AI Technical Summary
Existing exhaust ducts used in chip processing generate noise during ventilation due to turbulence, affecting the quietness of operation.
The design incorporates sound-absorbing panels and sheets, combined with centrifugal glass wool and a guiding device. The sound-absorbing panels and sheets absorb sound through their perforated and cavity structures, while the guiding device evenly disperses the airflow, reducing noise inside the exhaust duct.
It effectively reduces the noise inside the exhaust pipe, improves the quietness of use, and meets the usage requirements.
