Broadband ventilation and sound insulation window unit structure and application thereof
The invention relates to a broadband ventilation and sound insulation window unit structure and application thereof. The broadband ventilation and sound insulation window unit structure includes an inner spiral blade (1), a hollow tube (2) and a thin-walled shell (3); the outer wall of the hollow tube (2) is fixedly connected with the inner spiral blade (1); the thin-walled shell (3) is arranged at the outer edge of the inner spiral blade (1) in a covering manner; the inner spiral blade (1) includes a fixed spiral layer (5) and horn-shaped spiral layers (4), wherein the fixed spiral layer (5)is arranged around the center of the outer wall of the hollow tube (2), and the horn-shaped spiral layers (4) are mounted on two sides of the fixed spiral layer (5); a spiral blade of the fixed spirallayer (5) is a blade with a fixed pitch; and a spiral blade of each horn-shaped spiral layer (4) is a spiral blade with a gradient change in pitch. Compared with the prior art, the broadband ventilation and sound insulation window unit structure has the advantages that the sound insulation effect is improved, the application range is wide, and the like.
本发明涉及一种宽频通风隔声窗单元结构及其应用,宽频通风隔声窗单元结构包括内部螺旋叶片(1)、空心管(2)和薄壁外壳(3),所述空心管(2)的外壁固定连接内部螺旋叶片(1),所述内部螺旋叶片(1)的外缘罩设薄壁外壳(3),所述内部螺旋叶片(1)包括设于空心管(2)的外壁中央四周的固定螺旋层(5)以及固定螺旋层(5)两侧的号筒型螺旋层(4),所述固定螺旋层(5)的螺旋叶片为固定螺距的叶片,所述号筒型螺旋层(4)的螺旋叶片为螺距梯度变化的螺旋叶片。与现有技术相比,本发明具有提高隔声效果、适用范围广等优点。
