Novel high-capacity x-ray bulb tube cooling structure

Abstract

The invention discloses a novel high-capacity x-ray bulb tube cooling structure which comprises a tungsten-molybdenum composite target disk, a first molten metal bearing rotor, a second molten metal bearing rotor and a stator component. One end of the tungsten-molybdenum composite target disk is connected with the first molten metal bearing rotor, the second molten metal bearing rotor is installedat the end, away from the tungsten-molybdenum composite target disk, of the first molten metal bearing rotor, the stator component is installed at the end, away from the first molten metal bearing rotor, of the second molten metal bearing rotor, and a kovar shell is arranged on the end, away from the second molten metal bearing rotor, of the stator component along the side wall of the circumference. The amount of heat generated by the target disk and emitted to the bearing can be reduced as much as possible, the heated generated on the target disk is brought away by a cooling fin as much as possible, the calorific capacity of the target disk is larger, if the heat on the target disk is not higher, an x-ray tube can work all the time, and meanwhile the service lie of a while anode assemblyis longer.

Description

Technical field [0001] The invention relates to the technical field of heat dissipation structures, in particular to a new type of heat dissipation structure for a large-capacity X-ray tube. Background technique [0002] At present, all high-power X-ray tubes are trying to solve the problem of heat storage and heat dissipation of the target disk. For example, the current 0 megabytes, 7.5 megabytes and 8 megabytes on the market adopt different heat dissipation methods, and their main purpose Is to reduce the temperature of the target plate and the bearing, so that the life of the tube will increase. [0003] As we all know, the main reason why high-power X-ray tubes are high-power is that the target plate has better heat dissipation and heat storage, so that when the high-power electron beam hits the target plate, the target plate will not be damaged. The so-called bad means If the surface temperature of the target is too high, the target will melt. The result of the melting of the...

Problems solved by technology

[0003] As we all know, the main reason why high-power X-ray tubes are high-power is that the heat dissipation and heat storage of the target disk are better, so that the target disk will not be damaged when the high-power electron beam hits the target disk. If the surface temperature of the target disk is too high, the target disk will melt. As a result of the melting of the target disk, the X-ray quality will be reduced, and it will be scrapped at last. If the bearing temperature is too high during work, the bearing will also break down in advance. It was scrapped, so we designed a new type of large-capacity x-ray tube heat dissipation structure to solve the above problems
