Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the liquid coolant is used for heat dissipation, then the heat dissipation effect is achieved, but the operating cost increases due to expensive coolant replacement
Solution Approach 1:
The patent changes the physical parameters of the coolant by controlling pressure and temperature to maintain the coolant in a liquid state without requiring replacement. By adjusting the pressure parameter, the boiling point of the coolant is modified, allowing it to remain liquid at higher temperatures and continuously dissipate heat without evaporating and requiring replacement.
Solution Approach 2:
The patent applies preliminary action by pre-cooling the coolant before it enters the heat generation area and pre-heating it in the heat dissipation area. This prepares the coolant optimally for each stage of the cooling cycle, improving heat transfer efficiency and reducing the energy required for the cooling process.
2Temperature
If the pressure in the coolant space is high, then the heat dissipation capability is improved, but the coolant is prone to diffuse outside after vaporization, increasing maintenance cost
Solution Approach 1:
The patent modifies the pressure parameter to create a negative pressure environment in the coolant space. This prevents the coolant from vaporizing and diffusing outside even when heat dissipation capability is enhanced. The pressure control unit maintains stable negative pressure, ensuring the coolant remains contained and eliminating the need for maintenance due to coolant leakage.
Solution Approach 2:
The patent applies beforehand cushioning by establishing a negative pressure environment before any vaporization can occur. This preventive measure ensures that even if the coolant heats up, the negative pressure prevents vapor diffusion outside the system, cushioning against potential reliability issues and maintenance requirements.
3Productivity
If the flow rate of condensate is increased, then the heat dissipation efficiency is improved, but the system complexity increases
Solution Approach 1:
The patent applies dynamics by making the condensate flow rate adjustable rather than fixed. The flow rate can be dynamically optimized based on the actual heat generation conditions, allowing the system to achieve high heat dissipation efficiency when needed while maintaining simplicity through a single adjustable parameter rather than complex multi-component control systems.
