摘要： An x-ray tube apparatus includes a housing (12) defining a chamber and an x-ray tube mounted therein. The x-ray tube includes an envelope (16) defining an evacuated void in which an anode assembly (20) is rotatably mounted to a bearing assembly (44). The anode assembly interacts with a cathode assembly (22) for the production of x-rays. The bearing assembly includes a cooling channel (85) that is defined within the bearing assembly to direct cooling fluid, such as oil, across an inner surface (47) of the bearing housing (46). A flow director (15) 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 along path A1 to the cooling channel in the bearing assembly and the other fluid output aperture supplies cooling fluid along path A2 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.
