The heat exchanger includes a pair of corrugated plates (a, b) connected to one another such that the crests of their respctive corrugations (25, 26) contact. Edges (7, 7') of the sheets (a, b) that correspond to the faces of the cylindrical core (1) formed from coiling the sheets (a, b) are bent and connected such that a substantially continuous and flat wall (80) is formed between the two sheets (a, b). Portions (85) of the wall (80) are alternately cut open, left intact, and flattened so as to form a pattern of three distinct angular sectors (100, 200, 300) on the face of the core (1). These angular sectors respectively include cut-open sectors (100) configured to pass a heat transfer fluid therethrough, platform sectors (200) configured for the mounting of headers (8) thereon, and flattened wall sectors (300) creating gaps (90) configured to pass a heat transfer fluid therethrough.
L'invention concerne un échangeur thermique comprenant une paire de plaques ondulées (a, b) reliées l'une à l'autre de telle sorte que les crêtes de leurs ondulations respectives (25, 26) entrent en contact. Les bords (7, 7') des feuilles (a, b) correspondant aux faces du noyau cylindrique (1) formé par enroulement desdites feuilles (a, b) sont courbés et reliés de manière à former une paroi (80) sensiblement continue et plate entre les deux feuilles (a, b). Des portions (85) de la paroi (80) sont successivement découpées, conservées en l'état, et aplanies de manière à former une configuration à trois secteurs angulaires (100, 200, 300) distincts sur la face du noyau (1). Ces secteurs angulaires respectivement comprennent des secteurs découpés (100) conçus pour laisser traverser un fluide caloporteur; des secteurs plate-forme (200) conçus pour le montage des entrées-sorties (8); et des secteurs de paroi (300) aplanis formant des cavités (90) conçues pour laisser traverser le fluide caloporteur.
