Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional optical cables fail to effectively facilitate heat dissipation in data centers and optical transceiver modules, despite the generation of high heat during operation.
Innovation Solution
An optical cable design featuring a functional layer with a lower coefficient of friction than the outer sheath, made of materials like aluminum nitride, graphene, or polytetrafluoroethylene, reduces wind resistance and enhances heat dissipation by allowing better airflow through the use of fans.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If conventional outer sheath materials are used, then structural protection is provided, but wind resistance is high and heat dissipation is poor
Solution Approach 1:
The patent applies composite materials by combining the outer sheath (made of fire and moisture resistance material) with a functional layer made of low-friction materials such as aluminum nitride, graphene, polytetrafluoroethylene, or polydimethylsiloxane. This composite structure reduces wind resistance while maintaining protective functions and enabling heat dissipation through the low-friction surface that facilitates airflow.
Solution Approach 2:
The patent changes the surface friction parameter by introducing a functional layer with a coefficient of friction less than that of the outer sheath. This parameter change reduces wind resistance and improves airflow for heat dissipation without compromising the structural integrity provided by the outer sheath.
2Speed
If optical fibers are bundled in an outer sheath, then high-speed optical signal transmission is achieved, but heat accumulation occurs in data centers
Solution Approach 1:
The optical cable structure serves itself for heat dissipation by incorporating a functional layer with low friction coefficient that facilitates airflow. The cable's own surface structure (the functional layer) actively promotes heat removal from the bundled optical fibers without requiring external cooling systems, thus solving the heat accumulation problem while maintaining high-speed transmission capability.
