Abstract

PURPOSE: To accomplish silencing of noise with a small pressure loss, by disposing an air-flow deflecting plate having a thru-hole in a box formed with an air inlet opening and an air outlet opening respectively in two side walls connected with each other substantially at an angle of 90 degrees, in the manner that the air-flow deflecting plate is located at the corner portion of the above two side walls and placed in contact with these two side walls.
CONSTITUTION: In a box 10 applied with sound-absorbing material 11 on its inner surface and formed with air inlet opening 12 and air outlet opening 13, an air-flow deflecting plate 14 formed with thru-hole 15 is placed at the corner portion of adjacent two side walls formed with the air inlet opening 12 and outlet opening 13. In this silencing device, air introduced from inlet opening 12 into box 10 is deflected in box 10 and discharged to the outside from outlet opening 13. Here, by the presence of air-flow deflecting plate 14, rapid expansion or contraction of air is prevented, so that air is discharged to the outside from outlet opening 13 with a small pressure loss. Further, since the corner space formed by air-flow deflecting plate 14 functions as resonance silencer, noise silencing effect can be enhanced together with the sound absorbing effect by sound-absorbing material 11.
