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 alternatel y cut open, left intact, and flattened so as to form a pattern of three distin ct 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 hea t 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. |
