X-ray Tube Insulating Tube Base Section Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional X-ray tube devices suffer from X-ray attenuation and reduced inspection accuracy due to insulating oil acting as a shield and filter, particularly at larger emission angles, leading to non-uniform X-ray intensity and reduced fan-shaped zone coverage.
Innovation Solution
The X-ray tube device employs a cylindrical glass envelope within an insulating tube immersed in oil, with a base section forming a fan-shaped space that allows X-rays to pass directly from the tube to an aperture emission window, minimizing oil interaction and preventing attenuation, and using epoxy resin for insulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the insulating tube is immersed in insulating oil, then electrical insulation is improved, but X-ray attenuation increases
Solution Approach 1:
The patent extracts the insulating oil from the path of the X-ray beam by positioning the emission window at the bottom of the container, allowing X-rays to exit through a region free of oil interference while maintaining oil immersion for electrical insulation of the X-ray tube
Solution Approach 2:
The patent introduces an X-ray transmission window as an intermediary structure that allows X-rays to pass from the vacuum environment to the oil-filled environment without direct interaction with the insulating oil, thereby maintaining both insulation and X-ray transmission
2Area of stationary object
If the emission angle is increased to expand fan-shaped zone coverage, then inspection coverage is improved, but X-ray intensity uniformity deteriorates
Solution Approach 1:
The patent removes the insulating oil from the X-ray emission path by positioning the emission window at the bottom, eliminating the oil's filtering effect that caused non-uniform intensity distribution across different emission angles
Solution Approach 2:
The patent creates a localized X-ray transmission path through the emission window that provides optimal transmission conditions for all emission angles, ensuring uniform intensity across the entire fan-shaped zone while maintaining oil immersion for insulation

AI summary
An X-ray tube device in one embodiment has an X-ray tube and a container storing the X-ray tube, filled with insulating oil, and having an X-ray emission window. The X-ray tube includes a cylindrical glass envelope holding an anode and a cathode opposite to each other and keeping them in vacuum, and an insulating tube fit over the glass envelope and having an X-ray transmission section. The insulating tube has a base section attached to the container. The base section defines a space communicating between the X-ray transmission section of the insulating tube and the X-ray emission window of the container, and has a container-side end fixed to the container in a liquid-tight manner.
