Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the cooling liquid flow is stopped through the valve when server operation is needed, then the valve control function is achieved, but the server cooling efficiency deteriorates
Solution Approach 1:
The patent extracts the valve control function from the main cooling liquid flow path. A separate control liquid flow path is created with its own valve, allowing the main cooling flow to continue uninterrupted while enabling selective control of a portion of the cooling liquid for operational needs.
Solution Approach 2:
The cooling liquid flow path is segmented into a main cooling liquid flow path and a control liquid flow path. This segmentation allows independent control of different cooling functions, where the main path ensures continuous cooling and the control path provides selective flow control when needed.
2Temperature
If a large liquid tank is used for storing cooling liquid, then the cooling capacity is improved, but the space occupation increases
Solution Approach 1:
The liquid reservoir is designed with movable mounting capability, allowing it to be repositioned or removed as needed. This dynamic design enables flexible space utilization, where the reservoir can be placed in optimal locations for cooling efficiency without permanently occupying fixed large spaces.
Solution Approach 2:
The liquid reservoir serves multiple functions: it stores cooling liquid, acts as a movable cooling unit, and can be repositioned to serve different server configurations. This multi-functionality reduces the need for dedicated large fixed storage spaces.

AI summary
A liquid immersion cooling device includes a mounting frame, a liquid reservoir mounted to the mounting frame, and a cold source distributor mounted on an outer side of the mounting frame. The liquid reservoir is configured to immerse a server in an insulating coolant. The liquid reservoir is movably mounted to the mounting frame. The cold source distributor comprises a telescopic cold source tube and a telescopic heat return tube. An output end of the cold source tube and an output end of the heat return tube are coupled to the liquid reservoir. When the liquid reservoir is pulled out of the mounting frame, the cold source tube and the heat return tube are extended by the liquid reservoir to a predetermined length. When the liquid reservoir is pushed into the mounting frame, the cold source tube and the heat return tube are retracted.
