Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single large tank is used for immersion cooling, then the system structure is simple, but vapor distribution becomes uneven and condensation efficiency deteriorates
Solution Approach 1:
The patent divides the single large tank into multiple separate tank bodies (first tank body, second tank body, etc.), each containing its own heating unit and heat dissipation medium. This segmentation creates independent vapor generation zones, ensuring uniform vapor distribution throughout the cooling system and improving condensation efficiency on the condenser surface.
2Productivity
If all heating units are operated simultaneously for maximum cooling capacity, then cooling performance is optimized, but maintenance requires shutting down the entire system causing loss of time
Solution Approach 1:
Each tank body is equipped with independent valve units (first valve unit and second valve unit) that allow individual isolation and maintenance of specific heating units without affecting others. The maintenance flow time is calculated based on individual tank body parameters, enabling targeted maintenance while keeping other sections operational.
Solution Approach 2:
The system dynamically adjusts operational status of individual tank bodies through the valve units, allowing flexible switching between operational and maintenance states for each segment independently, thus optimizing both cooling capacity and maintenance efficiency.
3Device complexity
If the system is designed as a single integrated unit, then device complexity is low, but pressure buildup risks tank rupture
Solution Approach 1:
The system separates the integrated tank into multiple independent tank bodies, each with its own pressure management through valve units. This segmentation distributes and isolates pressure risks, preventing localized pressure buildup from compromising the entire system and eliminating the need for complex pressure relief mechanisms in a single large tank.
4Ease of operation
If vapor spaces are connected to the external environment for pressure equalization, then pressure management is simplified, but heat dissipation medium is lost increasing cost
Solution Approach 1:
The valve units act as intermediary components between the vapor spaces and the external environment, controlling vapor flow and pressure equalization while preventing uncontrolled escape of heat dissipation medium. This intermediary mechanism simplifies pressure management while minimizing substance loss.
