An adjusting block 16 is fixedly installed on one end of the drive shaft 15, and an adjusting thread 17 is provided on the outer side of the other end of the drive shaft 15. A locking nut 18 is installed on the outer thread of the adjusting thread 17, and one side of the locking nut 18 contacts the outer side of the positioning frame 11. The outer sides of the transmission gear ring 13 are symmetrically meshed. A positioning frame 20 is symmetrically fixedly installed on the side of the positioning ring 3 away from the connecting ring 5, connected to a transmission gear 19. A threaded rod 21 is provided inside the positioning frame 20, and one end of the threaded rod 21 movably passes through one side of the positioning frame 20 and is fixedly connected to the transmission gear 19.

[0023] During use, the interaction of the main housing 1, support base 2, positioning ring 3, annular rubber airbag 7, through hole 9, annular compressed airbag 8, side housing 4, connecting ring 5, annular sealing groove 6, and adjusting component 10 enables the heat exchanger housing to achieve a better sealing effect during connection, ensuring the heat exchanger can work normally and thus achieving better practicality. Furthermore, the interaction of the positioning slider 26 and positioning groove 27 enables the threaded sleeve 23 to achieve better stability during movement, thus ensuring the stable operation of the adjusting component 10.

[0024] Working principle: During operation, firstly, place the two side housings 4 on both sides of the main housing 1, ensuring that the connecting ring 5 contacts the positioning ring 3, and simultaneously align the connecting block 29 with the connecting seat 28. Then, insert the connecting bolt 30 through the thread of the connecting block 29 into the interior of the connecting seat 28 to fix the connecting ring 5 and the positioning ring 3, thus fixing the side housing 4 to the end of the main housing 1. At this time, the annular rubber airbag 7 is located inside the annular sealing groove 6. Then, hold the adjusting block 16 to keep the drive shaft 15 stationary, then loosen the locking nut 18 to release the positioning of the drive shaft 15. Then, rotate the adjusting block 16 to drive the drive shaft 15 to rotate. The drive shaft 15 drives the drive gear 14 to rotate, which in turn drives the transmission gear ring 13 to rotate outside the positioning bearing 12. The transmission gear ring 13 drives the transmission gear 19 to rotate, which in turn drives the threaded rod 21 to rotate. The threaded rod 21 drives the threaded sleeve 23 to move, and the threaded sleeve 23 drives the positioning slider 26 to move in the positioning groove 27. The internal sliding mechanism ensures better stability of the threaded sleeve 23 during movement. Simultaneously, the threaded sleeve 23 drives the movable seat 24 to move outwards on the threaded rod 21. The movable seat 24 then drives the movable ring 25 to move, compressing the annular compression bladder 8. Under pressure, the air inside the annular compression bladder 8 is transported through the through hole 9 to the interior of the annular rubber bladder 7. The increased air volume causes the annular rubber bladder 7 to expand, making the outer side of the annular rubber bladder 7 in close contact with the inner wall of the annular sealing groove 6, sealing the gap between the connecting ring 5 and the positioning ring 3. Then, the rotation of the adjusting block 16 is stopped, and the adjusting block 16 is held to keep the drive shaft 15 stationary. The locking nut 18 is then tightened to reposition the drive shaft 15, and the adjusting block 16 is released. This ensures a better sealing effect during connection of the heat exchanger shell during use, guaranteeing normal operation of the heat exchanger and improving its practicality.
