Abstract
A heater duct can be coupled to an instrument panel of a vehicle, and comprises a base, a nozzle, and a neck. The base is sealingly coupled to the instrument panel and includes an inlet opening to receive air from a heater. The nozzle includes an outlet opening and is fluidly connected to the base. The nozzle deflects the air through the outlet opening and toward a predetermined region of a windshield. The neck extends between and is sealingly coupled to the base and nozzle. The base, nozzle, and neck cooperate to at least partially define an interior volume. The heater duct is positioned in an orthogonal coordinate system comprising an x-axis, a y-axis, and a z-axis. Air flowing from the inlet opening through the interior volume toward the outlet opening follows a path sequentially extending in substantially a negative z-direction, substantially a negative y-direction, and substantially a positive z-direction.
