According to one embodiment, an X-ray tube assembly includes a cathode, an anode target, a joint including an inflow part into which a coolant flows, a first cylindrical pipe to which the joint is connected at one end, and the anode target is joined at an outer bottom part of the other end, a second cylindrical pipe whose first end part is fitted into the inflow part, and whose second end part is arranged to eject the coolant toward the bottom part of the first cylindrical pipe, the second cylindrical pipe being placed inside the first cylindrical pipe and an elastic member provided between the first end part and the first cylindrical pipe.

A cooling device for x-ray tubes in x-ray generators, comprising a housing with a central receiving device for receiving an x-ray tube with an inlet opening for supplying a gaseous coolant, an outlet opening for discharging the gaseous coolant, and a gas-conducting channel which extends between the inlet opening and the outlet opening. The gas-conducting channel is designed to conduct the gaseous coolant directly by the high-voltage x-ray tube housing during operation. The gas-conducting channel additionally extends in a helical manner about the x-ray tubes such that the electric potential applied to the x-ray tubes drops to zero potential along the gas-conducting channel.

An x-ray tube casing is provided which includes a central frame having internal passages to supply a cooling fluid directly to the casing without the need for an external dedicated heat exchanger. The cooling fluid flowing through the passages in the easing can thermally contact the dielectric coolant within the casing to cool the tube coolant during operation of the x-ray tube. The casing is formed in an additive manufacturing process to allow for tight tolerances with regard to the structure for the casing and the internal passages to reduce the size and weight of the casing. The casing can additionally be formed from a metal matrix including a metal with high x-ray attenuation and a filler metal. The metal matrix eliminates the need for a separate x-ray attenuation layer within the casing, further reducing the size, number of parts and assembly complexity of the casing.
