Zusammenfassung:	The utility model discloses a variable cross-section silencer which comprises a silencer base and an opening degree structure, an exhaust port is arranged in the middle of the silencer base, the silencer base is provided with a silencer base contact, the opening degree structure is arranged on the inner side of the silencer base, the opening degree structure is arranged on the exhaust port in a shielding mode, and the silencer base contact is arranged on the silencer base. The opening structure is fixedly connected with the silencer base, the opening structure is provided with a metal sheet, the metal sheet is provided with a metal contact, and the metal contact is in contact with a contact of the silencer base. According to the silencer with the variable exhaust sectional area, when the frequency of a compressor is increased, the temperature of the compressor is increased, and an opening structure is heated to be opened, the exhaust sectional area of the silencer is increased, exhaust resistance is effective
