Solution Overview
Problem
High-power industrial magnetrons require effective cooling methods to manage heat generated during microwave output, with existing cooling systems facing challenges in reducing liquid leakage and ensuring sufficient cooling capacity, particularly due to external components like pipe joints.
Innovation Solution
A cooling block with multiple refrigerant flow paths and connection paths integrated within the block, eliminating the need for external pipe joints by connecting flow paths internally, thereby reducing the risk of liquid leakage and enhancing cooling capacity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If external pipe joints are used to connect flow paths in the cooling block, then the cooling system can be assembled from separate components, but liquid leakage occurs at the connection portions
Solution Approach 1:
The patent merges multiple separate flow paths into a single integrated cooling block structure. The first and second flow paths are formed within the same cooling block body, eliminating the need for external pipe joints to connect them. This integration maintains manufacturing ease while preventing liquid leakage by removing the external connection interfaces that were prone to leakage.
Solution Approach 2:
The patent embeds multiple flow paths within the internal structure of the cooling block, similar to nested dolls. The first and second flow paths are nested within the cooling block body, with each path contained within the same structural envelope. This nesting approach allows separate flow paths to coexist without requiring external connections, thus preventing leakage while maintaining functional separation.
2Power
If multiple flow paths are added to increase cooling capacity, then sufficient cooling for high power magnetrons is achieved, but the number of external components and connection points increases
Solution Approach 1:
The patent combines multiple flow paths (first and second flow paths) into a single cooling block structure. This merging allows the system to provide enhanced cooling capacity through multiple internal pathways while avoiding the need for proportionally increased external components and connection points, thus reducing overall device complexity.
Solution Approach 2:
The patent utilizes the internal three-dimensional space of the cooling block to accommodate multiple flow paths. By arranging flow paths in different spatial dimensions within the block (e.g., different heights, orientations, or layers), the system achieves multi-path cooling capability without increasing external complexity, as all paths are contained within the same external boundary.
3Ease of manufacture
If pipe joints are used to connect flow paths, then the cooling block can be manufactured in sections, but the connection portions become potential leakage points
Solution Approach 1:
The patent merges the first and second flow paths into a single integrated cooling block, eliminating external pipe joints. This approach maintains manufacturing flexibility by allowing the cooling block to be manufactured using various techniques (casting, machining, additive manufacturing) while simultaneously eliminating the harmful effect of liquid leakage at connection points.
Solution Approach 2:
The patent extracts the flow paths from external separate components and incorporates them directly into the cooling block structure. By taking out the need for external pipe joints and integrating the flow paths within the block itself, the design eliminates leakage points while preserving manufacturing flexibility through various fabrication methods.
