Description

Technical Field

[0001] The utility model relates to the technical field of generator heat dissipation equipment, in particular to a generator ventilation and heat dissipation system. Background Art

[0002] Air cooling systems in the wind power industry are a critical heat dissipation solution, designed to keep the temperature of equipment within wind turbines within safe limits. These generators generate significant heat during operation, and electronic equipment such as generators and converters are particularly susceptible to overheating, which can affect equipment performance and lifespan. Air cooling systems dissipate heat through natural or forced air flow and typically include components such as fans, air intakes, and exhaust vents. Cool air flows through the equipment, removing internal heat and exhausting it, creating a continuous temperature-controlled cycle. Well-designed air cooling can improve generator efficiency and reduce failures caused by high temperatures, thereby extending the equipment's lifespan.

[0003] Generator ventilation and heat dissipation are closely related to the air cooling system, which works together to ensure the normal operation of the equipment. Generators generate heat during power generation. If heat cannot be dissipated in a timely manner, it can lead to overheating and even pose a safety hazard. Therefore, the ventilation and heat dissipation function of the generator depends on the effectiveness of the air cooling system, ensuring smooth air circulation and removing excess heat.

[0004] However, existing generator ventilation and cooling systems utilize an integrated, planar filter system, which creates resistance as air flows through the filter, making it difficult to maintain adequate ventilation area and thus affecting air flow efficiency. This increased resistance weakens the heat dissipation effect, making it difficult to maintain the internal temperature of the generator within the ideal operating range, thereby increasing the risk of overheating. Overheating not only affects the generator's power generation efficiency but also accelerates the aging of the insulation material, thereby shortening the equipment's service life. Therefore, a generator ventilation and cooling system is proposed to address these technical issues. Utility Model Content

[0006] This application provides a generator ventilation and heat dissipation system, which adopts the following technical solutions:

[0007] A generator ventilation and heat dissipation system comprises a supporting base plate, wherein a first side plate and a second side plate are provided on the upper surface of the supporting base plate, the tops of the first side plate and the second side plate are connected by a top plate, one side of the first side plate and one side of the second side plate are fixedly connected by a curved back plate, a semi-enclosed cavity is formed between the first side plate, the second side plate, the top plate, the curved back plate and the supporting base plate, and an air outlet is formed on the other side of the first side plate and the second side plate, an air inlet is provided inside the supporting base plate, a drive motor is provided on the top plate, an output end of the drive motor passes through the top plate and is connected to a turbofan, and the turbofan rotates in the semi-enclosed cavity;

[0010] By adopting the above technical solution, the turbofan is driven by the driving motor to rotate. By utilizing the rotation of the turbofan, the turbofan stirs the interior of the semi-enclosed cavity to form an airflow. The airflow enters the interior of the semi-enclosed cavity through the air inlet and passes through the air outlet to form an airflow path. A support frame with an inverted V-shaped structure is provided on the airflow path. The inverted V design is used to increase the airflow intake area, ensure that the wind speed of the airflow through the filter is 2.5M / s, ensure that the initial resistance of the filter is not greater than 50Pa, ensure the ventilation area, and thus ensure the required ventilation and heat dissipation air volume.

[0012] By adopting the above technical solution, after the mounting plate is placed into the mounting hole and effectively positioned, the mounting plate can be firmly fixed to the top plate by tightening the screws. This design significantly simplifies the installation and disassembly process and improves efficiency. Workers can easily complete the positioning and fixation of the mounting plate, thereby realizing the rapid disassembly and assembly of the drive motor, reducing the difficulty and time required for installation.

[0013] Preferably, a handle is provided on the mounting plate, and the handle is fixedly connected to the mounting plate.

[0014] By adopting the above technical solution, the handle serves as an auxiliary operating tool, aiming to improve the user's grip and operation convenience of the mounting plate during adjustment, installation or maintenance. This optimized grip design significantly improves the smoothness of installation and removal, ensuring that users can operate more efficiently and safely when handling related tasks.

[0015] Preferably, an air gathering sleeve is provided inside the air inlet of the supporting base plate, and the cross-sectional dimension of the middle portion of the air gathering sleeve is smaller than the cross-sectional dimensions at both ends thereof.

[0016] By adopting the above technical solution, the wind-collecting sleeve is designed to effectively gather the surrounding air and enhance the gas collection and guidance functions by accelerating the airflow; this feature makes it suitable for systems that require wind collection or ventilation, improving work efficiency and performance.

[0017] Preferably, the support frame includes a bottom frame, on which a first inclined frame and a second inclined frame are respectively provided. The tops of the first inclined frame and the second inclined frame are inclined inward, and a support structure with an inverted "V"-shaped longitudinal section is formed on the bottom frame.

[0018] By adopting the above technical solution, the inclined design of the first bevel frame and the second bevel frame is intended to effectively guide the airflow to converge towards the center, thereby promoting the airflow through the filter module; this inclined structure not only reduces the resistance of the airflow when passing through the filter, but also significantly improves the passage efficiency of the airflow.

[0019] Preferably, the first and second inclined frames are both provided with ribs inside, and the ribs separate the internal spaces of the first and second inclined frames into two filtering areas, and filtering modules are provided in the filtering areas of the first and second inclined frames.

[0020] By adopting the above technical solution, the arrangement of the ribs divides the internal space of the first bevel frame and the second bevel frame into two independent filtration areas; this design enables each filtration area to operate independently, thereby optimizing the air filtration effect and effectively avoiding cross-contamination between different areas.

[0021] Preferably, the filter module comprises an outer frame, and the outer frame is detachably arranged between the filter areas of the first bevel frame and the second bevel frame.

[0022] By adopting the above technical solution for quickly assembling and disassembling the filter module, the user can quickly replace and maintain the filter module, thereby improving the convenience of operation.

[0023] Preferably, a filter core layer is provided inside the outer frame, and the filter core layer is provided with at least two layers.

[0024] By adopting the above technical solution, the double-layer filter element design can achieve diverse filtering effects, thereby optimizing the air flow path, reducing airflow resistance, and increasing the speed and efficiency of air passing through the filter element; this structural design not only ensures improved filtering performance, but also enhances the operating effect of the overall system.

[0025] Preferably, the filter core layer is made of polyester fiber.

[0026] By adopting the above technical solution, it has good filtration efficiency and moisture resistance and is suitable for capturing larger particles.

[0027] Preferably, an interlayer is formed between two adjacent filter core layers, and an activated carbon layer is provided inside the interlayer.

[0028] By adopting the above technical solutions, activated carbon is a highly porous material with a large number of tiny pores inside; these pores enable it to effectively adsorb harmful substances in gases and liquids, thus playing an important role in purifying air and water quality.

[0029] In summary, this application has the following beneficial effects:

[0030] 1. The turbofan rotates by driving the motor. With the rotation of the turbofan, the turbofan stirs the interior of the semi-enclosed cavity to form an airflow. The airflow enters the interior of the semi-enclosed cavity through the air inlet and passes through the air outlet to form an airflow path. A support frame with an inverted V-shaped structure is provided on the airflow path. The inverted V design increases the airflow intake area, ensures that the airflow speed through the filter is 2.5M / s, ensures that the initial resistance of the filter is not greater than 50Pa, ensures the ventilation area, and thus ensures the required ventilation and heat dissipation air volume.

[0031] 2. The system adopts a modular design, which facilitates subsequent maintenance and repair by separating the cooling fan and the filtration system. At the same time, it simplifies the structure of the entire system, saves materials, and changes the strength requirements of the entire system required by the original integrated design. The cooling fan part ensures structural strength, while the filtration system only installs filters and has no vibration source, so the required structural strength is relatively reduced, making this part lightweight, saving materials, and meeting the requirements of green ecological design.

DETAILED DESCRIPTION

[0040] The present application is described in further detail below in conjunction with the accompanying drawings. It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content. Example

[0041] The utility model discloses a generator ventilation and heat dissipation system, such as Figure 1 and Figure 2 As shown, it includes a supporting base plate 1, on the upper surface of the supporting base plate 1 and near the center position, a first side plate 2 and a second side plate 3 are fixedly installed, the tops of the first side plate 2 and the second side plate 3 are fixedly connected by a top plate 4, the rear sides of the first side plate 2 and the second side plate 3 are fixedly connected by an arc-shaped back plate 5, a semi-enclosed cavity is formed between the first side plate 2, the second side plate 3, the top plate 4, the arc-shaped back plate 5 and the supporting base plate 1, and an air outlet 7 is formed on the front side of the first side plate 2 and the second side plate 3, a circular air inlet 8 is provided inside the supporting base plate 1, and the air inlet 8 is located at the center position of the semi-enclosed cavity, a driving motor 9 is fixedly installed on the top plate 4, the output end of the driving motor 9 passes through the top plate 4 and is connected to a turbofan 6, and the turbofan 6 rotates in the semi-enclosed cavity.

[0042] like Figure 1 and Figure 2 As shown, the turbofan 6 rotates by driving the drive motor 9. With the rotation of the turbofan 6, the turbofan 6 stirs the interior of the semi-enclosed cavity to form an airflow. The airflow enters the interior of the semi-enclosed cavity through the air inlet 8 and passes through the air outlet 7 to form an airflow path.

[0043] like Figure 1 and Figure 2 As shown, the drive motor 9 installed on the top plate 4 provides power, and the output shaft passes through the top plate 4 to connect to the turbofan 6; the output end of the drive motor 9 drives the turbofan 6 to rotate, and the blades of the turbofan 6 cut the air by rotation to generate airflow; when the turbofan 6 rotates, it stirs the air in the semi-enclosed cavity to form a local low-pressure area, so that the external air flows into the semi-enclosed cavity through the air inlet 8; after the air enters the cavity through the air inlet 8, it is pushed to the air outlet 7 by the airflow generated by the stirring of the turbofan 6 to be discharged, thereby taking away the heat generated when the generator is working; by means of forced airflow, the heat generated inside the generator can be more effectively taken away to prevent overheating; the semi-enclosed design of the system enables the airflow to be evenly distributed to various parts, avoiding heat concentration in a certain part, thereby improving the working stability of the generator.

[0044] like Figure 2 As shown, specifically, a mounting hole 10 is provided at the inner center position of the top plate 4, and the mounting hole 10 is coaxially arranged with the air inlet 8. A mounting plate 11 is fixedly installed inside the mounting hole 10, and the mounting plate 11 is fixedly installed with the drive motor 9. An enlarged portion is provided on the top of the mounting plate 11, and the size of the enlarged portion of the mounting plate 11 is larger than the cross-sectional size of the mounting hole 10. In this way, it can be ensured that the mounting plate 11 will not pass directly through the mounting hole 10 during installation, forming a supporting surface, increasing the contact area, and reducing stress concentration; a plurality of screws 12 are provided on the enlarged portion of the mounting plate 11, and the screws 12 is set at equal angles around the central axis of the mounting plate 11. When the mounting plate 11 is placed in the mounting hole 10 and positioned, the screw 12 can be tightened to firmly fix the mounting plate 11 on the top plate 4; this multi-point fixing method can effectively disperse the force and enhance stability; when the mounting plate 11 is positioned and installed inside the mounting hole 10, the mounting plate 11 is fixed to the top plate 4 by the screw 12; this design makes the installation and disassembly process simple and efficient, and workers can easily position and fix the mounting plate 11, which is convenient for quick disassembly and assembly of the drive motor 9, reducing the difficulty and time of installation.

[0045] like Figure 2As shown, two handles 13 are fixedly installed on the mounting plate 11, and the handles 13 are fixedly connected to the mounting plate 11. The handles 13 serve as an auxiliary operating tool, allowing the user to grasp and operate the mounting plate 11 more conveniently when adjustment, installation or maintenance is required; this enhanced gripping design makes the installation and disassembly process smoother; the handles 13 are set at the edge of the mounting plate 11, so that the user can effectively disperse the pressure when lifting or applying force, reduce local stress concentration, and thus maintain the integrity of the mounting plate 11; during the installation or maintenance process, the handles 13 provide a reliable gripping point, reducing the risk of accidental injury due to slippage or instability; users can be more confident when operating.

[0046] like Figure 1 and Figure 2 As shown, specifically, an air gathering sleeve 14 is fixedly installed inside the air inlet 8 of the supporting base plate 1, and the middle cross-sectional dimension of the air gathering sleeve 14 is smaller than the cross-sectional dimension at its own two ends; this means that when the air flow enters the sleeve, the flow velocity of the fluid (air) will increase when it flows through the narrow part in the middle of the sleeve; this is because when the fluid passes through a narrowing channel, its speed must be increased to maintain the continuity of the flow; according to Bernoulli's principle, when the flow velocity increases, the static pressure of the fluid will decrease; this change in pressure can guide more airflow into the sleeve, thereby improving the airflow guidance effect; by accelerating the airflow, the air gathering sleeve 14 can achieve larger mass airflow guidance and aggregation at lower energy consumption, thereby improving the overall ventilation efficiency of the system.

[0047] like Figure 3 and Figure 4 As shown, two filter systems 15 are symmetrically arranged on the upper surface of the supporting base plate 1 and about the central axis of the top plate 4. The filter systems 15 are used to remove impurities in the air, and the filter systems 15 are located on the airflow path.

[0048] like Figure 3 and Figure 4 As shown, when air flows through the filter system 15, the air flow speed will decrease, and impurities will be intercepted and adsorbed by the filter medium due to inertia, collision or electrostatic adsorption. The design position of the filter system 15 ensures that every incoming air must be filtered to effectively remove pollutants. By removing impurities in the air, the filter system 15 can significantly improve the quality of the air entering the generator and protect the equipment from dust and particulate matter.

[0049] like Figure 4 and Figure 5As shown, the filtration system 15 includes a support frame 1501 and a filtration module 1502 installed on the support frame 1501. Specifically, the support frame 1501 includes a bottom frame 150101 with a rectangular cross-section, and a first bevel frame 150102 and a second bevel frame 150103 are fixedly installed on two opposite long sides of the bottom frame 150101. The bottoms of the first bevel frame 150102 and the second bevel frame 150103 are fixedly connected to the two long sides of the bottom frame 150101, respectively. The tops of the first bevel frame 150102 and the second bevel frame 150103 are inclined inward, and a support structure with an inverted "V"-shaped structure in longitudinal section is formed on the bottom frame 150101.

[0050] like Figure 4 and Figure 5 As shown, the inverted V design is used to increase the air intake area, ensure that the air flow through the filter is at a speed of 2.5M / s, ensure that the initial resistance of the filter is not greater than 50Pa, and thus ensure the required ventilation and heat dissipation air volume; and the inverted "V" shape structure lowers the center of gravity of the system, thereby enhancing the stability of the structure; at the same time, this structure can effectively guide the air flow, so that the air has a better distribution when passing through the filter module 1502; the middle of the first bevel frame 150102 and the second bevel frame 150103 are fixedly installed with a rib 150104, which connects the first bevel frame 150102 and the second bevel frame 150103. 102 and the internal space of the second bevel frame 150103 are separated into two independent filtering areas 150105. The filtering modules 1502 are fixedly installed in the filtering areas 150105 of the first bevel frame 150102 and the second bevel frame 150103. The setting of the ribs 150104 divides the internal space of the first bevel frame 150102 and the second bevel frame 150103 into two independent filtering areas 150105. This design allows each filtering area 150105 to work independently, which can better filter the air and avoid cross-contamination between different areas.

[0051] In general, through the optimized air flow path and independent filter area 150105 design, the system can increase the speed and efficiency of air passing through the filter module 1502, thereby improving the filtering effect.

[0052] like Figure 5 and Figure 6As shown, specifically, the filter module 1502 includes an outer frame 150201, and the outer frame 150201 is snap-connected with the filter area 150105 of the first bevel frame 150102 and the second bevel frame 150103. By snapping, the filter module 1502 can be firmly installed in the support structure to prevent the module from being displaced or falling off when the airflow passes through; this stable connection ensures the safety and effectiveness of the system during operation; the snap-connection design enables the filter module 1502 to be easily installed or disassembled, and the user can quickly replace and maintain the filter module 1502, thereby improving the convenience of operation; the diversified snap-connection design allows filter modules 1502 of different types and specifications to adapt to the same support structure, thereby meeting various air quality treatment requirements; this flexibility enables the system to be upgraded and modified according to actual needs; the snap-connection design eliminates the need for complicated tools and procedures when replacing the filter module 1502, thereby simplifying the maintenance process and reducing operating costs and time.

[0053] like Figure 7 As shown, the interior of the outer frame 150201 is provided with a filter element layer 150202, which is composed of two layers, an inner layer and an outer layer. The filter element layer 150202 is made of polyester fiber, which has good filtration efficiency and moisture resistance and is suitable for capturing larger particles. The combination of the inner and outer layers can achieve different filtration effects. The outer layer is mainly used to capture larger particles, while the inner layer is used to filter smaller particles and microparticles, providing a more comprehensive filtration effect. The pore size of the outer layer is larger than that of the inner layer, which helps to form a gradient filtration, so that large particles are captured first by the outer layer, while fine particles can be smoothly filtered by the inner layer. This design improves overall filtration efficiency. The double-layer structure can optimize the air flow path, reduce airflow resistance, and increase the speed and efficiency of air passing through the filter element. The outer layer blocks larger particles, which can reduce clogging of the inner layer, thereby extending the service life of the filter element. The multi-layer design can improve overall filtration efficiency and ensure that more particles and pollutants are effectively removed.

[0054] like Figure 7As shown, a sandwich is formed between the two filter element layers 150202, and an activated carbon layer 150203 is provided inside the sandwich. Activated carbon is a porous material with a large number of tiny pores, which can effectively adsorb harmful substances in gases and liquids, such as volatile organic compounds (VOCs), odors, chemical pollutants and certain gases (such as ammonia and benzene). The microporous structure of the activated carbon layer 150203 provides a large specific surface area, which increases the chance of contact with pollutants in the air, thereby improving the adsorption efficiency; the activated carbon layer 150203 works in conjunction with the outer and inner filter elements, first capturing large particles through the outer layer, and then the activated carbon layer 150203 further removes harmful gases and odors, and finally the inner layer captures tiny particles, forming a multi-stage filtration system 15, which improves the overall filtration effect; the activated carbon can effectively remove odors and harmful gases, and improve the freshness and safety of the air.

[0055] Working principle: The user or operator first turns on the external power supply of the driving motor 9, and the turbofan 6 rotates by driving the driving motor 9. With the rotation of the turbofan 6, the turbofan 6 stirs the interior of the semi-enclosed cavity to form an airflow, and the airflow enters the interior of the semi-enclosed cavity through the air inlet 8, and passes through the air outlet 7 to form an airflow path, and a support frame 1501 with an inverted V-shaped structure is provided on the airflow path. The inverted V design is used to increase the air intake area of ​​the airflow, ensure the ventilation area, and thus ensure the required ventilation and heat dissipation air volume.

[0056] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
