Abstract: An x-ray tube cooling system including a heat sink at least partially disposed within an evacuated housing of the x-ray tube and having a cooling block partially received within the bearing housing so as to absorb heat transmitted to the bearing assembly and bearing housing. Extended surfaces, are disposed in a coolant chamber cooperatively defined by the cooling block and a shell within which the cooling block is partially received. The shell defines a coolant chamber entrance and coolant chamber exit in fluid communication with the coolant chamber. The coolant chamber entrance and exit communicate with corresponding coolant inlet and outlet passageways, respectively, cooperatively defined by a pair of insulators which retain the heat sink in a predetermined orientation within an evacuated envelope of an x-ray device. A circulating coolant contacts the extended surfaces and thereby removes heat from various structures of the x-ray device.

Abstract: An x-ray tube apparatus includes a housing defining a chamber and an x-ray tube mounted therein. The x-ray tube includes an envelope defining an evacuated void in which an anode assembly is rotatably mounted to a bearing assembly. The anode assembly interacts with a cathode assembly for the production of x-rays. The bearing assembly includes a cooling channel that is defined within the bearing assembly to direct cooling fluid, such as oil, across an inner surface of the bearing housing. A flow director is located in a fluid input port in the housing and has a fluid input aperture for connecting the flow director to the heat removal system. A cavity is defined by the housing of the flow director and two fluid output apertures are in fluid communication with each other and the fluid input opening. One of the fluid output apertures supplies cooling fluid to the cooling channel in the bearing assembly and the other fluid output aperture supplies cooling fluid to the chamber in the housing. The fluid director provides a desired predetermined portion of supplied fluid flow of the cooling fluid to the cooling channel and/or chamber.

Abstract: A high energy x-ray tube includes an evacuated chamber (12) containing a rotor (34) which rotates an anode (10) through a stream of electrons (A) in order to generate an x-ray beam (B). The rotor includes a bearing assembly (C) having a hollow bearing shaft (52) centrally aligned with a longitudinal axis (Z) of the rotor. The bearing shaft includes an interior annular wall (54) having an inner surface which defines a central bore (58). The bearing shaft has an outer surface (60), which with an inner surface of the bearing shaft, defines an annular chamber (62). An opening (64) is provided at the forward end of the annular wall to provide access from the central bore to the annular chamber. During exhaust processing, baking cycles, and normal operation of the x-ray tube, a pump (104) forces a cooling medium through the central bore, through the opening of the annular wall, and into the annular chamber. The cooling medium exits through channels (66). While in the annular chamber, the cooling medium cools a plurality of forward and rearward lubricated bearings (48F, 48R) located adjacent an outer surface of the hollow bearing shaft.
