The cooling fan is an essential heat dissipation tool for various heat-generating equipment, and the size of the fan can be divided into 8mm-280mm, etc., the voltage is 5V, 12V, 24V, 48V, 110V, 220V, 380V, etc., some manufacturers can also according to customers Custom fan. What is the difference between these fans? Quickly understand the four types of cooling fans with Suzhou Santian Precision Mould Co., Ltd.!
Cooling fans are divided into four types according to different flow directions of fans: axial fans, mixed flow fans, centrifugal fans, and cross-flow fans.
1. Axial fan
The blades of the axial fan make the air flow in the same direction as the shaft. When the axial fan is working, most of the air flow is along the axis, and in the free air state where the inlet air flow is 0 static pressure, the power consumption of the axial fan is the lowest.
The axial fan can be installed in the cabinet of the electrical and electronic equipment, or it can be integrated with the motor. Because the axial fan has a compact structure, it can save a lot of space and is easy to install.
The axial fan can meet the heat dissipation requirements of high flow rate, medium pressure, and common environment.
2. Mixed flow fan
Mixed-flow fans are also called diagonal fans. Its appearance is the same as axial fans, but the inlet of the fan is along the axis and the outlet is diagonal to the vertical axis.
The mixed flow fan can meet the heat dissipation requirements of high flow rate, high wind pressure and ordinary environment.
3. Centrifugal fan
A centrifugal fan refers to a fan whose blades make air flow in a direction perpendicular to the axis, and the suction is along the axis, but the exhaust is perpendicular to the axis.
Centrifugal fans can be selected when it is necessary to rotate the gas by 90° to discharge it, or when a greater air pressure is required than an axial fan. Most centrifugal fans are small centrifugal fans, and the fans are multi-wing type, which is the most widely used in mechanical equipment.
The centrifugal fan can meet the heat dissipation environment that changes the wind direction and high air pressure, and has requirements on the current flow rate.
4. Cross-flow fan
A cross-flow fan is also called a cross-flow fan, which can cause large-scale airflow when working.
The cross-flow fan usually needs to work with a long cylindrical fan impeller. In order to reduce the noise caused by high-speed operation, the matching fan impeller needs to choose a large diameter, so the cross-flow fan is often used in elevators, air conditioners, automobiles, etc. It is only used to cool the wide surface of the equipment, and it is rarely installed inside the machine.
The cross-flow fan can meet the heat dissipation requirements of low flow rate, low wind pressure and large heat dissipation area.
