1. When all configurations are the same, aluminum (usually alloy) fan blades are relatively better than plastic ones because the material is harder than plastic and the air outlet is stable and strong. The advantage of plastic is its low cost. This is the most critical. If it is not a high-power fan, the advantages of plastic are higher than if it is a high-power fan, the performance advantages of aluminum; the alloy will be clearly reflected.
2. At present, the main materials of desktop fan blades include iron blades, aluminum blades and plastic blades. Their pros and cons are:
Iron blades: Don't do this. deform after long-term use and have larger air volume. However, if the quality of the blades is poor and the blade cover does notis not good, there is a hidden risk of breakage and theft, hurting people, but it consumes more electricity. ;
Aluminum blades: almost no deformation after long-term use, large air volume, lighter weight, better than iron blades. They save electricity and are relatively durable;
Plastic sheet: It is light and saves electricity, but it will deform after long-term use and appears windless. It will distort again shortly after the correction.
The cooling tower fan refers to the motor. What you want to ask is the fan blade, right? Fan blades are usually made of ABS plastic or aluminum alloy. Lixinte's large cooling towers use aluminum alloy blades, while the small ones use thickened ABS. The fan blades are generally notnot fiberglass. The tower must be made of pure fiberglass. The fiberglass cooling tower has a long service life, is corrosion resistant and is highly adaptable to outdoor work.
