SYSTEM AND METHOD FOR TEMPERATURE MODULATION USING PHASE CHANGE MATERIAL IN A SPECIAL HEAT EXCHANGER

摘要

A system for improved heat exchange mechanism maintaining eutectic cold plate at a temperature below the freezing point for prolonged time interval and/or in various environmental conditions during delivery and a method thereof. Invention provides a method and a system for providing improved heat transfer based eutectic cold plate refrigeration system or heat exchange system which either precools the products and circulates cool air on the product keeping them at a desired storage temperature for prolonged time interval during delivery, thus providing an improvised PCM heat exchanger with specific combination of tube spacing, extended surfaces (fins) and refrigeration circuit that enhances the heat transfer capability for freezing of PCM, an air sparger at the bottom of said chamber to create turbulence during discharge rate of heat from the eutectic plate assembly to the stored product inside insulated container such that heat is distributed effectively through the phase change material.
