Abstract

L'invention concerne un échangeur de chaleur présentant une efficacité améliorée grâce à l'utilisation de multiples tuyaux d'amenée. L'échangeur de chaleur (1) met en œuvre un échange de chaleur entre un premier fluide (11) s'écoulant dans des premiers tuyaux (41) internes et un deuxième fluide (21) s'écoulant dans des tuyaux externes (42). L'échangeur de chaleur (1) comporte: un corps (6) qui contient des tuyaux (4) de transfert de chaleur; une première partie (12) d'entrée dans laquelle les tuyaux internes (41) des tuyaux (4) de transfert de chaleur se déploient depuis les tuyaux extérieurs (42) afin de faire entrer le premier fluide (11) à partir des extrémités des tuyaux intérieurs (41) déployés; une deuxième partie (22) d'entrée qui fait entrer le deuxième fluide (21) entre les tuyaux extérieurs (42) et les tuyaux intérieurs (41) des tuyaux (4) de transfert de chaleur, depuis les périphéries extérieures des parties déployées des tuyaux intérieurs (41); et une troisième partie (32) d'entrée, qui et isolée de la deuxième partie (22) d'entrée et fait passer un troisième (31) à travers les intervalles (5) entre les périphéries extérieures des tuyaux (4) de transfert de chaleur.
