Design And Application of Cooling Tower Nozzles

Design and Application Analysis of Cooling Tower Nozzle

The cooling tower nozzle is a key component in the cooling tower system that achieves uniform water distribution and efficient heat transfer. Its main function is to evenly spray circulating water onto the surface of the fill, forming small water droplets or water films, thereby increasing the contact area between water and air and improving the efficiency of evaporative cooling.

Reasonable design of the cooling tower nozzle is of great significance for improving the overall performance of the cooling tower, reducing energy consumption, and decreasing operation and maintenance costs.
