Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If conventional cooling methods are used in servers, then the system structure is simple, but the heat dissipation effect is insufficient due to increasing power consumption
Solution Approach 1:
The patent employs phase transition cooling where the working fluid undergoes phase change from liquid to vapor upon contact with the heat source, absorbing latent heat efficiently. The vaporized fluid is then condensed back to liquid in the condenser, creating a continuous cooling cycle that dramatically improves heat dissipation effectiveness
Solution Approach 2:
The patent utilizes a vacuum pump to create a vacuum environment within the housing, and employs fluid dynamics to circulate the working fluid through atomization, vaporization, and condensation processes. The vacuum environment enhances the evaporation rate and heat transfer efficiency of the working fluid
2Productivity
If the housing is sealed to maintain vacuum, then the heat dissipation efficiency is improved, but the complexity of the vacuum maintenance system increases
Solution Approach 1:
The system is designed to maintain vacuum automatically through the sealed housing structure combined with the vacuum pump. The working fluid cycle itself contributes to vacuum maintenance as the vaporized fluid is continuously removed and condensed, creating a self-sustaining vacuum environment without requiring additional active vacuum maintenance components
3Temperature
If working fluid is continuously sprayed, then heat dissipation performance is optimized, but the consumption of working fluid increases
Solution Approach 1:
The patent implements a working fluid recovery system where the vaporized working fluid is captured, condensed back into liquid form in the condenser, and returned to the atomizer for reuse. This closed-loop system minimizes working fluid loss while maintaining optimal heat dissipation performance
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system achieves rapid and efficient heat dissipation by absorbing latent heat, reducing manufacturing costs, and providing a stable operating environment with flexible fluid control and recycling capabilities.
Implementation Method 1
In a vacuum environment, the temperature of the phase transition point of the working fluid will decrease. When the fine mist is heated, it will directly absorb heat and evaporate into vapor
Implementation Method 2
Since a large amount of fine mist will absorb a large amount of latent heat and vaporize into vapor during phase change, it can quickly absorb a large amount of heat from the surface of the heat source
Implementation Method 3
The vacuum pump is configured to vacuumize the housing... the heated and vaporized vapor will be quickly taken away from the housing through the vacuum pump
Implementation Method 4
the vaporized vapor will be quickly taken away from the housing through the vacuum pump, and then transported to the condenser. The heat of the vapor is released through heat exchange, such that the vapor is condensed back into liquid
Implementation Method 5
The heat of the vapor is released through heat exchange, such that the vapor is condensed back into liquid for repeated recycling
