Abstract
A portable container includes a cooling unit with a vessel and a base. A thermal cover can cover the vessel to insulate a chamber in the vessel that holds one or more goods. The vessel has a cavity filled with a phase change material or thermal mass, and thermally conductive plate(s) extending within the cavity and in thermal contact with the phase change material or thermal mass. The base is attached to the vessel and houses thermoelectric module(s) in thermal communication with the thermally conductive plate(s), a heat sink in thermal contact with the thermoelectric module(s), a fan operable to flow the air past the heat sink, and circuitry that operates the thermoelectric module(s) and fan. The thermoelectric modules are operable to charge the phase change material or thermal mass, so the charged phase change material or thermal mass (once charged) passively cools or heats the chamber.
