Abstract

See full text

A heat exchanger plate includes a corrugated sheet of stiff material configured in a repetitive series of elongated corrugations. Each corrugation has a first corrugation segment, a second corrugation segment disposed offset from and extending parallel to the first corrugation segment and an intermediate corrugation segment. The first and second corrugation segments extend vertically. The intermediate corrugation segment is disposed between and interconnects the first corrugation segment and the second corrugation segment and extends obliquely relative to the first corrugation segment and the second corrugation segment to form a continuous, uninterrupted offset corrugation. A plurality of the heat exchanger plates are connected together to form a fill pack.
