Solution Overview
Problem
Conventional immersion cooling systems face issues with liquid level control, leading to potential leaks and reduced heat dissipation efficiency due to fixed gauge positions that cannot adapt to varying heating component volumes, and require multiple pumps increasing hardware costs.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the liquid level upper limit gauge and lower limit gauge are disposed at fixed positions around the liquid drain opening, then the liquid level control structure is simple, but the liquid level control cannot be flexibly adjusted when heating components with different volumes are placed in the storage tank
Solution Approach 1:
The liquid level upper limit gauge and lower limit gauge are made adjustable rather than fixed, allowing their positions to be dynamically changed according to the volume of heating components. This enables the system to adapt to different liquid level requirements while maintaining a relatively simple overall structure.
Solution Approach 2:
The liquid level control system is designed to serve multiple scenarios by allowing gauge repositioning. The same control structure can handle different heating component volumes by adjusting gauge positions, making the system universal rather than requiring separate control systems for each scenario.
2Reliability
If multiple pumps are used for rehydration and drain functions, then the pump functions are specialized, but the hardware cost and system complexity increase
Solution Approach 1:
A single pump is designed to perform both rehydration and drain functions by switching its operation mode. This multi-functional pump reduces the number of hardware components while maintaining reliable liquid level control through centralized management.
Solution Approach 2:
The rehydration pump and drain pump functions are merged into a single pump unit. This consolidation reduces hardware costs and system complexity while maintaining the necessary functional separation through control logic rather than physical separation.
3Temperature
If the liquid level upper limit gauge and lower limit gauge are positioned at fixed locations, then the installation is simple, but the heat dissipation efficiency decreases when cooling liquid level exceeds the standard due to contact with the condenser
Solution Approach 1:
The liquid level gauges are positioned adjustably rather than at fixed locations, allowing optimization of their positions to prevent cooling liquid from contacting the condenser. This dynamic positioning capability maintains heat dissipation efficiency while preserving installation simplicity through a standardized adjustable mounting mechanism.
