The heat exchanger has heat exchange plates (33) which, in the case of at least one series of aligned inflow or outflow openings (28) over a part of the opening edge, are provided with collars (29) which are integral with the plate and which extend slightly obliquely with respect to the perpendicular to the plates and are formed in a straight or stepped manner. The collars of adjacent plates are positively nested one inside the other, thus forming the plate pack, so as to prevent transverse displacements between adjacent plates. <IMAGE> |
