A heat exchanger for the heat exchange between a first fluid and a second fluid, which achieves an unusual strength comprises a plurality of casings (2), of substantially flattened shape and of predetermined width (L), arranged in a pile (2a), with an air space (3) defined between adjacent casings in the pile, and each formed from two half-shells (6) welded along a peripheral strip (6a), said casings (2) being in fluid communication with each other through respective holes (7) opening into said air space (3), and at least one spacer (8), substantially of the sleeve type, in said air space (3), made integral at the top end with said adjacent casings around the respective holes (7) opening into said air space (3).

La présente invention a trait à un échangeur de chaleur pour l'échange thermique entre un premier fluide et un deuxième fluide, présentant une tenue mécanique inhabituelle comportant une pluralité de tubes (2), de forme sensiblement plane et de largeur prédéterminée (L), disposés en un empilement (2a), avec un espace d'air (3) défini entre les tubes dans l'empilement, et chacun formé à partir de deux demi-coques (6) soudées le long une bande périphérique (6a), lesdits tubes (2) étant en communication fluidique les uns avec les autres à travers des trous respectifs (7) débouchant dans ledit espace d'air (3), au moins une entretoise (8), sensiblement du type gaine, dans ledit espace d'air (3), solidaire à l'extrémité supérieure desdits tubes adjacents autour des trous respectifs (7) débouchant dans ledit espace d'air (3).
