Abstract
An x-ray emitter includes an x-ray tube and an x-ray emitter housing. In an embodiment, the x-ray tube includes an evacuated x-ray tube housing, a cathode for emitting electrons and an anode for generating x-rays as a function of the electrons. Further, in an embodiment, the x-ray emitter housing includes the x-ray tube and outside of the x-ray tube, a gaseous cooling medium. In an embodiment, the x-ray emitter further includes a compressor for a forced convection of the gaseous cooling medium for cooling the x-ray tube, a pressure ratio between the intake side and pressure side of the compressor being greater than 1.3.
Claims18
An x-ray emitter, comprising:
- an x-ray tube, the x-ray tube including a cathode for emitting electrons, an anode for generating x-rays as a function of the electrons, and an evacuated x-ray tube housing including an x-ray beam exit window;
- an x-ray emitter housing, housing the x-ray tube and including a gaseous cooling medium external to the x-ray tube;
- a compressor configured to cause a forced convection of the gaseous cooling medium for cooling the x-ray tube, a pressure ratio between an intake side and a pressure side of the compressor being greater than 1.3;
- and
- a cooling plate including a number of holes for impingements cooling,
- wherein the gaseous cooling medium is configured to cool the x-ray tube without a liquid cooling medium, and
- wherein the cooling plate is aligned relative to the x-ray beam exit window so that a gaseous flow directed through the cooling plate as a function of the forced convection strikes the x-ray beam exit window for the impingement cooling.
