The core of industrial fans is large diameter, low speed, and high air volume, which utilizes aerodynamics and motor drive to achieve large-area and strong airflow circulation.
1、 Basic working principle
After the motor is powered on, it generates torque and drives the fan blade spindle to rotate, which is the source of power. Common types: asynchronous motor, permanent magnet synchronous motor (more efficient, quieter).
When the fan blades push the air, the special wing shaped fan blades rotate, compressing the air from the front and accelerating downwards/forwards, forming a directional airflow; A negative pressure zone is formed on the back to supplement the surrounding air and achieve continuous air supply.
Forming a three-dimensional wind field with large-diameter fans is not just about "blowing directly", but also about promoting overall air flow and convective ventilation:
Accelerate indoor and outdoor air exchange
Blow away heat, moisture, dust, and odors
Form a uniform wind field covering a large area
2、 Core Physics Principles
Bernoulli's principle: The curved surface of the fan blade creates a pressure difference due to the difference in air flow velocity, achieving air propulsion.
Momentum transfer: The fan blades convert rotational kinetic energy into axial kinetic energy of the air, forming strong winds.
Large area coverage: Low speed+large diameter, using high air volume instead of "high wind speed direct blowing", providing a more comfortable feeling and wider coverage.
3、 Summary in one simple sentence
The motor drives the special wing shaped fan blades to rotate, promoting the directional flow of air, forming a large area, strong convection ventilation and cooling wind field, achieving ventilation, cooling, dehumidification, deodorization, and dust removal.
