Abstract

Portage storage containers including controlled evaporative cooling systems are described herein. In some embodiments, a portable container including an integral controlled evaporative cooling system includes: a storage region, an evaporative region adjacent to the storage region, a desiccant region adjacent to the outside of the container, and an insulation region positioned between the evaporative region and the desiccant region. A vapor conduit with an attached vapor control unit has a first end within the evaporative region and a second end within the desiccant region. In some embodiments, the controlled evaporative cooling systems are positioned in a radial configuration within the portable container.

Dependent claims

A recharging device for a portable container including an integral controlled evaporative cooling system, comprising:

a frame of a size and shape to removably secure a portable container including an integral controlled evaporative cooling system, wherein the portable container including an integral controlled evaporative cooling system is held in an inverted position;
at least one heating element within the recharging device and positioned adjacent to the exterior of the portable container including an integral controlled evaporative cooling system;
at least one fan affixed to the frame of the recharging device, the fan oriented to direct air against an internal surface of the portable container including an integral controlled evaporative cooling system;
and
a controller operably connected to the at least one heating element and the at least one fan, the controller capable of sending control signals to both the least one heating element and the at least one fan.
