Refrigeration cabinet construction

摘要

A refrigerated appliance cabinet for a chest-type freezer is formed from prefinished materials. The side walls of the shell and the liner are formed as a single piece, with the evaporator and condenser coils assembled before bending and after a thermal mastic has been applied to the places where the tubing contacts the sheet metal. The tubing is held in place by a hot melt adhesive. After the side walls are folded, bottom walls are attached mechanically and the liner inserted into the shell, with the space at the top being covered by a breaker strip arranged with the top edge of the liner and shell to provide air venting during foaming so that the foam can expand directly into contact with the underside of the breaker strip and adhesively hold it in place. The compressor compartment is attached mechanically to the shell around an opening, and the weight of the machinery is supported by that connection and the surrounding foam.
