Abstract:
1. A heat exchanger plate, comprising: a corrugated sheet of stiff material configured in a repetitive series of elongated corrugations, each corrugation having a first corrugation segment, a second corrugation segment disposed offset from and extending parallel to the first corrugation segment and an intermediate corrugation segment disposed between and interconnecting the first corrugation segment and the second corrugation segment, the intermediate corrugation segment extending obliquely relative to the first corrugation segment and the second corrugation segment, wherein each one of the intermediate corrugation segments extends rectilinearly along an intermediate ridgeline part in an intermediate corrugation segment direction, wherein a recess is formed into the intermediate corrugation segment at the intermediate ridgeline part and wherein the recess is defined by a flat bottom recess surface, a flat first recess sidewall connected at one end of the flat bottom recess surface and extending therefrom to the intermediate ridgeline part and a flat second recess sidewall connected an opposite end of the flat bottom recess surface and extending therefrom to the intermediate ridgeline part to form a closed recess portion as viewed in side elevation extending along the intermediate corrugation segment direction and an opened recess portion as viewed in side elevation and extending along a transverse direction being perpendicular to the intermediate corrugation segment direction.
