FIELD: heat engineering.
SUBSTANCE: invention relates to the field of heat engineering and can be used in plate heat exchangers. The heat transfer plate (2) comprises a first distribution area (14) provided with a first distribution pattern, a second distribution area (22) provided with a second distribution pattern, and a heat transfer area (26) provided with a heat transfer pattern different from the first and second distribution patterns. The first and second distribution patterns are chocolate-like patterns and comprise distribution ridges (50) and distribution troughs (52). Distribution ridges (50) and distribution troughs (52) of the first and second distribution patterns located closest to the heat transfer region (26) form end ridges (66) and end valleys (68). The upper portion (58) of the heat transfer plate (2) of at least one of the plurality of end ridges (66) along at least a part of its longitudinal extent may have a second width (w2) that is greater than the first width (w1) of the upper portion (58) of the remaining distribution troughs (52), and the lower portion (60) of at least one of the plurality of end valleys (68) along at least part of its longitudinal extent has a fourth width (w4) that is greater than the third width (w3) of the lower portion (60) of the remaining distribution troughs (52).
EFFECT: improving efficiency of fluid distribution.
