Abstract
Das Radialgebläsegehäuse (2) einer Kraftfahrzeugklimaanlage weist eine Aufnahmeausnehmung (5) zur Aufnahme eines Radialgebläserads (3), einen Luftauslass (9) sowie eine Luftleiteinrichtung (4) zum Führen des Luftstroms von der Aufnahmeausnehmung (5) hin zum Luftauslass (9) auf. Die Luftleiteinrichtung (4) setzt zumindest auf Ihrer der Aufnahmeausnehmung (5) zugewandten Innenseite (14) die Kontur (11) der Aufnahmeausnehmung (5) zumindest im Wesentlichen fort. The radial fan housing (2) of an automotive air conditioning system has a receiving recess (5) for receiving a radial fan wheel (3), an air outlet (9) and an air guide (4) for guiding the air flow from the receiving recess (5) towards the air outlet (9). At least on its inner side (14) facing the receiving recess (5), the air guiding device (4) at least substantially continues the contour (11) of the receiving recess (5).
