Immersion Cooling Seal Lid for Replaceable Optical Fibers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing immersion cooling apparatuses for optoelectronic processing devices face challenges in maintaining a hermetic seal to prevent fluid coolant leakage and in easily replacing signal transmission lines, such as optical fibers, due to complex sealing structures.
Innovation Solution
A sealing structure for an immersion cooling apparatus comprising a first lid portion, a second lid portion, and a sealing component with first and second sealing parts, which are detachably connected to form a hermetic sealing lid that covers the opening of the tank body, allowing for easy replacement of optical fibers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a hermetic sealing structure is used to prevent fluid coolant leakage, then sealing reliability is improved, but the complexity of replacing signal transmission lines increases
Solution Approach 1:
The sealing lid is divided into a first lid portion and a second lid portion that can be detachably connected. The optical fibers are routed through the sealing component between these two detachable portions, allowing the lid to be separated for fiber replacement while maintaining hermetic sealing when assembled. This segmentation enables independent access to optical fibers without compromising the overall sealing integrity.
2Reliability
If optical fibers are sealed within the hermetic structure, then sealing reliability is improved, but the ease of replacing signal transmission lines deteriorates
Solution Approach 1:
The sealing component acts as an intermediary structure that guides and protects optical fibers while allowing controlled access. The detachable connection between the first lid portion and second lid portion provides a controlled access point for fiber replacement, and the sealing component maintains the hermetic seal around the fibers during this process. This intermediary structure enables fiber replacement without requiring complete disassembly or compromising sealing integrity.
3Ease of operation
If a detachable lid structure is used to facilitate replacement of signal transmission lines, then ease of operation is improved, but sealing reliability may deteriorate
Solution Approach 1:
The sealing component is pre-configured with sealing surfaces on both the first lid portion and second lid portion. These sealing surfaces are designed to mate together when the lid portions are assembled, ensuring hermetic sealing is automatically restored after detachment and reassembly. The preliminary preparation of complementary sealing surfaces guarantees sealing reliability is maintained through the detachable connection mechanism.

AI summary
A sealing structure for an immersion cooling apparatus housing and cooling an optoelectronic processing device includes a first lid portion, a second lid portion detachably connected to the first lid portion, and a sealing component. The sealing component includes a first sealing part disposed on the first lid portion and a second sealing part disposed on the second lid portion. The first lid portion, the second lid portion, and the sealing component jointly define a sealing lid hermetically covering an opening portion of a tank body included in the immersion cooling apparatus. Part of optical fibers included in the optoelectronic processing device are sandwiched between and encompassed by the first sealing part and the second sealing part.
