Abstract
An automotive HVAC diffuser connects to a blower and a variable blower control (VBC) module having a plurality of cooling fins. An inlet receives air flow from the blower. An outlet is downstream from the inlet. An enclosed passageway is provided between the inlet and the outlet for forming a diffused air stream at the outlet. The enclosed passageway has a plurality of peripheral walls for guiding the air stream between the inlet and the outlet, including a curved outer peripheral wall corresponding to a region with a tendency for a high flow as a result of centrifugal effects. One of the peripheral walls includes a VBC receptacle formed as a depression into the peripheral wall having a substantially flat mounting surface and a first sloped side at an upstream end of the VBC receptacle to shape a portion of the diffused air stream. The flat mounting surface includes a plurality of cooling fin receiving slots arranged to receive the cooling fins, whereby the cooling fins extend into an interior of the diffused air stream.
