[0005] Furthermore, the cross-section of the protrusion on the noise reduction plate is in the shape of an arc.

[0006] Furthermore, the cross-sectional edge of the protrusion is wavy.

[0007] Furthermore, the first sound-absorbing cotton layer is a sponge layer having a plurality of sound-absorbing cavities distributed in a rectangular array.

[0008] Furthermore, the above-mentioned silencer cavity has a cavity, the cavity corresponds to the protrusion one by one and a cavity is formed between the two, and one end of the cavity has a sound transmission hole, which extends to the thermal insulation cotton layer.

[0009] Furthermore, the above-mentioned thermal insulation cotton layer is pearl cotton, and an aluminum foil layer is provided on one side of the pearl cotton.

[0010] Furthermore, the second sound-absorbing cotton layer is aluminum silicate cotton.
