ABSTRACT:
An integrated fluid pump for use in circulating a coolant in an x-ray tube is disclosed. The pump includes a pump body, a pump head, and a motor. The pump head defines a pump volume and further includes a fluid inlet, a fluid outlet, and an impeller positioned in the pump volume that is rotatably driven by the motor to receive coolant from the fluid inlet and eject the fluid via the fluid outlet. The pump is structurally integrated with an outer housing of the x-ray tube, the outer housing containing the coolant. In one embodiment, the fluid inlet and a portion of the pump volume are defined by a portion of the outer housing of the x-ray tube. This integration makes the structural completeness of the fluid pump dependent on the outer housing or other suitable x-ray tube component.
