Abstract

The process is used to fabricate a heat-exchanger block of parallel vertical fins or plates (W) at fixed close gap centres. The fins are of aluminium or aluminium alloy, and the process is initiated by the extrusion of an 'I' section with narrow rectangular flanges (20,21). The opposite faces of each flange include an 'L' section tongue (210) and an 'L' section groove (201). The 'I' section is cut into identical lengths and the pieces are then pressed together with webs (W) parallel and all edges in alignment, the tongues on one piece entering the grooves in the preceding piece.
