Cooling tower is a device that uses water as circulating coolant to absorb heat from a system and discharge it to the atmosphere to reduce the water temperature; its cooling is a device that uses the flow of water and air to exchange heat and cold to generate steam, and the steam volatilization takes the heat away to achieve the principles of evaporation, convection and radiation heat transfer to disperse the waste heat produced in industry or refrigeration and air conditioning to reduce the evaporation of water temperature Cooling device, to ensure the normal operation of the system, the device is generally barrel shaped, so it is called cooling tower.

Reliability: the unique and rational design of the external turbine is installed outside the air duct of the cooling tower, which is convenient for maintenance and repair. The structure is the same as that of the traditional cooling tower motor and reducer. The mechanical noise and failure rate of the traditional motor are eliminated, and the operation is stable and reliable.
