Titanium or titanium alloy heat exchanger

Abstract

The invention relates to a heat exchanger of the plate-and-fin type configured to bring into heat-exchange relationship at least one refrigerant fluid and at least one heat-originating fluid, said exchanger comprising a plurality of plates arranged parallel to each other and to a longitudinal direction so as to define between said plates a plurality of passages adapted for the flow of the refrigerant fluid or the heat-originating fluid along the longitudinal direction, heat exchange structures with fins being arranged within at least part of the passages, the plates and the heat exchange structures are formed wholly or partly of titanium or a titanium alloy and wherein the plates and the heat exchange structures are assembled by brazing by means of a brazing agent comprising a eutectic alloy.
