AI Technical Summary

Technical Problem

The noise problem of turbine fans in existing ventilators mainly relies on the properties of sponge material for noise reduction, but the effect is limited by the defects of sponge material and it is difficult to effectively reduce the noise impact.

Method used

The design adopts an integral structure of the turbine fan assembly housing, including annular radially stacked housings and multiple cavities and walls, forming a concentrated, divergent and then concentrated air path design, increasing the noise propagation path. Combined with the air inlet slot and channel design, it reduces the number of parts and assembly costs, and improves stability.

Benefits of technology

It effectively reduces turbine fan noise, improves stability and user experience, reduces assembly and material costs, and has functions such as airflow mixing, airflow stabilization, noise reduction and vibration isolation.
