3Fan
The fan blades are made of hollow wing-shaped aluminum alloy extruded profiles. Their advantages include lightweight, low starting torque, and minimal air resistance during rotation due to the streamlined wing-shaped cross-section. There is no air vortex at the tail, resulting in low resistance and high exhaust efficiency with energy-saving benefits. As they are extruded profiles, the entire shape remains unchanged, ensuring consistent weight for each blade with high balance accuracy, no vibration, and low noise. The surface of the aluminum alloy is electrochemical treated on the production line, offering a glossy appearance, high strength, corrosion resistance, and the ability to withstand poor air conditions, with a long service life.
4) Spraying media
Wetting media is the core component of the cooling tower, and the quality of the wetting media directly affects the cooling efficiency. Therefore, the choice of media is crucial. This design uses our company's self-developed patented product.----Cellular water collection spray media.
The heat and moisture exchange process in cooling towers is conducted within the fill material of the spray cooling plates. The shape of the cooling plates directly affects the cooling efficiency and the rate of water droplets. Our company's honeycomb-shaped water collection V-wave fill material allows the cooling water to form a water film on the surface of the fill, slowly descending along the V-waves, thereby increasing the contact area between water and air. This extends the flow velocity of the water, enhances the exchange time between water and air currents, and improves the cooling efficiency.
The packing is equipped with water distributors at both the top and bottom, allowing the cooling water above to fall into the packing, ensuring an even distribution of water on both sides to the fullest extent.
The packing ends feature slanted folds with large waves, creating a honeycomb-like inwardly inclined wave pattern at the ends after assembly. This design ensures that the downward pressure of the air entering the tower does not cause water to float out, while the air exiting the packing exits diagonally upwards. Reduced wind resistance, allowing water to flow internally through the filling material by its own weight, rather than being carried away by the wind, thereby effectively ensuring water-saving effects.
In summary, our cooling tower's spray filling material is of a type that incorporates both a self-contained water collector and a water distributor, thereby reducing the tower's water loss rate from floating water.≤0.001% Water Evaporation Loss Rate ≤0.83%, Thermal performance:0.98～1.02Between.

7) Low noise
The cooling water of the square crossflow cooling tower drips freely down from the overflow plate box at the top of the tower, flowing over the water-filled packing sheets at the bottom of the holes, winding along the undulating surface like a snake to form a water film. The water flow is slow, and the lower part of the packing is submerged in the water in the storage tray, thus eliminating the sound of dripping without any water drop difference. This effectively reduces the noise.
