A novel extruded aluminum condenser flow tube cross section includes a wider central web flanked by a pair of wider, inboard flow passages with rounded corners integral to the wider web. When inserted into the slot of a highly curved header plate, the wider central web corresponds to a central area of higher bending stresses, which are more strongly resisted. The two wider, inboard flow passages help compensate for the potential flow area removed by the wider central web.
