Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electron beam emitters face excessive heat issues, particularly at the connector area, which can lead to elevated temperatures exceeding 70°C, compromising the optimal performance and longevity of the connector area, necessitating an efficient and cost-effective cooling solution.
Innovation Solution
An electron beam emitter design incorporating a cooling flange with an interior channel extending between an inlet and outlet port, providing efficient cooling of the high voltage connector assembly, featuring a U-shaped cross-section for direct contact with the housing and sealed by O-rings to prevent fluid leakage, ensuring even fluid flow and turbulence-free circulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If external cooling is provided for the exit window, then the stability and operating life time of the exit window is improved, but the temperature at the connector area still exceeds 70°C compromising optimal performance
Solution Approach 1:
The cooling system is segmented into two independent parts: a cooling window for the exit window area and a cooling flange for the connector area. This segmentation allows each part to be cooled independently, resolving the contradiction by providing targeted cooling to the connector area without compromising the exit window cooling effectiveness.
Solution Approach 2:
The cooling flange acts as an intermediary cooling component that intercepts heat transfer from the main body to the connector area. By placing this intermediate cooling structure at the connector area, heat is removed before it can significantly raise the connector temperature, thus maintaining optimal performance while allowing the exit window to be cooled separately.
2Device complexity
If a simple, low-cost cooling solution is provided for the connector area, then the device complexity and cost are reduced, but effective cooling below 50°C may not be achieved
Solution Approach 1:
The cooling flange serves multiple functions: it provides structural support for the connector assembly, creates a fluid tight seal through its engagement with the housing opening, and simultaneously acts as a heat sink through its internal cooling channels. This multi-functionality achieves effective cooling without adding significant complexity or cost to the device.
Solution Approach 2:
The cooling flange merges the structural support function with the cooling function into a single integrated component. By combining these functions, the patent avoids the need for separate structural and cooling components, thereby reducing device complexity and cost while maintaining effective cooling performance below 50°C.

Implementation Method 2
The cross section of said cooling flange is essentially U-shaped such that said interior channel of said cooling flange is sealed by the outer surface of the housing. Hence, efficient cooling is provided since the wall of the housing is in direct contact with the cooling fluid flowing within said cooling flange
