Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a wick member with multiple pores is integrated with the refrigerant flow space using a sintering method to distribute liquefied refrigerant, then the refrigerant distribution capability is improved, but the manufacturing complexity and installation complexity increase significantly
Solution Approach 1:
The invention extracts the wick member from the integrated sintered structure and makes it a separate, removable component. This allows the wick member to be independently manufactured and then installed into the refrigerant flow space, significantly simplifying the manufacturing process and installation while maintaining the refrigerant distribution capability through the porous structure.
Solution Approach 2:
The invention divides the heat dissipation apparatus into separate functional components: the heat dissipation plate, the wick member, and the refrigerant flow space. This segmentation allows each component to be optimized and manufactured independently, reducing overall manufacturing complexity while maintaining system performance.
2Ease of manufacture
If the heat dissipation apparatus is horizontally disposed at the top of flat heating elements to transfer heat, then the manufacturing is simplified, but the usage flexibility and adaptability are very limited
Solution Approach 1:
The invention enables the heat dissipation apparatus to adapt to different orientations and configurations. The separated wick member design and the gravitational independence achieved through capillary action allow the apparatus to function effectively in vertical, horizontal, or inclined arrangements, providing dynamic adaptability to various installation scenarios and heating element configurations.
