ABSTRACT:
In a refrigerator door mounting frame, the use of a thermal barrier between the cold portion and the warm portion of the frame in combination with a divided thermal conduction path extending from an intermediate portion into the cold portion. The divided path comprises a thick load-bearing section through which conduction is impeded by the thermal barrier, in parallel with a thinner sealing face plate section exposed to the air outside the refrigerator and electrically heated to prevent condensation. In this way condensation is prevented and the heat load on the refrigerator is minimized.
