LARGE SURFACE AREA X-RAY TUBE SHIELD STRUCTURE

The shield includes a plurality of cooling fins to improve overall cooling of the x-ray tube and the shield so as to extend the life of the x-ray tube and related components. When immersed in a reservoir of coolant fluid, the fins facilitate improved heat transfer by convection from the shield to the to the coolant fluid. The cooling effect achieved with the cooling fins is further augmented by a convective cooling system provided by a plurality of fluid passageways formed within the shield, which are used to provide a fluid path to the coolant. In particular, a cooling unit takes fluid from the reservoir, cools the fluid, then circulates the cooled fluid through the fluid passageways. One or more depressions of "V" shaped cross section defined on the surfaces of the fluid passageways serve to facilitate nucleate boiling of the coolant in the passageway, and thereby materially increase the heat flux through the passageway to the coolant. Additionally, one or more extended surfaces disposed on the surfaces of the fluid passageways also facilitate a relative increase in the rate of heat transfer from the shield structure to the coolant. After flowing through the fluid passageway, the coolant is then discharged from the fluid passageways and directed over the cooling fins. In some embodiments, the fluid passageways are oriented so as to provide a greater heat transfer rate in certain sections of the shield than in other sections. Also disclosed is an improved braze joint for connecting the shield to the x-ray tube housing.

X-ray tube cooling system and X-ray tube generator

A dual fluid cooling system for high power x-ray tubes

A cooling system (300) for use with high-power x-ray tubes (200). The cooling system (300) includes a dielectric coolant (304) disposed in the x-ray tube housing (202) so as to absorb heat dissipated by the stator (400) and other electrical components, as well as absorbing some heat from the x-ray tube itself. To improve heat absorption from the stator (400) and the x-ray tube (200), the dielectric coolant (304) is circulated throughout the housing by a circulating pump (306). The cooling system also includes a coolant circuit employing a pressurized water/glycol solution as a coolant (314). Pressurization of the water/glycol solution is achieved by way of an accumulator (500) which, by pressurizing the coolant (314) to a desired level, raises its boiling point and capacity to absorb heat. A coolant pump (308) circulates the pressurized coolant (314) through a fluid passageway (216) defined in an aperture (206) of the x-ray tube (200) and through a target cooling block (302) disposed proximate to the x-ray tube (200) in the y-ray tube housing (202), so as to position the coolant to absorb some of the heat generated at the aperture (206) by secondary electrons, and the heat generatd in the target cooling block (302) by the target anode (210) of the x-ray tube (200). The target cooling block (302) is in contact with the dielectric fluid (304) so that some of the heat absorbed by the dielectric coolant (304) is transferred to the coolant (314) flowing through the target cooling block (302). The heated coolant is then passed through an air/water radiator (310) where a flow of air serves to remove some heat from the coolant (314). Thus cooled, the coolant then exits the radiator (310) to repeat the cycle.

Large surface area x-ray tube shield structure

An improved x-ray tube cooling system is disclosed. The system utilizes a shield structure that is connected between a cathode cylinder and an x-ray tube housing and is disposed between the electron source and the target anode. The shield includes a plurality of cooling fins to improve overall cooling of the x-ray tube and the shield so as to extend the life of the x-ray tube and related components. When immersed in a reservoir of coolant fluid, the fins facilitate improved heat transfer by convection from the shield to the to the coolant fluid. The cooling effect achieved with the cooling fins is further augmented by a convective cooling system provided by a plurality of fluid passageways formed within the shield, which are used to provide a fluid path to the coolant. In particular, a cooling unit takes fluid from the reservoir, cools the fluid, then circulates the cooled fluid through the fluid passageways. One or more depressions of "V" shaped cross section defined on the surfaces of the fluid passageways serve to facilitate nucleate boiling of the coolant in the passageway, and thereby materially increase the heat flux through the passageway to the coolant. Additionally, one or more extended surfaces disposed on the surfaces of the fluid passageways also facilitate a relative increase in the rate of heat transfer from the shield structure to the coolant. After flowing through the fluid passageway, the coolant is then discharged from the fluid passageways and directed over the cooling fins. In some embodiments, the fluid passageways are oriented so as to provide a greater heat transfer rate in certain sections of the shield than in other sections. Also disclosed is an improved braze joint for connecting the shield to the x-ray tube housing.

Heat sink for x-ray tube anode

Disclosed is an X-ray tube (100) having an electron source (106) and anode (200) disposed therein. The anode includes a target surface (204) positioned to receive electrons ('e') emitted by the electron source (106). A thermal structure (208) is interfaced directly with the anode (200). The thermal structure (208) defines a fluid passageway (211) that is configured to receive and circulate a coolant. A thermally conductive porous matrix (230) is disposed within the fluid passageway (211) so as to facilitate the transfer of heat generated (220) at the target surface (204) to the coolant.

X射线转换靶

本发明公开了一种X射线转换靶。X射线转换靶包括靶体和靶部，靶部设置在靶体内部，靶部具有第一面，所述第一面配置用于产生X射线；其中，X射线转换靶还包括冷却通道，所述冷却通道的侧壁至少部分由靶部的一部分构成。

Rotating anode x-ray tube

A rotating anode (10) has an improved separator (52) arranged within a coolant passage (50) which is formed inside the rotating anode. A cylindrical target has an outer periphery whose axial length (L3) is in a range between 20 and 100 millimeters. The separator (52) has a proximal surface (82), a distance (G) between the proximal surface (82) and a must-cooled surface (92) being in a range between 0.1 and 3.0 millimeters. The axial length (L2) of the proximal surface (82) is not greater than five millimeters. Thus, since the axial length (L2) of the proximal surface (82) is set to be small, the load of a rotary driving source would be not so large even with a high-speed rotation of the rotating anode (10). When using an electric motor as the rotary driving source, it is not necessary to exchange the capacity of a motor diver for a larger one.

Large surface area x-ray tube shield structure

An improved x-ray tube cooling system is disclosed. The system utilizes a shield structure that is connected between a cathode cylinder and an x-ray tube housing and is disposed between the electron source and the target anode. The shield includes a plurality of cooling fins to improve overall cooling of the x-ray tube and the shield so as to extend the life of the x-ray tube and related components. When immersed in a reservoir of coolant fluid, the fins facilitate improved heat transfer by convection from the shield to the to the coolant fluid. The cooling effect achieved with the cooling fins is further augmented by a convective cooling system provided by a plurality of fluid passageways formed within the shield, which are used to provide a fluid path to the coolant. In particular, a cooling unit takes fluid from the reservoir, cools the fluid, then circulates the cooled fluid through the fluid passageways. One or more depressions of "V" shaped cross section defined on the surfaces of the fluid passageways serve to facilitate nucleate boiling of the coolant in the passageway, and thereby materially increase the heat flux through the passageway to the coolant. Additionally, one or more extended surfaces disposed on the surfaces of the fluid passageways also facilitate a relative increase in the rate of heat transfer from the shield structure to the coolant. After flowing through the fluid passageway, the coolant is then discharged from the fluid passageways and directed over the cooling fins. In some embodiments, the fluid passageways are oriented so as to provide a greater heat transfer rate in certain sections of the shield than in other sections. Also disclosed is an improved braze joint for connecting the shield to the x-ray tube housing.
