Abstract: A refrigerator cabinet includes a storage compartment defined by encased walls including inner metal panels and corresponding breaker panels forming a peripheral edge surface surrounding the access opening. A door is hingedly mounted adjacent one edge and includes a resilient sealing gasket to seal the opening. A resilient flap is formed on the breaker panel so that an auxiliary seal is formed separate from the gasket against the liner panel of the door upon closing. An extended dead air space is provided between the flap, gasket and the opposed panels so that heat transfer from the area of the gasket into the compartment is substantially eliminated. The elongated body of the flap is approximately 70 Shore A Durometer hardness of a suitable plastic, such as polyvinylchloride. In the preferred embodiment, the cross-section of the body takes the form of a spike in cross-section with a convergent 5.degree. angle from the base. The flaps extend at included angles of approximately 45.degree. to the panels.

Abstract: A refrigerator has a compartment to be refrigerated and a refrigerant evaporator normally operable at frost producing temperatures to refrigerate the compartment. The evaporator includes an elongated tube to receive refrigerant with an elongated spine fin ribbon of heat exchange material including an elongated base wound in an open spiral about and in intimate heat exchange contact with the tube. A continuous series of fingers project outwardly of the tube along each edge of the base and the distal ends of the fingers are bent to extend generally perpendicular to the root portions of the fingers.

Abstract: A side by side refrigerator has a vertical evaporator formed from an elongated tube wrapped with a ribbon of material having spine fins extending substantially perpendicular from the elongated tube. The elongated tube has elongated straight runs joined by return bent ends to define a vertically extending evaporator having a generally oval spiral or configuration. In one embodiment, the elongated straight runs are spaced from each other throughout the vertical length of the evaporator to provide a space of constant area for air flow.
