[0002] A cooling tower is a device that uses water as a circulating coolant, absorbing heat from a system and discharging it into the atmosphere to lower the water temperature. It is an evaporative heat dissipation device that uses the principles of evaporative heat dissipation, convection heat transfer, and radiation heat transfer to dissipate waste heat generated in industry or refrigeration and air conditioning to lower the water temperature.

However, in cold northern regions, when the cooling tower is shut down, water stains will remain inside the cooling tower, which may cause the internal components of the cooling tower to freeze due to the influence of external cold air, causing serious surface ice on the internal components and hindering operation, affecting the normal operation of the cooling tower.
