Embodiment Construction

[0034] figure 1 shown for use in figure 2 The nozzle 1 of the stationary anode 10 is shown in detail in .

[0035] The nozzle 1 has a cooling channel K that tapers in the axial direction A for conveying a cooling fluid, in particular fully desalinated water, which diverges at the end into a funnel-shaped outflow opening 5 .

[0036] Furthermore, the nozzle has three stop elements 3 in the form of radially protruding webs 7, wherein figure 1 Only one of the stop elements is located in the section plane shown. The stop elements 3 formed as webs 7 are arranged circumferentially at an angular distance of 120° and serve to fix and center the nozzle 1 relative to the anode base body 11 of the stationary anode 10 so that the cooling channel K is fixed within the stationary anode 1 . Mind stretched. For this purpose, the nozzle 1 is connected at its end facing away from the outflow opening 5 with a delivery pipe 13 which delimits the cooling channel K in sections.

Abstract

The invention relates to a stationary anode (10) for an X-ray radiator, in particular for an imaging X-ray device or an X-ray device for radiotherapy or spectroscopy, having an anode base body ( 11) and built-in cooling channels (K) extending in the axial direction (A) to guide the cooling fluid to the heat exchange surface (17) of the anode base body (11). According to the invention, the nozzles (1) arranged on the end side of the cooling channel (K) are positioned with respect to the heat exchange surface (17) by means of stop elements (3, 7, 15) such that at the heat exchange surface ( 17) and the nozzle (1) form a gap which extends around the axial direction (A) over an angular range of 360°.

Description

technical field [0001] The invention relates to a fixed anode for an X-ray radiator, especially for an X-ray imaging device or an X-ray device for radiotherapy or spectroscopy, said fixed anode comprising an anode base body and a built-in . Cooling channels extending in the axial direction for guiding a cooling fluid to the heat exchange surface of the anode base body. The invention also relates to an x-ray radiator with a fixed anode configured in this way. Background technique [0002] X-ray radiators (also called: X-ray tubes) are known from various fields of X-ray technology, in particular from the fields of imaging, radiotherapy or spectroscopy, which X-ray radiators have a fixed anode, i.e. The anode is fixedly and in particular fixedly mounted in the vacuum housing of the x-ray radiator. In order to achieve a correspondingly high power it is partly necessary to actively flow a cooling fluid through the stationary anode. For conducting the cooling fluid, stationary ...
