Radial Fan

A radial fan for conveying air for a ventilator, in particular an air conditioner in a vehicle, comprising:

• an impeller that is configured to rotate about a rotational axis (RA), and a housing for the impeller,
• the housing comprising an axial intake duct, leading from outside toward the impeller,
• the housing further comprising an discharge chamber that encircles the rotational axis (RA) at a distance thereto, which radially encompasses the impeller, the discharge chamber is annular;
• the housing further comprises a discharge duct that encircles the rotational axis (RA) at a distance thereto, which is axially adjacent to the discharge chamber, the discharge duct is annular
• the intake duct is upstream of the impeller, and the discharge chamber is upstream of the discharge duct, and
• the impeller is upstream of the discharge chamber, such that when the radial fan is spinning, air is conveyed radially by the impeller into the discharge chamber and from there into the discharge duct,
• wherein the radial fan has a redirecting unit in the discharge duct through which air can flow, the redirecting unit comprises a plurality of redirecting elements distributed over the rotational axis (RA), and
• the redirecting elements are designed to redirect the air entering the discharge duct in the axial direction (AR) in relation to the rotational axis (RA).
