Technical Field

[0001] The utility model relates to the technical field of switches, in particular to a heat dissipation mechanism for a switch. Background Art

[0002] During navigation, ships need to transmit and communicate extensive amounts of data, such as real-time ship position information and navigation records, with various devices, including shore offices, other ships, berths, and docks. As the backbone of network equipment, switches enable high-speed, stable data transmission and communication, ensuring the timeliness and reliability of information. Therefore, switches are essential network devices. During operation, switches draw in external air through fans, which removes heat through airflow and dissipates heat. However, ships sailing on the water are exposed to high levels of moisture in the surrounding air, which can enter the switch. This humid air can easily cause short circuits in internal electrical components, severely shortening the switch's lifespan. Utility Model Content

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figure 1-6As shown, a heat dissipation mechanism of a switch includes a body 1 and an air inlet 2 connected to one side of the body 1. The heat dissipation mechanism also includes an extrusion structure 11. The surface of the air inlet 2 is bolted with a first dustproof net 3. When external air enters the air inlet 2, most of the dust is intercepted by the first dustproof net 3. The interior of the air inlet 2 is also bolted with a first fan 4. A box body 7 is provided on the inner side of the air inlet 2. The box body 7 is slidably connected to the inner wall of the air inlet 2. A long column 8 is bolted to the side of the box body 7 away from the first fan 4. The air inlet 2 is located on the inner side of the body 1 and is connected to an air outlet cover 10. A vertical plate 9 is bolted to the upper part of the interior of the air outlet cover 10, and the long column 8 is rotatably connected to the vertical plate 9. , with the coordinated use of the long column 8 and the vertical plate 9, the box body 7 can rotate. A short column 5 is bolted to the side of the box body 7 close to the first fan 4. A connecting plate 6 is also bolted to the top of the inside of the air inlet tube 2, and the short column 5 is rotatably connected to the connecting plate 6 to provide a rotation point for the other side of the box body 7, thereby increasing the rotation stability of the box body 7. A sponge block 17 is provided inside the box body 7. The interior of the box body 7 is divided into three areas. Ventilation holes 16 are also penetrated on the back of the box body 7. The number of ventilation holes 16 is several and densely distributed in three areas. A vertical channel 12 is also penetrated at the bottom of the air inlet tube 2, and the bottom end of the vertical channel 12 penetrates to the outside of the body 1.

[0025] During use, the first fan 4 is turned on, which allows external air to pass through the first dustproof net 3 and enter the interior of the air inlet 2. When passing through the box body 7, the air can pass through the sponge block 17 and the ventilation hole 16, and most of the moisture in the air is absorbed by the sponge block 17, preventing humid air from entering the interior of the body 1, causing short circuit or even damage to the internal electrical components. In this way, the dehumidified air enters the interior of the body 1 through the air outlet hood 10 and absorbs the heat of the electrical components inside the body 1. The side of the body 1 away from the air inlet 2 is also connected to an exhaust duct 13, and the interior of the exhaust duct 13 is bolted with a second fan 14, and the surface of the exhaust duct 13 is bolted with a second dustproof net 15. When the second fan 14 is turned on, the air that absorbs heat inside the body 1 is discharged through the exhaust duct 13. Since the air here is discharged outward, there is no need to set a dehumidification function here.

[0026] The extrusion structure 11 includes a drive motor 111, a transmission column 112 and a vertical plate 113. The drive motor 111 and the vertical plate 113 are both bolted to the bottom of the inner wall of the body 1. The transmission column 112 is rotatably connected to the surface of the vertical plate 113. The output shaft of the drive motor 111 is connected to the transmission column 112 through a gear transmission. The extrusion structure 11 also includes a crankshaft 114 and a drive rod 115. The bottom end of the crankshaft 114 is rotatably connected to the bottom of the inner wall of the body 1, and the upper end of the crankshaft 114 passes through the inner side of the air outlet cover 10. The crankshaft 114 is connected to the through-hole of the air outlet cover 10 through a bevel gear transmission, and the transmission column 112 is connected to the crankshaft 114 through a bevel gear transmission at one end away from the drive motor 111. The drive rod 115 is hinged to the crankshaft 114. A movable rod 117 is provided below the surface of the vertical channel 12, and the movable rod 117 is slidably connected to the through-hole of the vertical channel 12. One end of the movable rod 117 extends to the inner side of the air inlet cylinder 2, and the other end of the movable rod 117 is bolted to the connector 116. , and the driving rod 115 and the connecting piece 116 are hinged to each other. When the sponge block 17 continues to absorb water, a certain amount of water accumulates inside it. The driving motor 111 is turned on, and its output shaft drives the transmission column 112 to rotate through the gear. Then the transmission column 112 drives the crankshaft 114 to rotate through the bevel gear. The top of the crankshaft 114 drives the long column 8 to rotate through the bevel gear. The long column 8 drives the box body 7 to rotate, so that different sponge blocks 17 rotate to the bottom and close to the movable rod 117. At the same time, the crankshaft 11 The movable rod 117 is driven to reciprocate by the driving rod 115 and the connecting member 116. The movable rod 117 reciprocates along the penetration of the vertical channel 12 and repeatedly squeezes the sponge block 17. Drain holes 118 are also formed on the periphery of the box body 7. After squeezing the sponge, water is discharged into the interior of the vertical channel 12 through the drainage holes 118 and then discharged through the vertical channel 12, thereby squeezing and draining water and preventing the sponge block 17 from malfunctioning due to water accumulation. The sponge block 17 is arranged in a fan shape.
