Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fully immersed liquid cooling technologies for servers in data centers face issues such as excessive cooling liquid consumption, poor immersion effect due to unoccupied slots, cumbersome operation, and high maintenance costs due to the need for lifting and draining servers, which is time-consuming and resource-intensive.
Innovation Solution
A liquid cooling server cabinet with pluggable assemblies and independent cooling units for each server, allowing for easy plug-in and plug-out operation, reducing the need for full immersion and minimizing liquid consumption, and enabling efficient maintenance without shutting down the entire system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If fully immersed liquid cooling technology is used with medium to large horizontal cabinets, then cooling effectiveness is improved, but operation and maintenance costs increase due to the need for professional lifting tools and draining procedures
Solution Approach 1:
The patent divides the server cabinet into multiple independent pluggable assemblies, each capable of being removed and replaced individually. This segmentation allows maintenance of single servers without affecting others, eliminating the need for full system draining and professional lifting tools, thus reducing operation and maintenance costs while maintaining cooling effectiveness.
Solution Approach 2:
The patent introduces a dynamic pluggable assembly design that allows servers to be easily inserted and removed from the cabinet. This dynamic structure replaces static fully-immersed cooling with a flexible system where cooling connections are established and broken easily, enabling simple maintenance operations without specialized equipment.
2Ease of repair
If professional lifting tools and draining procedures are used for server maintenance, then server replacement is achieved, but time consumption increases
Solution Approach 1:
By dividing the cabinet into independent pluggable assemblies, the patent enables individual server replacement without draining the entire system. This segmentation reduces maintenance time significantly as only the specific server needing replacement is removed, not the entire cooling system.
Solution Approach 2:
The pluggable assemblies are pre-designed with integrated cooling connections and mounting structures. This preliminary design allows servers to be quickly replaced by simply unplugging and replugging assemblies, eliminating time-consuming draining and lifting procedures.
3Temperature
If medium to large horizontal cabinets are used for fully immersed cooling, then cooling capacity is improved, but device complexity increases
Solution Approach 1:
The patent simplifies cabinet structure by segmenting it into standardized pluggable assemblies. This modular approach reduces overall device complexity compared to large horizontal cabinets, while maintaining cooling capacity through multiple independent units that can be configured flexibly.
Solution Approach 2:
The patent transitions from horizontal cabinet configuration to vertical stacking of pluggable assemblies. This dimensional change simplifies the overall structure while maintaining cooling capacity, and enables easier installation and maintenance operations.
