  • Patent number: 7416333
    Abstract: 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.
