Abstract

Elément pour échangeur de chaleur ou caloduc, et procédé de fabrication Elément (5) pour échangeur de chaleur ou caloduc, comprenant une feuille (7) comportant une pluralité de plis (9) parallèles à une direction de pliage (X), la feuille formant des couches successives (11) superposées dans une direction de superposition (Y) sensiblement perpendiculaire à la direction de pliage, la feuille étant délimitée dans la direction de pliage par au moins un bord sinueux (33) définissant au moins une face latérale de l’élément, les couches successives définissant entre elles une pluralité de canaux de circulation pour des fluides dans la direction de pliage, les canaux de circulation définissant respectivement des interstices (39) dans la face latérale, la feuille comportant au moins une partie latérale (41) s’étendant dans la direction de pliage depuis le bord sinueux. Dans chacune des couches successives, la partie latérale de la feuille forme des reliefs (47) comportant au moins une portion en saillie (49) et au moins une portion en creux (51) dans la direction de superposition, chacun des interstices ayant, perpendiculairement à la direction de pliage, au moins une section de passage obstruée à au moins 70% par lesdits reliefs. Figure pour l'abrégé : Figure 3Element for heat exchanger or heat pipe, and manufacturing method Element (5) for heat exchanger or heat pipe, comprising a sheet (7) having a plurality of folds (9) parallel to a fold direction (X), the sheet forming successive layers (11) superimposed in a superimposed direction (Y) substantially perpendicular to the folding direction, the sheet being delimited in the folding direction by at least one sinuous edge (33) defining at least one side face of the element, the successive layers defining between them a plurality of circulation channels for fluids in the bending direction, the circulation channels respectively defining interstices (39) in the side face, the sheet comprising at least one side part (41) extending in the folding direction from the meandering edge. In each of the successive layers, the lateral part of the sheet forms reliefs (47) comprising at least one projecting portion (49) and at least one recessed portion (51) in the direction of superposition, each of the interstices having, perpendicularly in the direction of folding, at least one passage section obstructed at least 70% by said reliefs.
