Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If coil heat exchangers, finned tube heat exchangers, or plate heat exchangers are used in immersion cooling systems, then condensation performance is acceptable, but pressure loss of cooling water is relatively large and cooling energy consumption increases
Solution Approach 1:
The heat exchanger is divided into multiple independent heat exchange units arranged in parallel. Each unit consists of a transparent heat exchange tube with internal flow channels, allowing cooling water to flow through multiple separate paths simultaneously. This segmentation reduces the pressure loss in each individual channel while maintaining overall heat exchange capacity, directly addressing the contradiction between acceptable condensation performance and reduced pressure loss/energy consumption
2Use of energy by stationary object
If commonly used condensation heat exchangers are used, then condensation performance is acceptable, but pumps with relatively large horsepower are needed resulting in large cooling energy consumption
Solution Approach 1:
The cooling water flow system is segmented into multiple parallel channels, each with its own flow path through the heat exchange tubes. This distribution of flow across multiple low-resistance paths reduces the total pumping power required, directly addressing the contradiction between acceptable condensation performance and reduced pump horsepower/energy consumption
Solution Approach 2:
The patent changes the flow regime parameters by using transparent heat exchange tubes with specific internal structures that optimize fluid flow characteristics. The tube design promotes efficient heat transfer while minimizing flow resistance, allowing the system to achieve acceptable condensation performance with lower pumping power requirements
3Reliability
If dense pipeline is used to achieve high heat conduction, then heat exchange performance is improved, but device complexity and manufacturing difficulty increase
Solution Approach 1:
Instead of using a single dense pipeline system, the patent segments the heat exchange function into multiple separate transparent tubes with internal flow channels. Each tube independently performs heat exchange, achieving high overall heat conduction performance without the complexity of a dense integrated pipeline network, directly addressing the contradiction between heat exchange performance and device complexity
