A SILENCER TUBE OF AUTOMOBILE MUFFLER

摘要

PURPOSE: A silencer tube of an air conditioner for a vehicle is provided to effectively damp the frequencies of vibration and noise caused when refrigerant is discharged by repetitively removing the pressure differences of the refrigerant. CONSTITUTION: A silencer tube of an air conditioner for a vehicle comprises a refrigerant transfer pipeline, a silencer tube(120), stepped pulley parts(130), a spiral protrusion part(140), and space parts The silencer tube having a smaller diameter than the inner diameter of the refrigerant transfer pipeline is embedded in the refrigerant transfer pipeline between a compressor and a heat exchanger. The stepped pulley parts are protruded from both ends of the silencer tube. One side of the stepped pulley parts is opened to form a refrigerant outlet(131). A spiral protrusion part is formed on the exterior of the silencer tube. Space parts are formed between threaded portions of the spiral protrusion parts.
