Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If a single condenser is used in the loop type heat pipe, then the device structure is simple, but the heat dissipation capacity is insufficient for high-power electronic components
Solution Approach 1:
The patent divides the condensation function into two separate condensers (first condenser and second condenser) instead of using a single condenser. Each condenser has its own independent liquid pipe and vapor pipe, allowing the heat pipe to handle higher heat loads by distributing the condensation process across multiple units. This segmentation directly increases the heat dissipation capacity while managing the complexity through modular design.
2Power
If multiple flow channels are used to increase heat transfer capacity, then heat dissipation improves, but fluid flow stability and prevention of backflow becomes more difficult
Solution Approach 1:
The patent segments the flow channels into distinct first and second flow channels, each connected to its own condenser. This segmentation allows independent control and optimization of fluid flow in each channel, improving stability while maintaining high heat transfer capacity through parallel flow paths.
Solution Approach 2:
The patent introduces porous bodies as intermediary elements within the flow channels. These porous bodies act as flow regulators that stabilize the working fluid flow, prevent backflow between channels, and ensure reliable operation while allowing high heat transfer capacity through the distributed channel structure.
