INTEGRAL LIQUID-COOLANT PASSAGEWAYS IN AN X-RAY TUBE

摘要

Integral liquid-coolant passageways in an x-ray tube. In one example embodiment, an x-ray tube includes a can at least partially defining an evacuated enclosure, a cathode at least partially positioned within the evacuated enclosure, and an anode at least partially positioned within the evacuated enclosure. The can has first integral liquid-coolant passageways formed therein. The can is configured to have a liquid coolant circulated through the first integral liquid-coolant passageways to thereby cool the can without the can being submersed in a liquid coolant.

主权项

1. A process for forming an x-ray tube can, the process comprising:
forming a wax model of an x-ray tube can having integral liquid-coolant passageways; coating all internal and external surfaces of the wax model with a silica slurry; heating the coated wax model to harden the silica coating into a shell and to remove the wax model leaving the shell hollow; filling the hollow shell with a molten metal; cooling the molten metal to solidify the metal; and removing the shell resulting in a metal x-ray tube can having integral liquid-coolant passageways.
