Abstract
A stationary anode for an X-ray generator, in particular of an X-ray imaging device or an X-ray therapy or spectroscopy device, includes a main anode body and an internal cooling duct, running in the axial direction, for conveying a cooling fluid to a heat exchange surface of the main anode body. A nozzle, disposed at the end of the cooling duct, is inventively positioned with respect to the heat exchange surface via stop elements such that, between the heat exchange surface and the nozzle, a gap is formed which extends over an angular range of 360° about the axial direction.

A stationary anode for an X-ray generator, comprising:
- a main anode body;
- and
- an internal cooling duct, running in an axial direction, to convey a cooling fluid to a heat exchange surface of the main anode body that is disposed opposite a target, wherein a nozzle, disposed at an end of the internal cooling duct, is positioned with respect to the heat exchange surface via stop elements such that, between the heat exchange surface and the nozzle, a gap is formed extending over an angular range of 360° about the axial direction, a central region of the heat exchange surface being conically shaped and forming a conically shaped region disposed opposite a funnel-shaped outlet orifice of the nozzle, wherein the conically shaped region of the heat exchange surface extends into the funnel-shaped outlet orifice.
An X-ray generator, comprising:
- an electron-bombardable stationary anode, including
- a main anode body and
- an internal cooling duct, running in an axial direction, to convey a cooling fluid to a heat exchange surface of the main anode body that is disposed opposite a target, wherein a nozzle, disposed at an end of the internal cooling duct, is positioned with respect to the heat exchange surface via stop elements such that, between the heat exchange surface and the nozzle, a gap is formed extending over an angular range of 360° about the axial direction, a central region of the heat exchange surface being conically shaped and forming a conically shaped region disposed opposite a funnel-shaped outlet orifice of the nozzle, wherein the conically shaped region of the heat exchange surface extends into the funnel-shaped outlet orifice.
