Portable device for cold chain storage

A portable device for cold chain storage, the device comprising:

• a container defining therein a storage region, the container including:
• an inner cylinder, the storage region being defined coaxially inwardly of the inner cylinder, the inner cylinder including:
• phase change material disposed therein, the phase change material being in thermal communication with the storage region;
• and
• evaporative coils disposed therein, the evaporative coils being embedded in the phase change material;
• and
• a thermally insulated outer cylinder, an outer wall of the outer cylinder being disposed radially outwardly of an outer wall of the inner cylinder, the inner cylinder being fixedly disposed within the outer cylinder, the inner cylinder and the outer cylinder forming an annulus.

A method of fabricating a portable device for cold chain storage, the method comprising:

• disposing evaporative coils in an inner cylinder of a container;
• embedding the evaporative coils in phase change material;
• defining a storage region of a container coaxially inwardly of the inner cylinder, the phase change material being in thermal communication with the storage region;
• and
• removably disposing a thermally insulated outer cylinder of the container over the inner cylinder such that an outer wall of the outer cylinder is disposed radially outwardly of an outer wall of the inner cylinder, the inner cylinder and the outer cylinder forming an annulus.
