<p>A heat transfer element assembly (30) is comprised of a plurality of first and second profiled heat transfer plates (32,34) which incorporate a series of first and second single-lobed outwardly protruding notches (40,50) which extend obliquely relative to the general direction of fluid flow through the assembled plates. The first and second profiled heat transfer plates (32,34) are assembled alternately in juxtaposed relationship in a stacked array with the obliquely extending spacing notches (40,50) of neighboring plates crossing each other. The first and second profiled heat transfer plates are provided with a plurality of first single-lobed notches (40) protruding outwardly from one side of the plate and a plurality of second single-lobed notches (50) protruding outwardly from the other side of the plate. The first and second single-lobed notches are arranged in staggered relationship with one or more second single-lobed notches (50) disposed between each pair of first single-lobed notches (40).</p> |
