Abstract
A fluid-cooled x-ray tube has a closed coolant circuit in which coolant circulates for the elimination of the generated heat. In order to improve the cooling capacity, micro-capsules are added to the coolant that contain a phase-change material (PCM). The micro-capsules have a size of approximately 5 μm through 20 μm in diameter.
