Echangeur de chaleur de faible contrainte et son procede de fabrication

Low stress heat exchanger and method of making the same

Abstract

Un echangeur de chaleur de faible contrainte (50) et son procede de fabrication, consistant a assembler des elements d'echange de chaleur fins (18, 20, 64, 66) sur des supports plus epais (44, 84) en forcant les elements fins (18, 20, 64, 66) a s'etendre tangentiellement a partir d'une surface ayant un rayon de courbure (84) du support (44, 84). Les elements fins (18, 20, 64, 66) sont alors fixes sur le support (44, 84) dans une zone (42, 88) eloignee de la zone (46, 48) ou les elements fins (18, 20, 64, 66) s'etendent tangentiellement a partir du support (44, 84). L'echangeur de chaleur (50) comprend des oreilles de fermeture (14, 16) qui comblent un espace aux extremites de passages (36) du fluide definis par des organes de parois espacees (18, 20).
Low stress heat exchanger (50) and method for making the same wherein thin heat exchange members (18, 20, 64, 66) are joined to thicker support members (44, 84) by causing the thin members (18, 20, 64, 66) to extend tangentially from a radiused surface (84) of the support member (44, 84). The thin members (18, 20, 64, 66) are then secured to the support member (44, 84) in an area (42, 88) remote from the area (46, 48) where the thin members (18, 20, 64, 66) extend tangentially from the support member (44, 84). The heat exchanger (50) includes closure tabs (14, 16) for bridging a space at the ends of fluid passages (36) defined by spaced wall members (18, 20).
