摘要

The plate has a rectangular form that is formed with heading sections (4, 5) at both faces. Passage openings (2, 3) are provided in the sections to form a passageway channel through a plate package. The radius of each section is equal to half the width of the plate. The centers of the openings lie on the plate`s longitudinal axis. The profile of the sections is equal to the profile of a rectangular part of a heat transmission surface.
