AI Technical Summary
⚠Technical Problem
In existing cooling devices, the flow alignment wall is easily damaged and has high production costs, resulting in insufficient dimensional stability and strength.
⚗Method used
The system employs a breathable flow alignment wall, designed with multiple first and second alignment channels. The first channel has a larger cross-sectional area, while the second channel has a smaller cross-sectional area. It uses polycarbonate (PC) material, combined with a breathable panel and assembly frame, to ensure uniform airflow distribution and stable flow.
🎯Benefits of technology
This achieves high strength and dimensional stability of the flow-aligned wall, avoids airflow blockage, ensures good cooling effect, and reduces production costs.
