Pressure increase scroll device i.e. helical air guidance body, for e.g. air conditioning apparatus of motor car for conveying air, has circumferential shaped edge structure for making flow separation and arranged in transition region

The device (100) has a circumferential shaped edge structure for making a flow separation. The edge structure is arranged in a transition region in which a circulating- and extending partial section is passed into a diffuser. The edge structure comprises a rectangular edge angle. A fan wheel of a ra...

description The device (100) has a circumferential shaped edge structure for making a flow separation. The edge structure is arranged in a transition region in which a circulating- and extending partial section is passed into a diffuser. The edge structure comprises a rectangular edge angle. A fan wheel of a radial fan (210) is displaced into a rotating movement by utilizing a drive device during operation of a ventilation system (200). The drive device is designed as an electromotor for driving the fan wheel. Die Erfindung betrifft eine Druckerhöhungsspirale (100) für eine Lüftungsanlage (200) eines Kraftfahrzeugs, ausgebildet zum Führen der von einem Radiallüfter (210) abgegebenen Luft und zum Erhöhen des Luftdrucks. Die Druckerhöhungsspirale (100) weist eine Kantenstruktur (130) zum Hervorrufen eines Strömungsabrisses auf. Die Erfindung betrifft ferner eine Lüftungsanlage (200) mit einer solchen Druckerhöhungsspirale (100).
