  • HVAC BLOWER WITH NOISE SUPPRESSION FEATURES
    Publication number: 20140251721
    Abstract: A blower for an HVAC system of a motor vehicle. A fan is supplied with airflow by a duct having a bend adjacent to the fan that causes a low-pressure region at a face of the fan. A baffle is located immediately adjacent to the fan face and collocated with at least a portion of the low-pressure region to impede airflow through the face of the fan at that location. The baffle acts to reduce unwanted low frequency noise and improves the mechanical efficiency of the fan. The baffle covers a circular segment of the fan face and may have sound-suppressing features, such as ridges formed on at least one surfaces.
