ABSTRACT:
Heat exchanger, particularly for use as a rack evaporator in refrigerators or freezers, including a plurality of stacked shelves and comprising for each shelf: a coil, constituted by a tubular body extending along a path with bends alternated with straight and substantially mutually co-planar portions and by a supporting and/or heat-exchange enhancement structure constituted by metal rods welded to the coil and forming, above the coil, a supporting surface which is substantially parallel to the plane of arrangement of the coil. The coil has, for each shelf, at least one portion that is disconnected from the supporting and/or heat-exchange enhancement structure, and this portion lies substantially parallel to the longer straight portions of the coil and proximate to one side of the shelf. This portion disconnected from the supporting and/or heat-exchange enhancement structure is connected to a tubular portion that mutually connects the coils of two shelves which are not mutually co-planar.
