Abstract
The present invention provides a centrifugal fan comprising: an impeller; and a scroll housing covering the impeller and having an intake and an outlet formed thereon. The scroll housing comprises a base plate, a scroll wall and a discharge wall. The scroll wall is connected to the base plate and is formed to have a scroll-shape formed from a cut-off part thereof. The discharge wall is extended from the scroll wall. A flow path expansion part convexly protrudes from the base plate in the external direction of the scroll housing, and the flow path expansion part have a cross-section of a flow path, which is gradually expanded in an air flow direction. Expansion flow paths are formed in two directions of a second direction where the scroll wall is expanded and a direction where the flow path expansion part protrudes such that superior capability to recover a static pressure of discharge air is secured, and ventilation performance can be improved. The flow path expansion part protrudes from the base plate, thereby increasing the usability of space adjacent to the flow path expansion part.
