A Brief Description of Axial Fans
Jul 07 , 2021
Axial fans date back to the horizontally configured windmills of Europe in the Middle Ages. The first electrically powered fans, introduced in the 1880s, were axial fans. Axial flow fans are named for the direction of the airflow they create. When an axial fan works, the blades push the air to flow in the same direction as the axis, so it is called the axial fan. An axial fan, as the name ind...

Cooling Fan - What are the relevant parameters
Aug 25 , 2021
Airflow The airflow of cooling fan refers to the total airflow of air discharged or absorbed by the cooling fan per minute. If calculated in cubic meters, it's the CMM. The airflow unit often used by cooling fans is CFM (about 0.028 m3 / min). Large air volume fan, airflow is the most important index to measure the cooling capacity of cooling fans. Obviously, the larger the airflow, the highe...

Why the blades of an axial fan are odd and not even？
Sep 08 , 2021
First of all, many people find that the structure of the cooling axial fan blades is composed of odd numbers such as 3, 5, 7, 9 and 11. However, many consumers are not very familiar with it, and are curious, whether this is just a design coincidence or another mystery Where? As we all know, the actual heat dissipation effect of a cooling fan largely depends on the design of the blade pitch and the...

Characteristics and application fields of cross flow fan
Dec 02 , 2022
The cross flow cooling fan impeller is multi blade type. The shape is long cylindrical, with front multi wing blades. When the impeller rotates, the air flow enters the blade column from where the impeller is opened. The volute is discharged from the blade column on the other side through the impeller to form the working air flow. This is a brief introduction and working principle of the cross flo...
