[0019] See also Figure 1-3 As shown, a closed high-speed precision fin device includes a shell 1, on which a cold medium feed pipe 2, a cold medium discharge pipe 3, a hot medium feed pipe 4 and a hot medium discharge pipe 5 are respectively installed, a fin bundle structure is installed inside the shell 1, and the fin bundle structure includes five fins 6, and the five fins 6 are respectively a first gasket 7, a first plate 8, a second gasket 9, a second plate 10 and a third gasket 11, a limiting flow frame 12 is arranged in the fin 6, and a texture 13 is arranged on the side wall of the fin 6 in the limiting flow frame 12, and a spoiler bridge is arranged on the side wall of the fin 6 The four ends of the fin 6 are respectively provided with a cold medium feed pipe port 15, a cold medium discharge pipe port 16, a hot medium feed pipe port 17 and a hot medium discharge pipe port 18. The cold medium feed pipe port 15 and the cold medium discharge pipe port 16 of the first plate 8 and the second gasket 9 are connected by a conduit. The cold medium feed pipe port 15 and the cold medium discharge pipe port 16 of the second plate 10 and the third gasket 11 are connected by a conduit. The hot medium feed pipe port 17 and the hot medium discharge pipe port 18 of the first gasket 7 and the first plate 8 are connected by a conduit. The heat medium feed pipe port 17 of the gasket 9 and the heat medium discharge pipe port 18 of the second plate 10 are connected by a conduit; when working, the existing fin 6 has a simple structure, which makes the heat medium flow rate faster and its cooling time is shorter, resulting in poor heat dissipation effect of the heat medium. By introducing cold medium into the cold medium feed pipe 2, the cold medium can flow along the lines 13 on the first gasket 7, the second gasket 9 and the third gasket 11, and then flow out from the cold medium discharge pipe 3. At the same time, the hot medium is introduced into the hot medium feed pipe 4, and the hot medium flows along the first plate 8 and the texture 13 on the second plate 10, and then flow out from the heat medium discharge pipe 5. This structure makes the cold and hot fluid flow channels arranged alternately, so that the cold fluid and the hot fluid exchange heat. The material of the fin 6 is a stainless steel plate, and the texture 13 on the fin 6 is used as a flow channel. By arranging a spoiler bridge 14 on the fin 6, after the fluid passes through the texture 13, it needs to pass through the spoiler bridge 14 again. The spoiler bridge 14 blocks the cold and hot fluids, slows down the flow rate of the hot fluid, thereby extending the heat exchange time, which is beneficial to improving the heat dissipation effect of the heat medium.

The heat medium is introduced into the feed pipe 29, and the heat medium is filtered after passing through the first filter plate 25. The pure heat medium enters the shell 1 from the heat medium feed pipe 4. When the impurities in front of the first filter plate 25 are cleaned, the knob 22 is turned to drive the screw rod 21 to rotate, the screw rod 21 drives the slider 23 to rotate, the slider 23 drives the three groups of partitions 24 to move horizontally, the three groups of partitions 24 drive the first filter plate 25 and the second filter plate 26 to move horizontally, the partition 24 pushes the impurities to fall from the first discharge trough 27, and then the impurities are collected by the collection box 31, and the second filter plate 26 moves to the front side of the heat medium feed pipe 4, so that the first filter plate 25 and the second filter plate 26 are alternately filtered.

[0021] Working principle: in the process of heat dissipation of the heat medium by the existing fins 6, since the heat medium cannot be filtered, the impurities inside the heat medium are easily accumulated on the fins 6, which is easy to cause damage to the fins 6, resulting in poor protection of the fins 6. The heat medium is introduced into the feed pipe 29, and the heat medium is filtered after passing through the first filter plate 25. The pure heat medium enters the shell 1 from the heat medium feed pipe 4. When the impurities in front of the first filter plate 25 are cleaned, the knob 22 is turned to drive the screw rod 21 to rotate, and the screw rod 21 drives the slider 23 to rotate. The slider 23 drives the three groups of partitions 24 to move horizontally. The three groups of partitions 24 drive the first filter plate 25 and the second filter plate 26 to move horizontally. The partition 24 pushes the impurities to fall from the first discharge trough 27. After that, the impurities are collected by the collection box 31, and the second filter plate 26 moves to the front side of the heat medium feed pipe 4, so that the first filter plate 25 and the second filter plate 26 are alternately filtered. This structure realizes the filtration of impurities inside the heat medium and prevents the impurities inside the heat medium from accumulating on the fins. The fin 6 is damaged, which is beneficial to improve the protection of the fin 6; the existing fin 6 has a simple structure, which makes the heat medium flow faster and its cooling time is short, resulting in poor heat dissipation effect of the heat medium. By introducing cold medium into the cold medium feed pipe 2, the cold medium can flow along the lines 13 on the first gasket 7, the second gasket 9 and the third gasket 11, and then flow out from the cold medium discharge pipe 3. At the same time, the hot medium is introduced into the hot medium feed pipe 4, and the hot medium flows along the lines 13 on the first plate 8 and the second plate 10. The liquid flows along the lines 13 and then flows out from the heat medium discharge pipe 5. This structure arranges the cold and hot fluid flow channels alternately, so that the cold fluid and the hot fluid exchange heat. The fin 6 is made of stainless steel plate. The lines 13 on the fin 6 serve as flow channels. By arranging spoiler bridges 14 on the fins 6, after the fluid passes through the lines 13, it needs to pass through the spoiler bridges 14 again. The spoiler bridges 14 block the cold and hot fluids, slowing down the flow rate of the hot fluid, thereby extending the heat exchange time, which is beneficial to improving the heat dissipation effect of the heat medium.
