Air supply system for a vehicle

摘要

The present invention relates to an air supply system for a vehicle, which includes a curved diffuser passageway (162) and a volute (163) formed on upper portion of the diffuser passageway (162) to sufficiently secure a length of the diffuser passageway, thereby enhancing a pressure conversion efficiency and reducing a size of the entire system, and which further includes a guide (150) for guiding an air flow toward an input of an impeller (170), thereby minimizing a loss occurring when air passing through a motor housing (130) flows to the inlet of the impeller, and reducing a weight of an outlet duct (160).
