ABSTRACT OF THE DISCLOSURE A plate heat exchanger comprises a corrugated heat exchange surface whose corrugations are arranged in rows displaced relative to one another through half the pitch of the corrugation. Fins of each corrugation consist of three portions. Extreme portions are made rectilinear and are dis- posed at the crest and base at an equal angle to the axis of symmetry of the corrugation. Medium portions rigidly connect the fins of the corrugations arranged in adjacent rows. the medium portion of the fins of each corrugation of the heat exchange surface consists of two portions made in the form of arcs of an equal radius and arranged so that the radii of curvature are directed toward one another. A rigid connection of the fins of corrugations is accomplished at mating points of the arc-shaped portions. The proposed invention makes it possible to decrease the volume, mass and the cost of plate heat exchangers.
