Each has its own advantages and disadvantages. The number of blades of an electric fan is different, which will affect the air supply effect, noise, power consumption and price of the fan. Generally speaking, the more fan blades, the softer the air supply and the lower the noise, but it will also increase the load and cost.
1. Three-blade fan: The three-blade fan is the most classic design, has good stability, saves power and energy, and has moderate cost. However, the single blade area of a three-blade fan is larger than that of a five-blade or seven-blade fan, and the range of interaction with the air is also increased, which will produce greater noise.
2. Five-blade fan: The five-blade fan uses the principle of aircraft wings and propellers. Compared with the ordinary three-blade fan, it will increase the load and capacity, thus having a wider range of air supply. range, and the wind power adjustment can also add more gears, and the noise will also be reduced. The five-blade fan can cut the "wind" into smaller pieces, making the blown wind softer.
3. The seven-blade fan and the five-blade fan are the same. If the manufacturing cost and energy consumption are not considered, the seven-blade fan may be the most ideal fan. The seven-blade fan can cut the "wind" into finer pieces, makingThe wind blowing out is more comfortable.
