FIELD: heat engineering.
SUBSTANCE: invention relates to the field of heat engineering and can be used in plate heat exchangers. A heat transfer plate (2a) comprising a first end portion (8), a second end portion (16) and a central portion (24) located in this sequence along the longitudinal central axis (L). The central portion (24) contains a heat transfer region (26) where the support ridges (60) and support valleys (62) extend longitudinally parallel to the longitudinal central axis (L). Support ridges (60) and valleys (62) are arranged in alternating order along or at some distance = x separated from each other imaginary longitudinal straight lines (64) that run parallel to the longitudinal central axis (L) and along a number of separated from each other imaginary transverse straight lines (66) that run perpendicular to the longitudinal central axis (L). The heat transfer pattern additionally contains turbulent ridges (68) and turbulent depressions (70), while at least one set of turbulent ridges (68) and turbulent depressions (70), at least along the central section (68a, 70a) of its longitudinal lengths extend obliquely relative to transverse imaginary straight lines (66).
EFFECT: increasing efficiency of the flow of the thermal medium.
