Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional immersion cooling systems use simple fluid inlet structures, then the device complexity is low, but the fluid distribution is uneven and cooling efficiency is poor
Solution Approach 1:
The piping assembly is segmented into multiple functional components: inflow main pipe, inflow branch pipes, flow inlets, outflow branch pipes, and flow outlets. This segmentation allows each component to perform its specific function optimally, ensuring even fluid distribution to multiple electronic devices while maintaining manageable system complexity through modular design.
Solution Approach 2:
The patent implements local quality by providing multiple flow inlets on different inflow branch pipes at different positions, with each flow inlet sized appropriately for its location. The ring-shaped divider element also creates localized flow zones, ensuring that each region of the cooling tank receives optimized fluid distribution according to its specific cooling requirements.
2Loss of energy
If conventional systems do not segregate fluid zones, then the device complexity is low, but fluid waste occurs and cooling efficiency deteriorates
Solution Approach 1:
The ring-shaped divider element segments the cooling tank interior into distinct fluid zones, separating fresh coolant from warmed coolant. This segmentation prevents mixing of fluid at different temperatures, reduces fluid waste by directing flow paths efficiently, and improves cooling efficiency by ensuring electronic devices are exposed to optimally cooled fluid throughout operation.
3Productivity
If flow inlets are large in size, then fluid flow rate is high, but fluid distribution becomes uneven and cooling efficiency decreases
Solution Approach 1:
Each flow inlet is designed with locally optimized dimensions, sized as a fraction (1/4.5 to 1/6.5) of the inflow branch pipe diameter. This local quality approach ensures that fluid is distributed evenly across multiple flow inlets rather than concentrating in a single large inlet, achieving uniform cooling across all electronic devices while maintaining appropriate flow rates.
4Productivity
If electronic devices are not securely arranged, then the device complexity is low, but space utilization is poor and cooling efficiency is reduced
Solution Approach 1:
The cooling tank interior is segmented into multiple positioning elements that define specific installation surfaces and locations for electronic devices. This segmentation enables precise arrangement and secure positioning of devices, maximizing space utilization while ensuring each device is optimally positioned for cooling efficiency without requiring complex external mounting structures.
