[0022] The specific operation is as follows: motor two 1501 drives brush roller one 1502 to rotate, bevel gear one 1503 drives bevel gear two 1504 to rotate brush roller two 1505 and bevel gear three 1506, bevel gear three 1506 drives bevel gear four 1507 to rotate brush roller three 1508 and bevel gear five 1509, bevel gear five 1509 drives bevel gear six 1510 to rotate brush roller four 1511, brush roller one 1502, brush roller two 1505, brush roller three 1508 and brush roller four 1511 are used to clean impurities at the fluid inlet 3 and the fluid outlet 4 to ensure the normal and good operation of the plate-fin heat exchanger.

[0023] like Figures 1 to 3 As shown, isolators 5 are installed on both sides of the inside of the guide plate body 2, and a guide cavity 6 is arranged between the isolators 5, a guide hole 7 is opened on the outer surface of the guide cavity 6, and a motor 8 is installed at the middle end of the inside of the guide plate body 2, the output end of the motor 8 is connected to a rotating plate 9, and a baffle 10, a baffle 2 11 and a baffle 3 12 are arranged at the surface edge of the rotating plate 9, the area of ​​the baffle 10 is larger than the inner diameter of the guide hole 7, and the isolators 5 and the guide holes 7 are each arranged with four, a rotating shaft 13 is connected to the middle of the rotating plate 9, and a guide plate 14 is arranged on the outer side of the rotating shaft 13.
