[0002] Cooling towers, as indispensable equipment in industrial and commercial buildings, are deeply rooted in multiple fields such as thermodynamics, fluid mechanics, and materials science. The main function of a cooling tower is to release heat generated in industrial production or air conditioning systems into the atmosphere through the evaporation and cooling process of water, thereby maintaining the system's normal operating temperature. Current cooling tower cleaning methods primarily involve cleaning the main pipes, spray pipes, and nozzles to remove accumulated dust from the outdoor cooling tower casing, improving environmental hygiene. However, cleaning cooling towers solely through spraying is not suitable for removing long-term adhered dirt, resulting in inadequate cleaning effectiveness. Utility Model Content
