[0002] A cooling tower uses water as a circulating coolant, absorbs heat from a system and discharges it into the atmosphere to reduce the water temperature; its cooling is achieved by using the principle of heat exchange between water and air flow to generate steam, and the evaporation of steam takes away heat to achieve evaporation heat dissipation, convective heat transfer and radiative heat transfer, etc., to dissipate the waste heat generated in industry or refrigeration and air conditioning to reduce the water temperature, so as to ensure the normal operation of the system. The device is generally barrel-shaped, so it is called a cooling tower.

[0003] During the long-term use process, since the water quality of the water flowing in the cooling tower is not very good, some substances in the water flow will condense during the process of cooling and heating, and then scale will form on the inner wall surface of the cooling tower, which will block the subsequent cooling or pipeline, and then reduce the cooling effect.
