(54) A plate-type heat exchanger


(57) Each couple of plates (1) defines a first canal (3) for a fluid under pressure by means of welded ribbing (2) that distance and reinforce the plates (1) and are parallel to the flow of said fluid and bears a continuous fin with a wave shape (4) perpendicular to the direction of said fluid, welded on each of its external surfaces, to define a second canal (5) for a second fluid associated to an opposite and equal fin (4) borne on a plate (1) of an adjacent couple, each couple of plates being free from the others and hence that can be singly extracted from the exchanger.
