Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the heat exchanger uses a conventional design with channels stacked horizontally and coolant passes located between them, then the structure is simple and easy to manufacture, but the coolant liquid flow is insufficient in passes farthest from the center, causing local boiling
Solution Approach 1:
The heat exchanger is divided into multiple independent channels stacked horizontally, with each channel having its own coolant passes. This segmentation allows the coolant to be distributed more effectively to passes farthest from the center, preventing local boiling while maintaining a modular structure that is relatively simple to manufacture.
Solution Approach 2:
The invention transitions from a single-plane coolant distribution system to a multi-dimensional system by stacking channels horizontally and positioning coolant passes between them. This three-dimensional arrangement ensures that coolant reaches all passes including those farthest from the center, improving cooling reliability without excessive complexity.
2Ease of manufacture
If the heat exchanger uses passes located between horizontally stacked channels, then the manufacturing process is simplified, but the coolant liquid does not cool the passes farthest from the center adequately, leading to local boiling
Solution Approach 1:
The heat exchanger design ensures that each coolant pass, including those farthest from the center, receives adequate cooling by positioning passes between horizontally stacked channels. This creates localized quality in temperature distribution, where each region receives appropriate coolant flow, preventing local boiling while maintaining ease of manufacture through the regular stacked structure.
3Volume of moving object
If the heat exchanger uses a compact design with horizontal channel stacking, then the space utilization is improved, but the coolant liquid flow distribution becomes uneven, causing inadequate cooling in distant passes
Solution Approach 1:
The compact heat exchanger is segmented into multiple horizontally stacked channels, each with dedicated coolant passes positioned between the channels. This segmentation enables efficient coolant distribution to all passes including those farthest from the center, maintaining both compact size and high cooling productivity.
Solution Approach 2:
By stacking channels horizontally and positioning coolant passes between them in three-dimensional space, the invention achieves compact volume utilization while ensuring even coolant flow distribution across all passes, thereby maintaining high cooling efficiency despite the compact design.
