Abstract

A heat exchange unit mainly for a refrigerator comprises a sheet of metal which has been perforated by punching using a roller having a plurality of teeth which causes material to be displaced to form a rectangular perforation and the displaced material to be bent to one side of the sheet around the perforation. The roller forms a series of lines of perforations 2 between which is left an unperforated strip 3 having indentations 4 to which is spot welded the condenser tubing 5 in the form of a serpentine.
