Optical Fiber Coupler Layout for Immersion-Cooled Cabinets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge of maintaining signal transmission quality in optical transmission systems within immersion liquid cooling data centers, particularly as network transmission rates increase, due to coolant interference with light signals.
Innovation Solution
The liquid cooling cabinet apparatus design includes an optical fiber coupler assembly located outside the coolant accommodation space, ensuring that coolant does not contact the optical fiber couplers, thereby preventing signal refraction and maintaining signal quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If optical fiber coupler assembly is placed inside the coolant accommodation space, then cooling coverage is improved, but signal transmission quality deteriorates due to coolant refraction
Solution Approach 1:
The cabinet is divided into two distinct spatial zones: the accommodation space for coolant and electronic devices, and the arrangement area for optical components. This segmentation physically separates the optical fiber coupler assembly from the coolant environment, preventing refraction while maintaining cooling coverage for the electronic devices through the immersion cooling system.
2Reliability
If optical fiber coupler assembly is placed outside the coolant accommodation space, then signal transmission quality is maintained, but device complexity increases due to additional arrangement area requirements
Solution Approach 1:
The arrangement area for the optical fiber coupler assembly is integrated into the cabinet structure rather than being a separate external component. This merging approach maintains signal transmission quality by keeping the optical assembly outside the coolant zone while avoiding the need for additional external structures, thus reducing overall system complexity.
3Loss of energy
If immersion liquid cooling is implemented, then energy efficiency is improved, but coolant interference with optical signal transmission occurs
Solution Approach 1:
The optical fiber coupler assembly is extracted from the coolant environment and placed in the arrangement area outside the accommodation space. This extraction eliminates the harmful refraction effect of coolant on optical signals while preserving the benefits of immersion liquid cooling for the electronic devices through the cooling channels in the cabinet structure.
