ABSTRACT:
An X-ray tube housing with integrated cooling passages in the walls of the X-ray tube housing, through which a liquid or gas coolant is circulated and the heat is transferred from the X-ray tube housing to an external cooler. The integrated cooling passages are created around the perimeter of the X-ray tube housing as the X-ray tube housing is formed. For a rotating anode X-ray tube using an oil coolant, the path of heat transfer is from the anode to the glass insert and oil by the means of radiation. The oil that is in contact with the glass insert conducts heat away form the insert to the X-ray tube housing which is then cooled by the integrated cooling passages located within the X-ray tube housing through which fluid is passed to an external fluid cooling system.
