AI Technical Summary
Technical Problem
The existing U-shaped heat exchangers suffer from poor matching between the inlet air profile and the actual velocity of the inlet air due to the influence of the separating plate, leading to high inlet air resistance and increased energy consumption of the fan.
Method used
An asymmetric heat exchanger design is introduced, with specific angles and distances between plates optimized to match the isovelocity surface of the airflow, reducing local flow loss and energy consumption by adapting the profile to the asymmetry of the inlet air.
Benefits of technology
The asymmetric design improves the uniformity of inlet air and reduces resistance, enhancing heat exchange efficiency and reducing fan energy consumption.
