Beschreibung
Zusammenfassung:	The invention relates to a heat exchanger comprising a casing (2) inside which is housed, and fastened by brazing, a heat exchange assembly (3) comprising a stack of heat exchange plates, each plate (4) having at least one edge (14) for brazing to the casing (2). The heat exchanger is characterized by the fact that it includes means, called unfastening means (20, 21, 22, 23), designed to prevent the casing from being brazed to at least a portion of the edge (14) of at least one end plate (4E) of the stack (3). By virtue of the invention, the heat exchanger is more flexible and absorbs thermal stresses better.
