Invention Disclosure: Clamshell Refrigeration Cassette

Invention Date: May 21, 2002

Background: The conventional method for producing a refrigeration deck is by fastening individual components to a baseplate. This invention covers a method of surrounding the refrigeration components by a two piece integral molded insulating foam box with a rigid skin. The two piece “clamshell” has molded in features for retaining the various components of the system. It is thought that such a system will reduce assembly time and reduce the number of fasteners needed. In this disclosure, a stirling refrigeration system is shown, but any type of refrigeration system could be used. The clamshell would typically be molded out of plastic.

Description of the invention:

Referring to figure 1.

The refrigeration cassette (1) can be located in the bottom of the cabinet of a piece of Sales and Merchandising equipment.

Figure 2 shows five views of the exterior of the cassette (1).

The cassette consists of a body (2) and a lid (3). On the front surface of the cassette is an opening (4) for ambient air intake. On the back surface of the cassette, there is an opening (5) for waste heat exhaust. On the top surface of the cassette, there is a supply air opening (6) and a return air opening (7). Around the bottom perimeter of the cassette are guide surfaces (8) which interface with guide rails (not shown) located inside of the piece of SME. A handle (9) facilitates handling of the cassette. The Cassette can be carried like a suitcase.

Figure 3 shows a top view of the cassette with the lid removed.

The cassette contains a cold section (20) which is defined by the insulated wall (21) and insulated floor (22) of the cold section. The hot section (23) of the cassette is defined by the the insulated wall (21), the exterior wall (24) and the non-insulated fl...
