Sound reduction assembly for liquid-gas heat exchange type forced ventilation cooling system

摘要

A sound attenuation assembly (24;26) for a forced-draft, liquid-to-air cooling apparatus (10) having at least two rows of elongate cylindrical members (46) arranged across the air inlet (30) of the assembly (24;26) to provide a blockage to the line of sight of the air flow through the sound attenuation assembly (24;26) to provide a multiple barrier effect of frontal impact on a sound wavefront travelling through the assembly (24;26), the elongate members (46) being made of sound absorbing material, which members provide improved sound attenuation associated with the force-draft apparatus (10) while reducing back pressure losses in the air flow.
