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...

Cooling fan - Speed control systems
Dec 30 , 2021
Brushless DC (BLDC) fans are the most common type used to cool electronic equipment. Many cooling fans now have additional functions which provide greater control the fan speed and operation, thus improving the system performance. Having a fan run constantly even when maximum cooling is not required, does not result in an efficient system and can reduce the service life of a fan. If the average sp...

Cooling Fan - Brushless DC Motor
Jan 05 , 2022
Motors that power ventilation cooling fans are usually divided into brushless motors or induction motors. Brushless motors are sometimes called electronically commutated motors. Commutation refers to the act of switching the electrical connection from one motor winding to the next one. Motor windings in the DC cooling fan motor is generally located in the stator or stationary portion of the ...

If the positive and negative poles are reversed, will the cooling fan burn out?
Jan 18 , 2022
DC cooling fan has two positive and negative power lines. When installing the cooling fan, if the positive and negative lines are connected reversely by wrong operation, will the cooling fan burn out? Whether the axial cooling fan is burnt out or not is mainly related to the IC Design of the cooling fan. In general, the drive IC with double wire winding method has internal protection design. If th...

How to choose the cabinet cooling fan?
Jan 26 , 2022
1. When purchasing cabinet cooling fans, first confirm the size of the cabinet, select the appropriate fan model and appearance for installation, and then determine the parameters such as voltage, airflow, speed, current, noise and other parameters. 2. Cooling fan voltage, which can be divided into DC voltage 5v, 12v, 24v and 48V; AC voltage 110V, 220v, 380v. If the wrong voltage is connected, the...

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...

Why the speed of DC cooling fan slows down?
Mar 26 , 2022
Why the speed of DC cooling fan slows down? The speed of the cooling fan is determined by voltage, fan blade angle, diameter, number of fan blades, bearings, etc. So what is the reason why the cooling fan slows down? The speed of the cooling fan is mainly determined by the structure and components of the fan itself, the bearing friction and the wind resistance of the inclination angle of the fan b...
