1. Axial-flow AC cooling fan
The characteristic of this fan is that the direction of air flow is perpendicular to the blades, and the inlet and outlet directions are the same. The blade design of the axial-flow cooling fan makes most of the air flow parallel to the axial direction. It has a high flow rate and medium wind pressure. It saves a lot of space inside electronic equipment, such as computers and servers, and is easy to install.
2. Centrifugal AC cooling fan
This cooling fan sucks air from the center of the blade through centrifugal force and throws it out along the spiral direction of the blade to form a 90-degree inlet and outlet structure. This fan is mostly used in application scenarios that require changing the direction of air flow or require strong wind pressure, such as mechanical equipment and certain specific industrial environments.
3. Cross-flow AC cooling fan
The air flow direction of this cooling fan is horizontally through the impeller, so it is also called a cross-flow fan. The axial width of the impeller is much larger than the impeller diameter, which is suitable for scenarios where heat absorption on the same horizontal plane is required inside. The cross-flow fan has a low flow rate and low wind pressure, but a large heat dissipation area, which can generate a large amount of airflow and is suitable for cooling wide surfaces, such as elevators, air conditioners and cars.
4. Mixed flow AC cooling fan
This type of cooling fan combines the characteristics of axial flow and centrifugal fans, with both high flow rate and high wind pressure. Its inlet is along the axis direction, and the outlet is along the diagonal direction of the axis and the vertical axis, which can achieve better cooling effect under high flow rate and high wind pressure.
