Insulated cabinet

Refrigerated cabinet apparatus, comprising:

• an enclosure defining an insulated region for receiving goods to be cooled;
• means within said region defining a goods receiving support spaced apart from the bottom of said enclosure so as to define an air circulation passage therealong between said support and said enclosure;
• means associated with said enclosure for defining a cavity separate from said insulated region;
• first air flow means communicating between an upper location of said insulated region and an upper portion of said cavity;
• second air flow means communicating between a lower portion of said cavity and said air circulation passage;
• cooling means in the upper portion of said cavity to cool air therein, so that the cooled air moves downwardly along a path within said cavity and flows through said second air flow means to enter said air circulation passage in said goods receiving region;
• and
• means defining a vertical region of diminishing effective aperture on said path between said upper location and said lower portion of the cavity, so that the relatively dense air cooled by said cooling means moves downwardly through said vertical region of diminishing aperture and thereby moves at an increasing velocity before reaching said lower portion, so as to increase the velocity of cooled air moving by convection to said goods receiving region.
