There are two main ways to create fog for spray fans

At present, the spray fans on the market include: atomizing fan, water-cooling fan, cooling fan, atomizing cooling fan, cooling fan and many other different names; there are two mainstream methods of fog generation or fog generation of the water mist fan : One is a high-pressure nozzle spray fan, the other is a centrifugal spray fan.

A: The high-pressure nozzle spray fan water has a pressure of tens of kilograms under the action of the high-pressure water pump. The high-pressure nozzle produces micro-mist. The diameter of the droplet is less than 10 microns, so the evaporation surface area is greatly increased. The micro-mist is blown out by the powerful fan. , Which greatly increases the wind speed on the liquid surface and accelerates the diffusion of gas molecules, so the evaporation of water is greatly increased. The water absorbs heat during the evaporation process, reduces the temperature, and can increase the relative humidity of the air, reduce dust, and purify the air; this This kind of fan uses nozzles to generate micro mist through high pressure, so it is called high pressure nozzle spray fan.
B: The centrifugal spray fan water is under the action of the high-speed rotating disk. Due to the friction between the water and the rotating disk, the water makes a circular motion with increasing speed, and the water will follow the outermost edge of the disk. When the tangential direction goes out quickly, the high-speed water collides with solid obstacles, which will produce extremely tiny droplets, which greatly increases the evaporation surface area; the airflow blown out by the powerful fan greatly increases the wind speed on the liquid surface and accelerates Due to the diffusion of gas molecules, the evaporation of water is greatly increased. The water absorbs heat during the evaporation process and reduces the temperature. At the same time, it can increase the relative humidity of the air, reduce dust, and purify the air; this spray fan uses the principle of centrifugal movement of objects, Therefore, it is called a centrifugal spray fan.
