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