Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If air conditioning units are used to cool computer systems, then cooling capacity is provided, but power consumption increases to more than half of total power
Solution Approach 1:
The patent introduces water as an intermediary heat transfer medium between the computer systems and the external environment. Instead of using air conditioning units that directly cool air, the system uses water to absorb heat from computer systems through heat exchangers and transfers this heat to the surrounding water body, thereby reducing power consumption while maintaining cooling capacity.
Solution Approach 2:
The patent employs hydraulic principles by using water flow through heat exchangers to transfer heat from computer systems. The water circulates through the system, absorbing heat thermally and carrying it away, which is a more efficient heat transfer mechanism compared to conventional air-based cooling systems.
2Temperature
If air conditioning units are used to maintain operating temperatures, then suitable ambient conditions are achieved, but cost effectiveness decreases due to high power consumption
Solution Approach 1:
The system leverages the natural cooling capacity of the surrounding water environment to cool the data center. The water body itself serves as the heat sink, eliminating the need for energy-intensive mechanical cooling systems. The system essentially uses the environment's natural resources to provide cooling services.
3Temperature
If conventional cooling systems are used, then cooling is provided, but adaptability to high-density computing systems is insufficient
Solution Approach 1:
The patent changes the fundamental parameter of the cooling medium from air to water, which has superior heat transfer properties and higher heat capacity. This parameter change enables the system to handle higher heat densities, making it adaptable to high-density computing systems that conventional air-based cooling cannot support.
