摘要： An x-ray tube assembly (16) includes a housing (40) and an insert frame (52) supported within the housing (40), such that the insert frame (52) defines a substantially evacuated envelope in which cathode (56) and anode (54) assemblies operate to produce x-rays. An x-ray transmissive window assembly (70) extends between and in a fluid-tight relationship with the housing (40) and the insert frame (52). The window assembly (70) includes an insert window (72) brazed to the insert frame (52), a top plate (76), which is connected to and substantially surrounded by a flange (78), where the flange (78) is fastened to the x-ray tube housing (40). An annular side plate (86) is connected to a fluid-tight relationship with both the insert frame/window interface (74) and the flange (78). The window assembly (70) cools the window through enhanced heat transfer while preventing housing coolant from contacting the insert window (72), thereby eliminating coolant carbonization on the window (72) and enhancing x-ray beam quality.

摘要： An x-ray tube (10) includes an evacuated envelope (14), a cathode assembly (20) located in the evacuated envelope and a disk shaped anode assembly (18) located in the evacuated envelope in operative relationship with the cathode assembly for generating x-rays (40). The anode assembly includes an axis of rotation (26) and a target substrate (28) facing the cathode assembly. A heat pipe (33) is located within the anode assembly (18). The heat pipe is comprised of an evacuated shell (60) and is vacuum sealed at a first end (70) of the shell and at a second end (72). A material (80, 82) within the shell is a working fluid for the heat pipe at x-ray tube operating conditions. A porous wick (62) is located within the shell and the wick has a length extending from the first end (70) of the shell to the second end (72) of the shell. A shield (64) is attached to the wick to reduce working fluid loss out of the wick during x-ray tube operation.
