A turbulator (60A-60K) is provided for use in the heat exchange units (34) of heat exchangers. The turbulator (60A-60K) includes a sheet (62A, 62C) of material. The sheet (62A, 62C) includes a plurality of strand-like rows (64A, 64C) of alternating crests (66A, 66C) and valleys (68A, 68C). The crests (66A, 66C) and valleys (68A, 68C) in each row (64A, 64C) are offset with respect to the crests (66A, 66C) and valleys (68A, 68C) in any immediately adjacent row (64A, 64C). Each of the rows (64A, 64C) has an interface with any immediately adjacent row (64A, 64C). The interfaces are perforated so that valleys (68A, 68C) in each row (64A, 64C) are in fluid communication with immediately adjacent crests (66A, 66C) in any immediately adjacent row (64A, 64C) and crests (66A, 66C) in each row (64A, 64C) are in fluid communication with any immediately adjacent valleys (68A, 68C) in any immediately adjacent row (64A, 64C). In some preferred embodiments (60A, 60C, 60D, 60E, 60F, 60H, 60J, 60K), the plurality of rows (64A, 64C) are divided into at least two groups (76A, 76C, 76J; 78A, 78C, 78J) which together define a herringbone pattern of the crests (66A, 66C) and valleys (68A, 68C).
