Title
(EN) ELEMENT FOR A HEAT EXCHANGER OR HEAT PIPE, AND MANUFACTURING METHOD
(FR) ELÉMENT POUR ÉCHANGEUR DE CHALEUR OU CALODUC, ET PROCÉDÉ DE FABRICATION
Abstract
(EN)
Element (5) for a heat exchanger or heat pipe, comprising a sheet (7) which comprises a plurality of bends (9) parallel to a bending direction (X), the sheet forming successive layers (11) stacked in a stacking direction (Y) substantially perpendicular to the bending direction, the sheet being defined in the bending 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 gaps (39) in the side face, the sheet comprising at least one side portion (41) extending in the bending direction from the sinuous edge. In each of the successive layers, the side portion of the sheet forms embossments (47) comprising at least one projecting portion (49) and at least one recessed portion (51) in the stacking direction, each of the gaps having, perpendicularly to the bending direction, at least one cross-sectional area blocked at least 70% by the embossments.
(FR)
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.
