Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If intermediate members are used between heat radiators and refrigerant flow paths, then structural stability is improved, but cooling performance deteriorates and dimensions increase
Solution Approach 1:
The patent removes intermediate members (such as insulating plates or spacing structures) that were previously placed between the heat radiators and refrigerant flow paths. By extracting these unnecessary components, the heat radiators come into direct contact with the refrigerant, eliminating thermal resistance and improving cooling efficiency while reducing overall structure dimensions.
Solution Approach 2:
The patent merges the heat radiator structure with the refrigerant flow path structure, allowing them to be in direct contact without intermediate members. This integration enables efficient heat transfer from the reactors through the heat radiators directly to the refrigerant, improving cooling performance while reducing the number of components and overall size.
2Reliability
If intermediate members are used between heat radiators and refrigerant flow paths, then structural stability is improved, but device dimensions increase
Solution Approach 1:
The patent extracts and removes intermediate members that were occupying space between the heat radiators and refrigerant flow paths. This elimination of unnecessary components directly reduces the overall dimensions of the cooling structure while maintaining functional integrity through direct contact between heat radiators and refrigerant.
Solution Approach 2:
By merging the heat radiator and refrigerant flow path structures into direct contact, the patent eliminates the space that would have been occupied by intermediate members. This consolidation reduces the overall volume and dimensions of the cooling system while improving heat transfer efficiency.
3Temperature
If pressure application is used to enhance heat transfer, then cooling performance is improved, but structural complexity and additional components are required
Solution Approach 1:
The patent designs the cooling structure to achieve efficient heat transfer through its inherent geometric configuration and direct contact between components, without requiring external pressure application mechanisms. The structure itself facilitates optimal thermal contact, eliminating the need for additional actuators, sensors, or control systems that would be required to apply and regulate pressure.
Solution Approach 2:
The patent removes pressure application mechanisms and related control systems from the cooling structure. By designing the heat radiators and refrigerant flow paths to be in direct contact through clever structural arrangement, the system achieves effective cooling without the complexity of active pressure control systems.
