Analysis And Simulation For Insulating Package Based On ANSYS

Insulating packaging is used in a variety of applications to protect temperature- sensitive products from thermal damage. A temperature-sensitive product is one whose characteristics are easily changed as the ambient temperature changes.Several factors affect the performance of insulating packages. These factors include the heat transfer through the packaging material, the geometry of the package and the contact resistance between the coolant and the package, ambient temperature. In this research, a comprehensive computer model, including all of these factors, was developed to effectively design and analyze the performance of the insulating package.Comparing computer model simulation results from various models with experimental data, one spherical shell model (with the inside volume of the spherical shell equaling the inside volume of the rectangular container and the outside volume of the spherical shell equaling the outside volume of the rectangular container) is identified most suitable for use in the following research. The innovational work in this research work is to give the applicable scope of the spherical shell model, which is the rate of biggest and smallest side can not be more than 2.This optimized design on the spherical shell model can be then transformed to rectangular configurations by using the same rule used for transforming rectangular configurations to the spherical shell configuration.The spherical shell model offers a unique basis for packaging analysis and design due to the closed-form solutions of heat transfer through this spherical shell configuration. Based on this model, the insulating packaging solution can be achieved by using'minimum packaging cost'as an optimization target.The comparison of results predicted from the computer model with benchmark experimental data shows satisfactory agreement in terms of package duration. As a result, this research offers not only an effective computer model for insulating package system, but also a unique transformation between the spherical and rectangular configurations, providing a straightforward tool, validated by benchmark experiments, for making insulating package design for the packaging industry.
