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).

Angled turbulator for use in heat exchangers

A plate fin heat exchanger having a plurality of tubes generally perpendicular to and extending through a stack of humped plate fins. The plate fins have a plurality of holes to receive the tubes. These holes are disposed in rows, and are defined by wrinkle free collars surrounding the holes. A number of trapezoidal stiffening beads both short and long are integral to the plate and are disposed between the rows of holes. The rows of holes coincide with rows of arced humps in the plate fins.
