The invention provides a low-flow-noise marine ventilation terminal. The low-flow-noise marine ventilation terminal comprises a box body, a porous flow guide silencing partition plate, an air inlet and an air outlet. The box body is connected with the air inlet and the air outlet, and an airflow flows into the box body from the air inlet and then flows out of the box body from the air outlet. Theporous flow guide silencing partition plate is arranged in the box body and divides a space in the box body into an air inlet cavity and an air outlet cavity, the air inlet cavity is connected with the air inlet, the air outlet cavity is connected with the air outlet, the porous flow guide silencing partition plate is made of sound absorption materials and provided with a plurality of through holes, and the airflow flows into the air outlet cavity from the air inlet cavity through the through holes.
本公开提供了一种低流噪船用布风器,其包括箱体、多孔导流消音隔板、进风口和出风口。箱体分别与进风口和出风口连接,气流由进风口流入箱体,再由出风口流出箱体。多孔导流消音隔板设置在箱体内,将箱体内的空间分隔为进气腔室和出气腔室,进气腔室与进风口连通,出气腔室与出风口连通,多孔导流消音隔板由吸声材料制备,设置有多个通孔,气流经由通孔从进气腔室流入出气腔室。
