insulated delivery bag 3d model

Thermal Performance Simulation of a Standard Insulated Delivery Bag for Cold Storage Applications Using ANSYS Objective: The objective of this study is to evaluate the thermal performance of a standard insulated delivery bag used for transporting frozen products such as ice cream under summer ambient conditions. Bag Configuration: The delivery bag consists of an inner air cavity of 400 mm × 400 mm × 400 mm, surrounded by a 25 mm thick polyurethane foam insulation layer and a 1 mm thick outer fabric layer. Internal Dimensions: 400 mm × 400 mm × 400 mm Insulation Thickness: 25 mm Polyurethane Foam Outer Fabric Thickness: 1 mm Overall External Dimensions: 452 mm × 452 mm × 452 mm Initial Internal Temperature: −18°C Ambient Temperature: 35°C Temperature Difference: 53°C Material Properties – Polyurethane Foam: Density = 35 kg/m³ Thermal Conductivity = 0.025 W/m·K Specific Heat Capacity = 1400 J/kg·K Material Properties – Air: Density = 1.225 kg/m³ Thermal Conducti creat thermal
