Abstract
A cooling system for use with high-power x-ray tubes. The cooling system includes a dielectric coolant disposed in the x-ray tube housing so as to absorb heat dissipated by the stator and other electrical components, as well as absorbing some heat from the x-ray tube itself. The cooling system also includes a coolant circuit employing a pressurized water/glycol solution as a coolant. Pressurization of the water/glycol solution is achieved by way of an accumulator which, by pressurizing the coolant to a desired level, raises its boiling point and capacity to absorb heat. A coolant pump circulates the pressurized coolant through a fluid passageway defined in an aperture of the x-ray tube and through a target cooling block disposed proximate to the x-ray tube in the x-ray tube housing, so as to position the coolant to absorb some of the heat generated at the aperture by secondary electrons, and the heat generated in the target cooling block by the target anode of the x-ray tube. The target cooling block is in contact with the dielectric fluid so that some of the heat absorbed by the dielectric coolant is transferred to the coolant flowing through the target cooling block. The heated c…
