Abstract
A cooling system for use with high-powered x-ray tubes. The cooling system includes a reservoir containing liquid coolant, in which the high-powered x-ray tube is partially immersed. In general, the liquid coolant is cooled and then circulated through the reservoir by an external cooling unit. The cooling system also includes a shield structure attached to the vacuum enclosure of the high-powered x-ray tube and disposed substantially about the aperture portion of the vacuum enclosure, thereby defining a flow passage proximate to the aperture portion. Liquid coolant supplied by the external cooling unit enters the flow passage by way of an inlet port in the shield structure. After passing through the flow passage and transferring heat out of the aperture portion, the liquid coolant is discharged through an outlet port in the shield structure and enters the reservoir to repeat the cycle.
