Beschreibung
Zusammenfassung:	A plate heat exchanger comprises a plate package (2) of heat transfer plates (3) provided with ports (12), which is arranged between two frame plates (4, 5), at least one (4) of the frame plates being provided with connection pipes (7). The invention concerns a support arrangement to avoid bending of a portion that surrounds each of the ports (12) of an outer heat transfer plate (10) in the plate package (2). Each connection pipe (7) on its inside is provided with a lining (9), which is radially movable in the connection pipe (7) and permanently connected with the outer heat transfer plate (10) around its relevant port (12). The support arrangement is constituted by a ring (14) arranged around the lining (9). The ring (14) supports the outer heat transfer plate (10) and abuts against a support surface, which is fixed in relation to the frame plate (4). Echangeur de chaleur à plaques comprenant un ensemble (2) de plaques de transfert thermique (3) pourvues d'orifices (12), situé entre deux plaques de cadre (4, 5) dont au moins une (4) comporte des tubes d'accouplement (7). L'invention concerne un dispositif de support servant à empêcher l'incurvation d'une partie entourant chacun des orifices (12) d'une plaque de transfert thermique extérieure (10) de l'ensemble (2). L'intérieur de chaque tube d'accouplement (7) présente une doublure (9) mobile radialement dans ledit tube (7) et accouplée en permanence à la plaque de transfert thermique extérieure (10) autour de son orifice correspondant (12). Ce dispositif de support est constitué par un anneau (14) disposé autour de la doublure (9). Cet anneau (14) supporte la plaque de transfert thermique extérieure (10) et vient en butée contre une surface de support fixe par rapport à la plaque de cadre (4).
