A HEAT EXCHANGER PLATE AND A PLATE HEAT EXCHANGER

摘要

A heat exchanger plate (2) comprises a heat exchanger area (11), at least two portholes (12) each having a diameter (D), and at least two porthole areas (13). Each of the portholes is surrounded by a respective one of the porthole areas. The porthole areas are separated from each other. Each porthole area comprises a corrugation of beams (20). Each of the beams has an end and extends along a respective extension direction (23) towards the porthole. The extension direction of each of the beams forms an acute angle (±) to a radial line (25) through the end of the beam.
