KG   IPC: F04D29/42 Abstract: A radial fan half-spiral housing has a pressure chamber extending in the circumferential direction about an axial intake opening (5) to a radial blow-out opening (31). The pressure chamber, as viewed in the circumferential direction, is subdivided into at least one beginning portion (7), one central portion (8), and one blow-out portion. The intake opening (5) determines a central axis of rotation for a fan wheel. An averaged half-spiral housing radius, as viewed about the axis of rotation (11), varies in the beginning portion (7), the center portion (8), and the blow-out portion (9). It reaches a maximum in the blow-out portion (9). The center portion (8) of the half-spiral housing radius is reduced in a region determining a maximum height H(δ,z) of the half-spiral housing (1) compared to a logarithmic spiral radius (rlog).
