    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 neighbouring 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 neighbouring 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), wherein said indentations (15) of a heat exchanger plate (12, 12a) adjacent the end plate (11) connect a flow channel, formed between the end plate and the adjacent heat exchanger plate (12, 12a), with a neighbouring flow channel to allow distribution of media between them. A brazing joint for connecting neighbouring heat exchanger plates is arranged between the port opening area (13) and at least one of said indentations (15).

    Abstract: A heat exchanger (10) with a front group of heat exchange conduits (40) extending between a front inlet tank (12) and a front outlet tank (16). A rear group of heat exchange conduits (42) extend between a rear inlet tank (20) and a rear outlet tank (24). A reinforcing plate (50A) is adjacent to the front group of heat exchange conduits (40) and the rear group of heat exchange conduits (42) to restrict twisting thereof. A first stress-relief area (60A) of the reinforcing plate (50A) is proximate to, and spaced apart from, both the front inlet tank (12) and the rear inlet tank (20). A second stress-relief area (60B) of the reinforcing plate (50A) is proximate to, and spaced apart from, both the front outlet tank (16) and the rear outlet tank (24).
