Solution Overview
Problem
Conventional heat dissipation solutions in server racks occupy valuable space, compromising computational hardware density and are inefficient in managing heat within confined spaces, often requiring multiple cooling structures across multiple rack units.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If conventional coolant systems are installed in server racks, then heat dissipation is achieved, but valuable space is occupied compromising computational hardware density
Solution Approach 1:
The patent routes coolant manifolds through the vertical edge portions of the rack structure rather than installing cooling components within the horizontal rack units. This dimensional shift allows coolant distribution to occur in the vertical dimension, preserving horizontal space for computational hardware while achieving effective heat dissipation through front and rear edge manifolds that serve multiple rack units simultaneously.
2Temperature
If conventional coolant systems are installed to dissipate heat, then cooling capacity is provided, but multiple rack units are required increasing device complexity
Solution Approach 1:
The edge-mounted coolant manifolds serve multiple rack units simultaneously, with a single manifold structure providing cooling capacity across several vertical rack units. The front edge manifold distributes coolant to multiple units through vertical routing, and the rear edge manifold collects heated coolant from multiple units, eliminating the need for separate cooling structures in each rack unit and reducing overall system complexity.
3Volume of moving object
If coolant manifolds are routed through edge portions, then space utilization is optimized, but routing complexity increases
Solution Approach 1:
The patent combines the coolant distribution and collection functions into integrated manifold structures mounted on the rack's edge portions. The front edge manifold merges multiple coolant distribution lines into a single vertical routing path, and the rear edge manifold merges multiple coolant collection lines similarly. This consolidation reduces the number of separate routing paths needed compared to individual unit cooling, simplifying the overall routing configuration while maximizing space utilization.
