Design and Optimization Strategies of a High-Performance Vented Box

Area of Science:

• Engineering
• Fluid Dynamics
• Food Science

Background:

• Vented boxes often suffer from chaotic airflow and poor performance due to uneven air distribution.
• Optimizing internal structures is crucial for improving efficiency and extending the shelf life of stored goods.

Purpose of the Study:

• To address airflow heterogeneity and performance issues in vented boxes.
• To develop an efficient and economical method for optimizing vented box internal structures.
• To evenly distribute airflow within the vented box while maintaining constant energy consumption.

Main Methods:

• Sensitivity analysis was conducted on three key structural parameters: number of pipes, holes in the middle pipe, and incremental pipe structure.
• Orthogonal experimental design determined 16 random array sets for parameter testing.
• Commercial software was used for 3D modeling and airflow velocity simulations.

Main Results:

• Airflow velocities and their standard deviations were calculated for each experimental point.
• Range analysis identified optimal combinations of the three structural parameters.
• An efficient and economical optimization method for vented box performance was established.

Conclusions:

• The optimized internal structure design ensures even airflow distribution within the vented box.
• This method provides a practical approach for improving vented box efficiency.
• The findings have significant implications for extending the storage time of fresh food.
