An improved scraper includes vertical plates and rings. The upper and lower sides of the vertical plates are respectively fixed to the outer walls of the rings. A scraper structure is connected to the inner wall of each ring. The scraper structure includes a rod and a cylinder. The outer end of the rod is rotatably connected to the inner wall of the ring, and the outer wall of the rod is fixed to the inner wall of the cylinder. This ensures that the left scraper remains in contact with the outer wall of the square heat pipe. After the right scraper moves to the end of the square heat pipe, the vertical plates are pushed to the left. At this time, the vertical plates, together with the left rod and cylinder, move the left scraper to the left, keeping it in contact with the square heat pipe. The left scraper and the vertical plates are then subjected to force, which removes the scale layer from the outer wall of the square heat pipe, thus cleaning the surface of the square heat pipe. This scraper reduces the cost of cleaning heat exchange pipes, reduces labor, and improves the cleaning effect.
