Multiple fins 13 are fixedly connected between the heat exchange tube 12 and the inner wall of the frame 11. It also includes a support 14, with multiple push rods 15 fixedly connected to the side of the support 14 near the fins 13. Multiple sets of brush bristles 16 are fixedly attached to the surface of each push rod 15. A moving assembly capable of driving the support 14 to move is provided on the frame 11. The brush bristles 16 are made of an elastic material. The assembly includes a motor 21, a lead screw 22, and a connecting seat 23. The connecting seat 23 is fixedly connected to the bracket 14, the motor 21 is fixedly connected to the frame 11, the lead screw 22 is fixedly connected to the output end of the motor 21, and the lead screw 22 passes through the connecting seat 23 and is connected to it through a lead screw ball nut pair. A guide rod 31 is fixedly connected to the side of the frame 11, and a sliding seat 32 is fixedly connected to the bracket 14 at a position corresponding to the guide rod 31. The guide rod 31 passes through the sliding seat 32 and is slidably connected to it.

[0026] When dust removal is required, the motor 21 drives the lead screw 22, and the rotation of the lead screw 22 drives the connecting seat 23 to move. The connecting seat 23 drives the bracket 14 to move, and the bracket 14 causes the brush bristles 16 on the push rod 15 to move. The push rod 15 corresponds to the gap between the two fins 13. The brush bristles 16 are inserted between the fins 13 by the above-mentioned moving mechanism, which can clean and remove dust from the fins 13, thereby reducing the impact of dust accumulation on the surface of the fins 13 on the heat exchange effect.

[0027] During the movement of the bracket 14, the guide rod 31 is fixedly installed on the frame 11, and the bracket 14 is connected to the guide rod 31 through the sliding seat 32. By relying on the cooperation of the sliding seat 32 and the guide rod 31, the movement of the bracket 14 can be guided, thereby improving the stability of the movement of the bracket 14.

[0028] Furthermore, such as Figure 1-5 As shown, multiple collars 43 slide on the surface of the push rod 15. The collars 43 are located on the side of the bristles 16. A rod body 44 is fixedly connected to the collar 43. A spring telescopic rod 41 is fixedly connected to the side of the frame 11 near the bracket 14. A connecting frame 42 is fixedly connected to the end of the spring telescopic rod 41 away from the frame 11. A pull rope 45 is fixedly connected to the end of the rod body 44. The end of the pull rope 45 is fixedly connected to the connecting frame 42.

[0029] In use, the side of the frame 11 is connected to the connecting frame 42 via a spring telescopic rod 41. During the movement of the bracket 14, the connecting frame 42 is supported by the telescopic rod. The connecting frame 42 is connected to the rod body 44 via a pull rope 45. The rod body 44 drives the collar 43 to slide. The collar 43 pulls the bristles 16, thereby opening the bristles 16, which facilitates cleaning of the fins 13. When resetting, the elastic material bristles 16 retract, and the collar 43 resets, thereby reducing the space occupied by the bristles 16 and reducing its impact on airflow.

[0030] Furthermore, such as Figure 1-5 As shown, a dust cover 5 is fitted on the surface of the lead screw 22. One end of the dust cover 5 is fixed to the side wall of the connecting seat 23, and the end of the dust cover 5 away from the connecting seat 23 is fixed to the frame 11. A heat insulation shell 6 is fixed to the frame 11, and the motor 21 is located inside the heat insulation shell 6.

[0031] In use, the dust cover 5 covers the surface of the lead screw 22, which reduces the amount of dust falling on the surface of the lead screw 22. The heat insulation shell 6 is used to insulate the motor 21, thereby reducing the impact of high-temperature flue gas on the motor 21.

[0032] Example 2

[0033] The moving component includes an electric actuator 15, which is mounted on the frame 11, and the output end of the electric actuator 15 is fixedly connected to the bracket 14.

[0034] Working principle: When dust removal is required, the motor 21 drives the lead screw 22. The rotation of the lead screw 22 drives the connecting seat 23 to move. The connecting seat 23 drives the bracket 14 to move. The bracket 14 causes the brush bristles 16 on the push rod 15 to move. The push rod 15 corresponds to the gap between the two fins 13. The brush bristles 16 are inserted between the fins 13 by the above-mentioned moving mechanism, which can clean and remove dust from the fins 13, thereby reducing the impact of dust accumulation on the surface of the fins 13 on the heat exchange effect.

[0035] During the movement of the bracket 14, the guide rod 31 is fixedly installed on the frame 11. The bracket 14 is connected to the guide rod 31 through the sliding seat 32. The sliding seat 32 and the guide rod 31 cooperate to guide the movement of the bracket 14 and improve the stability of the movement of the bracket 14. In use, the side of the frame 11 is connected to the connecting frame 42 through the spring telescopic rod 41. During the movement of the bracket 14, the connecting frame 42 is supported by the telescopic rod. The connecting frame 42 is connected to the rod body 44 through the pull rope 45. The rod body 44 drives the collar 43 to slide, and the collar 43 pulls the bristles. 16, thus allowing the bristles 16 to open, making it easier to clean the fins 13. During reset, the elastic material bristles 16 retract, and the collar 43 resets, thereby reducing the space occupied by the bristles 16 and thus reducing its impact on airflow. During use, a dust cover 5 is provided, which covers the surface of the lead screw 22. The dust cover 5 reduces dust falling on the surface of the lead screw 22. A heat insulation shell 6 is provided to insulate the motor 21, thereby reducing the impact of high-temperature flue gas on the motor 21.
