Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple load devices are immersed in coolant in one tank (conventional liquid-cooled system), then the cooling system can dissipate heat, but the cooling efficiency is relatively low and cannot meet high power density requirements
Solution Approach 1:
The system divides the cooling function into separate modules: a liquid storage vessel containing first cooling medium and multiple heat exchange capsules containing second cooling medium. Each capsule independently cools a load device, enabling modular scaling for high power density applications while maintaining high cooling efficiency through direct heat exchange between the two cooling mediums.
Solution Approach 2:
The heat exchange capsules are nested within the liquid storage vessel. Each capsule contains the second cooling medium and a load device, and is immersed in the first cooling medium. This nested structure enables efficient heat transfer from the load devices through the capsule walls to the first cooling medium, solving the efficiency problem while accommodating high power density through modular arrangement.
2Productivity
If conventional liquid-cooled systems are used, then cooling can be provided, but the usage amount of cooling medium is high and costs increase
Solution Approach 1:
The cooling system is segmented into two distinct cooling mediums with different functions: the first cooling medium in the storage vessel and the second cooling medium in the capsules. This segmentation allows optimized usage of each medium, reducing overall consumption while maintaining high cooling efficiency through their heat exchange interaction.
Solution Approach 2:
The first cooling medium acts as an intermediary that absorbs heat from the second cooling medium in the capsules. This indirect cooling mechanism allows the system to dissipate heat from load devices efficiently while controlling the usage amount of expensive cooling mediums like fluorinated liquids.
