[0035] When the cooling water pipe 4 needs cleaning, the drain port 42 is opened, and the cleaning water in the water storage tank 8 is continuously sprayed onto the inner wall of the cooling water pipe 4 through the first high-pressure nozzle 62. The inner wall of the cleaning pipe 61 is flushed under high pressure to remove the dirt attached to the cooling water pipe 4. The wastewater is discharged out of the pipe through the drain port 42. At the same time, the cleaning pipe 61 installed outside the cooling water pipe 4 can also enhance the strength and corrosion resistance of the cooling water pipe 4, prevent the cooling water pipe 4 from being corroded by external ultraviolet rays, oxidation, chemicals, etc., extend the service life of the cooling water pipe 4, effectively reduce the risk of water leakage of the cooling water pipe 4, improve the safety of the air conditioning cooling water system, and enable it to adapt to more diverse environments.
