Refrigerator mullion assembly with hot gas defrost tube

摘要

A mullion assembly includes a mullion rail and hot gas tube for preventing condensation on the mullion of a refrigerator/freezer. The mullion rail is rollformed of steel and includes complementary channels for retaining refrigerator and freezer liners. One of the channels includes an additional formed portion to accept and positively retain a hot gas tube in surface contact with a rear surface of a front wall of the mullion rail to provide acceptable heat transfer from the tube to the steel along the entire length of the mullion rail.
