The refrigerant liquefies on the outer wall of the condenser pipe 7, is guided by the second fixed tube sheet 16, and the liquefied refrigerant is discharged through the refrigerant outlet pipe 21. When water enters the condenser pipe 7, the water in the connection inlet box 3 enters the condenser pipe 7, causing the impeller 10 in the condenser pipe 7 to rotate at a high speed, generating a strong disturbance to the fluid in the condenser pipe 7, thereby breaking the fluid stagnant layer on the wall of the condenser pipe 7 and changing the water flow in the condenser pipe 7 from a direct flow to a vortex flow. Under the action of the water flow, the heat transfer surface of the pipe wall is kept clean, preventing dirt from staying. When cleaning the outer wall of the condenser pipe 7, the output end of the hydraulic cylinder 19 drives the driving plate 18 to move. When the driving plate 18 moves, it pushes the first outer wall scraping frame 12, the second outer wall scraping frame 13, the third outer wall scraping frame 14, and the connecting plate 17 to move. The first outer wall scraping frame 12 drives the outer limiting sliding ring 11 to move limitedly in the condenser housing 1. The first outer wall scraping frame 12, the second outer wall scraping frame 13, and the third outer wall scraping frame 14 move on the outside of each condenser pipe 7 to scrape off impurities and dirt on the outside of the condenser pipe 7, improving the heat transfer efficiency of the condenser pipe 7 and preventing dirt from drying and affecting the heat transfer of the condenser pipe 7.
