The invention discloses a low-noise marine air distributor which comprises an air distributor shell, a fluid inlet, a fluid outlet and an inner flow guide baffle, the two ends of the inner flow guide baffle are each vertically provided with a micro-perforated honeycomb sound absorption structure, and each micro-perforated honeycomb sound absorption structure comprises a first baffle, a second baffle and a honeycomb tube array which are fixedly connected in sequence; the honeycomb tube array is formed by arranging a plurality of cylindrical honeycomb tubes in a transverse array mode, the first baffle is arranged on the side away from the fluid outlet, and micro-penetrating holes penetrating through the two side faces of the first baffle are formed in the positions, directly facing the center of each honeycomb tube, of the first baffle; the honeycomb tubes and the micro-penetrating holes form a Helmholtz resonant cavity for sound absorption, the shape of a gas flow channel in the air distributor is optimized by means of an oval-like air distributor shell and an arc-shaped inner flow guide baffle, generation of gas vortexes in the air distributor is weakened. According to the air distributor, aerodynamic noise and other noise transmitted to the tail end by an air conditioning system are treated at the same time, and the treatment effect is excellent.
本发明公开一种低噪音船用布风器,包括布风器外壳、流体入口、流体出口和内导流挡板,在内导流挡板的两端分别竖直设有一组微穿孔蜂窝吸声结构,其包括顺次固定相接的第一挡板、第二挡板和蜂窝管阵列,蜂窝管阵列由数个柱形的蜂窝管横向阵列排布构成,第一挡板设在远离流体出口的一侧,在第一挡板上正对每个蜂窝管中心的位置均设有贯通其两侧面的微穿孔;每个蜂窝管与微穿孔形成一个赫姆霍兹共振腔用于吸声,本申请还利用类椭圆形的布风器外壳和圆弧化的内导流挡板,优化了布风器内部气体流道的形貌,减弱了布风器内部气体涡旋的产生,该布风器兼顾处理了气动噪声和空调系统传入末端的其他噪声,处理效果优异。
