Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If existing immersion cooling solutions are used, then cooling is provided for standard power density servers, but they are inefficient for high-power components and do not support high power density servers
Solution Approach 1:
The cooling system is segmented into dedicated channels with separate inlet and outlet ports, allowing independent optimization of fluid flow paths for different cooling requirements. This segmentation enables efficient heat removal from high-power components while maintaining compatibility with standard power density servers.
Solution Approach 2:
The immersion cooling device implements local quality by providing enhanced cooling capacity specifically at high-power component locations through dedicated channels and ports. The system adapts cooling intensity to local heat generation requirements, using active immersion fluid movers to direct cooling fluid precisely where needed rather than applying uniform cooling throughout.
2Productivity
If immersion cooling fluid is used to cool IT equipment, then heat transfer is achieved, but the system is inefficient for hyperscale deployment
Solution Approach 1:
The system incorporates preliminary action through pre-configured dedicated channels and inlet/outlet ports that are designed beforehand to optimize fluid flow paths. The active immersion fluid movers are positioned and configured in advance to ensure efficient heat transfer from the outset, eliminating the need for trial-and-adjustment deployments in hyperscale environments.
Solution Approach 2:
The immersion cooling device utilizes parameter changes by transitioning between single-phase and two-phase cooling modes through dedicated channels. The system can adjust fluid flow parameters, temperature, and phase state to optimize heat removal effectiveness for different operational conditions and power density requirements, significantly improving overall cooling efficiency.
3Power
If high power density servers are deployed, then computational power is increased, but thermal management becomes more difficult
Solution Approach 1:
The dedicated channels and active immersion fluid movers serve as intermediaries between high-power heat-generating components and the bulk cooling fluid. These intermediary elements efficiently transfer heat from concentrated sources to the cooling medium, managing thermal loads from high power density servers without requiring direct contact between all components and the bulk fluid.
Solution Approach 2:
The system applies pneumatics and hydraulics principles through active immersion fluid movers that use fluid pressure and flow dynamics to enhance heat transfer. The dedicated channels are designed to optimize hydraulic flow characteristics, ensuring efficient heat removal from high-power components through controlled fluid circulation and pressure differentials.
