The right side of the sound insulation cotton frame 11 is connected to a sound insulation cotton board 12 through a connecting component 13. An industrial motor 2 is embedded and installed inside the sound insulation cotton frame 11. The left side of the sound insulation cotton frame 11 is connected to an air outlet pipe 14. The left side of the sound insulation cotton board 12 is connected to a rubber ring 16, and the rubber ring 16 is in contact with the inner wall of the sound insulation cotton frame 11. Two shunt pipes 15 are connected to the right side of the sound insulation cotton board 12, and the end of the shunt pipe 15 is connected to a pipe group 3.

[0023] The bottom of the sound-absorbing cotton frame 11 is provided with heat dissipation grooves, and the heat dissipation grooves are arranged at equal distances at the bottom of the sound-absorbing cotton frame 11 .

[0024] The connecting component 13 includes a plate sleeve 131 connected to the side of the sound-absorbing cotton frame 11. Two plug plates 134 are symmetrically connected to the two sides of the sound-absorbing cotton plate 12, and the plug plates 134 are embedded in the plate sleeve 131 through slots.

[0025] A latch pin 132 is inserted through a through hole at the bottom of the plate sleeve 131 , a return spring 133 is sleeved on the outer side of the latch pin 132 , and a plug hole matching the latch pin 132 is formed on the surface of the plug plate 134 .

[0029] Through the heat dissipation groove design at the bottom of the silencer cotton frame 11, the heat generated by the industrial motor 2 can be easily exchanged with the ground surface, reducing the heat resistance effect brought by the silencer cotton frame 11 when it is installed. When the silencer cotton frame 11 is docked with the silencer cotton board 12, the plug plate 134 can be inserted into the plate sleeve 131 to facilitate the positioning of the installation of the silencer cotton board 12.
