  • Foam-insulated side-by-side refrigerator

    Abstract: In a side by side refrigerator-freezer appliance, thermal leakage between the compartments is reduced by forming the liners separately for each compartment, but without the partition wall. Adjacent edges of the liners are spaced apart and desirably out-turned to form a truncated V groove. A partition wall is separately formed and foam insulated; edges of the partition are upset to form a tongue slidable along the groove whereby the partition is retained in position.
