Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If coolant flows through channels adjacent to partition walls, then heat is removed from the heat generating member, but the coolant temperature rises due to heat conduction from the partition walls
Solution Approach 1:
A third channel is introduced as an intermediary coolant passage between the first and second channels. This third channel carries coolant that has not yet been heated by the heat generating member, and it flows adjacent to the partition wall to prevent heat conduction from the partition wall to the cooled coolant. The third channel acts as a thermal barrier and coolant refresh source, maintaining lower temperatures in the cooling system.
Solution Approach 2:
The coolant flow path is segmented into three separate channels: a first channel for coolant after heat absorption, a second channel for coolant before heat absorption, and a third channel specifically positioned adjacent to the partition wall. This segmentation allows independent control of coolant flow in each channel, enabling the third channel to specifically address the heat conduction issue from the partition wall without affecting the overall cooling function.
2Ease of operation
If partition walls are used to separate coolant channels, then coolant flow is controlled, but heat conduction through the partition wall causes downstream temperature rise
Solution Approach 1:
The third channel serves as a mediator between the partition wall and the cooled coolant. By positioning this channel adjacent to the partition wall and filling it with relatively cool coolant, the system prevents direct heat conduction from the partition wall to the coolant that needs to be cooled. The third channel effectively decouples the thermal interaction between the partition wall and the primary cooling channels.
Solution Approach 2:
The invention changes the thermal parameter distribution by introducing a third coolant channel with different thermal characteristics. The coolant in the third channel has lower temperature and different flow characteristics compared to the first and second channels. This parameter change (temperature, flow rate) in the third channel specifically addresses the heat conduction issue while maintaining the structural integrity and flow control benefits of the partition wall.
