FIELD: heating.
SUBSTANCE: plate of plate heat exchanger includes the main heat exchanging part, distributing-collector parts, holes for inflow and outflow of cooled or heated liquid or steam, corrugations: for location of sealing gaskets, heat exchanging part, near holes, distributing-collector parts, at that the latter are arranged so that to provide for different hydrodynamic resistance at the inlet - with alternating pitch or slope.
EFFECT: balancing of hydrodynamic parameters of elementary volumes of cooled or heated liquid along plate width at their approach from inlet hole through distributor-collector part to the main heat exchanging part and increased efficiency of heat exchange efficiency between two mediums.
