How does the dual-impedance structure of the Silent Pipeline Mixed Flow Fan improve air flow and reduce noise?

Design principle of the dual-impedance structure
The dual-impedance structure, that is, the fan is equipped with two impedances, this design optimizes air flow by configuring the impedances in parallel. Each impedance has its own independent air flow path, and the overall ventilation effect is improved through synergy. The core advantage of this structure is that it can increase the air flow and static pressure of the Silent Pipeline Mixed Flow Fan while maintaining relatively low operating noise.

Mechanisms for improving air flow
Increase air volume output: The dual-impedance structure can significantly increase the air volume output of the Silent Pipeline Mixed Flow Fan. The two impedances work in parallel, allowing the fan to move more air per unit time. This design effectively improves the ventilation capacity of the fan, especially in application scenarios that require high air volume. Through the synergy of the dual impedances, the fan can achieve higher airflow efficiency, thereby improving the overall air flow performance.

Optimize airflow path: The dual impedance structure optimizes the airflow path. The two impellers make the airflow more uniform and smooth when passing through the Silent Pipeline Mixed Flow Fan, reducing the turbulence of the airflow.

Improve static pressure performance: Due to the dual impeller design, the Silent Pipeline Mixed Flow Fan is able to provide higher static pressure. This means that the fan can maintain a stable air flow even in long ducts or complex ventilation systems.

Mechanisms for reducing noise
Reduce airflow turbulence: The dual impeller structure effectively reduces airflow turbulence by optimizing the airflow path. Airflow turbulence is one of the main causes of noise in Silent Pipeline Mixed Flow Fans. The dual impeller design makes the airflow more stable when passing through the fan through the synergy of the two impellers, reducing the noise caused by airflow turbulence.

Reduce vibration and noise transmission: The dual impeller structure helps to balance the operating vibration of the Silent Pipeline Mixed Flow Fan. Each impeller shares a part of the airflow load, thereby reducing the overall vibration level of the fan. The reduction in vibration not only directly affects the noise level of the fan, but also reduces the noise transmitted to the fan housing and the surrounding environment. The cold-rolled sheet metal housing further helps to suppress vibration and noise transmission, improving the quiet performance.

Improve wind rotor efficiency: The dual-rotor design enables each wind rotor to work at its optimal operating state, thereby improving the overall wind rotor efficiency. Efficient wind rotor operation not only improves the stability of the airflow, but also reduces the noise caused by low wind rotor efficiency.
