Abstract
A centrifugal blower () for an electric-drive vehicle () having three independent air outlets () receiving air from a single impeller (). A first radial airflow () provides cooling air to an alternator () of the vehicle, a second radial airflow () provides cooling air to a control group () of the vehicle, and an axial airflow () provides cooling air to an electric drive motor () of the vehicle. The first and second radial airflows are provided through respective first and second outlets () formed at radially separated locations in a perimeter of the blower housing (). The axial airflow is provided through a generally ring-shaped third outlet () formed in a sidewall () of the housing. An air dam () provides a pressure barrier between the radial and axial airflows proximate a location where the first radial airflow is redirected to flow in a generally axial direction.
