Solution Overview
Problem
Conventional air cooling methods in data centers are inefficient due to high energy consumption and excessive space requirements, necessitating an effective immersion cooling apparatus for efficient heat dissipation.
Innovation Solution
The immersion cooling apparatus features a chamber with a rack module, a supply part, and a discharge part, allowing a cooling fluid to efficiently flow through slots on the rack module, where cooling targets are mounted, thereby enhancing cooling efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If air cooling method is used, then cooling function is provided, but excessive installation space is occupied and energy consumption is high
Solution Approach 1:
The patent replaces air cooling with liquid immersion cooling, where cooling fluid directly contacts the cooling targets through slots. This hydraulic approach enables more efficient heat transfer in a compact chamber configuration, resolving the contradiction between cooling efficiency and space occupation
Solution Approach 2:
The patent changes the cooling medium from gas (air) to liquid (cooling fluid), fundamentally altering the heat transfer parameter. This phase change from air cooling to liquid immersion enables superior cooling performance in a reduced space footprint
2Temperature
If cooling fluid flows through slots, then cooling efficiency is improved, but fluid stagnation occurs
Solution Approach 1:
The cooling system is segmented into multiple supply holes and discharge holes distributed across the chamber. This segmentation creates multiple flow paths through the slots, preventing fluid stagnation by ensuring continuous circulation throughout the entire cooling area
Solution Approach 2:
Supply holes and discharge holes are positioned at specific locations to create localized flow patterns. The supply holes introduce cooling fluid at certain positions while discharge holes remove it at different positions, ensuring uniform flow distribution and preventing stagnation in any particular region
3Speed
If supply part and discharge part are positioned to maximize flow, then cooling efficiency increases, but bubbles are introduced into the flow path
Solution Approach 1:
The discharge holes are positioned to prevent bubbles from entering the flow path in the first place. By strategically locating discharge holes where they can capture cooling fluid before bubbles form or enter, the system preliminarily prevents the harmful effect of bubble introduction while maintaining high flow speed

Function Achieved in This Case
This solution prevents fluid stagnation, increases cooling fluid flow speed through slots, ensures uniform cooling of multiple targets, and mitigates local fluid level decreases and bubble introduction, resulting in improved cooling performance and reduced energy consumption.
Implementation Method 1
a supply hole portion formed to pass through the supply flow path portion and configured to spray the cooling fluid toward the one side of the slot
Implementation Method 2
a first discharge hole formed to pass through one surface of the discharge flow path portion and configured to suction the cooling fluid discharged from the other side of the slot
