PLATE HEAT EXCHANGER PLATE AND PLATE HEAT EXCHANGER

摘要

A plate heat exchanger plate (2) with a main heat transfer portion (14) comprising a first area (16) comprising a first field (30) with first corrugations arranged substantially on one side of a straight first line (26) intersecting with second side edges (6a, 6b) and a second field (32) with second corrugations arranged substantially on an opposite side of the first line (26) is provided. The main heat transfer portion (14) comprises a first outer area (18) arranged between a first area (16) and a first of the second side edges (6a) and extends along the first second side edge (6a) between two distribution portions (12a,12b). In the first outer area (18) there are arranged first protrusions and recesses directed in a first general direction in relation to a straight second line (27) parallel to one of first side edges (4a, 4b). A plate (2) with a straight first second edge (6a) may thus be provided when corrugations in the first area (16) are directed in different directions.
