Abstract: A shipping container for cooling a product contained therein is provided. The shipping container includes a frozen material which is mostly insulated from the central chamber of the shipping container. Cool air circulates from the frozen material, to the central chamber of the shipping container. The recirculation of air over the frozen material maintains the central chamber of the shipping container at a predetermined temperature over time. Optionally, a heat exchanger, such as a fan or baffle, can be provided to further enhance the recirculation of the air through the shipping container.
