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...

Components of the Cooling Fan
Sep 16 , 2021
Cooling fans have a wide range of applications, and there are many types of relative cooling fans, such as axial cooling fans, centrifugal cooling fans, and cross flow cooling fans. But its composition and structure are similar. For example, an axial fan is mainly composed of four parts: the rotor, the stator, the motor, and the outer frame. 1. Rotor part: The rotor part of the cooling fan is comp...

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 the main reasons for the noise sources of fans?
Oct 26 , 2021
Noise is a kind of noise that makes people feel noisy and boring, and its degree sometimes varies with people's mood. But continuous noise will also pollute the surroundings. The causes of noise generated by general cooling fans can be divided as follows: 1. Noise caused by blade rotation When the blade rotates, it will generate friction or impact with the air. High rpm exhaust fan, the faster the...

How to reduction the noise of fan in design?
Nov 17 , 2021
The specific noise reduction methods of the fan are as follows: (1) Enhance the aerodynamic load of the cascade and reduce the circumferential speed For the axial cooling fan, strong forward blades are used, and the multi blade impeller is beneficial to increase the aerodynamic load of the cascade. Under the same air volume and pressure, the circumferential speed on the outer circle of the impelle...

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...

Axial Fans VS. Centrifugal Fans – What’s the Difference?
Dec 21 , 2021
Applications: Axial cooling fan, which can effectively move a large volumes of air, is usually used to cool small and large spaces. They can cool electronic equipment or computer rooms. They can be used for field cooling of HVAC operations, air conditioning condensers, heat exchange units or industrial systems. Axial flow fan can also be used as exhaust fan. Centrifugal cooling fans, considering t...
