Cooler with inclined upper CO.sub.2 cooled surface

A cabinet for containing items to be maintained in a cooled state, said cabinet including a hollow insulated housing having pairs of upstanding side walls and top and bottom walls closing the upper and lower ends of said housing, an inclined baffle mounted within the upper portion of said housing, said inclined baffle being constructed of a material having good heat transfer properties and defining a first closed heat absorbent material receiving chamber thereabove and a second cooled item receiving chamber therebelow within said housing, the lower marginal portion of said baffle terminating substantially against the inner surface of one side wall of said housing, said cabinet including first access means opening into the interior of the first chamber from the exterior of the cabinet and second access means opening into the second items receiving chamber from the exterior of the cabinet, the bottom wall of said housing including upwardly projecting spacer members upon which to support a load of cooled items on said bottom wall, said spacer members being shaped to form, in combination with said load, convection air flow passages between the underside of said load and said bottom wall extending between the lower portion of said one side wall and the lower portion of the side wall opposite said one side wall, said one side wall also including spacer members projecting outwardly therefrom toward the opposite side wall to form, in conjunction with the opposing side of said load, convection airflow passages extending between the lower marginal edge of said baffle and said bottom wall.
