<p>A plate heat exchanger plate with a main heat transfer portion comprising a first area comprising a first field with first corrugations arranged substantially on one side of a straight first line intersecting with second side edges and a second field with second corrugations arranged substantially on an opposite side of the first line is provided. The main heat transfer portion comprises a first outer area arranged between a first area and a first of the second side edges and extends along the first second side edge between two distribution portions. In the first outer area there are arranged first protrusions and recesses directed in a first general direction in relation to a straight second line parallel to one of first side edges. A plate with a straight first second edge may thus be provided when corrugations in the first area are directed in different directions.</p> |
