Abstract

See full text

A heat transfer plate comprises upper, center and lower end portions, the latter adjoining the center portion along an upper borderline and comprising first and second portholes and a distribution area having a distribution pattern. The distribution pattern comprises distribution ridges, a respective top portion of which extends in a plane and has rounded first, second, third and fourth corners. The distribution ridges extend along plural separated imaginary ridge lines from the upper borderline towards the first porthole. For each of a number of the distribution ridges extending along a top ridge line closest to the second porthole, the first corner's curvature radius is larger than the second corner's curvature radius, the first/second corners are on opposite sides of the top ridge line, the second corner is closer to the second porthole than the first corner, and the first/third corners are on the same side of the top ridge line.
