Engineering Contradiction Analysis
1Temperature
If multiple openings are provided for cooling liquid flow, then cooling efficiency is improved, but radiation leakage risk increases
Solution Approach 1:
The container is divided into multiple separate openings for cooling liquid flow instead of using a single large opening. Each opening is individually shielded, allowing the system to achieve effective cooling while minimizing radiation leakage through multiple small protected pathways rather than one large unprotected opening.
Solution Approach 2:
Shielding means are introduced as intermediary elements between the cooling liquid openings and the external environment. These shielding structures (such as collimators or protective barriers) allow the cooling function to proceed while blocking harmful X-ray radiation, thus mediating between the conflicting requirements of cooling efficiency and radiation protection.
2Object-affected harmful factors
If shielding materials are added to openings, then radiation prevention is improved, but cooling efficiency may deteriorate
Solution Approach 1:
The shielding materials are strategically positioned and configured to provide radiation protection specifically at the opening areas where cooling liquid flows, rather than uniformly across the entire container. This localized approach ensures that radiation prevention is achieved without unnecessarily impeding the cooling liquid flow paths, maintaining thermal management effectiveness.
