Adapter Module Sealing Immersion Cooling Container
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In two-phase immersion cooling systems, dielectric liquid leaks through holes and gaps in the container, making it difficult to maintain airtight connections for power and signal transmission, especially in taller containers, which complicates maintenance and reduces the effectiveness of heat dissipation.
Innovation Solution
A container design with a circuit board that seals openings on the sidewall, incorporating inner and outer connectors connected through the board, eliminating the need for structural through holes and enhancing sealing with additional sealing components like O-rings and conformal coatings to prevent liquid or gas leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If common connectors are installed on holes in the container sidewall for power and signal transmission, then electrical connection between internal and external devices is achieved, but the dielectric liquid or gas leaks through the holes and connectors
Solution Approach 1:
The circuit board acts as an intermediary component that provides both electrical connection and sealing functions. It includes sealing structures that extend into the accommodating space to seal the opening, while also providing mounting surfaces for connectors to establish electrical connections between internal and external devices without compromising the sealing effect.
Solution Approach 2:
The circuit board performs multiple functions simultaneously: it provides electrical connection through connectors, seals the opening in the container sidewall through integrated sealing structures, and maintains the airtight integrity of the container. This multi-functional design eliminates the need for separate sealing components and connectors.
2Reliability
If holes are reduced in quantity and positioned higher on the container, then dielectric liquid leakage is reduced, but power and signal transmission between servers and external devices becomes difficult
Solution Approach 1:
The circuit board with integrated connectors serves as an intermediary that enables electrical connection functionality while maintaining the reduced-hole configuration. The sealing structures on the circuit board ensure that even with fewer holes, the connection capability is preserved without compromising sealing effectiveness.
3Volume of stationary object
If taller containers are used to accommodate servers, then server capacity is increased, but maintenance difficulty increases due to access issues
Solution Approach 1:
The adapter module functions as a segmented, modular component that can be independently installed, accessed, and maintained. This modularity allows maintenance personnel to access and service the connection interface without needing to access the entire tall container, thereby improving maintenance accessibility while preserving container capacity.

AI summary
A container for immersion cooling system includes a plural of container sidewalls, a circuit board, an inner connector, and an outer connector. The plural of container sidewalls form an accommodating space. One of the plural of container sidewalls has an opening. The circuit board is fixed to the one of the plural of container sidewalls and seals the opening. The circuit board has a first surface and a second surface opposite to the first surface. The first surface is exposed to the accommodating space. The inner connector is fixed on the first surface and is located in the accommodating space. The outer connector is fixed on the second surface and is electrically connected to the inner connector through the circuit board. The outer connector is exposed out of the container. Therein, the circuit board, the inner connector, and the outer connector form an adapter module for the container.
