Description

Technical Field

[0001] This utility model relates to a fan drive structure and belongs to the field of fan drive technology. Background Technology

[0002] As the "intermediate control unit" between the wind turbine and the power grid, the wind turbine drive must simultaneously meet the requirements of efficient heat dissipation, reliable sealing, and convenient disassembly and assembly.

[0003] Existing technologies generally suffer from problems such as unreasonable structural design, inconvenient installation and maintenance, poor heat dissipation, significant electromagnetic interference, and insufficient sealing performance. Particularly in permanent magnet synchronous motor drive systems, traditional fan drive structures often employ a single metal casing design with an unoptimized internal component layout, resulting in low heat dissipation efficiency and a susceptibility to overheating and damage. Furthermore, the lack of effective vibration isolation and electromagnetic shielding measures means that vibrations and electromagnetic interference generated during drive operation can affect the stability and lifespan of the fan system. In addition, existing drive structures require the disassembly of multiple components during installation and maintenance, leading to cumbersome operations and increased maintenance costs and time. Therefore, there is an urgent need for a new fan drive structure to address these issues. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a fan drive structure to solve the problems mentioned in the background technology. This utility model has excellent heat dissipation performance, stable structure, shock resistance and insulation, good sealing performance, strong versatility, and convenient assembly and maintenance.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a fan drive structure, including a drive aluminum shell, a drive plastic shell, conductive copper pillars, and a drive universal bare plate. The drive plastic shell contains a first silicone spacer, a second silicone spacer, a third silicone spacer, a fourth silicone spacer, and a fifth silicone spacer, installed inside by multiple terminal screws. The drive plastic shell is mounted on the upper end of the drive aluminum shell by multiple second screws, and a sealing O-ring is embedded at the connection between the drive plastic shell and the drive aluminum shell. The drive universal bare plate is fixed to the drive plastic shell and the drive aluminum shell by multiple combination screws. Multiple conductive copper pillars are installed on the upper end of the drive universal bare plate. A first thermally conductive film and a second thermally conductive film are adhered to the connection between the drive universal bare plate and the drive aluminum shell.

[0006] Furthermore, a driver plastic cover plate is installed on the upper end of the driver plastic housing by a plurality of first screws, and the driver plastic cover plate covers the upper ends of the first silicone partition, the second silicone partition, the third silicone partition, the fourth silicone partition, and the fifth silicone partition.

[0007] Furthermore, a driver light guide post is mounted on the upper end of the driver universal bare board, and the driver light guide post protrudes through the driver plastic shell.

[0008] Furthermore, the upper ends of the plurality of conductive copper pillars are respectively located within the first silicone spacer, the second silicone spacer, the third silicone spacer, the fourth silicone spacer, and the fifth silicone spacer, and the upper ends of the plurality of conductive copper pillars are respectively electrically connected to the plurality of terminal screws.

[0009] Furthermore, a control port terminal pin holder is mounted on the upper end of the universal bare board of the driver, and a terminal housing is mounted on the outside of the control port terminal pin holder, with the terminal housing embedded in one side of the upper end of the driver's plastic shell.

[0010] Furthermore, the aluminum housing side surface of the driver is provided with multiple heat dissipation fins.

[0011] The beneficial effects of this utility model are as follows: This utility model provides a fan drive structure. Through modular design, it rationally arranges components such as the drive plastic cover, drive plastic shell, drive universal bare board, conductive copper pillars, silicone spacers, thermal conductive film, drive light guide, sealing O-ring, control port terminal pin seat, and terminal shell. This achieves a compact and modular design of the drive, greatly improving its structural rationality and sealing performance. Furthermore, the placement of the first and second thermal conductive films effectively conducts the heat generated by the drive universal bare board to the drive aluminum shell, significantly improving heat dissipation efficiency and extending the drive's service life. The evenly distributed silicone spacers effectively absorb vibrations during drive operation, reducing the impact of vibrations on internal components and improving system stability and reliability. Simultaneously, the combination of silicone spacers and the drive plastic shell provides excellent electromagnetic shielding, effectively reducing electromagnetic interference and ensuring stable drive operation. Finally, all screws used are standardized screws, requiring only a Phillips screwdriver for assembly and disassembly, greatly reducing maintenance time, improving versatility, and enhancing practicality.

Detailed Implementation

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] Please see Figures 1-7 This utility model provides a technical solution: a fan driver structure, including a driver aluminum shell 19, a driver plastic shell 16, conductive copper pillars 7, and a driver universal bare plate 8. The driver plastic shell 16 has a first silicone spacer 3, a second silicone spacer 4, a third silicone spacer 5, a fourth silicone spacer 6, and a fifth silicone spacer 15 installed inside via multiple terminal screws 13. The driver plastic shell 16 is covered on the upper end of the driver aluminum shell 19 by multiple second screws 12, and a sealing O-ring 17 is embedded at the connection between the driver plastic shell 16 and the driver aluminum shell 19. The driver universal bare plate 8 is installed and fixed inside the driver plastic shell 16 and the driver aluminum shell 19 by multiple combination screws 10. Multiple conductive copper pillars 7 are installed on the upper end of the driver universal bare plate 8. A first thermally conductive film 9 and a second thermally conductive film 11 are attached to the connection between the driver universal bare plate 8 and the driver aluminum shell 19. This design solves the problems of unreasonable structural design, inconvenient installation and maintenance, poor heat dissipation, large electromagnetic interference, and insufficient sealing performance commonly found in existing fan driver technologies.

[0023] As the first embodiment of this utility model: A driver plastic cover plate 2 is installed on the upper end of the driver plastic housing 16 by a plurality of first screws 1, and the driver plastic cover plate 2 covers the upper ends of the first silicone spacer 3, the second silicone spacer 4, the third silicone spacer 5, the fourth silicone spacer 6, and the fifth silicone spacer 15. The driver plastic cover plate 2 is fixed to the upper end of the driver plastic housing 16 by a plurality of first screws 1, forming a complete top closed structure, which effectively prevents dust and foreign objects from entering the upper end of the driver plastic housing 16, and can also shield and protect the terminal screws 13 therein, while improving the overall appearance consistency.

[0024] The driver general bare board 8 has a driver light guide post 14 installed on the top, and the driver light guide post 14 protrudes through the driver plastic shell 16. The added driver light guide post 14 makes it easy for users to intuitively observe the driver's operating status and improves the human-computer interaction experience.

[0025] The upper ends of multiple conductive copper pillars 7 are respectively located inside the first silicone spacer 3, the second silicone spacer 4, the third silicone spacer 5, the fourth silicone spacer 6, and the fifth silicone spacer 15, and the upper ends of the multiple conductive copper pillars 7 are electrically connected to multiple terminal screws 13. By adding multiple conductive copper pillars 7, which are respectively set inside the first silicone spacer 3, the second silicone spacer 4, the third silicone spacer 5, the fourth silicone spacer 6, and the fifth silicone spacer 15, and electrically connected to the terminal screws 13, a reliable electrical connection between the circuit board and the external power supply and signal is realized. At the same time, the silicone spacers play a dual role of insulation and shock absorption.

[0026] The driver's universal bare board 8 has a control port terminal pin socket 18 mounted on its upper end. A terminal housing 20 is mounted on the outside of the control port terminal pin socket 18, and the terminal housing 20 is embedded in one side of the upper end of the driver's plastic housing 16. The added control port terminal pin socket 18 and the terminal housing 20 form a standardized external interface, which facilitates quick wiring and provides good insulation protection.

[0027] The side surface of the driver's aluminum housing 19 is provided with multiple heat dissipation fins. By adding heat dissipation fins, the heat dissipation area on the side of the driver's aluminum housing 19 can be increased, further improving the overall heat dissipation efficiency and ensuring stable operation of the driver in high-temperature environments.

[0028] As a second embodiment of this utility model: the heat generated by the universal bare board 8 of the driver during operation is efficiently conducted to the aluminum shell 19 of the driver through the first thermally conductive film 9 and the second thermally conductive film 11. The heat dissipation fins on the outer surface of the aluminum shell further enhance heat dissipation, forming a complete heat dissipation path and effectively controlling the temperature of the components; the first silicone spacer 3, the second silicone spacer 4, the third silicone spacer 5, the fourth silicone spacer 6 and the fifth silicone spacer 15 are evenly arranged around the universal bare board 8 of the driver and at key support points, which not only effectively absorb vibrations during operation, but also form an electromagnetic shielding layer through the combination of silicone material and plastic shell, reducing internal and external electromagnetic interference; the sealing O-ring 17 is placed between the plastic shell 16 of the driver and the aluminum shell 19 of the driver to form a reliable sealing interface, preventing moisture and dust from entering and adapting to complex industrial environments; all screws (first screw 1, second screw 12, two-combination screw 10, terminal screw 13) adopt a standardized design, and all disassembly and assembly operations can be completed using the same Phillips screwdriver, which greatly simplifies the production assembly and on-site maintenance process and improves the versatility and applicability of the product.
