Ventilation and noise reduction shutter structure
The ventilation and noise reduction shutter structure comprises a shutter outer frame and blade units, the shutter structure comprises at least one layer of blade units, each blade unit is composed of a plurality of blades arranged linearly, each blade comprises a straight section and an arc-shaped section, one end of each straight section is fixedly connected with one end of the corresponding arc-shaped section, and the other end of each straight section is fixedly connected with the corresponding arc-shaped section. The straight sections of the multiple blades in one blade unit are parallel to one another, the circle centers of the multiple arc sections are located on the same straight line, the radian of the arc sections is 180-190 degrees, the side, close to the blades, of the arc sections is the airflow inlet direction, and the side, close to the blades, of the straight sections is the airflow outlet direction. The effect of one-way conduction of the Tesla one-way valve on airflow is achieved. According to the invention, a Tesla one-way valve type structure with a one-way conduction effect on airflow is adopted, so that wind resistance in the air inlet direction is reduced, structural noise elimination in the direction opposite to the air inlet direction is realized, the noise reduction effect is improved, and the dual effects of ventilation and noise reduction are considered.
本发明公开了一种通风降噪百叶结构，包括百叶外框和叶片单元，百叶结构包括至少一层叶片单元，叶片单元由多个呈线性排列的叶片组成，叶片包括一直形段和一弧形段，直形段的一端固定连接弧形段的一端，且直形段相切于弧形段的开口侧，一个叶片单元中多个叶片的直形段相互平行、多个弧形段的圆心位于一条直线上，弧形段的弧度为180°～190°，靠近叶片的弧形段侧为气流进气方向，靠近叶片的直形段侧为气流出气方向，形成对气流具有特斯拉单向阀单向导通的效应。本发明采用对于气流具有单向导通效果的特斯拉单向阀式结构，实现了进风方向上减小风阻、进气反方向上的结构消声，提高了降噪效果，从而兼顾了通风与降噪的双重效果。
