Abstract

The application relates to a noise reduction device which comprises a first base and a sound insulation cover. The sound-proof housing is arranged on the first base. The sound-proof housing includes a first sound-proof panel and a second sound-proof panel. The first sound insulation plate and the second sound insulation plate are rotatably arranged on the first base, so that the sound insulation cover has an open state and a closed state. Under the closed state, the first acoustic baffle contacts with the second acoustic baffle and encloses to form an acoustic insulation space, so that the first acoustic baffle and the second acoustic baffle are closed and enclose outside the part to be noise reduced, and the first acoustic baffle and the second acoustic baffle can isolate noise generated by the part to be noise reduced, thereby achieving the purpose of noise reduction. Under the open state, the first acoustic celotex board separates with the second acoustic celotex board, realizes the opening of acoustic celotex board, treats like this that the heat that the part produced of making an uproar can discharge fast to reach radiating purpose.
