Description

Technical Field

[0001] This utility model relates to the field of plate-fin heat exchange technology, specifically a plate-fin heat exchanger. Background Technology

[0002] Plate-fin heat exchangers typically consist of baffles, fins, seals, and guide vanes. Fins, guide vanes, and seals are placed between adjacent baffles to form a sandwich layer, called a channel. These sandwich layers are stacked according to different fluid flow patterns and brazed together to form a plate bundle, which is the core of the plate-fin heat exchanger.

[0003] A search revealed an existing patent (publication number: CN216011367U) disclosing a plate-fin heat exchanger, relating to the technical field of plate-fin heat exchangers. It includes a mounting plate with an upper partition slidably connected to it, a lower partition slidably connected to it, fins fixedly mounted on the lower partition, a heat exchange frame fixedly mounted on the mounting plate, auxiliary heat exchange components mounted on the heat exchange frame, and a fixed frame fixedly mounted on the left side of the heat exchange frame, with a vibration component mounted on the fixed frame. In this plate-fin heat exchanger, the upper partition, fins, and lower partition are positioned between movable components. Through the auxiliary heat exchange component and the vibration component, a transmission rod rotates, driving a rack to reciprocate up and down. This rack drives the upper partition, fins, and lower partition to vibrate up and down, causing the gas inside the upper partition, fins, and lower partition to move, thereby improving the heat exchange efficiency of the plate-fin heat exchanger.

[0004] While it improves the heat exchange efficiency of plate-fin heat exchangers, it has shortcomings. It can make the half gear mesh with the rack and pinion through the thermal expansion of the gas, but this can only be achieved when the temperature inside the plate-fin heat exchanger reaches a fixed temperature or above. It cannot set different temperatures according to different actual usage conditions. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 This utility model provides a technical solution: a plate-fin heat exchanger, including a plate-fin heat exchanger body 4. A heat dissipation enhancement mechanism 1 is provided on the outer side of the plate-fin heat exchanger body 4. The heat dissipation enhancement mechanism 1 includes two fixed cylinders 7, which are respectively fixedly connected to the front and rear surfaces of the plate-fin heat exchanger body 4. A fixed frame 9 is fixed inside the front fixed cylinder 7, and a motor 8 is fixed inside the fixed frame 9. A fan blade 10 is fixed to the output shaft of the motor 8. A movable cylinder 2 is slidably connected to the outer wall of the fixed cylinder 7. Multiple exhaust grooves 3 are opened on the outer wall of the movable cylinder 2. The fixed cylinder 7 is located away from... Two circular holes 11 are opened on one side of the plate-fin heat exchanger body 4. A tension spring 14 is fixed inside the circular hole 11. The other end of the tension spring 14 is fixedly connected to the moving cylinder 2, so that the plate-fin heat exchanger body 4 can dissipate heat. Two arc-shaped grooves 13 are opened on the outer side wall of the moving cylinder 2. An iron block 12 is fixed inside the arc-shaped groove 13. Two fixing plates 6 are fixed on the front and rear surfaces of the plate-fin heat exchanger body 4. An electromagnetic block 15 is fixed on the side of the fixing plate 6 near the arc-shaped groove 13. The electromagnetic block 15 is located inside the arc-shaped groove 13, so that the movement of the moving cylinder 2 can be controlled.

[0023] Furthermore, the plate-fin heat exchanger body 4 is equipped with a temperature control switch 5, which includes an air cylinder 26. A glass air tube 20 is fixed inside the plate-fin heat exchanger body 4. The rear end of the glass air tube 20 is fixedly connected to the front end of the air cylinder 26. A piston 25 is slidably connected inside the glass air tube 20. A connecting bracket 19 is fixed to the inner wall of the glass air tube 20. A screw 18 is screwed into the connecting bracket 19. A mounting block 21 is rotatably connected to the rear end of the screw 18. A power switch 22 is fixed to the rear end of the mounting block 21. This allows the temperature to be set. Once the temperature is reached, the power switch 22 is activated to supply power. Two fixing holes 34 are opened on the outer wall of the mounting block 21. Two fixing blocks 30 are fixed inside the fixing holes 34. A moving rod 33 is slidably connected inside the fixing blocks 30. A moving block 35 and a top block 31 are fixed to the two ends of the moving rod 33, respectively. The fixing blocks 30 and the top block 31 are fixed together. A fixed push spring 32 and a sandpaper block 36 are fixed on the side of the moving block 35 away from the moving rod 33. Two fixing grooves 24 are opened on the outer wall of the glass gas tube 20. Sandpaper strips 23 are fixed inside the fixing grooves 24. The sandpaper block 36 and the sandpaper strips 23 are in contact to increase friction and prevent the mounting block 21 and the power switch 22 from moving. A spring hole 28 is opened on the left side of the screw 18. A compression spring 29 is fixed inside the spring hole 28. The other end of the compression spring 29 is fixed to the top rod 37. The elastic force of the compression spring 29 is greater than the sum of the elastic forces of the two push springs 32. This can push the top block 31 to make the sandpaper block 36 and the sandpaper strips 23 contact. A moving ring 17 is slidably connected to the outer wall of the screw 18. A groove 16 is opened inside the moving ring 17. A pull rope 27 is fixed to the front end of the top rod 37. The other end of the pull rope 27 passes through the screw 18 and is fixedly connected to the groove 16. This can control the movement of the top rod 37.

[0024] During operation, pushing the moving ring 17 pulls the pull rope 27, which in turn moves the top rod 37 forward, placing it between the two top blocks 31. Then, pushing the spring 32 moves the top block 31, which in turn moves the moving rod 33, the moving block 35, and the sandpaper block 36. The sandpaper block 36 separates from the sandpaper strip 23. Next, rotating the moving ring 17 rotates the screw 18, which in turn moves the moving block 35, which in turn moves the power switch 22. This allows adjustment of the power switch 22 according to the required temperature and the temperature scale on the glass gas tube 20. Then, releasing the moving ring 17 compresses the spring 29, which pushes the top rod 37, which in turn compresses the top block 31. The top block 31 then moves the moving rod 33, the moving block 35, and the sandpaper block 36. 6. When the sandpaper block 36 and sandpaper strip 23 come into contact, the movement of the moving block 35 is restricted, preventing the power switch 22 from moving. The temperature inside the plate-fin heat exchanger body 4 rises, and the heat is conducted to the air cylinder 26. The air inside the air cylinder 26 expands due to the heat and enters the interior of the glass air tube 20. The gas pushes the piston 25 to move. After the set temperature is reached, the piston 25 moves and squeezes the power switch 22, which can power the motor 8 and the electromagnetic block 15 without manually turning on the power switch 22. After the electromagnetic block 15 is powered on, the electromagnetic block 15 generates a magnetic force to attract the iron block 12. The iron block 12 moves the moving cylinder 2, so that the fixed cylinder 7 will not block the exhaust groove 3. The motor 8 is powered on, and the motor 8 drives the fan blade 10 to rotate, so that the hot air inside the plate-fin heat exchanger body 4 is discharged through the front exhaust groove 3.
