摘要
根据离心式风机的噪声特点以及微穿孔板消声结构的吸声理论，结合风机气流对噪声影响的机理，提出了用微穿孔板消声结构组成的能改善风机进气口气体流动情况的盘式微穿孔板消声器结构，并进行了试验验证。
ccording to the noise characters of centrifugal fan and sound absorption theory of mini-hole plate's noise elimination Structure, with combining the mechanism of fan airflow affecting noise, a kind of noise elimination structure of mini-hole plate was put forward to improve the gas flowing situation of fan gas-entering's enterance and tested by experiments.
