摘要： A centrifugal fan with a pot-like impeller and with a housing, having a first circumferential wall region with an arc-like curvature which extends directly along the impeller. The housing includes in a direction of rotation of the impeller a second circumferential region with a radial distance from the impeller increasing spirally up to an outlet region. The housing includes in an opposite direction a third circumferential wall region extending to the outlet region, having an S-curvature and including a sub-region curved in the same direction as the first circumferential wall region forming a flow baffle element. Two side walls cover the axial end faces of the impeller wherein one of the side walls extends into the pot-like impeller and divides its interior into a first suction chamber having an intake and a second suction chamber. The outlet region expands in cross-section in the outlet flow direction.

摘要： Proposed is a centrifugal fan with a pot-like impeller (10) and with a housing (11) accommodating the impeller (10), the circumferential wall (18) of which, starting from a first circumferential wall region (19) with an arc-like curvature which extends directly along the impeller (10), comprises on the one hand in the direction of rotation of the impeller (10) a second circumferential region (20) with a radial distance from the impeller (10) increasing spirally up to an outlet region (21) and on the other hand against the direction of rotation of the impeller (10) a third circumferential wall region (22) likewise extending to the outlet region (21). Two side walls (25, 26) cover the axial end faces of the impeller (10), wherein a partition (28) on one of the side walls extends into the pot-shaped impeller (10) and divides its interior into a first (V1) and a second (V2) suction chamber, an intake (29) being assigned to the first suction chamber (V1). The third circumferential region (22), starting from the first circumferential region (19), has an S-curvature towards the outlet region (21), its sub-region (24) curved in the same direction as the first circumferential wall region (19) forming a flow baffle element for the air flow returned to the second suction chamber (V2). The outlet region (21) expands in cross-section in the manner of a diffuser in the outlet flow direction. This design results in a centrifugal fan with increased efficiency and increased fan power combined with a lower volume.
