Crossflow fans are a common type of fan, with the following main features:

1. Airflow direction: The airflow direction of a crossflow fan is perpendicular to the centerline of the fan, which means that the airflow must flow in the longitudinal direction of the fan. Compared with other types of fans (such as axial flow fans or centrifugal fans), the airflow distribution of diffuse flow fans is more uniform.

2. Planar design: Crossflow fans usually have a square or rectangular planar design. Its appearance is relatively thin and wide, and is generally used for embedded or air-cooled equipment installed in confined spaces.

3. Low noise: Crossflow fans usually have a relatively low noise level. Due to its special airflow design, the noise generated by the airflow when passing through the fan blades is relatively small.

4. Large air volume: Compared with its size, crossflow fans can provide relatively large air volume. Its design uses a large area distribution of airflow at the fan inlet and outlet, thereby increasing the air volume.

5. Compact structure: Crossflow fans usually have a compact structure and are suitable for installation in confined spaces or equipment that requires embedded design. This also makes them widely used in home appliances, central air conditioning, exhaust systems and other fields.

6. Low energy consumption: Crossflow fans generally use DC brushless motors or AC motors, which have relatively low power loss. This makes it more economical and reasonable in applications that require long-term operation or high environmental protection and energy saving requirements.

7. No need for additional guide devices: Compared with other types of fans, crossflow fans do not require additional guide devices in the design. They can directly generate the required crossflow airflow without complicated internal design.

Due to their special airflow targets and design characteristics, crossflow fans have been widely used in many fields, including home appliances, electronic product refrigeration, air conditioning units, display cabinets, electronic billboards, etc. Its high efficiency, low noise and compact characteristics make it the most ideal fan choice for many applications.
