Abstract
A system for passive thermal control of an X-ray tube is provided. The system includes an X-ray tube having an electron beam target and including a rotary bearing assembly supporting the electron beam target in rotation. The rotary bearing assembly includes a stationary shaft and a bearing sleeve configured to rotate with respect to the stationary shaft during operation of the X-ray tube. The rotary bearing assembly also includes a first coolant flow path extending through a center of the stationary shaft and a second coolant flow path disposed through a radially inward portion of the stationary shaft disposed about the center of the stationary shaft. The rotary bearing assembly further includes a flow control valve configured to passively regulate flow of coolant through the second coolant flow path based on a pressure of the coolant.
