[0024] First, the integrated frame 3 is installed on the surface of the fin body 2, and the fin body 2 is connected to the pin shaft 13 in sequence through the clamping shaft 4. When the distance between the fins needs to be adjusted, the swing rod 6 is rotated, and the swing rod 6 rotates around the movable shaft 7. The swing rod 6 drives the lower truss 14 to rotate through the linkage shaft 8. At the same time, the lower truss 14 drives the upper truss 11 to rotate through the connecting shaft 17. The upper truss 11 and the lower truss 14 drive the pin shaft 13 to slide inside the slide groove 12. The upper truss 11 drives the short rod 9 through the hinge shaft 10 around the movable shaft 7. The shaft rotates, and at the same time, the upper truss 11 and the lower truss 14 drive the other groups of pins 13 to move synchronously through the connecting shaft 17, and the pins 13 drive the fin bodies 2 to move synchronously through the clamping shaft 4 to synchronously adjust the spacing between the fin bodies 2. When the spacing between the fin bodies 2 needs to be adjusted, the spacing between the fin bodies 2 can be adjusted by controlling the rotation angle of the swing rod 6, which realizes the convenient linkage adjustment of the spacing between the fins, facilitates the rapid adjustment of the fin spacing, and improves the convenience of adjustment;

[0025] The surface of the pin shaft 13 is provided with a lower truss 14, and the lower truss 14 is movably connected to the pin shaft 13;

[0026] The upper truss 11 is mounted on the surface of the pin shaft 13 above the lower truss 14, and the upper truss 11 is movably connected to the pin shaft 13. A hinge shaft 10 is installed at one end of the upper truss 11 close to the short rod 9, and the upper truss 11 is movably connected to the short rod 9 through the hinge shaft 10.

[0027] A linkage shaft 8 is installed at one end of the lower truss 14 close to the swing rod 6, and the lower truss 14 is movably connected to the swing rod 6 through the linkage shaft 8. A connecting shaft 17 is installed at the connecting ends of the lower truss 14 and the upper truss 11, and the lower truss 14 is movably connected to the upper truss 11 through the connecting shaft 17.

[0028] The fin tube body 1 is provided with a fin body 2 outside, the bottom end of each fin body 2 is provided with a clamping shaft 4, and the fin body 2 is connected to the pin shaft 13 through the clamping shaft 4, and two groups of auxiliary heating blocks 5 are installed on the side walls of the fin body 2, and multiple groups of first magnets 15 with equal spacing are installed on the side walls of the auxiliary heating blocks 5, and multiple groups of second magnets 16 with equal spacing are installed on the inner wall of the auxiliary heating blocks 5;

[0029] The auxiliary heating block 5 is fitted with the side wall of the fin body 2 and the outer wall of the fin tube body 1. Under the magnetic action of multiple groups of first magnets 15, the auxiliary heating block 5 is connected to the fin body 2. Under the magnetic action of multiple groups of second magnets 16, the second magnets 16 are connected to the fin tube body 1 to increase the contact area between the fins and the pipes, thereby improving the heat exchange effect of the fins. The magnetic force of the first magnet 15 and the second magnet 16 is smaller than the force of the swing rod 6 rotating. Therefore, when adjusting the spacing of the fin body 2, the auxiliary heating block 5 will still move with the fin body 2, thereby realizing a convenient magnetic connection to adjust the contact area, facilitating the increase of the heat exchange area of ​​the fins, and improving the heat exchange effect.

[0030] Working principle: First, install the integrated frame 3 to the surface of the fin body 2, and connect the fin body 2 with the pin shaft 13 in sequence through the clamping shaft 4. When the distance between the fins needs to be adjusted, rotate the swing rod 6, and the swing rod 6 rotates with the movable shaft 7 as the axis. The swing rod 6 drives the lower truss 14 to rotate through the linkage shaft 8, and at the same time, the lower truss 14 drives the upper truss 11 to rotate through the connecting shaft 17, and the upper truss 11 and the lower truss 14 drive the pin shaft 13 to slide inside the slide groove 12, and the upper truss 11 drives the short rod 9 to rotate with the movable shaft 7 as the axis through the hinge shaft 10. At the same time, the upper truss 11 and the lower truss 14 respectively drive the other groups of pin shafts 13 to move synchronously through the connecting shaft 17, and the pin shaft 13 drives the fin body 2 to move synchronously through the clamping shaft 4 to synchronously adjust the distance between the fin bodies 2. When the spacing between the fin bodies 2 needs to be adjusted, the spacing between the fin bodies 2 can be adjusted by controlling the rotation angle of the swing rod 6, and the auxiliary heating block 5 is fitted with the side wall of the fin body 2 and the outer wall of the fin tube body 1. Under the magnetic action of multiple groups of first magnets 15, the auxiliary heating block 5 is connected to the fin body 2, and under the magnetic action of multiple groups of second magnets 16, the second magnet 16 is connected to the fin tube body 1 to increase the contact area between the fin and the pipe, so as to improve the heat exchange effect of the fin. The magnetic force of the first magnet 15 and the second magnet 16 is smaller than the force of the swing rod 6 rotation. Therefore, when adjusting the spacing between the fin bodies 2, the auxiliary heating block 5 will still move with the fin body 2 to complete the use of the fin tube with adjustable fin spacing.
