Furthermore, a plurality of the noise elimination body is the matrix equidistance and sets up in the installation casing, the matrix distribution makes the noise elimination body sound absorption effect more even, and the while is convenient for process and installation, has guaranteed beautifully.

Further, the noise reduction cotton comprises one or more of glass cotton or glass fiber cotton, and the glass cotton or the glass fiber cotton has the advantages of high temperature resistance, high hydrophobicity, sound absorption and noise reduction, so that the sound absorption effect is further improved.

Further, the installation shell comprises but is not limited to a metal frame, a civil engineering wall or a pipeline, and in practical application, the installation support can be fixed at the positions of the metal frame, the civil engineering wall or the pipeline and the like according to requirements, so that the application range is wide.

Further, the mounting shell can be in a shape including but not limited to a rectangle, a circle or a polygon, and the mounting bracket can be trimmed along the mounting position as required to meet the mounting requirements, so that the noise damper is fixed and can be adapted to mounting environments with various shapes.

Furthermore, a reinforcing member is arranged between the mounting brackets and is vertically connected with each mounting bracket, so that the stability of the mounting brackets is improved, and the noise elimination body is more stable.

Compared with the prior art, the invention has the beneficial effects that:

the five-petal flower-shaped silencing framework is arranged, so that the perimeter of the silencing body is greatly increased, and the silencing effect is improved; meanwhile, the silencing framework is made of a microporous plate, so that the sound absorption efficiency is improved; in addition, the cross-sectional area of the flow guide cover on the silencing framework is gradually reduced along the position direction of the connecting and mounting bracket, and the wind resistance is greatly reduced by matching with the silencing bodies distributed in a matrix manner. The invention not only increases the perimeter of the noise elimination body, improves the noise elimination effect, ensures the sound absorption efficiency, but also greatly reduces the wind resistance and improves the attractiveness of the equipment.
