STORAGE CASE WITH MULTIFUNCTION OF COOLING,FREEZING,HEAT PRESERVATION AND DRYING

摘要

A storage case is designed according to the principle that the coolant can perform heat exchanging. The low temperature due to the evaporating of the coolant is used for cooling and freezing in the storage case. The heat energy released during the course of the heat exchanging is used for heat preservation and drying. Thus, the storage case has multifunction of cooling, freezing, heat preservation and drying.
