X-ray Generator Insulating Block Recess Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing X-ray generator structures face challenges in maintaining insulating characteristics and heat dissipation while preventing electrical discharging, particularly due to the configuration of the insulating oil and power source unit, which can lead to disturbances in the electric field and potential discharging.
Innovation Solution
The X-ray generator design includes an X-ray tube accommodation portion with an insulating block having a recess portion and a communication hole, allowing the insulating liquid to be enclosed in a region not facing the X-ray tube, thereby improving insulating and heat dissipation characteristics, and a projecting portion to isolate potential discharging origins, with a sealing member capable of deformation to manage temperature changes and internal pressure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a configuration for improving insulating characteristics or heat dissipation characteristics of insulating liquid is provided inside an X-ray tube accommodation portion, then insulating characteristics and heat dissipation characteristics are improved, but disturbance occurs in an electric field inside the X-ray tube accommodation portion and discharging may occur
Solution Approach 1:
The patent extracts the configuration for improving insulating characteristics (such as heat dissipation structures or insulating enhancements) from the X-ray tube accommodation portion and relocates it to the insulating block side. This separation removes the harmful electric field disturbance from the accommodation portion while preserving the beneficial insulating and heat dissipation effects in the insulating block where they do not interfere with the electric field.
2Reliability
If a configuration for improving insulating characteristics or heat dissipation characteristics of insulating liquid is provided on an insulating block side, then insulating characteristics and heat dissipation characteristics are improved, but discharging may occur between this configuration and the power source unit
Solution Approach 1:
The patent applies local quality by creating a differentiated structure within the insulating block: a first space facing the X-ray tube accommodation portion and a second space containing the power source unit. By providing the insulating enhancement configuration only in the second space (away from the power source unit) and using a communication portion to connect the two spaces, the patent locally improves insulating characteristics without creating discharging paths between the configuration and the power source unit.
3Reliability
If the depth of the recess portion is increased to improve insulating characteristics, then insulating characteristics are improved, but the distance between the high-voltage generation circuit and the second space decreases, increasing the risk of discharging
Solution Approach 1:
The patent resolves this contradiction by changing the dimensional approach: instead of increasing depth (one dimension), it increases the width of the recess portion. This allows the insulating liquid to extend further laterally, improving insulating characteristics around the high-voltage generation circuit, while maintaining adequate vertical distance between the circuit and the second space, thus preventing discharging.

Function Achieved in This Case
This configuration effectively curbs electrical discharging and maintains the stability of the X-ray generator by enhancing insulating and heat dissipation properties, ensuring reliable operation while managing temperature and pressure changes.
Implementation Method 1
insulating liquid comes into direct contact with the X-ray tube, it is exposed to a state at a high temperature
Implementation Method 2
insulating properties of this insulating liquid are more likely to deteriorate than those of the solid insulating block

AI summary
An X-ray generator includes an X-ray tube, an X-ray tube accommodation portion, and a power source unit having an internal substrate supplying a voltage to the X-ray tube sealed inside an insulating block. A first space is defined by an upper surface of the insulating block and an inner surface of the X-ray tube accommodation portion. A second space is defined by a recess portion opening to the outside formed on a side surface of the insulating block and a sealing member sealing an opening of the recess portion. A communication hole causing the first space and the second space to communicate with each other is provided in the insulating block. Insulating oil is enclosed in the first space and the second space. A depth of the recess portion is smaller than a width of the recess portion.
