Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the vapor pipe is coupled perpendicularly to the heat receiving jacket (large bending angle), then the structural simplicity is maintained, but the pressure loss increases and cooling performance degrades
Solution Approach 1:
The heat receiving jacket is designed with a curved surface (semicircular or circular cross-section) instead of a flat surface. The vapor pipe is coupled to this curved surface at an inclined angle, which reduces the bending angle of the vapor flow path. This curvature design reduces local pressure loss coefficients and improves cooling performance while maintaining structural simplicity.
2Quantity of substance
If heat generating objects are mounted with high density, then the space utilization is improved, but the inner pressure increases and pressure resistance performance degrades
Solution Approach 1:
The curved surface design of the heat receiving jacket disperses the pressure generated by high-density heat generating objects across a larger area. The semicircular or circular cross-section distributes stress more evenly compared to a flat surface, enhancing the pressure resistance performance and preventing structural damage even when cooling high-power devices.
3Loss of energy
If the vapor pipe bending angle is reduced, then the pressure loss coefficient is reduced and cooling performance is enhanced, but the manufacturing complexity increases
Solution Approach 1:
Instead of creating complex angled joints or multiple bends in the vapor pipe, the invention curves the entire heat receiving jacket into a semicircular or circular form. This allows the vapor pipe to be coupled at a natural inclined angle that reduces bending resistance, while the curved jacket itself can be manufactured as a single integrated component, maintaining ease of manufacture.
