Blower - The Working Principle of Centrifugal Fan
Jul 15 , 2021
Centrifugal fan is a machine that relies on input mechanical energy to increase gas pressure and discharge gas. It is a driven fluid machine. Centrifugal exhaust fans can be widely used for cooling and ventilation in air conditioning equipment, household appliances and medical equipment. The working principle of a centrifugal blower fan is basically the same as that of a turbo compressor, except t...

Blower - The Characteristics of Centrifugal Fans
Aug 19 , 2021
The centrifugal fan is mainly composed of an impeller and a casing, and the impeller of a small centrifugal fan is directly mounted on the motor. Centrifugal fans are generally single-sided air intake and use single-stage impellers. The impeller is the main component of the centrifugal fan. Its geometry, size, number of blades and manufacturing accuracy have a great influence on performance. The i...

What is the difference between centrifugal, axial and cross flow fan blades?
Sep 26 , 2021
1. Centrifugal fan Centrifugal blower fan is based on the principle of converting kinetic energy into potential energy, using a high speed rotating impeller to accelerate the gas, then decelerate and change the flow direction, so that the kinetic energy is converted into potential energy (pressure). In a single stage centrifugal fan, the gas enters the impeller from the axial direction, changes to...

What are DC Centrifugal Fans?
Dec 21 , 2021
Centrifugal fans are sometimes called radial fans or centrifugal blower fans. They have a motor-driven hub which contains an impeller that discharges air into the housing and then directed to an outlet. The centrifugal fan exhausts air at an angle of 90 degrees (perpendicular to the air inlet). Centrifugal type fans mainly pressurize the air in the blower housing. Compared with axial fans, they pr...

Use of axial fans and blowers
Dec 28 , 2021
In the cooling fan, the DC fan provides variable flow and the AC fan provides constant flow. In addition to AC power supply and DC power supply, cooling fans are usually classified according to the way air enters and exits the fan. In an axial fan, air enters and exits in the same plane. If the airflow leaves in different planes, this is called centrifugal design or blower. Natural convection cool...

Cooling Fan - AC Shaded Pole Induction Motor
Jan 05 , 2022
In addition to the DC brushless motor, there is another type of shaded pole induction motor in the exhaust cooling fan. As the name suggests, Induction motors is because electromagnets in the stator induce magnetism in the rotor. They induce magnetism in the rotor because, unlike the rotor in a brushless DC motor, the rotor in an induction motor contains no magnets. A separate small winding is use...

Where is the cooling fan used?
Feb 23 , 2022
Cooling fans, as the name suggests, are used for ventilation and heat dissipation. It is widely used in various industries and fields, because in many electronic equipment and machinery, if there is no cooling device installed in the equipment, the working temperature may be too high, which may cause the performance of the equipment to decline, or even be damaged. For normal and efficient operatio...
