Engineering Contradiction Analysis
1Temperature
If axial flow fans are used for duct circulation temperature control, then temperature regulation is achieved, but cooling efficiency is low and additional cold air provision is required resulting in high costs
Solution Approach 1:
The patent replaces the traditional mechanical axial flow fan system with a semiconductor cooling sheet that uses the Peltier effect to generate cold air directly. This substitution eliminates the need for mechanical fan-driven air circulation and external cold air provision, achieving both temperature regulation and improved cooling efficiency while reducing operational costs
2Temperature
If axial flow fans are used for temperature control, then temperature regulation is achieved, but additional cold air provision is required resulting in high costs
Solution Approach 1:
The semiconductor cooling sheet replaces the energy-intensive axial flow fan system, eliminating the need for additional cold air provision. The Peltier effect-based cooling generates cold air in-situ, significantly reducing the energy cost and operational expenses associated with temperature control in the battery formation and grading device
3Productivity
If semiconductor cooling sheet is used with cooling surface facing inside the box, then cooling efficiency is improved, but heat dissipation management becomes critical
Solution Approach 1:
The semiconductor cooling sheet is segmented into two distinct functional surfaces: a cooling surface facing inside the box for battery cooling, and a heating surface facing outside the box for heat dissipation. This segmentation allows independent optimization of cooling and heat management, achieving high cooling efficiency while effectively managing heat dissipation through the external heating surface
