Abstract

The present application provides a cooler. The cooler may include an outer frame, a product space within the outer frame, and a number of shelf assemblies positioned within the product space. The shelf assemblies may include an evaporator and a phase change material therein.

First claim

We claim:

1. A cooler, comprising:
an outer frame;
a product space within the outer frame;
a plurality of shelf assemblies positioned within the product space;
the plurality of shelf assemblies comprising an evaporator and a phase change material therein;
the plurality of shelf assemblies dividing the product space into a plurality of shelf chambers each having the evaporator and the phase change material on a top and a bottom thereof;
the plurality o shelf assemblies comprising a top surface and a bottom surface;
the phase change material being disposed within a plurality of phase change material cells position on top of and below the evaporator coil in the plurality of shelf assemblies between the top surface and the bottom surface of the plurality of shelf assemblies;
the plurality of shelf assemblies comprising one or more layers of insulation position about the plurality of phase change material cells between the top surface and the bottom surface e o the plurality of shelf assemblies;
the plurality of shelf assemblies comprising one or more spring loaded bolts positioned between the top surface and the bottom surface of the plurality of shelf assemblies; and
the one or more spring load bolts being configured to accommodate thermal expansion and contraction of the plurality of phase change material cells.

2. The cooler of claim 1 , wherein the outer frame comprises a hexagon shape.

3. The cooler of claim 1 , wherein the outer frame comprises six or more sides.

4. The cooler of claim 1 , wherein the outer frame comprises a door with a transparent panel.

5. The cooler of claim 1 , further comprising a refrigeration system in communication with the evaporator.

6. The cooler of claim 1 , wherein the phase change material comprises water.

7. The cooler of claim 1 , wherein the plurality of shelf assemblies comprises a top shelf assembly with a top evaporator coil positioned about a top of the product space.

8. The cooler of claim 1 , wherein the plurality of shelf chambers comprises a plurality of self-contained shelf chambers.

9. The cooler of claim 1 , further comprising a plurality of products positioned in a zig-zag arrangement.

10. The cooler of claim 1 , further comprising a plurality of products positioned in a uniform row and column arrangement.

11. The cooler of claim 1 , wherein the outer frame comprises a D-shape.

12. The cooler of claim 1 , further comprising a Seebeck indicator positioned about the outer frame and the product space.

13. The cooler of claim 1 , wherein the plurality of phase change material cells comprise an open structure foam material soaked with water.
