Abstract (en)
[origin: US2002067988A1] A ventilator housing of a ventilator has a flow passage having an intake opening and an outlet opening. Outflow contouring devices are arranged about the outlet opening and are configured to at least reduce a vortex formation within a shearing layer that is generated during operation of the ventilator so as to surround an actual airflow of the ventilator and that is located between the airflow and surrounding air. The outflow contouring devices enlarge the proportion of uninterrupted air flow relative to the entire flow cross-section of the flow passage.
