ABSTRACT:
Heat removal apparatus is provided for an X-ray tube having a frame, a shaft mounted for rotation with respect to the frame, and an anode supported on the shaft for rotation therewith. The apparatus comprises a heat transfer component, which is fixably joined to the frame in closely spaced relationship with an end portion of the rotatable shaft, and further comprises a radially, axially and tilt compliant sealing device, such as a flexible bellows, which is positioned to substantially enclose a space extending between the heat transfer component and a specified end portion of the shaft. A selected thermally conductive liquid metal, such as a gallium alloy, is contained within the enclosed space to provide a path for the flow of heat from the shaft to the heat transfer component, as the shaft and the anode rotate with respect to the frame. Such arrangement also permits expansion of the liquid metal, in the event of freezing.
