    Abstract: An X-ray inspection system of the present application is capable of blocking the effect of heat from an X-ray source, thereby making it possible to place a heat-sensitive circuit component in the same housing space as the X-ray source. The X-ray inspection system includes a housing 10 provided with an upper housing space 11, in which an X-ray source 32 housed in a cooling container 30 is placed. Due to pressure of a pump 36, a cooling medium circulates between the cooling container 30 and a heat radiating device 33, thereby suppressing the temperature rise of the cooling container 30. Since the cooling container 30 is placed in the upper housing space 11, the upper housing space 11 serves as a cooling space, suppressing the temperature rise. Therefore, heat-sensitive or heat-producing circuit components can be placed in the upper housing space 11.

    Abstract: A liquid metal or spiral groove bearing structure for an x-ray tube and associated process for manufacturing the bearing structure is provided that includes a bearing shaft rotatably disposed in a bearing housing or shell. The shell includes a thrust seal engaged with a sleeve to maintain co-axiality for the rotating liquid metal seal formed in the shell about the shaft. The shaft has a bore for the introduction of a cooling fluid into the bearing assembly in which is disposed a cooling tube. The cooling tube includes turbulence-inducing features to increase the turbulence of the cooling fluid flowing through the cooling tube, consequently enhancing the heat exchange between the cooling fluid and the shaft. This maximizes the heat transfer from the shaft to the oil, allowing materials with lower thermal conductivities, such as non-refractory materials, to be used to form the bearing shaft and shell.

    Abstract: A mechanism for cooling the anode of an x-ray tube using a phase change material to transfer heat away from the anode. The x-ray tube is joined to a sealed heat exchange chamber which contains a liquid metal as a liquid to vapor phase change material (L-V PCM). The back side of the anode is exposed to an interior of the heat exchange chamber, and a jet sprayer inside the heat exchange chamber sprays a liquid of the metal onto the back side of the heated anode. The L-C PCM evaporates on that surface to carry away the heat, and the vapor then condenses back into the liquid on the cool surfaces of the heat exchange chamber. The surfaces of the heat exchange chamber may be cooled by convection cooling. Optionally, pipes containing a circulating cooling fluid may be provide inside the heat exchange chamber.
