Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid immersion tanks for electronic equipment face issues with coolant evaporation and level fluctuations, leading to gas mixing in the circulation path, which causes pump faults and increased pressure loss, reducing cooling efficiency.
Innovation Solution
The design incorporates a pocket with a slit structure near the liquid surface to manage coolant overflow and outflow, ensuring the outflow port is positioned to minimize gas entry into the circulation path, maintaining efficient cooling and preventing coolant loss.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the outflow port is positioned near the liquid surface to improve cooling efficiency, then cooling performance is enhanced, but gas mixes into the circulation path causing pump faults and pressure loss
Solution Approach 1:
The tank body is divided into two functional regions: an upper communication region where the outflow port is positioned to access hot coolant near the liquid surface for efficient cooling, and a lower reservoir region that stores coolant and prevents gas from entering the circulation path. This segmentation allows the system to simultaneously achieve high cooling efficiency and reliable gas-free circulation.
2Stability of the object's composition
If the tank capacity is increased to maintain coolant level during evaporation and fluctuations, then coolant level stability is improved, but the tank occupies more space
Solution Approach 1:
The lower reservoir region is pre-configured to store a reserve volume of coolant before operation begins. This preliminary storage capacity allows the system to accommodate coolant level fluctuations due to evaporation or temperature changes without requiring the entire tank to be oversized, thus achieving level stability with minimal additional volume.
3Reliability
If the outflow port is positioned deep in the tank to prevent gas entry, then gas mixing is reduced, but cooling efficiency decreases due to accessing cooler liquid
Solution Approach 1:
The communication region acts as an intermediary zone between the upper hot coolant region and the lower coolant reservoir. The outflow port positioned in this communication region can access hot coolant that rises to the upper region while the lower reservoir prevents gas from reaching the circulation path, thus achieving both efficient cooling and gas prevention simultaneously.
