What is the relationship between starting voltage and cooling fan?
Dec 14 , 2021
With the increasing use of cooling fans, many people are interested in the details of cooling fans. Some people will ask whether the low voltage will affect the cooling fans. Low voltage has no effect on the fan, it will only make the fan rotate at low speed, which can prolong the service life of the fan, but low voltage for a long time may damage the motor. Voltage includes starting voltage and o...

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 - 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 ...

How to design dust-proof cooling fans?
Jan 11 , 2022
The characteristics of the cooling fan itself are different from other products. Brushless cooling fan actively stirs the air and accelerates the airflow, so it also sucks in dust. There are two main aspects of inhaling dust. One is sucked into the bearing and the other is sucked into the rotor and stator. Inhalation of dust more or less affects the cooling fan, causing the fan to slow down and ev...

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...
