[0019] Compared with the prior art, the present utility model provides a fin structure for a marine heat exchanger, which has the following beneficial effects:
[0020] (1) For the fin structure of the marine heat exchanger, the hot gas discharged through the exhaust pipe first enters the inside of the sleeve and is discharged from the discharge holes of the sleeve. Then, through the blades, using the principle of hot gas rising, the hot gas drives the sleeve to rotate as a whole through the blades. The sleeve drives the first cleaning brush and the second cleaning brush to rotate, cleaning the upper and lower surfaces of the fin body. The hot gas exchanges heat through the fin body and is reused, which can automatically clean both sides of the fin body and prevent the heat exchange efficiency from being affected due to excessive soot accumulation on the fin body.
[0021] (2) For the fin structure of the marine heat exchanger, when maintenance of components is required, the electric telescopic rod drives the long board and the connecting block to lift, and at the same time drives the sleeve to lift. The sleeve slides inside the exhaust pipe, and after driving the fin body outside the exhaust pipe, maintenance can be conveniently carried out, which is more convenient for maintenance and saves maintenance costs and time.

A second cleaning brush 27 is fixedly installed at the bottom of the second connecting rod 25. The bottom of the fin is cleaned by the second cleaning brush 27.
[0030] Furthermore, the first cleaning brush 23 fits against the top of the fin body 4, and the second cleaning brush 27 fits against the bottom of the fin body 4. An air outlet is provided on the inner wall of the sleeve 21 on one side of the blade 22. The sleeve 21 is rotatably installed on the top of the fin body 4. The other end of the third connecting rod 26 away from the second connecting rod 25 is fixedly installed on the inner wall of the fin body 4. The first cleaning brush 23 is slidably installed on the inner wall of the exhaust pipe 1.
[0031] Specifically, the hot air discharged through the exhaust pipe 1 first enters the inside of the sleeve 21 and is discharged from the discharge holes of the sleeve 21 and then passes through the blade 22. Using the principle of hot air rising, the hot air drives the overall rotation of the sleeve 21 through the blade 22. The first cleaning brush 23 and the second cleaning brush 27 are driven to rotate by the sleeve 21 to clean the upper and lower surfaces of the fin body 4. The hot air exchanges heat through the fin body 4 and is reused, enabling automatic cleaning of both sides of the fin body 4 and preventing the heat exchange efficiency from being affected due to excessive accumulation of soot on the fin body 4.
[0032] Please refer to Figures 1-4 and, on the basis of Embodiment 1, further obtain Embodiment 2:

[0035] Specifically, when maintenance of the components is required, the electric telescopic rod 31 drives the long plate 33 and the connecting block 34 to move up and down, and at the same time drives the sleeve 21 to move up and down. The sleeve 21 slides inside the exhaust pipe 1, and after driving the fin body 4 outside the exhaust pipe 1, maintenance can be conveniently carried out, which is more convenient for maintenance and saves maintenance costs and maintenance time.
[0036] In summary, for the fin structure of a marine heat exchanger, first, the hot gas discharged through the exhaust pipe 1 enters the interior of the sleeve 21 and is discharged from the discharge holes of the sleeve 21. Then, through the blades 22, using the principle of hot gas rising, the hot gas drives the overall rotation of the sleeve 21 through the blades 22. The sleeve 21 drives the first cleaning brush 23 and the second cleaning brush 27 to rotate, cleaning the upper and lower surfaces of the fin body 4. The hot gas exchanges and reuses heat through the fin body 4. When maintenance of components is required, the electric telescopic rod 31 drives the long plate 33 and the connecting block 34 to lift, and at the same time drives the sleeve 21 to lift. The sleeve 21 slides inside the exhaust pipe 1, and after driving the fin body 4 outside the exhaust pipe 1, maintenance can be conveniently carried out.
