Description

Technical Field

[0001] The present invention relates to the technical field of finned heat exchangers, and more specifically, it relates to an adjustable finned heat exchanger. Background Art

[0002] A finned heat exchanger is an efficient heat exchange device. By installing fins on the surface of the base tube, the heat transfer area is significantly increased, and the heat exchange efficiency is improved. Its core structure includes a base tube and densely arranged fins. Common materials are copper, aluminum or stainless steel, taking into account both thermal conductivity and corrosion resistance. The fin designs are diverse (such as straight, corrugated, serrated), which can optimize the turbulence effect according to the airflow characteristics and are suitable for heat exchange scenarios between gas-liquid or gas-gas. This device is widely used in fields such as air conditioner condensers, automotive radiators, and industrial waste heat recovery systems, and has the characteristics of compact structure, high heat transfer coefficient, and low energy consumption.

[0003] A patent application with the publication number CN119665690A discloses an adjustable finned heat exchanger, including a housing. Air passing ports are opened on both sides of the housing. A plurality of heat exchange modules for heat transfer are provided in the housing. The heat exchange module in the middle part is fixed to the housing, and the remaining heat exchange modules are slidably connected to the housing through a guiding mechanism. The distance between the heat exchange modules can be adjusted by an adjusting mechanism, and the heat exchange modules are connected to each other through a second bellows. Fans are fixed to the inner sides of both ends of the housing by bolts, and air guiding and adjusting mechanisms for guiding the wind direction are provided on the inner sides of both ends of the housing. Through the movable heat exchange modules, the water droplets can be assisted to shake, so that the water droplets fall off from the heat exchange modules, reducing the retention time of the water droplets on the heat exchange modules, reducing the corrosion of the heat exchange modules by the water droplets, and improving the service life of the heat exchanger.

[0004] During the use of the above device, although the water droplets and wind direction on the heat exchanger can be adjusted by shaking, and the gas in the heat exchanger can be heated or cooled, when introducing some gases with oil stains and dust such as ambient air or blast furnace flue gas, it will cause dust and oil stains to accumulate at the bottom of the fins, resulting in the accumulation of oil stains and dust at the bottom of the fins, making the formed water droplets and oil stains unable to drip, causing the problem of poor heat dissipation effect.

Detailed implementation manners

[0019] Now, the subject matter described herein will be discussed with reference to example embodiments. It should be understood that discussing these embodiments is only to enable those skilled in the art to better understand and thus implement the subject matter described herein. Without departing from the scope of protection of the content of this specification, changes can be made to the functions and arrangements of the elements discussed. Each example can omit, substitute, or add various processes or components as needed. Additionally, the features described relative to some examples can also be combined in other examples.

[0020] As Figures 1 to 3As shown in the figure, an adjustable finned heat exchanger according to an embodiment of the present invention includes a heat exchange box 1. Symmetrically arranged first heat exchange connection blocks 12 and second heat exchange connection blocks 14 are fixedly installed at both ends of the heat exchange box 1. A heat exchange connection port 121 is fixedly installed at the end of the first heat exchange connection block 12. A bottom support frame 11 is fixedly installed at the bottom of the heat exchange box 1. A number of heat dissipation fin plates 13 are arranged inside the heat exchange box 1. A scraping and adjusting device 2 is arranged inside the heat exchange box 1 on the side close to the heat exchange connection port 121. A conveying device 3 is arranged at the bottom of the heat exchange box 1 on the side far from the heat exchange connection port 121. The scraping and adjusting device 2 is used to clean the oil stains and dust on the outside of the heat dissipation fin plates 13 at the lower part of the heat exchange box 1. The conveying device 3 is used to clean the outside of the scraping and adjusting device 2; As Figures 4 to 8 shown, the scraping and adjusting device 2 includes a first threaded rod 21, a scraping member 22, a connecting member 23, and an adjusting member 26. The first threaded rod 21 and the connecting member 23 are rotatably installed at the lower part of the heat exchange box 1. A plurality of scraping members 22 are arranged between the first threaded rod 21 and the connecting member 23. The plurality of scraping members 22 are used to clean the oil stains on the heat dissipation fin plates 13 at the lower part of the heat exchange box 1. The adjusting member 26 is rotatably installed on the side of the heat exchange box 1. The adjusting member 26 includes first adjusting blocks 261 linearly arranged and rotatably installed on the inner wall of the heat exchange box 1. An adjusting rotating wheel 262 is fixedly installed on the side of the first adjusting block 261. An adjusting belt 263 is arranged on the outer wall of the adjusting rotating wheel 262. The rotation of the adjusting member 26 is used to adjust the direction of the wind blowing into the heat exchange box 1.

[0021] It should be noted that a pipe is internally connected to the heat dissipation fin plate 13 on the heat exchange box 1, and the pipes on multiple heat dissipation fin plates 13 are interconnected. The heat exchange connection port 121 on the first heat exchange connection block 12 is connected to the exhaust port of the blast furnace gas. When the blast furnace gas comes into contact with the heat dissipation fin plate 13, the water flowing in the pipe inside the heat dissipation fin plate 13 can be heated, thereby cooling the blast furnace gas when it passes through the inside of the heat exchange box 1. The cooled blast furnace gas is discharged from the position of the second heat exchange connection block 14. Since there is dust and oil in the blast furnace gas, when the blast furnace gas passes through the inside of the heat exchange box 1 and conducts heat to the heat dissipation fin plate 13, dust and oil may accumulate on the heat dissipation fin plate 13 after the temperature drops. The oil will flow to the bottom of the heat dissipation fin plate 13 under the action of gravity. If there is too much dust adhering to the bottom, it may cause the heat dissipation fin plate 13 to be unable to absorb too much heat, resulting in the problem of deformation of the heat dissipation fin plate 13. Therefore, a first threaded rod 21, a scraping member 22, a connecting member 23, and an adjusting member 26 are provided at the lower part of the heat exchange box 1. When the motor drives the first threaded rod 21 to rotate, the scraping member 22 can be driven to move along the length direction of the heat exchange box 1, thereby cleaning the heat dissipation fin plate 13 at the lower part of the heat exchange box 1. The connecting member 23 can limit multiple scraping members 22. The number of scraping members 22 corresponds to the number of fins on the heat dissipation fin plate 13, preventing too much dust and oil from adhering to the heat dissipation fin plate 13 at the lower part of the heat exchange box 1 and causing the problem of high-temperature deformation of the heat dissipation fin plate 13. Since the blast furnace gas will cool down when passing through the inside of the heat exchange box 1, and the hot air is located above and the cold air is located below. If the blast furnace gas is continuously blown into the inside of the heat exchange box 1, it may cause the temperature of the heat dissipation fin plate 1 at the upper part of the inside of the heat exchange box 1 to be relatively high, resulting in the problem of deformation of the heat dissipation fin plate 13. Therefore, an adjusting member 26 is provided inside the heat exchange box 1. Multiple first adjusting blocks 261 can rotate to adjust the direction, so that the blast furnace gas blown into the inside of the heat exchange box 1 can blow to the lower part of the heat exchange box 1, thereby maintaining the temperature balance inside the heat exchange box 1 and preventing the heat of the heat dissipation fin plate 13 at the top of the heat exchange box 1 from being too high, causing the problem of fin deformation. The blowing direction of the blast furnace gas can be adjusted by adjusting the adjusting member 26 when the blast furnace gas enters the inside of the heat exchange box 1.

[0022] As Figures 3 to 4 shown, the scraping and adjusting device 2 includes a turning member 24 rotatably installed on one side of the lower part of the heat exchange box 1 close to the connecting member 23. There is a frictional force between the turning member 24 and the heat exchange box 1. A limiting member 25 is threadedly installed on the outside of the turning member 24, and the limiting member 25 is installed on the side of the scraping member 22.

[0023] It should be noted that a steering member 24 is provided inside the heat exchange box 1, and the steering member 24 is connected to the scraping member 22. When the first threaded rod 21 drives the scraping member 22 to move, the direction of the scraping member 22 can be adjusted. When the first threaded rod 21 rotates to drive the scraping member 22 to move towards the second heat exchange connection block 14, the steering member 24 plays a damping role, thereby driving the scraping member 22 to rotate, so that the scraping member 22 is located below the first threaded rod 21. A plurality of scraping members 22 are combined to form a plate to stir the oil stains and dust on the bottom of the heat exchange box 1. When the first threaded rod 21 rotates to drive a plurality of scraping members 22 to approach the first heat exchange connection block 12, the oil stains and dust accumulated at the bottom of the heat exchange box 1 are stirred, so that the dust at the bottom moves towards the conveying device 3, thereby transporting the dust and oil stains into the conveying device 3, and the conveying device 3 transports the dust to the outside of the heat exchange box 1.

[0024] As Figures 4 to 6 shown, a threaded moving block 211 is threadedly installed on the outer wall of the first threaded rod 21, a scraping member 22 is rotatably installed on the side of the threaded moving block 211. The scraping member 22 includes a second mounting block 222 rotatably installed on the side of the threaded moving block 211. A first mounting block 221 is fixedly installed on the side of the second mounting block 222. A top connecting column 225 is fixedly installed on the top of the first mounting block 221. A first scraping structure 223 and a second scraping structure 224 are rotatably installed on the outside of the top connecting column 225. The first scraping structure 223 and the second scraping structure 224 are used to clean the heat dissipation fin plate 13 at the lower part of the heat exchange box 1.

[0025] It should be noted that a top connecting column 225 is provided on the first mounting block 221. A first scraping structure 223 and a second scraping structure 224 are provided inside the top connecting column 225. A torsion spring is provided between the first scraping structure 223 and the second scraping structure 224, so that the first scraping structure 223 and the second scraping structure 224 are in the same plane under normal conditions. When the first scraping structure 223 and the second scraping structure 224 contact the fins on the heat dissipation fin plate 13, they can rotate, thereby driving the second scraping structure 224 to scrape the heat dissipation fin plate 13 at the bottom to prevent oil stains and dust from adhering. When the first scraping structure 223 and the second scraping structure 224 rotate to the bottom, the oil stains and dust at the bottom of the heat exchange box 1 can be cleaned.

[0026] As Figures 5 to 6As shown, the second scraping structure 224 includes a first scraping block 2241 rotatably mounted on the top of the top connecting column 225. A scraping block placement groove 2242 is provided inside the first scraping block 2241. A second scraping block 2243 is slidably mounted inside the scraping block placement groove 2242. A first ejector pin 2244 and a second ejector pin 2245 are fixedly mounted on the side of the second scraping block 2243. A first scraping block limiting plate 2246 is fixedly mounted inside the first scraping block 2241. A scraping block spring 2247 is fixedly mounted on the side of the first scraping block limiting plate 2246. A second scraping block limiting plate 2248 is fixedly mounted at the end of the first ejector pin 2244. The second scraping block limiting plate 2248 is used to limit the scraping block spring 2247. A disc cam is provided on the top of the top connecting column 225. The end of the second ejector pin 2245 cooperates with the disc cam on the top of the top connecting column 225.

[0027] It should be noted that a top connecting column 225 is provided on the top of the first mounting block 221, and a disc cam is provided on the top of the top connecting column 225. Therefore, when the first scraping structure 223 and the second scraping structure 224 approach each other, the second ejector pin 2245 jacks up the second scraping block 2243, and the jacked-up second scraping block 2243 can clean the bottom of the heat dissipation fin plate 13 to prevent oil stains and dust from accumulating on the bottom of the heat dissipation fin plate 13 without dripping, resulting in poor heat dissipation effect. When the first scraping structure 223 and the second scraping structure 224 rotate to the bottom, the first scraping structure 223 and the second scraping structure 224 are in the same plane. Under the action of the scraping block spring 2247, the second scraping block 2243 can be driven to retract into the first scraping block 2241, so that a plurality of second scraping structures 224 and the first scraping structure 223 are in contact with each other. Then, a plurality of second scraping structures 224 and the first scraping structure 223 are in contact with each other to form a flat plate to stir the oil stains and dust on the bottom of the heat exchange box 1.

[0028] As Figures 4 to 6 As shown, a connecting member 23 is rotatably mounted on the side of the second mounting block 222. The connecting member 23 includes a first sliding rod 231 rotatably mounted inside the heat exchange box 1. A first connecting block 232 is slidably mounted on the outside of the first sliding rod 231. The lower part of the first connecting block 232 is rotatably mounted on the side of the second mounting block 222.

[0029] It should be noted that the first sliding rod 231 and the first connecting block 232 are used to drive a plurality of scraping members 22 to move along the length direction of the heat exchange box 1, so that when the scraping members 22 move, they correspond to the fins on the heat dissipation fin plate 13.

[0030] As Figure 7As shown, the steering member 24 includes a second threaded rod 241 rotatably mounted at the lower part of the heat exchange box 1. An external thread of the second threaded rod 241 is provided with a first steering block 242. A steering groove 243 is arranged inside the first steering block 242. A steering protrusion 244 is slidably mounted inside the steering groove 243. An end of the steering protrusion 244 is fixedly mounted with a steering column 245. A side part of the steering column 245 penetrates through a lower part of the first connection block 232 and is fixedly mounted with the second mounting block 222. Symmetrically arranged steering limit blocks 246 are fixedly mounted at a lower part of the first connection block 232. The steering limit blocks 246 are used for limiting the steering column 245.

[0031] It should be noted that the connection position between the second threaded rod 241 and the heat exchange box 1 is a friction connection. Therefore, when the first threaded rod 21 rotates to drive the plurality of scraping members 22 to move, the second threaded rod 241 will also rotate accordingly. An outer wall of the second threaded rod 241 is provided with the first steering block 242, so that when the first steering block 242 moves, it is stressed, thereby driving the steering column 245 to rotate. The rotation of the steering column 245 can drive the scraping members 22 to rotate, so that the directions of the scraping members 22 are changed. The steering limit blocks 246 can prevent the scraping members 22 from rotating excessively.

[0032] As Figure 7 shown, the limiting member 25 includes a first spring mounting block 251 and a second spring mounting block 252 fixedly mounted at a lower part of the first connection block 232. Connecting springs 253 are fixedly mounted on side parts of the first spring mounting block 251 and the second spring mounting block 252. A spring fixing block 254 is fixedly mounted on an outer part of the steering column 245. The connecting springs 253 are fixedly mounted with the spring fixing block 254.

[0033] It should be noted that the design of the first spring mounting block 251, the second spring mounting block 252 and the connecting springs 253 can adjust the direction when the first threaded rod 21 drives the scraping members 22 to move, and prevent the scraping members 22 from getting stuck at a point.

[0034] As Figure 8 shown, an adjusting wheel 264 is fixedly mounted on an outer part of the bottom adjusting rotary wheel 262. An adjusting handle 265 is fixedly mounted on an outer part of the adjusting wheel 264.

[0035] It should be noted that the rotation of the plurality of first adjusting blocks 261 can adjust the direction, so that the blast furnace flue gas blown into the heat exchange box 1 can blow the lower part of the heat exchange box 1, thereby maintaining the temperature balance inside the heat exchange box 1, and preventing the heat of the heat dissipation fin plate 13 at the top of the heat exchange box 1 from being too high, resulting in the problem of fin deformation.

[0036] As Figure 9As shown, the conveying device 3 includes a conveying trough 31 fixedly installed at the bottom of the heat exchange tank 1. Inside the conveying trough 31, a conveying member 32 and a cleaning member 33 are rotatably installed. The conveying member 32 includes a moving rod 322 rotatably installed inside the conveying trough 31. At the end of the moving rod 322, a first gear 321 is fixedly installed. On the outer wall of the moving rod 322, a conveying reel 323 is fixedly installed. The cleaning member 33 includes a cleaning rod 332 rotatably installed above the conveying trough 31. On the outer wall of the cleaning rod 332, a number of cleaning brushes 333 are fixedly installed. At the end of the cleaning rod 332, a second gear 331 is fixedly installed. The second gear 331 meshes with the first gear 321. The cleaning brushes 333 are used to clean the scraping member 22, and the conveying reel 323 is used to clean the sludge inside the heat exchange tank 1.

[0037] It should be noted that when the scraping member 22 moves above the conveying trough 31, driving the first gear 321 to rotate with a motor can cause the cleaning rod 332 and the cleaning brushes 333 to rotate. The rotation of the cleaning rod 332 and the cleaning brushes 333 can clean the scraping member 22, and the rotation of the moving rod 322 and the conveying reel 323 can convey the dust and oil stains stirred at the bottom of the heat exchange tank 1, thereby preventing the problem of dust and oil stain accumulation at the bottom of the heat exchange tank 1.

[0038] As Figure 9 shown, a conveying seal port 34 is provided on the side of the conveying trough 31, and the diameter of the conveying reel 323 is the same as the diameter of the conveying seal port 34.

[0039] It should be noted that a conveying seal port 34 is provided on the side of the conveying trough 31, and the diameter of the conveying seal port 34 is the same as the diameter of the conveying reel 323, which can seal the inside of the heat exchange tank 1 while rotating.

[0040] The above describes the embodiments of this embodiment, but this embodiment is not limited to the above specific implementation manners. The above specific implementation manners are merely illustrative and not restrictive. Under the inspiration of this embodiment, those of ordinary skill in the art can also make many forms, all of which fall within the protection scope of this embodiment.
