Abstract: A rotating anode for x-ray generation uses a heat pipe principle with a heat pipe coolant located in a sealed chamber of a rotating portion of the anode. The rotating portion is positioned relative to a second portion so that relative rotation occurs between the two portions and so that a fluid path exists between the two portions through which an external cooling fluid may flow. The relative motion between the two portions provides a turbulent flow to the cooling fluid. The anode may also include cooling fins that extend into the sealed chamber. The sealed chamber may be under vacuum, and may be sealed by o-rings or by brazing. A closable fill port may be provided via which heat pipe coolant may be added. A balancing mass may be used to balance the anode in two dimensions.

Abstract: A coolant passage is formed inside the rotary shaft while an air passage is formed inside the casing. A mechanical seal is arranged between the coolant passage and the air passage. Leakage cooling water, which has leaked in the form of vapor from the mechanical seal, is relegated radially outwardly along with air by the action of a rotary vane, which is disposed in the air passage, and finally flows out of an air outlet. A coolant sensor may be provided to early detect the leakage water.

Abstract: A rotating anode for an x-ray tube has an anode body composed of composite fiber material, mounted in a bearing system, the anode body having a target surface with a focal ring and including fibers with particularly high heat conductivity in the longitudinal direction. An axis-proximal cooling system is associated with the anode body. The majority of all fibers with high heat conductivity in the longitudinal direction terminate bluntly both at the focal ring and at the cooling system, such that their abutting faces respectively are in direct, heat-conducting contact both with the focal ring and with the cooling system.
