INTAKE SILENCER FOR FUEL CELL ELECTRIC VEHICLE

摘要

PURPOSE: An intake silencer for a fuel cell electric vehicle is provided to reduce air noise and broadband noise by forming a sealed resonance space. CONSTITUTION: An intake silencer for a fuel cell electric vehicle comprises a flange(110) and a case(120). The flange comprises a tube part(111) and a board part(112). The tube part is connected to an intake pipe. The board part is coupled to the inlet of a blower(20) and is vertically extended from one end of the tube part. The case comprises a columnar part and a side part. The columnar part is separated from the outer surface of the tube part. The side part seals an opening formed between the tube part and the columnar part and forms a sealed resonance space(120a). Multiple resonance holes(111a) are formed in the tube part in a circumferential direction.
