Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current liquid-cooling type double-sided coolers face limitations in cooling efficiency due to temperature deviations, pressure losses, and increased risk of blockages in the bending process, which affect the performance and reliability of power modules in eco-friendly vehicles.
Innovation Solution
The design incorporates a dual cooling system with separate upper and lower cooling portions connected via communication holes, featuring edge portions and protrusions for secure coupling and sealing, reducing pressure loss and enhancing cooling efficiency by ensuring a stable flow path and preventing blockages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the number of cooling pins is increased to enhance cooling efficiency, then cooling performance is improved, but the flow path size is reduced and the risk of blockage is increased
Solution Approach 1:
The cooling system is divided into multiple independent flow paths (first cooling liquid path and second cooling liquid path) that are connected through communication holes. This segmentation allows cooling pins to be distributed across separate paths, preventing any single path from becoming overly congested while maintaining high cooling efficiency through multiple parallel cooling channels.
Solution Approach 2:
Communication holes serve as intermediary connection points between the first and second cooling liquid paths. These intermediaries allow cooling liquid to flow between paths, balancing the flow distribution and preventing blockages by providing alternative routes when one path becomes congested with multiple cooling pins.
2Ease of operation
If a bending process is used to form cooling tubes, then the cooler can contact upper and lower surfaces of the power module, but pressure loss increases and the flow path may be narrowed or blocked
Solution Approach 1:
Instead of using a single bent tube, the cooling system is segmented into separate cooling portions (first cooling portion and second cooling portion) with distinct flow paths. This eliminates the need for complex bending to achieve contact with both upper and lower surfaces, as each portion can be independently positioned and connected through communication holes, thereby reducing pressure loss.
3Device complexity
If the same flow path formation is used in cooling and non-cooling periods, then structural simplicity is maintained, but unnecessary pressure loss occurs in the non-cooling period
Solution Approach 1:
The cooling portions are designed to be dynamically positionable at different locations. In the cooling period, they are positioned to contact the power module surfaces; in the non-cooling period, they can be repositioned to optimize flow path alignment and minimize pressure loss. The communication holes enable flexible connection between portions regardless of their positions.
