Abstract
A refrigerator is provided having an outer housing and an inner housing which is at a distance from the outer housing and is surrounded by the latter, with the hollow space produced between the outer housing and the inner housing being filled with foam for insulation purposes. An inner chamber is surrounded by the inner housing and is cooled by the circulation of cooling air supplied to the inner chamber by means of a cooling-air duct and is arranged between the outer housing and the inner housing. A method is provided for forming the cooling-air duct from a shaped part that has insulating material and a closed rear-wall element and rests on an outer face of the inner housing.
