Patent ID: 7416333

Claim:
A cooling system ( 12 ) for use with an associated x-ray tube assembly ( 10 ) comprising: a heat exchanger ( 12 , 14 ) which receives cooling fluid from a housing ( 40 ) of the associated x-ray tube assembly and transfers heat between the cooling fluid and a flow of air; an axial fan ( 90 ) disposed to move the flow of air through the heat exchanger, the axial fan having fan blades with a size and shape to receive air flow along a path substantially parallel to an axis of rotation of the fan blades and to discharge air flow along a path substantially parallel to the axis of rotation of the fan blades; and an air flux director ( 110 ) positioned to intercept the flow of air from the heat exchanger and to redirect the flow of air in a direction which is generally perpendicular to an axis of rotation of the fan.
