The invention relates to a heat exchange system (1) having a heat exchanger (2) for the exchange of heat between a fluid (3) and an environmental atmosphere. The heat exchanger (2) in this respect includes an inlet passage (4), an outlet passage (5) and a heat transfer device (6) having a plurality of micro-passages (61), with the inlet passage (4) being in flow communication with an inlet segment (62) of the heat transfer device (6) and the outlet passage (5) being in flow communication with an outlet segment (63) of the heat transfer device (6) such that the fluid (3) for the exchange of heat with the environmental atmosphere can be supplied from the inlet passage (4) via the inlet segment (62), through the plurality of micro-passages (61) of the heat transfer device (6), and via the outlet segment (63) to the outlet passage (5). In accordance with the invention, the heat exchange system (1) includes a compensation means (7) for the compensation of thermomechanical strains. The invention furthermore relates to a method for the manufacture of a heat exchange system (1) in accordance with the invention.

L'invention concerne un système d'échange de chaleur (1) doté d'un échangeur de chaleur (2) et destiné à échanger de la chaleur entre un fluide (3) et l'atmosphère ambiante. L'échangeur de chaleur (2) comprend un canal d'admission (4), un canal d'évacuation (5) et un dispositif (6) de transfert de chaleur qui présente une pluralité de microcanaux (61), le canal d'admission (4) étant relié à écoulement à un segment d'admission (62) du dispositif (6) de transfert de chaleur et le canal d'évacuation (5) à un segment d'évacuation (63) du dispositif (6) de transfert de chaleur de telle sorte que le fluide (3) puisse en vue de l'échange de chaleur être amené dans la pluralité de microcanaux (61) du dispositif (6) de transfert de chaleur avec l'atmosphère ambiante depuis le canal d'admission (4) par l'intermédiaire du segment d'admission (62), et dans le canal d'évacuation (5) par l'intermédiaire du segment d'évacuation (63). Selon l'invention, le système (1) d'échange de chaleur comprend un moyen de compensation (7) qui compense les contraintes thermomécaniques. L'invention concerne par ailleurs un procédé de fabrication d'un système (1) d'échange de chaleur selon l'invention.
