The cooling tower is a device that uses water as a circulating coolant to absorb heat from a system and discharge it to the atmosphere to reduce the water temperature. Its cooling is to use water and air to exchange heat and cold to generate steam. The steam evaporates and takes away heat to achieve evaporation. The principle of heat dissipation, convective heat transfer and radiation heat transfer is used to dissipate the waste heat generated in industry or in refrigeration and air conditioning to reduce the water temperature. The evaporative cooling device is used to ensure the normal operation of the system. The device is generally barrel-shaped, so it is called a cooling tower.
