Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If thermally conductive gel is used to dissipate Joule heat from the semiconductor device, then heat dissipation efficiency is improved, but oil component leakage into the optical module occurs
Solution Approach 1:
A sheet member is introduced as an intermediary component between the thermally conductive gel and the optical module. This sheet member allows heat transfer from the gel to the housing while preventing the oil component of the gel from leaking into the optical module, thus resolving the contradiction between heat dissipation efficiency and contamination prevention
Solution Approach 2:
The thermal management system is segmented into distinct functional layers: the thermally conductive gel for heat transfer, the sheet member as a barrier layer, and the housing for heat dissipation. This segmentation allows each component to perform its specific function independently, preventing oil leakage while maintaining heat dissipation efficiency
2Loss of energy
If thermally conductive gel with high coefficient of thermal conductivity is used, then heat transfer from package to housing is improved, but risk of oil component leakage increases
Solution Approach 1:
The sheet member serves as a protective intermediary that enables the use of high-performance thermally conductive gel without compromising optical module integrity. It facilitates efficient heat transfer while blocking the migration of oil components, thus maintaining both heat transfer efficiency and system reliability
