[0002] A closed cooling tower is a cooling device that operates through a closed circulation system, and its working principle is based on the heat exchange principle. Specifically, it transfers heat from the cooling water to the air by exchanging heat between the cooling water and the air, thereby reducing the temperature of the cooling water and achieving the cooling effect. The working process of the closed cooling tower can be subdivided into several steps such as pumping water, spraying water, absorbing heat, exhausting air, and returning water, forming a complete cycle, and the cooling tower requires a control box to control it.
