Abstract
A brazed plate heat exchanger (100; 200) comprises a number of heat exchanger plates (120a-120h; 201-204) provided with a pressed pattern of ridges (R) and grooves (G) adapted to keep the plates on a distance from one another by providing contact points between crossing ridges (R) and grooves (G) of neighbouring plates under formation of interplate flow channels for media to exchange heat, said interplate flow channels being in selective fluid communication with first, second, third and fourth large port openings (O1, O2, O3, O4; 210a, 210b, 210c, 210d) and first and second small port openings (SO1, SO2) for letting in fluids to exchange heat, characterized in that fluid passing between the first and second large port openings (O1, O2; 210a, 210b) exchanges heat with fluids passing between third and fourth port openings (O3, O4; 210c, 210d) over a first heat exchanging portion of each plate and fluid passing between the first and second small port openings (SO1, SO2) over a second portion of each plate.
