Abstract
A brazed heat exchanger (100, 200) comprises a number of heat exchanger plates (110, 120, 130, 140, 150) provided with a pressed pattern of ridges and grooves to form flow channels for media to exchange heat between neighboring heat exchanger plates (110,120,130,140,150). The flow channels are in selective fluid communication with port openings (160). The port openings (160) are provided with dented surfaces (180; 280) being arranged along an interior circumference of the port openings (160) and comprising ridges (181; 282) and grooves (182; 281), said ridges (181; 282) and grooves (182; 281) being arranged such that a ridge (181; 282) of one heat exchanger plate (110, 120, 130, 140, 150) contacts a groove (182; 281) of a neighboring plate (110,120,130,140,150) to form a honeycomb pattern. The dented surfaces (180; 280) are located such that they at least partly surround the port opening (160), and a gable surface (184) is removed to increase a surface area open to fluid flow from the port openings (160) to the flow channels.
