LOW NOISE DUCT SYSTEM |
摘要 |
A system including a cabinet for intaking or discharging a gas while minimizing external duct noise and a gas duct for attachment to a housing with the gas duct having a smoothly curved passageway therein with each portion of the passageway having a cross sectional area which is sufficiently large so that the ratio of the inertia forces to viscous forces within the passageway is sufficiently small so that a laminar flow condition is maintained throughout the gas duct.
