Air flux director system for x-ray tubes

摘要

A cooling system ( 12 ) for an x-ray tube assembly ( 10 ) includes a heat exchanger ( 14, 16 ) which receives cooling fluid from a housing ( 40 ) of the x-ray tube assembly and transfers the heat to a flow of air. A fan ( 90 ), such as an axial fan, directs the flow of air through the heat exchanger. The fan is positioned within a duct ( 78 ). A contoured air flux director ( 110 ) is positioned to intercept the flow of air from the duct and to redirect the flow of air in a direction which is generally perpendicular to an axis of rotation of the fan.
