Engineering Contradiction Analysis
1Productivity
If a conventional two-phase heat dissipation method is used, then heat dissipation is achieved, but the two-phase circulation efficiency is low
Solution Approach 1:
The heat dissipation plate is divided into distinct first, second, and third heat dissipation zones with different channel configurations. The second heat dissipation channel uses a mesh-shaped structure while the third uses a strip-shaped structure, segmenting the heat dissipation function to optimize two-phase circulation efficiency in different regions of the plate.
Solution Approach 2:
Different heat dissipation zones are provided with different channel structures tailored to local requirements. The mesh-shaped channels in the second zone provide different flow characteristics compared to the strip-shaped channels in the third zone, allowing each region to optimize its local heat dissipation performance.
2Loss of energy
If heat dissipation efficiency is improved through complex channel structures, then heat dissipation effect is enhanced, but device complexity increases
Solution Approach 1:
The second heat dissipation channel employs a mesh-shaped channel structure that functions as a porous medium, enabling efficient vapor diffusion and two-phase flow without requiring complex mechanical components. This porous structure enhances heat dissipation while maintaining manufacturing feasibility.
