Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional liquid-cooled dissipating system uses fixed pump speed control, then the system structure is simple, but the heat dissipation effect is insufficient and cannot meet different heat dissipation requirements of multiple heat sources
Solution Approach 1:
The flow channel is designed with flexible walls that can dynamically change their cross-sectional area and shape in response to local heat dissipation requirements. This dynamic adaptation allows different regions of the flow channel to automatically adjust their flow resistance, directing more coolant flow to areas with higher heat generation without requiring complex external control systems
Solution Approach 2:
The flexible flow channel structure enables the system to self-regulate coolant distribution based on local thermal conditions. The flexible walls automatically deform in response to pressure differences caused by varying heat dissipation demands, creating a self-adjusting flow distribution mechanism that eliminates the need for external flow control devices at each heat source
2Productivity
If the heat transferring liquid flows through the conventional liquid-cooled dissipating system, then the liquid can transfer heat, but abnormal flow states occur due to flow resistance and system structure, reducing heat dissipation effect
Solution Approach 1:
The flow channel walls are constructed from flexible materials that can deform to smooth out flow disturbances and abnormal flow states. This flexibility allows the channel to adapt to pressure variations and maintain laminar flow conditions, preventing flow resistance issues and ensuring stable, reliable heat transfer throughout the system
Solution Approach 2:
The flexible flow channel structure allows local parameters such as cross-sectional area and flow velocity to change dynamically along the flow path. This parameter variation optimizes the flow state at different locations, maintaining efficient heat transfer by adapting to local thermal and hydraulic conditions while preventing abnormal flow states
