The rotation of the motor 9 drives the first gear 8 to rotate, and the third gear 14 is rotated through the chain 16. The rotation of the third gear 14 drives the first tooth plate 17 and the second tooth plate 18 to move toward each other, so that the first push plate 19 and the second push plate 20 move toward each other. The first push plate 19 and the second push plate 20 move toward each other and drive the scraper 23 to clean the surface of the filter screen 21.
[0035] The utility model uses steps: when the tube-fin heat exchanger that can improve the heat dissipation effect is in use, the filter 21 is installed on the outside of the heat exchanger body 1, the rotation of the motor 9 drives the first gear 8 to rotate, and the third gear 14 is rotated through the chain 16, and the rotation of the third gear 14 drives the first tooth plate 17 and the second tooth plate 18 to move toward each other, so that the first push plate 19 and the second push plate 20 move toward each other, and the first push plate 19 and the second push plate 20 move toward each other and drive the scraper 23 to clean the surface of the filter 21.
