreased insulation performance, or burnout caused by rainwater intrusion. The design that the diameter of the first edge of the first rainproof component 201 is smaller than the diameter of the second edge, and the preset flow gap formed between each first rainproof component 201, allows airflow to pass through without causing a significant increase in wind resistance. This design ensures that the external circulation fan of the cabinet air conditioner can maintain good ventilation and heat dissipation efficiency, and even under the action of the rain cover, it can maintain the operational stability of the entire unit, reduce power consumption, and improve energy efficiency. The structure of the rain cover not only provides initial waterproofing, but also forms further secondary waterproofing through the layered protection of multiple first rainproof components 201. Even under extreme weather conditions, such as continuous rainfall, the multi-layered design of the rain cover prevents rainwater from entering from the sides, providing comprehensive protection and ensuring the long-term stable operation of the wind turbine assembly 9. The installation method of the rain cover, connecting it to the wind turbine assembly 9 via a support structure, and the arrangement of multiple first rainproof components 201, can adapt to wind turbine assemblies 9 of different diameters and environmental conditions with varying wind speeds and rainfall, increasing the rain cover's applicability and scenario adaptability. The first rainproof structure 2 is fixed to the wind turbine assembly 9 via the support structure 1, simplifying the installation process and facilitating daily maintenance and inspection. Furthermore, the pre-designed flow gap facilitates cleaning and maintenance, preventing dust and debris accumulation, further improving system efficiency and safety. Through optimized structural design, the rain cover of this application avoids the use of expensive, high-waterproof-rating wind turbines or the potting of the wind turbine motor, thereby ensuring waterproof performance while reducing costs and improving economic efficiency.

[0060] Furthermore, the rain cover also includes a second rainproof structure 3, which is disposed inside the first rainproof structure 2, and the second rainproof structure 3 has a second rainproof component 301 for covering the part 4 to be protected from rain.

[0061] Specifically, if Figures 1 to 8 As shown, the rain cover also includes a second rain cover 3 disposed inside the first rain cover 2. The second rain cover 3 has a second rain cover component 301 that can be covered on the part to be protected from rain 4. The second rain cover component 301 has a conical design and the large diameter end of the second rain cover component 301 faces the part to be protected from rain 4.

[0062] The addition of the second rainproof structure 3 in this application not only protects the fan assembly 9 from direct rainwater intrusion, but more importantly, it forms a secondary waterproof protection layer for the rainproof part 4 (and the motor in the fan assembly 9). The rainproof part 4 is located inside the support foundation, and in this embodiment, the rainproof part 4 refers to the motor of the fan 5. Even if the first rainproof component 201 fails to completely block rainwater and rainwater enters the support foundation, the second rainproof component 301 can effectively intercept it, preventing the rainwater entering the support foundation from entering the rainproof part 4, greatly improving the electrical safety and reliability of the overall system. By combining the second rainproof structure 3 with multiple first rainproof components 201, wind resistance can be effectively adjusted, ensuring that while providing rain protection, airflow can smoothly pass through the first rainproof structure, reducing wind resistance, improving the ventilation and heat dissipation efficiency of the fan assembly 9, thereby ensuring the overall operational stability and energy efficiency of the cabinet air conditioner. The design of the second rainproof component 301 can adapt to support foundations of different sizes. By adjusting the size of the cavity formed by the large-diameter end of the second rainproof component 301, it can be used with different models of wind turbines 5, improving the versatility and adaptability of the rainproof cover. The structural design of the second rainproof structure 3 allows for quick connection with the first rainproof component 201 and the support foundation, simplifying the installation process. At the same time, its easy disassembly facilitates daily maintenance, such as cleaning accumulated water or dust from the rainproof components, maintaining good operating condition.

[0063] Furthermore, the second rainproof structure 3 also includes a third rainproof component 302, one end of which is used to connect with the first rainproof structure 2, and the other end of which is connected with the second rainproof component 301.

[0064] Furthermore, the third rainproof component 302 is a cylindrical structure or a rod structure; and / or,

[0065] A connecting flange 303 is provided at the end of the third rainproof component 302 that is away from the second rainproof component 301. A plurality of first fixing posts 202 are provided on the first rainproof structure 2 so that the connection between the second rainproof structure 3 and the first rainproof structure 2 is realized by first fastening components passing through the connecting flange 303 and each of the first fixing posts 202.

[0066] Specifically, the third rainproof component 302 can be a cylindrical structure or a rod structure, depending on the specific application scenario and rainproof requirements. Regardless of whether it is a cylindrical or rod structure, the third rainproof component 302 should have sufficient strength and stability to support the second rainproof component 301 without affecting its waterproof and ventilation performance. A connecting flange 303 is provided at the end of the third rainproof component 302 furthest from the second rainproof component 301. Its design aims to provide a stable connection point for connection with the first fixing post 202 on the first rainproof structure 2. The connecting flange 303 has holes corresponding to the first fixing post 202, providing precise guidance for the insertion of the first fastening component, which in this embodiment is the first fastening bolt. Multiple first fixing posts 202 are provided on the first rainproof structure 2. The distribution and position of these first fixing posts 202 need to be precisely designed according to the size and shape of the connecting flange 303 to ensure a stable and uniform connection between the second rainproof structure 3 and the first rainproof structure 2, avoiding structural damage or loosening caused by excessive local stress. The first fastening component (such as bolts, screws, etc.) is used to connect the second rainproof structure 3 and the first rainproof structure 2. By passing through the first fastening component in the connecting flange 303 and each of the first fixing posts 202, a tight connection of the rainproof structure is ensured, improving the installation accuracy and structural strength of the rainproof cover.

[0067] The cylindrical or rod-shaped structure of the third rainproof component 302, along with the cooperation of the connecting flange 303 and the first fixing post 202, significantly enhances the structural stability of the rain cover. This design effectively supports the second rainproof component 301, resisting the effects of severe weather conditions (such as strong winds and heavy rain) on the rain cover, ensuring its stability and durability in various environments. The combination of the connecting flange 303 and the first fixing post 202, along with the use of the first fastening component, simplifies the installation and disassembly of the rain cover. This not only improves installation efficiency but also facilitates maintenance and inspection, such as cleaning the interior of the rain cover or replacing damaged parts, without requiring complex tools or processes, thus reducing maintenance costs and time. The introduction of the third rainproof component 302, combined with the robust connection between the connecting flange 303 and the first fixing post 202, further optimizes the waterproof performance of the rain cover. Simultaneously, this design ensures unobstructed ventilation paths, reduces wind resistance, maintains the ventilation and heat dissipation efficiency of the fan, and achieves a balance between waterproofing and ventilation. The cylindrical or rod-shaped structure of the third rainproof component 302, along with the use of the connecting flange 303, allows the rain cover to adapt to fans and mating components of different sizes and shapes. This design flexibility improves the adaptability and versatility of the rain cover, making it suitable for a wider range of applications. The standardized design of the third rainproof component 302 and the use of the first fastening component reduce the manufacturing and installation costs of the rain cover. By reducing the need for special materials or complex installation tools, an economical and effective rainproof solution is achieved. The robust connection mechanism and optimized waterproof design improve the safety and reliability of the cabinet air conditioning system in outdoor environments. The addition of the third rainproof component 302 effectively prevents rainwater from entering the circuitry and motors, reducing the risk of electrical short circuits and equipment failure.

[0068] Furthermore, the second rainproof component 301 is arranged around the predetermined center line, and along the first direction, the outer periphery of the second rainproof component 301 extends in a direction that gradually moves away from the predetermined center line;

[0069] The outer peripheral surface of the second rainproof component 301 is annular with a diameter of d3, and the outer peripheral surface of the rainproof part 4 is cylindrical with a diameter of d4, wherein d3 > d4 + 20 mm; and / or,

[0070] The rain cover is used to cover the outside of the fan 5, and the rain-protected part 4 is the motor of the fan 5.

[0071] Specifically, the second rainproof component 301 is arranged around a predetermined centerline, and its outer periphery gradually moves away from the predetermined centerline along a first direction (usually vertical). This design ensures that the second rainproof component 301 can form a natural inclined surface, which helps rainwater to flow smoothly down its surface and prevents rainwater from directly entering the motor. The dimensions and structure of the second rainproof component 301: The outer periphery of the second rainproof component 301 is annular, and its diameter d3 is designed to be at least 20mm larger than the outer periphery diameter d4 of the part to be protected from rain (i.e., the motor of the fan 5). This design not only provides sufficient protection for the motor, preventing direct splashing of rainwater, but also leaves enough space to ensure that the motor's ventilation and heat dissipation are not affected. The rain cover is designed to cover the outside of the fan 5, wherein the second rainproof component 301 and the third rainproof component 302 are connected by a connecting flange 303, a first fixing post 202, and a first fastening component. This connection method ensures the stability and sealing of the rain cover, thereby more effectively preventing rainwater from entering the motor. Both the second rainproof component 301 and the third rainproof component 302 are made of corrosion-resistant, high-strength, and lightweight materials, such as aluminum alloy or polycarbonate, to ensure the durability and portability of the rain cover. During manufacturing, the dimensional accuracy of each component must be ensured to achieve good waterproofing and ventilation performance.

[0072] The natural tilt design of the second rainproof component 301 along the first direction, along with the optimized selection of its diameter d3 (greater than d4 + 20mm), significantly improves the waterproof performance of the rainproof cover, effectively preventing rainwater from entering the motor, avoiding electrical short circuits and equipment corrosion, and enhancing the electrical safety and mechanical reliability of the system. The space reserved between the second rainproof component 301 and the motor ensures good ventilation and heat dissipation for the motor, reducing wind resistance and improving ventilation efficiency, thereby maintaining the operational stability and efficiency of the fan 5 and extending the equipment's service life. The connection between the second rainproof component 301 and the third rainproof component 302 via the connecting flange 303 to the first fixed column 202 and the first fastening component not only improves the structural stability of the rainproof cover but also simplifies the installation and maintenance process, reducing installation costs and time. The tapered design of the second rainproof component 301, and the optimized ratio between its diameter d3 and the motor diameter d4, allows the rainproof cover to adapt to fan motors of different sizes and structures, improving its adaptability and versatility, and making it suitable for a wider range of applications. Compared to costly rainproofing methods such as using high-waterproof motors or motor potting, the rain cover solution in this embodiment provides efficient rainproofing while optimizing cost-effectiveness, reducing manufacturing and maintenance costs. The combined use of the second rainproof component 301 and the third rainproof component 302 improves the overall waterproof performance of the rain cover, while optimizing the ventilation path, ensuring the safe and stable operation of the fan 5 in various environments, and providing dual protection against rain and ensuring performance stability.

[0073] Furthermore, the first rainproof structure 2 includes:

[0074] The connecting component 6 is connected to multiple first rainproof components 201 so that the multiple first rainproof components 201 are relatively fixed by the connecting component 6.

[0075] Specifically, the connecting component 6 includes a plurality of support rods 601, and the two ends of each support rod 601 are respectively connected to the first and last two first rainproof components 201 among the plurality of first rainproof components 201.

[0076] Specifically, multiple support rods 601 of the connecting assembly 6 are evenly distributed at a certain angle and spacing, connecting the first and last components of the multiple first rainproof components 201 to form a stable frame structure. This layout ensures the balance and stability of the rain cover in all directions, effectively resisting external wind and rain impacts. The two ends of the support rods 601 are tightly connected to corresponding parts of the first rainproof components 201 by bolts. The support rods 601 are made of high-strength and corrosion-resistant materials, such as stainless steel or high-strength aluminum alloy, to ensure the durability and lightweight of the connecting assembly 6, meeting the needs of the rain cover in outdoor environments. The length and position of the support rods 601 need to be precisely designed according to the overall layout and diameter differences of the first rainproof components 201. Each support rod 601 should ensure that it does not interfere with the normal flow of air, while effectively supporting the first rainproof components 201 and preventing deformation or loosening under wind or rain. During manufacturing, it is necessary to ensure that the connection between the support rods 601 and the first rainproof components 201 has sufficient strength, while also considering rust prevention and anti-electrolytic corrosion treatment. During installation, the support rod 601 should be aligned with the connection point of the first rainproof component 201 and fixed with fasteners to ensure the overall sealing and waterproof performance of the rainproof cover.

[0077] The introduction of connecting components 6 (multiple support rods 601) significantly enhances the structural stability and overall durability of the rain cover. The layout and connection method of the support rods 601 effectively disperses and resists external impacts, ensuring the stability and safety of the rain cover under harsh weather conditions. The design of connecting components 6 considers the ventilation requirements of the rain cover, avoiding airflow obstruction by the support rods 601, reducing wind resistance, and ensuring that the efficiency and stability of the fan operation are not affected. This design achieves a balance between waterproofing and ventilation. The use of connecting components 6, especially the detachable connection between the support rods 601 and the first rainproof component 201, simplifies the installation and maintenance process of the rain cover. If the first rainproof component 201 needs to be replaced or cleaned, only the corresponding support rod 601 needs to be removed, without completely disassembling the rain cover, reducing maintenance costs and time. The design of connecting components 6 allows the rain cover to adapt to first rainproof components 201 of different sizes and layouts, improving the versatility and adaptability of the rain cover, suitable for the protection needs of various cabinet air conditioning fans. The standardized design and detachable connection of the support rod 601 reduce the manufacturing and installation costs of the rain cover. Simultaneously, by improving the durability and maintenance efficiency of the rain cover, long-term cost-effectiveness is achieved. The introduction of the connecting component 6 not only improves the structural stability of the rain cover but also ensures the safe and stable operation of the fan in various environments by optimizing the ventilation path and reducing wind resistance, thereby improving the overall safety and reliability of the system.

[0078] Furthermore, multiple first rainproof components 201 are arranged relatively independently, and each first rainproof component 201 is fixedly connected to the connecting assembly 6; or,

[0079] Multiple first rainproof components 201 are integrally formed with connecting components 6.

[0080] Specifically, the relatively independent first rainproof component 201 is fixedly connected to the connecting assembly 6: The first rainproof component 201 adopts a relatively independent design, with each component having independent waterproofing and airflow guiding functions. It can be customized according to the size and shape of the fan 5 to achieve the best waterproofing effect. Each first rainproof component 201 is fixedly connected by the connecting assembly 6 (multiple support rods 601), using screws, clips, or other fasteners to achieve a secure installation, ensuring that the rainproof components will not loosen or deform under various weather conditions. This design allows each first rainproof component 201 to be installed and removed independently, simplifying the maintenance and inspection process. If a damaged component needs to be replaced, only the corresponding first rainproof component 201 needs to be removed, without disassembling the entire rainproof cover, reducing maintenance costs and time.

[0081] The first rainproof component 201 and the connecting assembly 6 are integrally molded: The first rainproof component 201 and the connecting assembly 6 are manufactured using an integral molding method, combining the rainproof component and the supporting structure into one unit, forming a more robust and seamless waterproof barrier. The integral molding design typically employs processes such as injection molding and die casting, using polymer materials (such as polycarbonate PC) or metal materials (such as aluminum alloy) to achieve lightweight and high strength in the structure. Although the integral molding design may require more initial setup during installation, once installed, its connection stability and sealing performance are significantly improved. Furthermore, while maintenance of an integrally molded rain cover usually involves inspecting the entire structure, this design also reduces the likelihood of failure at the connection points between components, thereby reducing long-term maintenance requirements.

[0082] Whether installed independently or integrated with the connecting component 6, the design of the first rainproof component 201 significantly improves the waterproof performance of the rain cover, especially against splashing and direct sunlight. The combined use of the first rainproof component 201 and the connecting component 6 reduces return air resistance by minimizing structural connection points and optimizing the streamlined design, ensuring efficient ventilation and heat dissipation for the fan 5. The integrated design improves the overall structural stability of the rain cover, reduces relative movement and connection failures between components, and enhances system reliability. The independent installation enhances local structural stability and durability by distributing the load. The relatively independent first rainproof component 201 simplifies the maintenance and replacement process of the rain cover, reducing maintenance costs and time. While the integrated design may require more stringent component replacement, it achieves long-term economic benefits by reducing maintenance frequency. The independent first rainproof component 201 can more flexibly adapt to fans 5 of different sizes and shapes, improving the adaptability and versatility of the rain cover. The integrated design allows for customized production to meet the waterproof requirements of specific application scenarios. The one-piece molding design reduces assembly steps in the manufacturing process, lowering production costs and increasing the production efficiency of rain covers. The relatively independent design also offers advantages in terms of maintenance costs, ensuring the long-term benefits of the rain cover.

[0083] Furthermore, the supporting structure also includes:

[0084] The support component 7 has one end connected to at least one of the plurality of first rainproof components 201, and the other end of the support component 7 is used to connect to the support base.

[0085] The support assembly 7 is connected to the first rainproof component 201 located at the far end of the plurality of first rainproof components 201.

[0086] Specifically, the support component 7 is made of high-strength, corrosion-resistant materials, such as stainless steel, high-strength aluminum alloy, or special polymer materials. It is designed as a telescopic or adjustable rod-like structure to accommodate different height requirements. One end of the support component 7 is fixedly connected to the first rainproof component 201 at the far end via connectors (such as screws, bolts, clips, etc.). This connection method must ensure that the support component 7 can stably support the first rainproof structure 2 under severe weather conditions, preventing structural deformation or damage. The other end of the support component 7 is fixed to a support base, which can be the ground, a wall, or other stable structure to ensure the overall installation firmness and stability of the rainproof cover. In this embodiment, the support base is the lug 502 on the fan assembly 9; the specific relationship will be described in detail in subsequent embodiments. During installation, the position and angle of the support component 7 need to be precisely adjusted to ensure the most stable support structure is formed between it, the first rainproof component 201 at the far end, and the support base. The support component 7, together with multiple second rainproof components 301, forms a multi-layered protection system. By connecting to the first rainproof component 201 at the far end, the support assembly 7 not only strengthens the stability of the first rainproof structure 2 but also indirectly supports the second rainproof structure 3, improving the overall structural strength and waterproof performance of the rain cover. The introduction of the support assembly 7 significantly enhances the structural stability of the rain cover, especially under severe weather conditions such as strong winds and heavy rain. The connection to the first rainproof component 201 at the far end, and its fixation to the support foundation, forms a stable triangular support structure, ensuring the safety and reliability of the rain cover in various environments. The telescopic or adjustable length design of the support assembly 7 improves the adaptability and installation flexibility of the rain cover. Users can easily adjust the length of the support assembly 7 according to the specific environment and fan height, achieving more precise installation while reducing installation difficulty and time costs. The detachable connection between the support assembly 7 and the first rainproof component 201 simplifies the maintenance and replacement process of the rain cover. If any part of the rain cover is damaged or requires cleaning, it can be quickly disassembled and replaced without dismantling the entire support structure, reducing maintenance costs and time. By enhancing the stability of the rain cover, the support assembly 7 indirectly improves waterproofing performance, especially in supporting the second rainproof component 301. This ensures that rainwater will not penetrate the interior due to deformation of the rain cover structure, protecting the fan and electrical equipment from moisture damage. The robust support assembly 7 reduces vibration and displacement of the rain cover in severe weather, lowering potential risks to personnel and equipment below and improving the overall system safety. Although the introduction of the support assembly 7 may increase initial manufacturing costs, it achieves long-term cost benefits by improving the stability and durability of the rain cover and reducing the frequency of maintenance and replacement.The design of support component 7 takes into account the adaptability to different scenarios and fan sizes. Whether it is fixed or adjustable, it can ensure the effective installation and use of the rain cover under various conditions, thus improving the versatility and adaptability of the rain cover.

[0087] Furthermore, support component 7 includes:

[0088] Multiple support brackets 701 are arranged around a predetermined center line; multiple second fixing posts 203 are provided on the first rainproof structure 2, and the multiple second fixing posts 203 are arranged one-to-one with the multiple support brackets 701, so that the support brackets 701 are connected to the first rainproof structure 2 by second fastening components passing through each support bracket 701 and the corresponding second fixing post 203.

[0089] Specifically, multiple support brackets 701 are made of high-strength, corrosion-resistant materials, such as stainless steel, aluminum alloy, or high-strength plastic. Each support bracket 701 is arranged around a predetermined centerline, forming a ring-shaped support frame. This design can evenly distribute external forces, improving the stability and wind resistance of the structure. Multiple second fixing posts 203 are provided at corresponding positions on the first rainproof structure 2, their number and position matching the support brackets 701. The design of the second fixing posts 203 needs to consider the connection strength with the support brackets 701 and the ventilation resistance of the rainproof cover. The support brackets 701 and the second fixing posts 203 are connected by passing through second fastening components. The second fastening components can be screws, bolts, clips, or other fasteners, ensuring a secure connection and easy installation and disassembly. In some embodiments, the second fastening components can be designed with anti-loosening threads to enhance the stability of the connection. During installation, it is necessary to ensure that each support bracket 701 is aligned with its corresponding second fixing post 203, and connected by the second fastening components passing through both. The layout of the support bracket 701 and the position of the second fixed column 203 need to be adjusted according to the specific size of the fan and the design of the rain cover to ensure optimal support and ventilation performance. The other end of the support assembly 7 (i.e., the bottom of the support bracket 701) is used to connect to the support foundation. In some embodiments, the support foundation can be the ground, a wall, or other stable structure. The support bracket 701 can be embedded or directly fixed to the support foundation to form a stable lower support. Multiple support brackets 701 are arranged around a predetermined centerline to form a ring support structure, significantly enhancing the structural stability of the rain cover, especially in the face of severe weather conditions such as strong winds and heavy rain. This design reduces vibration and deformation of the rain cover structure by dispersing forces through evenly distributed support points. The connection method of the second fixed column 203 and the second fastening component simplifies the installation and disassembly process of the rain cover. If maintenance or replacement of the rain cover components is required, only the corresponding second fastening component needs to be removed, without completely disassembling the rain cover, reducing maintenance costs and time. In this embodiment, the second fastening component is a second fastening bolt. The design of the support bracket 701 takes into account the ventilation requirements of the rain cover, ensuring unobstructed ventilation paths. At the same time, the precise layout of the second fixing column 203 and the second fastening component reduces interference with airflow, further reduces wind resistance, and improves the ventilation efficiency of the rain cover.

[0090] Furthermore, the support bracket 701 includes two fixed plates 7011 arranged opposite to each other and a connecting plate 7012 connecting the two fixed plates 7011. One fixed plate 7011 is connected to a corresponding second fixed post 203 through a second fastening component, and the other fixed plate 7011 is connected to the support base through a third fastening component.

[0091] Furthermore, in each second rainproof component 301, both the first edge and the second edge are circular, and the diameter of the first edge is smaller than the diameter of the second edge.

[0092] Among the two adjacent first rainproof components 201 along the first direction, the diameter of the second edge of the first first rainproof component 201 is greater than the diameter of the first edge of the second first rainproof component 201.

[0093] Specifically, the support bracket 701 consists of two opposing fixed plates 7011 and a connecting plate 7012. The fixed plates 7011 are used to connect to the first rainproof structure 2 of the rain cover and the supporting foundation, while the connecting plate 7012 is used to stabilize the connection between the two fixed plates 7011, improving the rigidity and stability of the supporting structure. The structural design of the fixed plates 7011 and the connecting plate 7012 must ensure that they can withstand predetermined loads and wind forces during installation. Simultaneously, the thickness and width of the connecting plate 7012 should be reasonably selected based on the size and material strength of the rain cover. One fixed plate 7011 is connected to the second fixed post 203 on the first rainproof structure 2 via a second fastening component, typically using high-strength screws or clips, ensuring a secure connection and facilitating disassembly and maintenance. The other fixed plate 7011 is connected to the supporting foundation via a third fastening component, which can be a pre-embedded bolt, expansion screw, or chemical anchor, ensuring the connection strength and stability between the support bracket 701 and the supporting foundation. In this embodiment, the third fastening component is a third fastening bolt. In each second rainproof component 301, both the first and second edges are designed to be circular, with the diameter of the first edge being smaller than that of the second edge. This design facilitates the natural flow of rainwater along the surface of the second rainproof component 301, preventing rainwater from entering the fan. Simultaneously, the larger diameter of the second edge provides a wider ventilation path, reducing wind resistance and improving ventilation efficiency. For two adjacent first rainproof components 201 along the first direction, the diameter of the second edge of the first first rainproof component 201 is larger than the diameter of the first edge of the second first rainproof component 201. This design ensures that the previous first rainproof component can provide shelter and airflow for the next first rainproof component, forming a tiered protection structure, improving the overall waterproof performance of the rainproof cover while ensuring good ventilation performance. The support bracket 701, composed of a fixing plate 7011 and a connecting plate 7012, significantly enhances the support strength and stability of the rainproof cover. The use of the connecting plate 7012 improves the overall rigidity of the support structure, reduces vibration and displacement under severe weather conditions, and enhances the safety of the system. The connection between the support bracket 701, the second fixed column 203, and the support foundation via second and third fastening components simplifies the installation process of the rain cover and improves installation efficiency. Simultaneously, this design makes maintenance and replacement of rain cover components more convenient, reducing maintenance costs and time. The edge design of the second rain cover component 301 and the first rain cover component 201 not only improves the waterproof performance of the rain cover but also optimizes the ventilation path and reduces wind resistance, ensuring efficient operation of the fan in various environments and improving the system's ventilation efficiency and overall performance. The optimized design of the support bracket 701 and the rain cover components increases the adaptability and versatility of the rain cover, making it suitable for fans of different sizes and shapes, as well as various installation environments, thus enhancing the rain cover's market competitiveness.

[0094] Furthermore, the difference between the diameter d1 of the second edge of the first rainproof component 201 at the very end and the diameter d2 of the housing to be rainproofed is 50mm, wherein the housing to be rainproofed is the outer shell of the fan 5.

[0095] Specifically, during installation, it is necessary to ensure that the diameter d1 of the second edge of the first rainproof component 201 at the very end and the diameter d2 of the housing to be rainproofed are precisely aligned and fixed according to the set diameter difference (50mm). This precise fit not only enhances the rainproof effect but also ensures smooth airflow, reduces wind resistance, and improves ventilation efficiency. The support assembly 7 works in conjunction with the optimized design of the first rainproof component 201 to ensure the structural stability and installation reliability of the rainproof cover. The layout and installation position of the support bracket 701 need to be adjusted according to the specific dimensions of the first rainproof component 201 to form a stable support system. Different cabinet air conditioners and fans may require first rainproof components 201 with different diameter differences. To meet this need, the design considers the customization and serialized production of components, ensuring that the rainproof cover can adapt to various fan sizes and improving versatility. The design, which sets a 50mm diameter difference between the diameter d1 of the second edge of the first rainproof component 201 at the very end and the diameter d2 of the shell to be protected from rain, effectively prevents rainwater from seeping through the gaps between the components, improving the waterproof performance of the rainproof cover and ensuring the electrical safety and operational stability of the internal equipment. This design ensures smooth airflow between the first rainproof components 201, reduces wind resistance, improves ventilation efficiency, and guarantees the efficient operation of the fan under various environmental conditions. Combined with the optimized support assembly 7, the overall structural stability and installation reliability of the rainproof cover are ensured. Under severe weather conditions such as strong winds and heavy rain, the rainproof cover remains stable, preventing structural deformation or component loosening. The design of the first rainproof component 201 with a fixed diameter difference simplifies the alignment and adjustment steps during installation. Simultaneously, the optimized quick connection method between the support assembly 7 and the first rainproof component 201 facilitates maintenance and component replacement, reducing maintenance costs and time. The customized and serialized design approach allows the rainproof cover to adapt to fans of different sizes and layouts, improving its adaptability and market versatility.

[0096] Furthermore, the outer peripheral surfaces of multiple first rainproof components 201 together form a conical rain-guiding surface.

[0097] Specifically, if Figure 5 and Figure 6As shown, a represents the direction of rainwater flow, b represents the direction of splashing rainwater flow, and c represents the direction of wind flow. The outer circumference of multiple first rainproof components 201 adopts a conical design, collectively forming a unified rain-guiding surface. This design allows rainwater to flow naturally along the conical surface, reducing rainwater retention on the rain cover and further improving the waterproof effect. The angle and curvature of the conical surface need to be precisely designed according to the position and size of the fan 5 to ensure that rainwater is smoothly guided to the preset drainage path.

[0098] This application also provides a fan device, including a fan assembly 9, on which a support foundation is provided. The fan device also includes a rain cover as described above, which is provided on the support foundation.

[0099] The fan assembly 9 includes a fan 5 and a fan housing 501 disposed on the outside of the fan 5. The supporting base consists of a plurality of lugs 502 disposed on the fan housing 501 and protruding toward the outside of the fan housing 501.

[0100] The rain cover is mounted on the support base of the fan assembly 9. The support base consists of multiple lugs 502 on the fan housing 501, which protrude outwards from the fan housing 501. The lugs 502 not only serve as the mounting base for the rain cover but also enhance the structural stability of the fan housing 501. The rain cover is securely connected to the lugs 502 via the support assembly 7, ensuring the rain cover's secure and reliable installation under various weather conditions. The first rainproof component 201 is installed above the second rainproof component 301, forming a certain gap between itself and the support base (lugs 502) to ensure good ventilation. The conical rain-guiding surface design significantly improves the rain cover's waterproof performance, allowing rainwater to flow smoothly down the surface of the rain cover, preventing it from entering the fan 5 and protecting the fan and electrical equipment from moisture damage. The conical design optimizes the airflow path, reducing airflow stagnation and rebound on the rain cover, lowering return air resistance, ensuring efficient ventilation and heat dissipation of the fan 5, and improving the overall operating efficiency of the fan unit. The secure connection with the lugs 502 on the fan housing 501 enhances the overall structural stability and installation reliability of the rain cover. The lugs 502 increase the structural strength of the fan housing 501, improving the wind resistance and service life of the entire fan unit. The quick-connection method between the rain cover and the lugs 502, and its use in conjunction with the support assembly 7, simplifies the installation and disassembly process of the rain cover, facilitating regular inspection and maintenance, and reducing maintenance costs and time. The robust connection and optimized airflow path reduce vibration and displacement of the rain cover in severe weather, lowering potential risks to personnel and equipment below, and improving the safety of the entire fan unit.

[0101] This application also provides a cabinet air conditioner, which includes a fan device as described above, and the fan device is mounted on the cabinet 10.

[0102] Specifically, this application also provides a cabinet air conditioner, including the above-mentioned fan device, wherein the fan device is mounted on the cabinet 10.

[0103] Specifically, the cabinet 10 of the rack air conditioner has reserved installation space on its top or side for installing the aforementioned fan unit. This fan unit includes a fan assembly 9, a support base, and a rain cover. The fan assembly 9 consists of a fan 5 and a fan housing 501. The support base consists of multiple lugs 502 on the fan housing 501 for fixing the rain cover. The rain cover is securely connected to the support base (lugs 502) via the support assembly 7. The support assembly 7 includes multiple support brackets 701, each consisting of two fixing plates 7011 and a connecting plate 7012. One fixing plate is connected to the second fixing post 203 via a second fastening component, and the other fixing plate is connected to the lugs 502 via a third fastening component. The outer circumferential surfaces of the second rainproof component 301 together form a conical rain-guiding surface. The multiple first rainproof components 201 of the first rainproof structure 2 are designed to cooperate with the second rainproof component 301 to form a double waterproof structure. In the design of the cabinet 10 of the rack air conditioner, the ventilation balance between the rain cover and the cabinet 10 needs to be considered. This ensures that the air intake and exhaust of the fan 5 can flow freely, avoiding excessive resistance to airflow from the rain cover. Simultaneously, by optimizing the airflow guide design of the rain cover, it ensures that rainwater can flow smoothly down and not enter the rack interior. The introduction of the rain cover significantly improves the waterproof rating of the rack air conditioner, especially in the external circulation fan section, effectively preventing rainwater from directly splashing onto the fan 5 and fan casing 501, further improving the electrical safety and operational reliability of the rack air conditioner, and reducing the equipment failure rate caused by rainwater intrusion.
