Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If a heat conduction plate with fins is used for heat transmission, then the cooling device can dissipate heat, but heat concentration occurs at the heat source area and heat transmission efficiency is limited
Solution Approach 1:
The patent employs phase transition of the working fluid (evaporation and condensation) to transfer heat from the heat source area. The working fluid evaporates in the evaporation chamber absorbing heat, then condenses in the condensation chamber releasing heat, effectively removing heat concentration at the heat source through phase change rather than conventional conduction.
Solution Approach 2:
The patent uses a liquid-gas working fluid system with defined flow paths (first channel and second channel) to circulate the fluid through the heat source area. The hydraulic flow of the working fluid through the evaporation and condensation chambers enables efficient heat removal, overcoming the limitations of static heat conduction plates.
2Ease of operation
If the working fluid flows through equal-sized holes, then the flow path is simple, but the flow direction is unstable and heat dissipation is ineffective
Solution Approach 1:
The patent employs asymmetric hole dimensions in the separation member, with the first hole having a different size than the second hole. This asymmetry creates a pressure difference that drives the working fluid through a stable, unidirectional flow path (first hole → first channel → second channel → second hole), ensuring reliable flow direction while maintaining operational simplicity.
