Working principle: A crossflow fan generates airflow through a transverse channel. Usually, a crossflow fan consists of a rotating cylinder or rectangular body with multiple curved blades installed in it. When the motor drives the fan to rotate, the airflow is pushed into the channel by the action of the blades and flows in the transverse direction of the channel. Finally, the airflow is released through the outlet.

Application field: Crossflow fans are widely used in many fields. Some of the newly opened applications include electronic equipment parts, such as TVs, computers, audio systems, etc.; air conditioning and ventilation systems, including offices, commercial buildings and residences; household appliances, such as ovens, microwave ovens, washing machines, etc.; and other equipment that requires air circulation and heat dissipation.

Advantages:

1) Compact size and flexible installation: Crossflow fans are usually smaller in size than other types of fans, so they are easier to install and integrate in applications with limited space.

2) Uniform airflow distribution: The design of crossflow fans allows the airflow to be evenly distributed in the channel, ensuring uniform air volume and heat dissipation throughout the channel.

3) Lower noise level: Due to the uniform distribution of airflow and less mechanical vibration, crossflow fans usually produce lower noise levels and are suitable for applications that require a low noise environment.

4) Multi-directional airflow output: Crossflow fans usually have multiple outlets, which can output airflow in different directions and cover a wider area.

Limitations:

1) Lower pressure generation capacity: Compared with centrifugal fans, crossflow fans have lower pressure generation capacity. Therefore, in applications that require high pressure, crossflow fans may not meet the requirements.

2) Smaller air volume: Compared with centrifugal fans, crossflow fans usually have smaller air volumes. . This means that in scenarios that require a large amount of airflow, other types of fans may need to be considered.

In general, crossflow fans have obvious advantages in some specific application scenarios, such as equipment with limited space, systems that require uniform airflow distribution, and environments with high noise requirements. However, when choosing the type of fan, it is still necessary to comprehensively consider the specific application requirements and performance indicators.
