摘要

A heat exchanger assembly which comprises spaced tubular header and tank constructions (11) between which a plurality of tubular elements (12) whose open ends are inserted in slots (16) in the header surface (15) or tube member receiving portions. The header surface (15) or tube member receiving portion has a plurality of center elements (20). The apexes of each center portion between the tubular element slots have a flattened area (17) and there are side portions running downward from the center portion apex flats (17) which also are substantially flattened (18).
