Abstract
A brazed plate heat exchanger (10) comprises an end plate (11) and a stack of heat exchanger plates (12, 12a, 12b) provided with a pattern comprising ridges (R) and grooves (G) adapted to form contact points (16) between neighboring heat exchanger plates such that the heat exchanger plates form interplate flow channels for media to 5 exchange heat over the heat exchanger plates, the heat exchanger plates further being provided with port openings (O1-O4) for selective fluid communication with the flow channels, wherein the port openings are surrounded by port opening areas (13) for sealing against a corresponding port opening area of a neighbouring heat exchanger plate, wherein neighboring heat exchanger plates are connected by brazing joints at said contact points (16), wherein the end plate (11) is provided with port openings (O1-O4) and flat areas (14) around the port openings in a common plane, wherein a plurality of ridges (R) of the heat exchanger plates, in an area overlapping any of said flat areas (14) of the end plate (11), are formed with an indentation (15).
