Solution Overview
Problem
In information processing apparatuses, achieving uniform fluid flow rates at multiple outflow ports while maintaining a compact design and reducing pressure loss and power consumption is challenging, especially when the number of outflow ports increases.
Innovation Solution
A manifold with a branch pipe partitioned by a partition wall featuring through-holes with a total opening area greater than the inflow port, and facing portions that direct fluid flow uniformly to each outflow port, reducing pressure loss and ensuring consistent flow rates without enlarging the distribution pipe or increasing pump output.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the number of outflow ports is increased to serve more electronic components, then the cooling coverage is improved, but the uniformity of fluid flow rates at each outflow port deteriorates
Solution Approach 1:
The partition wall is segmented into multiple regions, each containing multiple through-holes. This segmentation allows the inflow to be divided into multiple streams that can be uniformly distributed to multiple outflow ports, ensuring each port receives consistent flow even as the number of ports increases
Solution Approach 2:
The partition wall features local variations in through-hole distribution and facing portion configurations. Each local region is designed with specific through-hole patterns and facing portions tailored to the local flow requirements, ensuring uniform distribution across all outflow ports regardless of the total number of ports
2Loss of energy
If the diameter of the distribution pipe is increased to reduce pressure loss, then the pressure loss is reduced, but the apparatus size increases
Solution Approach 1:
The single large-diameter pipe design is segmented into multiple smaller flow paths through the partition wall with multiple through-holes. This segmentation creates multiple parallel flow channels that collectively provide low resistance to flow while maintaining a compact overall pipe diameter, thus reducing pressure loss without increasing apparatus size
Solution Approach 2:
The partition wall with through-holes acts as an intermediary structure that facilitates smooth flow transition from the inflow port to multiple outflow ports. This intermediary design reduces flow resistance and pressure loss by distributing flow gradually through multiple small openings rather than requiring a single large diameter pipe
3Manufacturing precision
If the pump output is increased to maintain uniform flow rates at multiple outflow ports, then the uniformity of fluid flow rates is improved, but the power consumption increases
Solution Approach 1:
The partition wall segments the inflow into multiple controlled streams through its through-holes and facing portions. This segmentation creates naturally balanced flow paths that deliver uniform flow rates to each outflow port without requiring excessive pump pressure, thus reducing power consumption while maintaining flow uniformity
Solution Approach 2:
The partition wall incorporates local quality variations in through-hole sizes, positions, and facing portion configurations to optimize flow distribution. This localized optimization ensures each outflow port receives appropriate flow without requiring the pump to work harder, thereby maintaining uniform flow rates with lower power consumption

Function Achieved in This Case
The solution ensures uniform fluid flow rates at outflow ports, reduces pressure loss, and maintains a compact apparatus size by dispersing fluid flow through multiple small through-holes, effectively cooling electronic components without increasing the distribution pipe's diameter or pump size, thus minimizing power consumption.
