The invention relates to a plate heat exchanger, which comprises a plate pack formed by corrugated heat exchange plates with openings for the flow of a first and a second heat exchange medium. The outer shell of the plate heat exchanger (1) has been formed by arranging separate strips (9, 9') in the outer edge of the plate pack (2) so that the outer surfaces of the strips (9, 9') are substantially in the same plane with the outer edges of the heat exchange plates (6, 6'), and by welding the strips (9, 9') and the outer edges of the heat exchange plates (6, 6') to each other. L'invention se rapporte à un échangeur de chaleur à plaques, qui comprend un bloc de plaques formé par des plaques d'échange de chaleur ondulées dotées d'ouvertures pour l'écoulement d'un premier et d'un second agent d'échange de chaleur. La coque extérieure de l'échangeur de chaleur (1) à plaques a été formée par l'agencement de bandes (9, 9') distinctes dans le bord extérieur du bloc (2) de plaques de sorte que les surfaces extérieures des bandes (9, 9') soient sensiblement dans le même plan que les bords extérieurs des plaques d'échange de chaleur (6, 6'), et par le soudage des bandes (9, 9') et des bords extérieurs des plaques d'échange de chaleur (6, 6') les uns aux autres.
