The invention discloses a marine air conditioner air distributor with a spiral blade, which comprises a plenum chamber body, a funnel-shaped air inlet net, a flow guide cylinder and the spiral blade, wherein the plenum chamber body is provided with an air inlet and an air outlet, the air inlet is communicated with an air inlet pipe, and the air outlet is connected with a valve plate; airflow in the plenum chamber enters a spiral flow channel through the funnel-shaped air inlet net; the flow guide cylinder is arranged at the air outlet, and the flow guide cylinder and the spiral blade form a spiral flow channel; the spiral blade wound on a blade supporting rod is of a sound absorption structure, and noise in a ventilation system can be reduced; and the inner wall of the plenum chamber body and the outer wall of the flow guide cylinder are coated with a sound absorption material. The marine air conditioner air distributor has a good noise reduction effect. Meanwhile, the air conditioner energy consumption increased due to large pressure loss is avoided, the vortex effect caused by large change of the flowing direction is relieved, and aerodynamic noise is reduced.
本发明公开了一种带螺旋叶片的船用空调布风器,包括:静压箱箱体,静压箱箱体上分别开设有进风口和出风口,进风口与进风管相连通,出风口与配流盘相连接;漏斗形进风网,静压箱内的气流经漏斗形进风网进入螺旋流道;导流圆筒,导流圆筒设置在出风口处,导流圆筒和螺旋叶片组成螺旋流道;螺旋叶片,缠绕在叶片支撑杆上的螺旋叶片为吸声结构,能降低通风系统中的噪声;静压箱箱体内壁和导流圆筒外壁贴覆吸声材料。本发明具有较好的降噪效果。同时,本发明避免了由压力损失变大而增加的空调耗能,而且减轻了因流动方向大幅度改变引起的涡流效应,降低了气动噪声。
