摘要

A heat exchanger in which a header and tank construction comprises separate header (11) and tank portions (12) which are used in combination to form a heat exchanger unit. End caps (15) for the header and tank construction and baffles (26,27) to form partitions or chambers within the header and tank construction are inserted in grooves (28,29,30,31,32) formed in the separate header (11) and/or tank portion(s) (12). The heat exchanger assembly comprises spaced combined header and tank constructions between which extend a plurality of tubes (17) which are inserted in slots (16) in the header portions (11). An area of the header portion (11) can have a plurality of center portions and slots (16) between adjacent center portions for the tubular elements (17). The apexes (42) of each center portion between the tubular element slots (17) have a flattened area and there are side portions (43) running downward from the center portion apex flats (42) which also are substantially flattened.
