Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a conventional cooling block with straight refrigerant flow path is used, then the structure is simple, but the cooling capacity is insufficient when heat generation amount increases
Solution Approach 1:
The patent applies a helical groove configuration in the refrigerant flow path instead of a straight path. This curved/helical structure increases the surface area contact between the refrigerant and the cooling block, enhancing heat transfer efficiency and cooling capacity while maintaining manufacturing feasibility through standard machining processes
2Device complexity
If air cooling is used for low output magnetrons, then the structure is simple, but it cannot be used for high output industrial magnetrons with large heat generation
Solution Approach 1:
The patent transitions from air cooling to liquid refrigerant cooling by implementing a closed-loop refrigerant circulation system with flow paths in the cooling block. This hydraulic cooling approach provides sufficient cooling capacity for high-output industrial magnetrons while maintaining reasonable structural complexity
3Reliability
If the refrigerant flow path is optimized for high heat generation, then the cooling capacity increases, but the manufacturing complexity increases
Solution Approach 1:
The patent optimizes specific parameters of the helical groove configuration including groove depth, width, pitch, and helix angle to maximize cooling capacity. By carefully controlling these geometric parameters, the system achieves enhanced heat transfer without excessive manufacturing complexity
