6results about "X-ray tube cooling method" patented technology

The disclosure provides an X-ray conversion target. The X-ray conversion target includes target body and a target part (5) disposed within the target body, the target part having a first face configured to produce X-rays; wherein, the X-ray conversion target further comprises a cooling passage (1) having a side wall, at least a part of the side wall being consisted of a portion of the target part.

Anodes with integrated heat exchangers, x-ray tubes including the same, and methods of manufacturing anodes are disclosed. An anode for an x-ray tube can include a body portion defining an inner channel, an outer channel, and a radial channel. The radial channel can be configured to direct a coolant between the inner channel and the outer channel.

To provide an X-ray tube that can operate with higher power output and / or less wear. [Solution] An X-ray tube is provided, wherein a target 11 is formed on the end face 10 of an anode head 6 having a central axis ZA, and during operation, electrons collide with the target 11 in an excitation region 9, and the anode head 6 provides a flow path for cooling fluid that leads from at least one inlet connection through a radially outer section 20, further through a cooling gap 21, and further through a radially inner section 22 to at least one outlet connection, wherein the excitation region 9 of the target 11 is substantially ring-shaped, and in a region 26 of the anode head 6 located on the opposite side of the excitation region 9 of the target 11, the local heights H1, H2 of the cooling gap 21 gradually increase from radially outward to radially inward.

An X-ray tube (1), comprising a source (4) for the release of electrons and an anode head (6) with a central axis (ZA), wherein a target (11) is formed on an end face (10) of the anode head (6), onto which the electrons in an excited region (9) impinge during operation, wherein the anode head (6) provides a flow path (16) for a cooling fluid, which leads from at least one inlet port (14a) via a radially outer section (20), further via a cooling gap (21), and further via a radially inner section (22) to at least one outlet port (15a), is characterized in that the excited region (9) of the target (11) is essentially annular, and that in a region (26) of the anode head (6) opposite the excited region (9) of the target (11) a local height (H1, H2) of the cooling gap (21) extends from radially outside to radially steadily increases towards the inside.The X-ray tube according to the invention can be operated with higher power and / or less wear.

An x-ray tube includes a source for releasing electrons and an anode head with a central axis. A target is formed on an end face of the anode head, on which target during operation the electrons impinge in an excited region. The anode head provides a flow path for a cooling fluid, which flow path leads from at least one inlet connection via a radially outer portion, further via a cooling gap, and further via a radially inner portion to at least one outlet connection. The excited region of the target is essentially annular, where in a region of the anode head opposite the excited region of the target, a local height of the cooling gap increases continuously from radially outside to radially inside. The x-ray tube can be operated at a higher power and / or with less wear.
