Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If a water cooling system is used to cool high heat-flow density servers, then heat dissipation efficiency is improved (3500 times higher than air cooling), but the risk of refrigerant leakage and circuit board short circuit increases due to water containing impurities
Solution Approach 1:
The patent uses a sealed shell containing water cooling refrigerant that is designed to be non-reusable once leaked. The system accepts that leakage will occur and designs the sealed shell to contain the refrigerant, preventing it from contacting the circuit board and causing short circuits. This approach prioritizes heat dissipation efficiency while managing the reliability risk through containment rather than prevention of leakage.
2Loss of energy
If an insulating refrigerant is used for phase change heat exchange cooling, then cooling effect is improved (latent heat of vaporization is many times greater than specific heat), but sealing requirements increase and maintenance complexity increases due to refrigerant leakage risk
Solution Approach 1:
The patent employs a sealed shell containing insulating refrigerant for phase change cooling. The sealed shell is designed as a disposable component that contains the refrigerant and prevents leakage. When leakage occurs or maintenance is needed, the entire sealed shell is replaced rather than attempting to repair the sealing system, thereby simplifying maintenance while maintaining the high cooling effect of phase change heat exchange.
Solution Approach 2:
The cooling system is divided into a sealed shell containing the refrigerant and the server components. This segmentation isolates the refrigerant within the sealed shell, preventing direct contact with the server and eliminating the need for complex sealing around the server components. The sealed shell acts as a self-contained unit that can be easily replaced if needed.
3Ease of operation
If manual handling of heating elements in cooling liquid is performed, then maintenance flexibility is improved, but labor intensity increases and safety risks increase due to refrigerant contact
Solution Approach 1:
The patent implements an automated mechanical arm system that handles heating elements in the cooling liquid without human intervention. The mechanical arm is equipped with sensors and control systems that enable it to autonomously locate, grasp, and manipulate the heating elements, thereby eliminating the need for manual handling and the associated safety risks of refrigerant contact while maintaining maintenance flexibility.
4Loss of energy
If a sealed shell with refrigerant is used for cooling, then heat dissipation performance is improved, but the complexity of maintaining and repairing the system increases
Solution Approach 1:
The cooling system is segmented into a sealed shell containing the refrigerant and the server components. This segmentation allows the sealed shell to be treated as a modular unit that can be easily replaced without disassembling or repairing the internal refrigerant system. The sealed shell acts as a self-contained module that maintains heat dissipation performance while simplifying maintenance through modular replacement.
Solution Approach 2:
The sealed shell is designed as a disposable component that is replaced rather than repaired when maintenance is needed. This approach eliminates the complexity of repairing the sealed shell and its refrigerant system, as the entire unit is simply replaced with a new one, thereby maintaining high heat dissipation performance while significantly simplifying maintenance procedures.

Implementation Method 1
a condensation module, located in the shell, and accommodated therein with a refrigerating material for cooling the gasified cooling liquid
Implementation Method 2
the latent heat of vaporization is taken away from the heat when the refrigerant is boiling. The latent heat of vaporization when the refrigerant boils is utilized to transfer heat
Implementation Method 3
