Detailed Implementation

[0024] The technical solutions of the present utility model will be explained and described below with reference to the accompanying drawings.

Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of the present utility model.

[0025] The following describes in detail, with reference to the accompanying drawings, a heat dissipation structure for a fiber optic switching box with air-cooled airflow according to an embodiment of the present invention.

[0026] Example

[0027] For ease of understanding, please refer to Figures 1 to 5. An embodiment of the heat dissipation structure of the fiber optic switching box with air cooling flow is provided by the present invention, including a heat dissipation air cooling flow assembly and a heat dissipation fan 3 installed at one end of the fiber optic switching box body 1. Several fixing components are provided on the upper edge of the fiber optic switching box body 1.

[0028] The heat dissipation and air cooling guide assembly includes several heat sinks 21 and several air cooling plates 22. The end face of the heat sink 21 is U-shaped, and several heat sinks 21 are fixedly connected to one end of the fiber optic switching box body 1. Several air cooling plates 22 are symmetrically distributed between the output end of the cooling fan 3 and several heat sinks 21.

[0029] It should be noted that the heat dissipation and air cooling guide assembly consists of several heat sinks 21 and air cooling guide plates 22. The heat sinks 21 have a U-shaped end face and are fixed to one end of the fiber optic switching box body 1 by welding or screws. The air cooling guide plates 22 are symmetrically distributed between the output end of the cooling fan 3 and the heat sinks 21, and are made of a metal material with high thermal conductivity, such as aluminum alloy, with a smooth surface to reduce airflow resistance. The U-shaped heat sinks 21 significantly improve heat conduction efficiency by increasing the surface area of ​​the heat sinks 21, accelerating the transfer of heat from the inside of the fiber optic switching box to the external environment. The symmetrically distributed air cooling guide plates 22 optimize the airflow path, so that the air blown by the cooling fan 3 is evenly distributed on the surface of the heat sinks 21, reducing airflow turbulence and improving air cooling efficiency. Integrating the heat sinks 21 and the air cooling guide plates 22 at one end of the fiber optic switching box body 1 saves space and facilitates installation and maintenance.

[0030] In some embodiments, the fixing assembly comprises a movable part 5, a snap-fit ​​assembly, a connecting post 8, and a suction cup 6. The movable part 5 is slidably connected inside the fiber optic switching box body 1. The snap-fit ​​assembly is fixed inside the fiber optic switching box body 1. The connecting post 8 is fixedly installed at the lower part of the movable part 5. The suction cup 6 is fixed to the bottom of the connecting post 8. The fiber optic switching box body 1 has an installation cavity 12 inside. The connecting post 8 has a vent hole 9 communicating with the suction cup 6 and a connecting groove 10. A sealing ring 13 adapted to the connecting groove 10 is fixedly installed in the installation cavity 12. The vent hole 9 communicates with the installation cavity 12 through the connecting groove 10. An exhaust port 11 penetrating the fiber optic switching box body 1 is provided inside the installation cavity 12.

[0031] The fixing assembly consists of a movable part 5, a snap-fit ​​assembly, a connecting post 8, and a suction cup 6. The movable part 5 is slidably connected to the inside of the fiber optic switching box body 1 via a slide rail. The snap-fit ​​assembly, which includes a spring and a locking element 15, is fixed inside the fiber optic switching box body 1. The connecting post 8 is fixedly installed at the lower part of the movable part 5, and a suction cup 6 is fixed at its bottom. The connecting post 8 has a vent hole 9 and a connecting groove 10 inside, and the vent hole 9 communicates with the mounting cavity 12 through the connecting groove 10. A sealing ring 13 is fixed inside the mounting cavity 12 to ensure airtightness. The suction cup 6 forms a negative pressure adsorption with the mounting surface, enhancing the stability of the fixing assembly and preventing the equipment from falling off due to vibration or external force. The sealing ring 13 prevents external dust from entering the inside of the fiber optic switching box, protecting the internal electronic components from contamination. The cooperation between the locking element 15 and the locking groove 16, combined with the elastic force of the spring, enables the movable part 5 to be quickly locked and released, facilitating the installation and disassembly of the equipment.

[0032] An exhaust port 11 is provided inside the mounting cavity 12, penetrating the fiber optic switching box body 1. The exhaust port 11 is located on the top or side wall of the fiber optic switching box body 1, and its size matches that of the vent hole 9 and the connecting groove 10 to ensure smooth airflow. The exhaust port 11 and the vent hole 9 form an airflow channel, accelerating the discharge of internal hot air and preventing heat accumulation inside the switching box. Through the reasonable layout of the exhaust port 11, the internal temperature of the fiber optic switching box is reduced, extending the service life of the equipment.

[0033] In some embodiments, the snap-fit ​​assembly includes a spring and a snap-fit ​​15. The movable part 5 has a movable chamber 14 inside, the spring is fixedly installed inside the movable chamber 14, one end of the movable part 5 is fixedly installed on the spring, and the fiber optic switching box body 1 is provided with a snap-fit ​​slot 16 that matches the snap-fit ​​15.

[0034] It should be noted that the snap-fit ​​assembly includes a spring and a snap-fit ​​15. The movable part 5 has a movable chamber 14 inside, the spring is fixedly installed inside the movable chamber 14, one end of the snap-fit ​​15 is connected to the spring, and the other end matches the snap-fit ​​slot 16 inside the fiber optic switching box body 1.

[0035] The elastic force of the spring absorbs the impact force during installation, protecting the clip 15 and the slot 16 from damage. The clip 15 can be finely adjusted in position as the movable part 5 moves to adapt to the differences in flatness of different mounting surfaces, ensuring a secure fixation effect.

[0036] In some embodiments, a magnetic suction element 7 is fixedly installed at the bottom of the fiber optic switching box body 1.

[0037] It should be noted that a magnetic chuck 7 is fixedly installed at the bottom of the fiber optic switching box body 1. The magnetic chuck 7 is made of a high-magnetic permanent magnet material, such as neodymium iron boron, and is fixed to the bottom of the fiber optic switching box body 1 by screws or adhesives, forming a magnetic attraction with the metal mounting surface, such as an iron bracket.

[0038] The magnetic connector 7 enables rapid installation of the fiber optic switching box without the need for complex tools, making it especially suitable for scenarios requiring frequent repositioning. The magnetic connector 7's adhesion to the mounting surface provides additional fixing force, preventing the equipment from shifting due to vibration or external forces.

[0039] In some embodiments, the cooling fan 3 includes a frame, fan blades, and a drive motor. The fan blades are fixedly connected to the output shaft of the drive motor, and the drive motor is fixedly mounted on the frame.

[0040] It should be noted that the cooling fan 3 includes a frame, fan blades, and a drive motor. The fan blades are fixedly connected to the output shaft of the drive motor with screws.

The fan blades are made of lightweight, high thermal conductivity materials, such as plastic or aluminum alloy, and the drive motor is a low-noise DC motor.

[0041] In some embodiments, the surface of the air-cooled guide plate 22 is provided with a plurality of through holes 23.

[0042] It should be noted that the surface of the airflow cooling plate 22 has several through holes 23. These through holes 23 are arranged in an array, with their diameter matching the spacing of the heat sink 21. The hole diameter ranges from 1 to 3 mm, and the material is the same as that of the airflow cooling plate 22. The through holes 23 increase the contact area between the airflow and the airflow cooling plate 22, accelerating the transfer of heat from the airflow cooling plate 22 to the external environment. The array distribution of the through holes 23 reduces airflow resistance, improving the cooling efficiency of the heat sink 3.
