Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fully immersed liquid cooling technologies for servers in large horizontal cabinets face issues such as excessive cooling liquid consumption, poor immersion effect due to unoccupied slots, cumbersome operation, and high maintenance costs due to time-consuming draining and lifting processes.
Innovation Solution
A liquid cooling server cabinet with pluggable assemblies and independent cooling units for single-node servers, allowing easy plug-in and plug-out installation, reducing the need for full immersion and minimizing liquid consumption, and enabling efficient, independent cooling without affecting other servers during maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If fully immersed liquid cooling technology is used in medium to large horizontal cabinets, then server cooling effectiveness is improved, but cooling liquid consumption increases excessively
Solution Approach 1:
The cabinet is divided into multiple independent cooling zones, each with its own liquid cooling unit and cooling liquid supply system. This segmentation allows each zone to be cooled independently, reducing the total cooling liquid volume needed compared to a single large immersed cooling system.
Solution Approach 2:
Different cooling methods are applied to different parts of the cabinet: fully immersed cooling is used for certain zones while other zones use alternative cooling approaches. This local differentiation optimizes cooling effectiveness while minimizing overall cooling liquid consumption.
2Temperature
If fully immersed liquid cooling is implemented, then server thermal management is improved, but maintenance operation complexity increases due to draining and lifting requirements
Solution Approach 1:
The cabinet is divided into multiple independent cooling zones with separate access mechanisms. This allows maintenance personnel to access and maintain servers in specific zones without needing to drain the entire cooling system or lift heavy servers, significantly simplifying maintenance operations.
Solution Approach 2:
Servers can be extracted from their cooling environments through dedicated access channels and mechanisms, allowing maintenance personnel to remove servers for repair without requiring complex draining and lifting operations, thus improving ease of maintenance.
3Power
If medium to large horizontal cabinets are used for immersion cooling, then server cooling capacity is improved, but device complexity increases
Solution Approach 1:
The complex cooling system is segmented into multiple independent modules, each with its own cooling liquid supply and circulation system. This modular approach reduces the complexity of any single component while maintaining the overall cooling capacity of the entire cabinet.
