Claim:
1. A heat transfer plate having a central extension plane and comprising a first end area, a heat transfer area and a second end area arranged in succession along a longitudinal center axis of the heat transfer plate, which longitudinal center axis divides the heat transfer plate into a first and a second half delimited by a first and second long side, respectively, the first end area comprising an inlet port hole arranged within the first half of the heat transfer plate, a distribution area and a transition area, the transition area adjoining the distribution area along a first borderline and the transition area adjoining the heat transfer area along a second borderline, the distribution area having a distribution pattern of distribution projections and distribution depressions in relation to the central extension plane, the transition area having a transition pattern of transition projections and transition depressions in relation to the central extension plane and the heat transfer area having a heat transfer pattern of heat transfer projections and heat transfer depressions in relation to the central extension plane, the transition pattern differing from the distribution pattern and the heat transfer pattern, the transition projections comprising transition contact areas arranged for contact with another heat transfer plate, and an imaginary straight line extending between two end points of each transition projection with an angle in relation to the longitudinal center axis, wherein the angle is varying between the transition projections and increasing in a direction from the first long side to the second long side.
