The present invention is a cross-flow evaporator adapted to generate vapor from the heat of the exhaust gases from an internal combustion engine. The evaporator is constituted, among other elements, by two plates spaced from one another which contain chambers. The heat exchange tubes alternately communicate the chambers of both plates, establishing a specific path for the fluid intended to change phase. The tubes extending between the chambers of the two plates are arranged transverse to the flow of the hot gas. This evaporator is suitable for heat recovery systems using a Rankine cycle, making use of the heat from the exhaust gases. 1. An evaporator for the evaporation of a first fluid by means of the heat provided by a second fluid , the second fluid being a hot gas , wherein said evaporator comprises:{'b': 1', '2', '1', '2', '1', '1', '2', '1, 'a first plate () and a second plate () facing one another and arranged spaced from one another, defining an inner face, the face facing the other plate, and an outer face opposite the inner face; wherein each of the plates (, ) comprises a plurality of chambers (., .);'}{'b': 4', '5', '1', '1', '2', '1', '1', '2, 'an intake manifold () of the first fluid and an exhaust manifold () of the first fluid situated in fluid communication with one another and with at least one different chamber (., .) of any of the plates (, );'}{'b': 3', '3', '1', '1', '1', '2', '1', '2', '1', '1', '2', '1', '1', '2', '1', '1', '2', '1', '1', '2', '3', '1', '1', '2', '1', '4', '5, 'a plurality of heat exchange tubes () wherein each of the heat exchange tubes () extends between a chamber (.) of the first plate () and a chamber (.) of the second plate (); wherein each chamber (., .) of one plate (, ) is in fluid communication with two or more chambers (., .) of the other plate (, ) by means of at least two heat exchange tubes (), except the chambers (., .) in fluid communication with the intake manifold () or the exhaust manifold ();'}{'b': 3', '4 ...
