Solution Overview
Problem
Existing X-ray generating apparatuses suffer from inefficient heat dissipation, leading to reduced service life due to the slow thermal radiation and small contact area of bearings, which cannot timely remove the heat generated during X-ray production.
Innovation Solution
Incorporation of a heat-conducting member that circulates a cooling medium through the anode target, enhancing heat dissipation efficiency by promptly carrying away heat generated during X-ray production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If conventional X-ray generating apparatus uses thermal radiation and bearing contact for heat dissipation, then the structure is simple, but the heat dissipation efficiency is low and service life is reduced
Solution Approach 1:
The patent introduces a heat-conducting member as an intermediary component between the anode target and the cooling medium. This mediator efficiently transfers heat from the anode target to the circulating cooling medium, significantly improving heat dissipation efficiency without substantially increasing structural complexity
Solution Approach 2:
The patent employs a liquid cooling medium circulating through channels in the heat-conducting member to remove heat from the anode target. This hydraulic cooling system replaces inefficient thermal radiation with forced convection through fluid circulation, achieving superior heat dissipation while maintaining reasonable structural complexity
2Duration of action of stationary object
If bearing contact area is small for heat dissipation, then the device structure is compact, but the heat dissipation speed is slow and service life is reduced
Solution Approach 1:
The patent uses a liquid cooling medium flowing through channels to rapidly remove heat from the anode target. The forced convection of the cooling fluid provides high heat dissipation speed, directly extending the service life of the X-ray generating apparatus by preventing thermal damage to components
Solution Approach 2:
The cooling medium continuously circulates through the heat-conducting member, providing ongoing heat removal during X-ray operation. This continuous cooling action maintains the anode target within safe temperature limits, ensuring sustained operational life of the apparatus
