The working principle of the cooling tower is to recycle water as coolant, absorb indoor heat from the equipment and discharge it into the atmosphere, and complete the work with the equipment of lowering water temperature. Among them, the cold air is produced by the cold and heat exchange between water and air, and the vapor volatilization takes part of the heat to reach the principles of vapor heat dissipation, convective heat transfer and radiation heat transfer. It disperses the heat generated in industry or refrigeration and air conditioning, and evaporates and radiates heat dissipation devices used to reduce the water temperature to ensure the normal operation of the system. The device looks like a tower, so it is named cooling tower. 。

Cooling tower is a comprehensive product of dynamics, thermodynamics, fluid science, chemistry, biology, materials science, static, dynamic structural mechanics, processing technology and other disciplines.

Because of the location of the motor outside the cooling tower wind drum, there is no space limitation. The diameter, number, shape and angle of the impeller of the external turbine can be changed according to the actual situation of customers. It is convenient to increase the torque to improve the conversion efficiency. The design of different flow and pressure systems can achieve better and better transmission conversion ratio, and achieve the fan speed of cooling tower is greater than or equal to the fan speed driven by the original motor. External turbines take the shape of snails. Biological snails are used to reduce the impact and vibration rate of circulating water.
