Abstract
L'invention concerne un refroidisseur intermédiaire (1) comprenant un premier tuyau d'entrée (61), un premier tuyau de sortie (62), un second tuyau d'entrée (63) et un second tuyau de sortie (64) disposés sur les parois externes d'un conduit (30). Au moins un tuyau parmi le premier tuyau d'entrée (61), le premier tuyau de sortie (62), le second tuyau d'entrée (63) et le second tuyau de sortie (64) est disposé sur une paroi externe du conduit (30) au niveau d'un côté dans une direction d'empilement (H). Au moins un autre tuyau, différent du tuyau disposé sur la paroi externe du conduit (30) au niveau du côté dans la direction d'empilement (H), parmi le premier tuyau d'entrée (61), le premier tuyau de sortie (62), le second tuyau d'entrée (63) et le second tuyau de sortie (64), est disposé sur la paroi externe du conduit (30) au niveau de l'autre côté dans la direction d'empilement (H).
